During the production process, we may encounter a situation where the ring die pellet machine fails to start. If it is confirmed that this is not a power issue, the most likely cause is that the reducer of the ring die pellet machine has seized up. However, the reason for this phenomenon lies in the problem with the lubrication system, either due to the lack or absence of lubricating oil. Another reason is that the equipment has been operating under overload for a long time, causing the reducer to overheat and seize up.
So, how can we confirm whether the reducer of the ring die pellet machine has seized up? Under normal circumstances, we need to first remove the coupling between the motor and the reducer to observe whether the motor can operate normally and eliminate motor faults. Then, move the input shaft of the reducer. If it is found that it cannot rotate, it can basically be determined that the reducer has locked up, and the reducer needs to be repaired or replaced.
During the production process of the ring die pellet machine, continuous observation and daily maintenance of the equipment should be carried out to prevent the occurrence of the reducer seizing. So, what should be noted during production?
1. Regularly observe the oil pressure, oil temperature and flow rate of the ring die pellet machine reducer. If any abnormality is found, the machine needs to be shut down, and the filter and oil nozzle should be cleaned. After cleaning, check that the lubrication is normal before it can be used.
2. The bearings of the ring die pellet machine reducer should be lubricated in the form of splash lubrication. When disassembling, cleaning and reassembling, an appropriate amount of grease should be added, approximately one-third of the bearing space volume.
3. When it is found that the ventilation hole of the reducer of the ring die pellet machine is blocked, the power supply of the equipment should be turned off, and the gas should be removed to clean the filter screen before restarting the machine.
4. When the damaged area of the tooth surface along both the tooth length and height exceeds 20%, the gears should be replaced in pairs. After replacement, a running-in test and load test should be conducted. The gears can be officially put into use when the tooth length reaches 60% and the tooth height reaches 40%.
5. When the ring die pellet machine is in operation, if the oil temperature of the reducer rises above 80℃ or 100℃ and abnormal noise and other phenomena occur, the power supply of the main machine should be turned off, an inspection should be carried out, and the lubricating oil should be replaced to eliminate the fault before continuing the operation.
6. If the output shaft of the ring die pellet machine reducer stops rotating during the rolling process, it might be that the key connection of the reducer is damaged. In such cases, the reducer needs to be disassembled for inspection.
