Description
Technical field
The utility model belongs to booster technical field, is related to a kind of closed supercharger air compressor leaf of air inlet blade face
Wheel.
Background technology
Booster should refer to air-admission pressure-booster for engine, including three kinds of forms：Exhaust-driven turbo-charger exhaust-gas turbo charger, mechanical turbine supercharging
Device, electric auxiliary turbine pressurizer.By compressed air, the density of the induced air of engine is improved, is started so as to improve
The power per liter of machine.Simultaneously because the mixed combustion regulation of engine is improved, efficiency of combustion is improved, section can also be played
Save fuel oil and reduce the effect of discharge.It is an important technological progress of Modern Engine.
Compressor impeller is the important composition part of booster, and the quality of gas compressor blade wheel construction has to the power of booster
There is considerable influence.Existing compressor impeller is usually a single piece, is directly mounted in pressure shell during use, at work, one
Partial air is missed, and does not have pressurization, causes the power of booster relatively low.
The content of the invention
The utility model is in view of the above-mentioned problems, provide a kind of closed pressure booster blower impeller of air inlet blade face, the leaf
Wheel can effectively reduce gas leak phenomenon, improve the operating efficiency of booster.
According to the technical solution of the utility model：A kind of closed pressure booster blower impeller of air inlet blade face, its feature
It is：Including impeller body, the outer meridian plane of blade of the impeller body is provided with wind scooper, the inner surface contour and impeller of wind scooper
The blade outline of body is matched, and gas outlet is formed between the lower end and impeller bottom surface of wind scooper.
As further improvement of the utility model, the wind scooper is axially extended to the short blade upper end of impeller body
Opening position.
As further improvement of the utility model, the wind scooper is axially extended to the linear leaf upper end of impeller body
Opening position.
As further improvement of the utility model, the centre of gyration of the impeller body is provided through being used for rotary shaft
The through hole of installation.
It is of the present utility model to have technical effect that：The utility model product structure advantages of simple, by for existing supercharging
Device carries out specific aim improvement the problem of existing operating efficiency is relatively low in the course of the work, and wind-guiding is equipped with impeller body
Cover, avoids air from missing by wind scooper, density of the induced air is improved, so as to improve the pressurization of booster.

Embodiment
Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings.
In Fig. 1 ~ 6, including impeller body 1, wind scooper 2, pressure shell 3, through hole 4, impeller bottom surface 5, gas outlet 6, pressure shell diffusion
Face 7 etc..
Fig. 1 ~ 3 show the first embodiment of the present utility model：A kind of closed booster of air inlet blade face is calmed the anger
Machine impeller, including impeller body 1, the outer meridian plane of blade of impeller body 1 are provided with wind scooper 2, the inner surface contour and leaf of wind scooper 2
The blade outline of wheel body 1 is matched, and gas outlet 6 is formed between the lower end and impeller bottom surface 5 of wind scooper 2, and wind scooper 2 is along axle
To extending at the linear leaf upper end position of impeller body 1.In this kind of scheme, wind scooper 2 is helped to the blade-shaped of impeller body 1
Enclosed construction, at work, gas leak phenomenon can be effectively reduced, improve air utilization ratio, and then improve the power of booster.Such as
Shown in Fig. 3, this kind of scheme when in use, is engaged with the pressure shell 3 of particular design, and the upper end of wind scooper 2 is placed in the step position of pressure shell 3
Place is put, pressure shell diffusion face 7 of the lower end of wind scooper 2 substantially with pressure shell 3 is in same plane, impeller gas outlet 6 and the phase of pressure shell diffusion face 7
Coordinate, improve the intake efficiency of air.
Fig. 4 ~ 6 show second of embodiment of the present utility model, and the difference with the first embodiment is：Wind-guiding
Cover 2 is axially extended to the short blade upper end position of impeller body 1, forms semi-closed structure.
The centre of gyration of the impeller body 1 of two kinds of embodiments is provided through the through hole 4 for rotary shaft installation.Figure
6 be the use state diagram of second of embodiment, and the upper end of wind scooper 2 is placed in below the step surface of the pressure shell 3 to match, led
The lower end of fan housing 2 is substantially engaged with pressure shell diffusion face 7, carried in same plane, impeller gas outlet 6 with the pressure shell diffusion face 7 of pressure shell 3
The intake efficiency of high air.
