电动卷帘门噪音如何？

How to eliminate the noise of electric rolling shutter door? One is to replace the tooth surface of roller gate with smooth tooth surface to avoid excessive friction and noise. The second is to adopt the gear with good accuracy, which avoids the error rate of pitch, tooth profile, tooth groove and tooth rib, and effectively reduces the noise. Third, it can be used for lubrication. In order to eliminate the noise of the rolling gate, a proper amount of lubricating oil is dripped into the axle and saw teeth regularly. Fourth, the tooth width can be widened, especially the high stiffness tooth profile can reduce the noise.

一、如何选择卷帘门

1、 How to choose rolling shutter door

1、看看材料

1. Look at the material

市场上卷帘门的材料很多，如铝合金、彩钢板、格栅、水晶、PVC、不锈钢等。铝合金卷帘门比较常见，外观好，，但使用噪音大。彩钢板卷帘门具有丰富的色彩性能，可适用于各种门板。格栅卷帘门具有这种很好的通风、透光的优点，而且在防盗、装饰性能上也不错。

There are many materials for rolling shutter doors in the market, such as aluminum alloy, color steel plate, grille, crystal, PVC, stainless steel, etc. Aluminum alloy shutter door is more common, good appearance, environmental protection, but the use of noise. Color steel rolling shutter door has rich color performance, which can be applied to all kinds of door panels. The grill shutter door has the advantages of good ventilation and light transmission, as well as good anti-theft and decorative performance.
       

2、看看功能

2. Look at the features

市场上卷帘门主要分为手动和电动两种。其中，电动卷帘门比较流行，但在选购时要注意它是否具有手动功能，否则，一旦停电，就不能使用，这会造成很大的不便。

Roller shutter door on the market is mainly divided into manual and electric two. Among them, the electric roller shutter door is more popular, but in the purchase should pay attention to whether it has manual function, otherwise, once the power failure, it can not be used, which will cause great inconvenience.

3、看看这个结构

3. Look at the structure

采购时，结构不可忽视。精 密全齿轮旋转结构更好，不易断链、断带等，同时配备散热快的电机。

When purchasing, structure cannot be ignored. Precision full gear rotation structure is better, not easy to break chain, broken belt, etc., at the same time equipped with fast heat dissipation motor.

二、 卷帘门噪声源
