Except object described above, feature and advantage, the utility model also has other object, feature and advantage.Below with reference to figure, the utility model is described in further detail.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the fuel nozzle clogged with soot penetration inspection apparatus structure schematic diagram of the utility model preferred embodiment.
Description of reference numerals: 100, feeding device; 200, pipe adapter; 300, transparent pipe; 310, valve; 320, upper groove; 330, lower groove; 400, fixed head.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
With reference to Fig. 1, preferred embodiment of the present utility model provides a kind of fuel nozzle clogged with soot penetration inspection device, and comprise feeding device 100, pipe adapter 200 and transparent pipe 300, feeding device 100 is communicated with by transparent pipe 300 with pipe adapter 200.Transparent pipe 300 is provided with for controlling the flowing of penetrating fluid in transparent pipe 300 or the valve 310 stopped and for the upper groove 320 that reads penetrating fluid liquid level and lower groove 330.
It is comparatively large that the opening of feeding device 100 can be arranged, and less with the opening of transparent pipe 300 junction, so that the penetrating fluid in the external world imports.Feeding device 100 can be various shape as funnel-form, or other be convenient to penetrating fluid import up big and down small shape.Transparent pipe 300 can be the pipe of other transparent material such as plastic tube, glass tube.Transparent pipe 300 can be flexible pipe can be also hard tube, does not affect use, and as being hard tube, transparent pipe 300 can be preferably hard straight tube, to reduce the resistance of penetrating fluid flowing.
The using method of fuel nozzle clogged with soot penetration inspection device is as follows: 1, transparent pipe 300 times grooves 330 are placed in one higher than the level altitude of engine fuel nozzle outlet height, and keeps transparent pipe 300 to be in plumbness.
2, keep that valve 310 is crack in funnel, injects penetrating fluid to discharge air in transparent pipe 300, until liquid level exceeds groove 320 on transparent pipe 300, then valve-off 310 stop fluid injection.
3, carrying out timing to prepare, for ensureing the accuracy of timing, adopting manual time-keeping.
4, by 310 dozens, valve to fully open position, start timing when transparent liquid liquid level for seep arrives groove 320 on transparent pipe 300, when liquid level arrives transparent pipe 300 about groove 330, stopping timing, obtains the time that liquid flows through transparent pipe 300 scale mark.
5, flow through the time of transparent pipe about 300 scale mark for the standard time with the identical penetrating fluid of qualified engine, can judge whether fuel nozzle blocks by actual detection time and standard time.
The utility model has following beneficial effect: feeding device 100 accepts extraneous penetrating fluid and is directed into transparent pipe 300, and penetrating fluid enters in engine through pipe adapter 200.Opening valve 310 makes penetrating fluid flow in transparent pipe 300, is compared with the standard time of specification product the time that the liquid level of penetrating fluid flow to lower groove 330 place from upper groove 320, thus judges whether engine exists the problem of fuel nozzle clogged with soot.Above-mentioned fuel nozzle clogged with soot penetration inspection apparatus structure is simple, easy to use, conveniently can detect whether engine exists fuel nozzle clogged with soot problem.
Alternatively, with reference to Fig. 1, transparent pipe 300 also comprises for making the linearly extended fixed head 400 of the transparent pipe 300 between upper groove 320 and lower groove 330.If transparent pipe 300 is flexible pipe, during detection, transparent pipe 300 easily bends, cause testing environment and standard detection environment inconsistent, affect detection accuracy.Setting fixed head 400, ensures that the partial straight lines of transparent pipe 300 between upper groove 320 and lower groove 330 extends, during mensuration, can ensure that transparent pipe 300 is in plumbness.
Alternatively, fixed head 400 is provided with annular buckle fixing for transparent pipe 300.Transparent pipe 300 is fixed on fixed head 400 by annular buckle, avoids transparent pipe 300 to be out of shape simultaneously, causes measurement structure inaccurate.
Alternatively, fixed head 400 is provided with the length scale reading penetrating fluid liquid level falling head.Be provided with length scale, accurately can read penetrating fluid liquid level falling head, measure more accurate and flexible.
Alternatively, fixed head 400 is white fixed head.When transparent pipe 300 in atmosphere time, be not easy to see penetrating fluid liquid level, upper groove 320 and lower groove 330 clearly.One white fixed head is set, clearly can sees penetrating fluid liquid level, upper groove 320 and lower groove 330 clearly, make measurement result more accurate.
Alternatively, with reference to Fig. 1, feeding device 100 is funnel.Funnel structure is simple, and penetrating fluid can be made to enter fast in transparent pipe 300, makes measuring process more quick convenient.
Alternatively, with reference to Fig. 1, the inwall of pipe adapter 200 is provided with the screw thread for being spirally connected with engine oil inlet pipe.Pipe adapter 200 is connected closely with engine oil inlet pipe, avoids penetrating fluid seepage.
Alternatively, with reference to Fig. 1, valve 310 is arranged at transparent pipe 300 near pipe adapter 200 side, and flowing and the stopping response of penetrating fluid are more quick, make measuring process more quick.
Alternatively, penetrating fluid is water.Penetrating fluid is water, and security is higher, and with low cost.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
