The working principle of the variable frequency pump is that it can be operated from power frequency to low frequency, because a frequency converter is installed inside.
The frequency converter has the basic functions of voltage regulation, frequency modulation, voltage stabilization, speed regulation, etc. It has applied modern science and technology to adjust the frequency without changing the voltage, or to change the voltage without changing the frequency, and to adjust the speed according to the load needs. Although the price is expensive, the performance is good, the structure is complex, but the use is simple. It is the best equipment for modern control of asynchronous AC motor starting and running
The frequency converter is used to change the speed of the water pump to adjust the flow and pressure of the water pump. The frequency converter generally has a closed-loop control function, which can automatically control the operation according to the pressure signal to achieve constant pressure water supply.
