Product Overview
The JSWG pipe network stacked water supply method eliminates the need for reservoirs in traditional water supply methods, saves one-time investment in building water supply systems, and makes the system from the water supply plant to the user's faucet a closed system, avoiding secondary pollution and directly utilizing the pressure of the municipal pipe network.
Shanghai Jingshui Pump Industry has developed a new generation of JSWG series pipe network pressure equipment based on the original variable frequency water supply. It consists of a dedicated water pump, an intelligent variable frequency control cabinet, a steady flow compensation tank, a negative pressure balancing device, and a stabilizing tank. It is a new type of electromechanical integrated equipment that combines computer technology, variable frequency technology, and motor pumps to meet the requirements of urban water supply pipe networks. When pumping water, it does not generate negative pressure and has certain regulation and storage capabilities. During peak periods, it continuously supplies water. The microcomputer controlled variable frequency pump operates at a constant speed, utilizing the original pressure energy of tap water to ensure that the user's required pressure is constant.
