Abstract
An arc-shaped oblique flow turbocharger compressor impeller comprises a hub, long blades and short blades. The number of the long blades and the number of the short blades both range from four to six and are identical. The long blades and the short blades are evenly distributed on the hub in a staggered mode. The tops of airflow outlets of the long blades and the tops of airflow outlets of the short blades are of an arc shape, wherein the blade tip of the arc-shaped sideline is higher than the blade root of the arc-shaped sideline, and the contour of the outer circle of the blade root of the arc-shaped sideline is consistent with the diameter of the outer circle of a wheel disc of the hub. According to the arc-shaped oblique flow turbocharger compressor impeller, the arc-shaped oblique flow outlets are used for relieving the condition that flow fields in the unfolding direction of the outlets of the impeller are distributed unevenly because the curvature of a rim of the impeller is too large, and the design parameter level of the impeller can be adjusted by adjusting the circular arc diameter of the sideline of the outlets of the impeller, so that the working efficiency of a compressor is improved.
Description
Technical field
The present invention relates to turbocharger for gasoline engine technical field, particularly a kind of turbocharger for gasoline engine compressor impeller.
Background technique
Turbocharging technology is the energy utilizing motor combustion gas, rotarily drive turbine wheel rotation by turbine and become mechanical work, the compressor impeller coaxial with turbine wheel also runs up with same speed, after compresses fresh air, send into cylinder, improve air density and the aeration quantity of cylinder, thus improve the power of motor, improve the combustion condition of fuel oil, make fuel oil Thorough combustion, thus fuel consume is reduced, decrease the ratio of harmful substance in the waste gas entering air, and then finally realize environmental protection and energy saving, improve the effect of engine power, play the effect recovering power when motor being worked on plateau simultaneously.
In recent years, petrol engine miniaturization has become a kind of development trend, and in order to improve the power per liter of motor, effective method is coupling exhaust-gas turbocharger the most.Low-speed performance focused on by petrol engine, and require that motor has low-speed big and good fuel-economy performance, this proposes more strict demand to booster performance.And the raising of compressor efficiency effectively can improve the performance of whole pressurized machine, impeller, as the core pneumatic element of gas compressor, plays a leading role to Capability of Compressor.Therefore, the design ap-plication of high-efficiency vane wheel has become inevitable.
At present, except design high-efficiency vane wheel blade profile improves except impeller adiabatic efficiency, on existing high-efficiency vane wheel blank basis, impeller performance also can be made further to be promoted by adjustment impeller size and impeller outlet structure.And for impeller outlet structural design, now widely used pressure booster blower impeller mainly adopts radial-flow impeller structure, traditional radial-flow impeller as shown in Figure 1, comprise wheel hub 1, plural pieces linear leaf 2 and plural pieces short blade 3, linear leaf 2 is the same with the quantity of short blade 3, linear leaf 2 and cross-shaped being evenly distributed on of short blade 3 are drawn together on wheel hub 1, the blade tip of linear leaf 2 flow outlet top 2-1 and short blade 3 flow outlet top 3-1 and blade root are on a horizontal line, and with the axis being parallel of wheel hub 1, the wheel disc outside diameter of wheel hub 1 is consistent with the excircle configuration diameter of footpath outflow opening.
Traditional radial-flow impeller Problems existing easily produces backflow in vaneless diffuser import wheel rim side under pressurized machine small flow.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and a kind of arc oblique flow turbo-charger blower impeller is provided.
Technological scheme of the present invention is: a kind of arc oblique flow turbo-charger blower impeller, comprise wheel hub, four ~ six linear leafs and four ~ six short blades, linear leaf is the same with the quantity of short blade, linear leaf and cross-shaped being evenly distributed on of short blade are drawn together on wheel hub, linear leaf flow outlet top and short blade flow outlet top are arc, the blade tip in arc sideline is higher than blade root, and the excircle configuration of blade root position, arc sideline is consistent with the wheel disc outside diameter of wheel hub.
Arc oblique flow turbo-charger blower impeller provided by the invention, the too large and impeller outlet exhibition that causes of wheel rim curvature is improved to the uneven state of Flow Field Distribution by the outlet of arc oblique flow, and the arc diameter that can export sideline by adjusting vane regulates the design parameter level of impeller, improves the working efficiency of gas compressor.
The present invention compared with prior art has following features:
1, the too large and impeller outlet exhibition that causes of wheel rim curvature is improved to the uneven state of Flow Field Distribution by the outlet of arc oblique flow, and the arc diameter that can export sideline by adjusting vane regulates the design parameter level of impeller, improves the working efficiency of gas compressor.
2, the impeller after improving, when pressurized machine assembles, only needs to revise a little pressurized machine back of the body dish adjacent with it, is convenient to produce, and reduces cost.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present invention is further described.
