Abstract
The utility model belongs to the field of air filtering technique, and relates to an air filter for a diesel generator. A bottom cover of the air filter is butted with a cover to form a housing of the air filter; a filter core is fixed in the housing; an air inlet cavity is formed between the outer surface of the filter core and the inner wall of the housing; an air inlet is formed at the periphery of the housing and communicated with the air inlet cavity; an air outlet is formed on the bottom cover of the air filter and communicated with the inner cavity of the filter core; and a glass fiber cotton layer is arranged on the outer surface of the filter core. The air filter of the diesel generator has the advantages of light weight, high air flowability, small air noise and high corrosion resistance.
Description
Technical field
The utility model belongs to the air filtering technical field, refers in particular to the empty filter of a kind of diesel generator.
Background technique
Need air in the cylinder during engine operation of diesel generator, contain many foreign matters and enter in the air in the diesel engine, airborne foreign matter enters the heavy wear that cylinder can cause cylinder; Airborne foreign matter enters the heavy wear that also will cause in the engine motor oil between friction pair; Therefore at the suction port of motor air-strainer is installed generally, yet air-strainer of the prior art exists some shortcomings: the air current flow performance is bad, and induction noise is big, and self is heavier, and is perishable.
Summary of the invention
The purpose of this utility model provides that a kind of self is lighter, and the air current flow performance is good, and induction noise is little, the empty filter of corrosion resistant diesel generator.
The purpose of this utility model is achieved in that
The empty filter of diesel generator, empty filter bottom docks with outer cover and forms empty filter housing, in housing, be installed with filter core, the outer surface of filter core and inner walls form air-inlet cavity, being provided with suction port on the housing periphery communicates with air-inlet cavity, empty filter bottom is provided with the air outlet that communicates with the inner chamber of filter core, is provided with the layer of glass cotton at the outer surface of filter core.
Above-mentioned filter core is: be provided with the two-layer annular core frame that is evenly equipped with circular aperture between two end cap, between two-layer annular core frame, be provided with collapsible filter paper, the bottom of filter core is annular panel, the annular panel only covers the end region between the two annular core framves, the loam cake of filter core covers the end region at two annular core framves and middle part, and the middle part of loam cake is provided with mounting hole.
Be provided with seal arrangement between above-mentioned filter core two end cap and the housing.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model makes the engine intake of generator directly pass the perisporium of filter core, makes the utility model air current flow better performances when air inlet.
2, the utility model is provided with glass fibre cotton between the periphery wall of filter core and housing, makes the gas that enters directly not clash into the annular core frame, and the utility model induction noise is less.
3, the utility model self is lighter, and is not perishable.
