The oil driven centrifuge is a well proven technology which has provided industry with a cost effective method of cleaning oil in a wide range of applications for many years.Tweet
Originally designed for use on engines, its use has expanded to all types of applications where the importance of contamination control has become apparent.
Whilst the centrifuge is not an oil filter, it is not limited to the integrity size rating of a filter element and consequently will remove particles to sub micron levels. On the other hand it is totally ineffective at start up until the oil has warmed and rotor has reached high speed to become effective in causing the particles to migrate to the outside of the rotor. Consequently at start up, no cleaning action occurs.
The dirt holding capacity of the rotor is well beyond that of a comparable sized element with the rotor being washable and re-usable – A great saving on the environment by reducing land fill.
The centrifuge creates gravitational forces within the rotor which cause the more dense contamination particles to migrate to the outer perimeters of the rotor shell. As the oil’s return path is toward the centre of the rotor, where the ‘G’ forces are less, the particles remain trapped in the high ‘G’ area where they are removed at a later date when the rotor is cleaned.
For the particle to be removed, it must be more dense than the flowing oil, consequently the additive package of the oil will not be effected unless it also is more dense than the oil. If this were the case, the additives would settle on standing which would be detrimental to the quality of most oils. This is in fact the case in a small number of oils such as those containing Molybdenum Disulphide which will settle on standing, consequently cannot be cleaned in the oil centrifuge – the molybdenum being a heavier metal will be removed from the oil.
The oil driven centrifuge comes in many models and is adaptable to most sized diesel engines. They are a highly regarded device sought by many engine OEM’s – Caterpillar sell them over the counter, Mack have a built in canister for their engines, Cummins have a retrofit cone version, MTU fit them above their filter head, Scania use them as a standard engine filter. Large Wartzilla engines have centrifuges fitted as standard.
Centrifuges are well known to maintain pristine oil condition by constantly removing the soot and other contamination particles as the engine operates, thus maintaining a much cleaner oil condition than can be achieved by normal filtration.
Most engine oil filters are rated at around 30 um which is about ½ the size of a fine hair. Any particle smaller than 30um will consequently stay in circulation causing gouging and wear on components as it is carried around the system as it operates. Soot particles are likened to dust and usually run around 0.5 to 2µm in size. Their abrasive ability is likened to dust and consequently cause higher wear rates. The oil driven centrifuge is well known to constantly remove soot particles and hence reduce wear.
Centrifuges are available in many sizes to fit all different sized engines – a very rough guide is as follows :-
Are you throwing away perfectly good oil because of worries about contamination? Here’s a better solution. If you’re looking to minimise your oil expenditure while giving your machines the maximum quality lubrication, the answer is cleaning your oil with a centrifuge. Oil centrifuges are a proven, cost effective technology that’s been used in an array of industries for years.
Clean Oil Services offers you a way to constantly remove impurities from your oil while the machine is running. The result is oil you can use for longer and no machine downtime for oil replacement. This offers a very effective fleet solution to reduce your running costs.
How Centrifuges Work
They work in a simple but powerful manner. Oil circulates from your machine into the centrifuge in a dialysis system. Inside the centrifuge, an oil driven rotor spins at high speeds of up to 7000 rpm. The resulting gravitational force draws any particles in the oil outwards while the purified oil passes back into your machinery. This way, soot and other contaminants are continually removed from the oil during normal engine operation. You then remove the contamination when you periodically clean the rotor.
Oil Centrifuge Benefits.
Lubemaster Centrifuge Oil Cleaning System
Australian firm Clean Oil Services is the developer of the innovative Lubemaster portable oil-cleaning centrifuge. We offer a range of models with flow rates ranging from 10-70 litres of oil per minute.
If you want to stop throwing away perfectly good oil because of contaminants, you now know a smart and economical way. Just contact Clean Oil Services for details of our oil centrifuges and
Clean Oil Services provides a comprehensive preventative maintenance program for all your lubrication needs. We offer a one-report system for condition monitoring, contamination control, lubrication, and wear management.
When operated in conjunction with a comprehensive oil analysis program, it is possible to achieve indefinite oil drain on clean burning engines using today’s low sulphur diesels by the following:-
• If the particle levels of the oil are kept low within limits
Why do we need to change oil?
What about the effect of Exhaust Gas Recirculation systems (EGR).
Why would we want to increase the soot carrying ability of the oil when the centrifuge will constantly remove these particles as the engine operates?
