How much do you know about floor spring doors

Floor spring doors, that is, a kind of door with floor spring hardware accessories with hydraulic door closers, are now the case with many glass doors. The adjustment of the floor spring door is usually because the floor spring door is too loose or too tight, which causes the door to not close smoothly and has problems in use. Only then does the tightness of the floor spring need to be adjusted. So, how to adjust the floor spring door? Generally speaking, the adjustment of the floor spring door needs to be divided into adjustment when it is too loose and adjustment when it is too tight. For the specific adjustment method, please refer to the summary below.

Floor spring door introduction

The floor spring door is a two-way opening door that works by compressing the spring device, which can make the glass door automatically return to the original closed state, so that when the door is closed, the door will not hurt people due to the closing of the door. The technical key of the floor spring is the bearing seat at the lower part of the main shaft, which determines the bearing level of the floor spring, and the floor spring needs to carry the weight of the door. The adjustment of the floor spring door is mainly to adjust its regulating valve, or to solve the problems of oil leakage and weakening of the elastic force of the shaft.

The adjustment method of the cushioning effect of the floor spring door is too loose

The floor spring of the floor spring door has two speed regulating valves. The speed of the first speed and the second speed regulating valve can be adjusted independently. The speed can be divided into the closing speed (first speed) and the 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 the speed of entering the second speed rear door must be slowed down to avoid hitting the heels of pedestrians.

The adjustment method of the floor spring cushioning effect of the floor spring door is too tight

The cushioning effect of the floor spring of the floor spring door is too tight, mostly due to the oil leakage of the axis and the weakening of the elasticity. If the connecting line between the axis of the sky shaft and the main shaft of the ground spring is not strictly vertical to the ground, the movement of the door leaf will bring great torsion to the ground spring, increasing the wear between the main shaft and the bearing, and eventually causing the shaft to leak oil. The spring will inevitably weaken the elastic force after long-term stretching movement. In this case, it can only be repaired by 

replacing the new floor spring. If it is not the case of shaft oil leakage and weakened elasticity, it can be solved by adjusting the first and second speed regulating valves, which is just the opposite of the principle of loosening the floor spring.

In the above, we learned about the floor spring door, and how to adjust the floor spring door too loose or too tight. It can be seen that the adjustment of the floor spring door can directly adjust its regulating valve, or because there is a problem with the floor spring of the floor spring door, this fault must be solved first. Now, the floor spring door is very widely used in practical applications, so everyone is likely to encounter the adjustment of the floor spring door. Here, the editor recommends that you study the adjustment method carefully, know the working principle of the floor spring door, and learn to solve this fault.
