How to prevent the sandblasting tube from resonance :
The aesthetics of some companies' future products will buy sand blasting machines that match their own needs. Sand blasting pipes are very important compared to sand blasting machines. After installation, resonance should be avoided during use. Generally it is divided into two forms: axial vibration and torsional vibration.
1. Axial vibration is caused by the axial movement of the shaft.
2. Torsional vibration is usually caused by the friction between friction pairs.
After installation of the blast pipe , the torsional vibration may be converted into axial vibration by itself. Because in many cases, when welding makes the frequency of the periodic expansion and contraction of the sandblasting tube equal to the natural frequency of the sealing device, resonance may occur, resulting in greater stress and fracture.
So, how to prevent the sandblasting tube from resonating?
You can change the thickness, number of sheets, spacing, material, and installation length of the sand blasting pipe so that the natural frequency of the seal should be designed to be greater than the main vibration frequency. In addition, a damping plate can be installed around the bellows to produce slight elasticity Load to ensure contact with the sand blasting pipe, and the kinetic energy of the bellows is derived through the vibration damping sheet to prevent resonance.
