Research on the Optimisation of Vane Shape Line and Centrifugal Pump Performance
Taking a certain type of centrifugal pump as the research object,the relationship between the vane outlet side inclination and the performance of a certain type of centrifugal pump as well as the influence of the vane wrapping angle on the performance of a certain type of centrifugal pump were studied.Firstly,under the premise that all external conditions remain unchanged,the corresponding vane outlet inclination angle is set;through experiments to compare the performance of the impeller under different vane outlet inclination angles,the optimal vane outlet inclination angle of a certain type of centrifugal pump is 76°.Under the premise of maintaining the optimal blade outlet inclination angle,different blade package angles are chosen to design the corresponding impeller,and finally,after experimental comparison and analysis,it is concluded that:under the premise of the optimal blade outlet inclination angle of 76 °,when the blade package angle of 195 °,a certain type of centrifugal pump can have the highest performance,which is about 3％higher than that of the impeller designed with other blade package angles.
