PeakVue Technology for Machinery Analysis
PeakVue technology provides earlier, more accurate indications of developing faults in rolling element bearing machines.
Traditionally, vibration data has not been routed to the control room because it required specialized training and tools to extract any information from the data.
Emerson's PeakVue technology cuts through the complexity of machinery analysis to provide a simple, reliable indication of equipment health via a single trend. PeakVue filters out traditional vibration signals to focus on impacting, a much better indicator of overall asset health on any type of rolling element bearing machine.
And now, with the introduction of PeakVue Plus, users will find it even easier to take advantage of this technology. Watch the videos below to learn more.
Let’s look at a typical process pump running between 900 and 4,000 RPM as it passes through the four stages of bearing failure. Starting with the baseline condition for a good bearing, we see a significant amount of overall vibration. However, it is important to note that the PeakVue value is at zero. This is because a good machine, properly installed and well lubricated, should not be impacting. Therefore we can state the Zero Principle – PeakVue on a good machine should be at or close to zero.
At stage 2, small pits will being to appear, and the bearing will have less than 10% of its service life remaining. Typically there is still not indication of the developing faults in the overall vibration, but PeakVue continues to climb. When it doubles to 20, there is a serious problem with the bearing.
There will be a marked incrase in the overall vibration at the point of actual failure, but too late for planning. This in in effect notification that the machine is shutting down. In contrast, PeakVue has been indicating a developing fault over the past weeks and months. Immediately prior to failure, PeakVue levels may surge rapidly to 50 g’s or higher.
