Abstract：In order to resolve the disaccord of startup times of motors’ andtheir duty period,and keep the hydraulic pressure of system stable, the automaticcontrol circuit about three pumps work or standby is designed. The work principle ofthe electrocircuit and control pumps auto control is introduced particularly.Theprocess of auto circulatory of pumps is analysed.The circuit is used in fire system.The results shows that the design is reasonable.
