Introduction of Non-negative Pressure Water Supply Equipment

The non negative pressure water supply equipment is a secondary pressurized water supply equipment that the pressurized water supply unit is directly connected to the municipal water supply pipe network, and the water supply is cascaded and superposed on the basis of the residual pressure of the municipal pipe network to ensure that the pressure of the municipal pipe network is not less than the set protection pressure (it can be zero pressure of the relative pressure, and it is called negative pressure when it is less than zero pressure).The core of the pipe network superpressure (no negative pressure) water supply equipment is how to prevent negative pressure during the operation of the secondary pressurized water supply system, eliminate the impact of unit operation on the municipal pipe network, and achieve safe, reliable, stable and continuous water supply without affecting the water consumption of nearby users.Non negative pressure water supply equipment is also known as pipe network superpressure water supply equipment. At present, there are mainly tank type non negative pressure water supply equipment and box type non negative pressure water supply equipment in the market.

Advantages:

Easy maintenance.

Save operation cost.

Maintain constant pressure.

Power failure without water supply.

Make full use of the pressure of municipal pipe network, and greatly save energy.

Avoid secondary pollution of water.

Save floor space.

Save investment.

Disadvantages:

Non negative pressure water supply has certain disadvantages. Because there is no water tank for non negative pressure water supply, although it can store water, the amount is very small. Once the municipal pipe network stops water, users will soon run out of water. Therefore, when selecting non negative pressure water supply, box type non negative pressure water supply equipment can also be considered. The stainless steel assembled water tank added on the basis of non negative pressure water supply unit can provide reserves from several to thousands of cubic meters, which has met the different needs of customers.
