Want to reduce the shutter door failure rate should start from the study of its frequent problems, shutter doors often appear problems are:
1.There are obstacles in the running track of the door body in the descending process. The falling of the door body after it falls on the obstacle does not stop, resulting in the door body being rolled back or the door plate being out of position.
2. The ectopia between the door plate and results in uneven ends of the door body, and the track is easy to be stuck, resulting in ectopia deformation of the door body or derailment and reverse rolling.
3. The friction between the door and the track is large, the door wear through.
Therefore, the solution can also be started from three aspects:
First of all: rolling doors should be selected with resistance rebound motor or resistance rebound module, when the door body falls in the process of encountering obstacles automatically stop and convert to the rising state.
The 2nd: choose high strength metal or high grade nylon to seal undertake door plank two end limit, avoid door plank amlposition.
Finally: positioning wheel is installed in the track to limit the track of the door body and avoid friction with the track, and sealing strip can be installed in the track to reduce friction and sound insulation.
