Composition and principle of hydraulic pump

Component composition:
Excavator hydraulic pump is the core component of excavator walking system, which is composed of many important components to realize the conversion and transmission of hydraulic power. The following are the main components of the hydraulic pump of the excavator:
Hydraulic pump housing: The hydraulic pump housing is the housing of the hydraulic pump, which carries all the internal components and ensures the sealing and stability of the hydraulic system.
Plunger assembly: The plunger assembly in the hydraulic pump is composed of a plurality of plungers and plunger bushings, through which the plunger reciprocates in the casing to achieve the pressure conversion of hydraulic oil.
Swash plate: The swash plate in the hydraulic pump is a component fixed on the plunger assembly, and the flow and pressure changes of hydraulic oil are realized through the rotating movement of the swash plate.
Gear assembly: Gear assembly is the driving part of the hydraulic pump, composed of gears and bearings, etc., by driving the rotation of the gear, drive the work of the hydraulic pump.
Oil inlet and outlet: The oil inlet is used to introduce hydraulic oil, while the oil outlet outputs the hydraulic oil after pressure conversion to transfer power to other components of the hydraulic system.
How it works:
The working principle of excavator hydraulic pump is to convert mechanical energy into hydraulic energy through the flow and pressure conversion of hydraulic oil, and transfer it to other parts of the hydraulic system, so as to realize the power transmission of the excavator walking system. The following is the working principle of the hydraulic pump of the excavator:

Oil inlet stage: When the hydraulic pump is working, the hydraulic oil enters the plunger assembly of the hydraulic pump from the oil inlet. The plunger assembly rotates with the swash plate so that the plunger reciprocates in the plunger sleeve.
Pressure transition phase: With the reciprocating movement of the plunger, the hydraulic oil creates a pressure change between the plunger and the plunger casing. When the plunger moves from the low pressure area of the plunger casing to the high pressure area, the hydraulic oil is compressed to form the high pressure oil. Conversely, when the plunger moves from the high pressure area to the low pressure area, the hydraulic oil releases pressure.
Output stage: After pressure conversion, high-pressure oil is output from the oil outlet of the hydraulic pump and transferred to other components of the excavator hydraulic system, such as hydraulic cylinders and hydraulic motors, to realize the walking and operating actions of the excavator.
Continuous work: The hydraulic pump continuously circulates the oil intake, pressure conversion and output stages to continuously provide power for the excavator and ensure its efficient and stable operation.
The synergistic effect of the component composition and working principle of the hydraulic pump of the excavator enables the excavator to show excellent performance in the construction of the project and complete various tasks flexibly and efficiently. As a key component of excavator walking system, the stable operation of hydraulic pump is of great significance to the safety and work efficiency of excavator.


Hydraulic pump use process

Excavator hydraulic pump is one of the core components of excavator, responsible for providing power and energy to drive various movements of the machine. The correct operation of the hydraulic pump is crucial to the performance and life of the excavator.
Step 1: Check the hydraulic fluid
Before operating the hydraulic pump, first check the oil level height and quality of the hydraulic oil. Make sure that the oil level is in the right position, and check that the oil is clean and there are no impurities. If necessary, replace or add hydraulic oil in time to ensure that it is within the specified working range.

Step two: Preheat
Start the engine of the excavator and allow it to preheat for a period of time to ensure that the temperature of the hydraulic oil gradually rises to fully lubricate and protect the normal work of the hydraulic pump.

Step 3: Operate the lever
Put the excavator operating control lever in neutral position to ensure that all hydraulic control valves are in a neutral position. This will ensure that the hydraulic pump will not be subjected to excessive load when starting, helping to extend the service life of the pump.

Step 4: Start the hydraulic pump
Slowly turn the hydraulic pump switch from "off" to "On". At this time, it is necessary to carefully observe whether the hydraulic pump is operating normally and whether there is abnormal sound or vibration. If abnormal conditions are found, the pump should be stopped immediately and the cause of the problem should be checked.

Step five: Adjust the pump working pressure
According to the actual needs, gradually adjust the working pressure of the hydraulic pump. Ensure that the working pressure of the pump is within the set range to obtain the best working performance.

Step six: Observe the hydraulic system
During the operation of the hydraulic pump, always pay attention to the working state of the hydraulic system. Ensure that the hydraulic oil is kept at the appropriate temperature and pressure, and watch for signs of oil leakage. If any abnormal situation is found, check and repair it in time.

Step 7: Stop the hydraulic pump
After the end of the excavation work, the hydraulic pump switch should be turned back from the "on" position to the "off" position to stop the pump. At the same time, put the operating lever in neutral to return the hydraulic system to neutral.

Hydraulic pump of excavator is the key working part of excavator. The operation process of hydraulic pump is related to the performance and life of excavator. Through the correct hydraulic pump operation process, the safe and efficient operation of the excavator can be ensured, while extending the service life of the hydraulic pump, reducing maintenance costs and improving work efficiency. Therefore, every staff operating the excavator should be familiar with and follow the operating procedures of the hydraulic pump, so as to achieve scientific operation and careful maintenance. This will help improve work efficiency, ensure work safety and achieve better work results.
