Abstract
The utility model discloses an efficient mixed flow compressor impeller, comprising a hub main body and a plurality of blades combined with the hub main body, wherein the hub main body is fixed on a rotor axle, the blades are mixed flow blades, a flow path is formed between two adjacent blades, the distance between the outer edge of the blade to the center of the hub main body is larger than the radius of the hub main body, thus an auxiliary mixed flow part is formed on the outer edge of the blade, the efficient mixed flow compressor impeller uses the mixed flow blade, the distance between the outer edge of the blade to the center of the hub main body is larger than the radius of the hub main body, thus the compressor efficiency is obviously increased by about 4%, the structure is simple, the impeller is easy to produce and the structure reliability is high.
Description
Technical field
The utility model relates to a kind of efficient mixed flow compressor impeller.
Background technique
As everyone knows, the history of the existing last 100 years of internal combustion engine use supercharging technology, particularly in recent years along with the serious day by day situation of energy shortage, environmental pollution, supercharging technology has become a kind of essential technology that adopts in field of internal combustion engine.At present, a large amount of supercharging and charge inter cooling technology of adopting on China internal-combustion engine industry, particularly diesel engine are to satisfy the exhaust index and the energy conservation object in national each stage of releasing.
At present, the whirlpool pressurized machine that sinks is widely adopted on diesel engine, supercharging technology is ripe day by day, each research institute and universities and colleges are all endeavouring raising and are improving, the wherein most importantly application of the raising of efficient and new material, pressurized machine total efficiency have three parts to constitute: total efficiency η=turbine efficiency * mechanical efficiency * compressor efficiency.The raising of total efficiency can the more efficient use exhaust energy, give the high-quality combustion gas medium of gas engine high pressure low temperature, and the most important direction of approach that improves total efficiency provides the efficient of gas compressor, main target is to improve efficiency of turbocharger, two cores that impeller is a pressurized machine wherein, and turbine wheel has had mixed flow impeller, be widely used in external most of market and domestic fraction market, see also diagram, Fig. 1 is portion's dress sectional drawing of conventional impellers, conventional impellers comprises hub body 1a, the blade 1b that combines with body 1a, by the mounting hole on the described body 1a, locking nut 1d is fixed in whole impeller on the rotor shaft 1c, but the outer rim of the blade 1b of this kind impeller is alignd with the outer rim of body 1a, and leaf and processing characteristic has influenced compressor efficiency to this kind impeller because of it.
The model utility content
The purpose of this utility model is to provide a kind of efficient mixed flow compressor impeller, and it has simple in structure, and flow stream scope is wide, the characteristics that efficient height and structural reliability are high.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of efficient mixed flow compressor impeller, most blades that it comprises hub body and combines with hub body, described hub body is fixed on the rotor shaft, wherein, described blade is the mixed flow blade, form runner between adjacent two blades, and described blade outer rim makes the outer rim of blade form auxiliary mixed flow portion to the distance at the hub body center radius greater than hub body.
Offer center hole on the described hub body, whole mixed flow impeller is fixed on the rotor shaft with locking nut by center hole.
The beneficial effects of the utility model are, the blade of described efficient mixed flow compressor impeller adopts the mixed flow blade, and its outer rim arrives the radius of the distance at body center greater than body, makes the outer rim of blade form auxiliary mixed flow portion, has increased the mixed flow scope of impeller, efficient obviously improves 4%, not only simple in structure, be easy to realize, and the mixed flow scope is wide, mixed flow is effective, the structural reliability height.
