摘要:蒸发器在工作中经常会遇到出料困难的问题,即在泵的入口处产生汽蚀。汽蚀是离心泵的特有现象,而其产生汽蚀的原因却不是单一的。一种是料液在叶轮入口处自身形成的汽蚀现象;一种是料液在蒸发过程中二次蒸汽及不凝性气体在泵入口处产生堆积来不及释放形成的汽蚀;还有另外一种为设备外界空气漏入设备内所形成的汽蚀。

Abstract: The evaporator often encounters discharge problems during operation. The cavitation is generated at the entranceof the pump. Cavitation is a special issue for centrifugal pump,but the causes of cavitation is not single. One cavitation iscaused by the material liquid formed at the entrance of the impeller. One is caused by secondary steamand non-condensablegas produced during liquid evaporation that not yet released. The outside air leaked into the equipment also causing anotherkind of cavitation.Key words: evaporator;cavitation;reason;influence;solution
