| Abstract: | This article introduces a frequency- converting ＆ speed-regulating water supply system with constant pressure, in which a frequency converter ATV61 is used for driving two variable pumps controlled by integrated PID adjustor and system feedback signal is provided by pressure sensor. The system can be able to regulate automatically the pump numbers and their speed. The water pump spelling function and multi-variable pump function can avoid variable pump corrosion because of long term idle and extending the system life. |
