When the non-negative pressure frequency conversion water supply equipment is put into use, the water from the tap water network enters the steady flow tank, the air in the tank is discharged from the vacuum eliminator, and the vacuum eliminator is automatically closed after the water is filled. When the pressure of the tap water network can meet the requirements of water use, the system is supplied directly to the water network by the bypass check valve; when the pressure of the tap water network cannot meet the requirements of water use, the system pressure signal is fed back to the frequency controller by the remote pressure meter, and the pump runs and automatically adjusts the speed of constant pressure water supply according to the size of the water consumption; if the running pump reaches the working frequency speed, another pump is started to run with frequency. When the water is supplied by the pump, if the water volume of the tap water network is greater than the flow of the pump, the system will maintain normal water supply: at the peak of water consumption, if the water volume of the tap water network is smaller than the flow of the small pump, the water in the flow stabilization tank can still provide normal water supply as a supplementary water source. After the peak of water consumption, the system returns to normal water supply. When the water supply network stops, causing the liquid level of the stabilized tank to drop, the liquid level detector will feedback the signal to the frequency controller, and the pump will stop automatically to protect the pump unit. When the water supply is small at night and the pressure of the water pipe network cannot meet the requirements, the air pressure tank can store and release energy to avoid frequent pump start.
