First of all, whether it is a dust-free workshop or a constant temperature and humidity workshop, how to ensure the normal flow of personnel, machines and goods, and achieve the purpose of isolation and protection to a large extent. The soft fast rolling shutter door has an intelligent automatic fast switch and security system, so as to ensure the normal flow and speed of personnel and goods.

軟質快速卷簾門的快捷性能阻止了內外的空氣對流，保證了車間內部溫濕度的穩定（節省能源），阻止了昆蟲、灰塵等有害物質的侵入，保護內部環境衛生。

The fast performance of the soft fast rolling shutter door prevents the internal and external air convection, ensures the stability of temperature and humidity in the workshop (saving energy), prevents the invasion of insects, dust and other harmful substances, and protects the internal environmental sanitation.

可以看出，在恒溫恒濕、無粉塵的車間安裝快速卷簾門是非常必要的。隨著對食品、藥品、加工等領域對工作環境的要求是越來越高，作為企業家，無論是對食品的責任，還是對其自身產品質量的要求，都會對快速卷簾門有的認同和選擇。

It can be seen that it is very necessary to install fast rolling shutter door in the workshop with constant temperature and humidity and no dust. As the country's requirements for the working environment in the fields of food, medicine and processing are becoming higher and higher, as entrepreneurs, they will recognize and choose the fast rolling shutter door whether it is their responsibility for food or their own product quality.

快速卷簾門產品，隨之國內不僅發展很快，現已比肩國外同行，而且質量很好。雄偉牌快速卷簾門已成為國內外企業車間內部使用的設備。

Fast rolling shutter door products, with the rapid development of domestic brands, are now comparable to foreign counterparts, and the quality is very good. Majestic brand fast rolling shutter door has become an internal equipment used in workshops of enterprises at home and abroad.

卷簾門是以門上方卷軸為轉動上下的門，一般很多商鋪會用到，它在關閉的時候一定程度上是依賴自重來完成的，然而有時候卻會有自重下降不起作用的情況，這是為什么呢？

The roller shutter door is a door that rotates up and down with the scroll above the door. It is generally used by many shops. It depends on self weight to a certain extent when it is closed. However, sometimes the decline of self weight does not work. Why?

1、卷簾門手動拉桿變形。門手動拉桿遇到意外撞擊或用力過大時，容易變形。手動拉桿一旦變形，會導致高速門自重失去作用此時需要更換手動拉桿，更換后問題就了。

1. The manual pull rod of roller shutter door is deformed. The manual pull rod of the door is easy to deform in case of accidental impact or excessive force. Once the manual pull rod is deformed, the self weight of the high-speed door will lose its function. At this time, the manual pull rod needs to be replaced. After replacement, the problem is solved.

2、門拉桿和墊圈之間的間隙變大，這種原因也會導致卷簾門失去自身重量。在處理這個問題時，只需要將擴大的縫隙縮小到合適的位置，當自重下降時就會出現作用。

2. The gap between the door pull rod and the washer becomes larger, which will also cause the rolling shutter door to lose its own weight. When dealing with this problem, we only need to narrow the expanded gap to a suitable position, which will play a role when the self weight decreases.

3、齒輪箱電機潤滑失效。如果檢查意識到是這個原因讓門自重不起作用的，那就意味著有必要更換電機變速箱的潤滑脂。

3. Gearbox motor lubrication failure. If the inspection realizes that the self weight of the door does not work for this reason, it means that it is necessary to replace the grease of the motor gearbox.

卷簾門在使用過程中如果出現以上問題，則就會導致卷簾門自重下降不起作用，這時候要抓緊時間維修處理，否則則會影響正常的使用。

If the above problems occur during the use of the rolling shutter door, the self weight of the rolling shutter door will drop and will not work. At this time, it is necessary to seize the time for maintenance, otherwise it will affect the normal use.
