离心泵的汽蚀与预防

Cavitation and Prevention of Centrifugal Pump

汽蚀是离心泵的一种不正常现象,为了防止离心泵汽蚀,就需要合理确定离心泵的安装高度,合适的汽蚀余量才能正确计算离心泵的安装高度,文章分别讲述了离心泵的四种常见汽蚀余量,并介绍了一些用于防止汽蚀发生的措施。

Cavitation is a kind of abnormal phenomenon of centrifugal pump, to prevent the occurrence of cavitation. It is reasonable to determine the height of the centrifugal pump. The appropriate cavitation margin determines the installation height of the centrifugal pump. The paper describes four common cavitation margin of centrifugal pump, and introduces some measures for preventing cavitation.
