Problems solved by technology

Since the outer surface of the hub of the above-mentioned impeller system is a streamlined and smooth surface, when the impeller does work on the intake air, the gas enters the meridional channel of the impeller at high speed. Because the pressure, temperature and speed of the gas are very uneven, and at the same time, the air flow in the channel of the blade and the hub The wall surface is adhesive. In the smooth meridian channel, the gas is prone to turbulence and eddy current, which cannot flow smoothly in the ideal direction, resulting in collision and friction between the gases, thereby increasing the gas temperature and reducing the efficiency of the impeller.

Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, the high-efficiency compressor impeller of the present invention includes a hub, and the hub includes an axle 2, and a bottom plate 4 is fixed at the inner end of the axle 2. The base plate 4 is circular, and its plate surface is perpendicular to the wheel shaft, and the outer surface of the wheel shaft 2 and the plate surface of the base plate 4 are smooth surfaces, so that the hub is in the radial direction from the axial direction of the wheel shaft 2 to the base plate 4. Streamlined horn shape with excessive arc. Blades 1 are evenly distributed in the circumferential direction of the hub, and the blades are helical. Flow guide grooves 3 are processed on the hub between adjacent blades 1, and the flow guide grooves 3 are evenly arranged on the hub along the streamline direction. When the gas enters the meridian channel between two adjacent blades 1, the turbulence and eddy current generated by the gas can be eliminated thro...

Abstract

The invention relates to an efficient gas compressor vane wheel, in particular to a gas compressor vane wheel on a turbocharger. The vane wheel comprises hubs, the hubs are of an axial-to-radial streamline-typed arc-turning trumpet shape, and blades are evenly distributed outside the hubs. The gas compressor vane wheel is characterized in that each hub arranged between two adjacent blades is provided with one diversion trench, and the diversion trenches are distributed in a streamline direction on each vane wheel. With the efficient gas compressor vane wheel, collision and friction between gases can be reduced, gas temperature can be reduced and efficiency of the vane wheel can be improved. The efficient gas compressor vane wheel is applicable to superchargers with high-pressure ratio and high-efficiency.

Description

technical field [0001] The invention relates to a turbocharger. Specifically, it is the compressor wheel on the turbocharger, especially suitable for high-pressure ratio, high-efficiency superchargers. Background technique [0002] Everyone in the internal combustion engine manufacturing industry knows that the supercharger is the second milestone in the history of internal combustion engine manufacturing. As an important part of the internal combustion engine, the supercharger can increase the power of the internal combustion engine, reduce the emission of harmful gases, and at the same time make the emission of the internal combustion engine meet the international emission standards and meet the purpose of environmental protection. [0003] At present, the most popular supercharger is a dumbbell type, which includes three parts: turbine end, compressor end and intermediate body. As the core part, the rotor is supported by the middle bearing seat, which plays an important...
