汽车空调器在汽车中越来越被广泛采用。一般汽车的空调器,包括有氟利昂活塞式制冷压缩机、冷凝器、蒸发器、贮液器、视液镜、膨胀阀、鼓风机和电气自动控制器件等。压缩机是一主要部件,它的使用和发展已有几十年的历史,大致可分为径向活塞式(活塞的运动方向与主轴垂直)和轴向活塞式(活塞运动方向与主轴平行)二种。但轴封渗漏氟利昂致冷剂,是车用活塞式制冷压缩机的致命弱点。尽管设计、制造、使用部门均采取了各
Car air conditioners are increasingly used in cars. General car air conditioners, including Freon piston refrigeration compressors, condensers, evaporators, reservoirs, sight glass, expansion valves, blowers and electrical automatic control devices. Compressor is a major component, its use and development has been decades of history, can be divided into radial piston (piston movement direction and spindle vertical) and axial piston (piston movement direction parallel to the spindle) Two kinds. However, the leakage of freon refrigerant shaft seal, is a car piston refrigeration compressor a fatal weakness. Although the design, manufacture, use department have taken all
