Rolling shutter door can protect the safety of a place to a certain extent and prevent property loss. Rolling shutter doors are also widely used. The electric rolling shutter door is widely used for vehicles entering and leaving some factories and garages of some houses. But any equipment in the long-term operation will inevitably have a fault, rolling shutter door is no exception, then, do you know how to repair the rolling shutter door? It doesn't matter if you don't know. Next, Jinan rolling shutter door will introduce you in detail | I hope it can help you!
Jinan roller shutter door
1、 The common faults of rolling shutter door in maintenance are as follows:
1. Slow or no rotation
The main reason is that the motor is burnt out, short circuit, excessive load or stop button does not rebound and cannot reset.
The solution to this problem is to replace the burned motor, check whether the line is connected, move the slider of the limit switch to contact the switch contact, adjust the switch position, check whether the mechanical parts are blocked, and if so, eliminate the blockage.
2. Control failure
When the contactor contact is stuck, the microswitch fails, the slider screw is loose, the support plate moves, the slider or nut cannot move with the screw rotation, the transmission gear of the limiter is damaged, and the up and down keys of the button are stuck.
For this kind of rolling door fault, the solution is to replace the contactor, micro switch or contact, and the fastening screw is reset by the plate, button or transmission gear of the limiter.
3. The zipper doesn't move
The reason for this kind of failure of rolling shutter door is that the chain pressing frame is stuck, the ring chain is stuck in the cross groove, and the pawl is not separated from the ratchet wheel.
So we already know the intention to cause this kind of rolling door failure. Now let's understand the solution: change the lubricating oil and straighten the ring chain. Adjust the relative position of the pressure frame.
4. Motor vibration or noise is large
Fault causes: the brake disc is not balanced or broken, the brake disc is not tightened, oil shortage or bearing failure, gear meshing is not smooth, oil leakage or serious wear, motor current noise or vibration.
Treatment method: replace the brake disc or readjust the balance, tighten the brake disc nut, and replace the bearing. Repair, lubricate or replace the output gear of the motor shaft, check the motor, and replace if damaged.
2、 Jinan rolling shutter door maintenance method:
The circuit board should be carefully inspected for damage. For example, whether the fixed pin is loose, whether the equipment is connected incorrectly, whether the components are faulty, etc. Maintenance personnel can quickly analyze the fault and detect it according to the phenomenon provided by users.
Most rolling shutter control systems use electromagnetic relay as the controller, and the contact switch of the relay will produce obvious "tick" sound. When there is no sound, it can be determined that the relay is damaged after confirming that there is no fault in the relay drive motor.
In the process of maintenance, we often touch the stability of integrated devices, such as some components, lightning tubes, transformers and driving tubes after electricity, to feel whether the temperature is correct, such as fast heating, high temperature, no short circuit fault circuit circuit, etc., and can identify the bad equipment.
