Non negative pressure water supply pump equipment

Equipment Overview:
The non negative pressure variable frequency water supply pump equipment is put into use. The water in the water supply network enters the steady flow tank, and the air inside the tank is discharged from the vacuum eliminator. After the water is filled, the vacuum eliminator automatically shuts off. When the pressure of the water supply network can meet the water demand, the system supplies water directly to the water supply network through the bypass check valve; When the pressure of the water supply network cannot meet the water demand, the system pressure signal is fed back to the variable frequency controller through a remote pressure gauge. The water pump runs and automatically adjusts the speed and constant pressure water supply according to the amount of water used. If the running water pump reaches the power frequency speed, another water pump will be started for variable frequency operation. When the water pump is supplying water, if the water volume in the water supply network is greater than the flow rate of the water pump, the system maintains normal water supply: during peak water usage, if the water volume in the water supply network is less than the flow rate of the small pump, the water in the stabilizing tank can still supply water normally as a supplementary water source. At this time, air enters the stabilizing tank through the vacuum eliminator, and the vacuum inside the tank is destroyed, ensuring that the water supply network does not generate negative pressure. After the peak water usage, the system returns to normal water supply state. When the water supply network is shut down, causing the liquid level in the stabilizing tank to continuously decrease, the liquid level detector will feedback the signal to the variable frequency controller, and the water pump will automatically stop to protect the water pump unit. When there is a low flow of water supply at night and the pressure of the tap water network cannot meet the requirements, the pressure tank can store and release energy, avoiding frequent starting of the water pump.
