Abstract
The utility model relates to a supercharger volute. A tail gas port and an air inlet are arranged on a shell; and the internal chamber of the shell is internally provided with an annular air flue that is communicated with the tail gas port. The supercharger volute is characterized in that the annular gap is arranged on the side wall at the internal side of the air flue; the external side of the annular gap is communicated with the air flue of the annular gap; and the internal side of the annular gap is communicated with the air inlet. The supercharger volute can realize influx air in 360 degrees, has high air introduction efficiency, and is beneficial to improving the working efficiency.
Description
Technical field
The utility model relates to a kind of pressurized machine volute.
Technical background
At present, the diesel pressure booster on the market utilizes motor exhaust to promote the turbine rotation, enters motor thereby promote pressurized air, to reach the raising fuel availability, promotes the purpose of engine power.Be provided with the air flue of annular in the volute of this pressurized machine, the outer end of air flue is connected to the motor exhaust interface, the inner of air flue is an annular, and wherein 180 degree spaces are sealed, with the suction port sealing of pressurized machine, other 180 degree space openings, be communicated with the suction port of pressurized machine, the benefit of doing like this is to improve the structural strength of volute, but has also just reduced the area in tail gas outlet port simultaneously, can only 180 the degree air inlets, influence the performance of efficiency of turbocharger.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, pressurized machine volute that efficient is high.
For achieving the above object, the utility model adopts following technological scheme:
Pressurized machine volute described in the utility model, comprise housing, housing is provided with tail gas interface and suction port, be provided with looped duct in the inner chamber of housing, described air channel is communicated with the tail gas interface, it is characterized in that: have annular breach on the sidewall of inboard, described air channel, the outside of described annular breach is communicated with the air channel, and the inboard of annular breach is communicated with suction port.
Described air channel and annular breach have two groups, are set in parallel on the axial direction of suction port.
Adopt after the technique scheme, this pressurized machine volute can be realized 360 degree air inlets, and the intake efficiency height helps improving the working efficiency of pressurized machine.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
As shown in drawings, pressurized machine volute described in the utility model, comprise housing 1, housing 1 is provided with tail gas interface 2 and suction port 3, be provided with looped duct 4 in the inner chamber of housing 1, described air channel 4 is communicated with tail gas interface 2, has annular breach 5 on the sidewall of 4 inboards, described air channel, the outside of described annular breach 5 is communicated with air channel 4, and the inboard of annular breach 5 is communicated with suction port 3.
During use, waste pipe is connected on the tail gas interface 2 by flange plate, the tail gas that motor is discharged enters air channel 4 by tail gas interface 2, blow the turbine rotation that is positioned at suction port 3 axis places by annular breach 5, by suction port 3 suck air, compression enters engine chamber in the time of the turbine rotation.Because the existence of annular breach 5, this pressurized machine volute have realized 360 degree air inlets, improved the utilization ratio of motor exhaust, can realize bigger efficient with littler volume.
In addition, described air channel 4 and annular breach 5 can be provided with two groups, are set in parallel on the axial direction of suction port 3, and two pipelines are set on the tail gas interface 2, respectively two exhaust ducts of corresponding motor.
