Description
Technical field
The invention belongs to engine test technical field, more particularly, to cigarette under the big condition of negative pressure of plateau simulated exhaust
Spend the conversion equipment of test.
Background technology
In the geographical environment in the world, China plateau has the characteristics of height above sea level and wide area, height above sea level 1000m, 2000m and
More than 3000m plateau region accounts for 58%, 33% and the 26% of the national land gross area respectively, is particularly known as " roof of the world "
Qinghai-Tibet Platean, more than mean sea level 4000m, area is up to 2,300,000 sq-kms.It is high with the implementation of strategy to develop western regions
Original area's driving vehicle is more and more.As the engine of vehicle power source, its performance also necessarily turns into one of product development
Important indicator.
Engine Performance on Plateau test method mainly has two kinds, and one kind is that engine direct is hinged with car or with container-type with car
Directly upper highlands carries out various performance optimizations and demarcation, and another laboratory in altitude environment simulation carries out engine
Various optimizations.Although first way environmental condition is true, expose that problem is actual, due to the office of field test facility
Limit, a lot of experiment or test contents can not effectively carry out, along with long test period and large number quipments transport carry so that this
Kind test method is only carried out in final identification.Compared to first way, the test method of the second laboratory more flexibly, equipment more
Added with guarantee, it is easier to received by R＆D and production mechanism or unit.
In the engine plateau simulated test that laboratory carries out, exhaust smoke is characterize engine performance characteristics one
Important indicator.However, when carrying out the plateau simulated test compared with High aititude height, have very due to comparing atmospheric environment in blast pipe
Big negative pressure, measured so that commercially available various smokemetors can not directly gather exhaust.
Based on above-mentioned consideration, it is necessary to develop a kind of plateau simulated exhaust condition smoke intensity test conversion equipment to meet bavin
The exhaust smoke measurement request proposed during the simulating bench experiment of oil machine plateau.
The content of the invention
In view of this, the invention is directed to plateau simulated exhaust condition smoke intensity test conversion equipment, to provide
A kind of device simple in construction, easy to operate, can effectively solving Smoke Measurement under the conditions of the simulated exhaust of plateau.
To reach above-mentioned purpose, what the technical scheme of the invention was realized in：
Plateau simulated exhaust condition smoke intensity test conversion equipment, including moving cart, first sampling pipeline, sampling pump,
Steady-flow tank, pad, nut, gas collector, pressure regulation vent valve, sealing gasket, overflow pipe, installation flap, the second sampling pipeline, institute
State sampling pump intake connection first sampling pipeline, outlet by connection second sampling pipeline be connected with steady-flow tank, sampling pump with surely
The support of stream tank is fixed in moving cart in the form of bolt connection, and sampling pipeline stretches into current stabilization pot bottom and with pad and nut
Sealing fastening, gas collector are fastenedly connected with external screw thread with stretching into the second sampling pipeline of steady-flow tank, and installation flap passes through close
Packing is threadedly coupled with steady-flow tank, and installation flap center arrangement has smokemetor test probe mounting seat, and side is disposed with band pressure regulation
The overflow pipe of vent valve.
Further, the gas collector is the integrated structure of hollow cylinder and hollow ball, and spheroid the upper half is justified
Circumferential direction is evenly distributed with aperture, and the circular hole more than smokemetor test probe caliber is distributed with top center.
Further, gas pressure can pass through pressure regulation Waste gate in the steady-flow tank.
Relative to prior art, the plateau simulated exhaust condition smoke intensity test conversion device described in the invention have with
Lower advantage：
(1) the plateau simulated exhaust condition smoke intensity test conversion device described in the invention, sampling pump, which can gather, to be started
The exhaust of big negative pressure in machine blast pipe, it is delivered to smokemetor test probe port and is used to measure.
(2) gas collector described in the invention can accumulative sampling pump conveying gas, its upper circular is small also may be used
Excess pressure gas is discharged, smokemetor test probe port air-flow is tended towards stability, so as to ensure smokemetor normal work.
(3) the pressure regulation vent valve described in the invention, the pressure that can adjust gas in steady-flow tank are arranged with reaching smokemetor
The optimum pressure of gas smoke measurement, while the residual gas that collection is deposited in toilet-cleaning jar in time.
