Infrared Thermography and Distribution System Maintenance

A vibration test and analysis guide is a simple book or electronic document that contains a variety of information about the machine. Information should include: A simple schematic of the machine with test points identified, instructions for testing the machine (especially if loads and speeds must be manipulated or verified), name plate information and a simple schematic of internal components. This information is invaluable for conducting a proper diagnosis of the machine.

When it comes to sheaves, proper vibration analysis is critical for identifying faults and preventing costly damage to equipment. These vibration analysis tips highlight two common sheave-related issues—eccentricity and misalignment—and presents practical advice for diagnosing them.

These systems combine the latest in GigE technology, digital video developments, efficient lighting and an intuitive, feature-rich user interface. The goal: keep that product moving!

An important component of Borealis' strategy is that rather than using separate condition monitoring software for their online systems, they transmit the condition data from these systems to their DCS, allowing operators to see both asset condition information and process information within a single HMI (Human Machine Interface) environment. This eliminates the need for operators to learn an entirely different system and ensures that condition data and process data are available simultaneously on the process control system. This, in turn, helps ensure that asset condition receives as much attention as process condition.

SPM Instrument AB, Sweden, launches a brand new diagnostic method in connection with Leonova™, a hand-held machine condition analyzer. Called the SPM Spectrum™, it is the result of an FFT on the time signal recorded with an SPM shock pulse transducer from a rolling element bearing. The individual bearing frequencies (BPI, BPO, 2*B2 and FT) and their harmonics are highlighted in the spectrum. This is displayed together with the measured shock value and a light signal, green, yellow or red that shows the result of bearing condition evaluation.

When troubleshooting or using vibration in a Predictive Maintenance program comparing identical machines to each other is often the best method to diagnose a problem – especially if you suspect a problem exists in one or more of the machines. When vibration data is collected on a bearing housing using an accelerometer, one is not only measuring vibration forces, but also the effect of the structure on these forces.

The maritime industry is in many aspects using maintenance strategies from the past. Land based industry used to take influence from shipping to organise the maintenance in the 70:ties. Now industry is perusing new strategies that give better reliability and are more profitable. By focusing on reliability the indirect effects from doing the wrong maintenance can be reduced considerably. Shipping industry has from a maintenance aspect been doing the wrong things correct for many years. The opportunity is now to do the right thing correct instead.
