1. Ndodo yowotcherera iyenera kukhala yowuma panthawi yogwiritsira ntchito.Mtundu wa calcium titanate udzauma pa 150'C kwa ola limodzi, ndipo mtundu wochepa wa haidrojeni udzauma pa 200-250 ℃ kwa ola limodzi (kuyanika sikungabwerezedwe kangapo, apo ayi khungu ndilosavuta. crack and peel off) kuteteza khungu la ndodo yowotcherera, mafuta omata ndi dothi lina, kuti apewe kuchulukitsa mpweya wowotcherera komanso kusokoneza mtundu wa weld.
2.Pakati pa kuwotcherera kwachitsulo chosapanga dzimbiri flangezopangira zitoliro, carbides ndi precipitated ndi Kutentha mobwerezabwereza, amene amachepetsa dzimbiri ndi makina katundu.
3.The anaumitsa American muyezo flange wa chrome zosapanga dzimbiri zitsulo flange chitoliro zovekera pambuyo kuwotcherera ndi lalikulu ndi zosavuta kusweka.Ngati mtundu womwewo wa chromium zosapanga dzimbiri elekitirodi (G202, G207) ntchito kuwotcherera, preheat pamwamba 300 ℃ ndi pang'onopang'ono kuzirala mankhwala mozungulira 700 ℃ pambuyo kuwotcherera chofunika.Ngati kuwotcherera sikungathe kuthandizidwa ndi kutentha kwapambuyo-weld, chitsulo chosapanga dzimbiri cha flange electrode (A107, A207) chidzasankhidwa.
4.Kwa flange yachitsulo chosapanga dzimbiri, kuchuluka koyenera kwa zinthu zokhazikika monga Ti, Nb ndi Mo zimawonjezeredwa kuti zithandizire kukana kwa dzimbiri ndi kuwotcherera.The weldability ndi bwino kuposa chrome zosapanga dzimbiri flange.Pamene mtundu womwewo wa chrome zosapanga dzimbiri zitsulo flange kuwotcherera ndodo (G302, G307) ntchito, preheating pamwamba 200 ℃ ndi kutentha mozungulira 800 ℃ pambuyo kuwotcherera zidzachitika.Ngati kuwotcherera sikungathe kutenthedwa, chitsulo chosapanga dzimbiri cha flange electrode (A107, A207) chidzasankhidwa.
5.Flange yachitsulo chosapanga dzimbiri zowotcherera mapaipi ndi matako kuwotcherera flange ndodo zabwino dzimbiri kukana ndi kukana mankhwala, ndipo chimagwiritsidwa ntchito mu mankhwala, feteleza, mafuta ndi makina kupanga.
6.Kuti muteteze kuwonongeka kwa diso ndi diso chifukwa cha kutentha kwa chivundikiro cha flange, kuwotcherera kwamakono sikuyenera kukhala kwakukulu, pafupifupi 20% kuchepera kuposa carbon steel electrode, arc sayenera kukhala yaitali kwambiri, ndipo kuziziritsa kwapakati-wosanjikiza sikuyenera kuchedwa, ndipo mkanda wopapatiza uyenera kukhala wokonda.
Mpweya wazitsulo wa carbon umagwiritsidwa ntchito mwapadera, choncho umafunika kuti ukhale wosalala, wovuta, wopondereza, wopondereza ndi zina za zipangizo.Ikhoza kugwiritsidwa ntchito pansi pa kupanikizika kwakukulu popanda kusokoneza.Chifukwa chitsulo cha kaboni chili ndi ma burrs ochepa, mphamvu yake yolimbana nayo ndi yaying'ono kwambiri, ndipo imatha kugwiritsidwa ntchito kwambiri pazida.
Kuphatikiza apo, ma flanges achitsulo cha kaboni amayenera kupangidwa motsatira mfundo zaku China kapena zofunikira zamakampani.Musagwiritse ntchito zipangizo zosayenerera kuzipanga.Pamene inu simungakhoze kudula ngodya pa kukula, izi njira mwayi adzatsogolera otsika ndi osayenera mankhwala, amene adzachititsa kulephera kwa dongosolo lonse French, ngakhale chifukwa chuma imfa ndi ovulala ndi ngozi zina khola.
Aliyense amene adamvapo za carbon steel flange amadziwa kuti kuponyera kwake kumakhala kovuta kwambiri.Pazinthu zake, chitsulo cha carbon ndi chosiyana ndi zitsulo zina, ndipo ntchito yake ndi yabwino kuposa yachitsulo.Choncho flange yabwino imapangidwa makamaka ndi chitsulo cha carbon, ndiko kuti, chotchedwa carbon steel flange.Kuphatikiza pa kaboni, chitsulo cha kaboni nthawi zambiri chimakhala ndi silicon, manganese, sulfure, phosphorous ndi zinthu zina, choncho zimakhala ndi zinthu zina.
Njira yoyezera ya carbon steel flange ndi ntchito yokonzekera musanayambe kuyeza idzafotokozedwa mwachidule ndi mkonzi.
1.Panthawi yoyezera, anthu atatu ayenera kukonzedwa, awiri amayeza, m'modzi akuyang'ana ndikulemba fomu.Ngati palibe chikhalidwe chogwiritsira ntchito caliper kunja ndi wolamulira wachitsulo, caliper ingagwiritsidwe ntchito ngati chida choyezera.Kuyeza ndi ntchito yosamala komanso chofunikira pakuyika zida.Kuyeza ndi zolemba zidzakonzedwa molondola, ndipo fomuyo idzadzazidwa mosamala ndi momveka bwino.Mu ntchito yeniyeni yoyezera.Kuti tigwirizane wina ndi mnzake, tiyenera kukhala ogwirizana ndi kugwiritsa ntchito mfundo zolondola.
2. Malingana ndi malo a flange yaikulu isanayesedwe, chithunzi chogwirizanitsa ndi chiwerengero cha flange chachikulu cha zipangizo chiyenera kujambulidwa poyamba, kuti chikhazikitsocho chikhoza kukhazikitsidwa molingana ndi njira ndi mfundo zofanana, komanso kugwiritsa ntchito bwino. zingadziwike.
3. Chifukwa awiri akunja a carbon steel flange akhoza kukhala osiyana, bowo cholakwika (chosiyana pakati) ndi makulidwe a gasket ndi osiyana, fixture kukonzedwa sayenera kusinthanitsa ndi mbali mpweya zitsulo flange, kotero kuyeza kukula ndi kuchuluka kwa gawo lililonse ndiye chinsinsi.Ixtere processing ndi kukhazikitsa.
Ma flanges a carbon steelamagwiritsidwa ntchito kwambiri tsiku ndi tsiku, ndipo kumwa sikuchedwa.Choncho, kukonzanso nthawi zonse kwa carbon steel flanges kumafunika kukhala ndi malamulo ofananirako kuti mukhale ndi mpweya wabwino wa carbon steel flanges momwe mungathere ndikuwongolera kuthamanga kwa ntchito.Apa tikugawana nanu magwiridwe antchito achitsulo chosapanga dzimbiri ndi ma flanges a carbon steel ndi zomwe ziyenera kukonzedwa:
1.Pamene mpweya wa carbon steel watsekedwa, pamakhalabe sing'anga yomwe yatsala mu thupi la valve, ndipo imanyamulanso kukakamizidwa komweko.Musanayambe kukonzanso mpweya wa carbon steel flange, tsekani valavu yotseka kutsogolo kwa carbon steel flange, tsegulani carbon steel flange kuti muwonjezedwe, ndikumasulani mphamvu ya mkati mwa thupi la valve.Ngati muli ndi flange yamagetsi ya carbon steel kapena valavu ya mpira wa pneumatic, mphamvu ndi mpweya ziyenera kuchotsedwa poyamba.
2.Kawirikawiri, kusindikiza kofewa kwa carbon steel flange kumagwiritsa ntchito tetrafluoroethylene (PTFE) ngati chinthu chosindikizira, ndipo malo osindikizira a valve olimba osindikizira mpira amapangidwa ndi zitsulo.Ngati kuli kofunikira kuyeretsa valavu ya mpira wa chitoliro, chisamaliro chiyenera kutengedwa kuti chiteteze kutayikira chifukwa cha kuwonongeka kwa mphete yosindikizira panthawi ya disassembly.
3.Pochotsa mpweya wa carbon steel flange, ma bolts ndi mtedza pa flange ayenera kukhazikitsidwa poyamba, ndiyeno mtedza wonse uyenera kumangirizidwa pang'ono ndikukhazikika.Ngati mtedza wina utakhazikika bwino mtedza wina usanakhazikitsidwe, gasket pamwamba pake imawonongeka kapena kusweka chifukwa cha kusanja kofanana pakati pa nkhope za flange, zomwe zimapangitsa kuti pakhale kutayikira kwapakatikati kuchokera kumagulu a valve flange.
4.Ngati valavu yatsukidwa, chosungunulira chomwe chimagwiritsidwa ntchito sichidzatsutsana ndi zigawo zomwe ziyenera kutsukidwa ndipo sizidzawonongeka.Ngati ndi carbon steel flange ya gasi, imatha kutsukidwa ndi mafuta.Zigawo zina zimatha kutsukidwa ndi madzi obwezeretsedwa.Pakuyeretsa, fumbi lotsalira, mafuta ndi zomangira zina ziyenera kutsukidwa kwathunthu.Ngati sangathe kutsukidwa ndi madzi oyera, akhoza kutsukidwa ndi mowa ndi zinthu zina zoyeretsera popanda kuwononga valavu ndi ziwalo.Mukamaliza kuyeretsa, dikirani kuti chotsukiracho chiwonongeke musanayambe kusonkhana.
5.Ngati kutayikira pang'ono kumapezeka pakulongedza panthawi yogwiritsira ntchito, mtedza wa valve ukhoza kumangirizidwa pang'ono mpaka kutaya kutayira.Musapitirize kumangitsa.
6.Musanagwiritse ntchito, payipi ndi gawo losefukira la thupi la valve liyenera kutsukidwa ndi madzi kuti zitsulo zotsalira zachitsulo ndi zina zambiri zisalowe mkati mwa thupi la valve.
Komanso, ngati mpweya zitsulo flange anaikidwa panja kwa nthawi yaitali, ndipo palibe miyeso kuopa madzi, izo zimabweretsa dzimbiri matupi valavu ndi zigawo zikuluzikulu.Mwanjira imeneyi, m'pofunika kuyesa kukhazikika kwa carbon steel flange panthawi yogwiritsira ntchito.
