摘要
输送液氧、液氮、液氩、LNG等液态气体的低温离心泵中使用的机械密封(接触型),其工作寿命受很多如液态介质种类、泵精度等客观因素制约。分析了影响低温机械密封工作寿命的因素,并给出操作建议。
The service life of mechanical seal(contact type)used in cryogenic centrifugal pump for conveying liquid oxygen,liquid nitrogen,liquid argon,LNG and other liquid gases is restricted by many objective factors such as liquid medium type and pump accuracy.The factors affecting the working life of cryogenic mechanical seal are analyzed and operation suggestions are given.
