The Applied Research Of Frequency Conversion Technology In Constant Pressure Water Supply System

The constant pressure water supply system fusion automation technology, the electrical machinery modern control technology and so on advanced science and technology, enhanced water supply system's stability and the water supply quality. But applies the asynchronous motor frequency conversion velocity modulation in the constant pressure water supply system, caused this system to have a finer stability and the energy conservation effect.This article take the asynchronous motor control policy, frequency changer's basic principle as well as constant pressure water supply system's theoretical knowledges and so on basic structure as a foundation, has carried on the system design to some city first surface water works' constant pressure water supply system,. has given the asynchronous motor frequency conversion technology in the constant pressure water supply system's general layout principle, and aimed at its energy conservation effect as well as the operational factor reasonable disposition has carried on the analysis, indicated the frequency conversion technology to conserve energy in the constant pressure water supply system's application reduces the row, to enhance the tremendous role which the systems operation stability, extension aspects and so on useful life of equipment and improvement working conditions got up.
