At present, more and more customers use industrial doors. On the accessories of industrial doors, there is an indispensable part called torsion spring.

扭簧是工业门的一种安装保护装置，它可以防止门体对人或物体造成伤害。让我们来看看扭簧在工业门中的作用。

Torsion spring is an installation protection device of industrial door, which can prevent the door body from causing injury to people or objects. Let's take a look at the role of torsion springs in industrial doors.

工业门使用扭簧的主要作用是为了保持门的平衡，从而能够减轻电机负担，要知道，在工业门的上升过程中，不同上升位置时所用的提升力气会有所差别，这时若没有扭簧，门体提升力气过大，就会将工业滑升门往上穿出其轨道，反之，加入气力较小，电机的提升负荷变大，时间一长

The main function of the torsion spring used in the industrial door is to keep the balance of the door, so as to reduce the burden of the motor. You know, in the rising process of the industrial door, the lifting force used in different rising positions will be different. At this time, if there is no torsion spring, the lifting force of the door body is too large, and the industrial sliding door will go up out of its track. On the contrary, the added force is small, Increase the load of the motor for a long time

电机的使用寿命就会大打折扣，而设置了扭簧的工业门就大大不一样，根据不同位置提升力的区别，扭簧的气力也会随之不同，以便让门体的重量与弹簧的气力相互保持在一个平衡的状态。

The service life of the motor will be greatly reduced, and the industrial door equipped with torsion spring is greatly different. According to the difference of lifting force at different positions, the air force of torsion spring will also be different, so as to keep the weight of door body and the air force of spring in a balanced state.

扭转弹簧的端部装有扭转弹簧保护装置。当扭力弹簧断裂时，保护装置将扭力弹簧和钢丝绳拉近停止滑动。当然，白色客户对工业门的选择与它自身的性能有很大关系。工业门体采用品质优良的材料制成，保温效果好。

The end of the torsion spring is equipped with a torsion spring protection device. When the torsion spring breaks, the protection device pulls the torsion spring close to the steel wire rope to stop sliding. Of course, the choice of white customers for industrial doors has a lot to do with its own performance. The industrial door body is made of high-quality materials with good thermal insulation effect.

门体采用双层镀锌钢板压花成型，中间填充防火保温材料。具有强度好、耐久性好、保温隔音等优点。表面喷塑，防腐效果好。

The door body is embossed with double-layer galvanized steel plate, and the middle is filled with fireproof and thermal insulation materials. It has the advantages of good strength, good durability, thermal insulation and sound insulation. The surface is sprayed with plastic, with good anti-corrosion effect.

门体的四周采用的是密封材料并作密封处理，保温效果好，我司安装的工业门具有防盗的功能，可以较好的保护客户的财产，门体、电机、控制系统合为一体，操作方便。

Sealing materials are used around the door body and sealed, with good thermal insulation effect. The industrial door installed by our company has the function of anti-theft, which can better protect customers' property. The door body, motor and control system are integrated and easy to operate.
