| Abstract: | The main circuit and control circuit of water supply system of multi pump with constant pressure and varible flow in the highrise buildings were introduced. The automatic increase or decrease of pumps and speed regulation are carried out by use of the discrimination of multi pump duty in the control system. A practical example using above working principle was described. The procedure design of automatic increase or decrease of pumps with PLC control was given. |
