The vibration reason and fault diagnosis of rotatory-machinery rotor

The most fault of rotator-machinery are directly correlated with rotor and its components. To large-scaly rotator-machinery, mainly from monitoring the rotor to come to find the fault, and the vibration of rotor is the most important information source, there is good corresponding relation in vibration phenomenon and its operation state, so vibration analysis is a very effective method of the fault diagnosis. the common fault of rotor is uneven, wrong, rotor bow, machinery become flexible etc. This text probes into vibration characteristic of the rotor and fault diagnosis emphatically, Combine the embodiment, put forward the suggestion, In practice, have made better result.
