Studies on the Dust Proof Faculties of Air Cleaner on Farm Eengines (Part III)

On the Faculties of Oil-bath air Cleaner

Abstract

The influence of several factors upon the operation of the oilbath air cleaner of farm engines was investigated and the following facts were found.
1. The dust proof faculty of the cleaner advances with the increase of oil depth in the cleaner shell: the faculty at maximum depth is superior as much as 18 percent to that at minimum.
2. The faculty in question is affected by the viscosity of mobile oil in the cleaner shell: it decreases as far as the certain degree of decline of the viscosity, but beyond that, on the contrary, increases.
3. Mobile oil in the cleaner should be renewed when the contamination amounts to 20%. At the contamination of over 30% diminishes the faculty remarkably.
4. The air capacity diminshes in proportion to the excess amount over 60-65 grams of dust particles supplied to the cleaner.
5. The annexation of mobile oil to the element raises the dust proof percentage. It will therefore be attributed to the adherence of oil to the element under tremulous circumstances that this sort of cleaner sustains its high faculty.
6. So far as the same sort of dust is concerned, the dust particle is, the more it passes through the cleaner.
7. The injurous effect of the farm dusts tested on the dust proof faculty is less in the order: soil dust>BHC powder>slaked lime.
