When the rotary fan needs to be shut down for a long time due to production and other reasons, as a blower manufacturer, we recommend that you strictly follow the following methods, especially in seasons or regions with temperature lower than 0 ℃ or high humidity, so as to properly protect the rotary fan.

一、将控制器、配电箱等电气设备，用塑胶纸或油纸包好，以防湿气、灰尘等侵入。

1、 Wrap the controller, distribution box and other electrical equipment with plastic paper or oil paper to prevent the invasion of moisture and dust.

二、在回转风机空气过滤器前放置干燥剂，半年左右须更换一次，

2、 Place desiccant in front of the air filter of rotary fan and replace it once every half a year,

三、将所有开口封闭，以防湿气、灰尘进入。

3、 Close all openings to prevent moisture and dust from entering.

四、回转风机停机前若有任何故障或问题，应先排除，以方便将来使用。

4、 If there is any fault or problem before the rotary fan is shut down, it should be eliminated first for future use.

回转风机在长时间停用后如需重新开机，则应遵循以下步骤：

If the rotary fan needs to be restarted after long-term shutdown, the following steps should be followed:

一、除去回转风机上所有的塑胶纸或油纸。

1、 Remove all plastic paper or oil paper from the rotary fan.

二、测量电动机的绝缘电阻，应在1MΩ以上。

2、 Measure the insulation resistance of the motor, which shall be more than 1m Ω.

三、其他程序请参照回转风机相应调试步骤

3、 For other procedures, please refer to the corresponding commissioning steps of rotary fan

回转风机长时间不工作就需要我们学会如何保养，这十分重要，平常只要注意回转风机的保养，就算长时间不用，也基本不会出现什么问题，那么回转风机长时间不用，出现问题该怎样解决呢，下面我来为大家详细介绍。

If the rotary fan doesn't work for a long time, we need to learn how to maintain it, which is very important. Usually, as long as we pay attention to the maintenance of the rotary fan, even if it is not used for a long time, there will be no problem. Then, if the rotary fan is not used for a long time, how to solve the problem? Let me introduce it in detail.

1、生锈卡住了

1. Rusty and stuck

如果回转风机闲置很长时间，里面和外面会生锈的，铁柱大面积脱落，叶轮会卡住的，在这种情况下，需要用汽油、柴油、稀料浸泡、冲洗就会转动，在转动的很松的情况下，开启电源可正常工作。

If the rotary fan is idle for a long time, the inside and outside will rust, the iron column will fall off in a large area, and the impeller will be stuck. In this case, it will rotate when it needs to be soaked and washed with gasoline, diesel and thinner. When the rotation is very loose, turn on the power and work normally.

2、进入异物被卡主

2. Foreign matter is jammed

长时间不用导致大颗粒进入回转风机内，阻挡部件之间的间隙，导致风机不旋转，这时候需要把异物小心的取出来，避免颗粒破碎了，并检查叶轮之间的间隙，同时检查异物落入的原因，以免再次落入异物，用手转动轻松后，开启电源可正常工作。

Long time use will cause large particles to enter the rotary fan and block the gap between components, resulting in non rotation of the fan. At this time, it is necessary to carefully take out the foreign matters to avoid particle breakage, check the gap between impellers, and check the reasons for the foreign matters to avoid falling into the foreign matters again. After easy rotation by hand, turn on the power supply to work normally.

3、部件变形

3. Component deformation

由于长时间不用，回转风机部件出现湿效反应，会引起风机的零部件变形，不过这种情况很少。

Due to long-term use, the components of the rotary fan have wet effect reaction, which will cause the deformation of the components of the fan, but this situation is rare.
