变频器在恒压供水控制系统中的应用

Inverter in the Constant Pressure Water Supply Control System

变频调速恒压供水设备使我国供水行业的技术装备水平经历了一次飞跃,实现水泵电机无级调速,可根据用水量的变化自动调节系统的运行参数,保持水压恒定以满足用水要求。本文阐述了变频恒压供水系统的构成及原理,给出了变频器、PLC等选型。

Frequency control constant pressure water supply equipment made a leap of the technical equipment of the water supply industry, realizing stepless speed regulation of pump motor, can automatically adjust the operating parameters of the system according to changes in water, keeping constant pressure to meet the water requirements. This paper describes the constitute and principle of constant pressure water supply control system and show some models of inverter and PLC.
