| The maintenance of the coal mill end cover 20MG32.11.09J.48 is an important part to ensure the long-term stable operation of the equipment. The following are some key maintenance measures: 1. Regular inspection: After each shutdown, check whether the bolts of the coal mill end cover and related parts are loose. If they are loose, they must be tightened. 2. Lubrication management: Check the amount of lubricating oil in the front and rear bearing chambers of the main engine and refill them on time, especially the bearing chamber should inject lithium-based lubricating oil into the axial end cover oil nozzle. 3. Crack monitoring: For end covers with cracks, emergency measures should be taken to control the expansion of cracks, and a specific plan should be formulated to replace the outlet end cover to ensure safe and stable operation of the equipment. 4. Cleaning and maintenance: Clean the end cover joint surface regularly to ensure that there is no dust, dirt or other impurities to prevent contamination of the lubricating oil or damage to the equipment. 5. Replacement and repair: For worn or damaged end covers, they should be replaced or repaired in time to avoid load limit losses caused by equipment shutdown. 6. Bolt tightening: When installing the end cover, push the end cover evenly to prevent the end cover from deflecting and the rubber ring from being squeezed out due to excessive pushing speed, and tighten each bolt on the end cover with a torque wrench to the specified torque. |
