Blood Test
This is a system of checking the 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 aluminum 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 an engine for example 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.
