Booster Pump Factory introduces Agricultural Centrifugal Pump refers to the number of times the pump shaft rotates per unit time. It is usually expressed as n, and the unit is r/min. Generally, the small centrifugal pump is 2900 r/min or 1450 r /min higher, and the large centrifugal pump is 970 r/min or 730 r/min lower. In the case of a certain speed, the flow, head, and power are certain values. The rotational speed of the centrifugal pump is The difference between 1450r/min and 2900r/min. The rotational speed of a centrifugal pump refers to the revolutions per minute of the centrifugal pump shaft. It is represented by the symbol n. The rotational speed refers to the revolutions per minute of the centrifugal pump shaft when the power machine drives the centrifugal pump to pump water, which is represented by the symbol n, and the unit is r/min. In our usual centrifugal pump applications, there are two common centrifugal pump speeds: one is 1450r/min, and the other is 2900r/min. What is the diffe rence between the centrifugal pump speed of 1450r/min and 2900r/min?

1.1450r/min centrifugal pumps are generally low-lift and high-flow pumps with low-speed 4-stage motors, while 2900r/min centrifugal pumps are high-lift centrifugal pumps and high-speed 2-stage motors.

2. Under the condition that the flow and head requirements of the centrifugal pump are the same, the low-speed centrifugal pump will have lower noise than the high-speed pump when the flow and head are already running. Compared with

high-speed centrifugal pumps, low-speed centrifugal pump impellers have better wear resistance and relatively less vibration to the ground;

3. Under the condition that the flow and head requirements of the centrifugal pump are the same, the price of the centrifugal pump with low speed is also expensive. This is because a class 4 motor has more copper wire in the wire wrap

than a class 2 motor.

4. In terms of design pursuit, the high-speed centrifugal pump is more efficient than the low-speed centrifugal pump.
