Abstract
The utility model relates to a vaneless diffuser turbocharger air compressor volute, which comprises a volute body (1) and a volute body inner liner (14). An air inlet pipe (11) is arranged in the air compressor volute body (1). The volute body inner liner (14) is fixed in the volute body (1) through screws. The shape of the inner wall of the volute body inner liner (14) is adaptive to the shape of an air compressor impeller (2). The peripheral shape of the volute body inner liner (14) is adaptive to the shape of the inner wall of the volute body (1). Since the split-type air compressor volute is adopted, the utility model has the advantages that the installation is convenient and simple, and the difficulties in maintenance and machining are reduced.
Description
Technical field
The utility model relates to a kind of turbocharger air compressor, particularly a kind of no blade to enlarge pressure pipe turbocharger air compressor spiral case.
Background technique
Present turbosupercharger, small sized turbine pressurized machine particularly, generally be equipped with no blade to enlarge pressure pipe, no leaf formula diffuser pipe simple structure, working conditions change is very little to the influence of compressor efficiency, be particularly suitable for vehicle supercharger, no blade to enlarge pressure pipe is actually the air-flow path that is formed by compressor volute and intermediate sidewall.
Existing no blade to enlarge pressure pipe turbocharger arrangement as shown in Figure 2, its gas compressor comprises compressor volute 1 and compressor impeller 2; Be provided with intake duct 11 in the compressor volute 1, compressor volute 1 and intermediate sidewall form no blade to enlarge pressure pipe 12; The working principle of gas compressor is: when compressor impeller 2 rotations, air enters compressor impeller 2 through intake duct 11, and flows to the periphery of compressor impeller 2 under action of centrifugal force from compressor impeller 2 centers along the runner that forms between the curved surface inwall 13 of compressor impeller 2 blades and compressor volute 1; Air obtains energy from the compressor impeller 2 of rotation, its flow velocity, pressure and temperature all have bigger increasing, enter no blade to enlarge pressure pipe 12 then, no blade to enlarge pressure pipe 12 is the gradually expanding shape runner, deceleration supercharging when air flows through no blade to enlarge pressure pipe 12, temperature also raises to some extent, and promptly in no blade to enlarge pressure pipe 12, most of kinetic energy that air had changes the pressure energy into.During making, the curved surface inwall 13 of compressor volute 1 is mach emphasis difficulty, because the curved surface inwall 13 of compressor volute 1 complex-shaped is difficult for machining; And the damage of gas compressor mainly appears on the curved surface inwall 13 of compressor volute 1, so in compressor volute 1 maintenance, maintenance and maintenance are all very difficult, often need to change whole compressor volute 1, cause very big waste.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of no blade to enlarge pressure pipe turbocharger air compressor spiral case is provided, its maintenance and easy maintenance and need not integral replacing.
The technical solution of the utility model is: a kind of no blade to enlarge pressure pipe turbocharger air compressor spiral case, and it comprises volute body and volute body inside lining sleeve, is provided with intake duct in the compressor volute; The volute body inside lining sleeve is fixedly mounted in the volute body.
The further technological scheme of the utility model is: the inner wall shape of described volute body inside lining sleeve and the shape of compressor impeller adapt.
The utility model further technological scheme is: the peripheral shape of described volute body inside lining sleeve and volute body inner wall shape adapt.
The volute body inside lining sleeve is to be installed in the volute body by screw.
The utility model compared with prior art has following characteristics:
The split type compressor volute of a kind of employing of the utility model, easy for installation simple, can reduce the difficulty that maintenance and machine add, can adjust the convergent angle and the size of Diffuser by changing different volute body inside lining sleeves simultaneously.
Below in conjunction with the drawings and specific embodiments detailed structure of the present utility model is further described.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of existing no blade to enlarge pressure pipe turbosupercharger.
Embodiment
Embodiment
As shown in Figure 1: a kind of no blade to enlarge pressure pipe turbocharger air compressor spiral case, it comprises volute body 1 and volute body inside lining sleeve 14, is provided with intake duct 11 in the compressor volute 1, compressor volute 1 and intermediate sidewall form no blade to enlarge pressure pipe 12; The peripheral shape of volute body inside lining sleeve 14 and volute body 1 inner wall shape adapt, and the shape of the inner wall shape of volute body inside lining sleeve 14 and compressor impeller 2 adapts, and volute body inside lining sleeve 14 is fixed in the volute body 1 by screw 15.
The utility model is not limited to above-mentioned concrete structure, just drops within the protection domain of the present utility model so long as be provided with the turbocharger air compressor spiral case of volute body inside lining sleeve 14 that can dismounting in volute body 1.
