Excavator Hydraulic Pupm Diagram

About Excavator hydraulic pupm diagram, people who have not systematically learned professional knowledge may seem to have some difficulties, let xiaobian take you a general understanding.

As shown above, The main pump is a single body with an outlet. The main pump is a variable displacement piston pump. The pump consists of a piston barrel in the pump housing(5), piston (6) and rotary swash plate (9). The oil from the hydraulic tank flows into the pump through the oil suction port (3). The oil is then drawn into the pilot pump through the inlet oil channel. The pilot pump is directly connected to the main pump. The shaft (10) is connected directly to the engine. The piston barrel (5) is splined to the shaft. When the shaft rotates, the piston barrel rotates with it. In this way, the piston (6), the slipper (8) and the retainer (7) rotate. The slipper is connected to the piston. As the shaft rotates, the retainer (7) pushes the slipper against the rotating swash plate (9). At the same time, the piston (6) on the inclined surface of the rotating swash plate rotates. As the slipper moves up the inclined plane, oil is pushed out of the piston. At the end of this stroke, the boot is aligned with the incline of the rotary swash plate. This action creates suction, which draws oil into the piston. The oil enters the pump from the hydraulic tank through the oil suction port (3), and then the oil is sucked through the inlet oil channel into the valve plate (4). The oil forced out of the piston (6) flows to the outlet (P). Oil flows to the main control valve. The pump regulator changes the Angle of the swash plate according to the flow required for machine operation. As the Angle of the tilting surface of the rotary swash plate changes, the stroke of the piston (6) changes and the pump output increases or decreases.
