Thaum cov kav dej qub hauv chav tsev rots, fistulas thiab hws tshwm sim ntawm cov kav dej, nws yuav tsum tau nruab ib lub tshiab. Koj tuaj yeem ua koj tus kheej, yam tsis tau txais daim ntawv tso cai thiab tsis muaj ntaub ntawv. Koj yuav tsum tau tua cov dej hauv cov risers, thiab tom qab ntawd mus ua haujlwm, tom qab ntawd koj tuaj yeem siv cov txheej txheem tshiab tau ntau xyoo.
txheej txheem hloov kav
Yog tias koj pib lub installation ntawm cov kav dej, tom qab ntawd koj yuav tsum tau coj los ntawm ib qho kev siv tshuab, uas nyob rau hauv thawj theem muab kev xaiv ntawm cov khoom, nrog rau cov kab kos rau cov dej txias thiab kub. Cov kauj ruam tom ntej no yuav yog kev txhim kho cov txheej txheem dej, nrog rau kev suav ntawm txoj kab uas hla ntawm cov kav dej raws li cov khoom siv. Tus tswv npaj cov cuab yeej teeb tsa, yuav cov khoom siv, thiab tseem rhuav tshem cov kav dej qub thiab cov kav dej.
rau kev siv
Tom qab cov kav dej tshiab tau teeb tsa, koj tuaj yeem txuas thiab txuas cov kav dej. Thaum kawg, lub boiler yog ntsia thiab txuas,yog muab los ntawm lub tswvyim.
Kev xaiv cov khoom siv yeeb nkab
Kev teeb tsa cov yeeb nkab tuaj yeem ua tiav tom qab kev yuav khoom. Txawm li cas los xij, thawj kauj ruam yog xaiv cov khoom siv. Copper tuaj yeem ua raws li nws, tab sis qee tus kws tshaj lij tsis qhia siv nws, vim tias, hauv kev sib cuag nrog dej, cov khoom no tuaj yeem tsim cov oxide cuprous.
Hlau-yas tau siv feem ntau tsis ntev los no, cov kav dej zoo li no kim heev, tab sis koj tuaj yeem txuas rau lawv tus kheej yam tsis muaj kev paub dhau los. Cov yeeb nkab hlau-yas dej txuas nrog cov xov txuas nrog cov fittings lossis gaskets. Cov khoom zoo li no tuaj yeem khoov tau, thiab hydrodynamic tsis kam thiab siab poob yuav tsawg heev. Txhawm rau ntxig cov yeeb nkab zoo li no rau hauv qhov haum, koj yuav xav tau cov hlua khi, cov yeeb nkab cutter thiab ib txheej ntawm reamers. Ntawm lwm yam, lub neej kev pab cuam ntawm gaskets nyob rau hauv fittings yog txwv. Qhov no yuav tsum paub yog tias koj yuav zais cov kav dej.
Tseem daws teeb meem
Kev teeb tsa cov yeeb nkab tuaj yeem ua tiav raws li cov khoom siv yas, uas tau lees paub niaj hnub no. Koj tuaj yeem siv polybutylene nrog kev kho tau zoo, polyethylene uas pheej yig tab sis tsis tuaj yeem tiv taus qhov kub siab tshaj 60 ° C, thiab PVC uas paub zoo txog nws cov tshuaj tiv thaiv, tsis tshua muaj nqi thiab kub tsis kam mus txog 80 ° C.
Piping installation: kos duab kab kos
Kev teeb tsa cov yeeb nkab tuaj yeem ua tiav raws li ib qho ntawm ob lub tswv yimdrawdown, nws yuav ua tau parallel thiab sequential. Nyob rau hauv rooj plaub tom kawg, cov ntsiab lus parsing yuav tsum tau txuas nrog cov yeeb nkab uas siv tees. Cov tswv yim no suav hais tias yog qhov kev lag luam tshaj plaws, tab sis nrog cov txiaj ntsig zoo ntawm cov ntsiab lus parsing lossis tsis tshua muaj siab, nws tsis tsim nyog, vim nws txo qis heev. Hauv qhov no, koj tuaj yeem siv lub voj voog sib luag uas cov li qub tswj lub siab taw tes los ntawm taw tes.
Txoj kev teeb tsa ntawm cov kav dej
Yog tias koj txiav txim siab los nruab cov kav dej nrog koj tus kheej tes, tom qab ntawd thawj theem koj yuav tsum tau nruab arcs, uas yog cov hlua yas rau cov khoom sib tov. Lawv yuav tsum tau kho rau lub ntsiab phab ntsa nrog dowels. Thaum kho, xav txog qhov tuab ntawm qhov tiav, xws li cov vuas lossis plaster.
Cov kauj ruam tom ntej yog los sib sau cov kav dej. Cov cuab yeej siv tau yooj yim tshaj plaws yog kev sib dhos ntawm lub rooj thiab txuas ntxiv cov kav dej. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv no, cov lus nug yuav tshwm sim ntawm yuav ua li cas rau cov kav dej los ntawm cov phab ntsa. Yog tias koj siv hlau-yas, ces yuav tsis muaj teeb meem tshwj xeeb, txij li nws tau sib sau ua ke siv cov khoom sib dhos, thaum rau cov kav dej brazed, koj tuaj yeem siv ib qho ntawm cov hauv qab no.
Nws raug nquahu kom siv cov adapters thiab cov hlau-yas ntxig. Rau ib chav tsev, txoj kev no yuav txhim khu kev qha, thiab nyob rau hauv cov ces kaum saum cov kav dej nws yog ib qho tsim nyog los ua kom tshem tau cov kaus mom rau kev kho cov xov sib txuas thiab kev kho dua tshiab. Txawm li cas los xij, nws muaj peev xwm txhim kho cov kav dej hauv qhov chaw, rau qhov nosiv lub compact soldering hlau. Nws raug nqi ntau dua, thiab koj yuav tsum ua haujlwm nrog nws hauv hnab looj tes paj rwb kom tsis txhob hlawv.
Tom qab koj tuaj yeem txiav cov kav dej, koj tsis tuaj yeem pom lawv, uas yog qhov tseeb tshwj xeeb rau cov hlau-yas. Koj yuav tsum tau txiav nrog cov yeeb nkab cutter; rau hlau-yas thiab yas, xws li cov cuab yeej muaj cov yam ntxwv sib txawv. Cov kauj ruam tom ntej yuav yog soldering, ib tug ntawm lawv siv 15 mm ntawm cov yeeb nkab. Nws tuaj yeem muaj ib lub 'meter' ntawm ob lub fittings, rau qhov no, 1030 hli yuav tsum raug txiav tawm. Yog hais tias nruab nrab ntawm lawv yog 0.6 m, ces nws yog tsim nyog los txiav tawm ib tug workpiece ntawm 630 mm. Thaum lub installation ntawm cov kav dej yog nqa tawm, ces nyob rau theem tom ntej lawv yuav tsum tau khoov, qhov tsawg kawg nkaus lub vojvoog tso cai yog 5 txheej diameters. Tsis txhob siv xuab zeb rau qhov no, uas tau liam tias pab khoov cov khoom rau txhua lub kaum ntse ntse. Nyob rau hauv cov ntaub ntawv no, cov txheej sab hauv deteriorates, cov residual kev nyuaj siab tshaj tus nqi tso cai.
Tom qab muab cov kav dej tso rau hauv kev ua haujlwm, koj yuav tsum nruab lub boiler, yog tias muaj nyob hauv koj chav tsev. Ceg kav rau nws yuav tsum tau ua ua ntej, tab sis cov li qub qhib tam sim ntawd tom qab lub installation ntawm cov yeeb nkab, ntxiv rau cov ceg kav dej yog muffled.
Txiav steel kav
Kev teeb tsa cov kav hlau uas muaj txheej txheej galvanized tsis tuaj yeem ua los ntawm kev vuam, tab sis cov xov sib txuas tau siv ntau zaus. Qhov no yog vim qhov tseeb tias nyob rau hauv cov thermal loads tseem ceeb, cov hlau yuav hlawv tawm. Kev siv hom vuam tshwj xeeb thiab cov ntaub ntawv muab tub lim yuav daws tau qhov teeb meemtsuas yog ib feem xwb.
Thaum txhim kho cov kav dej steel rau dej thiab cua sov, cov ntsiab lus txuas nrog siv roj vuam. Txoj kev no tso cai rau koj kom ua tiav kev sib txuas zoo ntawm cov ntsiab lus. Rau qhov no, lub qhov thev naus laus zis raug txiav hauv cov yeeb nkab, thiab ib feem ntawm cov seam yog siv los ntawm sab hauv. Nyob rau hauv thawj theem, nws yog ib qhov tsim nyog los nqa tawm lub cim thiab txiav cov khoom nyob rau hauv cov chaw uas nws yog tsim nyog los ua docking. Thaum ntxuav cov ntug, nws raug nquahu kom siv lub log emery. Tom ntej no, cov npoo tau npaj, theem no yog muab lawv cov duab geometric uas yuav ua rau kom haum zoo.
Yog hais tias lub thickness ntawm cov yeeb nkab yog ntau tshaj 3 hli, ces rau arc vuam, lub kaum sab xis ntawm lub ces kaum yuav tsum siab tshaj 45 ° C. Hauv cov roj vuam, cov npoo yuav tsum tau yaj nrog cov nplaim taws ntawm qhov chaw uas qhov sib koom ua ke yuav tsum yog. Txhawm rau tshem tawm qhov khoob, cov hlau molten yuav tsum tau siv ntawm qhov kawg ntawm cov kav dej, sau qhov chaw nrog nws. Tom qab ntawd, qhov muab tub lim ib nrab txuas nrog.
Txhob cov kav dej
Kev txhim kho cov kav dej phwj tuaj muab rau ib qho kev nqes hav, uas yog qhov tsim nyog rau cov dej phwj tuaj. Yog tias qhov ntsuas no hloov ntawm 0.02 mus rau 0.03 °, ces qhov kev pom zoo ntawm cov dej phwj tuaj yuav yog kwv yees li 1 m / s. Nyob rau hauv lwm yam lus, rau txhua linear 'meter' nyob rau hauv ib tug kab rov tav nyob rau hauv cov yeeb nkab, nws yog tsim nyog los npaj ib txoj kab nqes ntawm qhov ntws ntawm 3 cm.
Txhim cov kav dej phwj tuaj, txoj kab uas hla tsis tshaj 5 cm, yuav tsum tau muab tso nrog txoj kab nqes ntawm 30 mm.txhua 'meter'. Yog tias cov kav dej uas siv txoj kab uas hla loj dua, ces txoj kab nqes tuaj yeem txo mus rau 20 hli ib kab 'meter'.
