变频恒压供水控制仪的研制

Development of A Water Supply Controller with Frequency Conversion and Constant Pressure

采用变频器的恒压供水控制系统的主要优点是节约能源。这种控制系统必将取代传统的依靠调节回流量的恒压控制系统。它的响应速度更快、超调量更小、系统更平稳。本控制仪有三种工作模式 :单泵工作模式 。

The main advantage for constant pressure water supply control system with frequency converter is energy saving. This new control system will completely replace the traditional control system based on inverse flow adjustment. The response of this new control system is faster, its overshoot is smaller, and its pressure′s stability is higher. The new system possesses three kinds of operation modes, including single pump mode, double pump timing switching mode and double pump complement mode.
