Abstract：The methods to reduce centrifugal pump′s power consumption and to avoid motor overload have been discussed.The method to reduce power by clogging flow passage has been presented.Two attempts on IS 50-32-160 non-overload centrifugal pump have been carried out by using the software FLUENT to forecast the performance.After clogging flow passage for second time,the maximal power was reduced by 10.4% and the non-overload characteristic had been presented.When the flow passage was clogged by 1/4,the proportion between inlet and outlet among two blades was changed to 1.16.The results of forecast are as following: adopting correct method of clogging flow passage,reducing the power of centrifugal pumps,thus their efficiency would be improved.The correct method of clogging flow passage must consider two factors,the ratio of clogging flow passage and an effective area proportion between inlet and outlet among two blades.
