Cov txheej txheem kev teeb tsa
Kev soj ntsuam ua ntej thiab ua ntej
Kev Tshawb Fawb: Txheeb xyuas qhov nominal siab, tus qauv flange (GB / ANSI / DIN), txheej kab ntawm cov yeeb nkab sib xws, thiab cov khoom siv gasket (EPDM rau cov dej haus, NBR rau cov roj tawm).
Ntxuav: Polish cov yeeb nkab kawg kom ua tiav; tshem tawm burrs, weld hlaws, xeb thiab roj paug. Khaws lub flange sealing ntsej muag thiab roj hmab gasket kom huv si, tsis muaj grit thiab khib nyiab.
Kos cov kab qhov tob tob ntawm cov yeeb nkab kom tsis txhob muaj kev ntxig ntau dhau uas kaw qhov haum, thiab khaws cov nyiaj them poob haujlwm (feem ntau 5-10 hli).
Pre-assembly ntawm Cheebtsam
Xaub lub nplhaib compression (gland), roj hmab gasket thiab adapter lub cev mus rau hauv cov yeeb nkab ua ntu zus. Tsis txhob siv cov roj cav lossis roj rau EPDM gaskets rau cov dej haus. Khoom noj khoom haus qib tshwj xeeb lubricant los yog dej xab npum yuav siv tau rau lubrication los tiv thaiv kev sib tw los yog dov ntawm lub gasket.
Centering thiab Alignment
Teem lub adapter flange nrog mating flange ntawm lub valve lossis khoom siv. Ntxig ob qhov chaw bolts rau kev txhawb nqa ib ntus thiab qhov chaw kom ntseeg tau tias cov yeeb nkab concentricity. Tsis txhob yuam kev sib koom ua ke nyob rau hauv strain.
Staged Diagonal Tightening (tseem ceeb)
Rau flange kev twb kev txuas bolts: Tighten nyob rau hauv kab pheeb ces kaum / lub hnub qub qauv nyob rau hauv ntau dhau, ntawm 30% torque → 60% torque → tag nrho torque. Tsis txhob nruj bolts ntawm ib sab ib zaug.
Rau cov yeeb nkab kawg compression bolts: Tighten tusyees nyob rau hauv kab pheeb ces kaum ib yam nkaus, yog li qhov sib txawv nyob ib ncig ntawm lub voj voog tseem tsis sib xws los tiv thaiv kev hnav tsis sib xws thiab hauv zos to.
Rau PE cov kav dej yas, cov qauv nrog lub nplhaib thawb rau rub tawm yog nyiam kom tsis txhob muaj kev puas tsuaj nyob rau hauv siab.
Kev Xeem Siab thiab Txais
Tom qab ua tiav ntawm kev teeb tsa, ua qhov ntsuas hydrostatic lossis huab cua nruj. Tuav lub siab thiab tshuaj xyuas qhov sib koom ua ke kom pom. Lub installation tsuas yog txais yog tias lub siab ua tau raws li qhov yuav tsum tau ua thiab tsis muaj qhov xau tshwm sim.
Daim ntawv thov Scenario
kev lag luam-ua
Cov dej hauv nroog thiab cov dej ntws tawm, cov dej ua haujlwm thiab cov dej phwj tuaj kho dej: Txuas PE / cov kav hlau txuas rau lub rooj vag li qub, npauj npaim li qub, cov twj tso kua dej, cov ntsuas dej thiab cov ntsuas dej ntws. Siv rau kev kho thaum muaj xwm txheej ceev thiab hloov yeeb nkab, nrog rau flange kev sib txuas ntawm cov kav dej tshiab thiab qub. Haum rau kev pabcuam dej haus (EPDM gaskets).
01
Kev lag luam siab
HVAC thiab cov kav hluav taws tiv thaiv hluav taws: kev hloov pauv sai rau cov kav dej steel thiab cov kav dej galvanized, yooj yim rau disassembly thiab txij nkawm tom qab theem.
02
Kev lag luam siab
Tshuaj, roj & roj thiab chaw nres tsheb: Flange hloov dua siab tshiab rau cov txheej txheem pipelines. NBR thiab lwm yam roj-resistant seals raug saws; pull-out resistant hom yog siv rau hauv cov cheeb tsam uas muaj kev sib haum xeeb hauv lub hauv paus.
03
Cov khoom zoo meej system
Agricultural irrigation, seawater desalination thiab marine daim ntaub ntawv: Kev hloov pauv ntawm cov kav dej ntawm cov khoom sib txawv kom txo tau txoj haujlwm vuam.
04
Kev pabcuam zoo tom qab muag
Retrofit thiab kho cov phiaj xwm xwm txheej ceev: nrawm ntxiv flange kev sib txuas ntawm cov kav dej qub yam tsis muaj flanges uas twb muaj lawm, txo cov dej ntws tawm ntev.
05
Shanxi Jintai Hongye Casting thiab Forging Machinery Co., Ltd., nyob rau hauv Shanxi xeev, Suav teb, yog ib tug ua chaw tsim tshuaj paus ntawm ductile hlau yeeb fittings, kav, ntau yam li qub, thiab manhole npog. Peb muaj automated ntau lawm kab thiab ib tug paub ntau lawm technology pab neeg los muab koj nrog kev thiab hloov tau customized daws.
