Cov kav hlau-yas muaj cov yam ntxwv uas tsis qis dua cov kav dej yas lossis hlau; Tom ntej no, nws yuav piav qhia txog kev sib txuas ntawm cov kav hlau-yas li cas.
Ua ntej tshaj, koj yuav tsum paub seb koj yuav tsum ua haujlwm li cas. Lawm, cov kav dej lawv tus kheej xav tau. Lawv raug muag hauv skeins, thiab lawv zoo li cov hoses dawb siv rau kev ywg dej. Txoj kab uas hla tuaj yeem ua tau raws li hauv qab no: 16, 20, 26, 32 thiab 40 millimeters. Koj yuav tsum txiav txim siab seb txoj kab uas hla uas haum koj tshaj plaws. Kev sib txuas ntawm cov kav hlau-yas rau ib chav tsev ntiav dej feem ntau yog siv cov kav dej nrog txoj kab uas hla ntawm 16 lossis 20 millimeters. Kev muag khoom ntawm cov khoom siv no yog ua los ntawm cov duab kos, yog li nws tsim nyog los txiav txim siab ua ntej qhov yuav tsum tau ua kom ntev ntawm cov dej. Koj yuav tau rewound nyob rau hauv ib daim ntawv raws nraim li ntau metersxav tau. Qhov tom ntej no koj yuav xav tau yog fittings, uas suav nrog couplings, tees, thiab lub luj tshib. Fittings raug xaiv nyob ntawm txoj kab uas hla ntawm cov kav dej. Nws tsim nyog sau cia tias yog tias koj xav tau txuas cov kav hlau-yas nrog cov hlau, ces koj yuav tsum yuav cov couplings thiab lub luj tshib. Koj tsuas yog yuav tsum tau tshuaj xyuas cov kab ntawm ob lub kav dej hauv lub khw kom tus neeg muag khoom teeb meem adapters ntawm qhov ntau thiab tsawg.
Yog tias koj txaus siab rau kev sib txuas cov kav hlau-yas, ces koj yuav xav tau lub ntsuas ntsuas uas tsim los ua kom cov yeeb nkab hauv txoj kab uas hla me ntsis, kom lub khob haum haum yuav haum rau hauv cov yeeb nkab, thaum lub gaskets yuav tsis raug. kom muaj zog siab. Yog hais tias koj tsis calibrate, ces muaj ib tug siab tshwm sim ntawm rupture ntawm lub gasket. Lwm cov cuab yeej tseem ceeb uas koj yuav xav tau rau koj txoj haujlwm yog hacksaw (lossis txiab tshwj xeeb). Koj yuav tsum xaiv ntau qhov sib txawv ntawm cov yuam sij kom haum raws li koj xav tau.
Txhawm rau ua qhov kev sib txuas ntawm cov kav hlau-yas, nws yog ib qho tsim nyog yuav tau ua ntau yam yooj yim manipulations. Txhawm rau pib, nws tsim nyog muab cov txiv ntoo nrog lub tshuab ntxhua khaub ncaws ntawm qhov kawg ntawm cov yeeb nkab hlau-yas. Tom qab ntawd, nrog kev pab los ntawm ib tug caliber, nws yuav tsum tau ua kom lub cheeb ntawm cov yeeb nkab loj me ntsis, uas nws yuav tsum tau screwed rau hauv lub lumen ntawm cov yeeb nkab nrog uniform txav nyob rau hauv ib lub voj voog. Lub cone haum tuaj yeem muab tso rau hauv cov yeeb nkab calibrated. Tom ntej no, koj yuav tsum tau ceev cov txiv ntseej, uas yuav tso cai rau lub tshuab ntxhua khaub ncaws maj mam compress cov yeeb nkab.
Fittings thiab kav dej tuaj yeem txuas nrog cov xov txuas lossis xovxwm tshuab. Thawj rooj plaub yog siv lub tshuab txiav ntse, calibrator, thiab cov ciaj ntswj kho tau. Xovxwm kev sib txuas ntawm cov kav hlau-yas yog siv cov cuab yeej tshwj xeeb. Cov txheej txheem no yooj yim dua, tab sis kev sib txuas tsis tshua muaj kev ntseeg siab. Rau kev ua haujlwm, koj yuav tsum tau siv cov xovxwm. Cov xovxwm fittings muaj ib qho tshwj xeeb yas ntxig nrog lub nplhaib spacer tsim los tswj cov txheeb ze ntawm qhov haum thiab cov yeeb nkab, thiab muab cov rwb thaiv tsev rau cov txheej hauv cov yeeb nkab.
Raws li ib qho ntawm cov ntsiab cai no, nws tuaj yeem txuas cov dej los ntawm kev txiav cov kav dej mus rau qhov ntev thiab xaiv cov fittings.
