PeakVue Plus – Bearing Friction

In this the third of three videos on PeakVue, James Sylvester shows that when the Emerson AMS 2140 is setup correctly, PeakVue Plus can detect issues with lubrication health, in this case, the bearing friction was off the scale! The asset in question is a critical plant fan on a variable speed drive with an operational speed of 1200rpm with 22224 EK Taper roller bearings installed.

Incorrect grease used

This short presentation shows how PeakVue Plus detected incorrect grease used by the contractor prior to any considerable bearing damage occurring. As part of the site maintenance annual shutdown the bearing caps were opened, the grease removed and it repacked with fresh grease. Watch as James explains how the PeakVue Plus technology helped confirm the root cause, (6 mins):

PeakVue Introduction – Part II

In this the second of three videos on PeakVue, James Sylvester shows that when the Emerson AMS 2140 is setup correctly, PeakVue can pick up sub surface Hertzian cracks. In this example, James refers to a 110KW Motor on a variable speed drive for a plant critical pump.

Outer Race Defect Identified

On an asset assessment survey of a critical plant, a sub surface defect on a motor bearing was identified; this was very early detection and allowed time to plan in the bearing replacement as to not disrupt the production schedule. Watch James explain in layman’s terms how the PeakVue technology works and what sets it apart from the others (6 mins).

PeakVue Introduction – Part I

Here is a the first example from James Sylvester of how visually helpful the new Emerson 2140 PeakVue Plus is while working on site.

Poor bearing lubrication identified and immediately remedied

On a recent survey of a critical 110KW blower motor we noticed the PeakVue levels had increased. While at the machine we quickly ran the PeakVue plus and this highlighted the issue as a poor lubrication condition.

Instead of writing this in the report then living in hope the motor is correctly greased, we showed this at the machine to the site fitter and we were immediately permitted to lubricate the bearings and the levels reduced.

PeakVue Plus was great as we did not have to upload to the laptop to explain. We just showed them the colour chart indicating poor lubrication and they acted upon it there and then.

Flue Gas Recycle Fan: Introduction

The Flue Gas Recycle Fan is part of the COGA unit. The fan increases the efficiency of the COGA unit by recycling a proportion of the incinerated gases from the COGA stack. The fan is critical in sustaining high rates of operation on the plant, catastrophic failure of this fan would result in a COGA unit shut down. This would increase the emissions to the atmosphere and heavy fines could be imposed by the Environment Agency. Read more

Dynamic Vibration Absorber

BONUS: This is the 6th and final (free) case study in the series on Enhanced System Reliability.

In this sixth case study from his book “Enhancing System Reliability Through Vibration Technology”, James Sylvester from JPS Reliability and an Reliability Training Institute Trainer, shows how the use of Dynamic Vibration Absorbers can effectively reduce vibration levels. This case study covers a 2-year project period from initial root cause diagnosis to designing, trialing, and implementing an innovative cost-effective solution. Read more

23RPM Defect on a 4 Point Contact Bearing

This was to be the final of the five case studies on Enhanced System Reliability by James Sylvester. But, following on from feedback we will have one more case study next week, this will be an extra long project case study!

In this fifth case study from his book “Enhancing System Reliability Through Vibration Technology”, James Sylvester from JPS Reliability and an Reliability Training Institute Trainer, demonstrates vibration analysis of a slow rotational 4 Point Contact Bearing, with a 23RPM Defect. This is to remind us that correct database set up, and Time Waveform Analysis is so important in slow rotational bearings. Read more

Vibrating Screen Gearbox Bearing Defect

This is the fourth of five video case studies on Enhanced System Reliability by James Sylvester.

In this fourth case study from his book “Enhancing System Reliability Through Vibration Technology”, James Sylvester from JPS Reliability and an Reliability Training Institute Trainer, shows how it’s possible to diagnose faults on a vibrating screen. We demonstrate that by measuring the correct vibration parameters you can resolve defects in harsh applications, even an inner raceway defect on a vibrating screen. Read more

30-Second Summary

  • Understanding the machine, getting early warning of faults, detection of all fault conditions, and repeatable measurements are crucial for effective vibration analysis.
  • Vibration analyst courses that are compliant with courses that follow the ISO 18436 standard are quintessential in the present-day scenario.
  • An efficient vibration analyst must take quick and economical measurements, and aim to detect the most common faults before the failure of the machine.

ABSTRACT – Vibration Analyst Checklist

Practical advice is given on getting the most meaningful and the most accurate information from machine vibration analysis, viz. on identifying the appropriate measurement locations and axes, the optimal data collection settings and the best analysis techniques. Also stressed are the importance of good reporting practices and the desirability of root cause analysis and acceptance testing.

INTRODUCTION

Vibration analysis is a fantastic field. For the analyst it is challenging and stimulating, and it should be rewarding. For the employer, it offers great financial rewards. But the question is: are you taking full advantage of the potential of vibration analysis? On the face of it, it can seem pretty simple. If you follow the set-up recommendations of the data collector vendor, and make sure that you mount the sensor on the bearing, then you will capture a spectrum that looks about right. It will have peaks and patterns which make it look like the spectra you see in the case studies. So you must be doing it correctly, right?  Not necessarily. Read more
