Fig. 1 is the structural representation provided in an embodiment of the present invention for being adapted to multi-model engine test gas extraction system.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
As shown in figure 1, multi-model engine test gas extraction system is adapted to the embodiments of the invention provide one kind, including it is only
Found joint module, standard module, silencer module, exhaust resistance adjustment module and take out fume extractor；Wherein, individual contacts module
One end be fixedly connected with engine, specifically, individual contacts module can be with enmgine exhaust or booster exhaust outlet
It is connected；One end of standard module is fixedly connected with one end away from engine in individual contacts module, the position for compensation system
Move and angular deviation；One end of silencer module is fixedly connected with one end away from individual contacts module on standard module；Exhaust
One end of resistance regulation module is fixedly connected with one end away from standard module in silencer module, exhaust resistance adjustment module
The other end is fixedly connected with taking out fume extractor.
In adaptation multi-model engine test gas extraction system provided in an embodiment of the present invention, individual contacts module is independent
Interface specification in the one end being connected in gas extraction system, and individual contacts module with engine can be according to enmgine exhaust
Or booster exhaust outlet interface specification and carry out compatibility design, thus achieve the gas extraction system and go for various machines
The engine of type.
It should be noted that individual contacts module can be designed with several specification, when testing different type of machines,
Only need to change corresponding individual contacts module, in the present embodiment, individual contacts module devises four kinds of specifications, so that
The test requirements document of various model engines at this stage can be met.
Can in the parameters such as pressure, temperature and oxygen concentration for the ease of measuring engine exhaust port, individual contacts module
To be set side by side with for installing pressure, temperature and the sensor mounting hole of lambda sensor.
Further, the length range value of individual contacts module is 240mm~350mm, so as to being each sensor
Between and sensor and exhaust side outlet between reserve enough distances, to ensure sensor to the detection of each parameter essence
Degree, further, since the delivery temperature in exhaust side exit can reach 950 DEG C, and individual contacts module is made up of metal,
Its tolerable temperature is up to 600 DEG C, therefore needs to install additional axial flow blower fixed point in exhaust side exit to the progress of individual contacts module
Brush, it at least needs 200mm length, just can guarantee that delivery temperature is down to less than 600 DEG C, therefore, individual contacts module it is total
Length can just ensure gas extraction system normal work in the range of 240mm~350mm.

Silencer, but if needing to use particular muffler component or combination in experiment, can be substituted in the present embodiment with particular elements
Silencer or reserved module is combined to arrange silencer combined system, to meet test requirements document.
Further, standard module includes automatic compensating module and system fading margin module, and automatic compensating module and system are adjusted
Section module is sequentially connected in series between engine and reserved module；Automatic compensating module and system fading margin module can use tubulose class
Structure, in the present embodiment, automatic compensating module are metal hose, and system fading margin module is carbon steel seamless steel pipe, wherein, preferably
, metal hose is spiral shape corrugated stainless steel tubing.Spiral corrugated stainless steel tubing comparatively, flexible and fatigue resistance
Can be more outstanding, preferably (600 DEG C of maximum temperature), the length of single tube is longer, reliability is higher for corrosion resistance, resistance to elevated temperatures.Spiral
The metal hose of shape easily absorbs the gas extraction system vibration deformation and cyclic loading, disclosure satisfy that whole system larger displacement and angle
The compensation of deviation.Carbon steel seamless steel pipe is hard tube, and the gas extraction system can be caused to be limited according to actual needs with place
Any adjustment length, it also avoid all using high cost caused by metal hose；Wherein, carbon steel seamless steel pipe can design many
Kind of length specification, in the present embodiment, the specification of carbon steel seamless steel pipe have five kinds, respectively 400mm, 600mm, 1000mm,
1200mm and 1500mm；In addition, being additionally provided with hanger on carbon steel seamless steel pipe, the gas extraction system is fixed for lifting.
It should be noted that reserved module can install particular component additional in order to gas extraction system, but need not in gas extraction system
In the case of installing part additional, it can be substituted using carbon steel seamless steel pipe, thereby enhance the adjustable of the gas extraction system.
Further, individual contacts module, automatic compensating module, system fading margin module, reserved module, silencer module and
It can be fixedly connected between exhaust resistance adjustment module using clip with the cooperation of flange, so as to so that two pipes being connected
Part can in the axial direction 360 degree rotation, and compact conformation, occupy little space, good airproof performance.
