摘要
该文介绍了水泵汽蚀现象的原因及危害，提出要避免汽蚀现象，必须限据水泵样本上所规定的允许吸上真空度[Hs]或允许汽蚀余量[△h]，来合理地确立水泵的安装高程．
This paper gives the cause and harm of phenomenon of water pump corroded by vapour,and points out that the installation altitude of water pump is determined reasonably to avoid. the phenomenm of water pump corroded by vapowr with the corroding surplus[△h]permitted or the absorbing racuum degree [Hs]permitted by the pump sample.
