Description
(1) technical field
The utility model relates to a kind of new-type air cleaner inlet structure, belongs to motor car engine air purifying process field.
(2) background technique
Along with China's emission standard enters state's IV stage, the quality of filter cleaner product also needs corresponding raising, and in view of the current reason such as fuel qualities and air quality of China, the performance boost of filter cleaner product is most important to realizing of emission standard upgrading.
Air-strainer is the vitals of engine aspirating system, effect is to provide clean, dry air to motor, reduce the wearing and tearing of cylinder, piston and piston ring etc., promote burning, it has direct impact to engine power performance, Economy, and heavy-duty car severe at environment and that travel in the poor area of maintenance condition can be selected oil bath/dry type combination air-strainer mostly at present.
The main performance of air-strainer is filtering efficiency and intake resistance, but the two is conflicting, wants to ensure lower intake resistance, will inevitably make filtering efficiency reduce; And to keep high filtering efficiency, and can produce larger intake resistance, in addition, the existence of intake resistance/pressure loss can cause larger energy loss, thereby affects the performance of motor.
The pressure loss comprises two types: the first is local pressure loss, mainly because the variation (as elbow) of flow section variation (comprising section shrinkage and expansion) or flow direction causes, thereby make that fluid clashes into, separation, whirlpool etc. phenomenon, produce resistance, cause energy loss; The second is along stroke pressure loss, is mainly the energy loss that in process fluid flow, the effect due to internal friction produces.
In addition, heavy truck will be realized high-power output, must increase air inflow, therefore, a lot of heavy trucks are now just generally larger with the volume of air-strainer, find by analysis, the design of filter cleaner product structure does not take into full account fluid flow characteristics, just do not research and develop from whole height design in order to realize a certain function, thereby cause the many structural designs of interiors of products unreasonable, produce larger intake resistance, cause very large energy loss, make motor overall performance can not get effective raising, when serious, even can affect its working life.
(3) summary of the invention
The utility model, in order to make up the defect of prior art, provides under a kind of guarantee filtering efficiency prerequisite, can effectively reduce intake resistance, more meet the new-type air cleaner inlet structure for heavy truck of fluid flow characteristics etc.
The utility model is achieved by the following technical solution:
A kind of new-type air cleaner inlet structure, include notch portion and strainer, intake section and strainer are arranged in same housing, it is characterized in that: described intake section comprises air inlet entrance, circular admission line, arc admission line and air inlet grid, air inlet grid is that integral type is connected with the housing of strainer, and installs floor additional at downside; Described strainer comprises oil sump and Steel net, the upper termination secondary filter of strainer outlet.
Wherein:
Described circular admission line and the turning of strainer are 45 degree, thereby the external structure of intake section meets fluid flow characteristics more, reach import and impact little object.
Described air inlet grid upside all adopts chamfering structure, when fluid reduces vibrations and noise in the time producing intense impact when near zone by air inlet grid below circular admission line.
Described arc admission line is away from all tangent with arc and the circular admission line of pressing close to strainer one side, thereby avoid fluid can produce intense impact in air cleaner inlet part corner, the generation that can produce the phenomenons such as eddy current near basin entrance.
Under described air inlet grid, plane adopts embedded layout around, and seals by seal ring, on the one hand can sealing air, prevent air return; Also alleviate on the other hand own wt.
Between described strainer and housing, add rubber seal, be penetrated with six through holes, and be bolted between strainer and housing, the weight that makes frame bear intake section and strainer, ensures that it normally works.
The utility model is designed to intake section after arc pipe, more meets the flow characteristic of fluid, can greatly reduce intake resistance, has reduced local energy loss, and inlet outlet pressure differential is farthest reduced.
The beneficial effects of the utility model are: simple in structure, easy to use; Ensureing under filtering efficiency prerequisite, can effectively reduce intake resistance, more meet fluid flow characteristics; Cost is low, easy to utilize.
(4) brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is strainer inner casing and housing equipment schematic diagram.
In figure: 1, air inlet entrance; 2, circular admission line; 3, arc admission line; 4, air inlet grid; 5, strainer; 6, floor; 7, oil sump; 8, Steel net; 9, rubber seal; 10, through hole.
Embodiment
Accompanying drawing is specific embodiment of the utility model.
The new-type air cleaner inlet structure of the utility model as depicted in figs. 1 and 2, include notch portion and strainer 5, intake section and strainer 5 are arranged in same housing, described intake section comprises air inlet entrance 1, circular admission line 2, arc admission line 3 and air inlet grid 4, air inlet grid 4 is that integral type is connected with the housing of strainer 5, and installs floor 6 additional at downside; Described strainer 5 comprises oil sump 7 and Steel net 8, the upper termination secondary filter of strainer 5 outlet, air inlet grid 4 upsides all adopt chamfering structure, when fluid reduces vibrations and noise in the time producing intense impact when near zone by air inlet grid 4 below circular admission line 2.
Under air inlet grid 4, plane adopts embedded layout around, and seals by seal ring, on the one hand can sealing air, prevent air return; Also alleviate on the other hand own wt; Between strainer 5 and housing, add rubber seal 9, be penetrated with six through holes 10, and be bolted between strainer 5 and housing, the weight that makes frame bear intake section and strainer 5, ensures that it normally works.
