Product Structure:
It consists of shutters, upper-guidance system, earth orbitmodule, sealing system, traction, drive device, manual operator,electrical control system, supply power, break and limit controlsystem and safety device etc.
The shutters use high-strength nonmetal as mainmaterial.
Features:
1. Transmittance is above 50%.
2. Self-extinguishing and slow-burning. It is in compliance withNFPA701 (USA), BS5438 (Great Britain), DIN4102 (Germany), M1 ClassB2 (France).
3. Thermal conductivity is less than 1.85W/m2.
4. Temperature limit: -40°C~ 120°C.
5. Weight per square meter is about 6.5 kg/ m2.
6. Sound Insulation Index is 20dB.
7. Durable years: ≥15.
8. Lighting material is used to make indoors unapparent.
PLC (Programmable Logic Controller) can be used ascontrol system; meanwhile visual interface (man-machineinteraction) is equipped to learn the performance of door timely.Drive device employs variable frequency to regulate speed to ensuresmooth moving.
Besides this, control system is also installed with manysafety arrangements, such as audio and video early warning device,pneumatic safety edge, and linkage safety control. Acousto-optic warning is set up before operating, and then any hitor touch from obstacle will stop the moving. It is equipped withlinkage device between wicket and the stable door. If the wicket isopen, the door will not carry out any instruction. Meanwhile it isinstalled with fire coupling which can be used to achieve firefighting joint control.
Principles of Operation:
The sliding door relies on bearing track installed on theground to bear weight. Meanwhile it uses pilot track installed onthe upper part to achieve guidance. Safety slide wire for poweringis set up on the upper side of doorway, while drive motor is fixedon the lower part. Through cables, which are laid in door leaves,power is supplied to motor, and then motor drives chain gear toextend strength to driving wheel. Then the door is open. Controlbox installed on the wall is jog operated, this means the door canmove or stop at any time during operating.
Advantages over traditional doors:
1. Our doors use GRP (nonmetal, high tensile and flameretardant) as lighting material. So it is light in weight, almostgoes 13.5kg per square meter (shutter is 6.5kg and fittings are7kg). Compared with the structure of glass curtain wall, to use GRPmaterial can be 40kg/m2 lighter.
2. Steel members are joined together by bolt on the spot. Whilesectional aluminium material can be used to link lighting panels,but without any exposed screw.
3. All of the designs, including steel member, decorationdesign, drive and rail system, utilize German technology.
4. Drive system (main engine etc.) is imported from Germany. Andoverall electric elements (including control module, slide wire,convertor and PLC) also can choose to import from Germany,
