Negative pressure-free water supply is a secondary water supply method that uses the residual pressure of the municipal water supply network and is related to the municipal water supply capacity. Different regions, areas and cities have different municipal water supply capacity and water supply needs. Based on many years of accumulation in the water industry, Dexi Intelligent Water Services conducts an overall analysis of the water supply and water consumption based on the water consumption and the municipal pipe network, combined with the water supply and water consumption from the municipal water intake room and the secondary pump room to the district booster, and provides overall, optimized and energy-saving solutions, water supply methods and water supply equipment applicable to different regions, areas and cities. equipment. The company has developed intelligent negative pressure water supply equipment specifically for the actual needs of secondary water supply, using integrated design of frequency conversion pump control and advanced control units to ensure intelligent and optimised operation of the units, providing a safe and reliable solution for negative pressure water supply.
