Excavator pump

First, the basic definition of an Excavator Pump

Excavator Pump is an important part of the hydraulic system of the excavator, which is responsible for providing hydraulic power for various actions of the excavator, and is one of the key components for the excavator to work properly.

Types of Second, Excavator Pumps and how they work

1. Type: There are various types of excavator pumps, including gear pumps, piston pumps, pilot pumps, etc. Each pump has its specific structure and working principle, which is suitable for different excavator models and working scenarios.

2. Gear pump: The pressure difference is formed by the meshing of two gears to each other, so as to suck in and discharge the liquid. It has a simple structure, small size, and light weight, but it is noisy.

3. Piston pump: The reciprocating motion of the plunger in the cylinder block is used to generate a pressure difference to realize the suction and discharge of liquid. Piston pumps have the advantages of high pressure and stable flow, but the structure is relatively complex.

4. Pilot pump: It is mainly used to control various valves and actions of the excavator, and its working principle is to push the large flow of low-pressure oil through a small flow of high-pressure oil to achieve precise control of the excavator.

5. Working principle: The working principle of the excavator pump is mainly based on the liquid pressure difference and flow control. When the pump is working, it sucks the liquid out of the low-pressure area through a specific mechanism like gears, plungers, etc., and discharges it in the high-pressure area. In this process, the pressure of the liquid can be significantly increased, which provides sufficient power for the excavator's various movements.

Third, the application area of Excavator Pump

1. Excavator pumps are widely used in various construction machinery, especially heavy equipment such as excavators, loaders, cranes, etc.

2. In these equipment, the excavator pump is responsible for providing hydraulic power for various actions (such as rotating, lifting, digging, etc.) so that the equipment can work normally.

3. In addition, excavator pumps are also used in some special hydraulic systems, such as the steering gear of ships, the hydraulic transmission system of cranes, etc.

Fourth, Excavator Pump Maintenance & Maintenance

1. Regular inspection: Regularly inspect the excavator pump, including checking the tightness of the pump, the wear of the bearing, the meshing of the gear, etc.

2. Cleaning and replacement: Regularly clean the impurities and particles in the suction pipe and filter of the pump to ensure the normal suction and discharge of the pump. For parts that have been worn or damaged (such as seals, bearings, etc.), they should be replaced in time to avoid failure.

3. Adjustment and lubrication: According to the wear and tear of the pump, the gap of the gear is adjusted appropriately to ensure good sealing performance and flow output. At the same time, the bearings and gears of the pump are lubricated regularly to reduce wear and friction.

4. Professional maintenance: If the excavator pump is faulty or needs to be repaired, you should seek the help of professional maintenance personnel. They have rich experience and professional skills, and are able to accurately determine the cause of failure and carry out effective repairs.
