How to deal with the overheating of the paper shredder
The overheating of the paper shredder will accelerate the wear of the hammer blade and the pin shaft, resulting in a decline in work efficiency, so it needs to be dealt with in time. When the machine overheats, it should first stop immediately, then find out the cause and eliminate the fault, and finally do maintenance work. After 3000 hours of use, the new oil should be replaced, and then the second oil change after 500 hours of use, and then later Change it every 1000 hours.
Why is the pulverizer overheating
1 or 2 bearing seats are uneven, or the rotor of the motor and the rotor of the pulverizer Misalignment 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, so as to avoid the early damage of the crusher bearing.
2. Too much, too little or aging lubricating oil in the bearing is also the main reason for bearing overheating and damage. Therefore, the crusher should be filled with lubricating oil on time and quantitatively according to the requirements of the instruction manual. General lubrication accounts for 70%-80% of the bearing space, too much or too little is not conducive to bearing lubrication and heat transfer. Bearings extend their service life.
3. The fit between the bearing cover and the shaft of the crusher is too tight. If the fit between the bearing and the shaft is too tight or too loose, the bearing will be overheated. Once this problem occurs, friction noise and obvious swinging will occur during the operation of the equipment. Shut down the machine to remove the bearing, repair the friction parts, and then reassemble as required.
4. The crusher bearing is damaged, the main shaft is deformed or the rotor in the crushing chamber is unbalanced, which will cause the crusher to overheat. It is necessary to replace the new bearing, straighten the main shaft and balance the rotor.
5. The opening of the adjustment plate of the crushing chamber is too small, and the air intake is not large, resulting in a small negative pressure in the crushing chamber, poor powder discharge, and excessive powder crushing, resulting in the heat in the crushing chamber not being able to be timely. Exhaust, at this time, the opening of the adjustment plate must be checked to eliminate the fault.
6. When the pulverizer is working, the hammer blade rotates at high speed to hit and rub the material. The moisture and fine dust in the material will be adhered to the bag of the pulse dust collector, and the wind resistance will increase. The air volume and air pressure of the dust collector will be lost. In severe cases, the pulverizer will be overheated and the output will be reduced. Therefore, the bag of the dust collector must be replaced or cleaned in time.
7. When the pulverizer is working, let sufficient cold air enter from the air inlet of the feeder, and pass the powder out through the sieve through the pulverizing chamber, which is the only correct channel for the air path. If the installation accuracy is not high, the door, cover, air duct and joints are not well sealed, which will also cause short circuit in the air path, and the air volume passing through the crushing chamber will be insufficient, causing the crusher to overheat.
8. Improper use of the pulverizer and long-term overloaded work will also cause the pulverizer to overheat and even burn the motor. The correct condition is that the motor is working at 90% of the rated load.
