Abstract:
To investigate the effect of splitter blade inducer and variable pitch inducer on the hydraulic performance and anti-cavitation performance of the centrifugal pump, experiment and numerical simulation were carried out for the high-speed centrifugal pump with pre-positioned inducer.External characteristics experiments reveal that pre-positioned splitter blade inducer or variable pitch inducer has little influence on the efficiency of a high-speed centrifugal pump.Compared with the pre-positioned variable pitch inducer, the head of the centrifugal pump with the pre-positioned splitter blade inducer is decreased significantly.The results of the cavitation experiments show that, under the small flow condition, the anti-cavitation performance of the centrifugal pump with pre-positioned splitter blade inducer is improved.Under the large flow condition, the anti-cavitation performance with a pre-positioned variable pitch inducer is improved, and they are similar under other conditions.The numerical simulation results show that, under the large flow condition, the head of the splitter blade inducer is lower observably, which cannot meet the inlet energy requirement of centrifugal impeller, so the anti-cavitation performance of the centrifugal pump with pre-positioned splitter blade inducer is deteriorated.
