Dismantling pob qij txha, tseem hu ua fais fab kis pob qij txha los yog quab yuam kis tau tus mob pob qij txha, yog txawv los ntawm ib tug flange fais fab kis pob qij txha, ob flange fais fab kis pob qij txha, thiab dismantling ob flange fais fab kis pob qij txha, tab sis lawv txoj kev sib txuas tsis zoo ib yam.
1. Ib leeg flange quab yuam kis tau tus mob pob qij txhayog tsim rau kev sib txuas ntawm ib sab rau lub flange thiab welding rau lwm sab rau lub raj xa dej. Thaum lub sij hawm installation, kho lub installation ntev ntawm ob qhov kawg ntawm cov khoom thiab cov kav dej los yog flange. Tom qab kev txhim kho thiab vuam ua tiav, zawm lub caj pas bolts diagonally thiab tusyees los ua ib qho, nrog rau qee qhov kev hloov pauv. Txhawm rau txhim kho kev teeb tsa thiab kev saib xyuas, kev hloov kho yuav raug ua raws li qhov ntev ntawm qhov chaw. Thaum ua haujlwm, axial thrust tuaj yeem xa mus rau tag nrho cov kav dej.
2. Ob lub flange fais fab kis tau tus mob yog tsim los ntawm cov khoom tseem ceeb xws li lub cev, sealing nplhaib, caj pas, thiab expansion luv yeeb nkab. Haum rau cov kav dej txuas nrog flanges ntawm ob sab. Thaum lub sij hawm installation, kho lub installation ntev ntawm ob kawg ntawm cov khoom thiab cov flange. Tighten lub caj pas bolts diagonally thiab tusyees ua ib tug tag nrho nrog ib tug tej yam kev hloov. Thaum yooj yim rau kev teeb tsa thiab kev saib xyuas, kev hloov kho yuav raug ua raws li qhov ntev ntawm qhov chaw. Thaum lub sijhawm ua haujlwm, qhov kev tiv thaiv axial tuaj yeem xa mus rau tag nrho cov kav dej.
Qhov zoo: Yooj yim thiab yooj yim installation, yooj yim valve installation
Nta: Ibflangethiab ib txoj kev vuam
3. Covdetachable ob flange quab yuam hloov kev sib koom tesyog composed ntawm xoob flange expansion pob qij txha, luv yeeb nkab flanges, fais fab kis screws, thiab lwm yam khoom. Nws muaj peev xwm kis tau lub siab thiab thrust (qhov muag tsis pom phaj quab yuam) ntawm qhov txuas txuas thiab them nyiaj rau kev teeb tsa cov kav dej, tab sis tsis tuaj yeem nqus axial hloov chaw. Feem ntau yog siv rau xoob kev sib txuas ntawm cov khoom siv xws li twj thiab li qub.
Tsis tas li ntawd, lub zog xa hluav taws xob sib txuas tuaj yeem muab faib ua ib nrab xaim hluav taws xob sib txuas sib txuas thiab tag nrho cov xaim hluav taws xob sib txuas sib txuas thaum kho.
Tus nqi ntawm ib nrab xaim hluav taws xob sib txuas sib txuas yog pheej yig dua, uas yog, lub qhov flange tau teeb tsa nrog txwv txoj hauj lwm xov hlau nyias nyias;
Tus nqi ntawm tag nrho cov xaim xaim sib txuas yog kim dua, uas yog, txhua qhov flange muaj bolts.
