Abstract
The utility model relates to an air filter for a diesel engine suitable for plateau areas. The air filter comprises a primary filter on an upper part and a secondary filter on a lower part, wherein the primary filter and the secondary filter are communicated with each other through an air inlet channel which passes through the primary filter and the secondary filter; a filter element is filled in the primary filter; the secondary filter comprises a main shell; a filter element is filled in the main shell; a connecting port connected with the diesel engine is arranged on the main shell; and the bore diameters of the primary filter and the secondary filter are more than 100mm. The air filter for the diesel engine suitable for plateau areas provided by the utility model has a simple structure; the air inflow of the diesel engine is increased by increasing the bore diameter; the plateau property of the diesel engine is improved; the combustion efficiency is increased; the combustion is thorough; the power is increased; and the environmental protection property is increased.
Description
Technical field
The utility model relates to sky filter technical field, especially a kind of diesel engine air-strainer that is applicable to the plateau section.
Background technique
Airborne dust etc. are the main roots of cylinder jacket of diesel engine, piston, piston ring, valve and valve guide bushing and the wearing and tearing of other moving parts.The effect of air-strainer is to prevent the grains of sand and dust inflow engine gas handling system; Cylinder, piston and the piston ring of maintenance motor; Make the engine fuel sufficient combustion working life of prolongation motor; In order to avoid remove the wearing and tearing of dust to motor, and then guarantee the effective performance of engine power and the prolongation in working life, reduce pollution simultaneously to environment.
Air-cooled diesel engine has the convenience of startup, economical operation, to advantages such as environmental suitability are strong, is widely used in fields such as farm machinery, engineering machinery, Transport Machinery and generator set.China's plateau section air pressure is low, and oxygen content is low in the air, causes air-cooled diesel engine deficiency of air, underpower, speed not to increase, situation such as acceleration is poor, fuel consume increase, over-emitting black exhaust befouling environment.
The empty filter of available technology adopting mainly contains following several kinds of structures, and 1, dry-type air cleaner, owing to have the papery filter core, so be prone to stop up, maintenance bothers; 2, oil bath combined type air-strainer, though be difficult for stopping up, filter efficiency is low; 3, awl hat type air-strainer is simple in structure, but filter efficiency is low.
The empty filter of air-cooled diesel engine employing now is the empty filter of secondary; Comprise the primary filter on top and the secondary filter of bottom; Be communicated with through the gas-entered passageway that is arranged between the two between primary filter and the secondary filter, have the connection mouth that connects diesel engine on the secondary filter.The aperture of the secondary filter of primary filter of the prior art and bottom is 90mm～95mm, and this structure causes the diesel engine intake quantity not sufficient, the inadequate main cause of burning.And also have air inlet tube between connection mouth and the diesel engine, cause air inlet to have some setbacks, noise is bigger.
The model utility content
The technical problem that the utility model will solve is: cause the diesel engine intake amount to reduce in the plateau section in order to solve empty filter of the prior art; The inadequate technical problem of burning, the utility model provides a kind of diesel engine air-strainer that is applicable to the plateau section.
The utility model solves the technological scheme that its technical problem adopted: a kind of diesel engine air-strainer that is applicable to the plateau section; Comprise the primary filter on top and the secondary filter of bottom; Be communicated with through wearing the gas-entered passageway that is filled between the two between primary filter and the secondary filter, be provided with filter core in the described primary filter, described secondary filter comprises main casing; Be filled with filter core in the main casing; Have the connection mouth that is connected with diesel engine on the main casing, have on the described connection mouth and the diesel engine flange connecting, the aperture of described primary filter and secondary filter is greater than 100mm.
Further, the aperture of described primary filter and secondary filter is 100mm～150mm.
For improving the filtering effect of primary filter, the filter core in the described primary filter has two-layer, is respectively the thick sponge of lower floor and the thin sponge on upper strata.
The beneficial effect of the utility model is that the diesel engine air-strainer that is applicable to the plateau section of the utility model is simple in structure, through increasing the aperture of primary filter and secondary filter; Increase the air inflow of diesel engine; Improve the plateau performance of diesel engine, improve combustion efficiency, burning fully; Power improves, and improves environmental-protecting performance.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the diesel engine air-strainer assembling stereogram that is applicable to the plateau section of the utility model;
Fig. 2 is the three-dimensional exploded view of the utility model;
Fig. 3 is the three-dimensional exploded view at another visual angle of the utility model.
Among the figure: 1. primary filter, 11. loam cakes, 2. secondary filter, 21. connection mouths, 22. lower covers, 3. gas-entered passageway.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Fig. 1-the 3rd, the diesel engine air-strainer most preferred embodiment that is applicable to the plateau section of the utility model; Comprise the primary filter 1 on top and the secondary filter 2 of bottom, be communicated with through the gas-entered passageway 3 that is located between the two between primary filter 1 and the secondary filter 2, be filled with filter core in the primary filter 1; Secondary filter 2 comprises main casing; Be filled with filter core in the main casing, have the connection mouth 21 that is connected with diesel engine on the main casing, have on the connection mouth 21 and the diesel engine flange connecting; The aperture of primary filter 1 and secondary filter 2 is greater than 100mm, and optimum scheme is: the aperture of primary filter 1 and secondary filter 2 is 100mm～150mm.
Fig. 2 is shown in Figure 3, and primary filter 1 is the branch body structure with secondary filter 2, and primary filter 1 has loam cake 11, and secondary filter 2 has lower cover 22.
When the utility model is that diesel engine connects, can save air inlet tube, make air inlet smooth and easy, noise reduces.
Filter core in the primary filter 1 of the utility model has two-layer, is respectively the thick sponge of lower floor and the thin sponge on upper strata, effectively air is carried out primary filter.Air gets into secondary filter 2 through primary filter 1 back by gas-entered passageway 3, carries out fine filtering, gets into diesel engine by connection mouth 21 again, gets the grains of sand and dust in the effective filtered air of whole device.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
