At installation, insufficient compression of the sealing pad behind the carbon ring seal of the expander results in oil entrance to expander body and to the corresponding pipeline. 由于膨胀机碳环密封后面的密封垫片在安装时未被充分压紧,使膨胀机机体及相应管道进油。
Compression: a mattress pad in the horizontal surface of the force applied vertically downward, causing the mattress by the force along the direction of surface displacement. 压缩量:在水平放置的床垫垫面上施加垂直向下的力,引起床垫表面沿受力方向的位移量。
