The Life of Rotational Equipment

The Life of Rotational Equipment
2

• Lubrication oil cleanliness is probably the
  single most important factor determining your
  rotational equipment longevity.

3

• The British Hydromechanics Research Association
  (BHRA) conducted a three year controlled field
  study of 117 hydraulic machines. The field trial
  was established with the sole purpose of
  correlating fluid cleanliness to breakdown
  frequency. The results published are extremely
  compelling and worthwhile heeding.

• You would assume that operating machinery within
  oil cleanliness specificationsshould assure that
  the life of the equipment is reasonable, RM is
  fair and downtime minimised.

5

• But what if the lube circuit oil is maintained at
  several levels of cleanliness above the norm?
  The answer is surprising and the BHRA study shows
  that based on a datum of ISO 18/15 oil that oil
  that is two grades cleaner will outperform the
  datum oil by 1.8x reliability based on
  breakdowns.

6

• If the oil is running dirtier at ISO 22/19 then
  breakdowns are far more frequent and more than
  twice as problematic.

Research

• In the 1990s Nippon Steel implemented a
  hydraulic system contamination control program
  plant-wide, involving both improved filtration
  and rigorous fluid cleanliness monitoring, and
  pump replacement frequencies were reduced to one
  fifth and the cumulative frequency of all
  tribological failures (i.e., failures relating to
  wear and contamination) were reduced to one tenth.

8

• Kawasaki Steel also implemented a similar oil
  contamination control program and almost achieved
  a 97 reduction in hydraulic component failures.

9

• Such claims as these spurred the British
  Hydromechanics Research Association (BHRA) and
  the U.S. Navy to conduct their own controlled
  studies to substantiate benefits of proactive
  contamination. 

10

• The BHRA study covered a three-year period and
  was based on the carefully monitored field
  experience of 117 hydraulic machines across
  various categories (i.e., injection moulding,
  machine tools, material handling,
  mobile/construction, marine, metal working, test
  stands, and miscellaneous).

11

• The results of the study showed a dramatic
  relationship between fluid contamination levels
  and service life. Improved system cleanliness
  achieved extended actual mean time between
  failures (MTBF) from 10 to 50 times, depending on
  cleanliness. 

12

• A study by the Naval Air Development Centre in
  Warminster, Pennsylvania performed on aircraft
  hydraulic pumps showed nearly a 4-fold wear-life
  extension with a 66 percent improvement in
  filtration and a 13-fold wear-life extension with
  a 93 percent improvement in filtration.

Solution

• BioKem has the equipment to perform on-site oil
  purification to rectify post-event lubrication
  circuit contamination without discarding the oil
  and installation of conditioning vacuum
  dehydration equipment running kidney loop
  filtration.

15

• BioKem can also presecribe and supply static
  solutions to resolve chronic oil cleanliness
  concerns. Should you require a professional
  service to filter or HOF your circuitry, spools,
  coolers, lube tanks, manifolds then contact
  BioKem Oil Services.

16

• The chart also shows that the new clean oil
  received from a supplier is typically ISO 21/18,
  and potentially harmful to your machinery if not
  polished before first use.

17

• If you suffer an event that compromises the
  cleanliness of your oil contact BioKem and seek
  advice as the oil can be recovered, dehydrated,
  filtered and polished so that it exceeds a new
  oil spec a cheaper and possiblyquicker solution
  than ordering new oil.
