To extend the service life of agricultural machinery, the repair and maintenance of agricultural machinery forgings is very important. The following are some guidelines for the maintenance of agricultural machinery forgings: Regular inspection and maintenance: regularly check the status of agricultural machinery forgings, including fasteners, lubrication, wear degree, etc. According to the frequency of agricultural machinery and working environment, develop the corresponding maintenance plan, and timely lubrication, replacement of parts and other maintenance work. Pay attention to lubrication: agricultural machinery forgings often need lubrication maintenance to ensure normal work. According to the different parts and requirements of agricultural machinery forgings, select the appropriate lubricant, correctly apply or inject lubricating oil to ensure that the lubricating film fully covers the exposed surface. Timely replacement of worn parts: With the growth of use time, parts in agricultural machinery forgings will wear. Once it is found that there is wear or aging of the forging, it should be replaced or repaired in time to avoid further damage to the entire system. Pay attention to the use of environment and operation methods: in the use of agricultural machinery forgings, attention should be paid to avoid poor working environment and operation mode. Reduce the excessive load work of agricultural machinery forgings, avoid overload operation, pay attention to not violent collision, etc., to reduce the damage to agricultural machinery forgings. Storage and protection: When agricultural machinery is not used, it should be properly stored, and pay attention to the protection of agricultural machinery forgings. Keep dry, moisture-proof, and cover with dust cover or use special packaging materials to prevent external corrosion or damage to the forgings. Regular maintenance and maintenance training: Provide regular maintenance training for agricultural machinery forgings, so that farmers can understand and master the correct maintenance methods and skills, and can find problems in time and take appropriate measures. The above are some maintenance guidelines for agricultural machinery forgings to extend the service life of agricultural machinery. Through scientific and reasonable maintenance, the failure rate can be reduced, the service life of agricultural machinery can be extended, and the work efficiency and production efficiency can be improved.
