忽然断电这种状况在风扇行业很常见，在电力紧张的地区呈现更频频的断电现象，假如咱们的罗茨鼓风机遇到断电现象，咱们该如何操作？

Sudden power failure is very common in the fan industry. Power failure occurs more frequently in areas with power shortage. If our roots blower encounters power failure, how should we operate?

咱们需把罗茨鼓风机的电源闸断开，避免忽然打电话，把风机打坏，后面给大家讲解具体原因。

We need to turn off the power switch of Roots blower to avoid making a sudden call and breaking the blower. We will explain the specific reasons later.

翻开排气阀，避免其他问题。

Open the exhaust valve to avoid other problems.

查看线路，扫除线路毛病，罗茨鼓风机忽然停机，忽然断电，形成这种状况的原因很多，咱们需求进一步查看，然后扫除毛病。

Check the line and eliminate the line faults. The roots blower suddenly stops and suddenly loses power. There are many reasons for this situation. We need to further check and eliminate the faults.

前面说过，为什么罗茨鼓风机怕忽然打电话？假如开关翻开，忽然打电话，很可能无法发动，因为罗茨鼓风机发动时，需求先翻开排气阀，然后渐渐封闭排气阀，风机逐步升压，封闭排气阀。罗茨鼓风机安装的附件:止回阀。一旦罗茨鼓风机断电，没有止回阀，罗茨鼓风机的叶轮就会直接损坏。咱们也多次遇到这样的事故，有的叶轮严峻损坏，有的异常噪音成长。

As I said earlier, why is roots afraid to call suddenly? If you open the switch and call suddenly, you may not be able to start it, because when the roots blower starts, you need to open the exhaust valve first, and then gradually close the exhaust valve. The fan will gradually boost the pressure and close the exhaust valve. Accessories for Roots blower installation: check valve. Once the roots blower is powered off and there is no check valve, the impeller of the roots blower will be directly damaged. We have also encountered such accidents many times. Some impellers are severely damaged and some have abnormal noise growth.

罗茨鼓风机断电，弄清楚，是全厂停电，仍是线路老化等原因，假如是线路毛病，断开总闸查看线路，把问题弄清楚，把存在的问题和毛病扫除洁净，然后再翻开电源。

The roots blower is powered off. Find out whether it is the power failure of the whole plant or the aging of the line. If it is a line fault, disconnect the main gate to check the line, find out the problem, clean up the existing problems and faults, and then turn on the power supply.
