Analysis and Diagnostic System  infiSYS RV-200

Product Overview

A vibration analysis & diagnostic system that fits various rotating machinery and supports safe operation and improved operational efficiency

infiSYS RV-200 is a vibration analysis & diagnostic system that analyzes data for its phase mark and frequency and then plots analysis graphs required for vibration analysis.

Advantages

  • By optimizing plant operation, it supports customer’s productivity and reliability.
  • Detects abnormal symptoms from vibration characteristics or subtle change in vibration. Reduces risks of unplanned production shutdown by taking proactive approach.
  • Advanced diagnostics realizes assumption of causes and areas of anomalies and detailed analysis. Help users practice optimum, efficient maintenance.


Features

· For all rotating machinery
Applicable to all scales from small rotating machinery supported by rolling element bearings to large rotating machinery supported by journal bearings.
· High-speed and flexible system configuration
While achieving high-speed data acquisition, the system can be configured with various monitors, including non-SHINKAWA monitors.
· Sophisticated data analysis and various graphs
The software provides a variety of analytical graphs which are optimized for the type of machinery and condition, satisfying stringent demands of vibration analysts and other plant personnel.
· User-friendly operability and plotting functions
Intuitive software interaction with drag and drop graph display manipulation, graph area switching tab, etc.

System Configuration

· Basic System
When used for large rotating machinery, it acquires phase mark signals and shaft vibration waveform, processes phase analysis and frequency analysis, and then displays the information in various graphs for further analysis. For small rotating machinery, infiSYS acquires acceleration vibration waveform of casing and the information is displayed with graphs based on the frequency analysis.

· Configuration Example for Large Rotating Machinery
Based on the vibration waveform detected by shaft vibration sensors, the system provides vibration monitoring and anomaly analysis for rated-speed operation, and shaft behavior analysis for critical startup/shutdown.

· Configuration Example for Small Rotating Machinery
Based on the vibration detected by acceleration sensors installed on the bearing housings, the system provides trend management and abnormality diagnostics not only on overall vibration but also on vibration of each fault frequency resulting from bearing failure.

Applications

Steam turbines, Gas turbines, Hydro turbines Electric generators, Feed pumps, Fans, Blowers, Compressors, BOP machinery, Rotating equipment critical to your facility

Data Display Examples

· Polar Plot
This shows the vibration vector at the time of critical startup/shutdown of the machine. From this plot, the user can observe the balancing condition, vibration levels and critical speed during the startup/shutdown of the machine.
Displayed data (Switchable display): 1X, 2X
This allows over lay of current data on top of past data.
· Waterfall Plot
This plot is used to analyze changes in frequency components that occur over time.
Cascade plot can also be displayed with width (z-axis) as rotation speed to analyze changes in frequency components in relation to changes in rotation speed.
· Trend Plot
This plot displays short term and long term chronological changes using a line chart.
Displayed data (multiple selections are allowed): Rotation speed, GAP, OA, 0.5X amplitude, 0.5X phase, 1X amplitude, 1X phase, 2X amplitude, 2X phase, Not-1X amplitude, nX1 to nX4 amplitude and phase, Smax amplitude, various alarm setting values.
· Machine Train Diagram
The 3D illustration of rotating machinery diagram displays the rotation speed as well as the location and the vibration amplitude of each measuring point.
For each machine, current values can be displayed in a list view.
· Orbit and Waveform Plot
This plot composes signals from each X and Y sensor and displays the dynamic motion of the center of a rotating shaft.
The Orbit plot helps to identify any abnormal status including imbalance, misalignment, oil whirl and oil whip.
· Bode Plot
This plot displays the amplitude and phase in separate graphs with rotation speed used as the horizontal axis.
From this plot, the user can see the vibration status and critical speed during the startup/shutdown of the machine.
Displayed data (Switchable display): 1X, 2X
This allows over lay of current data on top of past data.

Case Studies

· Unbalanced Vibration
The most common abnormal vibration is due to the mismatch between shaft center and mass center, due to manufacturing error or machine components missing.
The characteristic of the vibration generates the rotation synchronous component (1X), which is sine wave or similar. Vibration becomes largest at critical speed.

  • S-V Plot

  • Spectrum Plot
· Oil Whirl Vibration
Self-excited, unstable vibration typical for sleeve bearing supported rotating machinery. Possible causes include effects from the shape of the sleeve bearing, oil film characteristics, etc. Normally, this vibration appears at two or less times lower the critical speed, and the frequency is around half the rotation synchronous frequency (0.5X).

  • S-V Plot

  • Spectrum Plot
· Misalignment Vibration
Vibration that occurs when the shaft centers of driving rotating machinery and its associated driven rotating machinery are not properly aligned. Typically the vibration includes rotation synchronous frequency component (1X) and harmonic components (2X, 3X).

· Loss of Rotor Component
When a piece of rotor component is lost/flies off, unbalanced vibration condition suddenly changes. The typical phenomenon includes sudden changes in the amplitude and phase angle (vibration vector) of the rotation synchronous frequency component (1X).

User-friendly Operability

infiSYS RV-200 (hardware & software) has a simple user interface, that is easy and instinctively operated by most plant personnel.
Quick learning of graphic display.

· Drag & Drop
From tree at left to display area at right, desired plots can be displayed anywhere you want.
· Tile Display
Instant pickup of desired channel plot from tile display window. Channel plot specific window opens with one click.
· Page Switching Tab
Desired graph display page can be displayed simply by switching the tabs. A step to create a new page is also simple. (Up to 20 pages.)
