高低温一体机在使用过程中，可能会因为环境、材质、不良使用习惯等出现大大小小的一些问题，今天就给大家简单讲解一些比较容易出现的问题以及解决方法，希望可以帮助到大家。

一、高低温一体机固定件引起共振原因

1. 在水泥地面安装是，可能会因为水泥的基础太轻或灌浆不良，引起风机基础与地基脱节。地脚螺栓的松动，基座连接不牢固导致基础刚度不够。

2. 风机底座或蜗壳刚度过低。

3. 与风机连接的进出口管道未加支撑和软联结。

4. 邻近设施与风机的基础过近，或其刚度过小。

解决方法:

1. 加固基础和重新灌浆，紧固螺母。

2. 加强刚度。

3. 增加制成和软连接。

4. 调成距离或坚强其刚度。

二、高低温一体机转子不平衡引起的振动原因：

1. 高低温一体机风机叶片被腐蚀或磨损严重;

2. 风机叶片总装后不运转、由于叶轮和主轴本身重量、使轴弯曲;

3. 叶轮表面不均匀的附着物，如铁锈、积灰或沥青等;

4. 运输、安装或其他原因，造成叶轮变形，引起叶轮失去平衡;

5. 叶轮上的平衡块脱落或检修后未找平衡。

解决方法：

1. 修理或更换;

2. 重新检修，总装后如长期不用应定期盘车以防止轴弯曲;

3. 清除附着物;

4. 修复叶轮，重新做动静平衡试验;

5. 高低温一体机找平衡。
