目前,煤矿、电厂排水用的离心泵在运行中发生汽蚀现象是相当普遍的,其原因较多,有选型、安装、操作、使用等多种问题。虽然国内外对汽蚀的机理及防止汽蚀破坏等方面进行了大量研究,但至今对这一问题的认识仍有待深化,下面就联系本人工作实际,谈谈汽蚀的预防措施。1汽蚀的影响因 At present, cavitation in the operation of centrifugal pumps used in drainage of coal mines and power plants is quite common for many reasons, such as selection, installation, operation and use. Although a great deal of research has been done at home and abroad on the mechanism of cavitation erosion and the prevention of cavitation damage, so far the understanding of this issue needs to be further deepened. Here to talk about the practical work of cavitation erosion prevention measures. 1 Cavitation impact factors
