Excavator Hydraulic Pump
hydraulic pump of an excavator is the core component of the hydraulic system of an excavator. It is responsible for converting the mechanical energy of the engine into hydraulic energy to drive various actions of the excavator. The hydraulic pump is usually driven by the engine, sucking oil from the hydraulic oil tank, forming pressurized oil and sending it to the actuators, such as hydraulic cylinders and hydraulic motors, to realize various functions of the excavator.

Type and structure
There are two main types of hydraulic pumps commonly used in excavators: gear pumps and plunger pumps. Gear pumps change the volume of liquid by rotating two meshing gears. They are suitable for low-precision, medium- and low-pressure control. They have the advantages of simple structure, convenient manufacturing, and low cost. They are often used in pilot systems.3. Plunger pumps change the volume of liquid by the reciprocating motion of the plunger in the cylinder. They are suitable for high-pressure and high-flow situations and are often used in main pump systems.
Working principle
The working principle of the hydraulic pump is to convert mechanical energy into hydraulic energy. The engine drives the hydraulic pump to rotate, and the pump sucks oil from the hydraulic oil tank. The volume change of the pump generates pressure oil, which is then sent to actuators such as hydraulic cylinders and hydraulic motors through pipelines to drive the excavator to complete various actions.
