Commissioning method and precautions of electric door

一、外观检查：

1、 Visual inspection:

电动阀门及配电箱应完好无损、无锈蚀和划迹，电机上铭牌标志应清楚并符合设计。配电箱内的断路器、接触器及热继电器应符合设计且满足电机容量的要求。并具放完电缆接好线。

The electric valve and distribution box shall be intact, free of rust and mark, and the nameplate mark on the motor shall be clear and conform to the design. The circuit breaker, contactor and thermal relay in the distribution box shall meet the requirements of design and motor capacity. Put out the cable and connect the cable.

二、绝缘检查及电机检查：

2、 Insulation inspection and motor inspection:

1、绝缘检查：电机绝缘应大于0.5MΩ（用500V兆欧表）。

1. Insulation inspection: the motor insulation shall be greater than 0.5m Ω (500V megger is used).

2、电机检查：电机线圈三相电阻应平衡（万用表）。

2. Motor inspection: the three-phase resistance of motor coil shall be balanced (multimeter).

三、阀门检查：

3、 Valve inspection:

检查阀门内部限位机构有无缺损、锈死现象，位置开关动作可靠。并在机务研磨班的配合下，检查阀门在手动开、关阀门时有无卡涩现象。

Check whether the internal limit mechanism of the valve is damaged or rusted, and the position switch operates reliably. With the cooperation of the maintenance grinding team, check whether the valve is jammed when it is opened and closed manually.

四、操作回路试验：

4、 Operation loop test:

1、认真审阅设计院的相关图纸，根据图纸的要求对控制回路进行检查校线，并检查每根连接导线是否连接牢固、可靠。

1. Carefully review the relevant drawings of the Design Institute, check and calibrate the control circuit according to the requirements of the drawings, and check whether each connecting wire is connected firmly and reliably.

2、  检查电动阀门配电箱〔抽屉〕内的断路器是否符合设计要求，并根据电机的额定电流调整热继电器的电流值。

2. Check whether the circuit breaker in the electric valve distribution box [drawer] meets the design requirements, and adjust the current value of the thermal relay according to the rated current of the motor.

3、合上控制回路电源（断开动力回路电源），〔将有抽屉送至工作位置〕将位置开关选至就地，试验操作回路动作是否正确（包括开、关控制回路，开、关闭锁回路，闪光回路，灯回路，过力矩闭锁保护）；再将位置开关选至远操位置，在集控室内DCS上操作（包括开、关控制回路，信号反馈回路，过力矩闭锁保护）。

3. Turn on the control circuit power supply (disconnect the power circuit power supply), [send the drawer to the working position], select the position switch to the local position, test whether the operation circuit acts correctly (including opening and closing the control circuit, opening and closing the lock circuit, flashing circuit, light circuit, over torque locking protection); then select the position switch to the far operation position, and operate on the DCS in the central control room (including Open and close control circuit, signal feedback circuit, over torque locking protection).

五、动力回路试验及阀门调整：

5、 Power circuit test and valve adjustment:

1、合上控制回路及动力回路电源，〔将有抽屉送至工作位置〕将位置开关选至就地，手动阀门至中间位置，操作开阀或关阀按钮检查电机及阀门转向是否正确。

1. Close the power supply of the control circuit and power circuit, [send the drawer to the working position], select the position switch to the local position, manually operate the valve to the middle position, and operate the open or close valve button to check whether the motor and valve are turning correctly.

2、将关阀力矩调至最小，操作关阀按钮，将阀门关至关力矩动作，在研磨班人员的配合下，往开方向行走1－1.5圈，此时调整关中断使其动作。再根据阀门所处系统将关力矩调整到合适位置（一般高压系统调至7－9位置；低压系统调至5－7位置）。

2. Adjust the valve closing torque to the minimum, operate the valve closing button, close the valve to the closing torque action, walk 1-1.5 circles towards the opening direction with the cooperation of the grinding team personnel, at this time adjust the closing interruption to make it act. Then adjust the closing torque to the appropriate position according to the system where the valve is located (generally, the high-pressure system is adjusted to 7-9 position; the low-pressure system is adjusted to 5-7 position).

3、将开力矩调至最小，操作开阀按钮，将阀门开至开力矩即要动即作即可，检查阀杆开度与阀门行程是否合适，检查合适后，再往关方向行走1-2圈，此时调整开中断使其动作，再将开力矩调至大于关力矩值1-2的位置。

3. Adjust the opening torque to the minimum, operate the valve opening button, open the valve to the opening torque, and then operate it immediately. Check whether the valve stem opening and valve travel are appropriate. After the inspection is appropriate, walk 1-2 circles towards the closing direction. At this time, adjust the opening interruption to make it operate, and then adjust the opening torque to a position greater than the closing torque value 1-2.

4、调整阀门位置指示合适的变速齿轮，使阀门的就地位置指示与阀门的实际位置吻合。

4. Adjust the valve position to indicate the appropriate variable speed gear, so that the local position indication of the valve is consistent with the actual position of the valve.

5、电动阀门如果是可调整门，调整好上述步骤后，还需要对阀门的开度指示进行调整，调节位置发送器，使配电箱以及DCS上显示的开度指示与阀门的实际位置相吻合。

5. If the electric valve is an adjustable valve, after the above steps are adjusted, the opening indication of the valve shall be adjusted, and the position transmitter shall be adjusted to make the opening indication displayed on the distribution box and DCS coincide with the actual position of the valve.

6、阀门完整行走一次，记录其开、关行程的时间。再将位置开关选至“程控”位置，在DCS上操作一次，观察DCS上的指示是否完全正确。最后将阀门运行到关完位置。

6. The valve shall be fully operated once, and the time of opening and closing stroke shall be recorded. Then select the position switch to "program control" position, operate once on DCS, and observe whether the indication on DCS is completely correct. Finally, operate the valve to the closed position.

7、调试完毕，断开其控制回路及动力回路电源〔将有配电箱抽屉拔出〕。将电动头卸下的各部分部件恢复，作好标识（包括调试人员，调试时间）。在DCS上设置“禁操”。将其处于备用状态。保存好原始记录。

7. After commissioning, disconnect the power supply of control circuit and power circuit [pull out the drawer of distribution box]. Recover all parts removed from the electric head and make marks (including debugging personnel and debugging time). Set "no operation" on DCS. Put it in standby state. Keep the original records.

六、安全文明施工措施：

6、 Safe and civilized construction measures:

1、调整前应确认被调整的阀门所处的系统处于停运状态，且与其它有压容器完全隔离。保证系统安全。

1. Before adjustment, it shall be confirmed that the system of the adjusted valve is in shutdown state and completely isolated from other pressure vessels. Ensure system safety.

2、  调整前应确认被调整的阀门上部无钳工、焊工、土建施工，旁边没有人在拆除脚手架等工作。

2. Before adjustment, it shall be confirmed that there is no fitter, welder or civil construction on the upper part of the valve to be adjusted, and no one nearby is removing the scaffold.

3、  配电箱醒目处应挂有“有电危险”等中文标牌。

3. Chinese signs such as "danger of electricity" shall be hung at the conspicuous place of the distribution box.

4、  通电前应认真核对每根连接导线，防止损坏设备。

4. Before power on, each connecting wire shall be checked carefully to prevent equipment damage.

5、  送电时，在配电箱一方的人员应通知就地人员，得到对方同意后方可送电。送完电后应及时告诉对方。

5. During power transmission, the personnel on one side of the distribution box shall notify the local personnel, and the power can be delivered only after getting the consent of the other side. Inform the other party in time after power transmission.

七、电动阀门的故障处里出现的问题可分两部分

7、 There are two parts for the problems in the failure of electric valve

1、电动门内进水；

1. 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

In the hot state, there are many over torques in the electric valve, mainly due to the thermal expansion, the valve is stuck, and the high bypass pressure regulating valve has over torques. 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, the large-scale adjustment is carried out It is allowed to open the valve manually to 90% after a while
