Time:2019-05-10 Click:453
Fault one: The motor cannot start or stops slowly after starting
the reason:
1. Overload
2. The electrical circuit is damaged
3. Voltage drop
Approach:
1. Lighten the load and remove part of the coal from the tank
2. Check the circuit and replace damaged parts
3. Check the voltage
Fault 2: The motor and bearing at the end are hot
the reason:
1. Overload operation time is too long
2. Poor ventilation and heat dissipation
3. Bearing lacks oil or is damaged
Approach:
1. Lighten the load and shorten the overload operation time
2. Remove floating coal and debris around the motor
3. Fill the oil and check whether the bearing is damaged
Malfunction 3: The sound of the motor is abnormal
the reason:
1. Single operation
2. Virtual connection of terminal
Approach:
1. Check the cause of single operation
2. Check the wiring
Fault 4: The chain is stuck on the sprocket
the reason:
Tongue derailleur bolts are loose or missing
Approach:
1. Tighten the bolt
2. Replace with a new tongue derailleur
Fault 5: Scraper chain jumps teeth on the sprocket or falls off the bottom chain, cut off the scraper and connecting bolts or chain
the reason:
1. Tangled chain tangles
2. The length of the two chains exceeds the stipulation
Tolerance
3. Excessive wear of sprocket
4. Scraper chain is too loose
5. Excessive bending of the scraper
6. Chain caught in foreign body
Handling precautions:
1. Connect the chain and link
2. Replace the super poor scraper chain segment
3. Replace the sprocket
4. Re-tighten the chain
5. Replace the scraper
6. Remove the stuck foreign objects
Fault 6: Scraper chain vibration is large
the reason:
1. The chute disengages
2. Uneven chute overlap
Approach:
1. Docking the chute
2. Leveling interface
