本文简要叙述防止或减轻泵站水泵汽蚀的措施和应注意事项等内容,供泵站设计和运行人员参考。一熟悉水泵汽蚀性能掌握其变化规律由于混流泵的汽蚀性能变化规律介于离心泵与轴流泵的汽蚀性能变化规律之间,故这里仅叙述离心泵与轴流泵的汽蚀性能。离心泵的汽蚀性能如图1所示。从图中可以看出,离心泵的允许真空吸上高度 This article briefly describes the measures to prevent or reduce pump cavitation in pump stations and matters needing attention such as pumping station design and operational personnel for reference. A familiar pump cavitation performance to master its variation law Because of the variation of the cavitation performance of the mixed flow pump is between the centrifugal pump and the axial flow pump cavitation performance variation, so here only describes the centrifugal pump and axial flow pump cavitation performance . Centrifugal pump cavitation performance shown in Figure 1. As can be seen from the figure, the centrifugal pump allows the vacuum suction height
