摘　　要：液击是往复式压缩机的致命杀手,往往会在很短时间内造成阀片破碎、连杆和曲轴弯曲甚至断裂。液击是由回液、带液启动等引起的,是系统问题在压缩机上的表现。提升制冷系统的设计、施工和维护技巧可以从根本上防止液击的发生,正确选择和安装膨胀阀、气液分离器、热气旁通阀和曲轴箱电热器、定时化霜、以及避免库温频繁波动是防止回液的具体措施。Being the notorious compressor killer, slugging may break the valve reeds, connecting rods and crankshafts in seconds. Slugging is the result of system problems including floodback and flooded start,and therefore should be avoided or prevented by improving development and maintenance skill, particularly the skill on selection and application of TXVs,hot gas bypass valves, accumulators, crankcase heaters,as well as maintaining ice -free evaporators and cold warehouse temperature.
