电动卷帘门安装质量好不好，差距不在“门有没有装上去”，而在轨道是否垂直、扭簧是否匹配、电机是否过载。这三个问题，明显一个没做好，门用不了多久就会出现卡顿、异响、甚至电机烧毁。

The difference in the installation quality of electric rolling shutter doors is not whether the door is installed or not, but whether the track is vertical, the torsion spring is matched, and the motor is overloaded. If any of these three problems are not handled properly, the door will soon experience lagging, abnormal noise, and even motor burnout.

参数核对：安装前先对8个核心参数，避免“装上去发现不对”

Parameter verification: Before installation, check the 8 core parameters to avoid "finding errors when installing"

很多电动卷帘门故障，根源在安装前就没核对清楚参数。进场安装前，建议确认以下8项：

Many electric rolling shutter door malfunctions stem from the failure to verify the parameters before installation. Before entering the installation site, the following 8 items must be confirmed:

门洞尺寸：宽度、高度、门楣高度，准确到毫米。

Door opening dimensions: width, height, lintel height, accurate to millimeters.

帘片型号与厚度：根据门洞大小匹配55/77/100mm帘片，厚度达标（见上文）。

Curtain model and thickness: Match the 55/77/100mm curtain according to the size of the door opening, and ensure that the thickness meets the standard (see above).

电机功率与电压：家用220V单相、工业380V三相，功率匹配门体重量。

Motor power and voltage: household 220V single-phase, industrial 380V three-phase, power matching door weight.

导轨规格：冷轧钢或铝合金，厚度≥1.5mm，每米垂直度偏差≤1.5mm。

Guide rail specification: Cold rolled steel or aluminum alloy, thickness ≥ 1.5mm, verticality deviation per meter ≤ 1.5mm.

卷轴直径：常用φ76-165mm无缝钢管，壁厚≥2.0mm。

Roller diameter: commonly used seamless steel pipe with a diameter of 76-165mm and a wall thickness of ≥ 2.0mm.

扭簧匹配：建议根据门体准确重量计算扭簧预紧力——这是“门的平衡系统”，直接决定电机负载和门体寿命。

Twist spring matching: The pre tension force of the torsion spring must be calculated based on the precise weight of the door body - this is the "balance system of the door", which directly determines the motor load and door body life.

控制器功能：上/停/下限位精度≤20mm，遥控距离≥30m。

Controller function: Upper/stop/lower limit accuracy ≤ 20mm, remote control distance ≥ 30m.

安全装置：红外对射或安全气囊联动功能，遇阻反弹建议达标。

Safety device: Infrared projection or airbag linkage function, rebound must meet the standard in case of obstruction.

安装调试：扭簧是“隐形的心脏”，调不准电机一年就坏

Installation and debugging: The torsion spring is the "invisible heart", and if not adjusted, the motor will break down within a year

安装中非常关键、也非常容易被忽视的环节是扭簧调试。翻板式车库门的扭簧储存着巨大的能量，建议由专业安装人员根据门体的准确重量现场计算并调试。调试标准很简单：门体在任意位置大多能停住，不会下坠也不会急速上升。扭簧调不准的后果：电机长期过载工作，寿命大幅缩短；门体运行时噪音大；严重时门体下坠，存在安全隐患。注意：严禁用户自行调整扭簧，操作不当出色其危险。

The most critical and easily overlooked step in installation is the adjustment of the torsion spring. The torsion spring of the flip type garage door stores enormous energy and must be calculated and debugged on-site by professional installers based on the precise weight of the door body. The debugging standard is simple: the door can stop at any position without falling or rapidly rising. The consequences of inaccurate adjustment of the torsion spring: long-term overload operation of the motor significantly shortens its lifespan; The noise during the operation of the door is loud; In severe cases, the door may fall, posing a safety hazard. Attention: Users are strictly prohibited from adjusting the torsion spring on their own. Improper operation is extremely dangerous.

日常保养：轨道清灰、铰链润滑、扭簧防锈，每年一次专业检查

Daily maintenance: track cleaning, hinge lubrication, torsion spring rust prevention, professional inspection once a year

电动卷帘门的保养不是“坏了再修”，而是“定期养护”。每月检查：轨道槽内有无杂物、沙尘堵塞；运行时有无异常摩擦声或尖锐声响。每半年：对轨道滚轮、铰链轴等活动部位添加专用润滑脂（非普通机油），对扭簧表面做防锈检查。每年：邀请专业服务商进行多维度检查——紧固所有螺丝、测试安全反转功能、检查电机和控制系统线路。保养小贴士：卷帘门电机和传动链条需经常加注润滑剂；检查控制箱内器件和开关控制盒，紧固接线端口、清洁灰尘。

The maintenance of electric rolling shutter doors is not about "repairing when they break down", but about "regular maintenance". Monthly inspection: Check for debris and dust blockage in the track groove; Is there any abnormal friction or sharp sound during operation. Every six months: Add special lubricating grease (not ordinary engine oil) to moving parts such as track rollers and hinge shafts, and conduct rust prevention inspections on the surface of torsion springs. Every year: Invite professional service providers to conduct comprehensive inspections - tighten all screws, test safety reversal functions, and inspect motor and control system wiring. Maintenance tip: The motor and transmission chain of the rolling shutter door need to be regularly lubricated; Check the components and switch control box inside the control box, tighten the wiring ports, and clean the dust.

一句话总结： 电动卷帘门“三分产品，七分安装”——扭簧精度决定电机寿命，轨道垂直度决定运行顺滑度，安全装置灵敏度决定人车安全。选对产品只完成30%，剩下70%靠安装和保养。

In summary, the electric rolling shutter door is divided into three parts: product, installation. The accuracy of the torsion spring determines the service life of the motor, the verticality of the track determines the smoothness of operation, and the sensitivity of the safety device determines the safety of people and vehicles. Only 30% of the product selection is completed, and the remaining 70% relies on installation and maintenance.
