The Vibration Analysis Of Turbocompressor

In recent years, the vibration problem of turbocompressor is more and more being concerned by people in application. The function of the main parts, the movement principle and the process of research are discussed in this paper. At the same time, the performance of the compressor and the performance curve are introduced. Combined with experience, the causes of vibration are analyzed in theory through the curve. Combined with the real malfunction of seven compressors, the vibration curve and the frequency chart are measured through special tool. Exceptionally, the undee picture of vibration and the performance of frequency chart are synthetically analyzed in this thesis. Based on the vibration phenomenon, the malfunction of the asymmetry of the rotor, the imbalance of the rotor, the surge of the oil film and the friction between the rotor and the air are deeply discussed and the causes of the vibration and mechanism character are mastered. Finally, we take a lot of measure in order to improve the vibration of the compressor according to the theory and reach satisfied effect in application. The influence factors of the vibration of the compressor are more through research. For example, the same vibration phenomenon may arise from many causes and may result from many factors together. Therefore many measures should be taken and be analyzed synthetically in the judgement of the causes of the vibration. In order to improve the stabilization of the compressor movement, a few advice are given with accessorial equipment and pipe design.
