Circular vibrating screen transmission failure solution
published date: 11-17-2020
The vibrating screen is mainly composed of vibrator, screen box, support or suspension device, transmission device and other components. Once a transmission failure occurs, the circular vibrating screen will be unusable, which will seriously affect normal production. At the same time, the transmission failure of the vibrating screen is more complicated and difficult to repair.
Reasons and countermeasures
Common drive failures of the circular vibrating screen include wear of the coupling, broken connecting bolts, cracked protective cylinder, damage to the bearing of the belt pulley and belt tear.
For this reason, the operators of the circular vibrating screen need to conduct preventive inspections on the transmission part on a regular basis. During the inspection process, it is particularly necessary to pay attention to the longitudinal and lateral clearances of the bearings to ensure that the spacing meets the requirements. Lubricants need to be added in time to avoid serious wear; Weekly inspect the bearing support and add lubricating oil in time; observe the operation of the circular vibrating screen. If there is an abnormal situation, the operation must be stopped and the system checked to avoid more accidents.
Too high bearing temperature is also a common fault in the use of circular vibrating screens. Although bearing temperature is too high, it will not immediately affect production. However, if the temperature continues to be too high for a long time, it will inevitably affect the service life of the bearing. Big impact. Therefore, technicians must also attach great importance to this issue.
Long-term work will inevitably generate a certain amount of heat, which will promote the volatilization of the lubricating oil, and the volatilization of the lubricating oil will further increase the friction and increase the temperature. Therefore, it is necessary to reasonably arrange the operating time of the circular vibrating screen to improve the operating efficiency of the equipment, avoid long-term continuous work, and it can be closed in time when the circular vibrating screen is not needed.
Lack of lubricating oil will inevitably cause the temperature to rise continuously. It is necessary to check the bearings regularly and add lubricating oil to avoid excessive temperature caused by insufficient lubricating oil.
