The Relationship Between Impeller Diameter And Head Of Submersible Pump

Apr 23, 2024

The impeller diameter of the submersible pump will affect its head, under normal circumstances, the larger the impeller diameter, the higher the lift of the submersible pump.

First, the working principle of submersible pump

Submersible pump is a pump that can work in water, and its working principle is to combine the motor with the pump body to send the water to the outlet through the centrifugal force generated by the rotation of the impeller, so as to achieve the pumping effect of water.

Second, the relationship between the diameter of the impeller and the head of the submersible pump

The lift of the submersible pump refers to the maximum height that the pump can provide water, generally in meters. The impeller diameter of the submersible pump refers to the size of the impeller diameter of the submersible pump, generally in millimeters. There is a close relationship between the impeller diameter and the head of the submersible pump.

According to the principle of fluid mechanics, the centrifugal force generated when the impeller rotates is proportional to the diameter of the impeller, that is, the larger the diameter of the impeller, the higher the lift of the pump. Therefore, under normal circumstances, the larger the impeller diameter of the submersible pump, the higher the lift of the submersible pump, and the smaller the impeller diameter of the submersible pump is relatively low.

In addition to the impeller diameter, the lift of the submersible pump is also affected by other external factors, such as the speed of the pump, the shape of the impeller and other factors will have an impact on its lift.

There is a close relationship between the impeller diameter and the head of the submersible pump, the larger the impeller diameter, the higher the head of the submersible pump. However, in addition to the impeller diameter, there are other external factors that affect the head of the submersible pump. Therefore, when choosing a submersible pump, it is necessary to choose according to actual needs, and consider all aspects of the factors.
