How to clean and maintain drum wood chipper?

As an important equipment in the wood processing industry, the cleaning and maintenance of drum wood chippers are crucial for maintaining efficient operation and extending their service life. The following is a detailed cleaning and maintenance guide for drum wood chippers, for reference by operators.

1. Daily cleaning

1. Shutdown cleaning: After each shutdown, the residual wood chips inside and outside the drum wood chipper should be cleaned immediately. Use compressed air or a brush to remove dust and sawdust from inside the machine, especially from key areas such as drum blades and screens.

2. Check and clean the feeding port: Ensure that the feeding port is unobstructed and not blocked by large pieces of wood or debris. This helps to improve cutting efficiency and reduce equipment wear.

2. Regular maintenance

1. Lubrication and maintenance: Regularly check and replenish the lubricating oil of each moving part. Add butter to the moving parts once a day and lithium based grease to the main bearings every 300 hours. Ensure that the equipment operates in a fully lubricated state, reducing wear and friction.
2. Check fasteners: Before starting the whole machine, check whether all solid bolts are loose to ensure that the equipment is firmly connected.
3. Clean the air pump filter: Clean the air pump filter of the drum wood chipper every half month to ensure unobstructed air passage and avoid affecting equipment performance.

4. Replace hydraulic oil and filter element: After the drum wood chipper has been working continuously for about 500 hours, the hand oil pump should be cleaned and the hydraulic oil and filter element should be replaced. This helps to maintain the cleanliness and stability of the hydraulic system.

3. Deep maintenance

1. Disassemble and wash bearings: After six months of cumulative operation (about 2000 hours) of the drum wood chipper, all bearings should be disassembled and washed, and new lubricating grease should be replaced. The knife roller bearing should use lithium based grease.
2. Cleaning the chains: Check and clean all chains, lubricate and lubricate them to ensure smooth operation.

3. Check hydraulic components: Clean the hydraulic components, check the sealing condition of the oil cylinder, and replace damaged components. This helps to maintain the stability and reliability of the hydraulic system.

4. Precautions

1. Safe operation: When performing cleaning and maintenance work, be sure to cut off the power and ensure that the drum wood chipper is in a stopped state. Operators should wear protective equipment to avoid accidents.
2. Professional maintenance: For faults or damaged parts of the drum wood chipper, professional maintenance personnel should be contacted in a timely manner for handling. Do not disassemble or repair the equipment on your own to avoid causing greater damage.
3. Rust prevention treatment: Pay attention to the rust prevention treatment of equipment, especially in humid or rainy seasons. Regularly inspect the surface of the equipment for signs of rust, and promptly use rust remover or perform sandblasting treatment.
By following the above cleaning and maintenance guidelines, it is possible to effectively maintain the good operating condition of the drum wood chipper, extend the service life of the equipment, and improve production efficiency.
