Some damage factors and corresponding solutions for plastic shredder

The use of plastic shredder equipment is becoming more and more extensive, so many people want to buy it. During the use process, some users report that the bearing of the plastic shredder equipment is damaged faster, so this phenomenon is caused by what is the reason? Today, I will introduce some damage factors and corresponding solutions to you.

1. Too much, too little or aging lubricating oil in the bearing is the main reason for overheating and damage to the bearing. Therefore, it is necessary to add lubricating oil on time and quantitatively according to the requirements of the instruction manual. Generally, the lubricating oil occupies 70-70-100% of the bearing space. 80%, too much or too little is not conducive to bearing lubrication and heat transfer.

2. The bearing of the plastic shredder is gravitationally hit with a hammer or heavy object, causing deformation. The use time is gradually accumulated, and the original shape of the bearing will be continuously changed. The deformed bearing will not only be processed and produced. It will wear itself, and the bearing seat on which the bearing is installed will also be worn, and other components will also be worn, reducing production efficiency.

Three, the two bearing seats are uneven, or the rotor of the motor and the rotor of the plastic shredder are not concentric, which will cause the bearing to be impacted by extra load, which will cause the bearing to overheat. In this case, stop the machine immediately to eliminate the fault to avoid early damage to the bearing.

Fourth, foreign objects such as sand and metal chips enter the bearing of the plastic shredder. Mainly include: opening the bearing package prematurely; unclean environment during equipment operation; unclean working environment of the bearing; working medium pollution, etc. Suggestion: Do not unpack the bearing before the official start-up; keep the equipment in a good operating environment; clean the equipment in advance before use; strengthen the sealing measures of the bearing.

Five, fatigue damage is a common damage form of plastic shredder bearings. Reasons: overloaded operation for a long time; not timely protection; improper repair; aging equipment, etc. Suggestion: choose the appropriate bearing type, and replace the tired bearing in time.
