Industrial pump applications often use variable frequency pumps, so what is the difference between variable frequency pumps and ordinary pumps? In order to better do the science popularization of industrial pump knowledge。
In fact, literally, I think we should all know that the variable frequency pump is actually the pump configuration of the motor for the variable frequency motor, because we usually say that the pump is directly connected, directly connected is the motor configuration is extended shaft, the pump body directly connected to the motor can be, there are vertical variable frequency pump or horizontal variable frequency pump, as shown below.
Do not have to say that we all know that the biggest advantage of inverter motor is energy saving, in addition to energy saving, for industrial motors, there are the following advantages:
1、 with the start function.
2、 electromagnetic design, reduce the stator and rotor resistance.
3、 Adapt to frequent speed change under different working conditions.
4、 to a certain extent, energy saving can achieve a stepless speed change, and changing the number of magnetic poles of the motor can only achieve a limited number of times.
