In the centrifugal fan use, bearing high temperature is a common fault, the causes of high bearing temperatures are the following: ① poor lubrication, oil (fat) deterioration or lack of oil (fat); ② bearing assembly quality centrifugal adverse Liangshan Fans structure, preload is too large, resulting in the work space and small; ③ poor quality of the bearing itself, such as the original clearance does not comply, or roller or rings have defects; ④ fan bearing vibration withstand shock loads, etc; ⑤ bearing cooling bad, inadequate ventilation or by water, such as: centrifugal fan suspended in two cases, one using a short pause, the second is a long time suspended, regardless of for a long time or a short time, they have to remind wonderful fans We prevent the cracking problem. Stop using centrifugal blower fan, when the ambient temperature is below 5 ℃ Neijiang small centrifugal fan, equipment and piping should be let go over the water to avoid freezing equipment and piping. This winter the water pipe with the cracking problem we encounter is a reason, because if not treated residual moisture and cause failure, it was too careless, and this problem can be avoided to happen. In addition, if it is suspended for a long time, but also how to handle it? (1) the surface of the bearing and the other major components of coated anti-rust oil to prevent rust. (2) the fan rotor about every half should manually move the rotor half turn (both 180 °), before moving to be tagged parameters Luzhou centrifugal fan shaft, so that the original point of the top, moving rotor After located at the bottom. Of course, more than just a means of ensuring the maintenance of means of centrifugal fan suspended during reasonable storage, if you want to back into use, or have to do a simple check to see the status of a centrifugal fan, there is no where to go wrong, confirmation then put into use.
