咱们应留意通风设备在发动时需求留意以下几个方面：
We should pay attention to the following aspects when starting the ventilation equipment:
1、发动前应将风机进口调理风门禁止关闭，防止操作过错，带负载发动。
1. Before starting, the inlet conditioning damper of the fan should be prohibited from closing to prevent operational errors and start with load.
2、电流表指示康复到空载电流后，可调理风门开度在恰当的方位。
2. After the Ammeter indicates that the no-load current is recovered, the opening of the adjustable damper is in the proper position.
3、 发动时因发动风机后迅速停机，判别风机是否有反常现象，如发现风机有反常决断停止使用，查看排除故障后方能正常发动。
3. When starting, due to the rapid shutdown of the fan after starting, determine if there is any abnormal phenomenon in the fan. If any abnormal decision is found to stop using the fan, check and eliminate the fault before starting it normally.
4、通风管道查看轴承的润滑油位是否正常、冷却水管供水状况、联轴器是否无缺、检修孔门是否关闭。
4. Check whether the lubricating oil level of the bearing is normal, the water supply condition of the cooling water pipe, the coupling is intact, and the manhole door is closed.
5 、留意发动的时刻以及空载电流是否正常。
5. Pay attention to the starting time and whether the no-load current is normal.
6、通风设备运转查看有没有反常。
6. Check if there are any abnormalities in the operation of the ventilation equipment.
7、通风管道为防止新装置置时没整理洁净风机内部的杂质，发动风机后迅速停机，判别风机是否有反常现象，如发现风机有反常决断停止使用，查看排除故障后方能正常发动
7. In order to prevent impurities from being cleaned inside the fan during the installation of the new device, the ventilation duct quickly shuts down the fan after starting it to determine if there is any abnormal phenomenon in the fan. If any abnormal decision is found, stop using the fan and check and eliminate the fault before starting it normal
