摘要
通过对气蚀产生原因的分析和实验研究,表明煤矿主排水泵叶轮破坏主要是气蚀造成的,提出了进一步净化矿井水是避免煤矿主排水泵气蚀和延长叶轮寿命的一个有效途径。
According to the causal analysis of cavitation by experiement, the author has pointed out that cavitation leads to the damage of impeller in drainage pump, and put forward an effective way to avoid cavitation damage in main mine drainage pump and improve impeller＇s service life by purifying mine water.
