| Abstract: | Instead of AC inverter speed regulation,the flow/current proportional controller was used as the core part of the high pressure water supply system. With automatic PLC controlling main frequency water pump unit, the disadvantageous harmonic wave, flutter, the depressed pressure,water hammer effects caused by the inverter will be eliminated, and the purposes of stabilizing water supply pressure, conserving the power supply and improving the system reliability were obtained. |
