Second, oil does not come into contact with the compressed gas external drive mechanism, such as in reciprocating compressor crankcase parts, crank pin, crank bearings, connecting rod slide, slide, crosshead; and speed rotary compressor bearings , gear and other growth.

其二为油不与压缩气体接触的外部传动机构，如往复式压缩机曲轴箱中零件、曲柄销、曲柄轴承、连杆滑块、滑道、十字头；回转式和速度式压缩机的轴承、增速齿轮等。

In addition there will be a part of compressor running metal end of the refrigerant itself contains a certain amount of impurities, as the refrigerant in the refrigeration system, circulation changes, which will plug into the expansion valve valve Bellows Seal Valves hole, into the compressor will nap, and scratching the cylinder.

另外压缩机运行后也会有一部分金属末，制冷剂本身也含有一定数量的杂质，随着制冷剂在制冷系统内循环变化，它们进入膨胀阀就会堵塞阀孔，进入压缩机就会拉毛和刮伤汽缸。

To study the performance of screw compressor, the key component in heat pump chiller, a mathematic model for simulating the behavior of the compressor's working process is presented in this paper, based on the thermodynamics of mass-variable system and the p-V indicator diagrams acquired by experiment.

为此，本文在实测压缩机在经济器补气工况、部分负荷工况、不同冷却方式等工况下p-V指示图的基础上，并基于变质量系统热力学原理，建立了螺杆制冷压缩机工作过程热力学数学模型，考虑了喷油、泄漏、热交换及补气等因素对工作过程的影响。

The PER of the unit can be improved if engine speed and compressor speed are matched well according to the capacity of gas engine and refrigerating compressor and operating requirement.

而根据燃气机与压缩机容量的大小和机组运行要求，合理匹配燃气机与压缩机之间的转速，可以提高机组整体的运行性能。
