But in the process of operation, there will appear different problems, how to solve these problems? Luoyang Dahua will give you a general introduce.
I. The machine body swings too big
Reason:
1. Impeller wearing part is serious worn;
2. Feeding granularity is too big;
3. Impeller passage is blocked.
Solution:
1. Replace wearing part;
2. Reduce feeding granularity;
3. Remove stoppers in the impeller passage
II. The products granularities are too big
Reason: V-belt is too loose
Solution: Tighten the V-belt
III. The resistance is too big during no load running
Reason: There are materials inside the sealing cover on the bearing
Solution: Open the sealing cover to clean the materials
IV. Bearing is hot
Reason:
1. Lack of oil or the powder inside the bearing;
2. Bearing is damaged.
Solution:
1. Add oil or clean the bearing;
2. Replace bearing.
V. Metal parts collide with each other
Reason: Liner plate or the wearing parts of impeller are peeling.
Solution: Retighten the metal parts.
