Frequency pump and ordinary pump difference in where

Often someone will ask us a question, what is a variable frequency pump? What is the difference between him and the ordinary pump? In fact, the key to this issue is to figure out what is the frequency, why variable frequency, we know the problem is very easy to understand the difference between ordinary and variable frequency pumps. We often say that the frequency conversion of the motor is a frequency conversion process, through the frequency of the motor to change the motor speed, so as to achieve the pump flow head and other technical parameters of the adjustment, play a role in control. Variable frequency pump frequency refers to the motor, variable frequency pump should be driven by the variable frequency motor pump frequency is adjustable frequency, the variable frequency motor is able to adjust the speed to adjust the flow, to save energy, as well as the starting current is small, the maintenance workload is small advantage. Ordinary pump is driven by an ordinary motor pump rotation, the so-called power frequency motor. Our daily frequency of 50Hz, not speed. Pump adjustment flow through the valve to achieve the same throttle, so no energy.
