Abstract

The invention discloses a fault diagnosing device and diagnosing method of a high-speed rotation device. The fault diagnosing device is characterized by comprising a rail base, a rail, the high-speed rotation device and fault diagnosing equipment. The fault diagnosing method of the high-speed rotation device comprises the following steps of: at first, defining a fault mode and collecting a feature set F{.} of the high-speed rotation device in the corresponding fault mode; and judging the follow-up real-time collected feature set F{.} of the high-speed rotation device through a special algorithm, so that the corresponding fault type is judged. Compared with the periodical detection and maintenance and the post-accident maintenance, the movement state of the high-speed rotation device can be monitored in real time; the faults are classified and early warned; and the damage of entire mechanical equipment, caused by the fault of the high-speed rotation device, can be avoided.

Description

technical field [0001] The invention relates to a high-speed rotating device fault diagnosis device and a diagnosis method thereof. Background technique [0002] With the rapid development of science and technology, the application of high-speed rotating devices in mechanical equipment is more extensive. The use of high-speed rotating devices not only improves the efficiency of machine operation, but also makes machine manufacturing develop in the direction of high automation such as complexity and integration. However, the integration of a large number of high-speed rotating devices also makes the mechanical structure equipment increasingly complex. Therefore, in mechanical equipment, real-time monitoring of the operating status of high-speed rotating devices is an important guarantee for maintaining the overall good operating status of mechanical equipment. Among them, in the monitoring process, the classification and diagnosis of fault types in the motion state of high-s...
