1、外观 —— 首先对产品外观进行观察，自动门主要构成有运行轨道、传动机构、控制主板、电源、电机等几大部分，先看看这些主要部件外观工艺如何，轨道表面处理是否平直光滑，主板、电机等外观加工工艺情况，最重要一点，看看连接电线的布局状况，是井井有条还是杂乱无章，就如看汽车，打开前盖，看里面是一团乱麻还是简洁明了，往往就是一辆汽车档次高低的分野，自动门也一样。
1, the first appearance - the appearance of the product was observed. The automatic door is mainly composed of an orbit, a transmission mechanism, control board, power supply, motor and other parts, to see how the appearance of the process of these major components, the track surface treatment is flat and smooth, motherboard, electric machine appearance processing technology, the most important point, see the layout of the connecting wire is arranged in good order, or out of order, such as automobiles, open the front cover, inside is a mess or concise, often is a car grade level of the division, as well as automatic door.

2、运行 —— 看看机器运行起来是否平稳、顺畅，从侧面目测挂架轮组走起来会不会摇摆或跳动。听听声音，是否安静，噪音大不大，有没有分辨不出声音来源的杂音，噪音高低是区分自动门品质高低的一个重要指标，因为一款自动门从设计到制作各项指标有没有达到高水准，决定自动门最终出来的运行结果，而噪音可以直接反应出系统运行过程中存在的问题，只有各系统配合精良，运作正常，才会没有噪音，这是很难做到的，所以说，一台运行安静的自动门，就可以断定是一台高档自动门，当然，自动门应该是在有负载的情况下测试，而不是空载的情况下。
2, run - see whether the machine is running smoothly and smoothly, from the side to watch the hanger wheel group walk up will not swing or jump. Listen to the voice of the quiet, noise big, did not distinguish the sound sources of noise, the noise level is an important index to distinguish the quality of the automatic door, because an automatic door from design to production indicators have reached the high level, the operation results of automatic door out of the final decision, and the noise can be direct response to problems in the process of system operation, only the system with excellent operation, only there is no noise, it is difficult to do, so that a quiet operation of automatic doors, it can be concluded that is a high-grade automatic door automatic door, of course, should be in the case of a load the test, rather than under the condition of no-load.
