Variable Frequency Conversion Constant Pressure Water Supply System

 



1 Products information:
1 haracteristics:Saves in capital and running [energy] costs.Reduces maintenance related costs and downtime.Improves the "GREEN" rating of the project, where installed.
2 Operational principle:
The water enter stainless steel steady flow tank, the tank air is flowing out from the vacuum controller,then the vacuum controller automatically closed.
The water supply equipment directly supply water to water pipe network from bypass check valve when
Tap water can meet the requirements of water pressure and water quantity;

When the pressure in pipeline networks of tap water can not meet the water requirement,the system give a signal to pump, then the pump works.When the pump supply water, the system keep supplying water if the water quantity in pipeline network of tap water is more than pump capacity.

During the peak time of water use,if the water quantity in the pipeline network of tap water is less than the pump capacity,the water in the stainless steel steady flow tank can supply water normally as supplementaty water source, at this time, the air enter into the stainless steel steady flow tank through vacuum control suppressor, eliminate the negative pressure in the pipeline network of tap water;And after the peak time of water use, the system recover the normal condition.If the tap water is not enough or the pipeline network stop supply water and result in the water level in regulating tank falls ,the liquid level controller send signal to water outlet pump in order to protect pump unit.

You can use small expansion tank to supply water at night or it is need to supply small quantity water to prevent the pump from start frequently.
