| Abstract: | As to the constant pressure water-supplying system,introduced the principle of constant pressure water-supply by frequency control using PLC, designed the automation switch pump program and give out the PLC ladder chart. Long time operation have proved that the software has reliable operation,better portability,and has been wide used in frequency variable rebuilding of water pumps and air pumps. |
