Confidently Diagnosing Misalignment With Vibration Analysis

Using brand new 3D animations, we will explore the physical motion associated with misalignment and explain why we see the characteristic vibration patterns that are common when machines are misaligned.

We will also discuss why misalignment is so often misdiagnosed. We will introduce phase analysis, and demonstrate how two channel analyzers make phase analysis very easy to perform, and how it helps us to accurately diagnose misalignment.

1) How does the vibration pattern change when machines are misaligned

2) How to accurately diagnose misalignment

3) Why phase analysis is such a useful tool

Belt Faults

Belt drives can cause many strange looking spectra. To analyze and troubleshoot belt drives it is imperative to have a high resolution analyzer. I use one with 3200 lines of FFT. To those still using 400 lines that might seem like overkill. This paper, though, will show the necessity of high resolution when troubleshooting many vibration problems.

Monitoring the Performance and Health of a Shredder Plant

In today’s difficult business conditions, it is more important than ever to know how your recycling plant is performing. It is also vital to avoid sudden expensive breakdowns, and to keep plant downtime to a minimum. This is particularly difficult in the scrap auto recycling industry, where all the machinery must be capable of handling large vehicles with a high throughput; the machinery takes a battering, and sooner or later it must be maintained or it will break down. While it is possible to build some redundancy into an operation – such as having spare scrap handling cranes – there is often only one shredding machine at the heart of an auto shredding plant. If the shredder is working well, then the plant is productive; and if the shredder is not working, then the plant is inoperative.

Azima DLI Ensures Reliability of Panama Canal Locks Using Advanced Vibration Monitoring Capabilities

Panama Canal Authority Utilizes Azima DLI’s DCX Vibration Data Collector and Diagnostic Software to Increase Uptime of Equipment Critical to Lock Movement

Azima DLI, the leader and premier provider of predictive machine condition monitoring and analysis services, today announced that its advanced vibration monitoring capabilities will be used by the Panama Canal Authority (ACP) to achieve important equipment reliability and uptime goals associated with the operation of its lock system. The ACP is the autonomous agency of the Government of Panama in charge of managing, operating and maintaining the Panama Canal.

If the Bearing is Hot: (It might be greased or not)

"Vibration analysis" is commonly used to assess bearing condition however, although the vibration data can appear ok, there are other conditions which can exist or be unknowingly created to open the door for potential failure.

I am referring to bearing lubrication. This is an area where although, information by the bucket full can be easily obtained, Practicing the art of proper bearing lubrication tends to be ignored, not practiced or severely misunderstood. Usually, one step in a PM requires maintenance personnel to grease the bearings. This practice has become acceptable because we all know what happens when there is not enough grease so...we apply the old rule of thumb that is; "better to have too much grease than not enough" right? The problem is... we really aren't sure how many times or the last time a bearing on a particular machine got greased. It has been said over and over again that over greasing can cause more damage. Unless some system has been put into place to record the greasing activity, we can never be 100% sure. I will demonstrate through the use of infrared technology what the outcome will be if over lubrication happens.

Great Savings for Great River

Continuous Monitoring Lowers Costs, Boosts Performance

by Robert Skeirik and Craig Truempi

The ability of continuous vibration monitoring to provide early detection of potential bearing problems in rotating equipment allows users to plan maintenance work in advance. This maximizes uptime by minimizing the impact of costly machine break downs.

Practical Vibration Analysis: 10 Steps to Spectrum Analysis Success

A 53 Minute iPresentation Tutorial by Jason Tranter, Mobius Institute

So much valuable information can be hidden in a vibration spectrum. This Webinar will provide you with a series of steps you can follow to ensure that you unlock that information and make an accurate and timely diagnosis.

1) Learn how to quickly assess the quality and severity of the vibration

2) Learn how to categorize the peaks in the spectrum and thus direct the analysis process

3) Learn how to identify possible bearing faults even if you don't have bearing forcing frequencies
