An imaging and analysis system for a component of a rotary machine includes an image capture device operable to capture image data from at least one selected type of electromagnetic radiation that is at least one of reflected from and transmitted through the component. The system also includes an image processor configured to generate processed data from the captured image data. The system further includes a control system configured to automatically identify a condition of the component by comparing the processed data to stored reference data. The reference data is stored in a format that enables direct comparison to the processed data.

Adjustment of the distance between the tip of a pickup section and the outer surface of a shaft of a rotor can be carried out easily and with high precision. In a vibrometer mounting mechanism securing a measuring section of a vibrometer for measuring vibration of a shaft of a rotary machine to a casing of the rotary machine, the vibrometer mounting mechanism includes a case secured to the casing with fixing means; an inner cylinder that accommodate the measuring section at one end, that is disposed in the inside of the case, and that slides relative to the case; and an adjustment bolt disposed at one end of the case and capable of moving forward and backward with respect to the case and the inner cylinder, wherein the inner cylinder is made to move in a direction away from the shaft by the adjustment bolt being inserted into the case and the inner cylinder, and wherein the inner cylinder is made to move in a direction toward the shaft by the adjustment bolt being retracted from the case and the inner cylinder.

A method and an apparatus are disclosed to detect faults in a rotary machine having a rotor and at least two stator windings. The method comprises generating an input signal and applying the input signal to stator windings while the rotor is locked at a rotor position, measuring output signals from the stator windings and processing all the output signals by Fourier transform to obtain frequency responses of the stator windings, forming derived quantities from all the frequency responses so that the derived quantities are independent of the rotor position, comparing the derived quantities with corresponding reference quantities, determining that there is a fault in the rotary machine if a magnitude or phase difference between the derived quantities and the corresponding reference quantities exceeds a threshold number. The apparatus is designed to test a rotary machine using the inventive method.

An autorotation machine using the theory of rotating lever comprises a main wheel, a first vice wheel, a second vice wheel, a weighted activity wheel, a gravity rotation metal belt and a dog driver. The first vice wheel is above the main wheel, while the second vice wheel and the weighted activity wheel are respectively positioned at the both sides of the main wheel. The gravity rotation metal belt, which has a bend metal belt, is fixed together with a plurality of matching blocks at one outer side of the bend metal belt. The dog driver is positioned below the weighted activity wheel used for lifting the weighted activity wheel and the gravity rotation metal belt. When the dog driver moving out of the bottom of the weighted activity wheel, the weighted activity wheel and the gravity rotation metal belt can move a scheduled distance slightly downwards and lead a kinetic energy driving the gravity rotation metal belt and then driving the second vice wheel to output power.

The invention relates to the technical field of fault diagnosis of rotating mechanical equipment, and discloses a method for drawing an axis trajectory diagram by using a variational mode decomposition reconstruction signal, which comprises the following steps: determining the number of layers of a variational mode decomposition model through an information entropy mean value of an intrinsic mode function component, and reconstructing the signal by using the magnitude of correlation to obtain an axis trajectory diagram; and finally, an axis trajectory diagram of the reconstructed signal is made. The axis trajectory diagram obtained by the method can effectively reduce the noise in the original axis trajectory diagram, and improves the accuracy of subsequent fault diagnosis.
