Description
[technical field]
The utility model relates to the Reciprocting piston compressor technology in the automobile manufacturing field, and concrete is a kind of automobile air conditioner compressor of big discharge capacity.
[background technique]
Common coach air conditioner compressor is generally four cylinder Reciprocting piston compressors at present, and discharge capacity has four kinds of 400cc, 470cc, 560cc, 650cc, can satisfy the needs of existing 8～12 meters coach air conditioners.But, in recent years, city bus develops toward the direction of maximization, low-floor, the bus of 12 meters long and low-floor has appearred surpassing, such bus inner space has increased many, the compressor cooling that re-uses the 650cc discharge capacity air conditioning quantity deficiency that seems needs to use six cylinder compressors of bigger discharge capacity.But use six cylinder compressors to compare with use four cylinder compressors and have following difference: 1. compressor weight will increase by 30%, and the oil consumption of bus running is increased; 2. the compressor cost will increase by 50%, make the price of bus higher; 3. the compressor external dimension increase, and need to increase the space that compressor is installed in the engine bin, need to change the relevant design of bus.
The another kind of method that solves is, transforms the structure of four cylinder compressor systems, makes its power obtain bigger raising to satisfy the needs of overlength super large bus.
Because the running environment of coach air conditioner compressor is poor; running environment not as sedan car; the heat that the friction pair of air-conditioning compressor shaft gland produces is big; and it is obviously not enough by the effect of lubricant oil heat radiation; cause the damage or the inefficacy of axle envelope because of long high temperature through regular meeting; therefore, most of fault of compressor is caused by the problem that axle seals at present.
The shaft seal structure of coach air conditioner compressor commonly used is seen accompanying drawing 5 at present, wherein, axle envelope 21 is mechanical seal, by kinetic friction ring 22, seal ring of moving ring 23, spring seat 24, spring 25, static friction ring 26, stationary ring seal ring 27 constitutes, kinetic friction ring 22 is a friction pair with the seal face that stationary ring seal ring 27 is formed, seal ring of moving ring 23 plays auxiliary seal with stationary ring seal ring 27, seal ring adopts rubber material to make, and the heat-conducting property of rubber is poor, most of heat that friction pair produces can only conduct by lubricant oil, and the radiating effect of lubricant oil is obviously not enough.
