3. Systematic Preventive Maintenance
Owing to the challenging work environment at
various industrial sites worldwide, some of the
proposed systematic preventive maintenance
measures helpful in optimising equipment energy
efficiency include:
●●
500 hours engine oil change and
●●
1,000 hours hydraulic oil change.
The frequency towards equipment preventive
maintenance has to be site specific since some
of the work conditions are very demanding. The
site specific maintenance service schedule could
include the following items:
●●
primary and secondary air intake filters,
●●
engine lubricating oil filter,
●●
primary and secondary fuel filters, and
●●
water separator and brake oil filter.
4. Lubricating Oil and Coolant Analysis
Systematic scheduled analysis of the lubricating
oil and coolant for any site equipment will
assist management towards in-depth detailed
understanding of equipment performance.
Figure 5 shows an example of the results from
a lubricating oil and coolant analysis - Overall
Machine Criticality Risk Profile Matrix. Some
of the useful information obtained from this
crucial equipment analysis includes component
wear rate, oil condition and cleanliness after a
designated period of usage, optimisation in the
economic frequency of oil change and the study
on the option in using extended life coolant.
The benefits of using extended life coolant
include cost savings via increased equipment
component life, less maintenance required
and also reduction in stress to the environment
since less coolant is used thus less is disposed.
The proposed usage of this unique engineered
Biodegradable Hydraulic Oil, formulated from a
fully saturated Hydraulic Environmental Synthetic
Ester base stock and selected additives, for
daily equipment operations would be helpful in
resisting high-temperature oxidation, excessive
wear conditions and corrosion prevention. Other
advantages of this special oil is that it offers
applications over a broad range of temperatures,
possess a high viscosity index, offers excellent
cold flow characteristics and
does not affect conventional seal
materials. After usage this special
biodegradable hydraulic oil can
eventually be decomposed by soil
and water microorganisms.
