The oil leakage of the Raymond mill main engine not only wastes resources and pollutes the environment, but also aggravates equipment wear, affects production efficiency, and increases maintenance costs. Therefore, it is crucial to understand the causes of oil leakage and master maintenance methods.

Failure of the sealing parts of the Raymond mill main engine

Cause: The sealing parts are used to prevent the leakage of lubricating oil. However, they will age after long - term operation, and high temperatures will accelerate the aging process, resulting in gaps in the sealing surface and the leakage of lubricating oil. If not maintained in a timely manner, it may lead to severe wear of the grinding rolls.

Maintenance method: Operators should conduct regular inspections. Once aging, hardening, or damage is detected, new suitable sealing parts should be replaced immediately.

The bolts connecting the main unit of the Raymond mill are loose

Cause: The vibration generated during the operation of the Raymond mill will affect the bolts. The thermal expansion and contraction effect also reduces the tightness of the bolt connections, leading to looseness. For example, in a building materials enterprise, due to the uneven factory floor and large temperature difference between day and night, the bolt connections became loose and oil leakage occurred.

Maintenance method: Conduct a comprehensive inspection of the bolts, use appropriate tools to tighten them according to the specified torque value. If necessary, use anti-loosening washers or thread locking agents.

Oil seal damage

Cause: Long - term use of the oil seal can cause wear, and impurities in the lubricating oil can exacerbate this wear. Improper installation can also lead to oil seal damage.

Maintenance method: When the oil seal is found to be damaged or leaking, immediately replace it with a reliable - quality and suitable - model oil seal, and strictly follow the installation steps.

Excessive lubricating oil

Cause: Excessive lubricating oil can increase the internal pressure of the system, exceeding the tolerance limits of oil seals and seals, resulting in leakage. In severe cases, it will lead to increased component wear and unstable equipment operation.

Maintenance method: Regularly check the lubricating oil level and promptly drain the excess lubricating oil when the oil level is found to be too high.

Wear of components of Raymond mill equipment

Cause: When the Raymond mill is used for a long time, its components will naturally wear, affecting the sealing performance. A decline in sealing performance will lead to oil leakage.

Maintenance method: Regularly evaluate the equipment components. Replace or repair immediately if serious wear or damage is found.

Oil passage blockage

Cause: Impurities in the lubricating oil can accumulate in the oil passage, resulting in oil passage blockage, excessive internal temperature of the system, and triggering oil leakage.

Maintenance method: Clean the oil passage regularly. Special cleaning agents or high - pressure air flow can be used for cleaning. Determine the cleaning frequency according to the usage conditions and working environment.

Equipment operation at high temperature

Cause: High temperature can cause changes in the molecular structure of the sealing material, making it lose its elasticity and toughness. It can also accelerate the oxidation and deterioration of the lubricating oil, leading to the aging and failure of the sealing parts and oil leakage.

Maintenance method: Regularly check the efficiency of the cooling system. If any abnormality is detected, stop the machine immediately for repair.

Improper installation of Raymond mill

Cause: Improper installation will lay hidden dangers for subsequent use, resulting in equipment oil leakage and premature wear of components.

Maintenance method: The installation process should be reviewed. If improper installation is found, it should be rectified immediately to ensure that all installation steps meet the standard specifications.

Design defects of Raymond mill

Cause: Design defects can plant the hidden danger of oil leakage in the equipment from the very beginning, resulting in frequent oil leakage of the main engine.

Maintenance method: Contact the manufacturer or supplier, provide detailed information, jointly explore improvement plans, and ensure the compatibility of components and correct installation during the implementation of improvements.

Improper maintenance of Raymond mill

Cause: Lack of regular maintenance or improper upkeep will accelerate the wear and tear or damage of equipment components, leading to oil leakage.

Maintenance method: A comprehensive regular maintenance plan should be formulated and implemented. Replace vulnerable parts in a timely manner and strengthen the training of equipment operators.

Summary

The risk of oil leakage in the main unit of the Raymond mill can be reduced through in - depth understanding and targeted solutions. It is necessary to start from multiple aspects, such as regularly inspecting and maintaining key components, controlling the amount of lubricating oil, implementing a regular maintenance plan, standardizing installation, resolving design flaws, and strengthening personnel training. Paying attention to equipment maintenance can ensure the stable operation of the equipment and extend its service life.
