Abstract

A method of analyzing a structural condition of a machine is described. The method includes determining a position of a portion of a machine, a rotating shaft, a fluid transfer system, or a reciprocating machine in operation; collecting an image of the portion with an image collector; synchronizing the determined position of the portion with the collected image of the portion; amplifying the synchronized image; and storing the amplified image to a memory. Related apparatuses, systems, storage media, techniques and articles are also described.

First claim

What is claimed is:

1. A method, comprising:
determining a position of at least one portion of a machine in motion or a fluid transfer system in operation by a position sensor;
collecting images of the at least one portion of the machine or the fluid transfer system with an image collector, wherein an image capture rate of the image collector is selected based upon the determined position;
synchronizing the determined position of the at least one portion of the machine or the fluid transfer system with at least a selected one of the images of the at least one portion of the machine or the fluid transfer system;
amplifying at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system; and
providing the amplified at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system.

2. The method of claim 1 , wherein an image capture rate of the image collector is a number of the images of the at least one portion of the machine per revolution or reciprocation of the machine or a number of the images corresponding with a repeating cycle of a pumping system of the fluid transfer system, and wherein the image capture rate of the image collector is not a number of frames per unit of time.

3. The method of claim 1 , wherein the amplifying includes amplifying display of motion across a distance greater than about 0.1 μm and less than about 100 μm.

4. The method of claim 1 , wherein, in the collecting images of the at least one portion of the machine or the fluid transfer system with an image collector, for at least one image, a signal to store the image is sent in response to a specified position of the machine, the fluid transfer system, or a pumping system of the fluid transfer system.

5. The method of claim 1 , further comprising:
outputting a video including the amplified at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system, wherein the video includes an indicator of the position for one or more frames; and/or
detecting a structural condition based on the amplified at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system, wherein the structural condition is a vibration condition, and wherein the vibration condition is a lateral mode shape, torsional vibration, or torsional deflection.

6. The method of claim 1 , further comprising:
transmitting instructions to a motive power supply of the machine or a pumping system for moving fluid through the fluid transfer system to actuate the machine or the pumping system;
detecting a structural condition or a vibration condition of the machine or the fluid transfer system based on the amplified at least one of the collected images and/or the selected one of the images of the machine or the fluid transfer system;
determining whether a predetermined threshold deviates from a predetermined standard indicative of a normal operation of the machine or the fluid transfer system; and
signaling an operation status of the machine or the fluid transfer system, and/or changing the instructions to the motive power supply of the machine or the pumping system based on the determining whether the predetermined threshold deviates from the predetermined standard indicative of the normal operation of the machine so as to indicate an aberrant operating condition of the machine or the fluid transfer system; and/or to mitigate the aberrant operating condition.

7. The method of claim 6 , further comprising changing the instructions to the motive power supply of the machine or the pumping system based on the determining whether the predetermined threshold deviates from the predetermined standard indicative of the normal operation of the machine to mitigate the aberrant operating condition.

8. A system, comprising:
at least one processor; and
a memory storing at least one program for execution by the at least one processor, the at least one program including instructions, which when executed by the at least one processor cause the at least one processor to perform operations comprising:
determining a position of at least one portion of a machine in motion or a fluid transfer system in operation based upon a signal provided by a position sensor;
collecting images of the at least one portion of the machine or the fluid transfer system with an image collector, wherein an image capture rate of the image collector is selected based the signal provided by the position sensor;
synchronizing the determined position of the at least one portion of the machine or the fluid transfer system with at least a selected one of the images of the at least one portion of the machine or the fluid transfer system;
amplifying at least one of the collected images and/or the selected one of the images of the at least one portion of the machine for the fluid transfer system; and
providing the amplified at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system.

9. The system of claim 8 , the system further comprising:
the machine;
a motive power supply configured to actuate the machine; and
the image collector configured to collect images of the machine.

10. The system of claim 8 , wherein an image capture rate of the image collector is a number of the images of the at least one portion of the machine per revolution or reciprocation of the machine or a number of the images corresponding with a repeating cycle of a pumping system of the fluid transfer system, and wherein the image capture rate of the image collector is not a number of frames per unit of time.

11. The system of claim 8 , wherein the amplifying includes amplifying display of motion across a distance greater than about 0.1 μm and less than about 100 μm.

12. The system of claim 8 , wherein, in the collecting images of the at least one portion of the machine or the fluid transfer system with an image collector, for at least one image, a signal to store the image is sent in response to a specified position of the machine, the fluid transfer system, or a pumping system of the fluid transfer system.

13. The system of claim 8 , the operations further comprising:
outputting a video including the amplified at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system, wherein the video includes an indicator of the position for one or more frames; and/or
detecting a structural condition based on the amplified at least one of the collected images and/or the selected one of the images of the at least one portion of the machine or the fluid transfer system, wherein the structural condition is a vibration condition, and wherein the vibration condition is a lateral mode shape, torsional vibration, or torsional deflection.

14. The system of claim 8 , the operations further comprising:
transmitting instructions to a motive power supply of the machine or a pumping system for moving fluid through the fluid transfer system to actuate the machine or the pumping system;
detecting a structural condition or a vibration condition of the machine or the fluid transfer system based on the amplified at least one of the collected images and/or the selected one of the images of the machine or the fluid transfer system;
determining whether a predetermined threshold deviates from a prede
