消防高温排烟风机故障排除的方法：
Troubleshooting methods for fire high temperature smoke exhaust fan:
一、在处理消防风机的时候，先要把紧定套退下，之后重新调整整轴和内环的配合紧度，在更换轴承之后，其间隙要在0.10毫米。安装整理好消防风机，并重新的启动，轴承振动值及运转温度都恢复正常。二、如果消防高温排烟风机的轴承内部间隙太小或者是机件的设计制造精度不好，则是分机轴承运转温度偏高的主要原因。同时为了能方便消防风机的安装，一般在设计上面多采用紧定套轴承锥孔内环配合之轴承座轴承，但是由于容易安装就会出现疏忽而发生问题。三、如果消防高温排烟风机的轴承内部间隙太小运转温度急速升高：轴承内环锥孔与紧定套配合太松，轴承易因配合面发生松动而于短期内故障烧损。
1、 When dealing with the fire fan, the tightening sleeve shall be removed first, and then the fit tightness of the adjusting shaft and the inner ring shall be readjusted. After the bearing is replaced, the clearance shall be 0.10 mm. Install and arrange the fire fan, restart it, and restore the bearing vibration value and operating temperature to normal. 2、 If the bearing internal clearance of the high temperature smoke exhaust fan is too small or the design and manufacturing accuracy of the components is not good, it is the main reason for the high operating temperature of the bearing of the unit. At the same time, in order to facilitate the installation of the fire fan, the bearing pedestal bearing with the inner ring of the tapered hole of the fixed sleeve bearing is usually used in the design, but the problem will occur due to the negligence of the installation. 3、 If the internal clearance of the bearing of the high-temperature smoke exhaust fan is too small, the operating temperature will rise rapidly: the fit between the cone hole of the bearing and the tightening sleeve is too loose, and the bearing is easy to burn due to the loose fitting surface in a short time.
