What is the difference between the front and rear pumps of the excavator hydraulic pump? The structure size of the front and rear pumps is quite the same except for the different structure of the valve plate. In practice, the front pump mainly supplies the rod, slewing, left walking and arm feeding, and the rear pump mainly supplies the bucket, the boom and the right to provide fuel. Therefore, under the actual machine, the bidirectional action of the bucket rod, the lifting of the boom and the excavation of the bucket are supplied by two pumps.

The hydraulic pump is the power component of the hydraulic system, which is driven by the engine or motor, inhaling oil from the hydraulic tank to form a component of the pressure oil discharged and sent to the actuator. According to the structure, the hydraulic pump is divided into gear pump, plunger pump, vane pump and screw pump.
