What is the difference between a variable frequency boiler pump and a normal boiler pump?

In fact, the key to this problem is to figure out what is the frequency, why should the frequency, know the problem we can easily understand the variable frequency boiler and ordinary boiler pump is different, we often say that the frequency conversion is a motor Frequency conversion process, through the motor frequency to change the motor speed, so as to achieve the flow of the pump and other technical parameters of the adjustment, play a control role.Click to know Feedwater pumps ,
 Frequency converter boiler pump and the difference between ordinary boiler pump:
        1, the variable frequency pump motor is the variable frequency motor, the ordinary motor of the pump motor
        Variable frequency motor design takes into account the motor running to low speed when the heat problem, using a separate powerful fan, anti-frequency converter in the high harmonics also do the corresponding treatment. Frequency conversion pump is the frequency change, used to control the speed, to achieve the required water flow.

        The motor is no difference, that is, in front of the motor plus inverter control, inverter motor cooling fan is independent, which is to prevent the motor running for a long time low frequency caused by insufficient heat and specially designed, and ordinary motor cooling fan and motor rotor is This is the biggest difference in appearance.
