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.
