The use of analytical instruments to diagnose the equipment in time is one of the most common methods to ensure the stable operation and troubleshooting of large units. Daqing Petrochemical Plant, an air compressor plant in an air separation plant after the overhaul of the air compressor in July 1998, during the boot process, the speed after the critical speed exceeds a certain value, the value of the air compressor side of the rapid increase in vibration and Exceed the value of the jump and interlocking jump car (this process too
