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.

Hydraulic pump operation method

Excavator hydraulic pump is the core component of excavator walking system, and its operation method is very important for the performance and safety of excavator.

First, check the working state of the hydraulic pump:

Before operating the hydraulic pump of the excavator, first check the working state of the hydraulic pump. Ensure that the oil level of the hydraulic oil is sufficient, and check the hydraulic oil for impurities. At the same time, observe whether the hydraulic pump has abnormal sound or oil leakage phenomenon. If there is any abnormal situation, it should be stopped and repaired immediately.

Second, start the hydraulic pump:

Before starting the hydraulic pump of the excavator, ensure that the reversing valve of the hydraulic pump is in the neutral position. Then, press the start button of the excavator, and the hydraulic pump begins to work. After the normal operation of the hydraulic pump, the reversing valve can be slowly switched to the required working state.

Third, adjust the hydraulic pump flow and pressure:

Adjust the flow and pressure of the hydraulic pump according to the specific work requirements. By operating the control valve, the output flow of the hydraulic pump can be adjusted to control the speed of the hydraulic cylinder. At the same time, according to the different working environment, adjust the working pressure of the hydraulic pump to ensure the safe and stable operation of the hydraulic system.

4. Flexible operation of excavator:

After being familiar with the operation method of the hydraulic pump, the operator can realize the flexible movement of the excavator by controlling the excavator's joystick and foot pedal. The control lever can adjust the flow rate and pressure of the hydraulic pump to realize the forward, backward, steering and other actions of the excavator. At the same time, through the operation of the foot pedal, you can control the start and stop of the hydraulic pump and speed adjustment.

5. Stop the hydraulic pump safely:

After using the hydraulic pump of the excavator, the work of the hydraulic pump should be stopped in time. First, switch the reversing valve of the hydraulic pump to the neutral position, and then press the stop button of the excavator, and the hydraulic pump stops working. After stopping the hydraulic pump, turn off the power source of the excavator in time to ensure that the hydraulic system is in a safe state.

The operation method of excavator hydraulic pump is an important link to ensure the safe operation and efficient operation of excavator. By being familiar with the working state of the hydraulic pump, starting the hydraulic pump, adjusting the flow and pressure, flexibly operating the excavator, and safely stopping the hydraulic pump, the operator can give full play to the performance of the hydraulic pump, realize the smart control of the excavator, and contribute the heart of the project to the project construction. At the same time, the rational use of hydraulic pumps can also extend the service life of hydraulic pumps, reduce maintenance costs, and ensure the efficient operation of excavators in various engineering tasks.
