Abstract: the spring is a hydraulic closed-door device, except that its pressurized spring is a snail rather than a gear bar. As snails can rotate in reverse, the springs can be used for open doors in both directions, while closed doors can only be used for open doors in one direction. The technical key to the spring is the bearing of the lower axis, which determines the weight of the spring. The method of installing the spring door is simple, starting with drawing lines, reconnecting the centre of the spring with the axis of the gate, and then openings the ground on the basis of instructions and physical objects
The formation of the spring door
1. Automatic door tracks
It is made of high-intensity, grinding aluminium. Simplicity can be cut, and can be adapted and installed at the optimal size, even at various opening widths such as shops. Unit length based on 2. 5 m。
2. Automatic door controllers
The detection signal, the driver, and the control of the door moving in the right way。
3. Automatic door generators
Use of a small, high-power straight-flow carbon-free scrubber, combined with a high-speed gearbox system with high speed speed speed and low noise, and then drive synchronized bands。
4. Automatic door sensors
Open the signal to the automatic door when a person enters or leaves it。
5. Automatic door belt tight-wheel components
Constant tension belts are attached to a tight wheel to regulate the belt's tension, and the belt's constant adjustment mechanism keeps constant tension in the synchronous gear band。
6. Auto-door cranes
All of them are in a regulated structure, where the parts of the hanger are pressured by cold-rolled steel plates, and on the hanger is a steering wheel made of specially designed materials, which moves along the arc of the orbit。
Automatic door connection end。
7. Automatic door belts
Select to drive the door fan movement by connecting to the hanger with a synchronous gear belt that moves efficiently。
Installation of the spring door
1. Draw a line to reconnect the centre of the spring axis with the door axis。
2. According to the instructions and physical openings on the ground, the size of the holes shall be fixed to the spring shell and shall not be relaxed。
3. Put the spring in the open hole。
Lift up the door-knoted doors so that the re-axis of the springs are inserted into the re-axis of the doors。
5. Regulate the screws in the three directions of the spring, maintaining the verticalness of the doors, and the resonance of the top and down axes。
6. Regulate the speed of closure。
7. Cover the floor with springs。
Note: the accuracy of the installation of the spring has a significant impact on its useful life. Quality defects in the springs are mainly: in-house oil spills and geoaxis. The oil spill in the body is due to the ground spring casting process, which results in an increase in the internal liquid pressure of the sand eye after installation. The eccentricity of the axis can lead to de-routing of the door after installation from the centre of the door section, and although some quality deficiencies can be remedied through in-house repositioning, it would be preferable to replace it in contact with the manufacturer. The end of the spring's useful life is the loss of axle oil and the reduction of impact. If the axle is not connected to the main axis of the spring vertically, the movement of the doorknob will cause a great twist to the spring, increasing the wear between the main axle and the bearing, and eventually causing a leak of oil in the axis. Inevitably, springs are reduced after long stretching。
Common malfunctions and maintenance of spring doors
1. The doors are not closed
Solutions: see if the locks are loose, and the proper cushions can be solved, and if the locks are broken, reset the shop with one, generally due to glass doors。
Two, close the door
The solution: if you close the door, you hear a sour tooth friction, which is likely to be damaged by the internal spring. The method of repairing it is to open the cord to see the internal situation and, if the spring is broken, replace the spring, although this operation is difficult and does not recommend its own solution。
Three, lower door
Solutions: there will be a situation of endurance when everything lasts long, and if there is not a problem with the downslide of the door, it will generally be a situation where the capacity of the spring reaches its limit, or where there is a problem with the internal piecework. If you have been using it for a long time, it is recommended that no repairs be made, because it is not surprising that many low-quality springs have problems in about 10 years, and it is recommended that a new brand and model be bought, after all, the pit on the ground is still in place, and it is convenient to install it。
