The non-negative pressure frequency conversion water supply pump equipment is put into use, the water of the water transmission pipe network enters the steady flow tank, the air in the tank is discharged from the vacuum eliminator, and the vacuum eliminator closes automatically after the water is filled. When the pressure of the water transmission pipe network can meet the requirements of water, the system directly supplies water to the water pipe network by the bypass check valve; When the pressure of the water transmission network cannot meet the requirements of water use, the pressure signal of the system is fed back to the frequency conversion controller by the remote pressure gauge. The water pump runs, and automatically adjusts the speed of constant pressure water supply according to the amount of water consumption.
Equipment overview:
The non-negative pressure frequency conversion water supply pump equipment is put into use, the water of the water transmission pipe network enters the steady flow tank, the air in the tank is discharged from the vacuum eliminator, and the vacuum eliminator closes automatically after the water is filled. When the pressure of the water transmission pipe network can meet the requirements of water, the system directly supplies water to the water pipe network by the bypass check valve; When the pressure of the water transmission network cannot meet the requirements of water use, the pressure signal of the system is fed back to the frequency conversion controller by the remote pressure gauge. The water pump runs, and automatically adjusts the speed of constant pressure water supply according to the amount of water consumption. If the running water pump reaches the power frequency speed, another water pump will be started for frequency conversion operation. If water supply pump, water pipeline network of water is greater than the pump flow, system maintain normal water supply: water peak, if the water pipe network of water less than a small amount of pump flow, steady flow tank water supplement water can still normal water supply, at this point, the air from the vacuum eliminator to steady flow tank, tank vacuum destroyed, to ensure that the water does not produce negative pressure, the water after the peak, the status back to normal water supply system. When the water transmission pipe network stops, the liquid level of the flow stabilizer tank drops continuously, the liquid level detector will feed back the signal to the frequency conversion controller, and the water pump will stop automatically to protect the water pump unit. When the water supply is small at night and the pressure of the tap water pipe network cannot meet the requirements, the pressure tank can store and release energy to avoid the frequent start of the pump.
