The water supply is directly superposed on the basis of the municipal pipe network pressure, so that the energy is saved, and the water supply system has the advantages of full sealing, no pollution, small occupied area, rapidness in installation, reliability in operation, convenience in maintenance and the like.

When the water pump supplies water, if the water quantity of the tap water pipe network is larger than the flow of the water pump, the system keeps normal water supply, when the water consumption peak is reached, if the water quantity of the tap water pipe network is smaller than the flow of the small pump, the water in the steady flow tank can still supply water normally as a supplementary water source, at the moment, the air enters the steady flow tank from the vacuum eliminator, the vacuum in the tank is damaged, the tap water pipe network is ensured not to generate negative pressure, and after the water consumption peak is passed, the system is restored to a normal water supply state. When the tap water pipe network cuts off water, the liquid level of the steady flow tank is continuously reduced, the liquid level detector feeds back a signal to the variable frequency controller, and the water pump is automatically stopped to protect the water pump unit. When the water supply is carried out at night at a small flow and the pressure of a tap water pipe network cannot meet the requirement, the air pressure tank can store and release energy, so that the frequent starting of a water pump is avoided.

The intelligent frequency conversion water supply equipment has core variable flow rate and frequency conversion technology and microcomputer control technology. The speed of the water pump unit is regulated, and the water supply pressure of the water supply flow is timely changed according to the requirement of a pipe network system, so that the water use requirement is fully met. The water supply equipment is required to be provided with equipment such as a water tower, a high-level water tank and the like and valve adjusting measures, the inherent water supply flow and pressure change of the water supply equipment have large influence, and the energy waste is large.
