With the continuous expansion of China's urban scale, the residential area is increasing, the urban water load is also expanding, the pressure of urban tap water supply pipe network can not meet the increasing requirements of residents' water use, and the high-rise community's performance is caused by insufficient water supply pressure. The lack of water, and the non-negative pressure water supply system is widely used in secondary water supply because of its advantages of energy saving, easy maintenance, safety and sanitation without secondary pollution, and solves the problem of insufficient water supply on high floors.

The non-negative pressure and constant pressure intelligent water supply equipment directly uses the municipal pipe network as the water source to form a continuously sealed relay pressurized water supply mode. It can automatically detect the motor's actual water consumption and pressure and adjust the motor's speed (power consumption). The equipment is always in an efficient working condition. The water quality standard caused by the traditional secondary pressurized water supply system is completely avoided and various water source pollution problems are avoided. The integrated prefabricated pumping station completely maintains the water quality standard of the municipal water source and fully utilizes the pressure heat energy of the municipal water source itself. The ground has greatly exerted the energy-saving effect of frequency conversion speed regulation.

The non-negative pressure constant pressure intelligent water supply device connects the water pump to the tap water supply pipe network, and the air in the steady flow compensator is discharged from the vacuum suppressor. When the water is full, the vacuum suppressor is automatically closed. When the pressure of the water pipe network can meet the water pressure requirement, the microcomputer control system controls the water pump to enter the sleep state or enters the voltage regulation and pressure holding state by the voltage stabilization system, and the user water is directly supplied from the equipment bypass pipe; when the water pipe network When the pressure can not meet the water demand, the system gives the pump signal through the pressure sensor to start the pump variable frequency constant pressure operation. When the water pump supplies water, if the water volume of the water pipe network is greater than the water pump flow rate, the non-negative pressure water supply equipment maintains normal water supply. When the water supply peak period is less than the water pump flow rate, the water in the steady flow compensator can still be used as a supplementary water source. Normal water supply. At this time, the air enters the steady flow compensator from the vacuum suppressor, eliminating the negative pressure of the water pipe network. The steady flow regulating tank and the pipe do not generate negative pressure. After the peak period of water is used, the system pressure is greater than the protection value of the equipment. The tap water enters the steady flow compensator and the equipment continues to work normally. If the tap water supply is insufficient or the pipe network is stopped, the water level in the tank is reduced to no water, and the level controller gives a stop signal to protect the pump unit. The water pump automatically restores the water supply when the water comes in. Due to the adoption of a new type of variable frequency control technology, it has soft start, overload, short circuit, over voltage, under voltage, phase loss, over temperature and stall protection, signal alarm, self-test and fault judgment under abnormal conditions. The feed water flow rate is also automatically adjusted according to the amount of water used.
