BPQ water supply equipment mainly consists of a pressurization system, a detection system, basic configurations and an intelligent control system, etc. By pressurizing water supply and stabilizing the water outlet pressure, it addresses the demand for insufficient water supply pressure. When the frequency conversion water supply equipment is in operation, the detection control, control system and pressurization system work together. By changing the rotational speed of the water pump, the flow and pressure are adjusted to keep the pressure in the water outlet pipeline within a certain range, thereby achieving the water supply requirements of the equipment in an energy-efficient manner. The main features of the frequency conversion water supply equipment include protecting the pressure of the water supply network, energy conservation, safety, environmental protection and low noise.
