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

扭簧是工業門的一種安裝保護裝置，它可以防止門體對人或物體造成傷害。讓我們來看看扭簧在工業門中的作用。

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.

工業門使用扭簧的主要作用是為了保持門的平衡，從而能夠減輕電機負擔，要知道，在工業門的上升過程中，不同上升位置時所用的提升力氣會有所差別，這時若沒有扭簧，門體提升力氣過大，就會將工業滑升門往上穿出其軌道，反之，加入氣力較小，電機的提升負荷變大，時間一長

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

電機的使用壽命就會大打折扣，而設置了扭簧的工業門就大大不一樣，根據不同位置提升力的區別，扭簧的氣力也會隨之不同，以便讓門體的重量與彈簧的氣力相互保持在一個平衡的狀態。

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.

扭轉彈簧的端部裝有扭轉彈簧保護裝置。當扭力彈簧斷裂時，保護裝置將扭力彈簧和鋼絲繩拉近停止滑動。當然，白色客戶對工業門的選擇與它自身的性能有很大關系。工業門體采用品質優良的材料制成，保溫效果好。

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.

門體采用雙層鍍鋅鋼板壓花成型，中間填充防火保溫材料。具有強度好、耐久性好、保溫隔音等優點。表面噴塑，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.

門體的四周采用的是密封材料并作密封處理，保溫效果好，我司安裝的工業門具有防盜的功能，可以較好的保護客戶的財產，門體、電機、控制系統合為一體，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.
