| Abstract: | This paper investigates the problem of design and renovation applications for constant pressure frequency conversion water supply system of variable flow based on PLC and inverter. The system under consideration is able to adjust pump the running status in view of pipe network pressure automatic, and the main circuit wiring diagrams and main program flow chart are designed. The designed water pumps can achieve automatically start and stop, automatic control run, stepless pressure adjustment, and truly a water use and the water supply of thedynamic balance. It optimizes the running characteristics of the considered system and effectively saves the energy, so as to guarantee constant pressure frequency conversion water supply. |
