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、如何選擇卷簾門

1、 How to choose rolling shutter door

1、看看材料

1. Look at the material

市場(chǎng)上卷簾門的材料很多，如鋁合金、彩鋼板、格柵、水晶、PVC、不銹鋼等。鋁合金卷簾門比較常見，外觀好，，但使用噪音大。彩鋼板卷簾門具有豐富的色彩性能，可適用于各種門板。格柵卷簾門具有這種很好的通風(fēng)、透光的優(yōu)點(diǎn)，而且在防盜、裝飾性能上也不錯(cuò)。

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

市場(chǎng)上卷簾門主要分為手動(dòng)和電動(dòng)兩種。其中，電動(dòng)卷簾門比較流行，但在選購(gòu)時(shí)要注意它是否具有手動(dòng)功能，否則，一旦停電，就不能使用，這會(huì)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、看看這個(gè)結(jié)構(gòu)

3. Look at the structure

采購(gòu)時(shí)，結(jié)構(gòu)不可忽視。精 密全齒輪旋轉(zhuǎn)結(jié)構(gòu)更好，不易斷鏈、斷帶等，同時(shí)配備散熱快的電機(jī)。

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、 卷簾門噪聲源

2、 Noise source of rolling shutter door

1、PVC卷簾門底部與地面接觸時(shí)產(chǎn)生的噪音。

1. The noise generated when the bottom of PVC rolling shutter door contacts with the ground.

2、齒輪轉(zhuǎn)動(dòng)時(shí)摩擦產(chǎn)生的機(jī)械噪音。

2. The mechanical noise caused by friction when the gear is rotating.

3、窗簾與卷簾門邊緣摩擦產(chǎn)生的噪音。

3. Noise caused by friction between curtain and rolling door edge.

4、窗簾片之間的碰撞和摩擦產(chǎn)生的噪音。

4. Noise caused by collision and friction between curtain panels.
