The working principle of kobelco hydraulic pump：
The hydraulic system of the excavator consists of five parts: power components, control and adjustment components, actuators, auxiliary components and hydraulic oil. The working process of the hydraulic system of the excavator is as follows: the diesel engine outputs power through the coupling, the kobelco hydraulic pump absorbs oil from the hydraulic oil tank, the working oil is output through the working pump, and the pilot oil is output through the pilot pump. After the driver manipulates the pilot handle, the pilot valve is opened, and the pilot oil pushes The main control valve spool, the working oil enters the motor or the oil cylinder, and realizes the expansion and contraction of the oil cylinder of the rotating, walking and working device.
