Analysis of the causes of HVLS Fans bolts

Some connecting parts of HVLS Fans need to be connected with bolts. Safety accidents caused by loose bolts of HVLS Fans often occur in the market. From a professional point of view, the loosening of bolts is called the "attenuation" of the bolt. The essence of a threaded connection is to hold the connecting parts together through clamping force, so the essence of "attenuation" is the reduction of the clamping force after tightening. , we can divide the reduction of clamping force into two parts: relaxation and loosening.

Relaxation: Relaxation means that over time, the clamping force of the bolts used to connect parts decreases compared to the clamping force when tightened, but the bolt or nut does not rotate.
Looseness: Looseness means that the clamping force is reduced, causing the bolt or nut to rotate in the loosening direction, thereby further reducing the clamping force. In this case, the bolt or nut may become completely loose, which must be avoided in connections involving personal safety.
Bolts play a very important role in the entire HVLS Fans. The effective control of bolt torque is directly related to the reliability, safety and sealing of the product. Only when all indicators can be guaranteed can product quality be better guaranteed. In order to avoid loosening and loosening of bolts, it is very important to correctly select and use tightening tools. If attenuation parts are found, bolts should be repaired and replaced in time.
