Electric garage door is very common in our life. It looks beautiful and atmospheric, solid and durable. It doesn't need to be opened manually when getting off the car. It's convenient and fast. It's a good choice for many car owners now.

不过有些车库门在使用一段时间后，却出现了开启声音过大的现象，这是什么原因造成的？有何方法来排除呢？

However, some garage doors open too loudly after being used for a period of time. What is the reason? Is there any way to eliminate it?

1、安装不当

1. Improper installation

在安装电动车库门是，由于没有保持在一个水平位置，一边门板靠近轨道，另一边则是远离轨道，这样以来在车库门门体上升过程中门板上的铰链和导轨之间摩擦力变大，就会产生吱吱的噪音。排除是，可以通过调整车库门两侧导轨来保证车库门门板在两侧导轨正中间，如此便不会产生噪音过大问题了。

When installing the electric garage door, because it is not kept in a horizontal position, one side of the door panel is close to the track and the other side is far away from the track. In this way, the friction between the hinge on the door panel and the guide rail becomes larger during the rise of the garage door body, which will produce squeaking noise. The elimination is that the guide rails on both sides of the garage door can be adjusted to ensure that the garage door panel is in the middle of the guide rails on both sides, so that there will be no problem of excessive noise.

2、电动车库门合页、轨道等位置的固定螺丝松动也会造成噪音过大问题的出现，这是需要检查车库门固定合页和导轨的螺丝，看其是否出现松动，如有松动，要用老虎钳拧紧。

2. The loose fixing screws at the hinge and track of the electric garage door will also cause the problem of excessive noise. It is necessary to check the screws of the garage door fixing hinge and guide rail to see if they are loose. If they are loose, tighten them with vice.

3、磨损严重

3. Severe wear

车库门运行滚轮上面塑料脱落、损坏、滚轴磨损严重会导致门板倾斜，倾斜后运行噪音也会变大。因此要定期更换运行滚轮，一定要全部更换，不过不要使用铁滚轮，铁滚轮需要经常加润滑油，而且铁滚轮运行是有声音的，所以建议大家使用品质优良的尼龙滚轮。

The plastic on the running roller of the garage door falls off, is damaged, and the roller is seriously worn, which will cause the door panel to tilt, and the running noise will become larger after tilting. Therefore, the running rollers should be replaced regularly, and all of them must be replaced. However, do not use the iron roller. The iron roller needs to be lubricated frequently, and the iron roller runs with sound, so it is recommended to use high-quality nylon roller.

4、部件缺油

4. Component oil shortage

在济南电动车库门的导轨、平衡系统和扭簧连接的传动部件少油时，运行的噪音也会很大，所以建议大家要定期给传动部件、导轨添加润滑油，以保证门体的运行顺畅。

When there is little oil in the guide rail, balance system and transmission parts connected with torsion spring of Jinan electric garage door, the operation noise will also be great. Therefore, it is suggested that you should regularly add lubricating oil to the transmission parts and guide rail to ensure the smooth operation of the door body.
