Cleaning methods

• External cleaning
  • First of all, before cleaning, cut off the power supply. Start cleaning only after the reducer has stopped operating and completely cooled down. This is to ensure operational safety and prevent electric shock and burns.
  • Use a clean rag or a soft brush to gently wipe the casing of the reducer, removing dirt such as dust and oil stains from the surface. For stubborn stains, a small amount of mild detergent (such as a mixture of dish soap and water) can be used, but make sure the detergent does not enter the interior of the reducer.
  • Pay attention to cleaning the heat sinks of the reducer (if any). Ensure that the gaps between the heat sinks are not blocked by dust or debris, as good heat dissipation is crucial for the normal operation of the reducer.
• Internal cleaning (should be carried out with caution)
  • Under normal circumstances, it is not recommended that users disassemble the reducer for internal cleaning on their own, unless they are professional maintenance personnel. If it is necessary to open the reducer for cleaning, the positions and connection methods of various components should be marked according to the equipment's instruction manual before disassembly.
  • Internal cleaning mainly aims to remove the old lubricating oil, metal shavings and other impurities accumulated on components such as gears and bearings. Special cleaning solvents (such as kerosene or special reducer cleaning agents) can be used. Immerse the components in the solvent and then gently brush them with a soft brush. After cleaning, ensure that the components are completely dry to prevent the remaining solvent from reacting with the newly added lubricating oil.

Maintenance methods

• Inspection and replacement of lubricating oil
  • Regularly checking the oil level of the lubricating oil is a crucial maintenance step. Check the oil level through the oil - level observation window or dipstick on the reducer to ensure that the oil level is within the normal range. If the oil level is too low, it may result in insufficient lubrication of gears and bearings, accelerating wear.
  • Different models of stirring reducers have different requirements for the type of lubricating oil and the replacement cycle. Generally, it is determined according to the equipment's instruction manual. Usually, new oil needs to be replaced after the first operation for a certain period of time (such as 100 - 500 hours), and then it should be replaced every certain period of operation (such as 1000 - 5000 hours). When replacing the lubricating oil, the old oil should be completely drained, and a clean container should be used to hold the new oil to prevent impurities from mixing in.
• Inspection of Gears and Bearings
  • Regularly inspect the wear of the gears. Slight wear is normal, but if there is severe wear, spalling, or cracks on the gear tooth surface, the gears need to be replaced in a timely manner. The inspection methods can include visual observation or using simple measuring tools such as calipers to measure the tooth thickness of the gears.
  • For bearings, check whether there is looseness, abnormal noise, or overheating. A normal bearing should operate smoothly and quietly. If any problem is detected with the bearing, it should be replaced promptly to prevent the fault from escalating.
  • Check whether the seals are in good condition. The function of the seals is to prevent the leakage of lubricating oil and the entry of external impurities into the interior of the reducer. If the seals are damaged, they should be replaced in a timely manner to ensure the cleanliness inside the reducer and the proper preservation of the lubricating oil.
• Regular no - load operation inspection
  • Regularly run the stirring reducer under no - load conditions for a certain period of time (for example, once a month, running for 10 - 30 minutes), which can help detect some potential problems, such as abnormal noises and vibrations. During no - load operation, carefully observe the operating status of the reducer, including the operation of the motor and the meshing sound of the gears. If any abnormalities are detected, stop the machine immediately for inspection. Put it back into use only after troubleshooting.
