Abstract
The invention relates to a two-stage supercharging system structure. The two-stage supercharging system structure comprises a double-inlet flange (1), a high-pressure by-pass pipe (2), a high-pressure inlet pipe (3), a high-pressure outlet pipe (4), a high-pressure outlet flange (5), a low-pressure inlet flange (6), a low-pressure supercharger (7) and a high-pressure supercharger (8). The two-stage supercharging system structure is characterized in that one end of the high-pressure by-pass pipe (2) and one end of the high-pressure inlet pipe (3) are arranged on the double-inlet flange (1), the other end of the high-pressure by-pass pipe (2) is connected with the high-pressure outlet pipe (4), the other end of the high-pressure inlet pipe (3) is connected with the high-pressure supercharger (8), an outlet of the high-pressure outlet pipe (4) is the high-pressure outlet flange (5), and the high-pressure outlet flange (5) is connected with the low-pressure inlet flange (6) of the low-pressure supercharger (7). The two-stage supercharging system structure is compact, the number of parts can be decreased, and the high-temperature connection stability is improved.
Description
Technical field
The invention belongs to turbo-charger technical field, be specifically related to a kind of Two Stage Turbocharging System structural configuration.
Background technique
Under the dual-pressure increased the weight of in world oil resource exhaustion acceleration and environmental pollution, automobile and internal-combustion engine research institution all are being devoted to combustion engine energy-saving reduction of discharging new industrial research, supercharging technology, as the means of effective raising engine performance, is day by day paid attention to and is promoted.Strict along with national Abgasgesetz and energy-saving act, and engine power density further promotes demand, proposed the working method of two-stage supercharging.After adopting two-stage supercharging, the boost pressure that enters cylinder can be greatly improved than single stage supercharging, and each independent plenums device all can be operated in the working zone of greater efficiency, during the high pressure ratio operating mode, single supercharger speed relative reduce, the pressurized machine reliability is improved.After increasing the adjusting control structure in simultaneity factor, according to Under Different Work Condition of Engine, can between two pressurized machines, be regulated, the raising of low speed operating mode pressure ratio is that single stage supercharging is unapproachable, can finely meet the automobile-used full operating mode user demand of motor.But, with respect to single stage supercharging, Two Stage Turbocharging System exists the shortcomings such as controlling mechanism complexity, volume and weight increase, so two-step supercharging compact type light-weight design will become Focal point and difficult point.
Summary of the invention
Technical problem to be solved by this invention is by adopting the connecting tube Integrated design that will enter the turbine of just arbitrarily downgrading on the high pressure stage turbine box, reduced number of parts, having realized a kind of Two Stage Turbocharging System structural configuration of system compact type and lightweight design.
Technological scheme of the present invention: a kind of Two Stage Turbocharging System structural configuration, it comprises double feed inlet flange 1, high pressure bypass tube 2, high-pressure inlet pipe 3, high-pressure outlet pipe 4, high-pressure outlet flange 5, low pressure inlet flange 6, low-pressure turbocharger 7, high-voltage booster 8, an end that it is characterized in that described high pressure bypass tube 2 and high-pressure inlet pipe 3 is arranged on double feed inlet flange 1, the other end of high pressure bypass tube 2 is connected with high-pressure outlet pipe 4, the other end of high-pressure inlet pipe 3 is connected with high-voltage booster 8, the outlet of high-pressure outlet pipe 4 is high-pressure outlet flange 5, high-pressure outlet flange 5 is connected with the low pressure inlet flange 6 of low-pressure turbocharger 7.
Described high pressure bypass tube 2 and the integrated design of high-pressure outlet pipe 4.
Beneficial effect of the present invention: the present invention adopts integrated bypass pipe design on the high pressure stage turbine box, pass through Integrated design, can reduce amount of parts, the system architecture compactness, the high-temperature component connection part reduces, and can improve system architecture stability, invents simple in structure, good manufacturability, all bring income meeting aspect military requirement and part reliability.
The accompanying drawing explanation
Fig. 1 is high-voltage booster turbine box structural representation of the present invention;
Fig. 2 is Two Stage Turbocharging System structural configuration schematic diagram of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, a kind of Two Stage Turbocharging System structural configuration, comprise high pressure double feed inlet flange 1, high pressure bypass tube 2, high-pressure outlet pipe 4, high-pressure outlet flange 5, low pressure inlet flange 6, low-pressure turbocharger 7, high-voltage booster 8, an engine exhaust part enters high-voltage booster 8 by high pressure stage turbine box double feed inlet flange 1, by high-pressure outlet pipe 4, enter low pressure inlet flange 6; Part engine exhaust enters high low pressure bypass tube 2 by another import of double feed inlet flange 1, without high pressure stage supercharging 8, directly enters low pressure inlet flange 6, and then two-part exhaust enters low-pressure turbocharger 7 actings jointly.
The present invention together with high pressure bypass tube 2 Integrated designs, introduces respectively by engine exhaust the turbine of just arbitrarily downgrading by high pressure double feed inlet flange 1 by high-voltaghe compartment outer pipe 4.High pressure bypass tube 2 and the integrated design of high-pressure outlet pipe 4, connect compactness, can reduce amount of parts, increases high temperature conjunction stability.
