Description

Technical Field

[0001] This invention relates to the field of air compressor equipment technology, specifically a water-cooled rail air source system. Background Technology

[0002] The track ventilation system is an indispensable core piece of equipment in the operation of rail transit vehicles. It provides a continuous, stable, dry, and clean supply of compressed air for key functional systems such as train braking, door control, air spring suspension, and pantograph raising and lowering. A complete ventilation system typically includes an air compressor, a cooling device, a dryer, a precision filter, and connecting pipelines. Through coordinated work, they complete the entire process of air compression, cooling, dehydration, and purification, thereby ensuring the safe and reliable operation of all critical train functions.

[0003] With technological advancements, the rail transit sector is gradually adopting oil-free air compressors to replace traditional oil-lubricated air compressors. Oil-free air compressors output compressed air without oil, simplifying the structure of downstream air handling systems. In particular, they eliminate the need for complex oil removal processes, reducing system maintenance difficulty and costs, and are also more environmentally friendly.

[0004] However, existing oil-free air compressors in rail ventilation systems generally face technical bottlenecks in cooling and heat dissipation. Current mainstream designs primarily employ air cooling to cool the compressor's core compression disc. This method relies on a fan blowing ambient air across the disc surface to remove heat. Under prolonged high-load operation, the compression disc generates significant heat due to the intense air compression process. Air cooling has low efficiency, making it difficult to dissipate this heat quickly and effectively. This results in persistently high operating temperatures for the compression disc. Prolonged high-temperature operation accelerates the aging and deformation of the disc material, ultimately causing disc damage, compressor malfunctions, and impacting train safety. Therefore, the existing heat dissipation methods are a significant factor limiting the reliability and lifespan of oil-free air compressors. Summary of the Invention

[0036] Please see the appendix Figure 1 and attached Figure 2 A three-phase asynchronous motor 5 is fixedly connected to the middle of the frame 43. The air compressor 2 is fixedly connected to the output end of the three-phase asynchronous motor 5. An air compressor housing 15 is fixedly connected to the outside of the air compressor 2. A fixing block 16 is fixedly connected to the end of the air compressor housing 15.

[0037] Specifically, the three-phase asynchronous motor 5 is used to provide power for the operation of the air compressor 2; the air compressor 2 is used to compress air; the air compressor housing 15 is used to protect the internal structure of the air compressor 2; the fixing block 16 is used to connect the anti-detachment steel wire rope, serving as the connection point of the safety anti-fall structure, preventing the unit from falling accidentally when the connection between the air compressor 2 and the frame 43 fails through the shock-absorbing pad.

[0038] Please see the appendix Figure 1 and attached Figure 3 A second anti-detachment steel wire rope 14 is fixedly connected to one end of the frame 43 near the air compressor 2. A first anti-detachment steel wire rope 13 is fixedly connected to the middle of the frame 43. The second anti-detachment steel wire rope 14 is fixedly connected to the bottom inner side of the fixing block 16. The first anti-detachment steel wire rope 13 is fixedly connected to the bottom inner side of the three-phase asynchronous motor 5. Multiple anti-detachment plates 20 are provided on the inner side of the end of the frame 43, respectively located in the middle and end of the frame 43. Shock-absorbing pads 17 are provided on the outside of the anti-detachment plates 20. A double-tower filter 18 is fixedly connected to the end of the frame 43. The double-tower filter 18 is one of the air dryers 7 and is the same part.

[0039] Specifically, the second anti-detachment steel wire rope 14 and the first anti-detachment steel wire rope 13 serve as secondary safety protection devices, respectively connecting the fixing block 16 and the three-phase asynchronous motor 5, to prevent the equipment from falling when the shock absorption fixation fails; the anti-detachment plate 20 is used to cooperate with the installation structure to limit the extreme displacement of the equipment; the shock-absorbing pad 17 serves as an elastic connection medium between the equipment and the frame 43, to support the weight of the equipment and isolate the vibration and noise generated during operation; the dual-tower filter 18 is the specific structural form of the air dryer 7, which uses the principle of alternating adsorption of the dual towers to remove moisture from the compressed air.

[0040] Working principle: When this water-cooled rail air supply system is running, it mainly includes compressed air processing, coolant circulation and heat dissipation, and electrical control and safety protection mechanisms.

[0041] In the compressed air processing flow, the three-phase asynchronous motor 5 is energized to provide power to the air compressor 2. External air, under negative pressure, passes through the air filter 6 to remove dust and impurities, and then enters the air inlet 26 of the air compressor 2 through the fourth air passage pipe 47. The vacuum indicator 25 monitors the intake resistance during this process to indicate the filter element status. The air is compressed inside the air compressor 2, and the resulting high-temperature, high-pressure gas is discharged from the compressed air outlet 29 and enters the air passage 44 inside the radiator 3 via the first air passage pipe 36. The cooling fan 21 generates forced convection to cool the high-temperature compressed air in the air passage 44. The cooled compressed air is then transported to the one-way valve 12 through the second air passage pipe 38, and subsequently enters the air dryer 7. Inside the air dryer 7, the dual-tower filter 18 removes moisture from the air by alternating operation of the adsorbent. The dried air enters the input end of the precision filter 8 through the connecting pipe 19. The precision filter 8 further filters out dust and impurities, and finally the clean compressed air is delivered from the output end of the precision filter 8 to the subsequent system via the air passage pipe 37 and the first safety valve 10.

[0042] In the coolant circulation and heat dissipation process, water pump 1 starts working, drawing in and pressurizing the low-temperature coolant stored in storage tank 4 through the fourth water passage pipe 40. The pressurized coolant is injected into the air compressor water channel inlet 33 of air compressor 2 through the second water passage pipe 39, first entering the lower part 32 of the air compressor static compression plate water channel, and then entering the air compressor dynamic compression plate water channel 34 through the air compressor water channel connecting hole 27, absorbing the heat generated by the dynamic compression plate. Afterwards, the coolant again enters the upper part 30 of the air compressor static compression plate water channel separated by the air compressor static compression plate water channel partition 31 through the air compressor water channel connecting hole 27, further absorbing the heat from the static compression plate. The high-temperature coolant carrying heat is discharged from the air compressor water channel outlet 28 and enters the water channel 9 inside radiator 3 through the first water passage pipe 35. In radiator 3, the heat of the high-temperature coolant is dissipated into the air, and the temperature decreases. After cooling, the coolant flows back to the storage tank 4 through the third water pipe 46 to complete the circulation, ensuring that the heat generated by the compression disc of the air compressor 2 is continuously removed.

[0043] In terms of electrical control and safety protection, the electrical warning box 24 transmits signals to the solenoid valve in the air circuit of the radiator 3 and the air dryer 7 via the solenoid valve cable 42 and the air dryer cable 41, respectively, to control the operation of the system. At the same time, the timer 22 and the counter 23 are used to record the operating status of the equipment. In terms of physical structural safety, the air compressor 2 is connected to the second anti-detachment steel wire rope 14 via the fixing block 16, and the three-phase asynchronous motor 5 is connected to the first anti-detachment steel wire rope 13. Together with the anti-detachment plate 20, it prevents the unit components from falling in the event of accidental failure of the shock-absorbing connection of the shock-absorbing pad 17.
