When the pressure in the GR reaches 8.5 kgf/cm 2, the pressure regulator opens the access of air from the main reservoir to the cavity above the diaphragm 14 of the unloading devices of the LPC and HPC valve boxes. In this case, the piston 2 will move down. Together with it, after compression of the spring 6, the stop 5 will also go down, which with its fingers will press the small and large valve plates from the suction valve seat. The compressor will go into idle mode, in which the HPC will suck in and compress the air in the refrigerator, and the LPC will suck in air from the atmosphere and push it back through the air filter. This will continue until a pressure of 7.5 kgf / cm 2 is established in the GR, to which the 3RD regulator is adjusted. In this case, the pressure regulator will inform the cavity above the diaphragm 14 with the atmosphere, the spring 6 will lift the stop 5 up and the valve plates will be pressed against the seat with their conical springs. The compressor will go into operating mode.

The KT-6el compressor, when a certain pressure is reached in the GR, is not switched to idle mode, but is turned off by the pressure regulator AK-11B.

During the operation of the compressor, the air between the compression stages is cooled in a radiator-type refrigerator.

The refrigerator consists of an upper 9, two lower collectors 4 and two radiator sections 1 and 3.

The upper collector is divided into three compartments by partitions 11 and 14. The radiator sections are attached to the upper manifold with gaskets. Each section consists of twenty-two copper tubes 8, flared together with brass bushings in two flanges 6 and 10. Brass tapes are wound and soldered on the tubes, forming ribs to increase the heat transfer surface.

To limit the pressure in the refrigerator, a safety valve 13 is installed on the upper manifold, adjusted to a pressure of 4.5 kgf/cm 2 . The flanges of the branch pipes 7 and 15 of the refrigerator are attached to the valve boxes of the first stage of compression, and the flange 12 - to the valve box of the second stage. The lower manifolds are equipped with drain cocks 16 for purging the radiator sections and lower manifolds and removing oil accumulating in them.

1, 3 - radiator sections; 2, 5 - connecting strips, 4 - lower collector; 6, 10, 12 - flanges; 7, 15 - branch pipes, 8 - tubes, 9 - upper manifold; 11, 14 - partitions, 13 - safety valve, 16 - drain cock

The air heated during compression in the LPC enters through the discharge valves into the nozzles 7 and 15 of the refrigerator, and from there - into the extreme compartments of the upper manifold 9. The air from the extreme compartments through 12 tubes of each radiator section enters the lower manifolds, from where through 10 tubes of each section flows into the middle compartment of the upper manifold, from which it passes through the suction valve into the HPC. Passing through the tubes, the air cools, giving off its heat through the walls of the tubes to the outside air.

While in one LPC air is drawn in from the atmosphere, in the second LPC air is pre-compressed and forced into the refrigerator. At the same time, the process of air injection into the GR ends in the HPC.

The refrigerator and cylinders are blown by a fan, which is mounted on a bracket and is driven by a V-belt from a pulley mounted on the compressor drive clutch.

Communication of the internal cavity of the compressor housing with the atmosphere is carried out through a breather, which is designed to eliminate excess air pressure in the crankcase during compressor operation and prevent the release of oil from the crankcase into the atmosphere. The breather consists of a body 1 and two gratings 2, between which a spacer spring 3 is installed and a packing of horsehair or nylon threads is placed. A felt pad 5 with washers 4, 6 and a bushing 7 is placed above the upper grate. A thrust washer 8 and a spring 9 are fixed on the stud 10 with a cotter pin 11.

Compressor lubrication - combined. The pressure generated by the oil pump lubricates the crankshaft journal, the connecting rod pins and the piston pins. The remaining parts are lubricated by spraying oil with counterweights and additional crankshaft balancers. The oil reservoir is the compressor crankcase. Oil is poured into the crankcase through the plug, and its level is measured with an oil gauge. The oil level must be between the marks on the oil gauge. An oil filter is provided in the crankcase to clean the oil entering the oil pump. Pump capacity 5l per minute at 850 shaft revolutions.

The oil pump is driven by the crankshaft, at the end of which is stamped square hole for pressing the bushing and installing the shank of the roller 4 into it. The oil pump consists of a cover 1, a body 2 and a flange 3, which are interconnected by four studs 12 and are centered by two pins 11. The roller 4 has a disk with two grooves into which two blades are inserted 6 with spring 5. Due to the slight eccentricity, a crescent-shaped cavity is formed between the pump housing and the roller disc.

When the crankshaft rotates, the blades 6 are pressed against the walls of the housing by the spring 5 due to centrifugal force. Oil is sucked from the crankcase through port A and enters the pump casing, where it is picked up by the vanes. The compression of the oil occurs due to the reduction of the sickle-shaped cavity during the rotation of the blades. Compressed oil is pumped through channel C to the compressor bearings.

A tube from a pressure gauge is connected to fitting B. To smooth out fluctuations of the arrow of the pressure gauge 16 due to the pulsating oil supply in the pipeline between the pump and the pressure gauge, a fitting with a hole with a diameter of 0.5 mm is placed, a reservoir 17 with a volume of 0.25 l and a disconnecting valve are installed to turn off the pressure gauge.

The pressure reducing valve screwed into cover 1 serves to regulate the oil supply to the connecting rod mechanism of the compressor depending on the crankshaft speed, as well as to drain excess oil into the crankcase.

The pressure reducing valve consists of a body 7, in which the ball valve 8 itself, a spring 9 and an adjusting screw 10 with a lock nut and a safety cap are placed.

As the crankshaft speed increases, the force with which the valve is pressed against the seat under the action of centrifugal forces increases and, therefore, more oil pressure is required to open the valve 8.

At a crankshaft speed of 400 rpm, the oil pressure must be at least 1.5 kgf / cm 2.

There are no unloaders in the valve boxes of the KT-6el compressor, since this compressor is not put into idle mode, but stops. On this compressor, a tank is also not needed to dampen the pulsations of the oil pressure gauge needle, since relatively low frequency rotation of the crankshaft of the compressor and the oil pump roller do not give a noticeable pulsation of the arrow, and the vibration of the compressor at this shaft speed is practically absent.

The compressor operation scheme is divided into three cycles: suction, first compression stage, second compression stage.

suction into the HPC and LPC (left), injection from the HPC,

injection from LPC (right) compression into LPC (right)

When the compressor crankshaft rotates, alternating processes occur in the LPC cylinders: if air is compressed and injected in the left cylinder, then air is sucked in in the right cylinder. Then the right cylinder of the low pressure cylinder goes to the injection, and the left cylinder to the suction, and so on.

Cylinders of low-pressure cylinders alternately push compressed air into the refrigerator. In the refrigerator, air passes through the section tubes to the air intake flange into the high pressure cylinder. One half of the radiator is connected to the left cylinder, the other half to the right cylinder. The valves in the cylinders are controlled by differential pressure. With the suction stroke of each piston, a vacuum is created in the cylinders of the LPC (-0.15 ÷ 0.2 kgf / cm 2) and the valve plates (external and internal) compress the springs with atmospheric pressure and wring out from the annular polished seats and atmospheric air fills the cylinder. After a change in the piston stroke, pressure appears in the cylinder, so the suction valves are pressed against the annular seats by the force of the springs and air pressure from the cylinder, i.e. they close.

With a further stroke of the piston, the pressure of the compressed air in the cylinder of the LPC rises (2.5-4.0 kgf / cm 2) and when it exceeds the pressure of the residual air in the refrigerator, the pressure valve plates, external and internal, compress the springs (three springs for each plate) and each plate is retracted from the round saddles. Air is forced (pushed out) from the cylinder into the refrigerator.

In the high-pressure cylinder, during the injection stroke of the piston, the air above the piston head is compressed and when it exceeds the air pressure of the main reservoir, the plate springs are compressed and the plates are removed from the round annular seats upwards, passing air from the HPC cylinder to the main reservoir. Air is forced into the main tank.

After a change in the piston stroke, the pressure above it drops and the discharge valve plates close. When closed, the discharge valve plates are held by springs and compressed air pressure from above from the main reservoir.

As the piston moves further down towards the bottom dead center, the pressure in the HPC cylinder above the piston decreases from the air pressure in the main reservoir to the air pressure in the refrigerator, and as the HPC piston further lowers, the pressure above it becomes less than the air pressure in the refrigerator. This causes air to be pressed from above the plates of the suction valve and the air to enter from the refrigerator into the HPC cylinder as the piston lowers to the bottom dead center, at which the increase in cylinder volume stops. After the HPC cylinder is filled with air from the refrigerator, the pressure drop on the suction valve plates disappears, so the plates are pressed against the annular seats by the force of conical springs, rising up.

Further, at bottom dead center, the piston stroke reverses. The volume of the cylinder is reduced by the HPC piston and the air coming from the refrigerator in the HPC cylinder is compressed. The pressure above the piston rises to the value of the air pressure in the main reservoir, and then more, which causes the pressure valve plates to be pressed from the seats and the compressed air to pass from the HPC cylinder to the main reservoir.

Compressor K-2

Compressors are vertical, two-stage, three-cylinder, piston with W-shaped arrangement of cylinders, combined lubrication system. Productivity of the K-2 compressor - 2,63m 3 at 720 revolutions per minute.

The compressor consists of a housing 22, two cylinders 9 low pressure and one 12 high pressure. On the top of the body there are three flanges for mounting cylinders and one for breather 16, two on the sides for mounting covers on the side of the electric motor and on the side of the oil pump, one on the bottom for mounting an oil bath 24 containing 4.5 liters of oil

1, 2 - intermediate gears, 3 - drive gear, 4 - crankshaft, 5 - bearing, 6 - oil seal, 7 - pump housing, 8 - pump cover, 9 - low pressure cylinder, 10 - low pressure cylinder piston; 11, 14 - valve boxes, 12 - high pressure cylinder, 13 - high pressure cylinder piston, 15 - discharge valve, 16 - breather, 17 - suction valve, 18 - connecting rod pin, 19 - connecting rod, 20 - counterweight, 21 - bolt, 22 - crankcase, 23 - connecting rod cap, 24 - oil bath, 25 - filter

For better heat transfer, the outer surfaces of the cylinders are equipped with annular ribs. Valve boxes 11 and 14 are attached to the flanges of the cylinders, in which there is one suction valve 17 and one discharge valve 15 each.

Valves consist of round metal plates pressed against the seat by springs. The suction valve opens inside the cylinder, the discharge valve opens outward. The valve boxes are separated by a blank partition into two cavities - suction and discharge.

Breather 16 supports in crankcase Atmosphere pressure and prevents oil spill.

The crankshaft 4 is made of manganese-chromium steel and is equipped with counterweights 20 attached to the cheeks with studs.

The upper heads of the connecting rods 19 are one-piece with bronze bushings, and the lower ones are split with a cover 23 and bronze liners filled with babbitt. The covers are attached to the connecting rods with bolts 21.

The pistons 10 and 13, connected to the connecting rods by means of pins 18, are cast from an aluminum alloy. The pistons are fitted with three compression rings and two oil scraper rings.

To eliminate oil leakage, shaft 4 is sealed at both ends with oil seals, consisting of a rubber cuff with a metal spacer ring. Support double-row roller bearings 5 ​​of the crankshaft are placed in the covers.

The housing 7 of the gear-type oil pump with an intermediate flange and a cover 8 is attached to the rear bearing cover. The drive gear 3 is located on the crankshaft of the compressor, and the drive gear, together with the intermediate gear, is located on the pump shaft. The oil from the bath enters the gear pump through the pipe and through the annular groove and drilling in the body of the crankshaft gets to the connecting rod bearings, as well as to the pressure reducing valve, which limits the pressure of the oil supplied by the pump. The shank of the crankshaft is closed with a cover. 4.5 liters of oil are poured into the crankcase.

Compressor lubrication combined: cylinders, piston rings and roller bearings are lubricated with oil sprayed by the rotating parts of the compressor; piston pins, connecting rod bearings and crankshaft journals - forcibly under pressure created by the oil pump. The oil pressure of a working compressor is 2.5-3.5 kgf / cm 2. If this pressure is exceeded, the pressure reducing valve is activated, dumping part of the oil into the crankcase.

In winter, the oil in the compressor is heated by an electric heater powered by the locomotive's battery. Oil is drained from the bath and the radiator housing through holes closed with plugs.

Compressor PK-5.25

Compressor PK-5.25 vertical, two-stage, six-cylinder, piston with a V-shaped arrangement of cylinders, with air cooling and intermediate cooling of compressed air in a tubular cooler, combined lubrication system. Productivity of the compressor PK 5.25 - 5,25m 3 /min at 1450 rpm.

The cast-iron casing 4 of the compressor serves to fasten components and parts on it and at the same time is a crankcase, the front part of the casing is closed by a cover 18, in which one of the three crankshaft bearings is installed. On the side surfaces of the housing there are four hatches for access to parts located inside the crankcase, and a tide for probe 3.

An oil filter 11 and an electric heater 12 are located at the bottom of the crankcase.

Six cast-iron cylinders are attached to the body on studs: three low-pressure cylinders 9 and three high-pressure cylinders 2. All cylinders have fins to improve heat transfer. The internal cavity of the housing communicates with the atmosphere through the breather 8, similar in design to the compressor breather KT-6, but having a smaller size.

The steel crankshaft 14 has three crankpins with counterweights and rotates on three ball bearings. There are two connecting rods on each crankpin. A sleeve with a square hole is pressed into the end of the crankshaft for installing the oil pump drive. The body of the crankshaft has holes for supplying oil to the connecting rod bearings.

The pistons of the low pressure cylinder are made of aluminum alloy, and the pistons of the high pressure cylinder are made of cast iron. Each piston has two compression rings and two oil scraper rings.

Valve boxes 7 of the first stage and valve boxes 1 of the second stage are attached to the upper flanges of the cylinders on studs, in which the suction and discharge valves are located. Each valve box is divided by a partition into suction and discharge cavities.

The valve consists of two plates 5 and 2 and two groups of self-springing valve plates 3. The plates are connected to each other with a screw 6 and secured with a nut 7. Keys 4 protect the plates from longitudinal shift. Each of the plates simultaneously serves as a saddle for one group of plates, and as a lift limiter for the other. Thus, one pair of valve plate assemblies combines the suction and discharge valves of the same cylinder.

1 - body; 2, 5 - valve plates, 3 - valve plates, 4 - key, 6 - screw

When the piston moves down, the plates of the suction valve are bent along the arc of the recesses (nests) in the bottom plate 5, which in this moment are lift limiters (valve stroke), and the discharge valve plates are pressed against the bottom plate 5, which in this case is a seat for them. When the piston moves upwards, the suction valve plates are pressed against the upper plate 2, which in this case serves as a seat, and the discharge valve plates bend along the arc of the recesses (slots) in the upper plate 2, which at this moment are the lift limiters (valve stroke).

In each LPC valve box there are 10 suction and discharge plates, and in the HP valve box there are 4 suction and discharge plates.

The air sucked in by the compressor is cleaned in the air filters 10 connected to the valve boxes 7 of the LPC. Between the compression stages, the air is cooled in an intermediate cooler 6 with a safety valve 5 adjusted to a pressure of 3.5 kgf/cm 2 .

The refrigerator, valve boxes and cylinders are blown by the fan 15, which is mounted on the rack 16 and is driven from the crankshaft through the V-belt transmission 17.

Lubrication is supplied by oil pump 13, which is similar in design to the oil pump of the KT-6 compressor, only the pump housing, blades and drive roller disks are narrower in order to provide the necessary pump performance at a crankshaft speed of 1450 rpm. Excess oil is discharged through the pressure reducing valve into the compressor crankcase.

Compressors PK-5.25 are equipped with a drive sleeve-pin coupling. Between the leading 21 and driven 20 half-couplings connected by fingers 19, a gap is provided to ensure the replacement of the V-belt 17 of the fan without disturbing the installation of the compressor or engine.

PC type compressors are not equipped with unloaders for switching to idle mode. To ensure the operation of compressors on diesel locomotives driven by a diesel engine, idle valves are provided.

The device provides communication of the pressure line of the compressor with the main tanks in the operating mode and with the atmosphere in the idle mode.

The control valve is assembled in housing 2, the idle valve is in housing 1, the check valve is in housing 6.

When the idle valve 4 is closed, the compressed air from the compressor through the check valve 5 enters the GR. The cavity under the piston 3 is connected with the atmosphere through the lower channel 8 in the body 2. When the pressure in the GR is reached, to which the spring 7 is adjusted, the piston 9 moves to the right, separating the cavity under the piston 3 from the atmosphere and communicating it with the GR through the upper channel 8. The piston 3 moves up and opens the idle valve 4, as a result of which the air from the compressor escapes into the atmosphere. At the same time, the check valve 5 closes with its spring and blocks the air outlet to the atmosphere from the GR.

When the pressure in the GR is reduced to a certain value, the piston 9 of the control valve returns to its original position by spring 7, communicating the cavity under the piston 3 with the atmosphere through the lower channel 8 in the housing 2. In this case, the idle valve 4 is pressed against the seat by its spring, and the compressed air from compressor through the check valve 5 begins to flow into the GR.

The pressure difference between the working and idling compressor is provided by changing the tightening of the adjusting spring 7.

EK-7B compressors are horizontal, piston, single-stage, two-cylinder, splash lubrication system. The productivity of the compressor EK-7B is 0.58 m 3 /min at 540 rpm.

The compressor consists of the following main components: housing 1, crankshaft 5, cylinder block 13, connecting rod and piston group 7, 19, valve cover 17 with suction 15 and discharge cavities 16, motor shaft 23 and two-stage gear reducer 2.

The cast-iron compressor housing has two cavities: a two-stage gearbox is located in the left cavity, and a crankshaft is located in the right cavity.

The compressor housing is the main base part on which all other components and parts are mounted. Access to the housing is through windows closed by covers.

The double-crank crankshaft rests on two radial single-row ball bearings 9, one of which is mounted in the horizontal bore of the end wall of the housing, and the other in the front bearing cover 20. Two horizontal connecting rods 7 are mounted on the connecting rod journals of the crankshaft. Their lower heads are filled with babbitt and form connecting rod bearings with bolts; bronze bushings for piston pins 18 are pressed into the upper heads. On both covers 6 of the connecting rods, one oil sprayer 8 is provided, which is mounted in the connecting rod connector.

1 - housing, 2 - gear block, 3 - eccentric shaft, 4 - drain plug, 5 - crankshaft; 6, 10, 17 - covers, 7 - connecting rod, 8 - sprinkler; 9, 20 - bearings, 11 - oil scraper rings, 12 - compression rings, 13 - cylinder block, 14 - plate, 15 - suction cavity, 16 - discharge cavity, 18 - piston pin, 19 - piston; 21, 22 - gears, 23 - electric motor, 24 - belt valves

Pistons 19 are made of gray cast iron. There are three streams on each piston head: two upper ones - for sealing rings 12 and one lower one - for oil scraper ring 11; on the skirts of the pistons there are streams for the second oil scraper rings. The sealing piston rings are tapered to reduce the emission of oil into the line and speed up the running-in process. The installation of such a ring is carried out with an end face of a smaller diameter, on which the “top” mark is applied, to the piston bottom.

The cylinder block 13 is made of gray cast iron. The outer surface of the block is ribbed to provide the necessary heat transfer.

Suction and discharge valves are located in one block under cover 17 and are made in the form of a self-springing, tape design. Each of the valves has twelve plates 24: six discharge and six suction, located between the plates 14. The valve cover 17, made of gray cast iron, is attached through a gasket. The outer surface of the lid is ribbed. Inside the cover there is a partition separating the suction cavity 15 from the discharge cavity 16.

Two-stage gearbox 2 is designed to reduce the speed of rotation from the electric motor 23 to the compressor. The gearbox consists of a gear sitting on the shaft 23 of the electric motor, a gear located on the crankshaft 5 of the compressor and a block of two gears rotating on the eccentric axis 3.

The possibility of adjusting the gearing when the teeth are worn is ensured by the fact that the axis can occupy five different positions; for this, there are five holes on one of the bearing journals. The axis is fixed in any position by a screw. To improve lubrication conditions, the eccentric axle is made hollow inside with four through oil channels.

The gearbox gears are partially immersed in oil and lubricate the entire gearbox. When the crankshaft rotates, oil from the crankcase is captured by oil sprinklers 8 mounted on the connecting rods. This creates an oil mist that settles on the working surfaces of the rubbing parts and lubricates them. The compressor housing is filled with oil up to the upper level of the oil filler hole. The oil level is controlled by an oil dipstick, which has a risk. An oil level below this mark is not allowed. An oil baffle washer is installed on the motor shaft.

Compressor EK7V single-stage compression: suction and compression of air occur in one cylinder in two piston strokes. When the pistons move, suction occurs in one of the cylinders, and injection occurs in the other. For one revolution of the crankshaft, each cylinder completes one complete cycle of suction and discharge. When the piston draws in air, the suction valve of that cylinder opens and the discharge valve closes.

Safety valves

Safety valves release compressed air in the event of an increase in pressure to a level dangerous for the strength of the GR in the event of a regulator malfunction.

Safety valves No. 216 and No. E-216 are structurally identical and differ only in the number of atmospheric holes Am in the body and the size of the springs. Valves No. 216 are installed between the first and second stages of compression of locomotive compressors and are regulated to a response pressure of 3.5-4.5 kgf / cm 2, valves No. E-216 are installed on the discharge pipeline or on the main tanks and are regulated to operate at a pressure exceeding the operating pressure 1.0kgf/cm2.

The safety valve No. E-216 has a body 4 with atmospheric openings At, onto which a fitting 1 is screwed. In the fitting there is a poppet stall valve 2 with guide ribs. The valve 2 has two pressure areas: the working (small) surface up to the lapping ring and the shedding (large) surface up to the outer circumference of the valve. Valve 2 is loaded by spring 3, the force of which is regulated by nut 5, closed by cap 6. Holes but in the cap and in the body are used to install the seal.

The force of the spring 3 presses the valve 2 to its seat, and the compressed air pressure acts from below on the working area of ​​the valve. As soon as the air pressure exceeds the force of the spring, the valve 2 will slightly move away from the seat, after which the air will already act on the stall (large) area of ​​the valve. The pressure force on the valve from below increases sharply and it quickly rises, releasing air into the atmosphere through the holes Am in the body. The outflow of air will continue until the force of the spring exceeds the force of air pressure on the stall area of ​​the valve 2. After landing on the seat, the valve will be securely held by the spring in the closed position, since the air pressure will be distributed to the working (small) area of ​​the valve.

Safety valve No. 216 Safety valve M

1 - fitting, 2 - valve, 3 - spring, 1 - housing, 2 - spring, 3 - valve,

4 - body, 5 - adjusting nut, 6 - cap 4 - cone screw, 5 - adjusting screw

Safety valves M installed on locomotives of Czech production. The valve has a body 1, in which a stall valve 3 of the cup type is located loaded with a spring 2. The required spring force is provided by adjusting screw 5. Valve 3 has a working (small) area of ​​compressed air impact equal to the diameter of the valve seat in the body, and a stall (large) area equal to the diameter of valve 3.

When the force of compressed air pressure on the valve from below overcomes the force of the spring, the valve rises. In this case, air will be released into the atmosphere through the holes At in the housing 1. At the same time, air through the hole but in valve 3 will pass into the cavity above it and exit to the atmosphere through the hole b, the cross section of which can be adjusted with a cone screw 4. The moment of valve 3 refitting on the seat under the action of a spring depends on the ratio of the cross sections of the holes but And b and the pressure in the cavity above the valve. Thus, changing the cross section of the hole b, you can adjust the pressure difference between the valve lift and seat. The smaller the opening will be b, the lower the pressure difference will seat on the valve seat 3.

Inspection and verification of the load adjustment of safety valves is carried out at least 1 time in 3 months and at the current TP-3 and overhauls locomotives. If the timing of the periodic inspection and testing of safety valves does not coincide with the setting of the rolling stock for the next scheduled repair, it is allowed to increase the operation of the safety valves up to 10 days in excess of the established period.

check valves

Check valves are used to pass compressed air in one direction only.

Rice. 5.2 Compressor device.

Compressor KT-6 Fig.5.2 consists of a housing (crankcase) 13, two low-pressure cylinders 29 (LPC), having a camber angle of 120°. one high-pressure cylinder 6 (HPC) and a radiator-type refrigerator 8 with a safety valve 10, a connecting rod assembly 7 and pistons 2, 5. The body 18 has three mounting flanges for installing cylinders and two hatches for access to parts inside. An oil pump 20 with a pressure reducing valve 21 is attached to the side of the housing, and a mesh oil filter 25 is placed in the lower part of the housing. housing on the oil pump side.

All three cylinders have ribs: the HPC is made with horizontal fins for better heat transfer, and the LPC has vertical ribs to make the cylinders more rigid. Valve boxes 1 and 4 are located in the upper part of the cylinders. The crankshaft 19 of the compressor is steel, stamped with two counterweights, has two main journals and one connecting rod. To reduce the amplitude of natural vibrations, additional balancers 22 are attached to the counterweights with screws 23. To supply oil to the connecting rod bearings, the crankshaft is equipped with a system of channels.

Rice. 5.3 Connecting rod assembly.

The connecting rod assembly Fig.5.3 consists of the main 1 and two trailed 5 connecting rods, connected by pins 14, locked with screws 13.

1 - main connecting rod, 2, 14 - pins, 3, 10 - pins, 4 - head, 5 - trailer connecting rods, 6 - bronze bushing, 7 - stud, 8 - lock washer, 9 - lubrication channels, 11, 12 - liners, 13 - locking screw, 15 - removable cover, 16 - gasket

The main connecting rod is made of two parts - the connecting rod itself 1 and the split head 4, rigidly interconnected by a pin 2 with a pin 3 and a pin 14. Bronze bushings 6 are pressed into the upper heads of the connecting rods. The removable cover 15 is attached to the head 4 with four studs 7, the nuts of which are locked with a lock washer 8. In the bore of the head 4 of the main connecting rod, two steel inserts 11 and 12 are installed, filled with babbitt. The liners are held in the head due to tension and locking with pin 10. The gap between the shaft neck and the connecting rod bearing is regulated by gaskets 16. Channels 9 serve to supply lubricant to the upper heads of the connecting rods and to the piston pins.

The main advantage of this system of connecting rods is a significant reduction in wear of the liners and the connecting rod journal of the crankshaft, which is ensured by the transfer of forces from the pistons through the head to the entire surface of the neck at once. Pistons 2 and 5 (Fig.5.2.) - cast iron. They are attached to the upper ends of the connecting rods with 30 floating type piston pins. To prevent axial movement of the fingers, the pistons are equipped with retaining rings. The piston pins of the LPC are steel, hollow, the piston pins of the HPC are solid. Four piston rings are installed on each piston: two upper ones are compression (sealing), two lower ones are oil scraper. The rings have radial grooves for the passage of oil removed from the cylinder mirror. The valve boxes are divided by an internal partition into two cavities: suction (B) and discharge (H). (Fig.5.3).

Rice. 5.3. KT-6 compressor valve box.

1 - locknut, 2 - screw, 3, 15 - covers, 4 - discharge valve, 5, 9 - stops, 6 - housing, 7, 18 - gaskets, 8 - suction valve, 10, 12 - springs, 11 - rod, 13 - piston, 14 - rubber diaphragm, 16 - glass, 17 - asbestos cord B - suction cavity, H - discharge cavity

In the LPC valve box, a suction air filter 9 is attached to the side of the suction cavity (Fig. 5.2.), and a refrigerator 8 is attached to the side of the discharge cavity. discharge valve 4 is placed in the discharge cavity, which is pressed against the socket in the body with the help of stop 5 and screw 2 with locknut 1. Suction valve 8 is located in the suction cavity. Cover 3 and valve seats are sealed with gaskets 18 and 7, and the cup flange 16 is sealed with asbestos cord 17.

Rice. 5.4. Suction (a) and discharge (b) valves.

Suction and discharge valves (Fig.5.4) consist of a seat 1, a clip (stop) 5, a large valve plate 2, a small valve plate 3, conical band springs 4, a stud 7 and a castle nut 6. Saddles 1 have two rows around the circumference windows for air passage. The normal stroke of the valve plates is 1.5 - 2.7 mm. The KT-6 El compressor, when a certain pressure is reached in the GR, is turned off by the pressure regulator. During the operation of the compressor, the air between the compression stages is cooled in a radiator-type cooler (Fig.5.5.).

Fig.5.5. Radiator refrigerator.

The refrigerator consists of an upper 9 and two lower collectors and two radiator sections 1 and 3. The upper collector is divided into three compartments by partitions 11 and 14. The radiator sections are attached to the upper manifold with gaskets. Each section consists of 22 copper tubes 8, flared together with brass bushings in two flanges 6 and 10. Brass tapes are wound and soldered on the tubes, forming ribs to increase the heat transfer surface. To limit the pressure in the refrigerator, a safety valve 13 is installed on the upper manifold, adjusted to a pressure of 4.5 kgf/cm2.

The flanges of the branch pipes 7 and 15 of the refrigerator are attached to the valve boxes of the first stage of compression, and the flange 12 - to the valve box of the second stage. The lower manifolds are equipped with drain cocks 16 to purge the radiator sections and lower manifolds and remove oil and moisture accumulating in them. The air heated during compression in the LPC enters through the discharge valves into the nozzles 7 and 15 of the refrigerator, and from there - into the extreme compartments of the upper manifold 9. The air from the extreme compartments through 12 tubes of each radiator section enters the lower manifolds, from where through 10 tubes of each section flows into the middle compartment of the upper manifold, from which it passes through the suction valve into the HPC.

Passing through the tubes, the air cools, giving off its heat through the walls of the tubes to the outside air. While in one LPC air is drawn in from the atmosphere, in the second LPC air is pre-compressed and forced into the refrigerator. At the same time, the process of air injection into the GR ends in the HPC. The refrigerator and cylinders are blown by fan 14 (Fig. 3.2.), which is mounted on bracket 12 and is driven by a V-belt from a pulley mounted on the compressor drive clutch. The belt tension is carried out by bolt 13.

The communication of the internal cavity of the compressor housing with the atmosphere is carried out through breather 3 (Fig. 5.2.), which is designed to eliminate excess air pressure in the crankcase during compressor operation.

Rice. 5.6. Breather.

The breather (Fig. 5.6) consists of a housing 1 and two gratings 2, between which a spacer spring 3 is installed and a packing of horsehair or kapron threads is placed. A felt pad 4 with washers 5, 6 and a bushing 7 is placed above the upper grate. A thrust washer 8 of the spring 9 is fixed on the stud 10 with a cotter pin 11. When the pressure in the compressor crankcase increases, for example, due to the passage of air by compression rings, the air passes through the breather packing layer and moves up the felt pad 4 with washers 5 and 6 and bushing 7. The spring 9 at the same time the compressor crankcase goes into the atmosphere. When a vacuum appears in the crankcase, the spring 9 ensures that the gasket 4 moves down, preventing air from entering the crankcase from the atmosphere.

Compressor lubrication - combined. Under the pressure created by the oil pump 20 (Fig. 5.2), the connecting rod journal of the crankshaft, the pins of the trailed connecting rods and the piston pins are lubricated. The remaining parts are lubricated by spraying oil with counterweights and additional crankshaft balancers. The oil reservoir is the compressor crankcase. Oil is poured into the crankcase through plug 27, and its level is measured with an oil gauge (dipstick) 26. The oil level should be between the risks of the oil gauge. To clean the oil supplied to the oil pump, an oil filter 25 is provided in the crankcase.

rice. 5.7. Oil pump.

The oil pump (Fig.5.7.) is driven by the crankshaft, at the end of which a square hole is stamped for pressing the bushing and installing the shaft shank 4 into it. The oil pump consists of a cover 1, a housing 2 and a flange 3, which are interconnected by four pins 12 and centered with two pins 11. Roller 4 has a disk with two grooves into which two blades 6 with a spring 5 are inserted. Due to a slight eccentricity, a sickle-shaped cavity is formed between the pump housing and the roller disk.

When the crankshaft rotates, the blades 6 are pressed against the walls of the housing by the spring 5 due to centrifugal force. The oil is sucked from the crankcase through port "A" and enters the pump court, where it is picked up by the vanes. The compression of the oil occurs due to the reduction of the sickle-shaped cavity during the rotation of the blades. Compressed oil is pumped through channel "C" to the compressor bearings. A tube from a pressure gauge is connected to fitting "B". There is a disconnect valve to turn off the pressure gauge. The pressure reducing valve (Fig. 5.7), screwed into cover 1, serves to regulate the oil supply to the compressor connecting rod mechanism depending on the crankshaft speed, as well as to drain excess oil in the crankcase.

The pressure reducing valve consists of a body 7, in which the ball valve 8 itself, a spring 9 and an adjusting screw 10 with a lock nut and a safety cap are placed. As the crankshaft speed increases, the force with which the valve is pressed against the seat under the action of centrifugal forces increases and, therefore, more oil pressure is required to open the valve 8. At a crankshaft speed of 400 rpm, the oil pressure must be at least 1.5 kgf/cm2.

Compressor KT-6 is designed to provide locomotives necessary volume compressed air. It is important for powering brake, pneumatic and other rolling stock systems. The device is powered by a diesel engine. The model powered by an electric motor is called KT-6El.

The difference between the models KT-6 and KT-7 of compressor stations is only in the opposite directions of rotation of the crankshaft and the oil pump. Due to this difference, each model is used for certain types of locomotives.

Each compressor has its own performance indicators. It's performance and efficiency. The performance of the apparatus shows exactly what amount of compressed air with the help of the injection force passes in a certain unit of time. Productivity is determined by the time of pressure increase.

The efficiency for a compressor plant is divided into three categories. These are isothermal, mechanical and volumetric efficiency. Isothermal efficiency evaluates the perfection of the compressor, mechanical - takes into account the friction of parts and the operation of additional mechanisms, namely a fan and an oil pump. The volumetric efficiency characterizes the ratio between the discharge and suction pressures in the instrument housing. The ratio of the required characteristics will help you choose the perfect compressor for any type of locomotive.

Compressor device

The casing of the KT 6 compressor is made of cast iron, which significantly increases its degree of reliability and protection. The housing contains 2 low pressure cylinders and 1 high pressure cylinder, cooler, fan and oil pump. It also has an air collector, heat exchanger, idle speed controller and safety valves in CT-6. The body itself is attached directly to the frame of the locomotive using 4 special paws.

The working cylinders are located at a certain angle, thus forming a W-shaped position. It is she who provides high performance device pressure.

The design of the KT 6 compressor ensures operability when the following conditions are met:

• ambient temperature from -55 to +65 C
• compressor installation height does not exceed 1200 m above sea level

KT 6 compressors are three-cylinder two-stage piston units, equipped with air cooling. The KT 6 compressor housing is made of cast iron with four mounting feet for mounting the compressor.
Maintenance of KT-6 compressors is one of the activities of the company "Melcom-Trading"

The essence of the compressor

The operation of the compressor station is as follows: a diesel-powered engine sucks air through the air filter, then it is compressed by low and high pressure cylinders alternately with cooling through a heat exchanger. Compressed air enters the air collector and is sent further for its intended purpose.

There are two stages of air compression in the compressor. Air intake takes place directly in the right low pressure cylinder. After that, there is 1 stage of compression in the left LPC. Then the forced air is sent to the refrigerator through a special valve. The piston of the high-pressure cylinder, when moving downwards, helps to suck air from the refrigerator. Injection and compression occurs due to the return valves in KT-6.

When the pressure rises above the established norm, the air immediately enters the unloading devices of the cylinders. In this case, the valve plates are automatically squeezed out, the work goes to idle. It is necessary to lower the working pressure. When the equipment parameters are normalized, compressed air again begins to flow into the air intake valve in KT-6. Safety valves are provided to prevent any accidents or breakdowns.

Compressor Maintenance
