Composition and principle of hydraulic pump

Hydraulic pump is an important hydraulic system component in construction machinery such as excavators, and its working principle is as follows:

Hydraulic pump input: The input end of the hydraulic pump is connected to the oil supply source of the hydraulic system, usually a hydraulic tank. The hydraulic pump draws hydraulic oil from the tank.
Oil suction port: The oil suction port of the hydraulic pump is located at the input end of the hydraulic pump and is used to draw hydraulic oil from the hydraulic tank.
Oil filter: The oil filter is usually set at the oil suction port to filter impurities and pollutants in the hydraulic oil to protect the normal operation of the hydraulic pump and hydraulic system.
Pump shaft and plunger: The hydraulic pump is provided with a pump shaft and plunger, and the rotation of the pump shaft will drive the plunger to produce reciprocating motion.
High pressure chamber and low pressure chamber: The plunger switches two chambers inside the hydraulic pump, one is a high pressure chamber and the other is a low pressure chamber.
Oil outlet: There is an oil outlet between the high pressure chamber and the low pressure chamber, which is used to control the flow direction of hydraulic oil.
Reversing valve: According to the working state of the hydraulic pump, the reversing valve controls the opening and closing of the oil outlet between the high pressure chamber and the low pressure chamber to achieve the forward and reverse of the hydraulic pump.
Hydraulic pump output end: The output end of the hydraulic pump is connected to the hydraulic cylinder or hydraulic motor of the hydraulic system through the pipeline.
Hydraulic motor: When the hydraulic oil output by the hydraulic pump enters the hydraulic motor, the hydraulic motor begins to work, converting the hydraulic energy into mechanical energy, and pushing the construction machinery such as excavators to walk or perform other actions.
The above is the basic working principle of K3V112 hydraulic pump. The hydraulic pump converts hydraulic energy into mechanical energy through continuous circulation to absorb and discharge hydraulic oil, providing powerful power support for construction machinery.



Product application range

First, intelligent technology:

Adaptive control: The future excavator hydraulic pump will be further intelligent and adopt adaptive control technology. It can adjust the output in real time according to the working condition and load of the excavator to provide more accurate hydraulic control and optimize the use of energy.
Autonomous operation: With the development of artificial intelligence technology, excavator hydraulic pumps may realize autonomous operation, sense the surrounding environment in real time through sensors and algorithms, and automatically complete work according to task requirements, improving work efficiency and safety.
Second, environmental protection and sustainable development:

Electric hydraulic pump: There may be more electric hydraulic pump technology in the future to reduce the carbon emissions and noise pollution of excavators. The electric hydraulic pump can use clean energy to drive and improve the environmental performance of the excavator.
Biohydraulic oil: Biohydraulic oil is a renewable hydraulic oil that can replace traditional mineral oil and reduce its environmental impact. Future excavator hydraulic pumps may use bio-hydraulic oil to achieve more environmentally friendly engineering construction.
Iii. Expansion of emerging areas:

Aerospace: The high performance and stability of hydraulic pumps for excavators may find new applications in the aerospace sector. It can be used in aircraft landing gear, flight control systems, etc., to improve aircraft performance and safety.
Marine engineering: The future excavator hydraulic pump may be extended to the field of Marine engineering, for seabed resource development, deep-sea exploration and other tasks, to help Marine science and resource utilization.
