The non negative pressure secondary water supply equipment is also called superimposed pressure water supply equipment. The water source is tap water. Make full use of the pressure of the municipal pipe network to realize the secondary water supply mode of "how much difference, how much compensation".
When the water pressure of the tap water pipe network meets the water use requirements, the equipment will automatically stop working; When the water pressure of the tap water pipe network is insufficient to meet the water demand, the equipment starts to work until it meets the water demand;
Applicable cases: energy saving and consumption reduction transformation of the user's original pressurization system.
All kinds of reclaimed water, sewage and wastewater treatment plants;
Various waterworks and water supply booster pump stations;
Constant pressure oil transportation systems such as oil pipelines, oil depots, oil pump stations and oil ports in oil fields;
The non negative pressure water supply equipment is also applicable to the production water of various industrial and mining enterprises (such as circulating cooling water, industrial boiler water supply system and other production water requiring constant pressure);
High rise buildings, residential quarters, enterprises and institutions and other living and fire water supply systems, HVAC, central air conditioning circulation and quality separation.
