Technical field
The invention belongs to turbo-charger technical field, arbitrarily downgrade booster more particularly, to a kind of Two Stage Turbocharging System height
Support construction.
Background technology
Turbocharger is to improve engine charge density using the energy of engine discharge exhaust gas, since supercharging is started
The characteristics of high power of machine, low oil consumption, low emission, on the engine using quite extensively.Two Stage Turbocharging System is to adapt at present
Maximum discharge requirement, the gas system scheme of small-sized high-power output engine, can using the boost pressure after two-stage supercharging
It increasing substantially, each independent plenums device can be operated in the working region of greater efficiency, when two boosters work, hair
Motivation range of flow is widened significantly, and the raising of high pressure ratio operating mode boost pressure is that single stage supercharging is unapproachable, can be met very well
Diesel engine improves power and meets the needs of discharge.
But two-stage supercharging is the working method of two boosters, and system bulk weight can increase.Especially two superchargings
The installation fixed form of device on the engine is compared with the increasingly complex difficulty of single-stage supercharger.Hiigh pressure stage booster is smaller, can be by sending out
Motivation exhaust pipe supports, and fixed exhaust connection, low-pressure stage whirlpool are needed between lower pressure stage turbine case and hiigh pressure stage turbine box
After roller box import is fixedly connected with the outlet of hiigh pressure stage turbine box, in order to ensure that booster is solid and reliable, another branch is also needed
Support point.The center of gravity of booster is generally tended on turbine box, fixed supporting point is usually in addition looked on lower pressure stage turbine case, at this time such as
Fruit support is unreliable, it may appear that low-pressure stage booster cantilever vibration causes booster to connect unreliable failure and occurs, while low pressure
Grade turbine box import adds another hiigh pressure stage booster supporting point after being fixed with hiigh pressure stage turbine box outlet connection, it may appear that
Positioning scenarios are crossed, lead to the appearance of initial connection pretightning force.
Invention content
In view of this, the booster support construction the present invention is directed to propose a kind of Two Stage Turbocharging System height is arbitrarily downgraded, to realize
The compact reliability connection of secondary engine pressure charging system, while avoided the occurrence of positioning scenarios.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
A kind of Two Stage Turbocharging System height is arbitrarily downgraded booster support construction, and including hiigh pressure stage booster, hiigh pressure stage turbine goes out
Mouth smoke exhaust pipe, booster supporter and low-pressure stage booster；Hiigh pressure stage booster connects the exhaust pipe of engine；The booster branch
Support body one end is fixed on the engine, and the other end is by supporting connection low-pressure stage booster above hollow flange, connection is high below
It arbitrarily downgrades turbine outlet smoke exhaust pipe, the hollow space of flange is gas channel；The hiigh pressure stage turbine outlet smoke exhaust pipe is equipped with can
With the hose construction of adjustment length and angle.
Further, the booster supporter include engine end connector, low-pressure stage booster end connector and in
Between connector, the intermediate connecting body is broken line type, and one end is welded and fixed with engine end connector, the other end and low-pressure stage increasing
Depressor end connector is welded and fixed；The low-pressure stage booster end connector is hollow flange, is pressurized by screw and low-pressure stage
Device and hiigh pressure stage turbine outlet smoke exhaust pipe link together.
Further, the hiigh pressure stage turbine outlet smoke exhaust pipe is equipped with the bellows structure that can be adjusted.
Relative to the prior art, the present invention has the advantage that：
The present invention is applied to the installation support of secondary engine pressure charging system, in compactedness connection procedure, passes through a band
The booster supporter of hollow flange realizes that booster support of just arbitrarily downgrading is independent of each other, realizes secondary engine pressure charging system
Compact reliability connection；There is adjustable bellows design structure in two supports of hiigh pressure stage booster simultaneously, can keep away
Exempt to occur supporting positioning.

Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of present invention Two Stage Turbocharging System height is arbitrarily downgraded booster support construction, as shown in Figure 1, 2, is increased including hiigh pressure stage
Depressor 2, hiigh pressure stage turbine outlet smoke exhaust pipe 3, booster supporter 4 and low-pressure stage booster 5；The connection hair of hiigh pressure stage booster 2
Motivation exhaust pipe 1；Described 4 one end of booster supporter is fixed on the engine, and the other end passes through the company of support above hollow flange
Low-pressure stage booster 5 is connect, connects hiigh pressure stage turbine outlet smoke exhaust pipe 3 below, the hollow space of flange is gas channel；The height
