Feem ntau, tom qab siv ob peb xyoos, phab ntsa sab hauv ntawm cov yeeb nkab hlau yuav ntxhib vim muaj xeb loj, thiab qhov tsis kam ntws nce ntxiv, yog li ntawd txo qhov muaj peev xwm xa dej ntau heev; nyob rau hauv qhov kub ua haujlwm ntawm 70 ℃ thiab siab ntawm 0.82MPa, cov yeeb nkab tuaj yeem siv tau zoo rau ntau tshaj 50 xyoo;

5. Kev tiv thaiv zoo, qhov nkag ntawm PE-RT yeeb nkab hloov pauv nrog qhov hloov pauv ntawm qhov kub thiab txias, PE-RT tsis xav tau phaj sib txuas vim yog cov khoom siv raw tshwj xeeb, thaum tsim tom qab tsim khoom, qhov nkag mus tas li;

6. Tsis muaj cov tshuaj lom ntxiv rau hauv cov txheej txheem tsim cov yeeb nkab, phab ntsa sab hauv du, tsis muaj scaling, tsis muaj kab mob loj hlob, tuaj yeem siv tau zoo hauv kev xa dej haus thiab lwm qhov chaw;

7. Kev ua haujlwm zoo ntawm kev ua kom sov, kev ua kom sov yog 0.4W / (m • K), tuaj yeem txuag tau ntau lub zog hauv kev siv cua sov, yog li PE-RT tuaj yeem ua si tag nrho rau nws cov yam ntxwv zoo heev hauv kev ua kom sov;

8. Kev Txuas Tau: Tom qab lub raj xa dej puas lawm, nws tuaj yeem txuas nrog kev sib txuas kub lossis kev sib txuas hluav taws xob

Cov yeeb nkab tiv thaiv MPP cable muaj kev tiv thaiv ib puag ncig, kev noj qab haus huv, kev kaw, tiv thaiv xeb, poob siab, zoo, tus nqi qis, kev tsim kho yooj yim thiab lwm yam zoo. Nws muaj txiaj ntsig zoo rau kev lag luam thiab kev sib raug zoo hauv kev siv hluav taws xob, thiab muaj kev cia siab dav.

Cov hauv qab no yog cov txheej txheem vuam tseem ceeb thiab cov ntsiab lus ua haujlwm ntawm MPP fais fab threading yeeb nkab:

Kev vuam kub yaj (feem ntau siv)

1. Kev Npaj
Ntxuav qhov kawg ntawm cov yeeb nkab thiab siv cawv kom tshem tawm cov roj, cov dej noo thiab cov khoom tsis huv.
Tshawb xyuas lub zog ntawm lub tshuab vuam, roj hydraulic thiab lub phaj cua sov, thiab teeb tsa qhov kub rau 200-225 ℃ (nce kom tsim nyog thaum qhov kub qis).
Tom qab cov yeeb nkab raug kho, lub ntsej muag kawg yog milled kom ntseeg tau tias qhov tsis sib xws yog ≤ 10% ntawm cov yeeb nkab phab ntsa tuab.

2. Kev ua kom sov thiab chaw nres nkoj
Tom qab lub phaj cua sov mus txog qhov kub uas xav tau, sai sai muab cov yeeb nkab tso rau hauv thiab nias nws kom tsim tau ib lub flange ntawm qhov kawg (qhov siab ntawm lub flange yuav tsum ua tau raws li qhov kub uas xav tau).
Tom qab tswj tau qhov siab thiab nqus cua sov tau 2 feeb, lub phaj raug tshem tawm sai sai thiab cov yeeb nkab kawg raug sib txuas tsis muaj kev tig hauv lub sijhawm luv luv (feem ntau yog 5-10 vib nas this).
Tom qab koj muab lub thawv tso rau hauv qhov chaw nres nkoj, nias kom ruaj khov thiab cia kom txias li qub li ntawm ≥ 20 feeb. Txwv tsis pub yuam kom txias.

Kev sib txuas hluav taws xob

1. Kev sib phim ntawm cov txheej txheem
Luam theej daim barcode ntawm lub tes tsho hluav taws xob fusion kom tau txais cov txheej txheem ntawm lub tshuab vuam (voltage, lub sijhawm).
Tshem tawm cov khoom tsis huv ntawm qhov sib koom ua ke thiab xyuas kom meej tias qhov sib txawv ntawm cov yeeb nkab thiab lub tes tsho yog sib xws.

2. Cov txheej txheem vuam
Pib lub tshuab vuam thiab saib xyuas qhov hluav taws xob hloov pauv thoob plaws hauv cov txheej txheem. Cov txheej txheem xaus thaum lub teeb qhia txog qhov xwm txheej yaj ploj mus.
Tsis txhob txav cov yeeb nkab thaum lub sijhawm txias.

Lwm txoj kev sib txuas

1. Kev sib txuas ntawm qhov (socket)
Lub foob roj hmab yuav tsum tau muab tso rau qhov chaw kom raug thiab siv rab mallet los ntaus rau hauv qhov chaw kom tiv thaiv kev puas tsuaj.
Tshawb xyuas qhov sealing tsis tu ncua, tsim nyog rau cov xwm txheej siab qis.

2. Kev sib txuas ntawm flange
Cov bolts yuav tsum tau nruj nreem thiab sib npaug, thiab cov hlau sib phim yuav tsum tau kub-dip galvanized rau kev tiv thaiv xeb.
Haum rau cov kav dej loj uas yuav tsum tau rhuav tshem ntau zaus.

Cov kev ceev faj dav dav

Kev tswj hwm ib puag ncig: Thaum qhov kub thiab txias hauv qab -5 ℃ lossis muaj cua hlob, yuav tsum muaj kev tiv thaiv thermal rwb thaiv tsev.

Kev tshuaj xyuas zoo: Tom qab vuam lawm, xyuas seb qhov vuam tiaj tiaj li cas kom pom tias puas muaj npuas lossis tawg; ua qhov kev sim siab yog tias tsim nyog.

Kev ua haujlwm zoo: Tsis txhob ntswj thaum lub sijhawm vuam kub, thiab cov neeg ua haujlwm xav tau kev cob qhia tshaj lij
