With the improvement of people's living standards, more and more people like to take a bath in a large public bath center or a bath facility near their home, making the bath business popular. At the same time, this also puts forward higher requirements for the stability of water volume and water temperature control in the water supply system of the bath.

During the operation of VFD for controlling cold and hot water pump, pipe pressure is measured by pressure gauge and fed back to the VFD to determine whether the pressure is complied to the required value. After being calculated by PID, the output frequency is changed for the adjustment of pump speed, enabling the actual pressure close to the required pressure and providing the pipeline with constant pressure.
