Each wood pellet machine needs to be equipped with a reducer when operating, which is determined by its mechanical principles. However, during the long-term heavy load use, the wood pellet reducer will inevitably have some failures. How should these failures be handled?
1. If you find that the oil pressure, oil temperature and flow of the reducer of the wood pellet machine is abnormal, you need to clean the filter and oil nozzle. After cleaning, check to be normal lubricated before it can be used.
2. The bearings of the wood pellet machine reducer must be splash lubricated. When disassembling, washing and reinstalling, an appropriate amount of calcium-sodium grease must be added, which is about 1/3 of the bearing space volume.
3. If the vent hole of the wood pellet machine reducer is found to be blocked, the gas exchange filter should be removed and cleaned before installation and use.
4. When the damage area on the tooth surface exceeds 20% along the tooth length and tooth height direction, the gears should be replaced in pairs. After replacement, the gears should be run and load test run. The tooth length contact reaches 60% and the teeth can be used officially. It is very important to replace pairs and bold them in pairs. 4 is very important. Don’t change the pieces and change the same pieces in a few days.
5. When the wood pellet machine is working, if the temperature rise of the reducer oil exceeds 80℃, the oil tank temperature exceeds 100℃, and abnormal noise is generated, it should be stopped. Check the cause and replace the lubricant and eliminate the fault before continuing to operate. Temperature is important, remember these two and touch the gearbox frequently. Early detection and maintenance.
6. When the pellet machine reducer rotates, the output shaft will not rotate. It is possible that the reducer key connection is damaged, so the reducer must be disassembled and inspected.
Protection method of wood pellet machine reducer
1. Lubrication: The lubricant reducer should check the oil standard oil level frequently. It is recommended to use gear oil No. 32, and use oil with high viscosity in summer. After 500 hours of operation, drain the oil and replace it with new oil. The reducer should check the oil standard oil level frequently, and the amount of lubricating oil added should be based on the safe oil level.
2. The oil level of the gear reducer should be checked frequently. If the oil level is lower than the specified position, add lubricating oil frequently and strictly prevent excessive addition, causing oil leakage. The gearbox mechanical oil should be replaced when the machine is operated for 500-1000 hours, and the others should be replaced when the machine is operated for 300 hours.
3. Check the bolts of the lifting reducer frequently and do not run. If there is looseness, it should be firm in time.
4. After each shift of the wood pellet machine, it is necessary to remove dust on the surface of the equipment.
5. The equipment is inspected every six months or a year and replace consumable parts. The maintenance of each equipment depends on the operation conditions.
6. The display lights, air switches and stroke switches of the electrical system should be checked frequently. If damage is found, replace them in time.
