EX220-3 type excavator is a small crawler excavator produced by Japan＇s Hitachi company. It is composed by three parts,which are the work device,the upper turntable and a walking device. The discordant combined operation of this excavator is a typical problem of flow distribution control system. In this paper, the author presents a detailed analysis to the theory of machine actuator flow distribution control system and its fault diagnosis and troubleshooting method,in order to play a guiding role in the fault diagnosis of discordant combined operation.
