The hydraulic system of construction machinery is composed of three major parts: hydraulic oil tank, hydraulic pump device and hydraulic control device. The hydraulic tank is equipped with air filter, oil filter, liquid level indicator and cleaning hole, etc.
The technology of hydraulic system
Hydraulic pump devices include different types of hydraulic pumps, drive motors and couplings between them. Hydraulic control device refers to the various valve components and their connections that make up the hydraulic system.
Advantages of hydraulic system
The hydraulic system has the following advantages compared to other transmission systems:
1. Large transmission torque: The hydraulic system transmits torque through the pressure of the liquid and can achieve high-power transmission.
2. Long transmission distance: The hydraulic system can transmit liquid through long-distance pipelines and is suitable for long-distance force transmission.
3. Smooth transmission: Through the transmission of liquid, the hydraulic system can achieve smooth transmission of force and reduce vibration and impact.
4. High control accuracy: The hydraulic system can achieve precise control of parameters such as force, speed, and position through the control of hydraulic valves.
5. High reliability: Since the hydraulic system has no friction parts, it has high reliability and lifespan.
