Cavitation Sab hauv High-Pressure Optically Transparent Roj Injector Nozzles(PIB 5)

Rau kev tsom xam, kev txhaj tshuaj siab ntawm cov cuab yeej tiag tiag (800 bar) tau siv los ua tus ciam teb rau thaj chaw sab hauv ntawm acrylic nozzle daim.Muab hais tias cov ntaub ntawv nkig feem ntau ua tsis tau rau qhov nro, sapphire clamps tau ntxiv rau tus qauv tsim kom compress lub nozzle los ntawm sab nraud thiab txo qis zog tensile ntawm sab hauv.Txij li thaum cov clamps nyob rau sab nraud ntawm lub nozzle, cov khoom siv optically pob tshab yuav tsum tau siv rau lawv cov kev tsim kho.

Sapphire tau raug xaiv vim nws cov kav ntev.Hauv kev nkag siab, qhov no ua rau sapphire clamps cov khoom thauj khoom ntawm lub nozzle, txawm tias cov khoom uas lub siab tau thov ncaj qha yog ua los ntawm acrylic.

Qhov kawg tsim nrog 3 sapphire clamps, fabricated thiab assembled, yog qhia nyob rau hauv daim duab 1. Lub qhov ntev ntawm lub nozzle yog 21.5 hli nyob rau hauv saib kev taw qhia nyob rau hauv daim duab 1 thiab 6.75 hli nyob rau hauv txoj kev ntsug.O-ring seals yog siv rau ntawm ob sab ntawm lub nozzle.

3 Cov txiaj ntsig thiab kev sib tham

Qhov kev tsim no tau sim nrog cov roj diesel muab los ntawm kev lag luam reciprocating piston twj tso kua mis nrog 3 theem, tsav los ntawm lub tshuab hluav taws xob loj.Lub sijhawm txhaj tshuaj thawj zaug tau teem rau 250ms, tab sis lub hnab ntim siab ntsuas tau qhia tias lub twj tso kua mis tsis muaj peev xwm txhawb nqa qhov kev tswj hwm siab rau tag nrho lub sijhawm.Lub sijhawm txhaj tshuaj tau tshwm sim yog kwv yees li 100ms, thiab lub sijhawm txhaj tshuaj tau qeeb qeeb qeeb thaum lub sijhawm no.

Cov dej ntws hauv lub nozzle tau raug ntes nyob rau hauv ib qho kev teeb tsa transillumination nrog lub koob yees duab Phantom V1210 high-speed.Vim lub ambient yog atmospheric rov qab siab, lub orifice flow cavitated yooj yim.Ib daim duab sawv cev nrog rau kev txhaj tshuaj siab ntawm 350 bar yog qhia hauv daim duab 2. Ib daim duab tag nrho ntawm cov dej ntws sab hauv nrog rau cov dej ntws thiab cov tshuaj tsuag hauv cheeb tsam ntawm cov dej ntws no kuj tau muab.Qhov xwm txheej no yog nyob ntawm Reynolds tus lej ntawm kwv yees li 85,000.
