Diesel Injector 320-0677 Roj Injector 2645A746 Injector Tau tshaj Caterpillar Cat C6.6 Cav 320dl Excavator

Cavitation Sab hauv High-Pressure Optically Transparent Roj Injector Nozzles(PIB 1)

Kev Taw Qhia Qhov siab txhaj tshuaj siab thiab lub tshuab microscopic nozzle orifices yog siv rau hauv cov tshuab txhaj tshuaj hauv cov tshuab ncaj qha niaj hnub los txhim kho atomization thiab xa cov roj txaus sai. Cov dej ntws hauv cov twj tso kua mis yuav tsum tig nrawm nrawm kom nkag mus rau lub nozzle qhov ncauj, uas feem ntau ua rau cavitation tshwm sim nyob rau sab qis ntawm lub orifice inlet ces kaum. Cavitation feem ntau suav hais tias yog ib qho kev phom sij, vim tias kev sib tsoo cavitation npuas tuaj yeem ua rau qhov chaw ntawm cov hlau ruaj khov xws li cov hlau tawv tawv. Tsis tas li ntawd, thaum qee hom cavitation tau pom tias muaj txiaj ntsig zoo rau atomization, txawm tias tshem tawm cov pa roj carbon deposits hauv cov roj av injectors, hydraulic flip suppresses atomization tag nrho[1]. Txog rau thaum cavitation tau nkag siab zoo dua thiab tswj tau yooj yim dua, nws zoo li qhov tsim nyog los tsim lub tshuab nozzle hauv txoj hauv kev xws li tiv thaiv cavitation. Txoj hauv kev zoo tshaj plaws rau kev kawm nozzle orifice flow cavitation yog tsim kom muaj ib lub injector nrog ib qho optically siv tau nozzle kom lub orifice ntws tuaj yeem pom ncaj qha. Qhov no tsis yog ib txoj haujlwm yooj yim. Optically pob tshab engineering cov ntaub ntawv feem ntau nkig ntawm chav tsev kub. Thaum cov ntaub ntawv nkig feem ntau muaj ntau dua elastic moduli thiab muaj zog theoretical zog, flaws tshuav los ntawm kev ua yuav tsum tau los tsim cov yam xav tau geometry tuaj yeem txo qhov peev xwm ntawm cov khoom tiav. Ib qho teeb meem tseem ceeb nrog cov lus qhia kho qhov muag yog nrhiav qhov sib tw ntawm qhov ntsuas ntawm refraction rau cov khoom siv nozzle thiab cov kua dej siv. Yog tias lawv tsis sib haum, ces cov npoo ntawm qhov kev yuav tshwm sim tsaus nti hauv shadowgram. Qhov ntawd yuav ua rau nws nyuaj rau duab phab ntsa cavitation.

Acrylic thiab quartz muaj qhov Performance index uas los ze rau ntawm cov roj feem ntau (thiab dej) tab sis hmoov tsis lawv muaj lub zog tensile tsawg vim kev ua tsis zoo. Lawv feem ntau tawg zoo hauv qab qhov tseeb roj siab. Sapphire, ntawm qhov tod tes, muaj cov khoom siv hluav taws xob thiab lub zog zoo ib yam li cov hlau, tab sis nws tsis zoo sib xws nrog cov kua dej txaus nyiam.
