Lub luag haujlwm ntawm lub nozzle hauv lub tshuab txiav laser
Lub nozzle yog qhov tseem ceeb tshaj plaws hauv cov tshuab txiav laser, cuam tshuam loj heev, ua tau zoo, thiab txheej txheem ruaj khov. Nws cov haujlwm tseem ceeb muaj:
1. TXHEEJ TXHEEM KEV PAB ROJ & SIAB
Tsom Xyooj: Lub nozzzzzzzzzzzzzzzzzzzzzzzzzzzzle prener bore (feem ntau 1. {}, Nu, lossis cua compressed) mus rau qhov chaw txiav.
Kev Ua Haujlwm Siab Zoo: Cov ntaub ntawv sib txawv (piv txwv li, stainless hlau, txhuas) yuav tsum muaj cov roj pev (feem ntau {}}. 5-20 bar). Lub Nozzzzzle tus tsim ua kom muaj kev tshem tawm sloticless thiab txhawb nqa extrothermic cov tshuaj tiv thaiv (piv txwv li rau cov hlau oxidation).
2. Kev tiv thaiv kho qhov muag
Tiv thaiv kev paug: cov roj flow tsim ib qho teeb meem, thaiv cov nplais molten thiab hmoov av los ntawm kev tso nyiaj ci zoo lossis ua rau overheating.
Cov nyhuv txias: Qee cov qauv tsim siv cua txias kom txias lub lens periphery, nthuav tawm nws lifespan.
3. Txhim Kho Kev Txiav Zoo & Precision
Clears molten cov khoom siv: blows pov tseg slag kom tiv thaiv kev rov qab rov qab, ua kom huv si txiav (tseem ceeb rau cov hlau tsis huv thiab txhuas).
Txhim kho ntug kom tiav: kom muaj roj flow minimizes burrs thiab drossasn, tsim cov ntaub qhwv ntsej muag (piv txwv li, nog txiav rau oxidation-dawb stainless hlau npoo).
Beam Filel Kev Pab: Qee cov duab nozzle cov duab (piv txwv li, conical) pab tswj cov poral zoo ntawm cov khoom siv tuab.
4. Boosting txiav ceev & txuag
Gas Dynamics optimization: Tshwj xeeb nozzles (piv txwv li cov roj ua kom zoo dua qub, txhim kho kev nkag mus thiab nce kev txiav nyiaj ntau ntxiv).
Txo cov kev tiv thaiv ntshav ntshav ntshav: hauv kev txiav txim siab kom muaj zog, pab cov pa hluav taws xob plasma uas nqus lub zog tsim kom haum, ua kom tiav kev txiav tawm.
5. Adapting rau cov txheej txheem yuav tsum tau
Cov Khoom Siv & Roj Sib Xws:
O₂ rau cov roj carbon hlau: txhawb nqa lwm yam kev phiv tshuaj.
N₂ rau txhuas: Yuav tsum muaj qhov loj dua thiab siab dua rau cov kev txiav kom huv.
Tsim Tshwj Xeeb:
Dual-txheej Nozzles: Cov channel hauv kev txiav roj, sab nraud rau kev thaiv cov roj (siv rau cov khoom siv zoo li tooj liab).
Key Nuzz tsis raug
Inch: me me (1. {{{}}}}} {} Mm mm) rau cov ntawv nyias nyias; Loj (3. {0} - 5. {{{}} nplej} hli) rau cov ntaub ntawv tuab.
Concentricity: Misalignment >{{0 {0}}. 05 hli ua rau kev txiav lossis cov roj tsis sib xws.
Cov khoom siv: tooj (ruaj khov, kos) yog qauv; Ceramic-coated variants txhim kho ntev.
Cov kev saib xyuas tswv yim
Kev Txij Nkawm: Nquag ntxuav lub nozzle bore kom tiv thaiv clogging (dispted Airflow degrades txiav).
Hloov: hnav: hnav lossis deformed nozzles yuav tsum tau hloov los tswj qhov tseeb.
Sawv ntsug ze: Feem ntau {{0}}}. 5-2.0 hli; Qhov siab tsis raug txo cov roj ua tau zoo lossis kev pheej hmoo sib tsoo.
Tag
Lub nozzle tsom kho cov roj teeb tsis meej, thiab cov kev hloov kho lub zog-ncaj qha tiv thaiv kev txiav zoo, thiab cov nqi khiav haujlwm. Kev xaiv kom tsim nyog (qhov loj me, siab, sincment) yog qhov tseem ceeb rau cov txheej txheem kev sib txuas hauv cov ntawv txheej laser.
