Installation Method ntawm Chrome Moly Flanges
Kev npaj theem
• Kev kuaj xyuas cov ntaub ntawv: xyuas kom meej tias tag nrho cov ntaub ntawv xws li chrome moly flanges, bolts, gaskets, thiab lwm yam yog raws li tus qauv tsim thiab tsis muaj kev puas tsuaj lossis tsis zoo.
• Kev ua haujlwm tu: Ntxuav lub sealing nto ntawm flange thiab cov yeeb nkab txuas cheeb tsam kom ntseeg tau tias tsis muaj roj, av, impurities, thiab lwm yam, kom tsis txhob cuam tshuam cov sealing nyhuv.
Flange taub qab Joint
• Alignment: Teem lub sealing nto ntawm ob lub flanges kom ntseeg tau tias qhov nruab nrab ntawm cov flange pob qij txha yog tsawg dua 1.5mm, qhov sealing nto tsis ntau tshaj 0.8mm, lub qhov ntsia hlau yog sib dhos, thiab qhov offset nruab nrab ntawm lub qhov tsis ntau tshaj 3 hli.
• Kev tswj qhov sib txawv: Ua ntej zawm lub bolts, qhov sib txawv ntawm qhov sib khi ntawm lub flanges yuav tsum tsis pub ntau tshaj 2 npaug ntawm lub thickness ntawm lub gasket, thiab nws yuav tsum tsis txhob zaum nrog kev pab los ntawm cov cuab yeej pab ntxiv, thiab yuav tsum tsis txhob muab cov bolts. yuav tsum nruj los ntawm txoj kev nruj nruj kom kho qhov sib nrug ntawm flanges los yog tshem tawm cov deflection ntawm flange pob qij txha.
Gasket Installation
• Kev xaiv Gasket: Xaiv cov gaskets uas phim lub flange loj thiab xyuas kom meej tias cov khoom thiab kev ua tau zoo ntawm gaskets raws li tus qauv tsim.
• Gasket Installation: Muab lub gasket nyob nruab nrab ntawm ob lub flanges kom ntseeg tau tias lub gasket yog coaxial nrog flanges thiab tiv thaiv lub gasket los ntawm kev thaiv txoj kev tawm. Txoj kev tsim nyog yuav tsum tau siv los tso lub gasket thaum lub sijhawm teeb tsa. Tsis txhob siv cov nplaum nplaum los kho lub gasket, lossis siv roj ntawm qhov xav tau (tshwj tsis yog lub chaw tsim khoom gasket muaj cov cai tshwj xeeb).
Bolt Fastening
• Fastening sequence: Fastening the flanges raws li lub hauv paus ntsiab lus ntawm symmetrical fastening, teem lub fastening sequence naj npawb thiab xa mus rau cov duab kos.
• Ua ntej fastening: Muab lub gasket nrog 4 screws ntawm 1, 2, 3 thiab 4 kom paub meej tias qhov nruab nrab ntawm cov ntaub qhwv gasket nyob rau hauv lub ntug ntawm lub flange. Tom qab ntawd tes tuav cov ntsia hlau qhov chaw, ua raws li los ntawm kev ntxig rau lwm cov stud screws thiab ceev lawv kom sib npaug ntawm cov load. Xyuas kom tseeb tias tsawg kawg 2 threads raug nthuav tawm ntawm txhua qhov kawg ntawm cov txiv ntoo.
• Kev nruj nruj: Raws li cov khoom siv ntawm qhov chaw thiab flange tej yam kev mob, raws li kev zawm ntawm lub voj voog rau kev suav, tsim qauv tsim nyog ntawm tus naj npawb ntawm cov sij hawm (tsawg kawg 3 zaug) thiab txhua lub sij hawm nruj load (lub zog. los yog torque). Lub load yuav tsum nruj me ntsis mus rau loj (xws li 50%, 80%, 100% increment), thiab yuav tsum tsis txhob yuav loaded ceev los yog loj heev kom tsis txhob gasket foob tsis ua hauj lwm.
• Thaum kawg zawm: Thaum kawg nruj tag nrho cov screws nyob rau hauv clockwise los yog counterclockwise kev txiav txim ntawm 100% load ( quab yuam los yog torque). Yog tias siv lub torque wrench, tus nqi torque yuav tsum tau sau tseg rau yav tom ntej siv.
Kev Tshawb Fawb Thiab Cov Ntaub Ntawv
• Kos Sealing: Tom qab kev teeb tsa, xyuas qhov kev sib khi ntawm cov flange pob qij txha kom paub tseeb tias tsis muaj qhov xau.
• Cov ntaub ntawv sau tseg: Sau cov ntaub ntawv tseem ceeb thaum lub sijhawm teeb tsa, xws li kev sib tw nruj, tus naj npawb ntawm lub sijhawm nruj, tus nqi torque, thiab lwm yam, rau kev kho thiab kho yav tom ntej.
Ceev faj
• Thaum lub sij hawm installation, tsis txhob puas flanges, bolts, gaskets thiab lwm yam ntaub ntawv.
• Thaum fastening lub bolts, xyuas kom meej tias cov bolts yog perpendicular mus rau lub flange thiab kis tau dawb do los ntawm cov ntsia liaj qhov rooj qhov, thiab cov txiv ntseej yog tiaj tus rau sab nraum qab ntawm flange.
• Yog tias qhov sib txawv ntawm qhov sib txawv ntawm flange sib koom ua ke tsis muaj qhov tshwj xeeb, nws yuav tsum raug kho ua ntej lub gasket loaded.
• Lub installation ntawm li qub thiab lwm yam khoom siv yuav tsum ua raws li cov qauv tsim thiab cov qauv tsim kom ntseeg tau tias cov kev taw qhia kev teeb tsa yog qhov tseeb thiab lub foob zoo.
