When closed, high-strength nylon wheel center around the spring galvanized pipe rotation, the already tightening the spring due to the generation of torque (or rotational force) naturally relax, help to close. However, when closing the other side of the corresponding spring are taut. When open, the spring tension of the torque due to the effect of natural door body back to their original position to achieve the purpose of the booster.
Normally, the market of such springs are usually dense body, but between the coils in the twisting process will naturally distorted, generating too much resistance, affecting the normal operation of the rolling gates. Therefore, Fiat door industry under long-term testing, coils pitch adjustment width of 2mm to reduce friction, avoid them generate resistance to rotation or rotational force.
Kuaiyi's industrial doors O-Vol gate selection 65MnB spring-like material, is characterized by high strength, good performance. Specific parameters are as follows:
An outer diameter（mm）
Number of turns
The end of the form
The above specification applies only to door torsion body weight 4.0 ~ 5.0kg / m, using a flywheel having a diameter of 280mm of Australian-style gate. Delightful door industry currently published only for Aussie shutters door thickness of 0.426 ~ 0.526mm spring scaling parameters, if needed per square weighing more than 8kg of doors, please call Kuaiyi door industry Technological Development 0663 - 3232888 Request for Information . In addition, the above springs flywheel diameter of 250mm, all models should be reduced by using highly 300mm.
