摘  要：水泵运行电费是一笔不小的费用，从节能方面考虑，在既满足目前生产的条件下可进行变频改造。变频恒压供水控制系统通过测量的管网压力，经变频器的内置PID调节器运算后，自动调节输出频率，实现管网的恒压供水。 关键词：设备改造；恒压供水；变频调速 Abstract: Water pump running electricity is not a small cost, from the aspect of energy conservation, in both meet the current production conditions can be carried out frequency conversion.
