摘要(Abstract):

从吸水池尺寸形状、进水管、抽送介质的物理化学特性、泵必需的汽蚀余量和汽蚀比转速等方面 ,讨论了循环水泵汽蚀产生的原因 ,并提出了改造方案。
The reasons which caused the circulation water pump's cavitation was discussed, Some suggestion was introduced, which include the cistern's dimersion and figure, water pipe, the physical chemical characteristic of the medium, the nesessary HPSH and cavitation NS of the pump etc.
