Cov lus qhia no ua kom yooj yim rau cov txheej txheem xaiv rau hauv cov kauj ruam meej, nrog cov kws tshaj lij cov lus qhia los pab cov novices kom tsis txhob muaj kev cuam tshuam ntau.

 

Kauj ruam 1: Nkag siab koj daim ntawv thov

Ua ntej xaiv tus tswj lub siab, koj yuav tsum paub tias koj siv nws li cas. Cov daim ntawv thov txiav txim siab tus tswj hom, cov ntaub ntawv, thiab nta.

1.1 Koj tswj cov kua dej dab tsi?

Cov kua dej (gas lossis kua) cuam tshuam rau tus tswj tus qauv tsim:

• Roj: Cov pa roj carbon monoxide muaj xws li nitrogen (inert), oxygen (oxidizing), hydrogen (flammable), lossis ammonia (corrosive). Txhua tus xav tau cov ntaub ntawv tshwj xeeb kom tsis txhob muaj kev cuam tshuam.

• Kua dej: Dej, roj, los yog tshuaj tej zaum yuav xav tau cov regulators uas tuav viscosity ntau dua los yog corrosion.

• Tshwj Xeeb Cov Mob: Ultra-ntshiab gases (xws li, rau semiconductors) los yog kho mob gases (xws li, oxygen) yuav tsum tau regulators uas tiv thaiv kom txhob muaj kab mob.

Piv txwv li: Yog tias koj tab tom vuam, koj tuaj yeem siv argon (CGA 580 coupling), xav tau lub tshuab tooj dag. Rau cov roj corrosive zoo li cov tshuaj chlorine, lub tshuab hluav taws xob stainless hlau muaj kev nyab xeeb dua.

Cov Lus Qhia Tshwj Xeeb: Txheeb xyuas cov ntaub ntawv kev nyab xeeb ntawm cov roj los yog kua (SDS) kom nkag siab txog nws cov khoom (xws li flammable, corrosive). Nug koj tus neeg muab khoom kom pab yog tias tsis paub meej.

 

1.2 Lub Hom Phiaj yog dab tsi?

Xav txog txoj haujlwm tshwj xeeb:

Kauj Ruam 2: Txiav txim siab qhov xav tau ntawm qhov siab thiab ntws

Siab thiab ntws yog lub plawv ntawm regulator xaiv. Koj yuav tsum paub cov input siab (los ntawm qhov chaw), tso zis siab (rau koj cov khoom siv), thiab tus nqi txaus (koj xav tau dej npaum li cas).

2.1 Input thiab Output Siab

• Input Siab: Lub siab los ntawm koj qhov chaw, zoo li lub tog raj kheej roj (xws li, 3000 psi rau nitrogen) lossis cov kav dej. Xyuas lub tog raj kheej daim ntawv lo los yog qhov system specs.

• Tso zis siab: Lub siab koj cov cuab yeej xav tau (piv txwv li, 50 psi rau vuam teeb, 100 psi rau cov tshuaj reactor). Qhov no feem ntau tau teev nyob rau hauv phau ntawv qhia khoom siv.

• ntau: Xaiv lub regulator nrog lub qhov hluav taws xob siab ntau yam uas suav nrog koj lub hom phiaj (piv txwv li, 0-200 psi rau 100 psi xav tau).

Piv txwv li: Lub tshuab hluav taws xob roj hluav taws xob tuaj yeem muaj 5000 psi lub tog raj kheej (cov tswv yim) thiab xav tau 150 psi tso zis. Lub regulator yuav tsum ua ob qho tib si.

Cov Lus Qhia Tshwj Xeeb: Rau kev nyab xeeb, xaiv tus tswj hwm ntsuas siab tshaj koj qhov siab tshaj plaws cov tswv yim (piv txwv li, 6000 psi rau 5000 psi lub tog raj kheej). Xyuas kom lub qhov hluav taws xob ntsuas pom koj lub hom phiaj siab kom meej.

 

2.2 Flow Rate

Tus nqi ntws yog cov kua dej ntau npaum li cas, ntsuas hauv litres ib feeb (LPM) rau cov pa roj lossis nkas loos ib feeb (GPM) rau cov kua. Tshawb xyuas koj cov khoom siv cov kev xav tau ntws:
