Nanjing glass door making repairs

In spring is a hydraulic door closers, but its compression spring means is a worm gear instead of a rack and pinion. Because the worm can forward and reverse rotation, so in the spring can be used for two-way opening the door, and behind closed doors can only be opened for a one-way door. Technology is the key to spring bearing seat lower part of the spindle, which determines the floor spring load rating. Because for two-way door to spring to carry the weight of the door, more behind closed doors, the weight of the door-to-ground spring selection play a decisive role. In practice, the doors are generally not exceed the weight, so the door width and wind pressure on the ground spring model choice is the first factor. Also note that the aspect ratio, ie the ratio of height and width, if it is too disproportionate doors is not properly used. From the perspective of the production point of view, in the spring of worm gear structure makes compression spring than rack and pinion door closers small, closed in the spring of the arm is short, so the quality to spring for the structural design and precision dependence higher. Further, since the two-way doors open flat on the ground along the leaf spring has a great force, so the gap between low-end and high-end in the spring of life will be great in the spring. 1.
