    电动卷帘门该怎么检查维修你知道吗?
    来源:http://www.xlmygs.com  日期:2019-01-22 14:54:34
    电动伸缩门的电路控制系统主要包括:操作按键盒,以CPU为核心的控制主板,遥控器及一些传感器构成的检测控制电路等。在伸缩门的维修中常用的基本方法可概括为:一问、二看、三听、四摸、五测,下面详细介绍一下:
    The circuit control system of electric telescopic door mainly includes: operation of key box, control motherboard with CPU as the core, detection and control circuit composed of remote controller and some sensors, etc. The basic methods commonly used in the maintenance of telescopic doors can be summarized as follows: one question, two views, three listens, four touches and five measurements.
    一问:即询问,在与客户沟通时,先问清机型,品名,损坏原因,故障现象,再据此详细分析,以便做到有的放矢,对症下药,少走弯路。
    Question: That is to say, when communicating with customers, first ask about the model, name, cause of damage, fault phenomenon, and then analyze in detail, so as to achieve targeted, prescribe the right medicine, and avoid detours.
    主要询问的内容有:
    The main questions are as follows:
    何时损坏,是否浸水,是否受过撞击,是否电压过高,是否有人改动,是否操作不当,是否遭受雷击,是否有冒烟现象,是否有异常响声等。
    Whether it is damaged, immersed, impacted, overvoltage, altered, improperly operated, lightning struck, smoking, abnormal noise, etc.
    只有在问明原因后,才能确定下一步的检修方法及处理措施。对于雷击、浸水、冒烟、烧保险等故障机型,切不可贸然通电试机,否则将造成机器再次受创、故障扩大。
    Only after the reasons are ascertained can the next repair methods and treatment measures be determined. For lightning stroke, water immersion, smoke, fire insurance and other fault models, we must not rush to power the test machine, otherwise the machine will be damaged again, the fault will expand.
    二看:即观察,打开伸缩门控制外壳后,应仔细查看电路板上是否有元件受损。如元件断裂、发黑发黄、引脚相碰、器件松动、连线错误等。有经验的维修人员会根据用户提供的相关信息及故障现象,准确地察看伸缩门可疑部位,麻利地找出故障所在。某些接触不良的故障,可在光线较暗处观察可疑部件是否有火花产生来确定

    Second look: that is to say, after opening the control shell of the telescopic door, we should carefully check whether there is any component damage on the circuit board. Such as component breakage, blackening and yellowing, pin contact, device loosening, wiring errors, etc. Experienced maintenance personnel will accurately inspect the suspicious parts of the telescopic door according to the relevant information and fault phenomena provided by users, and quickly find out the fault location. Certain faults with poor contact can be determined by observing sparks in suspicious parts in darker light.

    三听:即听声,在控制系统中,大都采用了电磁继电器作为控制器件,在继电器触点切换时会产生清晰的“滴哒”声。如无声或异常,在确定继电器驱动电器无故障后,可判定该继电器不良。

    Three listeners: that is, listening. In the control system, electromagnetic relays are mostly used as control devices. When the contacts of relays are switched, a clear "drip" sound will be produced. If it is silent or abnormal, it can be judged that the relay is not good after confirming that the relay driver is fault-free.

    四摸:即触摸,在伸缩门的维修过程中,也经常在通电后用手摸(鼻嗅)某些元件。如稳压IC等集成器件、防雷管、变压器、驱动二极管等等,以便感觉其温度是否正常,如发热快、温度高、电路无短路故障则可断定器件不良(注意:对于高电压的元件如可控硅、高压区的元器件,应通电一段时间再断电后迅速触摸,切勿通电时触摸,避免触电事故)。
    Four Touches: Touch, in the process of repairing the telescopic door, also often touch (nose sniff) some components by hand after electrification. For example, integrated devices such as voltage stabilized IC, detonators, transformers, driving diodes and so on, in order to feel whether their temperature is normal, such as fast heating, high temperature, no short circuit fault in the circuit can determine that the device is bad. (Note: For high voltage components such as thyristor, high voltage area components, should be switched on for a period of time and touch quickly after power off, do not touch when power on, to avoid electric shock accident.)
    五测:即测量,指使用万能表拧到合适档位,对控制电路进行相关测量。通常采用的方式有测电压、测电路的电阻、测电流等。这是一种综合性逻辑分析手段,可依据各种测量电动伸缩门的数据准确的找出故障原因及损坏器件。
    Five measures: that is, measurement, refers to the use of universal meters screwed to the appropriate gear, the control circuit for relevant measurement. Usually, there are voltage measurement, circuit resistance measurement, current measurement and so on. This is a comprehensive logical analysis method, which can accurately find out the cause of failure and damage devices based on the data of various measurements of electric telescopic doors.
