Root cause analysis:
1. During maintenance and assembly, the engraved lines on the drum were not aligned; Damaged the accuracy of dynamic balance;
2. Lubricating oil deterioration;
3. Main bearing failure;
4. Loose fit between the inner ring of the main bearing and the shaft;
5. Spiral conveyor bearing failure;
6. The bolts of the liquid outlet and slag outlet are not tightened or the pipeline is rigidly connected;
7. Loose head flange causes differential vibration;
8. Differential damage (usually caused by lack of oil);
9. After parking, the valve was not tightly closed and feeding occurred, causing material accumulation in the drum and resulting in a heavy weight;
10. The connection of the rotating components is loose and deformed;
11. The new component being replaced has poor dynamic balance;
12. Serious wear and tear on the relevant components;
13. The material accumulated in the casing rubs against the outer drum.
resolvent:
1. Align the engraved lines again.
2. Replace according to the instructions in the user manual.
3. Replace the bearings.
4. Repair or replace the end cap.
2. Replace the bearings.
6. Tighten the bolts and change the pipeline to an elastic soft connection.
7. Replace the head flange or small end cap.
8. Replace the differential parts.
9. When washing with water and serious material accumulation occurs, stop the machine and turn the differential pulley counterclockwise by hand to discharge the material. After the accumulated material is discharged, it can be put back into use.
10. Check and repair.
11. Adjust or replace.
12. Repair.
13. Clean or regularly rinse.
