The booster pump is a component which is beneficial to improving and stabilizing the performance of the automobile, mainly assists a driver to adjust the direction of the automobile, and at present, the booster pump is arranged on an automobile, a truck or a bus.

The space of installing the air compressor and the booster pump is reduced day by day because a large number of cabin bodies are needed by the batteries of new energy passenger cars and electric cars, the air compressor and the booster pump are arranged in a certain space, a controller and a high-voltage wire harness are needed, the arrangement is difficult, and later maintenance, overhaul and the like can not be smoothly carried out due to the compact arrangement. And the space of the cabin is small, so that the air compressor is easy to be heated until the air compressor is stopped. In order to adapt to the high-temperature environment of a compact and closed cabin, the air-cooled air compressor has to increase the heat dissipation capacity, and the noise is increased as a side effect.

The compressed gas of the air compressor can generate a large amount of heat, and a cooling system is required to be used for cooling. The sliding vane type air compressor needs lubricating oil for lubrication, so when the oil temperature is not high, heat is taken away from the stator and rotor cavities through small circulation of an oil way, and the heat is retained in the lubricating oil, and the specific process is that the lubricating oil in the oil cavity of the oil storage shell is sucked into the stator and rotor cavities through the oil suction ports of the stator and rotor, and then the lubricating oil is sprayed into the oil storage shell for circulation along with compressed air from the stator and rotor cavities; the temperature of the lubricating oil can continuously rise along with the continuous small circulation of the lubricating oil, the temperature of the lubricating oil is usually set to 88 ℃ after the oil temperature rises to a certain value, the oil circuit is opened for large circulation, the lubricating oil is cooled through the cooler, the specific process is that the temperature control valve blocks a passage between an oil suction port of the stator and the rotor and an oil storage shell after reaching the set temperature, the lubricating oil of the oil storage shell enters the cooler through an oil inlet of the cooler, and then enters the oil storage shell through an oil outlet of the cooler to complete the circulation.

The air compressor temperature control valve for controlling the oil circuit size circulation is a key part for maintaining the air compressor, and once a problem occurs, the whole sliding vane type air compressor may be damaged. Therefore, the temperature control valve is required to be maintained every year when the sliding vane type air compressor is maintained, the temperature control valve core is an important part in a temperature control valve assembly and is generally a cylinder, and wax in the temperature control valve core pushes a push rod to realize corresponding action of the temperature control valve by means of expansion with heat and contraction with cold. The temperature control valve core of the air compressor needs to be replaced every year. Present temperature-sensing valve assembly is set up within the oil storage shell, therefore need the oil storage shell to pull down when changing the temperature control case, need break up whole air compressor machine promptly, later maintain the change operation again, the convenience of operatable is very poor to the precision of secondary assembly is difficult to guarantee, makes to dismantle air compressor machine performance such as tolerance, noise to the complete machine after the temperature control case produce the influence of can not a little.

As shown in fig. 1-5, the utility model discloses an external two source water-cooling sliding vane air compressor of temperature-sensing valve, including booster pump 1, motor 2, bell jar 3, compressed air portion 4, cooler 5, valve piece 6, base 7, clutch 8 and temperature-sensing valve, motor 2 and compressed air portion 4 are all fixed on base 7, booster pump 1, motor 2, clutch 8, compressed air portion 4, valve piece 6 and cooler 5 connect gradually.

The bell jar 3 is fixed between the motor 2 and the compressed air part 4, the clutch 8 is positioned in the bell jar 3, the booster pump 1 is positioned at one side of the motor 2, and the compressed air part 4 is positioned at the other side of the motor 2. The motor shaft of the motor 2 penetrates through the left side and the right side of the motor 2, the booster pump 1 is fixedly connected with the motor 2, and the booster pump shaft of the booster pump 1 is connected with the right end of the motor shaft through a coupler.

The valve block 6 is located at the lower part of the compressed air part 4, and the cooler 5 is connected and communicated with a cooling pipeline of the compressed air part 4 through the valve block 6.

As shown in fig. 2, the clutch 8 is an electromagnetic clutch, and the left end of the rotating shaft of the motor is connected to or separated from the rotating shaft of the compressed air unit 4 through the electromagnetic clutch.

The cooler 5 is a plate cooler, but also a water cooler.

As shown in fig. 3, the inlet and outlet of the water cooler are located at the left and right ends of the compressed air part 4, respectively.

As shown in fig. 4 and 5, the temperature control valve includes a valve body assembly and a valve core assembly.

The valve body assembly comprises an oil shell through hole 9-9 penetrating through the outer wall of the oil storage shell 9-1, a screw plug 9-4 connected with the outer end of the oil shell through hole 9-9 and a combined gasket 9-5 arranged between the outer end of the oil shell through hole 9-9 and the screw plug 9-4, and the oil shell through hole 9-9 is communicated with an oil cavity 9-2 and a stator-rotor oil suction port 9-12. The valve core assembly is arranged in the oil shell through hole 9-9 and controls the opening and closing between the oil cavity 9-2 and the stator and rotor oil suction ports 9-12.

The valve core assembly comprises a temperature control valve sleeve 9-6, a temperature control valve core 9-7, a temperature control valve piston 9-8 and a temperature control valve spring 9-10, and a side opening 9-3 communicated with the oil cavity 9-2 is formed in the side wall of the oil shell through hole 9-9; the temperature control valve core 9-7 is contacted with oil in the oil cavity 9-2 through the side opening 9-3. Compared with other schemes that the temperature control valve core 9-7 is in contact with oil through a complex passage, even is not in direct contact with the oil and is only in indirect contact with the oil through other heat conduction parts, the scheme that the temperature control valve core 9-7 is in direct and close contact with the oil has the characteristic that the temperature of the oil is directly and rapidly reacted by the temperature control valve core 9-7, the situation that the oil in the oil storage shell 9-1 actually reaches the set temperature, but the oil flows to the temperature control valve core 9-7 through the complex passage to be cooled, or the opening of the temperature control valve core is delayed from the actual working condition through heat indirect conduction, and related parts of the air compressor are damaged due to overhigh temperature is avoided.

The temperature control valve piston 9-8 comprises a piston big end and a piston body, a transverse hole communicated with the side opening 9-3 is formed in the side wall of the piston body, and a longitudinal hole communicated with the transverse hole is formed in the end face of the piston body; the outer end of the large end of the piston is connected with a push rod of the temperature control valve core 9-7; the inner end of the oil shell through hole 9-9 is provided with a piston hole 9-14 matched with the piston body along the axial direction, and the piston hole 9-14 is communicated with the oil suction ports 9-12 of the stator and the rotor. In the scheme, when the oil circuit is in small circulation, oil flows to the transverse hole through the side opening 9-3, then flows to the piston hole 9-14 through the longitudinal hole, and finally flows into the stator and rotor oil suction openings 9-12; when the large circulation is carried out, the temperature control valve piston 9-8 is pushed by the push rod of the temperature control valve core 9-7 until the transverse hole is shielded by the piston hole 9-14, so that the communication between the stator and rotor oil suction ports 9-12 and the oil cavity 9-2 is cut off, oil liquid passes through the cooler from the cooler oil inlet 9-13 and then enters the stator and rotor oil suction ports 9-12 from the cooler oil outlet 9-11, and the large circulation of an oil path is realized. In the scheme, the temperature control valve piston 9-8 moves through the mutual matching of the piston body and the piston hole 9-14, and compared with other schemes that a push rod of the temperature control valve core 9-7 is matched with a corresponding hole, the scheme has the advantages that the contact area of the moving matching surface is larger, and the moving is stable and reliable. And the oil suction port 9-12 of the stator and the rotor and the oil cavity 9-2 are cut off through clearance fit between the piston hole 9-14 and the piston body, although the piston has a certain leakage amount, compared with other schemes using sealing elements, the structure is simple, the cost is low, and the oil suction port is particularly suitable for the working condition of air compressor oil cooling which has no strict requirement on the leakage amount.

The cross holes are distributed on the cross section of the piston body in a cross shape. The thermo valve piston 9-8 having the cross holes distributed in this way makes it unnecessary to consider the orientation when it is installed, i.e., to communicate with the side opening 9-3, and prevents the cross holes from being disconnected from the side opening 9-3 by the thermo valve piston 9-8 spinning during use.

The large end of the piston is provided with a shoulder end surface, and the temperature control valve spring 9-10 is arranged between the shoulder end surface and the bottom surface of the inner end of the oil casing through hole 9-9. After the spring is additionally arranged, the retraction force of the push rod of the temperature control valve core 9-7 can be ensured, so that the temperature control valve core 9-7 does not need to be in a relatively expensive self-rebounding type, and the cost is saved.

The temperature control valve piston 9-8 is fixed with a spring positioning shoulder on the piston body. Usually, the inner diameter of the temperature control valve spring 9-10 is larger than that of the piston body so as not to directly shield the transverse hole, and after the spring positioning shoulder is fixed, the temperature control valve spring 9-10 can be concentrically positioned on the piston body, so that the phenomenon that the temperature control valve piston 9-8 is clamped due to uneven spring force caused by deflection of the spring is avoided.

In addition, because the shape of the temperature control valve core 9-7 in the prior art is generally a cylinder with a circle of protruding shoulders, and the width of the protruding shoulders is small, the contact area between the temperature control valve core 9-7 and the inner surface of the oil shell through hole 9-9 is too small, so that the temperature control valve core is difficult to reliably fix along the axial direction, the condition of skew screwing often occurs, and the stroke of a push rod of the temperature control valve core is influenced after the temperature control valve core 9-7 is skewed, so that the valve core is not closed tightly. In order to avoid the above situation, one end of the temperature control valve sleeve 9-6 is propped against the shoulder of the temperature control valve core 9-7, and the other end thereof is propped against the screw plug 9-4; the side wall of the temperature control valve sleeve 9-6 is provided with an opening. The opening can be an opening of an I-shaped body formed by two circular rings and two connecting rods between the two circular rings, or an opening with a plurality of through holes drilled on the side wall, and the opening is recommended to be as large as possible so that oil can smoothly pass through the opening to be in contact with the temperature control valve core in the opening.

Description of the drawings:

as shown in fig. 4 and 5, one end of the valve block 6 is connected to the compressed air unit 4 by a hinge bolt, the other end of the valve block 6 is fixedly connected to the cooler 5, and the compressed air unit 4, the valve block 6, and the cooler 5 are integrally formed. The high-temperature lubricating oil flows from the outlet of the cooling pipeline of the compressed air part 4 through the valve block 6 to enter the inlet of the cooler 5, heat exchange is formed in the cooler 5, and the cooled lubricating oil flows back to the compressed air part 4 through the valve block 6 to form circulation.

The utility model relates to a motor drive direct-connected type water-cooled air compressor has integrateed booster pump 1, and booster pump 1 directly links motor 2, and compressed air portion 4 is connected with motor 2 through electromagnetic clutch, and booster pump 1 is the normal state of changeing, and electromagnetic clutch actuation when compressed air portion 4 need inflate, and compressed air portion 4 connects and begins work.

The water cooler is a plate structure, the plate cooler is formed by a plurality of punched corrugated thin plates according to a certain interval, the periphery of the punched corrugated thin plates is sealed by gaskets, and the punched corrugated thin plates are overlapped and compressed by a frame and a compression screw, four corner holes of the plate and the gasket form a fluid distribution pipe and a fluid collection pipe, and simultaneously, cold and hot fluids are reasonably separated to flow in flow channels on two sides of each plate respectively and carry out heat exchange through the plate.

The utility model discloses integrateed booster pump 1, saved booster pump motor, controller and high-pressure pencil, the cost is reduced has solved the problem of arranging the difficulty. The 4 water-cooling access of compressed air portion whole car water cooling system has both solved the high temperature problem that arouses because of the cabin seals and has solved the high problem of noise of forced air cooling air compressor machine.

The utility model discloses with compressed air portion 4 and booster pump 1 with a motor 2 drive, solved and installed compressed air portion 4 and booster pump 1 installation space problem alone, still solved the wind sound noise problem of air-cooled air compressor machine.

The utility model discloses integrated compressed air portion 4 and booster pump 1 as an organic whole, both the cost is reduced has solved the problem that is difficult to arrange because of the cabin space is limited again, through optimizing the forced air cooling for the water-cooling, has both solved the high temperature problem and has solved the high problem of noise of forced air cooling air compressor machine again.

Finally, the working principle and the dismounting mode of the part are described:

1. when the sliding vane type air compressor is in a cold state, namely when the oil temperature is lower than 88 ℃, the temperature control valve core 9-7 is not opened, and an oil path circulates a small circle to pass through a hole phi 5 on the temperature control valve piston, namely a transverse hole and a longitudinal hole, and enters a fixed rotor cavity. The oil entering the stator and rotor is ejected together with the compressed air. After being sprayed out, the mixture enters the stator and rotor cavities through phi 5 holes, namely the transverse holes and the longitudinal holes, and the process is repeated.

2. The temperature of the compressed air is raised to bring heat into oil along with the work done by the air compressed by the sliding vane type air compressor, when the oil temperature is 88 ℃, the temperature control valve core 9-7 is opened, the oil path goes through large circulation, as the temperature control valve core opens the phi 5 hole on the temperature control valve piston, namely the transverse hole and the longitudinal hole, and is blocked, lubricating oil firstly enters the cooler from the oil storage shell 9-1 and the cooler oil inlet 9-13, returns from the cooler oil outlet 9-11 after being cooled by the cooler and is sucked into the stator and rotor cavities, the oil entering the stator and rotor is sprayed out along with the compressed air, and then enters the cooler through the oil storage shell 9-1 and the cooler oil inlet 9-13 again after being sprayed out, and the process is repeated.

3. The installation steps are as follows:

1) the temperature control valve spring 9-10 is sleeved into the temperature control valve piston 9-8 and then integrally plugged into the oil shell through hole 9-9 of the oil storage shell 9-1.

2) The temperature control valve core 9-7 is sleeved into the temperature control valve sleeve 9-6 and then integrally plugged into the oil shell through hole 9-9.

3) The combined washer 9-5 is sleeved on the screw plug 9-4 and then integrally screwed into the oil casing through hole 9-9.

The dismounting steps are just opposite to the mounting steps, and the design life is the same as that of the sliding vane type air compressor because other parts do not need to be replaced, so that the dismounting work is only directed at the temperature control valve core, the temperature control valve plug is only required to be screwed down, and the temperature control valve core can be taken out after the temperature control valve sleeve is taken out.

By adopting the technical scheme of the temperature control valve, the technical effects are as follows:

1. this scheme has solved the problem that change the temperature control case and need dismantle the aircraft nose completely during maintenance.

In the prior art, when the temperature control valve core is replaced every year, the air filter cover, the air filter seat, the oil separation cover, the oil core, the large end cover assembly, the small end cover assembly and the stator and rotor assembly need to be detached in sequence, and all parts installed in the oil storage shell are detached to detach the temperature control valve assembly. After the temperature control valve assembly is disassembled, the elastic check ring for the hole and the temperature control valve gasket are disassembled, and then the temperature control valve core can be replaced. The structure of the temperature control valve assembly realizes maintenance and replacement of the temperature control valve core, and the temperature control valve core can be replaced only by unscrewing the screw plug.

2. The structure of the temperature control valve assembly avoids abnormal sound and air volume reduction caused by disassembling the whole machine head and replacing the temperature control valve core.

A large amount of practices in market prove that the temperature control valve element can be replaced only by completely disassembling the whole sliding-vane air compressor head in the prior art, the temperature control valve element is replaced after sales, the assembly environment and the precision of a workshop are not provided for replacement, the problems of abnormal sound of the head and reduction of air volume after assembly are greatly solved, and even more, the situation that the head is damaged cannot be guaranteed due to the assembly environment and the assembly precision. The whole machine head can not be disassembled and assembled any more, and the temperature control valve core can be replaced only by unscrewing the screw plug. Meanwhile, secondary disassembly and assembly caused by the fact that the whole machine head is disassembled and the temperature control valve core is replaced after the temperature control valve core is found to be poor in new assembly is avoided

3. The configuration of the present temperature control valve assembly reduces the leakage point of the temperature control valve assembly.

The current combination packing ring of prior art scheme is located between temperature control valve body and the oil storage shell, when the temperature control valve core is opened, if this combination pad became invalid or revealed, then can lead to the temperature control valve to open also not functional. The combined washer of the scheme is arranged between the oil storage shell and the screw plug, and the temperature control valve core is opened without influencing the temperature control valve core due to failure or leakage of the combined washer.

4. The structure of the temperature control valve assembly improves the maintenance efficiency, and the temperature control valve core can be replaced without disassembling the whole machine head, so that the maintenance efficiency is greatly improved.

5. The construction of the temperature control valve assembly achieves a cost reduction due to the integration of the temperature control valve body on the oil storage shell.

The temperature control valve body in the prior art scheme is integrated on the oil storage shell, so that compared with the prior art scheme, the oil storage shell has one less part, the casting and machining of one part are reduced, and the cost is reduced.
