1. Loosen the four adjusting bolts and adjust the belt tension.

2. Confirm the resistance when walking and whether there is heavy scene when the door moves.

3. Synchronous belt (triangular belt is used by some manufacturers): it is mainly used to transmit the power produced by the motor and pull the door leaf spreader wheels.

When the revolving door is in use, it repeatedly stops a series of operations such as starting, braking and carrying out. If it is used intermittently for a long time, it may make some mechanical connecting parts loose, lack of oil in the driving reducer, major wear of the bearing wheel, change of the sensing area of the safety sensor, weakening the braking performance, mastering the accumulation of dust and so on. The presentation of these scenes is not unique to the revolving door, but also in other products, such as cars. In fact, only moving facilities will present the above situation. If the revolving door presents the above picture, it may become a large part due to the problem that it can be handled by changing small parts, which may affect the service life of the automatic door in major cases; Some will also cause the misoperation of safety fragmentary sensors, resulting in the reduction of the safety of the revolving door, and personal injury will occur in major cases.

1) Polymer materials

3. Good sealing performance of the revolving door: the characteristic of the revolving door is that it is sealed to the outside environment, while the internal temperature and heat loss are reduced, which may not save electricity to some extent, and adhere to the high-quality indoor environment.
