Maintaining a precise
rotor balance quality is an integral part of keeping machinery vibration at
acceptable levels, and, more importantly, is essential to minimizing
mechanical stress and maximizing long-term reliability.
In keeping with our
“Maintenance that Matters” philosophy, M&B specializes in directing the
on-site balancing of all types of rotating machinery. We have the experience
to achieve precise balance results quickly and economically. Whether it is critical
high-speed turbo-machinery or balance of plant machinery, we can get it
running smoothly.
Because rotating unbalance is a common problem, balancing is often
misapplied by other analysts when proper data analysis techniques are not
used. We avoid this by starting with the correct transducer type for the machine and bearing
design. Combined with single or multi-plane balance solutions, mode shape
analysis, least squares analytical optimization, and graphical data
analysis, we provide excellent quality balance results in short order,
reducing downtime and maintenance costs.
Our extensive
field experience ensures balancing is only performed when
truly necessary. We
analyze steady state and transient speed vibration data to assess the rotor’s on-line
and resonance response characteristics. By analyzing rotor responses during
both operating conditions, we can properly compensate data for the runout,
thermal influences, and process effects that often affect the vector data,
thus gaining accurate insight into the true dynamic rotor response.

To document the dynamic
machinery responses, both ‘before’ and ‘after’ vibration data are provided
as part of the project report. This data, in conjunction with the balance
plane and weight information, is used to calculate the direct and
longitudinal influence vectors. These influence vectors can be later
utilized to expedite balancing,
often allowing a “one
shot” trim balance to be performed to quickly return a machine to operation.
As part of our
methodology, all balance planes are graphically documented using AutoCAD.
These ‘weight maps’ identify all existing weights found, all additions or
modifications made to each balance plane, and the size and configuration of
each weight type. The weight maps are an excellent reference for future
maintenance.

Technical Training
We also offer an
excellent 3-day Machinery Balancing Seminar,
with hotels seminars conducted periodically throughout the country. We can
also perform a custom, on-site course at your facility. |
