消防排烟风机的轴承常见的故障就是温度升温太快，对于这一点，我们了解到，轴承内部间隙太小或机件设计制造精度不佳，这都是分机轴承运转温度偏高的主因。所以通常情况下，我们为方便消防排烟风机设备的安装、拆修和维护，我们会建议在设计上多采用紧定套轴承锥孔内环配合之轴承座轴承，然而也易因安装程序上的疏忽而发生问题。除了以上要点之外，我们还要特别了解到的一点就是要做好适当间隙的凋整。其中轴承内部间隙太小，运转温度急速升高；而对于轴承内环锥孔与紧定套配合太松的话，轴承易因配合面发生松动而于短期内故障烧损。
The common fault of the bearing of the fire smoke exhaust fan is that the temperature rises too fast. For this, we know that the main reason for the high operating temperature of the bearing of the unit is that the internal clearance of the bearing is too small or the design and manufacturing accuracy of the parts is not good. So usually, in order to facilitate the installation, disassembly and maintenance of the fire smoke exhaust fan, we will recommend that the bearing seat bearing with the inner ring of the tapered hole of the bearing with the fixed sleeve should be used in the design, but it is easy to cause problems due to the negligence in the installation procedure. In addition to the above points, we also need to know that we need to do a good job in the proper clearance of the withering. The internal clearance of the bearing is too small, and the operating temperature rises rapidly. However, if the fit between the taper hole of the bearing inner ring and the tightening sleeve is too loose, the bearing is easy to burn due to the loose fit surface in a short time.
