Fast rolling shutter door is a widely used category in modern industrial production, which has the advantages of speed, efficiency and safety. However, during use, the fast rolling door may have various faults and need to be repaired in time. This article will introduce the common faults and maintenance methods of fast rolling doors.
1. Common faults of fast rolling doors.
1.Roller shutters cannot be raised or lowered.
When a fast roller shutter fails to raise or lower, it may be due to the following reasons:
1) Power failure: Check whether the power supply is normal and whether the power cord is loose or damaged.
2) Motor failure: The motor may be damaged or overheated, and it is necessary to check whether the motor is working properly.
3) Limiter failure: The limiter may be damaged or the position is incorrect, you need to check whether the limiter is working normally.
2.The lifting speed of the roller shutter door is abnormal.
When the lifting speed of a fast rolling shutter is abnormal, it may be due to the following reasons:
1) Excessive load: The roller shutter may be carrying an excessive load, resulting in a slower speed.
2) Motor failure: The motor may be damaged or overheated, and it is necessary to check whether the motor is working properly.
3) Transmission system failure: The transmission system may be damaged or loose, and it is necessary to check whether the transmission system is working normally.
3.Roller shutters are too noisy.
When a fast rolling door produces excessive noise during operation, it may be due to the following reasons:
1) Transmission system failure: The transmission system may be loose or damaged, and it is necessary to check whether the transmission system is working normally.
2) Bearing damage: The bearing may be damaged or worn, and the bearing needs to be replaced.
Second, the maintenance method of fast rolling shutter door.
1.The maintenance method of the roller shutter door cannot be raised.
1) Check whether the power supply and power cord are normal, and replace or repair them if necessary.
2) Check whether the motor is working normally, if there is a problem, the motor needs to be replaced or repaired.
3) Check whether the limiter is working normally, if there is a problem, you need to adjust the limiter or replace the limiter.
2.Maintenance method for abnormal lifting speed of roller shutter door.
1) Check whether the load is too large, and reduce the load if necessary.
2) Check whether the motor is working normally, if there is a problem, the motor needs to be replaced or repaired.
3) Check whether the transmission system is working normally, if there is a problem, the transmission system needs to be adjusted or the transmission system components need to be replaced.
3.Maintenance method for roller shutter door that is too noisy.
1) Check whether the transmission system is working normally, if there is a problem, adjust the transmission system or replace the transmission system components.
2) Check whether the bearing is damaged or worn, and replace the bearing if there is a problem.
3. Maintenance precautions.
1.Before carrying out repairs, the power should be turned off to prevent electric shock.
2.During the maintenance process, you should pay attention to safety and do not disassemble or repair electrical parts at will.
3.For some complex faults, it is recommended to ask professional maintenance personnel for repair.
