Moving-weight, dynamic balancing apparatus for a rotary machine, in particular for industrial fans

A moving-weight, dynamic balancing apparatus for a rotary machine, in particular an industrial fan, having a rotary shaft, and at least one rotor carried by the rotary shaft and provided with main rotor bearings to allow rotary movement thereof. The balancing apparatus includes at least one moving-weight balancing unit is carried by the rotary shaft, and at least one monitoring and correcting system having a drive assembly. The at least one monitoring and correcting system monitors and corrects the unbalanced state of the rotor, and acts continuously on the at least one moving-weight balancing unit when the rotor is rotating to monitor and correct for rotor unbalance. The at least one moving-weight balancing unit has at least two balancing masses mounted to be movable under drive from the drive assembly controlled by the monitoring and correction system. The at least one moving-weight balancing unit is situated axially at a distance from the rotor to be balanced beyond the main rotor bearings, and includes a ring and at least one guide assembly. The at least two balancing masses include respective carriages that are moveable in the ring, guided by the at least one guide assembly, independently of each other along trajectories that form closed circuits around the rotary shaft under drive from the drive assembly associated with each of said at least two balancing masses.

Online state monitoring and fault diagnosis device and method for rotary machine

The invention relates to an online state monitoring and fault diagnosis device and an online state monitoring and fault diagnosis method for a rotary machine. The device comprises a data acquisition device 101, a feature extraction device 102, a data management device 103, a display device 106, a device 107 such as a mouse, a keyboard or the like for setting parameters and managing equipment by a user, a multi-model detector training device 104, and a multi-model fault diagnosis device 105. The method comprises the following steps of: acquiring signals by using the data acquisition device; storing the signals, and extracting features of the signals by using the standard feature array extraction device; training a detector by using the training device for the detector for identification; performing identification by adopting the trained hybrid model detector; and outputting and recording the identification result. The device and the method can diagnose common rotary machine faults such as shaft eccentricity, bearing eccentricity, rolling body abrasion and the like, and have the advantages of high automation degree, capability of identifying multiple fault types, capability of realizing early diagnosis, good fault database expansibility and the like.
