众所周知,由于水泵是二次方率负载,其实现变频调速节能的最终效果非常可观。该作笔者主要对PLC控制变频器在恒压供水系统当中的具体应用进行了全面、深入的阐述。
As we all know, because the pump is the quadratic load, the ultimate effect of energy-saving frequency control is very impressive. The writer made a comprehensive and thorough exposition on the concrete application of PLC controlled frequency converter in the constant pressure water supply system.
