Adjustment method of multistage centrifugal pump for mine
The working principle of the multi-stage centrifugal pump for mining is the same as that of the ground centrifugal pump. When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller will be thrown to the impeller from the center of the impeller along the flow path between the blades under the action of centrifugal force. Because the liquid is affected by the blades, the pressure and speed increase at the same time, and it is guided to the next-stage impeller through the flow passage of the guide shell. In this way, it flows through all the impellers and the guide shell one by one to further make the liquid Pressure energy increases. After stacking each impeller step by step, a certain head is obtained and the downhole liquid is lifted to the surface. This is the working principle of the stainless steel multi-stage pump.
