摘要
喘振是磁悬浮离心式压缩机极常见的故障之一,而且危害极大。分析了磁悬浮离心式压缩机产生喘振的机理、原因,提出了如何在空调负荷降低时预防磁悬浮离心式压缩机的喘振,提高其运行可靠性及效率。
Surge is one of the most common faults of oil free centrifugal compressor with great harm.In this paper,the mechanism and cause of surge of oil free centrifugal compressor are analyzed,and the method is puts forward to prevent surge of oil free centrifugal compressor when air conditioning load is reduced,so as to improve the operation reliability and efficiency.
