Energy-saving Reconstruction of Constant Pressure Water Supply by Converter

This paper introduces the working principle of piped water supply and the converter, as well as the theoretic analysis on constant pressure and changeable flow supply, which results in the achievement of water supply under different pressure. The system efficiency proves to be improved after the energy saving reconstruction of constant pressure water supply converter with higher stability and lower cost according to the experiences conducted by factories.
