Taw qhia
Dismantling Jointhais txog kev sib koom ua ke ntawm cov khoom siv hluav taws xob, uas yog cov khoom siv tshiab txuas nrog lub twj tso kua mis, lub valve, cov kav dej thiab lwm yam khoom siv nrog cov kav dej. Nws txuas nrog bolts los ua kom nws tag nrho thiab muaj qee qhov kev hloov pauv. Nws tau muab faib ua AY hom caj pas nthuav dav sib koom ua ke, AF hom flange xoob lub tes tsho nthuav dav sib koom ua ke, BF hom ib qho flange txwv kev nthuav dav sib koom ua ke, B2F hom ob lub flange txwv kev nthuav dav sib koom ua ke, BY hom caj pas xoob lub tes tsho txwv kev nthuav dav sib koom ua ke, CF ib qho flange quab yuam sib koom tes, C2F ob-flange fais fab kis sib txuas, thiab lwm yam.
Txhais
Lub dismantling sib koom (expansion sib koom) feem ntau yog siv rau kev txhim kho thiab kho. Nws raug kho raws li qhov loj me ntawm qhov chaw teeb tsa. Thaum lub sijhawm ua haujlwm, axial thrust tuaj yeem xa rov qab mus rau tag nrho cov kav dej. Qhov no tsis tsuas yog txhim kho kev ua haujlwm ntawm kev ua haujlwm, tab sis kuj tseem ua lub luag haujlwm hauv kev tiv thaiv lub twj tso kua mis, valve thiab lwm yam khoom siv hauv cov kav dej.

Cov lus qhia installation
Flange hom
Tom qab lub tes tsho xoob expansion sib koom ua ke yog ntsia rau ntawm cov yeeb nkab, zawm lub nplhaib elastic ntawm cov txiv ntseej. Nyob rau hauv qhov kev txiav txim ntawm cov txiv ntseej caj pas, qhov sib koom ua ke yog inclined rau ib leeg thiab nruj nreem nias ntawm lub nplhaib sab nraud ntawm cov yeeb nkab kom kaw thiab txuas. Thaum qhov kub hloov pauv, cov yeeb nkab tuaj yeem nthuav dav dawb hauv nruab nrab ntawm qhov sib koom ua ke. Thaum lub hauv paus dab dej, cov yeeb nkab tuaj yeem deflect thiab xyuas kom meej tias tsis muaj qhov xau hauv lub foob, yog li ua tiav lub hom phiaj ntawm kev them nyiaj tsis siv neeg.
Ib leeg flange txwv
Nws yog tsim rau kev sib txuas nrog flange thiab vuam nrog cov yeeb nkab tib lub sijhawm. Thaum lub sij hawm installation, kho lub installation ntev ntawm cov khoom thiab cov yeeb nkab los yog flange ntawm ob qho tib si xaus, zawm lub caj pas bolts diagonally thiab tusyees, thiab tom qab ntawd kho cov txiv ntseej, kom cov yeeb nkab tuaj yeem nthuav dav hauv qhov nthuav dav, xauv qhov nthuav dav, thiab xyuas kom muaj kev nyab xeeb ntawm cov yeeb nkab.
Ob chav flange txwv
Nws yog tsim rau kev sib txuas ntawm ob sab nrog flanges. Thaum lub sij hawm installation, kho qhov txuas ntev ntawm ob qhov kawg ntawm cov khoom, nruj lub caj pas bolts diagonally thiab tusyees, thiab tom qab ntawd kho cov txwv txwv, kom cov raj xa dej tuaj yeem nthuav dav, xauv qhov nthuav dav, thiab xyuas kom muaj kev nyab xeeb ntawm cov kav dej. .
Hom caj pas
Nws yog tsim rau ntsaws ob sab ntawm cov yeeb nkab tsis muaj vuam, nrog cov qauv tsim nyog, sealing thiab ceev thiab yooj yim installation.
nyhuv
Qhov tseem ceeb ntawm expansion pob qij txha nyob rau hauv pipeline installation. Vim hais tias qhov kub ntawm kev nthuav dav sib txuas sib txuas nrog cov kav dej loj lossis cov suab nrov txawv heev, kev siv ntawmexpansion pob qij txhayog ib qho kev tiv thaiv. Expansion pob qij txha yog cov khoom tshiab txuas cov twj, li qub, cov kav dej thiab lwm yam khoom siv nrog cov kav dej. Lawv txuas nrog tag nrho bolts kom lawv tag nrho, nrog rau qee qhov kev hloov pauv, uas yooj yim rau kev teeb tsa. Nws tuaj yeem tiv taus axial siab ntawm cov kav dej. Nyob rau hauv txoj kev no, nws tuaj yeem hloov kho raws li qhov loj me ntawm qhov chaw teeb tsa thaum lub sijhawm teeb tsa thiab kev saib xyuas, uas tsis yog tsuas yog txhim kho kev ua haujlwm zoo, tab sis kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv hauv cov kav dej xws li twj thiab li qub.
Txoj Cai Ua Haujlwm
Kev nthuav dav ntawm cov raj xa dej loj yog qhov loj, qhov kub thiab txias yog qhov siab, thiab qhov chaw siab yog muaj zog. Hauv kev tsim kho cov dej thiab cov dej ua haujlwm, lub hauv paus pob zeb nchuav los yog cov kav dej embedded, nyob rau hauv cov txheej txheem ntawm cov kav dej engineering no raug rau lub hauv paus kev daws teeb meem, cov khoom siv resonance, geological hloov, thiab kev hloov pauv hauv cov kav dej nruab nrab, cov kav dej xa dej. pib muaj kev ntxhov siab, deformed, twisted thiab puas, thiab cov kav dej embedded txawm tawg, uas ua rau muaj teeb meem loj rau chav tsev tsim kho. Txhawm rau kov yeej cov teeb meem no thiab ua kom muaj kev nyab xeeb ntawm cov raj xa dej, kev siv cov cuab yeej nthuav dav kev sib koom ua ke: nws tuaj yeem nthuav dav thiab nthuav dav axially nyob rau hauv ib qho kev sib tw kom kov yeej kev hloov pauv, misalignment, nthuav dav thiab nthuav dav ntawm ntau lub kaum sab xis ntawm cov kav dej. Cov yeeb nkab tuaj yeem nthuav dav dawb hauv cov khoom siv telescopic. Thaum qhov siab tshaj plaws nthuav dav tshaj, nws yuav ua lub luag haujlwm txwv. Yog li txhawm rau xyuas kom muaj kev nyab xeeb ntawm cov kav dej!
