Maintenance Guide for Loader Hydraulic Pump Accessories: Key Points and Methods

As a commonly used mechanical equipment in engineering construction, the normal operation of the hydraulic pump of the loader is crucial. The good condition of the hydraulic pump accessories is the basis for ensuring the efficient operation of the hydraulic pump. Scientific and reasonable maintenance can extend the service life of the accessories and reduce the probability of equipment failure. The following is a detailed description of the maintenance of the hydraulic pump accessories of the loader.

1. The importance of maintenance of hydraulic pump accessories

The hydraulic pump is the core component of the loader hydraulic system, and the performance of its accessories directly affects the working efficiency and stability of the entire hydraulic system. If the accessories are worn or damaged, it will not only cause problems such as unstable output pressure and insufficient flow of the hydraulic pump, but may also cause failure of the entire loader, affect the progress of the project, and increase maintenance costs. Therefore, regular maintenance of hydraulic pump accessories is a key link to ensure the normal operation of the loader.

Key points:

1. The hydraulic pump is the core of the loader hydraulic system, and the performance of the accessories affects the efficiency and stability of the system.

2. Accessory problems can cause failures of the hydraulic pump and loader, increase costs and affect progress.

3. Regular maintenance is the key to ensuring the normal operation of the loader.

2. Main accessories and maintenance methods

1. Pump body: The pump body is the main structure of the hydraulic pump. Its appearance should be checked regularly for cracks, wear or leakage. During operation, the pump body should be protected from strong impact and vibration to prevent damage to the pump body due to external forces. In addition, attention should be paid to keeping the pump body clean to prevent dust, impurities, etc. from entering the pump body and affecting its normal operation. Clean the oil and debris on the surface of the pump body regularly, and use a special cleaning agent to wipe it.

2. Plunger and cylinder: The plunger and cylinder are key components for the hydraulic pump to achieve energy conversion. The wear of the plunger and cylinder should be checked regularly, which can be judged by measuring their matching clearance. If the clearance exceeds the specified value, the accessories should be replaced in time. During use, ensure the cleanliness of the hydraulic oil to prevent impurities from entering between the plunger and the cylinder body and aggravating wear. At the same time, the hydraulic oil should be replaced according to the prescribed cycle to ensure its good lubrication performance.

3. Distribution plate: The function of the distribution plate is to control the flow direction and flow of the hydraulic oil. During maintenance, check whether the surface of the distribution plate has scratches, wear or burns. If any problems are found, they should be repaired or replaced in time. In addition, pay attention to the matching accuracy of the distribution plate and other components to ensure its sealing during operation. Clean the oil stains and impurities on the distribution plate regularly to prevent blockage of the oil circuit.

4. Oil seals and seals: Oil seals and seals are important components to prevent hydraulic oil leakage. Check the aging and wear of oil seals and seals regularly. If they are damaged or deformed, they should be replaced immediately. When installing oil seals and seals, pay attention to their installation direction and method to ensure the sealing effect. At the same time, avoid excessive stretching or extrusion of oil seals and seals to avoid damage.

5. Filter: The function of the filter is to filter impurities in the hydraulic oil and ensure the cleanliness of the hydraulic oil. The filter element should be replaced regularly, generally in accordance with the requirements of the equipment instruction manual. When replacing the filter element, pay attention to cleaning the filter housing and connecting pipes to prevent impurities from entering the hydraulic system. In addition, the filter should be checked regularly for blockage. If the filter is found to be seriously blocked, it should be cleaned or replaced in time.

Key points:

1. Pump body: Check the appearance, avoid impact vibration, and keep it clean.

2. Plunger and cylinder: Check wear, ensure oil cleanliness, and change oil regularly.

3. Distribution plate: Check the surface, pay attention to the matching accuracy, and clean impurities.

4. Oil seals and seals: Check aging and wear, install correctly, and avoid excessive stretching and extrusion.

5. Filter: Change the filter element regularly, clean the housing and pipeline, and check the blockage.

III. Maintenance precautions

1. Follow the operating procedures: When maintaining the loader hydraulic pump accessories, strictly follow the equipment's instruction manual and operating procedures. Avoid damage to accessories or safety accidents due to improper operation.

2. Use qualified accessories: When replacing hydraulic pump accessories, choose accessories with qualified quality and matching specifications. Inferior accessories not only have a short service life, but may also affect the normal operation of the hydraulic pump and even cause serious failures.

3. Regular maintenance and inspection: Establish a regular maintenance and inspection system, and conduct comprehensive inspection and maintenance of hydraulic pump accessories according to the prescribed cycle. Discover and deal with potential problems in a timely manner, and eliminate faults in the bud.

4. Pay attention to the working environment: The working environment of the loader is often harsh, and attention should be paid to protecting the hydraulic pump accessories from dust, moisture, high temperature and other factors. When working in harsh environments, appropriate protective measures should be taken, such as adding protective covers and using appropriate hydraulic oil.

Key points:

1. Operate according to regulations to avoid damage to accessories due to improper operation.

2. Use qualified accessories to prevent inferior accessories from affecting work.

3. Regularly inspect and maintain, and discover and deal with problems early.

4. Pay attention to the working environment and take protective measures.

In short, the maintenance of loader hydraulic pump accessories is a meticulous and important task. Only by fully realizing the importance of maintenance and mastering the correct maintenance methods and precautions can we ensure that the hydraulic pump accessories are always in good working condition, provide strong guarantees for the efficient operation of the loader, and thus improve the efficiency and quality of engineering construction.
