Cost is low, it is easy to maintenance the advantages of, be widely adopted.The filtering efficiency of oil-bath filter under normal conditions imitate by filtering
Rate is 95-96%, and the filtering efficiency of paper filter core is up to more than 99.5%.
In addition, when engine is operated, air inlet is interrupted, so that cause the air vibration in air filter housing,
If air pressure fluctuation is too big, the air inlet of engine is influenceed sometimes.
Utility model content
The utility model is simple there is provided a kind of structure for existing issue and the deficiency for the technology presence for solving existing issue
Single, the Novel diesel engine air cleaner that smoothing effect is good, noise is small.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：A kind of air filter for diesel engine, including filter
Clear device case, strainer cover, filter core component, filter element structure is equipped with the inside of the filter case and strainer cover
Part, the internal material of the filter core component includes filter core and filter paper, and filter core is arranged on the position of filter, filters
Paper, which is arranged far from the inside of the position of filter, the filter case being fixed with dividing plate, the dividing plate, is provided with bloop.
The technical program has the technical effect that one side gas can be reduced by the bloop of dividing plate, on the other hand
Dividing plate can fix filter core component, prevent from rocking.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement, in dividing plate and the cleaner
The corresponding hole in two positions is provided with case, corresponding two device to hole in position is passed through by flange bolt, and then by dividing plate and filtering
Device case is fixed.
Further, filter, filter are provided between the strainer cover and the filter core component
Top and bottom and strainer cover on the inside of top and bottom fix, the filter includes fixed support and being covered in
Screen pack on fixed support, the mesh of screen pack can stop object larger in gas, be the first heavy filtration effect, with filter core
For the second heavy filtration, filter paper is triple filter, progressively filters out less and less particle.In addition, screen pack can also play solid
Determine the effect of filter core component.
Further, the top and bottom on the inside of the strainer cover are provided with linear type groove, the fixation of the filter
The top and bottom of support are provided with the projection matched with groove.
Further, top and bottom on the inside of the strainer cover are provided with least one groove, and the filter is consolidated
The top and bottom of fixed rack are equipped with least one projection with groove match.
Further, the strainer cover is provided with many equally distributed air admission holes, and the filter case is provided with outlet
Mouthful.
Further, the top and bottom of the filter case and strainer cover are fixed by screw or buckle.
To sum up, the beneficial effects of the utility model are：(1) using dividing plate and set bloop can noise reduction and solid well
Determine filter core component；(2) smoothing effect is good, sets filter as the first heavy filtration, using filter core as the second heavy filtration,
Filter paper is triple filter, and the particle differed in size in gas is filtered out comprehensively；It effectively prevent what impurity was caused to diesel engine
Damage, substantially increases the service life of diesel engine；(3) the utility model good appearance, simple in construction, maintenance, easy maintenance.
