List of spare parts

Working principle

Oil suction process: The plunger moves backwards, the pump chamber volume increases, forming a vacuum, and the hydraulic oil in the oil tank enters the pump chamber under atmospheric pressure.

Oil pressure process: The plunger moves forward, the pump chamber volume decreases, the hydraulic oil is compressed, the pressure increases, the oil outlet valve is pushed open, and high-pressure oil enters the hydraulic system.

performance parameter

Displacement: The volume of oil discharged by the pump shaft per revolution determines the working speed and force of the excavator.

Pressure: The pressure of the oil at the pump outlet determines the working capacity of the excavator.

Rotational speed: The rotational speed of the pump shaft affects the flow rate and lifespan of the pump.

Efficiency: The ratio of output power to input power of a pump, reflecting energy loss.

Maintenance

Regularly replace hydraulic oil and filter element to keep the oil clean.

Regularly check the noise, vibration, and temperature of the hydraulic pump, and promptly address any abnormalities found.

Avoid long-term overload work to prevent hydraulic pump overheating and damage.

development trend

High pressure and high flow rate: Improve the work efficiency and operational capacity of excavators.

Intelligence: Adopting electronic control technology to achieve precise control and energy management of hydraulic pumps.

Energy saving and environmental protection: Develop hydraulic pumps with low noise, low energy consumption, and low emissions.

Main Business Model

Excavators are heavy machinery widely used in various fields such as construction, engineering, and mining. The main application areas include:

Construction engineering: Excavators are used for excavating foundation pits, cleaning sites, excavating underground facilities, foundation construction, etc.

Mining: In mines, excavators are used for mining ores, transporting materials, stripping topsoil, and crushing operations.

Water conservancy engineering: In water conservancy construction, excavators are used to excavate rivers, clear lakes, build dams and canals, etc.

In the field of agriculture, excavators are sometimes used to cultivate land, dig water channels, and construct irrigation systems in large-scale agricultural production.

Forestry: used for logging, clearing forest paths, clearing trees, and transporting timber.
