“UNDERSTANDING OIL SAMPLING”
“MAINTENANCE CONCEPTS”
There are four basic maintenance concepts:
Unplanned Maintenance Preventive Maintenance
Predictive Maintenance Proactive Maintenance
|
|
|
Unplanned Maintenance
A decision to do nothing until failure
VERY HIGH MAINTENANCE COST `
-
Overtime
-
Lost production
-
High inventory
SHORT COMPONENT LIFE &
REACTIVE MAINTENANCE
-
No time for failure analysis
-
Fix it when it breaks
-
No data to learn from
|
 |
Preventive Maintenance:
Scheduled maintenance according to time (hours) or mileage
MODERATELY HIGH MAINTENANCE COST
-
Over and under-maintained equipment
-
Time and money spent unwisely
-
Production loss from unscheduled downtime
SHORT COMPONENT LIFE
-
Repair start-up problems
-
Exposure to external contaminants
-
Unplanned maintenance
-
No root cause analysis
|
|
|
Predictive Maintentance:
Condition-based maintenance considers the unique characteristics of
each component.
REDUCED MAINTENANCE COST
-
Less overtime
-
Increased production
-
Time spent more wisely
-
Reduced repetitive repairs
INCREASED COMPONENT LIFE
-
Minor problems corrected early
-
Historical data encourages purchase of equipment
-
Down time keep to a minimum
|
 |
Proactive Maintenance:
Corrective actions aimed at failure root cause, not just symptoms,
extension of the working life of the components.
-
Analyze and anticipate rather than react and repair
-
Root cause analysis guides maintenance action
-
Trending and developing unique component signatures
-
Reliability through oil analysis / wear particle analysis
-
Improved filtration reduces wear up to 80%
-
Reduce the number of breakdown” catastrophic” failures.
-
Reduce contamination of oil by improved filtration
|
-
According to Caterpillar “dirt and contamination are by far the number
one cause of hydraulic system failures” : the system must be keep clean in order to
achieve the productivity they’re capable of. When fluid is fine filtered, hydraulic
systems life can be extended by 50 times.
-
A.C. Delco Division of General Motors also tested engines and found
an eight-fold improvement in wear rates and engine life with lower contaminant levels.
“Compared to a 40-micron filter, engine wear was reduced by 50% with a 30-micron filter.
Likewise, wear was reduced by 75% with a 15-micron filter.
The study also equates the resulting friction reduction with a 5%
increase in fuel economy.

TECH TALK
Spectro-Metals:
Glossary Description: Any of several techniques for detecting and
quantifying trace metallic elements, in which the sample is energized to make the
elements emit or absorb a quantifiable amount of light energy.
Reporting units: Parts-per-million(ppm) by weight. 1 ppm-0.0001%
Repeatability: (approx.): 1-20ppm (+/- 1ppm); 20-500 (+/- 5%); 500+(+/-
8-10%)
Technical overview: Spectro-metals is confined to the measurement
of metallic particles <10 microns in size and is thus limited on detecting catastrophic
failures. In some applications, it is a weaker alternative. There is insufficient
energy available to enable ionization of particles well below 10 microns which must
occur if spectral energy is to be developed.
Interpretation: Spectro-metals testing provides information on three
distinct areas of interest: WEAR, CONTAMINATION, ADDITIVES.
Wear metals: Iron, Chrome, Aluminum, Molybdenum, Lead, Copper, Tin,
Nickel, Silver, Antimony and Titanium
Contaminant metals: Silicon, Sodium, Potassium, Boron.
Additive metals: Magnesium, Calcium, Barium, Phosphorus, Zinc.
|
WEAR METALS
Iron: Wear Sources: Piston, rings, cylinder, gear, block, head, cam,
roller bearing, race.
Chrome: Various plating, liner, ring, some shaft gears.
Molybdenum: Ring plating, alloy (also oil additive, off shelf supplement)
Aluminum: Wear source: Piston, bushing, thrust, block, blower, cooler cores
Copper: Wear source: Bushings, bearing, piston insert, axial hydraulic piston
assembly, rod packingLead: Wear source: Bearing overlay, bearing alloy, piston inset,
wet clutch
Tin: Wear source: Bearing, piston plating or alloy
Nickel: Wear source: “heavy” fuel contaminants(usually with vanadium and
sodium), stellite(valve seat)
Silver: Wear source: wrist pin bushings, turbo bearings, needle bearings
Antimony: Wear source: bearing alloy, babbitt alloy(covering on engine bearings)
Titanium:Wear source: Gas turbine bearings/hubs/blades
CONTAMINANT METALS
Silicon: Source: Wet clutch, brake materials, dirty air intake system
Potassium: Source: Coolant additive(antifreeze)
Boron: Source: Lube additive
ADDITIVE METALS
(detergent pack or oil condition)
Magnesium: Source: Lube additive
Calcium: Source: Lube additive
Barium: Source: Lube additive
Phosphorus: Source: Lube additive; synthetic phosphate ester lube.
Zinc: Source: Lube additive

ALL TYPES OF SYSTEMS BENEFIT FROM THIS TESTING PROCEDURE. EQUIPMENT/COMPONENT HISTORY
INFORMATION CAN BE OBTAINED FROM OIL ANALYSIS TO DETECT ANY PROBLEMS BEFORE THERE
IS MAJOR DOWN TIME.
Viscosity
What causes viscosity to change?
Upward = above 16.5
-
Lube oxidation
-
Foaming/Pump Cavitation
-
Emulsion with water
-
Soot or solids contamination
Downward = below 10.0
-
Fuel or solvent contamination
-
Refrigerant
-
Wrong fill or make up of lube
“Viscosity is recommended for any application”
Fuel Soot
Glossary description: Combustion solids from reciprocating engines,
however, the primary application is diesel engines.
Cause-Operations:
Lube change intervals too long
-
Over fueling or excessive idling
-
Incorrect rack setting
-
Restricted air intake(SILICON)
-
Leaking down or worn injector

Where are you now?
If you already have a testing program or if you want to begin, we invite you to the
LubeTrak platform, a web based system offered by Megatrol. For competitive prices,
we can provide you with your test results, posted on a web page, dedicated to your
company. Results will be posted to your page each day and will remain there for historical
needs. Analysis of the results will appear as Normal , Abnormal or Critical. In
the case of Abnormal or Critical you have the option for an expert analysis, ‘Analysis
Pro’ which immediately notifies selected individuals by e-mail with recommendations
to resolve the problem. Testing for all oil type systems is available. Contact either
Jon Rose at jrose@megatrol.com or Dick Cisco
at dcisco@megatrol.com .
What are your long term goals?
We encourage you to review your machine maintenance long term goals and suggest that
regular and routine oil analysis be a part of these goals. The cost of a simple test
through LubeTrak/Megatrol will pay large dividends should a problem start to develop
that might mean a major overhaul of the equipment. Oil analysis can tell you what
is going to happen long before it happens.
Do you have vendor support?
An oil analysis vendor is a good step in the right direction: Try the LubeTrak platform,
offered by Megatrol to see how we compare! Should you have sufficient volume of tests
we offer a superior on-site analysis machine to complete your testing in house while
utilizing the advantage of the LubeTrak web based program. The notification of abnormal
or critical results from tests you do in house would still be a part of the LubeTrak
reporting package. In house testing can save you considerable money and still give
you the control you want. Contact us at the above e-mail addresses and visit us on
the web at: www.megatrol.com
