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 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 the position of 7-9; the low-pressure system is adjusted to the position of 5-7).
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.
