车库门开启声音响是怎么回事？

1. Apply lubricating oil on the side hinges of the garage door panel. Pay special attention to the side corresponding to the hinge and track and the inside of the hinge hole.

2、更换运行在导轨中的滚轮，注意一定要全部更换，滚轮上面塑料脱落，损坏，滚轴磨损严重是导致门板倾斜的重要原因，并且滚轮的使用寿命都是一样的，今天这几个坏了，其他的使用寿命也查不多了！但是外观不一定的看的出来，滚轮里面的轴承实际已经磨损很严重了，所以滚轮一定要全部更换。建议不要使用铁滚轮，铁滚轮需要经常加润滑油，而且铁滚轮运行是有声音的，所以一定要使用尼龙滚轮，尼龙滚轮耐高温和低温，耐磨损，使用寿命长，而且噪音很低！新安装的滚轮表面、滚轮轴和内部的钢球也加一些润滑油，以确保充分的流程运行！

2. Replace the rollers running in the guide rail. Be sure to replace them all. The plastic on the rollers falls off and is damaged. The serious wear of the rollers is an important reason for the inclination of the door panel, and the service life of the rollers is the same. Today, these rollers are broken, and there are not many other service lives! However, the appearance is not necessarily obvious. The bearings in the roller have been seriously worn, so the roller must be replaced completely. It is recommended not to use the iron roller. The iron roller needs to be lubricated frequently, and the iron roller runs with sound, so we must use the nylon roller. The nylon roller is resistant to high and low temperature, wear resistance, long service life and low noise! The newly installed roller surface, roller shaft and internal steel ball are also lubricated to ensure sufficient process operation!

3、导轨里面加润滑油

3. Add lubricating oil into the guide rail

4、车库门平衡系统即和扭簧连接的部件加润滑油

4. The garage door balance system, that is, the parts connected with the torsion spring, are lubricated

5、调节车库门平衡系统，上紧钢丝绳等

5. Adjust the garage door balance system, tighten the steel wire rope, etc

6、更换磨损严重的铰链，注意更换的时候和其对应的一起更换，全部换掉，因为每个厂商每个合页的规格都不一样，选错规格，会导致安装出问题！

6. Replace the severely worn hinges. Pay attention to replace them together with their corresponding ones, because the specifications of each hinge of each manufacturer are different. Selecting the wrong specification will lead to installation problems!
