Services: Machinery Troubleshooting
| |||||||||
Improve plant reliability and reduce costs through investigation and
rectification of machinery reliability problems and failures.
Get to the root-cause of machinery problems with our structured, fact-based
approach.
Trial and error approaches to reliability problems can be expensive and
time-wasting as resources are spent on the wrong solutions. Our fact-based
root-cause analysis methods get to the heart of the problem; in fact we
routinely use these methods as part of our vibration analysis services. The
approach is particularly suited to potentially adversarial situations, e.g.
when a supplier seeks to avoid responsibility for machinery problems. We can
either carry out an investigation on your behalf or provide facilitation and
mentoring. Application of these methods brings many benefits:
• Focuses on costs and benefits up-front so that effort is matched to potential
return,
• Clear statement of problem which can be agreed on by all parties,
• Fact-based approach allows opposing viewpoints to be evaluated without
animosity,
• Encourages collaborative approach with broad participation. All participants can
see the progress
• made on the investigation and the evidence collected to date,
• At every stage the justification for particular tests is clear so clients can
understand benefits before
• committing to expenditure when specialist tests e.g. metallurgical examination,
are called for,
• Powerful cause-and-effect logic clearly identifies root causes.
Identify the causes of excess machinery vibration and solve them cheaply,
quickly and permanently.
Vibration problems are often difficult to pin down.
We have a complete toolbox of techniques to identify and solve problems:
• Identify and solve problems due to unbalance, misalignment, resonance, rubbing,
unsteady flow,
• self-excited vibrations, instability and more,
• Multi-channel transient analysis for large machines & machines with flexible shafts,
• Long-term monitoring to catch intermittent problems,
• Measurement of Operational Deflection Shapes to identify weak structures, soft
foot etc.,
• Test solutions through virtual modelling and redesign,
• Quick solution for resonance problems using dynamic absorbers.
Fast, effective on-site services for balancing of rotating machinery.
Where unbalance is the cause of excess vibration we can often carry out in-situ
balancing to avoid the need for equipment to be removed from service and sent
to a workshop.
• Single plane balancing,
• Two plane balancing,
• Balancing of flexible rotors.
