The first step to adjust the glass door spring: the floor spring has two speed regulating valves. The speed of the 1st and 2nd speed regulating valves can be adjusted independently. The speed can be divided into closing degree (1st speed) and upper Locking speed (second speed); the general closing speed range is 90 to 20 degrees, and the locking speed is 20 to 0 degrees; the basic principle of speed adjustment is: the first speed is slightly faster than the second speed, and when entering the second speed Slow down the speed of the rear door to avoid hitting the heels of pedestrians.
The second step of adjusting the glass door spring: If the connection between the axis of the sky shaft and the main shaft of the floor spring is not strictly vertical to the ground, the movement of the door leaf will bring torsion force to the floor spring, increasing the wear between the main shaft and the bearing, which will eventually lead to Axle leaking oil. The elastic force of the spring will inevitably weaken after a long-term stretching exercise. In this case, it can only be repaired by replacing the new floor spring.
The third step to adjust the glass door spring: If it is not the case of the shaft oil leakage and the weakening of the elastic force, it can be solved by adjusting the 1st and 2nd speed regulating valves, which is just the opposite of the principle of loosening the floor spring.
