摘要
随着密封技术的不断发展,机械密封(接触式)用于输送液氧、液氮、液氩、LNG等液态气体的低温离心泵,其使用寿命受到诸多客观因素的限制,如根据液体介质的种类、泵的精度等,分析了影响低温机械密封工作寿命的因素,并给出了操作建议。
With the continuous development of sealing technology,mechanical seals(contact type)are used for cryogenic centrifugal pumps conveying liquid gases such as liquid oxygen,liquid nitrogen,liquid argon,LNG,etc.Their service life is limited by many objective factors.For example,according to the types of liquid media,pump accuracy,etc.,the factors affecting the service life of cryogenic mechanical seals are analyzed,and the operation suggestions are given.
