Specialist in blending oils
This is a system of checking used oil taken from an engine or piece of equipment
for its condition, since wear and contamination from other sources will collect in
the oil as it goes about its business of lubrication.
Oil is the only part inside an engine that is in physical contact with all internal
surfaces. That is why we call this service a Blood Test. The principle of our Blood
test oil analysis for condition monitoring is that all components of engines and
industrial equipment such as hydraulic systems are manufactured with different metals
and alloys, with aluminium pistons, mild steel & chromium plated piston rings and
bearings containing copper/lead or bronze surfaces.
All machines wear under normal conditions, and wear is the action of rubbing off
these surfaces. The oil collects these minute wear particles and holds them in suspension
until the drain plug is removed and the oil changed. The rate at which equipment wears
is governed by a whole host of elements, i.e. the harshness of the way it is driven,
the environment in which it is working, such as a quarry or on the sea where the
air drawn into the engine will contain different types of contamination.
The Blood Test analysis measures the rate of change of these contaminates and draws
up a history or wear curve of the engine/equipment, and when there a change in the
slope of the curve it is normally an indication that something is wrong. With careful
consideration of all the conditions an indication of where and when problems may
occur can be forecast.
