Title: 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.

4
  • 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.

7
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.
