摘要
通过对汽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汽蚀造成的 ,提出了进一步净化矿水是避免煤矿主排水泵汽蚀和提高叶轮寿命的一个有效途径。
By analyzing reasons of creating cavitaton and testing,it is showed that cavitation damages the impeller of the chief draining pump in coal mines,this paper puts forward that mine water is cleaned further an effective way of avoiding cavitation and increasing longevity of the chief draining pump in coal mines.
