摘要
本文分析了以往用于测定叶片泵汽蚀性能的几种试验装置存在的问题,提出了一种新型的半开式试验装置,该装置具有系统自动平衡的特点,适合于扬程在 10m以上的各种叶片泵的汽蚀试验。
The problems existed in the past used test systems for measurement of the cavitation of the vane pump are analysed and a new semi-open test system is presented in this paper. The test system has the fea- ture of system auto-balance and is suitable for the cavitation tests of varied vane pumps with over 10-meter lifting.
