Abstract
The utility model relates to the supplementary structure that a kind of air filter system is filtered and flow resistance performance improves, be made up of deflector and central shaft, deflector is convex structure, be connected to the dirty air pipe outlets place of air filter system, central shaft is fed through deflector, is arranged in the air filter lower house at dirty air pipe outlets place of air filter system.Compared with prior art, the utility model can be used for because border restriction, the Way out of dirty air hose is caused inevitably to point in the air filter design of cartridge surface, significantly can not increase die cost, and the use amount of material, can effectively optimize cartridge surface velocity flow profile, optimize the strainability that lower house air flow method improves air filter, significantly reduce pitot loss.
Description
Technical field
The utility model relates to a kind of air filtration supplementary structure, especially relates to the supplementary structure that a kind of air filter system is filtered and flow resistance performance improves.
Background technology
Usually, air filter is all develop according to the boundary condition of OEM, in some cases, because the restriction of boundary condition, the Way out of dirty air hose inevitably points to cartridge surface, dirty air hose effluent air will be caused directly to have rushed at cartridge surface according to the design of such border air filter housing.Such design will cause cartridge surface flow velocity inequality extremely, and there is higher flow velocity in some regions of cartridge surface, and the strainability of air filter is relevant with air velocity.Too high flow velocity significantly can reduce the filtering accuracy of strainability and filter medium.If air velocity is too high, particle not easily adheres to fiber, and can rebound from fiber.In addition, the particle be blocked can be discharged (carrying effect secretly) again, and filter efficiency can reduce accordingly.Meanwhile, the air flowed out due to dirty air hose has directly flowed to filter core, causes velocity flow profile in air filter lower house uneven, and even air-flow can be back to lower house from filter core, makes air filter lower house pitot loss very big.
There are strict requirement in main engine plants to cartridge surface average speed and pitot loss, and often when this requirement cannot meet, both sides compromise separately, approve the design do not met the demands.In order to the design solved under this arbitrary boundary conditions makes cartridge surface average speed and pitot loss require implacable situation, this kind of structure is arisen at the historic moment.
Utility model content
The purpose of this utility model is exactly provide to overcome defect that above-mentioned prior art exists the supplementary structure that a kind of scope of application is wide, structure is simple, performance enhancing effects is given prominence to air filter system is filtered and flow resistance performance improves.
The purpose of this utility model can be achieved through the following technical solutions:
The supplementary structure that air filter system is filtered and flow resistance performance improves, is made up of deflector and central shaft,
Described deflector is convex structure, is connected to the dirty air pipe outlets place of air filter system,
Described central shaft is fed through deflector, is arranged in the air filter lower house at dirty air pipe outlets place of air filter system.
Described central shaft is flexibly connected with deflector.
Described deflector rotates around central shaft.
Described central shaft along deflector radially across deflector.
Described central shaft is located in the 1/4-1/3 place on deflector length direction.
Deflector can change dirty air pipe outlets airflow direction, avoid air-flow and directly rush at cartridge surface, optimize the air flow method of filter core and lower house, decrease the eddy current of lower house, by the axle be connected with air filter lower house, the angle that adjustable deflector rotates, compared with prior art, the utility model has the following advantages:
(1) scope of application is wide: can be used for because border restriction, causes the Way out of dirty air hose inevitably to point in the air filter design of cartridge surface;
(2) structure is simple: significantly can not increase die cost, and the use amount of material;
(3) performance enhancing effects is given prominence to: can effectively optimize cartridge surface velocity flow profile, optimizes the strainability that lower house air flow method improves air filter, significantly reduces pitot loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model structural representation in use.
In figure, 1-deflector, 2-central shaft, 3-air filter lower house.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
The supplementary structure that air filter system is filtered and flow resistance performance improves, its structure as shown in Figure 1, is made up of deflector 1 and central shaft 2, and be arranged on air filter lower house 3 place, its structure as shown in Figure 2.Deflector 1 is convex structure, and be connected to the dirty air pipe outlets place of air filter system, central shaft 2 is fed through deflector 1, is arranged in the air filter lower house 3 at dirty air pipe outlets place of air filter system.Central shaft 2 is flexibly connected with deflector 1, more particularly, central shaft 2 along deflector 1 radially across deflector 1, can be arranged on the 1/4-1/3 place on deflector 1 length direction, deflector 1 can rotate around central shaft 2 in use.
The utility model in use, rotatable deflector 1 is utilized to change dirty air pipe outlets airflow direction, avoid air-flow and directly rush at cartridge surface, optimize the air flow method of filter core and lower house, decrease the eddy current of lower house, by the convenient angle regulating deflector 1 to rotate of central shaft 2 be connected with air filter lower house, thus make range of application more extensive.
