Abstract
The utility model discloses an air inlet channel of a supercharger. The air inlet channel comprises an arc with the radius R1 and an arc with the radius R2, and is formed by smoothly connecting the arc with the radius R1 with the arc with the radius R2. D0 is required to be selected according to different flow rates. Sizes of all components of the air inlet channel have relations as follows: D1/D0 is equal to 1.01 to 1.05, D2/D0 is equal to 1.3 to 1.5, h/D0 is equal to 0.05 to 0.1, and H/D0 is equal to 0.25 to 0.35. Compared with the air inlet channel of the supercharger in the prior art, the air inlet channel is characterized that air in the air inlet channel is smoother under the same conditions, impact loss at the inlet of a compressor impeller is reduced, and the static pressure is improved by about 20 percent.
Description
Technical field
The utility model relates to a kind of pressurized machine free-air diffuser.
Background technique
Existing supercharger air compressor partly partly is made up of air inlet pipeline, compressor impeller, Diffuser, spiral case etc., and wherein compressor impeller and Diffuser are the critical components of pressurized machine.But along with the continuous development of pressurized machine technology, more and more higher to the pressure ratio and the efficient requirement of pressurized machine, need deepen research to the aerodynamic characteristic of each parts, the research of air inlet pipeline just belongs to wherein one.At present, the circular arc that the pressurized machine free-air diffuser is R by one section radius becomes the line segment at A degree angle to form with one section, this relatively simple for structure, easy to process, and the stagnation pressure efficient of existing pressurized machine is about 60%.Its shortcoming is that air-flow is bigger to the impact loss of pressurized machine free-air diffuser and compressor impeller inlet, and static pressure is lower.
The model utility content
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of novel gas flow pressurized machine free-air diffuser more smoothly is provided.
The technical solution of the utility model is: this pressurized machine free-air diffuser, and it comprises that radius is that circular arc and the radius of R1 is the circular arc of R2, free-air diffuser is to be that the circular arc of R1 and circular arc smooth connection that radius is R2 form by radius.Select D0 according to different traffic requirements.There are following relation: D1/D0=1.01～1.05 between each size of intake duct, D2/D0=1.3～1.5, h/D0=0.05～0.1, H/D0=0.25～0.35.In the formula: D0 is a throat diameter; D1 is the runner exit diameter; D2 is the runner inlet diameter; H is the runner total height; H is the aditus laryngis height.
The utility model is compared with pressurized machine free-air diffuser of the prior art has following characteristics: under the same conditions, the gas flow of pressurized machine free-air diffuser of the present utility model is more smooth and easy, impact loss in compressor impeller inlet reduces, and static pressure improves about 20%.

Fig. 1 is a pressurized machine free-air diffuser structural representation of the prior art.
Fig. 2 is a pressurized machine free-air diffuser structural representation of the present utility model.
Embodiment
Now in conjunction with the accompanying drawings the utility model is further specified: Fig. 1 is the structural representation of pressurized machine free-air diffuser of the prior art, and the circular arc that the pressurized machine free-air diffuser is R by one section radius becomes the line segment at A degree angle to form with one section.Fig. 2 is a pressurized machine free-air diffuser structural representation of the present utility model, and it comprises that radius is that circular arc and the radius of R1 is the circular arc of R2, smooth connection between them.Select D0 according to different traffic requirements, have following relation: D1/D0=1.01～1.05 between each size of intake duct, D2/D0=1.3～1.5, h/D0=0.05～0.1, H/D0=0.25～0.35.
Should be noted that at last: though abovely described embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; can make numerous variations or modification to these embodiments; and not deviating from principle of the present invention and essence, protection domain of the present utility model is defined by the claims.
