excavator hydraulic pump
Excavators are a common type of construction machinery and equipment widely used in earthwork excavation, transportation, loading and other engineering operations. The hydraulic pump is one of the core components of the excavator, responsible for providing stable hydraulic power. So, how does the excavator hydraulic pump work? Now let’s have a detailed understanding of the working principle of the excavator hydraulic pump.
The excavator hydraulic pump mainly consists of the hydraulic pump body, transmission shaft, coupling, and pump control system. Its working principle is to convert mechanical energy into hydraulic energy and transmit it to other hydraulic actuators through the hydraulic system to achieve the action of the excavator.

The hydraulic pump body is the core component of the excavator hydraulic pump, usually using a gear pump or a plunger pump.There are a pair of gears or plungers that mesh with each other inside the hydraulic pump body, forming a certain volume inside the pump body. When the transmission shaft of the hydraulic pump rotates, the gear or plunger rotates accordingly, thereby changing the volume of the pump chamber.
When the volume of the pump chamber increases, the pressure inside the pump decreases, and hydraulic oil enters the pump chamber through the suction port; When the volume of the pump chamber decreases, the pressure inside the pump increases, and hydraulic oil flows out of the pump chamber through the pressure port. Through this working principle, the hydraulic pump can continuously suck in and discharge hydraulic oil, forming stable hydraulic energy.
The hydraulic pump needs to be linked with other systems during operation, which requires the action of the transmission shaft and coupling. The transmission shaft transfers the power of the engine to the hydraulic pump, causing it to rotate; The coupling connects the hydraulic pump to the transmission shaft to ensure their synchronous operation. The control system of the hydraulic pump is responsible for controlling the start, stop, and working pressure parameters of the hydraulic pump. When the excavator needs to work, the control system will send a signal to the hydraulic pump to start and provide the corresponding working pressure.
When the excavator does not need to work, the control system will stop the operation of the hydraulic pump to save energy. In general, the working principle of excavator hydraulic pump is to convert mechanical energy into hydraulic energy through the hydraulic pump body, and transmit it to other hydraulic actuators through the hydraulic system to achieve the action of the excavator.
The operation of hydraulic pumps requires the coordination of the transmission shaft and coupling, and the control system controls its start, stop, and working pressure parameters. The working principle of the excavator hydraulic pump is simple, but it is the key to the normal operation of the excavator. Only by ensuring the normal operation of the hydraulic pump can the efficiency and performance of the excavator be improved. Therefore, in the operation and maintenance process of excavators, it is necessary to have a clear understanding of the working principle of hydraulic pumps and carry out timely maintenance and upkeep to ensure the normal operation of excavators.
