故障情况一：肯德基门闭合不紧密

Fault condition 1: KFC door is not tightly closed

故障详细分析：肯德基门开启后，门扇闭合不严密，有宽度0.1cm以上的缝隙。这种情况产生原因主要由于闭门器使用频繁、维护不及时或者闭门器本身质量问题都会产生这种情况。如果是前两个原因造成的可以通过调闭门器关闭力度以达到维修目的，如果是产品质量问题通过更换闭门器即可。

Detailed fault analysis: after the KFC door was opened, the door leaf was not closed tightly, and there was a gap with a width of more than 0.1cm. This situation is mainly caused by frequent use, untimely maintenance or quality problems of the door closer itself. If it is caused by the first two reasons, it can be repaired by adjusting the closing force of the door closer. If it is a product quality problem, it can be solved by replacing the door closer.

故障情况二：肯德基门门扇下垂

Fault condition 2: KFC door leaf sagging

故障详细分析：肯德基门门扇下垂，出现摩擦地面的现象。这种情况可以从地轴寻求方法。安装技术不到位、地轴承重量小于门扇重量、地轴本身质量问题都会产生这种情况。如果是后两个原因造成的，只能通过更换地轴问题，如果是因为安装技术问题导致的，可以通过砸地轴以达到维修目的。

Detailed fault analysis: KFC door leaf sagged and rubbed the ground. This situation can be solved from the earth axis. The installation technology is not in place, the weight of the ground bearing is less than the weight of the door leaf, and the quality problem of the ground shaft itself will cause this situation. If it is caused by the latter two reasons, the problem can only be solved by replacing the ground shaft. If it is caused by installation technical problems, the maintenance purpose can be achieved by smashing the ground shaft.

济南肯德基门厂家在维修肯德基门的过程中，发现还有一种常见的因素导致的门下垂，就是调节螺丝因退丝造成门下垂，探索的维修办法是通过用内六角扳手调节两边的地轴达到门的升降，顺时针为上升，逆时针为下降，用这种方法对信都第五营业室门进行维修，避免更换配件，有效降低了运维成本。

In the process of maintaining the KFC door, the manufacturer of Jinan KFC door found that there was another common factor causing the door to sag, that is, the adjusting screw caused the door to sag due to thread withdrawal. The maintenance method explored was to use an Allen wrench to adjust the floor shafts on both sides to achieve the lifting and lowering of the door. The needle rose in time and fell in anticlockwise. This method was used to repair the door of the fifth business room of Xindu, avoiding the replacement of parts, and effectively reducing the operation and maintenance cost.

此外肯德基门常出现的一个问题便是下沉，原因有很多种，而且根据不同材质、款式的门，调整方法也不一样。以铁管焊接防盗门为例，具体调整方法有：

In addition, a common problem of KFC doors is sinking. There are many reasons, and the adjustment methods are different according to different materials and styles of doors. Taking the iron pipe welded anti-theft door as an example, the specific adjustment methods are as follows:

如果是门铰链上的螺丝松动造成的，那就可以在门往上托起的情况下紧固螺丝，可以先把门的所有螺丝都拧松了，然后把门托起到合适的高度，再把所有螺丝都紧固。

If it is caused by the loose screws on the door hinge, you can tighten the screws when the door is lifted up. You can loosen all the screws of the door first, then lift the door to a proper height, and then tighten all the screws.

如果是门铰链本身质量不好，材质较薄，在门的重力作用下铰链变形的话，那么就直接换一副质量好点、材质较厚的铰链即可。如果门框本身有些变形，那修复起来就比较麻烦了，可以叫物业或其他人员来修。

If the door hinge itself is poor in quality and thin in material, and the hinge is deformed under the gravity of the door, it can be directly replaced with a pair of hinges with better quality and thicker material. If the door frame itself is deformed, it will be troublesome to repair. You can call the property management or other professionals to repair it.
