In the centrifugal fan use, bearing high temperature is a common fault, the causes of high bearing temperatures are the following: ① poor lubrication Chengde low pressure centrifugal fans, oil (fat) deterioration or lack of oil (fat); ② bearing assembly poor quality, 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 bad centrifugal fan cooling, ventilation, or lack of water, such as through: the application of centrifugal fan Popular, it is equivalent to the application in a confined space, for the confined space, the importance of centrifugal fans here? Wonderful fans think this is closely related to modern life. With highly developed Langfang FRP centrifugal fan of human civilization, into the interior of the type and quantity of chemical products and electrical equipment increased, housing construction was more confined, indoor pollution factor and increasing ventilation capacity but instead weakened, which makes some indoor outdoor pollutant concentrations up to several times more than that. Indoor air pollution is due to all causes of indoor air of harmful substances exceeding Baoding multi-stage centrifugal blower, thereby affecting the health of indoor pollution behavior. Pests include formaldehyde, benzene, ammonia, radon and the like. With the increasing pollution levels, the body will produce sub-health and even life-threatening reaction. It can be seen in much of our lives need ventilation, centrifugal fans indispensable in all fields, in the use of theater, workshop, to create a safe environment for everyone. Contribution to the industry, but also indelible, creating a wealth of commercial value, is now also launched in agriculture-related applications, has become an important supplementary food storage facilities. The diverse needs of the industry put forward to promote the innovation of fan performance, excellent technical team fans will further deepen the integration of new technologies and understanding, in order to meet all the needs of high-quality equipment.
