    Tap water non-negative pressure water supply is a new type of water supply method that can superimpose the existing pressure of the municipal pipe network to achieve energy-saving effects. It can increase the pressure based on the original pressure of tap water (that is, superimpose the existing water pressure of tap water. For example, if the tap water inlet has a pressure of 3 kilograms, then the non-negative pressure water supply equipment will increase the pressure based on the 3 kilograms), which greatly saves electric energy. The equipment operates automatically with variable frequency, supplying as much water as residents use, and automatically stops when there is no water demand, which is very convenient.

    The tap water non negative pressure water supply equipment is a new type of water supply equipment developed and produced by Changsha Zhongying Water Supply Equipment Co., Ltd. It is mainly used in residential buildings, high-rise buildings, residential areas, enterprises and institutions, various types of water plants, water supply booster pump stations and other places. Non negative pressure water supply equipment is a water supply device that is directly connected to the municipal water supply network by a water supply unit, and pressurizes the water supply based on the pressure of the municipal water supply network to meet the high-efficiency and energy-saving water use requirements of users. The core 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 pipeline network, and achieve safe, reliable, stable, and continuous water supply without affecting nearby users' water use.
