Two types
Gear pump: With a simple structure, low cost, and strong anti pollution ability, but with large flow pulsation and high noise, it is mostly used in small excavators or auxiliary systems.
Piston pump: with complex structure and high cost, but high working pressure, large flow rate, high efficiency, and high control accuracy, it is widely used in medium and large excavators.
 
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.
