Taiwan fan brand analysis of small stainless steel fan failure.Heater Fan Processor

　　There are different types of fans, and one of the more common ones is small stainless steel fans. Small stainless steel fans offer a range of advantages, such as small footprint and corrosion resistance. However, small stainless steel fans sometimes fail during use. So what is the cause of the failure of small stainless steel fans? What are the solutions? The following is the analysis of Taiwan fan brands.

　　The reason for the failure of the centrifugal fan

　　In the normal operation of the centrifugal fan, various faults may occur. For the faults that occur, the Wenzhou boiler fan must promptly identify the cause and deal with it to prevent the occurrence of accidents. Vigorous movement of the bearing housing can be caused by the following reasons:

　　1. The fan shaft is not parallel to the motor shaft, and the pulley groove is dislocated.

　　2. The casing or air inlet rubs against the impeller.

　　3. The stiffness of the foundation is not good or not strong.

　　4. The impeller rivets are loose or the disc is deformed.

　　5. The impeller shaft disc and shaft are loose.

　　6. The connection bolts between the casing and the bracket, the bearing box and the bracket, the bearing box cover and the seat are loose.

　　7. The installation of the fan inlet and outlet pipes is not good.

　　8. The rotor is unbalanced.

　　Analysis of the unstable wind speed of centrifugal fans

　　When studying the speed of a centrifugal fan, it can usually be regarded as a DC speed-regulated motor, a small boiler fan, and its speed is mainly changed by an adjustable resistor. Just put the controllable rectification effect on both ends of the motor, which can control the speed of the centrifugal fan, but if the speed is unstable, what is the reason?

　　On the one hand, it may be because there are some problems in the four rectifier diodes of the centrifugal fan and the foreign boiler fan, which affects the effect of the entire equipment.

　　On the other hand, maybe the carbon powder or carbon brushes of the motor rotor and commutator are not even. At this time, you can first take a look at the adjustable resistance of the fan. It is good if the resistance value changes with the adjustment.

　　On the other hand, the problem may lie in the thyristor, such as open circuit, poor contact, short circuit, inability to touch, etc. are the reasons for the unstable speed. In addition, if the adjustable resistor has poor contact, the stability of the speed will also be disturbed.

　　In the normal operation of the centrifugal fan, various faults may occur. For the faults that occur, the Wenzhou boiler fan must promptly identify the cause and deal with it to prevent the occurrence of accidents.

　　To sum up, Taiwan fan brands tell us that the failure of small stainless steel fans is not terrible. As long as we conduct investigation and analysis on the basis of being familiar with the structure and operation mechanism of small stainless steel fans, we can find the reasons for the failure of small stainless steel fans. Thereby processing, so that the small stainless steel fan can resume normal operation.
