Application of NOPD Technique to Vibration Reduction of Rotor Compressors.

Number: pap. 1104

Author(s) : HUANG B., LU Y.

Summary

Vibration of compressor shafting system can cause the uneven air gap between the stator and the rotor, which will intensify the electromagnetic vibration of the motor. Traditional damping technique is not available for vibration and noise control due to the high temperature and high pressure conditions inside the compressors. In order to reduce the vibration of the compressor’s shafting, a technique named Non-obstacle Particle Damping (NOPD) is used and some special NOPD shock absorbers are designed for shafting vibration reduction. According to the structure of an inverter compressor, 4 NOPD shock absorbers with different numbers of filled-in particles and cavity materials are made and installed to the rotors. Results of compressor vibration test show that the vibration of the compressor with NOPD shock absorbers installed is reduced apparently in contrast with the compressor without NOPD shock absorber. And the more particles are filled in, the better effect of vibration reduction is achieved.
