The circular vibrating screen is indispensable screening equipment in the production line, up to four layers, and can screen out different sizes of particle size according to customer needs. If the circular vibrating screen is used for too long, some failures will inevitably occur. Today, I will introduce the common failures of the circular vibrating screen and the corresponding solutions in detail.
1. The transmission part of the circular vibrating sieve fails
Reason: improper operation of the operator, insufficient lubricating oil, etc. will cause the transmission part of the circular vibrating screen to fail. Vibrating screen transmission failures include wear of couplings, broken connecting bolts and cracked protective cylinders, damage to the bearing of the belt pulley, and belt tears.
Solution: Regularly check the transmission part, pay attention to the longitudinal and lateral clearance of the bearing during the inspection process to ensure that it is within a safe distance; check the bearing support and add lubricating oil in time; observe the operation of the circular vibrating screen, if there is an abnormal situation Stop and check-in time.
2. The bearing temperature of the industrial circular vibrating screen is too high
Reason: The circular vibrating screen will generate a certain amount of heat when it is working for a long time, which will promote the volatilization of the lubricating oil. The volatilization of the lubricating oil will increase the friction and cause the temperature of the bearing to rise; the lubricating oil is insufficient.
Solution: Reasonably arrange the running time of the circular vibrating screen machine to avoid long-term under load and close the equipment when not in use; check the bearings regularly and add sufficient lubrication to improve the working efficiency of the equipment.
3. The bearing of the circular vibrating screen separators is broken
Reason: The shaft is a metal composite material, it will suffer a lot of torque after long-term use. The raw materials inside the shaft will slowly create a gap. In the long run, the bearing will break; the material of the bearing is weak, the compressive strength is not high, and the fracture will appear. ; Excessive support force of the V-belt will cause an additional bending moment of the shaft and increase the resultant moment. The stress during the stripping work process will increase significantly, even exceeding the allowable stress of the shaft, which will directly cause the shaft to be damaged.
Solution: Choose an experienced and regular manufacturer to ensure that the selection of components is reasonable; regularly check the bearing wear and replace it in time; under the premise of ensuring normal transmission, try to reduce the tension of the V-belt.
4. The screen surface ages faster
Reason: Most of the screen plates of the circular vibrating screen machine use polyurethane screen surface, but the anti-aging performance of polyurethane is not high, which leads to the rapid aging of the screen surface; the operator does not tighten the screen surface when installing the screen surface, thereby accelerating The aging of the screen surface.
Solution: Choose a high-quality screen surface; check the looseness and damage of the screen surface regularly, tighten and replace the screen surface in time; when replacing the screen surface, make the tension plates on both sides have the same and uniform tension.
The above are the four common failures of circular vibrating screens and the corresponding solutions. We should also pay attention to the daily maintenance and maintenance of the circular vibrating screen during use so that our equipment can work efficiently.
