Description of drawings
In order to be illustrated more clearly in the utility model embodiment's technological scheme, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation at auxiliary compressor provided by the utility model station.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 shows a kind of structure at above-mentioned auxiliary compressor station, comprising: by oil-free air compressor 1, air-strainer 2, radiator 3, exsiccator 4, oily dirt filter 5, pressure regulator valve 6 and the safety check 7 of direct current generator 11 drivings.
Wherein, the air inlet port of oil-free air compressor 1 is connected with air-strainer 2, the output port of oil-free air compressor 1 is connected with the air inlet port of radiator 3, the output port of radiator 3 is connected with the air inlet port of exsiccator 4 (Fig. 1 part that dotted line encloses), the output port of exsiccator 4 is connected with the air inlet port of oily dirt filter 5, and the output port of oily dirt filter 5 is connected with safety check 7 by pressure regulator valve 6.
When working at the auxiliary compressor station, direct current generator 11 drives oil-free air compressor 1 and will compress through air-strainer 2 filtered airs, when the pressure of oil-free air compressor 1 compressed air satisfies the exhaust pressure of pre-provisioning request, pressurized air is discharged by the output port of oil-free air compressor 1, enter radiator 3 cooling of dispelling the heat, with carrying out drying process after the pressurized air of cooling enters exsiccator 4, through oily dirt filter 5 it is filtered again, pressurized air after the filtration is regulated compressed-air actuated pressure to prevent overpressure or low excessively through pressure regulator valve 6 again, at last, pressurized air through pressure regulation is discharged by safety check 7, can using with the gas system for locomotive.
Preferably, can be used safely, between exsiccator 4 and oily dirt filter 5, also high-pressure safety valve 8 can be set in order to ensure pressurized air.
In another embodiment, high-pressure safety valve 8 also can be connected with the one-way valve 9 that prevents that ambient air from refluxing.
Preferably, the drainage port of exsiccator 4 also can connect regenerated wind jar, 10, and exsiccator 4 inside are provided with the solenoid valve in the drainage loop that can control exsiccator: when motor power supply auxiliary machine station is in running order, electromagnetic valve is drained the loop and is in closed condition, and the auxiliary machine station is moved according to above-mentioned workflow; When the outage of auxiliary machine station was shut down, all electrical parts of auxiliary compressor station also cut off the power supply and are in off position, and electromagnetic valve drainage loop is on state.Because oil-free air compressor 1 is no longer worked; just can't produce pressurized air again; air pressure in the exsiccator 4 will reduce; and in this moment regenerated wind jar, 10 owing to filled pressurized air; its air pressure is greater than the air pressure in the exsiccator 4; so the pressurized air in the regenerated wind jar, 10 is pressed in the exsiccator 4; and cause the petcock of exsiccator 4 to be opened; the water molecule that is adsorbed in the exsiccator 4 and other particle are under compressed-air actuated effect; be excreted in the eduction gear in the exsiccator 4 by draining the loop, thereby realized shutting down back exsiccator 4 automatic pollution discharge; functions/drying regeneration.
In other embodiments, also can be provided with the high temperature protection switch in the air compressor 1.When the temperature of air compressor 1 was too high, the high temperature protection switch can cut off the power supply automatically, to play the effect of power-off protection.
Above-mentioned auxiliary compressor station can comprise any one or the combination in any in high-pressure safety valve 8, one-way valve 9, the regenerated wind jar, 10.
Need to prove that the auxiliary compressor station among above-mentioned all embodiments is applicable in the electric locomotive, also can be used on subway and the inter-city train.
With the oil-free air compressor in the auxiliary compressor station of railway locomotive special use is example, and the performance of oil-free air compressor is as follows:
The progression of oil-free air compressor is single stage compression, adopts vertical compressor, and bent axle and cylinder are lubricated without lubricant oil, and the body of oil-free air compressor and motor adopt the connecting mode of direct connection, and control mode is automatically controlled Automatic Control mode.Oil-free air compressor is completely without oily reciprocating piston formula air compressor, the piston ring on the oily reciprocating piston formula air compressor and the material of guide ring adopt the filled polytetrafluoroethylene self lubricating material, in use, motion along with piston ring (piston ring is made by the filled polytetrafluoroethylene self lubricating material), cylinder surfaces will cover the piston ring abrasive material of last layer densification gradually, it is filled polytetrafluoroethylene, so the friction factor between piston ring and the cylinder surfaces will reduce gradually, the wear of piston-rings amount also reduces thereupon gradually, the frictional loss of compressor simultaneously also can descend, the idle work that is caused by frictional loss also reduces thereupon, thereby efficient improves.Can reach 10000 hours the working life of air compressor with piston ring of filled polytetrafluoroethylene self lubricating material, reached not only environmental protection but also non-maintaining effect.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiments shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
