Injector Nozzle Internal Borescope - HD Professional Edition - Sub-Ntoo nthuav dav daws teeb meem nrog kev ntsuas kab sib xyaw

Hauv kev saib xyuas cov kev tsheb ciav hlau feem ntau, qhov sib txawv ntawm qhov kev pabcuam nozzle thiab ib qho uas yuav tsum tau hloov pauv feem ntau nyob rau hauv qhov tsis xws luag me dua 50 µm - micro-cracks pib ntawm lub rooj zaum, cavitation thaum ntxov, lossis cov kua roj vanish hla hla lub qhov nkag. Standard-resolution borescopes (640 × 480) yuav ntes tag nrho cov kab mob tab sis nquagtsis dawscov sub-surface anomalies mus txog rau thaum lawv tau nce mus rau qhov chaw uas qhov kev ua tau zoo twb raug cuam tshuam lawm. CovInjector Nozzle Internal Borescope - HD Professional Editionrhuav tshem qhov kev txwv no nrog 1.2-megapixel sensor thiab mob siab raukev hloov kho micro-focus, xa cov duab clarity uas nthuav tawm cov qauv nplej ntawm lub rooj zaum koob thiab cov geometry meej ntawm cov npoo ntawm cov npoo. Qhov no tsis yog ib daim duab sharper xwb – nws yog ibkuaj qhov pibuas tso cai rau cov kws tshaj lij kom paub qhov txawv ntawm qhov staining thiab cov khoom siv tiag tiag degradation.

Lub borescope yog tsim los tshuaj xyuas nozzles nrog orifice diameters los ntawm1.5mm txog 5.5mm. Lub HD version suav nrog lub slimmer 3.2 mm insertion sojntsuam, tso cai rau nkag mus rau nqaim-inlet injectors uas tsis sib haum nrog 4.0 mm txheem sojntsuam.

1. Micro-Focus Adjustment Nplhaib

Tsis zoo li cov borescopes ruaj khov, HD version suav nrog aphau ntawv micro-focus nplhaibntawm qhov kev sojntsuam kov, tso cai rau tus neeg teb xov tooj kom kho lub dav hlau focal ntawm 3 hli mus rau 35 hli. Qhov no yog qhov tseem ceeb rau kev tshuaj xyuas lub rooj zaum koob - feem ntau recessed 8-12 mm nyob rau hauv lub nozzle - thiab cov tshuaj tsuag qhov nkag (5-8 mm), nrog tib lub sojntsuam. Lub nplhaib tsom yogknurled thiab colour-coded(ntsuab rau ze, liab rau deb), ua kom hloov tau sai txawm tias cov hnab looj tes oily.

2. Dual-Zone Illumination nrog Glare Suppression

Lub 8 LEDs yog teem rau hauv ob lub nplhaib concentric. Lub nplhaib sab hauv illuminates qhov chaw ntawm lub tshav pob (rau koob lub rooj nthuav dav), thaum lub nplhaib sab nrauv muab sab-teeb pom kev zoo nkauj thiab qhov tob (rau cavitation pits thiab kua roj vanish). Tus neeg teb xov tooj tuaj yeemkho nws tus kheejqhov ci ntsa iab ntawm txhua lub nplhaib - ib qho tshwj xeeb uas tshem tawm qhov kev xav pom ntawm qhov pom ntawm cov hlau polished, nthuav tawm qhov tseeb ntawm qhov chaw es tsis yog cov duab ntxuav tawm.

3. Integrated Measurement Grid – Dimensional Reference

A reticulated overlay- daim phiaj precision nrog 0.1 hli sib faib - tuaj yeem muab tso rau ntawm daim duab nyob ntawm lub pob ntawm cov zaub. Thaum lub borescope nyob rau ntawm qhov chaw paub txog (siv qhov chaw ua kom pom tseeb), daim phiaj muab ib qho kev kwv yees rau kev kwv yees qhov ntau thiab tsawg: qhov taub, qhov ntev tawg, lossis cov kua roj vanish feem pua. Qhov no hloov qhov kev tshuaj xyuas los ntawm qhov zoo "zoo li qias neeg" mus rau akev soj ntsuam quantifiable, tso cai rau kev txiav txim raws li kev txiav txim siab tsis yog kev txiav txim siab.

Hauv kev tswj xyuas kev siv lub tshuab siv lub taub hau uas paub qhov tsis xws luag (EDS-tuaj xyuas):

Micro-crack detection: Chav tsev HD daws qhov 25 µm tawg ntawm lub rooj zaum koob - pom tsis pom ntawm tus qauv 640 × 480 (uas tsuas yog pom qhov muag plooj).

Qhov luaj li cas: Siv daim phiaj ntsuas, cov neeg ua haujlwm kwv yees lub qhov taub nrog qhov yuam kev nruab nrab ntawm ± 7 µm (piv rau SEM ntsuas).

Cov kua roj vanish: Lub teeb pom kev zoo dual-zone tau nthuav tawm cov kua roj vanish thaum ntxov (thickness<5 µm) on spray hole walls, which appeared as a smooth surface under single‑source illumination.

Hauv kev sim teb thoob plaws 56 cov tshuaj txhaj tshuaj (tag nrho cov hom), cov kws tshaj lij tau tshaj tawm tias chav HDtxo qhov tsis tsim nyog nozzle hloov los ntawm 22%- vim hais tias lawv tuaj yeem ntseeg tau tias qhov pom tseeb "kev puas tsuaj" tsuas yog staining superficial, tsis yog cov khoom ploj.

Q1: Dab tsi yog qhov txiaj ntsig tiag tiag ntawm HD version dhau tus qauv version?
HD version daws cov ntsiab lus mus rau 15-20 µm, thaum tus qauv version daws ib ncig ntawm 50-60 µm. Qhov no txhais tau hais tias koj tuaj yeem pom cov micro-cracks thiab cov cavitation thaum ntxov ua ntej lawv dhau los ua kev txwv kev ua haujlwm, ua kom muaj kev pabcuam zoo dua li kev hloov pauv. Nws kuj tseem suav nrog daim phiaj ntsuas rau kev kwv yees qhov tsis xws luag - qhov tshwj xeeb tsis muaj nyob rau ntawm chav tsev txheem.

Q2: Kuv puas tuaj yeem siv daim phiaj ntsuas los txiav txim siab seb lub nozzle puas tseem nyob rau hauv kev zam?
Daim phiaj qhia txog kev kwv yees qhov loj ntawm qhov pom qhov tsis xws luag (piv txwv li, qhov taub, qhov ntev tawg). Txawm li cas los xij, nws tsis yog qhov hloov pauv rau calibrated metrology (piv txwv li, profileometer). Nws yog npaj los ua cov cuab yeej tshuaj ntsuam - yog tias daim phiaj qhia tias muaj qhov tsis xws luag mus txog 0.1 hli, lub nozzle yuav tsum tau ntsuas ntxiv lossis hloov. Phau ntawv muab ib daim ntawv qhia txog cov kev txwv ib txwm siv.

Q3: Lub teeb pom kev zoo dual-zone pab nrog cov pa roj carbon npog li cas?
Carbon deposits feem ntau tsaus nti thiab nqus lub teeb; lub nplhaib sab nrauv illumination muab oblique teeb pom kev zoo uas qhia txog kev ntxhib los mos thiab topography, ua carbon buildup kom meej meej distinguishable ntawm lub hauv paus hlau nto. Lub nplhaib puab, thaum siv ib leeg, nyiam ntxuav tawm cov yam ntxwv hloov maj mam - peb pom zoo kom siv ob lub nplhaib ua ke, tab sis nrog lub nplhaib puab teeb rau qis dua.

Q4: Puas yog qhov kev sojntsuam siv tau nrog cov tshuaj txhaj tshuaj uas muaj cov ntxaij lim dej built-in?
Lub 3.2 hli txoj kab uas hla kev sojntsuam haum los ntawm feem ntau inlet ports, tab sis yog hais tias lub injector muaj ib tug khaws cia cov ntxaij lim dej nyob rau hauv nkag, tej zaum koj yuav tau tshem nws ua ntej - qhov no yog ib tug cais kev pab cuam. Kev sojntsuam tsis yog tsim los txhawm rau txhawm lossis hla cov lim dej; ib txwm tshem tawm cov kev cuam tshuam ua ntej kev ntxig kom tsis txhob ua rau qhov kev sojntsuam puas.

Q5: Kuv yuav ua li cas thiaj paub yog tias qhov tsom xam raug teeb tsa rau daim phiaj ntsuas kom raug?
Daim phiaj yog ntsuas ntawm peb txoj haujlwm tsom: ze (5 hli), nruab nrab (10 hli), thiab deb (20 hli) - cov no tau cim rau ntawm lub nplhaib tsom. Rau qhov sizing raug, xyuas kom meej lub nplhaib tsom mus rau txoj hauj lwm uas muab cov duab sharpest. Daim phiaj teev ntsuas yog kwv yees - peb pom zoo kom siv nws los ua ib qho cuab yeej sib piv es tsis yog ib qho kev ntsuas kiag li.

Q6: Kuv puas tuaj yeem siv HD borescope rau cov tshuaj txhaj tshuaj los ntawm cov tshuab qub (tsis yog-CR)?
Yog - qhov kev sojntsuam ua haujlwm ntawm txhua lub nozzle nrog qhov chaw nres nkoj loj txaus (Ntau dua lossis sib npaug li 3.5 hli). Qhov kev daws teeb meem HD yog qhov tshwj xeeb tshaj yog siv rau kev kuaj pom kev hnav ntawm cov neeg kho tshuab injector nozzles uas ua haujlwm ntawm qis qis tab sis raug rau kev yaig mus ntev. Txawm li cas los xij, cov lus qhia rau sab-saib daim iav yog tsim los rau kev tsheb ciav hlau geometry - rau cov laus pintle-type nozzles, kev pom rau pem hauv ntej (0 degree) yog qhov tseem ceeb tshaj.
