Is there any way to reduce the frequency of hydraulic excavator failures in coal mines（haoyun）

Does the editor of Shandong Haoyun Heavy Industry Machinery Co., Ltd. have any methods to reduce the frequency of hydraulic excavator failures in coal mines? Please do the following.

Here are some methods to reduce the frequency of hydraulic excavator failures in coal mines:

1、 Daily maintenance

1. Equipment inspection: Check the appearance, bolts, pins, oil cylinders, slewing supports, and walking devices of the equipment daily to check for cracks, deformations, oil leaks, and other issues, and promptly address any abnormalities found.
2. Oil management: Regularly check the oil level and quality of hydraulic oil and gear oil, replace them according to the prescribed cycle, and pay attention to selecting suitable oil products and ensuring that the oil is clean and free of impurities.
3. Filter maintenance: Various filter elements should be replaced regularly according to requirements, and during replacement, check for any abnormalities such as metal particles. Use pure filter elements that comply with machine regulations.

2、 Correct operation

1. Standardize the use of the breaking hammer: When using the breaking hammer, it should be gradually moved forward and broken in stages, with a strike angle of less than 90 degrees. Choose an appropriate strike point to prevent empty strikes and avoid equipment damage caused by improper operation.
2. Avoid overload operation: Haoyun Heavy Industry strictly operates according to the rated load of the equipment, does not operate beyond the load, and prevents engine, hydraulic system and other components from malfunctioning due to overload.
3. Reasonably control the operating speed: Based on the operating conditions and equipment performance, reasonably control the operating speed of the excavator, avoid long-term high-speed or low-speed operation, and reduce equipment wear and tear.

3、 Environmental management

1. Keep the working environment clean: Try to avoid working in harsh environments such as muddy, dusty, and highly corrosive places. If it is unavoidable, clean the equipment promptly after work to prevent impurities from entering the interior of the equipment.
2. Pay attention to temperature effects: When working in high temperature environments, pay attention to the heat dissipation of equipment to prevent overheating of engines, hydraulic systems, etc; In low-temperature environments, preheating and insulation measures should be taken to ensure the normal start-up and operation of the equipment.

4、 Regular maintenance

1. Develop maintenance plan: Haoyun Heavy Industry will develop a detailed regular maintenance plan based on the usage of the equipment, and conduct comprehensive inspections and maintenance of the equipment.
2. Professional maintenance personnel operation: Maintenance work should be carried out by professional maintenance personnel to ensure the quality and safety of maintenance.
3. Timely replacement of worn parts: During the maintenance process, if severely worn or damaged parts are found, they should be replaced in a timely manner to avoid larger problems caused by component failures.
