Many times the fan in the use of some unusual phenomenon is very common, but these anomalies often lead to the use of fan efficiency, so that the use of the fan to a certain extent, be damaged, part of the reason is the user in the choice of mistakes , Different models bring different results, if used in an inappropriate place, then the abnormal phenomenon is inevitable.
Axial fans can be produced according to different types of different types, steel fan, FRP fan, plastic fan, PP fan, PVC fan, aluminum fan, stainless steel fan, etc. These are more common in axial fans Type, different types of fans in the use of different problems, so the solution is also a big difference. The most common phenomenon of axial fans in crack or breakage occurs when the blades are cracked or broken, and are likely to occur in the delivery and induced draft fan. In recent years, there have been many cases in several large power plants. Such as rotor imbalance, rotor vibration, etc., the most serious or even impeller accident; motor failure. Such as over-current, etc., serious burned motor; oil station oil leakage, adjust the oil instability. That is, the regulation of fan performance also threatens the safety of the fan.
Blade wear is also a very typical phenomenon. Mainly occurs in the induced draft fan. As the electrical input timing is not good or electrical failure, causing the fan wear. This is the coal mine power station induced fan most prone to failure. Once the fan appears above the situation, the first power outages, check the flow fan is not long-term operation in the stall conditions, the pressure amplitude of the air pressure increased significantly, the blade resonance damage; body itself is no problem, the starting design is reasonable ; Installation of the hidden dangers, such as shaft imbalance or poor connection, resulting in fan vibration, bearings, couplings easy to damage.
If the user finds that these methods can not solve the problems caused by the fan, this time on the need to consider the type of fan, is not due to the type of failure caused by these problems, once the cause of the problem, to immediately find a solution The way to solve these problems of the fan.
