Poor bearing lubrication identified and immediately remedied

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

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. Read more

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

Variable Frequency Drive Deterioration

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

In this third case study from his book “Enhancing System Reliability Through Vibration Technology”, James Sylvester from JPS Reliability and an Reliability Training Institute Trainer, shows how analyzing vibration and thermal data can diagnose electrical drive faults. Read more

Standby Fan Motor Bearing Defect

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

In this case study from his book “Enhancing System Reliability Through Vibration Technology”, James Sylvester from JPS Reliability and an Reliability Training Institute Trainer, shows how analyzing bearing damage can lead to the root cause of the problem. Read more

Electrical Vibration Problem

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

In this first case study James shows how vibration analysis can be used to diagnose electrical vibration problems. In this case a VFD driven Motor. Over the next few weeks James is going to share a selection of interesting vibration analysis case studies. Enjoy, and please share if you found it useful – thanks. Read more
