The sound of the normal operation of the fast door during operation is relatively small and relatively stable, rather than the harsh noise. When the fast door opens or closes, it will make a lot of noise. It must be where there is a fault, and the reason for the noise of the fast door in operation is nothing more than the following situations:
Reason one: the bearing is distorted, damaged and dirty. When the ball bearing of the fast rolling door is dirty, damaged or deformed, the motor will give a certain sound reminder.
When processing, you need to re-correct the fast door motor, check the ball bearings, clean the dirty ball bearings, if necessary, add or replace the grease, the noise can be reduced.
Reason two: the rotating parts of the motor vibration.
To solve the problem, we need to find the cause of the vibration of the rotating parts of the fast rolling door. According to the experience of Hubei fast rolling door for many years, the unbalance of the motor is the main reason, and the problem of unbalanced difference is eliminated, and the noise is too large.
Reason three: the cooling channel of the fast door motor has foreign matter. When there is a foreign body in the heat dissipation channel of the fast door motor, the hot air will come into contact with the foreign body, and the noise will be taken for granted, and after the foreign body is cleaned up, the noise will be gone.
