Dynamic illustration of the working principle of D-type horizontal multistage centrifugal pump

28 Jul 2021Email

The D-type horizontal multistage centrifugal pump has high efficiency and can meet the needs of high-lift and high-flow working conditions. It has been widely used in petrochemical, chemical, electric power, construction, fire protection and other industries. Before making the selection, we must understand the working principle of the D-type horizontal multi-stage pump.

horizontal multistage centrifugal pump

 

The working principle of the D-type horizontal multistage pump is the same as that of the ground centrifugal pump. It also relies on the rotation of the impeller to obtain centrifugal force and thus the material. When the motor drives the impeller on the shaft to rotate at high speed, the liquid filled in the impeller will be thrown from the center of the impeller along the flow path between the blades to the periphery of the impeller under the action of centrifugal force. Because the liquid is under the action of the blades, the pressure and speed are At the same time, it increases and is guided to the next-stage impeller through the flow channel of the guide shell, so that it flows through all the impellers and the guide shell one by one, further increasing the pressure energy of the liquid. After stacking each impeller step by step, a certain head is obtained and the downhole liquid is lifted to the surface.
