分析了超低比转速高速诱导轮高心泵容易产生不稳定特性的原因和机理，并提出了控制措施，试验表明采用合理设计复合叶轮等过流部件以及在诱导轮和离心轮前加孔板能够使高速泵获得稳定的扬程流量特性线．
The reason and mechanism of high instability characteristic of high-speed inducer with high speed and high speed induced wheel are analyzed and the control measures are put forward. The test shows that using reasonable design of overcurrent components such as composite impeller and the front orifice of inducer and centrifugal wheel Enables high-speed pumps to achieve a steady headflow characteristic line.
