Lubrication is the process of reducing
friction. Friction, unchecked, causes wear, wastage of energy
and rising temperatures that can cause great damage to machines
and equipment, but it will never be completely eliminated.
The single important criteria of lubrication is the maximum
reduction of friction.
Lubrication is the key to reducing energy
wastage and parts deterioration. Wear reduction can become
the key to maintaining mechanical equipment at their optimum
efficiency and to extending machine life.
Lubricants can be either gas, liquid, solid
or synthetic. They are important in keeping contaminants from
delicate machinery parts in environmentally-polluted areas.
Heat build-up is a major problem area for maintenance engineers
as machines work longer and faster without stoppage. Special
additives are increasingly important to help reduce generated
heat which would otherwise cause the machine to break down.
The direct results of lubrication:
- Retardation of wear
- Minimisation of temperature rise
- Reduction of friction
- Longer machine life
- Reduction in downtime
- Lower production costs which result from uninterrupted
machine operation, lower maintenance costs and less need
to replace parts.
Effective lubrication
To maintain efficient and continuous performance of plants,
factories and workshops, it is essential to set up 'corrective'
and 'preventive' maintenance systems.
Corrective maintenance is when slight
damage to equipment or machinery occurs. It encompasses the
repair of the part and is generally the policy in smaller
industries which have a small number of machines and any damage
would not normally affect the flow of production.
Preventive maintenance is directed
towards getting the longest period of machine performance
without problems or damage which would cause a disruption
of production flow. With effective preventive maintenance,
it is possible to maintain maximum efficiency in industrial
production with minimum time loss caused by interruptions.
This makes it possible to obtain the lowest cost for the final
product.
Preventive lubrication is perhaps
the most important aspect of preventive maintenance: From
statistics collected over many years, Omega researchers have
calculated that general maintenance costs about 5-10% of the
total operational cost and the maintenance lubrication costs
only 2.5% of the general maintenance cost. In other words,
the cost of maintenance lubrication when compared with the
total cost of production, comes to between 0.125-0.25%.
Analysis by Omega Manufacturing Division
of maintenance lubrication needs show that this is the main
support of general preventive maintenance program and that
inadequate lubrication will cost disproportionately more than
the money foolishly saved by using low-quality lubricants.
Benefits of adequate lubrication
Modern machinery is complicated, compact and requires precise
adjustments in operating conditions that are severe and varied.
This has resulted in a great number of different types of
lubricants being used, but it takes a great deal of attention
and effort to ensure proper application.
Cost saving - the savings possible
Omega lubricants are about 100 times the cost of lubrication.
Performance observation - Better quality
Omega Lubricants last longer even working at maximum speeds
and generally, lesser quantities are required to do the job
than with a less expensive lubricant.
Maintenance costs - High quality Omega
Lubricants result in less replacement parts and less damage
to machinery.
Minimum breakdown - Breakdown is not
only expensive to repair but also very costly in terms of
production failure. This is true not only in highly-automated
factories, even a small farm that has a tractor down can lose
a lot of money. Lubrication with Omega cuts down the number
of breakdowns dramatically.
Less production rejection - Many products
are rejected when undergoing inspection. Many rejected products
are the direct result of the machinery not performing according
to plan because of wear due to inadequate lubrication.
Preventative lubrication program
The first step to ensure proper lubrication is to develop
an Omega lubrication program. First, you need to:
- Determine lubrication intervals
- Classify and code the different lubricants required
- Establish a recording system
- Draw up lubrication routes
- Form a central archive for control
- Set up intervals for lubrication
- Set up daily record of lubrication
- Ensure an adequate stock of Omega lubricants
