Vibration that appeared after a repair or component change.<\/strong> Any
\nwork that changes the rotating assembly’s mass distribution \u2014 a replaced gearbox,
\nbearing or bowl component \u2014 can introduce unbalance if the assembly was not re-balanced
\nafterward.<\/li>\n<\/ul>\nThe engineering services machine shop behind the balance work<\/h2>\n
Achieving a specific balance grade sometimes requires more than adding or removing a
\ncorrection weight \u2014 a shaft may need re-machining to correct a mounting surface, or a
\ncorrection may call for a custom-fabricated weight to fit a specific plane on the
\nassembly. Sentrimax’s engineering services and machine shop capability \u2014 milling,
\nlathe-turning and precision-grinding \u2014 supports the balancing process itself when the
\nassembly’s geometry calls for it, rather than treating balancing as a bolt-on step
\ndisconnected from the rest of the repair.<\/p>\n
Balancing across all serviced brands<\/h2>\n
Balancing is not brand-specific. Sentrimax balances rotating assemblies from
\nSharples, Flottweg, Centrisys, Derrick, GEA, Alfa Laval, Tomoe, Andritz, Bird, Pieralisi
\nand other manufacturers’ decanter and tricanter centrifuges to the same ISO G 0.5
\nspecification, as an independent MRO provider not affiliated with, authorized by, or
\nendorsed by any of these manufacturers.<\/p>\n
What you receive with a balanced rotating assembly<\/h2>\n
Every job Sentrimax completes includes a fit evaluation, a detailed inspection report,
\ndynamic balancing, and a test run \u2014 balancing and the report that documents it are
\nstandard, not an upsell. The balance work itself is verified through a three-plane
\ndynamic balancing process to ISO G 0.5, and the test run confirms the balanced assembly
\nperforms correctly under actual running conditions before the unit ships.<\/p>\n
Balancing across the equipment Sentrimax services<\/h2>\n
The same ISO G 0.5, three-plane balancing approach applies across the 8 to 43 inch
\nbowl diameter range of decanter, tricanter and disc stack centrifuges Sentrimax
\nservices, and across the major brands it works on \u2014 Sharples, Flottweg, Centrisys,
\nDerrick, GEA, Alfa Laval, Tomoe, Andritz, Bird, Pieralisi and others. The balancing
\nprocess does not change based on brand; it changes based on the physical geometry and
\nmass distribution of the specific rotating assembly in front of the technician.<\/p>\n
When balancing is requested on its own<\/h2>\n
Not every balancing job originates from a full rebuild. A rotating assembly that has
\nhad a component replaced elsewhere, or one where vibration has developed without an
\nobvious mechanical cause, can be sent in specifically for balance evaluation and
\ncorrection. The same inspection-first approach applies: the assembly is measured before
\nany correction weight is added, so the actual unbalance condition is documented rather
\nthan assumed.<\/p>\n
Why the inspection report references balance condition even before repair<\/h2>\n
The initial inspection at receipt notes visible indicators relevant to balance
\ncondition \u2014 uneven wear patterns, buildup on the bowl or scroll, or damage that would
\nshift mass distribution \u2014 even before any repair work is approved. This gives an early
\nread on whether balancing is likely to be a straightforward correction or a more
\ninvolved one once the assembly is fully disassembled, and it is documented in the same
\ninspection report that covers the rest of the machine’s condition.<\/p>\n
How balancing fits alongside welding, fabrication and controls work<\/h2>\n
A rotating assembly rarely arrives needing only balancing. It is common for a job to
\ncombine welding and fabrication to correct wear or damage on the bowl or scroll,
\nmachining to bring components back to tolerance, and controls work if a VFD or PLC issue
\ncontributed to the problem, alongside the balancing itself. Balancing is sequenced after
\nthat other work is complete, since it corrects the assembly in the exact configuration it
\nwill actually run in \u2014 not a configuration that will change again once other repairs are
\nfinished.<\/p>\n
What to describe when you contact us about vibration or balance concerns<\/h2>\n
If vibration is what brought you to this page, a useful starting description includes
\nwhen the vibration started, whether it changes with running speed, whether it appeared
\nafter any other repair or component change, and whether it is localized to one area of
\nthe machine or general. That context, combined with a physical inspection, is what
\ndetermines whether the issue is genuinely a balance condition or something else
\nentirely, such as a bearing defect or a mounting issue unrelated to the rotating
\nassembly’s mass distribution.<\/p>\n
Request balanced rotating assembly work<\/h2>\n
Whether you need a full rotating assembly rebuild or a standalone balance check on an
\nassembly you already have, tell us about your centrifuge and what you are seeing.<\/p>\n\nPreguntas frecuentes<\/h2>\n\nIs dynamic balancing included in every Sentrimax repair, or is it a separate charge?<\/summary>\n\n
Dynamic balancing and a test run are included on every job Sentrimax performs, along with a fit evaluation and a detailed inspection report. It is not an optional add-on quoted separately from the repair itself.<\/p>\n<\/div>\n<\/details>\n\nCan a rotating assembly be balanced without a full rebuild?<\/summary>\n\n
Balancing is normally performed as part of stage two of the repair process, after any needed parts work is complete and the assembly is in its final reassembled configuration. Whether a standalone balance check makes sense without other repair work depends on the assembly's condition, which inspection would confirm.<\/p>\n<\/div>\n<\/details>\n\nWhat is the difference between ISO G 0.5 and three-plane balancing?<\/summary>\n\n
ISO G 0.5 describes how tight the final result has to be \u2014 the permissible residual unbalance for the rotor's mass and speed. Three-plane balancing describes the method used to get there \u2014 correcting unbalance at three points along the assembly rather than one or two, which a long rotor requires.<\/p>\n<\/div>\n<\/details>\n\nDoes balancing get redone if a gearbox or bearing is later replaced?<\/summary>\n\n
Yes. Any change to the rotating assembly's mass distribution \u2014 including a gearbox, bearing or bowl component replacement \u2014 changes the balance condition, so balancing is performed again on the reassembled unit as part of that repair, not skipped because it was done previously.<\/p>\n<\/div>\n<\/details>\n\nHow is balance verified before the centrifuge ships?<\/summary>\n\n
After dynamic balancing, the assembled centrifuge goes through a quality control inspection and a full test run that produces a performance report, confirming the balanced assembly runs correctly under actual operating conditions rather than relying on the balance measurement alone.<\/p>\n<\/div>\n<\/details>\n<\/section>\n\nHable con un especialista en centr\u00edfugas.<\/h2>\n
