Abstract

A vibration data collection and rotating machinery fault diagnostic instrument includes a machine setup engine, a measurement engine, a diagnostic engine, a measurement user interface module, a machine setup user interface module, and a diagnostic user interface module. The machine setup engine requests and receives parameters about the machinery through the machine setup user interface module. The measurement engine requests and receives sensor placement locations through the measurement user interface module and keeps track of locations that have been measured and locations that still need to be measured. The diagnostic engine diagnoses machinery faults and presents the information to the user through the diagnostic user interface module using an intuitive graphical severity scale.

Claims

1. An instrument for measuring vibrations and diagnosing a rotating machinery fault, comprising:

a user interface configured to graphically show at least one of;

(1) a sensor placement and orientation relative to a machine, wherein the sensor placement and orientation are provided by a user;

(2) one or more locations on the machine identified by the user where measurements with the sensor have been taken, and (3) one or more locations on the machine identified by the user where measurements with the sensor still need to be taken; and

an engine coupled to the user interface and configured to;

receive data from a vibration sensor; and

diagnose the machinery fault based on parameters about the machine provided by the user and the received data, rather than based on previously taken vibration data.

2. The instrument of claim 1, wherein the engine is further configured to apply a rule set to the received data to diagnose the machinery fault.

3. The instrument of claim 1, wherein the engine is further configured to determine a severity of the machinery fault based on the parameters and the received data, rather than based on previously taken vibration data.

4. The instrument of claim 3, wherein the engine is further configured to apply a rule set to the received data to determine the severity of the machinery fault.

5. The instrument of claim 1, wherein the engine is further configured to measure shaft speed directly from a tachometer coupled to the machine, wherein the diagnosis is further based on the shaft speed.

6. The instrument of claim 1, wherein the user interface is further configured to show a severity scale and a severity indicator located on the severity scale that indicates a level of severity for the machinery fault.

7. The instrument of claim 6, wherein the user interface is further configured to provide a textual explanation of the level of severity.

8. The instrument of claim 6, wherein the severity scale is a continuous scale divided into a plurality of severity categories, and each severity category is color-coded.

9. The instrument of claim 8, wherein a green color-code on the severity scale indicates a slight problem, a yellow color-code on the severity scale indicates a moderate problem, an orange color-code on the severity scale indicates a serious problem, and a red color-code on the severity scale indicates an extreme problem.

10. The instrument of claim 9, wherein the slight problem means no maintenance action is recommended, the machinery should be retested, and the condition of the machinery be monitored after routine maintenance;

the moderate problem means maintenance action is recommended to be undertaken up to months, or even up to a year, later, a frequency of measurements should be increased, and the condition of the machine should be monitored;

the serious problem means maintenance action is recommended within the next few weeks, and maintenance action should be performed during the next planned downtime or maintenance period; and

the extreme problem means immediate maintenance action is required, the machinery should be shut down, and repair action should be undertaken immediately to avoid system failure.

11. A method of diagnosing a fault of a rotating machine, comprising:

receiving, by a diagnostic instrument, parameters about components of the rotating machine;

receiving, by the diagnostic instrument, a selected vibration measurement location;

taking vibration measurements with the sensor at the selected vibration measurement location;

diagnosing, by the diagnostic instrument, the fault of the rotating machine based on the vibration measurements taken with the sensor and the parameters rather than based on previously taken vibration measurements;

determining, by the diagnostic instrument, a severity of the fault; and

displaying, by the diagnostic instrument, the severity of the fault on a displayed severity scale, wherein the displayed severity scale includes a severity indicator located on the severity scale that indicates a level of severity for the diagnosed fault.

12. The method of claim 11, further comprising displaying a textual explanation of the level of severity.

13. The method of claim 11, wherein the displayed severity level scale is a continuous scale divided into a plurality of severity level categories, and each severity category is color-coded.

14. The method of claim 13, wherein a green color-code on the severity scale indicates a slight problem, a yellow color-code on the severity scale indicates a moderate problem, an orange color-code on the severity scale indicates a serious problem, and a red color-code on the severity scale indicates an extreme problem.

15. The method of claim 14, wherein the slight problem means no maintenance action is recommended, the machinery should be retested, and the condition of the machinery should be monitored after routine maintenance;

the moderate problem means maintenance action is recommended to be undertaken up to months, or even up to a year, later, a frequency of measurements should be increased, and the condition of the machine should be monitored;

the serious problem means maintenance action is recommended within the next few weeks, and maintenance action should be performed during the next planned downtime or maintenance period; and

the extreme problem means immediate maintenance action is required, the machinery should be shut down, and repair action should be undertaken immediately to avoid system failure.

16. A method for measuring vibrations and diagnosing a rotating machinery fault, comprising:

graphically showing, by an instrument, at least one of;

(1) a sensor placement and orientation relative to a machine, wherein the sensor placement and orientation are provided by a user;

(2) one or more locations on the machine identified by the user where measurements with the sensor have been taken, and (3) one or more locations on the machine identified by the user where measurements with the sensor still need to be taken;

receiving, by the instrument, data from a vibration sensor; and

diagnosing, by the instrument, the machinery fault based on the parameters about the machine provided by the user and the received data, rather than based on previously taken vibration data.

17. The method of claim 16, further comprising determining, by the instrument, a severity of the machinery fault based on the parameters and the data, rather than based on previously taken vibration data.

18. The method of claim 17, further comprising applying, by the instrument, a rule set to the received data to diagnose the machinery fault and determine the severity of the machinery fault.

19. The method of claim 17, further comprising displaying, by the instrument, a severity scale and a severity indicator located on the severity scale that indicates a level of the determined severity for the machinery fault.

20. The method of claim 19, wherein the severity scale is a continuous scale divided into a plurality of severity categories, and each severity category is color-coded.
