The main pump of the excavator's hydraulic pump is the core of its Hydraulic system, and the main working principle is as follows:

Excavator hydraulic pump working principle

1.Power source: the main pump is powered by a diesel engine.

2.Hydraulic pump type: usually gear pumps or piston pumps, the oil pressure into the system.

3.Oil inlet: oil from the tank is sucked in and filtered.

4.Pressure oil: oil is compressed in the pump, pressure and flow increase.

5.Output oil: High-pressure oil is delivered to the hydraulic cylinders and motors to drive the various components of the excavator.

6.Control system: The flow of oil is controlled by hydraulic valves to realize the operation of different working devices.

7.Return oil: The oil returns to the tank after use and passes through the radiator to cool down.

In short, the main pump converts mechanical energy into hydraulic energy to drive the excavator to complete the operation. For further information, please feel free to ask!
