How do you change the speed of a water pump?
Adjusting the speed is to adjust the pump power, head and flow. The two-phase ordinary water pump can adjust the speed by changing the input voltage to change the power of the pump, or by inputting the PWM adjustable duty cycle power supply.
How do you adjust the flow rate of a pump?
For every pressure, the pump will only deliver one specific flow rate. Therefore, to control the flow of a centrifugal pump, simply set the output pressure to the point on the P-V diagram that allows the pump to deliver the desired flow rate. The output pressure of the pump is set using a back pressure regulator.
Can you adjust the speed of a centrifugal pump?
The optimal matching of centrifugal pump speed and operation parameters (characteristic data) can be achieved by speed adjustment. It can be realized by changing the speed regulating motor to achieve 2-4 kinds of polar logarithm.
