The floor spring door, which is a kind of door that has a hydraulic door closer ground spring hardware, is now a lot of glass doors. The adjustment of the floor spring door is usually the floor spring door is too loose or too tight, resulting in the door closing is not smooth, the use of the problem, which is the need to adjust the floor spring tightness. So, how to adjust the floor spring door? Generally speaking, the adjustment of the floor spring door should be divided into the adjustment when it is too loose and the adjustment when it is too tight. For the specific adjustment method, please see my summary below.
Introduction of floor spring door
It can make the glass door return to the initial closing state automatically, so that the door will not be thrown off when it is closed. The technical key of the floor spring is the load-bearing seat in the lower part of the spindle, which determines the load-bearing level of the floor spring, which needs to carry the weight of the door body. The adjustment of the floor spring door is mainly to adjust its regulating valve or to solve the problems of oil leakage from the spindle and weakened elasticity.
The adjustment method of the floor spring door whose cushioning effect is too loose
The ground spring of the floor spring door has two adjustment valves to adjust the speed, the first speed and the second speed of the adjustment valve each independent speed can be adjusted, and its speed can be divided into closing degree (first speed) and locking speed (second speed). The general range of closing speed is 90 to 20 degrees, and 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 door must slow down after entering the second speed so as not to touch the heel of the pedestrian.
Floor spring door floor spring buffer effect is too tight adjustment method
Most of the floor spring buffer effect of floor spring is too tight because of oil leakage from the shaft and weakened elasticity. If the axis line between the sky shaft and the ground spring spindle is not strictly perpendicular to the ground, the movement of the door will bring great torque to the ground spring, increase the wear between the spindle and the bearing, and eventually lead to oil leakage from the spindle. Inevitably, the spring will weaken after a long stretching movement, and in this case, the spring can only be repaired by replacing it with a new one. If it is not a case of oil leakage and weakening of the shaft, it can be solved by adjusting the first and second speed adjustment valves, which is the opposite of the principle of loosening the ground spring.
