全封闭压缩机曲轴通常以约3500r.p.m的速度回转。对曲轴轴承和其它运运部件供给适量的润滑油是非常重要的。冷冻润滑油贮存在压缩机壳体下面的油池里,通常是用离心泵将油压送到压缩机,润滑各部件。在制冷循环过程中,因为润滑油与制冷剂蒸汽的亲和特性,有部份油与制冷剂一起运行。制冷系统仅配置一台压缩机,同行的润滑油最终会回到压缩机壳体内。但在配置二 Fully enclosed compressor crankshafts typically rotate at about 3500 r.p.m. It is important to supply the right amount of lubricant to crankshaft bearings and other shipping components. Refrigerated oil stored in the oil tank below the compressor housing, the pump is usually used to send hydraulic pressure to the compressor, lubrication of various components. During the refrigeration cycle, some of the oil is running with the refrigerant because of the affinity of the lubricant with the refrigerant vapor. Refrigeration system is equipped with only one compressor, the same line of lubricant will eventually return to the compressor housing. But in the configuration two
