汽蚀的危害及防治措施

Hazards of cavitation and prevention.

阐述了汽蚀的成因及危害,介绍了防治泵发生汽蚀的3类措施,即提高泵的有效汽蚀余量,降低泵的必需汽蚀余量以及其他措施。

This paper describes the cause of forma- tion of cavitation and it' s hazards.Then it introduces three kind measures to prevent cavitation:increasing effective net positive suction head of pumps,reducing net positive suction head and lowering necessary net positive suction head.
