hydraulic pump of excavator

The function of a hydraulic pump, in general, is to generate flow to transfer fluids in a hydraulic system. Here’s how it typically operates:

1. Fluid Intake: The hydraulic pump draws in hydraulic fluid from a reservoir or tank. This fluid is typically oil-based and is necessary for the transmission of power within the hydraulic system.

2. Mechanical Action: The pump uses mechanical action, often driven by an engine, motor, or other power source, to create a vacuum or low-pressure zone within the pump chamber. This action causes the hydraulic fluid to be drawn into the pump from the reservoir.

3. Fluid Pressurization: Once the fluid is drawn into the pump, it is pressurized. The pump applies force to the fluid, increasing its pressure. This pressurized fluid is then ready to be used to perform work within the hydraulic system.

4. Fluid Output: The pressurized fluid is then directed out of the pump and into the hydraulic system. It travels through hydraulic lines or hoses to various components such as cylinders, motors, or actuators.

5. Power Transmission: The pressurized fluid acts upon pistons, cylinders, or other components within the hydraulic system, transmitting force and enabling the system to perform mechanical work. This work can include lifting heavy loads, moving machinery, or powering various types of equipment.

6. Cycle Continuation: The hydraulic pump continuously cycles, drawing in fluid, pressurizing it, and delivering it to the hydraulic system as needed to maintain operation.

In summary, the primary function of a hydraulic pump is to create flow and generate pressure within a hydraulic system, allowing it to transmit power efficiently and perform various mechanical tasks.
