The boiler fan bearing the cause of the high - temperature bearing knowledge

Boiler fan running, because of the blower in acoustic laboratory to produce negative pressure, a large number of outdoor fresh air into the acoustic chamber automatically, and induced draft fan motor heat exchange in the first place, cooling, indoor temperature 50 ℃ or so. So, what is the cause of the fan bearing temperature is too high? The cantonese association fan manufacturer small make up to you in detail: 1, boiler fan bearing temperature rise too high, is likely to be caused by body violent vibration. Boiler fan bearing tilt of package, bearing in the bearing in tilt state package, lead to the fan bearing high temperature at runtime. The reasons are the fan installation and maintenance quality is not high, bearing on the edge of the allowed to adjust Angle of critical operation. 2, when the lubricant quality bad, bad, or containing impurities such as dust, sand, dirt or filling quantity or inadequate bearing box cover, seat of the connecting bolt force is too large or too small, also can cause this problem; 3, boiler fan bearing grease package not stipulated in the standard to join. Generally is post personnel to worry about lack of oil bearing burnt, fan pump the gas to join quantity too much, then phenomenon of temperature rising continuously, after reach a certain point, Generally in higher than the normal operating temperature around 10 ~ 15 ℃) Will remain unchanged, and then gradually decline. 4, the boiler fan bearing abnormal, resulting in bearing heating. Askew, before and after the installation of two axis with rolling bearings bearing different heart, fan damage or shaft bending, rolling bearing is one of the factors that affect the fan bearing temperature.
