PARAMETERS OF THE CENTRIFUGAL PUMP WITH THE CONVERGING WHEEL IN ELEVATED MODE
In article it is shown that a centrifugal pump with a wheel converging at a higher mode than the design mode, i.e. the mode of maximum efficiency, achieves efficiencies substantially higher than the pump with the diffuser wheel. At the same time in design mode, the efficiency of the centrifugal pump with the converging wheel slightly higher than the efficiency of a centrifugal pump with diffuser wheel. This, as will be shown, due to the fact that the flow in the converging wheel increases the theoretical pressure of the wheel. Experimental study of centrifugal pumps with converging wheels showed that with increasing confusingly increases the pressure and the pump efficiency while reducing pulsation and vibration of the pump. This increase in pressure is significant.
