Description

FLUID ANALYSING SYSTEM TECHNOLOGY
The present invention regards a device for monitoring status of a power unit comprising a fluid circuit. All engine power units in use throughout the world, be it in an aircraft, marine shipping, marine offshore power systems, land power systems, transport down to automobiles, rely on regular maintenance to maintain the engine power unit in first class operational state.
All reciprocating, turbine, and jet, type power units run through a lubrication process that allows high and low speed rotating equipment to convert a rotational force into movement through a drive arrangement be it mechanical or compression and propellant. The lubrication of all these systems prevent heat and friction build up between rotating contacting metals, by inlaying between contacting metals and forming a thin film of oil that allows for force to be transferred without excessive heat and friction which otherwise would very quickly fuse metal together and destroy the power unit completely. It can be said that the lubrication system of "any" power unit is the lifeblood of the designed system, without which no power unit in the modern world could function.
It is therefore extremely critical that a lubrication system to all this type of equipment is maintained in a first class condition, throughout the life of the system.
Traditional maintenance to the lubrication system is usually carried out on a regular pre-determined time scale where the lubrication oil is changed for new thereby maintaining the lubrication co-efficient properties and through a filtration system that removes any dirt particles to a degree while the unit is in use. Regular pre-determined samples taken from each system which are then sent for laboratory analysis is another method that through the returned reports on the condition of the lubricating oil sample can allow for extended further use of the power unit if the sample is shown to be in an acceptable condition with regard to:
> Lubricating efficiency (no or little degradation of the oil properties) > Excessive carbon build up
> Excessive metals build up
> Excessive dilution of the oil (water ingress)
> Excessive sulphates build up.
All of these maintenance programmes are designed to keep the unit in a "Fit for Purpose" and safe state. However they are costly and time taking inasmuch that changing the lubricating oil on a regular basis are sometimes not required on the time schedules set adding to operational costs.
Regular sampling takes time to present results and in some cases is too late to prevent engine power unit failure due to the time before results are returned to the customer. Any breakdown of internal systems in the power unit is not readily apparent during these times.
From DE 10053069 is known to determining the quality of lubricating oil used in an internal combustion engine (IC) comprises acquiring parameters which give feedback on the quality of the oil, and testing the oil using spectrometry. The measuring system comprises a light source which is directed onto the gap through which oil passes, a receiver for measuring the radiation, and an evaluating electronic device.
An aim with the present invention is to provide a system for monitoring the status of a power unit, which is easier and more reliable than previous methods. It is also an aim to provide a device for determining abrasion of different parts of the engine through mechanical wear of component parts down to the molecular structure. It is also an aim to provide a device which may be used on any type of engine power unit.
