Lubrication - Centrifugal oil-filter
|For trucks, marine Diesels, tractors, construction site machines . . .|
There has always been oil-cleaning through centrifugal forces, Earlier on even in normal motor cars. One had to open them up regularly and scrape everything out. Nowadays it's different, one simply replaces the inner
|Functions after the sprinkler principle.|
The absolutely necessary rotation occurs by mounting the centrifuge on a rotating part, e.g., on the front end of the crankshaft. Nowadays if possible, this component is charged with the full oil-pressure and as soon as
it's full, the oil escapes from the rotor through two tangential bores with free-flow jets.
|Particles of less than 0,25 thousandths of a millimetre can be filtered out.|
So, the oil-pressure is responsible for the fast rotation, the fact that it's fitted with ball-bearings does the rest. The manufacturer maintains that 90% of the dirt particles in the oil are smaller than one 2-thousandth of a
millimetre. These are filtered out by a centrifuge having a rotation speed of up to 10.000 RPM.
|Only about 5 percent in the main current..|
This fine-filter has always been mounted in the oil by-pass flow. Although it does require the full oil-pressure, the oil taken in must be retained for a certain amount of time. Apart from this, if the oil through-flow were too
strong, the fine particle deposits on the walls would again be drawn into the circulation.
|In the case of later installation, no more than 15° inclination.|
The longer inspection intervals, which are typical for trucks, are supported by such a thorough oil cleaning. Should the protection period of the centrifuge not be long enough, then larger and even several are possible,
e.g., three filters strategically placed.
|A maximum volume of more than 5 litres is possible.|
If during the servicing, the oil has leaked out, only the rotating dirt chamber has to be replaced. Your hands can remain relatively clean and the job is done in a lot less time. One further point, the dirt containers should
be able to be disposed of, e.g., in an incineration plant. 04/14
