摘要
涡轮增压器转子正常工作时转速可达十几万转,由于经常发生转子碰磨故障,危害严重。针对这一问题,对该转子进行了振动测试,并对测量信号应用HP3567A进行了频谱分析。确定了该转子正常运转时的振动特点,找出其发生碰磨故障的主要原因,为产品的排故、改造提供了依据。
The rotating speed of a light rotor in a type of supercharger often reaches 90000 r/min or more. During experiments and employment of the supercharger, rubbing faults may arise, such as the journal rubs against the bearing surface and the rotating blade rubs against the stator. These faults are usually very dangerous and often make the whole system lose efficiency. In order to find the reasons, the vibration signals of the rotor bearing were recorded and analyzed by signal analysis apparatus-HP3567A. According to the spectrums of the signals, rotor vibration features were examined and the reasons that cause the rubbing faults were found.
