Abstract
The invention relates to a gas compressor impeller, which comprises a wheel disc, wherein the wheel disc is a circular disc, a shaft hole is formed in the center of the wheel disc, the center of one side of the wheel disc is provided with a shaft sleeve, the inner diameter of the shaft sleeve is identical to and corresponds to the diameter of the shaft hole formed in the wheel disc, the appearance of the shaft sleeve is in a horn shape, one end of a horn mouth of the shaft sleeve forms a whole with the wheel disc, and blades are uniformly distributed around the shaft sleeve. The gas compressor impeller is characterized in that the blades arranged on the end, far away from the wheel disc, of the shaft sleeve are arranged in a one-long-blade and one-short-blade alternate way, so that in the adjacent blades, one impeller is the long impeller, and the other impeller is the short impeller. When the gas compressor impeller is adopted, the fuel oil consumption can be reduced, and the occurrence of an overheat phenomenon of an engine is voided. The gas compressor impeller is applicable to an automobile engine supercharger.
Description
Technical field
The present invention relates to a kind of impeller.Specifically, be compressor impeller in turbosupercharger.Be applicable in motor car engine.
Background technique
All know at automobile manufacturing field, pressurized machine installed by the exhaust duct of motor car engine, automobile power can be improved, reduce fuel consume, reduce motor vehicle exhaust emission and pollution of atmosphere.Therefore, adopt by numerous automaker.At present, the compressor impeller that automobile booster uses is all conventional impellers, and this conventional impellers contains wheel disc, and described wheel disc is disk, and its center is processed with axis hole, and its one side center is provided with axle sleeve.Described sleeve diameter is equal with the axis hole on wheel disc and corresponding.The profile of described axle sleeve is tubaeform, makes its one end diameter be greater than the other end.Large end and the described wheel disc of axle sleeve form as one, and axle sleeve surrounding is evenly equipped with blade.The length of described blade and width are all equal.Because the length of blade is all equal with width, in the one end near pressurized machine suction port, this end flow area of blade reduces and can bring certain obstruction to the gas flow entering pressurized machine, thus decrease the air inflow of pressurized machine, make pressurized machine when running up, deficiency of air, causes fuel consume to increase, and motor is occurred overheated.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of compressor impeller.Adopt this compressor impeller, can fuel consume be reduced, avoid engine overheat phenomenon to occur.
The problems referred to above that the present invention will solve are realized by following technological scheme:
Compressor impeller of the present invention comprises wheel disc, and described wheel disc is disk, and there is axis hole at its center, and there is axle sleeve at its one side center; Described sleeve diameter is equal with the axis hole on wheel disc and corresponding; The profile of described axle sleeve is tubaeform, and its horn mouth one end and described wheel disc form as one; Axle sleeve surrounding is evenly equipped with blade, and be characterized in that away from the length of blade on that one end of axle sleeve of wheel disc be the alternate layout of long one end shape length, make in adjacent blades, an impeller is the wheel that comes into leaves, and another impeller is short impeller.
Wherein, away from the inside indentation in short blade one end of wheel disc, and indentation length is approximately 1/5 of vane overall length.
Described linear leaf and short blade are all greater than six.
Described linear leaf and short blade are seven.
Take such scheme, have the following advantages:
As can be seen from the above scheme, owing to being the alternate layout of long one end shape length away from the length of blade on that one end of axle sleeve of wheel disc, the blade quantity of supercharger air compressor suction port one end reduces half, make the gas flow entering pressurized machine smooth and easy, there will not be obstruction, thus add the air inflow of pressurized machine, make pressurized machine when running up, air inflow is sufficient, decreases fuel consume, avoids the generation of engine overheat phenomenon.
Accompanying drawing explanation
Fig. 1 is compressor impeller structural representation of the present invention;
Fig. 2 is compressor impeller schematic perspective view of the present invention.
Embodiment
As depicted in figs. 1 and 2, compressor impeller of the present invention comprises wheel disc 1, and described wheel disc 1 is disk, and its center is processed with axis hole 5, and its one side center is provided with axle sleeve 4.Described axle sleeve 4 internal diameter is equal with the axis hole on wheel disc 1 and corresponding.The profile of described axle sleeve 4 is tubaeform, makes its one end diameter be greater than its other end.The large end of axle sleeve 4 and described wheel disc 1 are cast into one.Axle sleeve 4 surrounding is evenly equipped with blade, is cast into one between blade and axle sleeve 4 surrounding.Away from the inside indentation in short blade 3 one end of wheel disc 1, and indentation length is 1/5 of vane overall length, and making away from the length of blade on that one end of axle sleeve 4 of wheel disc 1 is the alternate layout of long one end shape length, wherein, in adjacent blades, an impeller is the wheel that comes into leaves, and another impeller is short impeller.Described linear leaf 2 and short blade 3 are seven.Like this, the blade quantity of supercharger air compressor suction port one end decreases half, make the gas flow entering pressurized machine smooth and easy, there will not be obstruction, thus add the air inflow of pressurized machine, make pressurized machine when running up, air inflow is sufficient, decrease fuel consume, avoid the generation of engine overheat phenomenon.
