减轻轴流泵的汽蚀及其修补措施轴流泵的汽蚀是由泵的本身汽蚀性能和装置使用条件决定的，为改善使用条件。减轻汽蚀危害，应在泵的装置合理布置和运行方面多加考虑，做好以下几方面工作：（１）正确确定轴流泵的安装高程设计水泵站时，应使装置汽蚀余量大于水泵的允许汽蚀... Mitigation of axial flow pump cavitation and its repair measures Axial flow pump cavitation is determined by the pump cavitation performance and device conditions, in order to improve the conditions of use. To reduce the cavitation damage, more consideration should be given to the rational arrangement and operation of the pump unit, and the following work should be done: (1) Correctly determine the installation elevation of the axial flow pump When designing the pump station, make the equipment NPSH greater than the water pump Allow cavitation ...
