电动门内进水；

Water inlet in the electric valve;

电动门内进水主要是下雨，雨水从电缆槽内顺着电缆管进电动头内部。如左端下集管排污#2电动门，电动头是奥玛电动门，出现故障为集控室内画面无反馈显示，到就地发现门上三个指示灯同时亮，明显看出是报一个故障信号，可能是力矩故障，但是打手动转动手轮，发现阀门没有被卡住，动作正常，这时推测可能是反馈装置失灵，打开盖子看反馈装置也正常，这时想可能是拨码开关没拨好或电路板问题。当打开另一个盖子时发现电路板拨码开关处存有积水，当断掉电源后，擦干电路板电动头内积水，送电后工作正常。

The water in the electric door is mainly rain. The rain water enters the electric head from the cable trench along the cable pipe. For example, the lower header drain ා 2 electric valve at the left end, the electric head is the Omar electric valve, and if there is a fault, there is no feedback display in the picture in the central control room. It is found that the three indicator lights on the door are on at the same time on the spot. It is obvious that a fault signal is reported, which may be a torque fault. However, turning the hand wheel manually, it is found that the valve is not stuck, and the action is normal. At this time, it is speculated that the feedback device may be out of order, Open the cover to see if the feedback device is normal. At this time, I think it may be that the dial switch is not set properly or the circuit board is faulty. When the other cover is opened, it is found that there is water at the circuit board dial switch. When the power supply is cut off, wipe the water in the electric head of the circuit board dry, and work normally after power transmission.

2、在热态时电动门出现过力矩。

2. In the hot state, the electric door has over torque.

在热态时电动门出现过力矩的较多，主要是热膨胀使阀门卡，高旁压力调节阀出现过力矩现象，到就地打手动转动手轮，发现手动也不吃力，查看开力矩为700NM，最大力矩为1000NM，这时把开力矩定为900NM，但调节阀依然无论在就地还是远方状态都打不开，这时经大调允许把阀门手动操作打开到90%，过了一会远方操作正常，最后得出结论为阀门两边温差、压差太大所致。最后停机后又把开力矩调为最大1000NM，关力矩调为900NM。如果再次起机时依然出现这个问题，就可确定判断该管道使用此种型号的电动调节阀不合理，

In the hot state, the electric valve has more excessive torque, mainly due to the thermal expansion, the valve is stuck, and the high bypass pressure regulating valve has excessive torque. When the hand wheel is turned manually on the spot, it is found that the manual force is not too hard. Check that the opening torque is 700nm, and the maximum torque is 1000nm. At this time, set the opening torque as 900nm, but the regulating valve still cannot be opened in the local or remote state. At this time, after the major adjustment It is allowed to open the valve manually to 90%. After a while, the remote operation is normal. Finally, it is concluded that the temperature difference and pressure difference on both sides of the valve are too large. After the final shutdown, adjust the opening torque to the maximum of 1000nm and the closing torque to 900nm. If this problem still occurs when starting the machine again, it can be determined that the use of this type of electric control valve in the pipeline is unreasonable,
