Dizilo Injector 320-0677 Fuel Injector 2645A746 Injector Yogwirizana ndi Caterpillar Cat C6.6 Engine 320dl Excavator

Cavitation M'kati mwa High-Pressure Optically Transparent Fuel Injector Nozzles(GAWO 1)

Chiyambi Mapiritsi okwera a jakisoni ndi mazenera ang'onoang'ono am'mphuno amagwiritsidwa ntchito m'makina a jakisoni mumainjini amakono opangira jakisoni kuti apititse patsogolo ma atomu ndikupereka mafuta okwanira mwachangu. Kuthamanga mkati mwa jekeseni kuyenera kutembenuka mwadzidzidzi kuti mulowe m'mphepete mwa mphuno, zomwe nthawi zambiri zimapangitsa kuti cavitation iwonekere kumunsi kwa ngodya ya orifice. Cavitation nthawi zambiri imawonedwa ngati yowopsa, chifukwa kugwa kwa thovu la cavitation kumatha kuwononga malo azitsulo zolimba monga zitsulo zolimba. Kuonjezera apo, pamene mitundu ina ya cavitation yasonyezedwa kuti ndi yopindulitsa kwa atomization, ngakhale kuchotsa carbon deposits mu petulo injectors, hydraulic flip suppresses atomization kwathunthu[1]. Mpaka cavitation imamveka bwino komanso yosavuta kuwongolera, zikuwoneka zomveka kupanga jekeseni wa jekeseni m'njira yoteteza cavitation. Njira yothandiza kwambiri yophunzirira nozzle orifice flow cavitation ndikupanga jekeseni yokhala ndi nozzle yofikirika bwino kuti kutuluka kwake kuwonekere mwachindunji. Iyi si ntchito yophweka. Zipangizo zamainjiniya zowoneka bwino nthawi zambiri zimakhala zolimba kutentha firiji. Ngakhale zida zowonongeka nthawi zambiri zimakhala ndi zotanuka moduli komanso mphamvu zamphamvu zongoyerekeza, zolakwika zomwe zimasiyidwa pakukonza kofunikira kuti mupange geometry yomwe mukufuna imatha kuchepetsa kwambiri katundu wagawo lomalizidwa. Nkhani yofunika yokhala ndi nsonga za kuwala ndikupeza machesi pakati pa ma index of refraction a nozzle material ndi madzimadzi omwe amagwiritsidwa ntchito. Ngati sizikufanana, ndiye kuti m'mphepete mwa ndimeyi mudzawoneka mdima mumthunzi. Izi zingapangitse kuti zikhale zovuta kufotokoza khoma la cavitation.

Acrylic ndi quartz ali ndi index yomwe imayandikira pafupi ndi mafuta ambiri (ndi madzi) koma mwatsoka amakhala ndi mphamvu zochepa chifukwa cha zolakwika za kukonza. Nthawi zambiri amasweka bwino pansi pa mphamvu zenizeni zamafuta. Sapphire, kumbali ina, imakhala ndi matenthedwe komanso mphamvu zofananira ndi chitsulo, koma sizimafanana bwino ndi madzi osangalatsa.
