电动伸缩门的故障维修方法。
Troubleshooting methods for electric telescopic doors.
一、电动门驱动故障维修。操作过程中的抖动主要是由于制动杆的长度（重量）与弹丸拉力之间的不平衡造成的。如果下杆不颤动，杆就会颤动，这意味着箭的拉力太大。只要松开弹簧拉力，上杆就不会颤动，而下杆则不会颤动，因为弹簧拉力不足，应拧紧或更换拉簧。对于高压元件，如可控硅整流器和高压区域的元件，应在断电前通电一段时间，断电后迅速接触，通电时不要触摸，以免发生触电事故。
1、 Repair the power door drive malfunction. The shaking during operation is mainly caused by the imbalance between the length (weight) of the brake rod and the tensile force of the projectile. If the lower pole does not vibrate, the pole will vibrate, which means that the pull of the arrow is too great. As long as the spring tension is released, the upper rod will not vibrate, while the lower rod will not vibrate because the spring tension is insufficient, and the tension spring should be tightened or replaced. For high-voltage components, such as thyristor rectifiers and components in high-voltage areas, they should be powered on for a period of time before power outage, and quickly contacted after power outage. Do not touch them during power on to avoid electric shock accidents.
二、电动门 门体故障维修对开门自动反转是由于红外抗干扰能力差或对开门辐射感应导致的误操作。通常，采用编码或更换。PCB板也可用于过滤红外输出继电器的驱动三极管，并在其极处使用47uf电解电容器外部干扰。现在使用的通用电路分为A和B两种，电路中的信号通道处理不需要再次编码，但A和B版本应一起用于车门打开。
2、 The automatic reversal of the electric door body during maintenance is due to poor infrared anti-interference ability or misoperation caused by radiation induction of the door opening. Usually, encoding or replacement is used. PCB boards can also be used to filter the driving transistor of infrared output relays and use 47uf electrolytic capacitors at their poles for external interference. The general circuits currently used are divided into two types: A and B. The signal channel processing in the circuit does not require further encoding, but versions A and B should be used together for door opening.
三、电动门控制系统故障维护 不能切换到检查工具和保险管是否有烧,如果保险丝坏了,要做一个全面检查。可以开关,电机线没有问题,红、白、黄线信号线路短路。主要原因是限制不是发送到控制信号系统或控制器限制功能不好。不能自动停止:
3、 The fault maintenance of the electric door control system cannot be switched to checking whether the tools and safety tubes are burned. If the fuse is broken, a comprehensive inspection should be conducted. It can be turned on and off, there is no problem with the motor wire, and the red, white, and yellow signal lines are short circuited. The main reason is that the restriction is not sent to the control signal system or the controller's restriction function is not good. Cannot automatically stop:
1、限制传感器K1, K2和开放(限制磁传型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵感器一个封闭的,没有磁场断开);
1. Limit sensors K1, K2, and open (limit the magnetic sensor to a closed one without magnetic field disconnection);
2、公共蓝线开路。
2. The common blue line is open.
