Maintenance methods and common faults of clean eight-room rolling shutter doors
Maintenance methods and common faults of clean eight-room rolling shutter doorsRolling shutter door repair methods:1. Rolling shutter door maintenance method: When the electric rolling shutter door cannot be started or starts slowly, first check whether the motor can operate normally. If not, replace the motor. Then check whether there is any stuck place in the mechanical part, if so, just clear it. 2. When the controller fails, the power contactor should be replaced first, and then the transmission gear should be replaced. When the vibration frequency of the motor is too high and the noise is too loud. *First check whether the bearings are aging, then check whether the sliding wheel needs to be lubricated, etc., and check whether the motor is damaged. 3. We would like to remind everyone that the sliding wheels and drivers should be lubricated at least once a year, the transmission belt should be inspected once a year, and the wear of each component should be checked regularly. Common faults: 1. Slow or no rotation, the main reason may be that the motor is damaged, the circuit is short-circuited, the load is too large, or the stop button does not rebound. The solution to this fault is to replace the damaged motor, check whether the routing is connected, move the slider of the limit switch to touch the switch contact, adjust the switch position, and check whether there is any mechanical resistance. 2. Control failure. When the contacts of the contactor are stuck, the micro switch fails, the sliding screw is loose, the slider or nut cannot move with the screw, the stopper driving gear is disconnected, and the button up and down keys are stuck. For this kind of door failure, the solution is to replace the contactor, replace the micro switch or contact piece, tighten the screw, replace the button, or replace the transmission gear of the plug. 3. The reason why the rolling shutter door fails when the chain does not move may be that the chain link is stuck, the endless chain blocks the cross groove, and the pawl does not have a ratchet. Therefore, the rolling shutter door malfunctions. The lubrication will need to be changed and the round chain straightened. Just adjust the relative position of the pawl and the pressure bracket. |
