What are the new methods for maintenance and upkeep of tunnel repair machines used in coal mines（haoyun）

The editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. will discuss the new methods for maintenance and upkeep of tunnel repair machines used in coal mines.

Here are some new maintenance methods for coal mine tunnel repair machines:

1、 Daily maintenance

1. Check the appearance of the equipment: Before and after each shift, carefully inspect the body, working arm, tracks, and other parts of the coal mine tunnel repair machine for deformation, cracks, wear, and other issues, and promptly identify and address any problems.
2. Cleaning equipment: Regularly clean the equipment to remove surface debris such as coal dust and soil, and prevent debris from entering the interior of the equipment and affecting its performance.
3. Check the hydraulic system: Check the oil level and quality of the hydraulic oil to ensure that it is within the specified oil level range and that the oil quality is clean and free of impurities. At the same time, check whether there is any leakage in the hydraulic system, and replace the seals in a timely manner if there is any leakage.
4. Check the electrical system: Check whether the wiring of electrical equipment is loose or damaged, whether the electrical components are working properly, and ensure the safety and reliability of the electrical system.
5. Check the working device: Check whether the connection parts of the working arm, bucket, breaking hammer and other working devices are loose, and whether the wear of the working device exceeds the specified value. If there are any problems, they should be replaced or repaired in a timely manner.

2、 Regular maintenance

1. Replace hydraulic oil and filter element: Haoyun Heavy Industry suggests that hydraulic oil and filter element should be replaced regularly according to the usage of the equipment and the degree of contamination of the hydraulic oil. It is generally recommended to replace them every 3-6 months.
2. Check and adjust the tracks: Haoyun Heavy Industry reminds that the tension and wear of the tracks should be checked regularly. If necessary, adjust the tension of the tracks or replace them in a timely manner.
3. Inspection and maintenance of working devices: Haoyun Heavy Industry reminds that regular inspection and maintenance of working devices such as working arms, buckets, and breakers should be carried out, including replacing worn parts and checking the lubrication of the working devices.
4. Inspection and maintenance of electrical system: Haoyun Heavy Industry reminds that regular inspection and maintenance of the electrical system should be carried out, including checking the insulation resistance, grounding resistance, etc. of electrical equipment, to ensure the safety and reliability of the electrical system.

3、 Fault diagnosis and maintenance

1. Fault diagnosis: Utilizing advanced fault diagnosis techniques and equipment, such as fault diagnosis instruments, sensors, etc., to quickly and accurately diagnose equipment faults and improve maintenance efficiency.
2. Maintenance method: Advanced maintenance techniques and processes such as welding, spraying, laser repair, etc. are used to repair the faulty parts of the equipment, ensuring that the performance of the repaired equipment meets or exceeds that of the original equipment.
3. Maintenance records and analysis: Establish a comprehensive maintenance record and analysis system to record and analyze the maintenance status of equipment, summarize the rules of fault occurrence and maintenance experience, and provide reference for equipment maintenance.
