卷帘门安装看似简单，但细节决定成败。安装不当，门体运行卡顿、噪音大、寿命短。以下从安装到保养，一次讲清楚。

The installation of rolling shutter doors may seem simple, but the details determine success or failure. Improper installation can cause the door to run slowly, produce loud noise, and have a short lifespan. From installation to maintenance, explain it clearly in one go.

安装前的准备工作。安装前建议对门洞口尺寸进行现场实测，复核卷帘门各部分尺寸是否匹配。根据建筑工程给定的地平线以上1米位置，用水平尺在门洞两边定位划线。检查导轨长度是否正确，导轨长度和开启高度应在合理尺寸范围内。同时检查导轨、支架的预埋位置和数量是否正确。

Preparation work before installation. Before installation, the size of the door opening must be measured on site to verify whether the dimensions of each part of the rolling shutter door match. According to the position 1 meter above the horizon given by the construction project, use a level ruler to mark the line on both sides of the door opening. Check if the length of the guide rail is correct, and the length and opening height of the guide rail should be within a reasonable size range. At the same time, check whether the pre embedded positions and quantities of the guide rails and brackets are correct.

安装的核心步骤。第一步，在门洞上标记出安装位置。第二步，根据门洞高度在两侧墙面安装导轨支架，确保其水平。第三步，将导轨插入导轨支架中并用螺丝固定。安装时要注意两条导轨建议在同一水平线上。卷帘门有内装和外装两种方式——内装即卷帘门装在门洞内，帘片向内侧卷起；外装即卷帘门装在门洞外，帘片向外卷起。两种方式各有适用场景，需根据现场条件选择。

The core steps of installation. The first step is to mark the installation position on the door opening. Step two, install guide rail brackets on both sides of the wall according to the height of the door opening, ensuring that they are level. Step three, insert the guide rail into the guide rail bracket and secure it with screws. During installation, it is important to note that the two guide rails must be on the same horizontal line. There are two ways to install a rolling shutter door: interior installation and exterior installation. Interior installation means that the rolling shutter door is installed inside the door opening, and the curtain is rolled up inward; Externally, the rolling shutter door is installed outside the door opening, with the curtain rolled outward. Both methods have their own applicable scenarios and need to be selected based on the site conditions.

限位调试是关键环节。安装完毕后，向下垂直拉动手动链条，使门片离地面约1米。接通电源及控制器，测试“上”“下”“停”按键，观察卷帘门各功能是否灵敏可靠。将卷帘门开到合适位置后，旋转限位器上的限位螺母，使其压住开门限位开关上的滚轮，听到“嘀嗒”声后即完成限位设置。限位调试不到位，门体可能过卷或撞击地面，损伤门体或电机。

Limit debugging is a crucial step. After installation, pull the manual chain vertically downwards to lift the door panel about 1 meter off the ground. Connect the power and controller, test the "up", "down", and "stop" buttons, and observe whether the functions of the rolling shutter door are sensitive and reliable. After opening the rolling shutter door to the appropriate position, rotate the limit nut on the limiter to press down on the roller on the door opening limit switch. After hearing the "beep" sound, the limit setting is completed. If the limit adjustment is not in place, the door may be rolled over or hit the ground, damaging the door or motor.

日常保养的四个核心。

The four key points of daily maintenance.

导轨润滑：卷帘门的滑轨是门体上下运行的关键部件，定期润滑可减少摩擦、延长寿命。应使用专用润滑油或润滑脂，避免使用普通机油——普通机油易吸附灰尘，导致滑轨堵塞。对导轨滑槽、卷轴轴承、电机传动轴等运动部件，建议涂抹耐高温润滑脂，每3个月润滑一次。

Lubrication of guide rail: The guide rail of the rolling shutter door is a key component for the up and down movement of the door body. Regular lubrication can reduce friction and extend its service life. Special lubricating oil or grease should be used to avoid using ordinary engine oil - ordinary engine oil can easily adsorb dust and cause blockage of the slide rail. For moving parts such as guide rails, roller bearings, and motor drive shafts, it is recommended to apply high-temperature resistant grease and lubricate them every 3 months.

导轨清洁：用软毛刷或吸尘器清理导轨内部及门板表面的灰尘杂物，避免使用尖锐工具刮伤门板。若导轨内有积水，用干布擦干，防止生锈。

Guide rail cleaning: Use a soft bristled brush or vacuum cleaner to clean the dust and debris inside the guide rail and on the surface of the door panel, avoiding scratching the door panel with sharp tools. If there is water accumulation inside the guide rail, dry it with a dry cloth to prevent rusting.

手动装置检查：每月检查手动拉链是否能正常拉动，拉链应无断裂、卡顿现象。手动速放装置应操作灵活。

Manual device inspection: Check monthly whether the manual zipper can be pulled normally, and the zipper should not be broken or stuck. The manual quick release device should operate flexibly.

电机运行检查：每月检查电机运行状态，记录运行噪音、升降速度等数据。发现异常及时处理，避免小问题拖成大故障。季度保养建议拆解传动轴承润滑、校正导轨垂直度。

Motor operation inspection: Check the motor operation status every month, record data such as operating noise and lifting speed. Promptly handle any abnormalities to prevent minor issues from escalating into major malfunctions. Quarterly maintenance recommendations include disassembling the transmission bearings for lubrication and correcting the verticality of the guide rails.
