基于PID控制的恒压变频供水系统

The Water Supply System of Constant Pressure and Frequency Convertion Based on PID Control

随着我国经济与社会的高速发展,无论是工业用水或者居民生活用水对供水质量和供水系统可靠性的要求都在不断提高,因此采用先进的自动化控制技术来设计高效节能、自动可靠的供水系统成为必然趋势。本文从技术可靠和经济实用角度综合考虑,采取PLC和变频器设计了基于PID控制的自动恒压供水系统。

With the rapid development of economy and society, the requirements for reliability of water supply quality and water supply system have been continuously enhanced for both industrial water and domestic water, so it is an inevitable tendency to design one kind of water supply system with the help of advanced technique of automation and control, which is highly reliable and saves on energy well. PLC and the frequency converter were adopted to design an automatic constant pressure water supply system based on the PID control.
