For convenient bottling of bottled liquid into bottles of different volumes, it is convenient to use a special water pump, which has several design modifications and prevails in free sale. Prices are different, but in many cases such a device becomes simply indispensable. More often, a pump is needed for bottles of 19 liters, especially convenient for storing water. What is this spare part, how to use it correctly in practice?

What is a water pump

Structurally, this is a removable device that is conveniently attached to the neck of the bottle and is necessary for quickly pumping out the liquid. In this way, you can significantly simplify the process of filling any dishes with liquid. The bottle pump allows you to pump water in portions - with each press, which is especially important when using coolers. In fact, this is a water pump that facilitates the work of a person, but at the same time requires high-quality care and maintenance in sterile cleanliness when not needed.

Pump device

You can choose such a design from a photo from a catalog on thematic sites, order and buy in an online store, but you first need to find out how it works and on what principle the model you like is arranged, what are the main pros and cons of such an acquisition, read the instructions. So, the water pump device provides for the following structural elements:

pump pump (self-priming mechanism);
two nozzles - one suction, the second supply;
rotating drum;
air filter;
batteries (in electric water pumps);
cigarette lighter socket;
adapter;
carrying handle (not on all pumps).

A pump for bottled water may differ in design or in the mechanism of action. For example, electric models that use mains voltage and minimize physical labor are noticeably popular. However, a manual water pump is also well known, which has been successfully operating for more than a decade with the help of human efforts. The latter design is inexpensive, but its functions are noticeably limited.

Electric water pump

It is an economical design that is simple and convenient to use for drinking water. An electric water pump is inexpensive, and the final price depends on the design features and the manufacturer's rating. The electric pump is battery operated and can pump up to 300 gallons of 19 liters. Such a pump for a cooler is especially relevant, which works quickly without interruption with uninterrupted power supply. Below are the most popular models approved by modern buyers. It:

price - 1,800 rubles;
characteristics - bottle volume - 18.9 l, water supply by a submersible pump, the presence of a switch to spill water;
pluses - light and compact, easy to use;
cons - high price.

Mechanical water pump

This is a conventional hand pump, which requires some effort to fill the eggplant. The mechanical pump pumps liquid out of the bottle in portions, however, this requires a slight pressure of the hand. Even a child can cope with such a task, and the indicated design is suitable for volumes of 5-10 liters. Below are a few mechanical pumps that have "running" characteristics. It:

model name - Dolphin;
price - 1,800 rubles;
characteristics - mechanical work Dolphin, capacity - 5-10 liters;
pluses - light and easy to transport, available in use;
cons - high price.

pluses - light and mobile, simple for everyday use;
cons - high price.

Continuing to study pumps, below is another mechanical design for pumping water:

name - Vatten No. 2;
price - 750 rubles;
characteristics - mechanical model, classic design, universal in properties;
pluses - light and comfortable for everyday use;
cons - none.

How to choose a water pump

Volume of liquid. If we are talking about large portions, it is better to use an electric model, which is economical to operate and runs on two batteries. Mechanical pumps are suitable for coolers and household needs when a person needs to perform a couple of movements.
Manufacturer. You should not get hung up on imported products, domestic-made pumps are also very popular, they are highly efficient and reliable. For example, the companies Aquaphor, Akvik have proven themselves well.
Price. This issue is decided purely individually, but in order for the pump to last a long time, it is better not to save on such an acquisition. But the mechanical model can be taken cheaper, anyway, there is nothing to break in the design.

In the event of a breakdown or for other reasons, the pump may not pump water.

It is quite possible to independently figure out why the pump does not pump water from the well. All reasons are divided into 3 categories. The first includes the hydraulic characteristics of the soil. For example, if the pump is actively pumping river water, this is a sign that its power needs to be adjusted. The second category of causes - breakdowns due to the influence of environmental factors. The so-called human factor completes the list.

The causes of the problem often lie in the mistakes made at the stage of drafting the project. For example, a motor pump pumps several times more than a source can provide. This leads to increased energy consumption and rapid wear of the undercarriage of the device. First you need to open the passport, which indicates the performance of the device. It is measured in m3 / h. This indicator is compared with the debit of the well. If the water pump is more powerful than the well, it is better to replace it.

If the motor pump does not pump water, you should first carefully check the pump

The longer the “dry run” takes place, the more the unit buzzes.

In order to objectively evaluate technical condition system, you need to pay attention to the following factors:

You can not immediately turn off all points of water intake;
The water pump "Dzhileks" will last longer if watering personal plot will not resemble a flood in its volume;
The larger the diameter of the pipes and hoses, the lower the pressure level.

The human factor occupies a leading position among all the reasons why pump equipment does not work properly. At the design stage, all details and environmental conditions must be taken into account. This is in the interests of the user, otherwise you will have to pay dearly for unscheduled repairs.

Pressure and electrical problems

A vacuum device lifts water from a certain depth. The lower the aquifer lies, the more power is needed. Errors occur at the stage of determining the technical parameters of the pump. AT technical description it is indicated from what maximum depth it will raise the liquid.

It is better to take a model with a small margin - within 20% of the required level. This will save you from costly manipulations if the aquifer sinks.

A submersible pump can make noise for a long time, trying unsuccessfully to raise water. The process will stop as soon as the thermostat works. If this does not happen, then the unit will fail due to overheating.

The pump may not pump water if there are problems with pressure

The following hydraulic tips will help reduce the likelihood of such malfunctions:

10 m of a horizontal tube is equated to 1 m of a vertical;
The presence of an increased level of resistance requires changing the above proportion - 5: 1;
If a person finds it difficult to independently make calculations, then you need to call a professional engineer.

A drop in the voltage level in the network leads to the fact that the pump begins to poorly deliver water from the well to the surface. Problems begin at the moment when the voltage level goes beyond the permissible limit - 220 V +/- 10%. At this point, the pumping station may stop turning on altogether. If it still comes into working condition, the efficiency will be negligible. A voltage stabilizer will help to fix this problem.

If the pump is not working properly

As soon as a person notices that the device pumps water poorly or does not do it at all, you need to pay attention to the pipes. Often clogs form in them, reducing the level of pressure. It is less common to blame valves or filters. Engineers pay attention to the fact that this kind of problem occurs after a system has been idle for a long time or improperly assembled. For example, foreign objects or dirt got into the pipe. Gradually it takes away the mixer and the cartridge. Continuing the topic of garbage, we need to mention the need to look at the bottom of the well.

The more sand, silt and other sources of pollution there, the more often a routine inspection is carried out. Reestablish borehole pump only one way is possible. It is turned off and then removed to the surface.

In addition, hydraulics give a few more practical recommendations:

If the device sucks weakly, then it must be washed under pressure;
It is necessary to allow the unit to work for some time in the tank without a check valve installed;
You should always listen to the sound of a running motor - the quieter it is, the bigger the problem is coming.

Another problem associated with the piping system concerns insufficient sealing or physical damage. In the first case, we are talking about the mechanical disconnection of a part of the pipe or the wear of the gaskets. In such a situation, you need to do what he advises. common sense, to perform a local replacement. More time will have to be spent when water from the well does not flow as a result of pipe damage.

If a broken device does not raise water from the well

Signs that the unit is out of order will be a permanent hum and lack of water. You can determine why the deep pump pumps liquid poorly, you can do it yourself. To do this, it is necessary to inspect the mechanical part of the injection element. If we are talking about a centrifugal type of pump, then in 9 cases out of 10 the problem is localized at the level of the plastic impellers of the shaft. They scroll too weakly, which reduces the level of traction several times.

Pumps operating on the basis of the vibration principle become unusable due to a broken stem or broken piston. Most of these problems are due to wear and tear or human error.

Regardless of the reason, the device must be disconnected from the network.

A broken pump can not lift water from a well

The further course of action is as follows:

Unscrew the part, the quality of which is in doubt;
Carry out a detailed inspection;
If the unit is still under warranty, then it is better to ask specialists to figure out why the pump does not work well;

Cold can provoke a temporary malfunction - as soon as the inner surface of the device is free of ice, the pumping equipment will return to normal. You can remove the effects of frost yourself. To do this, use the methods recommended by the manufacturer. It must be remembered that the problem must be fixed as soon as possible. The earlier the repair is made, the less likely it is to lose the power of the product. The second important factor will be the regular maintenance of all parts of the device.

Submersible pumps have to work in difficult conditions. They are constantly exposed to water, vibration, low temperature, abrasive particles, etc. But despite the fact that the units are made of parts with a large margin of safety, various malfunctions appear in them over time. To repair water pumps with your own hands, you need to familiarize yourself with the main symptoms that indicate certain breakdowns in the equipment.

If failures are noticed in the operation of a submersible pump, then it is not always necessary to remove it from the well for inspection. This recommendation only applies to pumping stations where pressure switch installed. It is because of him that the device may not turn on, turn off or create poor water pressure. Therefore, the operability of the pressure sensor is first checked, and after that, if necessary, the pump is removed from the well.

Important! In the case of submersible pumps operating without hydraulic accumulators, they should always be removed from the shaft at the slightest sign of failure.

Water pump malfunctions will be easier to diagnose if you first familiarize yourself with the most common failures of this unit.

The pump is not working

The reasons that the pump does not work may be as follows.

Electrical protection tripped. In this case, disconnect the machine from the mains and turn on the machine again. If it knocks it out again, then the problem should not be sought in the pumping equipment. But when the machine is turned on normally, do not turn the pump on again, you must first find the reason why the protection worked.
Fuses blown. If, after replacement, they burn out again, then you need to look for the cause in the power cable of the unit or in the place where it is connected to the mains.
Cable damage has occurred under water. Remove the device and check the cord.
The pump dry-run protection has tripped.". Before starting the machine, make sure that it is immersed in the liquid to the required depth.

Also, the reason that the device does not turn on may lie in the incorrect operation of the pressure switch installed in pumping station. The start pressure of the pump motor needs to be adjusted.

The pump works but does not pump

There may also be several reasons why the device does not pump water.

Shut-off valve closed. Turn off the machine and slowly open the tap. In the future, pumping equipment should not be started with the valve closed, otherwise it will fail.
The water level in the well has dropped below the pump. It is necessary to calculate the dynamic water level and immerse the device to the required depth.
Check valve stuck. In this case, it is required to disassemble the valve and clean it, if necessary, replace it with a new one.
Inlet filter clogged. To clean the filter, the hydraulic machine is removed and the filter mesh is cleaned and washed.

Low machine performance

Advice! If the performance of pumping equipment drops, the mains voltage should be checked first. It is because of its reduced value that the engine of the unit cannot gain the necessary power.

Also, performance degradation causes:

partial clogging of valves and valves installed in the water supply system;
partially clogged lifting pipe of the apparatus;
pipeline depressurization;
incorrect adjustment of the pressure switch (applies to pumping stations).

Frequent switching on and off of the device

This problem occurs if the submersible pump works in tandem with a hydraulic accumulator. In this case, frequent starts and stops of the unit can be provoked by the following factors:

in the hydraulic tank there was a decrease in pressure below the minimum (by default it should be 1.5 bar);
there was a rupture of a rubber pear or diaphragm in the tank;
the pressure switch is not working properly.

Water is supplied with pulsation

If you notice that the water from the tap does not flow in a constant stream, then this is a sign that the water level in the well has dropped below dynamic. It is necessary to lower the pump deeper if the distance to the bottom of the shaft allows this.

The buzz of the machine is heard, but the water does not pump

If the pump is buzzing, and at the same time water is not pumped out of the well, then there may be several reasons:

there was a “gluing” of the impeller of the apparatus with its body due to long-term storage devices without water;
defective engine start capacitor;
dipped voltage in the network;
the impeller of the pump is jammed due to dirt collected in the body of the apparatus.

The unit does not turn off

If the automation does not work, the pump will work without stopping, even if excessive pressure is created in the hydraulic tank (seen from the pressure gauge). It's all to blame pressure switch out of order or incorrectly adjusted.

The nuances of breakdowns depending on the brand of the pump

When operating pumps from different manufacturers, it was noticed that some brands of devices are often subject to the same breakdowns. From this it follows that these models of units have their own distinctive features in terms of the occurrence of malfunctions.

Aquarius

Aquarius pumps have prone to overheating, especially if they work in wells of small depth. If a cheap model breaks down, its repair costs about 50% of the cost of a new device. If the device is out of order, then it is easier to throw it away than to repair it.

Grundfos

Most models of this manufacturer have valve system. Also around the engine there is a special thermal insulation. Sometimes pump failures occur due to the failure of the listed parts. Because the thermal pad is around the motor, it will need to be removed from the housing for repair.

Baby

Apparatuses "Kid" are products of domestic manufacturers. The cost of repairing units of this brand is not high, and most of the breakdowns are repaired by the owners of the devices themselves. The main failure often encountered in this pump is loud noise during operation of the hydraulic machine without pumping out the liquid. This behavior of the device means that there was a rupture of the central axis holding the anchor and the membrane.

Gilex

The engine in the vortex and rotary pumps "Dzhileks" is oil-filled. Therefore, a frequent breakdown of these units is oil leakage from the engine. It can only be topped up at a service center.

Important! Many on the Internet advise using transformer oil or regular glycerin instead of the original oil filler. Doing this is highly discouraged, of course, unless you set yourself the goal of spoiling the technique in an unusual way.

Brook

There is an opinion that the operation of the drainage pumps "Brook" can continue without interruption for 7 hours or more. This is explained by the peculiarity of their design, which meets all European standards. Despite this, the device overheated as well as pumps from other manufacturers. Therefore, it is recommended that after every 2-3 hours of operation of the device, give it time to “rest”.

Marquis (Marcus)

The owners of the Marcus well pump sometimes notice that the device turns on only after a slight blow either on the pipe leading to it, or after hitting the hydraulic machine itself. This error is explained by “ souring” of the impeller, which will have to be cleaned by disassembling the unit.

How to disassemble the unit to diagnose a breakdown

In case of pump breakdowns requiring replacement of parts located inside its housing, disassembly of the unit will be required. A submersible pump consists of a motor compartment and a compartment with one or more impellers, the purpose of which is to capture water. Below is a diagram of the device of that part centrifugal pump where the impellers are installed.

As can be seen from the figure, the impellers are mounted on the shaft of the unit. The more of them, the higher the pressure created by the pump. In the second compartment of the hydraulic machine is located rotary engine. It is in a sealed case, and to open it, you need to know some of the nuances.

So, in order to move from theory to practice and disassemble the pump, follow these steps (depending on the manufacturer, the design of the unit may differ).

Unscrew the 2 screws holding the mesh of the device.
Remove the mesh and turn the motor shaft by hand. If it does not spin, then the problem may be either in the engine compartment or in the pumping part of the device.
First you need to disassemble the pumping part of the device. Unscrew the 4 screws holding the power cable channel and disconnect it from the machine body.
Next, unscrew the 4 nuts holding the pump flange.
After unscrewing the fasteners, separate the pumping part of the apparatus from the engine. On the this stage it is possible to determine in which section the jamming has occurred. If the shaft of the pump compartment does not rotate, then this assembly must be disassembled.
Unscrew all fasteners holding the lower flange of the pump part of the unit.
An adapter must be screwed into the fitting located at the top of the block, which will help keep the threads from damage.
Secure the pump in a vise.
Having picked up a suitable tool, unscrew the bottom flange.
The impeller assembly can now be pulled out and inspected for faults.
Next, you should check the support shaft for wear or play.
To replace (if necessary) the impellers, it is necessary to fix the shaft in a vice and unscrew the top nut.
At the next stage, the blocks are removed, washed and, if necessary, replaced with new ones.
The assembly of the pumping part of the apparatus is carried out in the reverse order.
To disassemble the electric motor, it must also be fixed in a vise.
Next, remove the plastic flange protection by unscrewing the fasteners.
Remove the retaining ring holding the cover with a pair of pliers.
Remove the cover using a slotted screwdriver.
Remove the rubber membrane from the housing.
Remove the capacitor.
At this stage, you can check the oil level, its quality, identify the cause of jamming, etc. The engine block is assembled in the reverse order.

Replacement and repair of defective parts

Now that you know how the hydraulic machine is disassembled, you can try to repair the submersible pump with your own hands.

Basically, the blocking of the impellers occurs due to filling them with sand or due to the formation of dirt deposits on them. In addition, the impellers can be soldered together when high temperature in the unit when the pump is idling (dry running). To repair this section of the unit, the impeller(s) must be removed and accumulated dirt removed. If the impellers are damaged, they will need to be replaced with new ones.

Engine

Self-repair of the pump motor is not recommended, since the diagnosis of this unit and subsequent repair require special knowledge and the necessary equipment.

In some models of pumps, in order to remove the motor, it will be necessary to press it out using special equipment. Oil seal and bearing replacement also carried out in the service center.

If a engine hums and won't start then check the capacitor. It is located in the pump block in which the motor is installed.

Advice! Before disassembling the engine block, try to rotate its shaft with the pump block disconnected. If the shaft rotates, then the reason may lie in the jamming of the impellers.

But when the impeller shaft rotates without problems, then in order to remove the hum in the water pump, you should disconnect the capacitor and change it to a new one. Of course it's better check this part with a multimeter, since similar symptoms can be caused by a short circuit in the motor windings.

The water pump engine is located in a special glass filled with oil, and by its condition it is possible to determine some breakdowns in the electric motor unit.

The oil has a characteristic, unpleasant odor. This means that the engine is still in working condition, but it worked with large overloads.
cloudy oil- water has entered the motor housing due to a crack in the housing or failure of the stuffing box (cuff).
Black oil with an unpleasant odor. In this case, we can say with great certainty that the varnish on the engine coils burned.

Important! Normally, the oil should be clear. Its quantity is determined by the model of the unit. On average, the volume of oil poured into the chamber is at the level of 0.5 liters.

If, when opening the engine, the above changes in oil quality were noticed, then you first need to repair this unit, and only after that fill in new grease.

What is the phenomenon of cavitation

Everyone knows what is dissolved in water some gases. When a liquid moves at a certain speed, rarefaction zones sometimes form in it. In these zones of low pressure, gas bubbles begin to emerge from the water. After bubbles enter the zone high pressure they collapse. This process occurs with the release of a large amount of energy, from which the impellers and the pump snail are destroyed. The following photo shows the impeller of the unit, destroyed by cavitation.

The energy of collapsing bubbles can create shock waves causing vibration. It spreads throughout the unit and affects not only the impeller, but also the bearings, shaft and seals, from which these parts quickly become unusable.

The cavitation effect can most often be observed in pumping stations that operate on suction. In such systems, the impeller creates a vacuum, due to which water rises through the hose from the well. But if there is a lack of liquid at the inlet to the pump, then an excessive vacuum occurs in the impeller zone, provoking the occurrence of cavitation.

Important! The most obvious signs of cavitation are the vibration of the pipes and the pump itself, as well as increased noise during its operation. If no measures are taken to eliminate this process, it can completely destroy the station.

To prevent cavitation in the pumps, the rule should be followed: there should be more water at the inlet than at the outlet. This can be achieved in several ways:

move the device a little closer to the source;
you can increase the diameter of the suction pipe (hose);
to reduce the resistance in the suction section, the suction pipe can be replaced with a pipe made of a smoother material;
if there are many turns on the suction pipe, then, if possible, their number should be reduced;
it is desirable that all bends have large turning radii.

Advice! Do not lower the suction hose of the station into the well to a depth of more than 8 meters. Usually maximum depth the immersion of the hose (pipe) is indicated in the manual for the equipment.

How to choose a mechanical water pump
How to care for a mechanical water pump
Why is an electric mechanical water pump better than a mechanical one?

A mechanical water pump is designed to simplify the pouring of water into various containers or to make it more convenient to supply liquid from a well. Today, the market is widely represented by the most different models mechanical water pumps. Everyone will be able to choose for themselves the most suitable model a device that is so necessary in everyday life, taking into account the budget allocated for the purchase. This article will talk about a mechanical water pump in more detail.

The principle of operation of a mechanical pump for bottled water

A mechanical water pump is a device that is installed on the neck of a bottle and helps to quickly and conveniently pour liquid out of it. If necessary, the pump can be easily removed. Application mechanical pump will allow you to easily and simply fill any container by pumping water out of the bottle with light pressure in a dosed manner. This design is especially convenient when using coolers. From a mechanical point of view, the pump is an easy-to-handle water pump that must be carefully maintained and stored under sterile conditions when not in use.

You can buy a mechanical water pump on specialized sites by choosing one of the models in catalogs, as well as in online stores. It is important to keep in mind that before making a purchase, you need to collect as much information as possible about the modification you like, namely: find out the principle of operation, design features, what are the advantages and disadvantages of the device, it is advisable to read the instruction manual.

Differences between pump models may lie in design features or in the principle of operation. The most in demand today are pump electric models that require minimal physical effort and operate from the mains. But also simple manual mechanical water pumps for long years presence in the market have earned the love of consumers. Such models have a small set of functions and require the application of physical effort to obtain a result. At the same time, the undoubted advantage of such devices is their reasonable price.

The design of a mechanical water pump consists of:

pump pump (self-priming mechanism);
two nozzles (suction and supply);
rotating drum;
air filter;
batteries (in electric pumps);
cigarette lighter socket (in electric models);
adapter;
carrying handles (not available on all models).

Advantages of a mechanical water pump:

Top 3 running models of mechanical water pumps

To date, a mechanical water pump is one of the most popular devices designed to simplify the bottling of water from bottles. Among the most popular modifications are the following:

This is the most simple model without a hard case. Such a pump is installed in the hole of the plug, which can not be removed. Water is supplied through a collection pipe. It is advisable to install bottles with similar mechanical water pumps in the country, at home, in offices, in educational and healthcare institutions, and in enterprises. For the production of such models, high-quality food-grade plastic is used, which does not have additives hazardous to health and does not exude unpleasant odors.

This mechanical water pump is equipped with a handle for transporting the bottle. The pump is installed on the neck of the container by means of a retaining ring. Water is supplied through a telescopic tube. It is optimal for use both at home and in various social institutions and enterprises.

The mechanical water pump of this modification is installed on the tank with a swivel nut. Water is also supplied through a telescopic tube. Suitable for use at home, cottages, offices, healthcare facilities and enterprises. Such pumps are made of high quality food grade plastic that does not contain additives hazardous to health and bad smell. The manufacturer gives a 2-year warranty on its pumps, as it is confident in their highest quality.

How to choose and care for a mechanical bottled water pump

When deciding to purchase a mechanical bottled water pump for use in your home or office, it is important to take a closer look at the list of models on the market, which will allow you to find the most suitable option in terms of value for money. We also recommend that you go to the specialized forums and read the reviews of other buyers about these devices. It would be useful to apply for background information to a specialist in filters and pumps.

When choosing a mechanical pump that will constantly interact with drinking liquid, first of all, you need to pay attention to the quality of the device and, especially, the material of manufacture. It is also worth taking care that the selected model has the right amount of performance and relevant parameters for your capacity.

Different models of mechanical pumps have water supply pipes of different lengths, which ensures the use of the device for bottles that differ in volume and depth. A properly selected mechanical pump will allow you to empty the bottle without residue.

On the market, mechanical pumps for bottled water are presented in various color solutions, which can be considered a nice addition to all the advantages of this device. Thus, everyone gets the opportunity to choose a pump that will harmoniously fit into the interior of the room where it is planned to operate it.

In some modifications, it is possible to close the spout cover, which will help to avoid the penetration of dirt and dust inside, and therefore prevent water damage.

If you have not used a mechanical water pump for a long time, then before resuming operation, you need to disassemble the device and thoroughly rinse every part. Care manipulations must be carried out very carefully, since most of the parts are quite fragile, made of plastic.

However, the pump must be flushed even if it is in continuous operation. It is recommended to do this according to the following algorithm:

carefully disassemble the pump into parts;
rinse each part well, remembering that you should not squeeze the elements too much. For washing, it is better to use ordinary water, without resorting to cleaning products;
to eliminate serious contamination, place the pump in hot water(temperature not more than 60 °) for a while (no longer than 15 minutes);
dry the washed structural elements;
assemble the device in reverse order.

Some manufacturers make it easier for their customers to take care of their pumps by selling a special cleaning brush with the device, which allows you to clean the mechanism much faster and better.

Repair of a mechanical pump for bottled water

There are a huge number of pump models: manual, electric, mechanical pumps for water in capacities of 19 liters and 5 liters. In the event of a pump failure, repair will not cause difficulties. To do this, it is enough to understand how it works.

The mechanical pump for water is tightly fixed on the neck of the bottle. By pressing the button with the help of a plastic corrugation, you accumulate air in the container. Gradually, the pressure increases, and the water begins to go up the tubes.

The pump stopped pumping fluid - what to do?

This malfunction can have only one reason: a leak.

How and where to find the problem?

First you need to disassemble the device into parts (see the picture above).
Examine each element in search of defects that have arisen. Corrugation is especially worth studying, since ordinary polyethylene is usually used for its production.
Make sure that all valve petals are in order, since they are responsible for the safety of air in the bottle when the corrugations are straightened after pressing the button.

If the corrugation is found to be damaged, it must be replaced. However, if the hole is small, then it can be sealed with adhesive tape or a plastic adhesive substance. It is recommended to carry out these operations from the inside so that air pressure does not reduce all your work to zero.

In the event that the valve has been torn off, it should be installed in place. This usually happens due to excessively strong and abrupt pressing of the button.

If all of the above manipulations did not help fix the breakdown, you should see if the pump itself is correctly installed on the neck and if the sealing ring is in place. It is important that the pump fits close to the neck, preventing the slightest air leakage.

There are situations when improper removal of the pump (without loosening the clamp) leads to a breakdown rubber seal. This error is immediately noticeable. If you pull the edge of the seal and it will easily give you a meeting, you need to return it to its place and fix it in accordance with the features of the modification. To do this is quite simple: you need to disassemble the holder and install the seal in place.

What is the difference between an electric water pump and a mechanical water pump?

All types of pumps, both mechanical and electric, operate on the principle of a pump. The key difference between the models is that some are powered by hands, while others are powered by mains electricity or batteries.

Device and principle of operation

In order to put into action electric pump for water, two batteries are enough, which are enough to empty 70 bottles. The pump can be started by pressing a button. Having received the desired portion of water, you should once again press the start button to turn off the device. Moreover, the water supply will stop immediately, not a single drop will be spilled in vain.

Some customers do not want to spend money on coolers, plastic or ceramic dispensers, but still need automatic filling, in this case electric pump fits perfectly. An electric pump will satisfy all needs, and the costs will be associated only with the purchase of new batteries.

An electric water pump makes it easy and simple to pour water from a large container. Moreover, this process does not require the slightest effort from a person.

Using an electric water pump, a person can only:

go to the bottle;
lightly press the button;
drink water poured into a glass.

A small minus of the device can only be called the need to periodically change the batteries. However, one pair lasts for a long time, so replacing batteries will not burden you.

Some models are mains powered and do not require batteries. However, the placement of such pumps is limited by proximity to outlets. Moreover, if there are power outages, you will not be able to use the pump to pump water out of the bottle.
Based on this, the best option we can name such water pumps that can work both from the mains and from batteries, and are also equipped with a mechanical pump.

Which water pump is better to choose

Which water pump to buy is up to you. Any of these models is able to meet your needs in full. However, before making a purchase, check the quality of the device. This is important, since the cheapest models can become unusable literally on the very first day of operation. Also, when choosing a pump for water, consider the parameters of the bottle on which you are going to install it. Thus, you can buy a device with a suitable length of the fluid intake tube.

Correction of the simplest problems on the shoulder home master, but you must admit, even elementary repair operations need to be known how to carry out correctly.

We are happy to help you master the difficult work of a repairman. household appliances. In the article brought to your attention, all are described in detail. characteristic species breakdowns of pumping units. Effective methods for eliminating failures in the operation of water supply installations are given.

Those who wish to repair the pumping station with their own hands will find answers to all questions that arise in such cases. Useful information backed up step by step photo instructions, diagrams and videos.

With the help of a pumping station, you can solve several problems related to water supply:

organize the automatic flow of water from the source to the plumbing system of the house;
adjust the water pressure in the water supply, bringing it to an acceptable level;
protect plumbing system from water hammer;
to create some reserve of water in case of problems with water supply.

When troubleshooting a pumping station, it must be remembered that for almost all models of surface pumps, dry-running is categorically not recommended. Before turning on the pump to check its operation, make sure that it is filled with water. If this is not the case, the device must be filled through a special filling hole.

“Dry running”, i.e. work without water, idling, is very dangerous for almost all models of surface pumps. Parts wear out a lot, the motor winding may burn out

#1: Pump is running, no water is flowing

If the pump turns on and you can see (hear) that it is working, but no water enters the tank, you should figure out exactly where this water goes. The first thing to check is . If it got bad, the water just poured back out. If there is water in the intake hose, then the check valve is not to blame for anything, you need to look for another reason.

If the hose is empty, it should be removed and the check valve inspected. It may happen that the pumping station does not pump water at all due to a simple clogging of the valve holes. It is enough to rinse the device so that it starts working correctly again.

Sometimes you need to replace the spring or the entire valve. Of course, after replacing a part or repairing, you should check the operation of individual components of the pumping station, and only then perform final assembly and start up the device.

The check valve is necessary for the normal operation of the pumping station. If its holes are clogged, you just need to disassemble the device and rinse it

If there is water in the intake hose, you need to check all joints and pipes between the pump and the tank for leaks. Perhaps the water simply flows out through a crack or hole. A damaged pipe must be replaced, and a leaky connection must be cleaned, sealed and sealed again.

If the threaded connections of the pumping station become leaky and leak, they must be cleaned and resealed with suitable materials.

There is a third reason why water does not go to the hydraulic tank: the low debit of the water source. This happens if, for some reason, water does not enter the water intake part of the well or well.

This happens, for example, as a result of silting or sanding. Or the pump for the source is chosen incorrectly, it pumps out water too quickly, its reserves do not have time to recover.

How to choose, install and connect for a water intake development is described in the article, which we recommend that you read.

The pump will most likely need to be replaced, there are special models for low flow sources. To increase the flow rate of the well, it makes sense to pump it, i.e. wash away accumulated dirt. To flush the well, a separate pump should be used, and not the one that is equipped with a pumping station.

As an urgent measure, it is sometimes advised to take water from a greater depth, but this recommendation should be used with caution. If the source is sandy, immersing the water intake or submersible pump too deep can lead to contamination of the pumping equipment and its serious damage.

Another one possible reason through which the pump stopped pumping water - impeller wear. In this case, it will rotate idly. You will have to remove the pump, disassemble it, rinse it, replace the impeller, and possibly the pump housing. Sometimes it's easier to put in a new pump.

If the above “diagnoses” are not confirmed, it makes sense to simply check the voltage in the electrical network. If it is too low, the pump will turn on, but will not be able to supply water. It remains to establish a normal power supply so that the pumping equipment functions again in the desired mode.

#2: The device turns on but does not work

This happens with pumps that have not been used for a long time (for example, in winter period). Since the clearance between the impeller and the housing is small, these elements, while stationary, can simply “stick” to each other.

When turned on, the pump will hum properly, but the impeller will remain stationary. In such a situation, the device should be turned off immediately.

The gap between the impellers (impeller) of the pump must be small. If the wheels are worn out, the gap will increase and the performance of the device will decrease, so it is better to replace the wheels with new ones.

To cope with this problem is not difficult, just turn the impeller a couple of times with your hands. If after turning on the pump operation resumed, then the obstacle has been removed.

Of course, before starting operation, a pump that has not been working for some time will not hurt to flush. Sometimes the impeller has nothing to do with it, the capacitor just failed. The damaged item must be replaced.

A burnt condenser is a common cause of breakdowns in a pumping station. It is not difficult to replace it with a new element with suitable characteristics.

#3: The pumping station is jerky

This behavior of technology is most often typical for situations where there are problems with pressure inside the hydraulic tank. First of all, you need to check the behavior of the pressure gauge. If the pump turns off when water enters, as expected, but soon there is a sharp drop internal pressure, problems should be looked for inside.

Most likely, the membrane in the accumulator has torn. It is easy to verify this: if you open the nipple located on the “air” side of the container, water will flow from it, not air.

The hydraulic tank should be dismantled, carefully disassembled, the damaged membrane removed and replaced with a new one, exactly the same. Trying to somehow repair a damaged liner is usually useless, it will quickly deteriorate again.
