When air enters air inlet, the flow is guided through the swirl vane, the flow type of the air changes into that the air rotarily flow around the outer wall of the filter element, so that the pressure distribution and speed distribution on the surface of the filter element are very even, the performance of the air cleaner can be more stable and the filter element can be fully used.
Description
Technical field
The utility model relates to the air-strainer using on a kind of motor.
Background technique
Air-strainer is a vitals of engine aspirating system, and it is for the normal work that guarantees motor, and the working life that extends motor is significant.Motor will suck a large amount of air in the course of the work, if air is without filtering, the dust suspending in air is inhaled in cylinder, will accelerating piston group and the premature wear of cylinder wall, valve and valve seat, if enter in the lubrication system of motor, can cause the wearing and tearing at each pivot friction position, when serious, can cause pull-cylinder phenomena, this is especially serious in the working environment of dry sand and dust, and air-strainer also has the effect of subduing induction noise in addition.Its structure of current air-strainer is comparatively complicated, and the installing space needing is larger, is generally all arranged on top or the side of motor, and rainhat need to be installed in top, and need to the grey grit separating be introduced to relief opening by the injection power of silencing apparatus.Need to arrange long connecting pipeline simultaneously, not only waste material but also need large installing space, and the utilization of filter core is also abundant not.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of compact structure, the air-strainer of good filtration effect.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of air-strainer, comprise housing, in described housing, be coaxially arranged with filter core, one end of described housing is provided with air outlet, described air outlet is communicated with the inner chamber of described filter core, the other end of described housing is connected with end cap, described end cap is provided with annular air scoop, the end radial seal of described end cap and described filter core, described suction port is communicated with the gap between described housing and filter core, in the suction port of described end cap, be provided with the swirl vane of guiding air-flow along described filter core periphery rotational flow, described swirl vane evenly arranges along circumferential in suction port, described housing is provided with dust exhaust port near air outlet place.
Improve as one, described end cap and described housing removably connect.
Improve as one, described end cap is connected by snap ring with described housing.
Improve as one, described housing adopts PP-GF30 to strengthen nylon material and makes.
Improve as one, described end cap adopts PU material to make.
Improve as one, described housing is provided with the assembly department for being connected with motor, and described assembly department is provided with mounting hole.
Improve as one, described housing comprises the first portion and the second portion that are detachably installed together, described first portion is connected around described filter core and with described end cap, and described assembly department is arranged in described first portion, and described air outlet and dust exhaust port are arranged on second portion.
Owing to having adopted technique scheme, air will pass through swirl vane before entering the gap of housing and filter core, guiding through swirl vane to air-flow, the type of flow of air becomes the outer wall rotational flow around filter core, the centrifugal force of rotation is thrown to the impurity such as airborne dust on the wall of housing, finally discharge from dust exhaust port, air after filtration enters turbosupercharger through air outlet, by the effect of swirl vane, make gas uniform be wound in filter core periphery, make pressure distribution and the velocity distribution of cartridge surface very even, thereby make the performance of air-strainer comparatively stable, filter core utilization is abundant.And this product is simple and compact for structure, the installing space needing is little, can adopt air outlet upper, suction port under mode be installed in turbosupercharger, thereby simplification connecting pipeline, reduce installing space, guarantee that diesel engine is neatly smooth and easy into and out of pipeline, facilitate the installation of motor miscellaneous part.
Because end cap and described housing removably connect, can be easily renew cartridge more.
End cap is fixedly connected with by snap ring with described housing, simple in structure, easy accessibility.
Due to housing use PP-GF30 strengthen nylon make air filter weight gentlier, firmer, more attractive in appearance, and suitable environment temperature range is more extensive.
Because described housing is provided with assembly department, described assembly department is provided with mounting hole, just housing and motor can be linked together, thereby air filter position is fixed by bolt.Simple in structure, easy to use, take up room little.
The first portion and the second portion that are divided into detachable installation due to described housing form, and can reduce the manufacture difficulty of housing.
