Kodi ndiyenera kuchita chiyani ngati nditakumana ndi vuto losalumikizana komanso losalowa mkati mwa valve nditagwiritsa ntchito welding?

1. Makhalidwe abwino a chilema
Kusasakanikirana kumatanthauza chochitika chakuti chitsulo chosungunula sichimasungunuka kwathunthu ndikugwirizana ndi chitsulo choyambira kapena pakati pa zigawo za chitsulo chosungunula.
Kulephera kulowa kumatanthauza kuti muzu wa cholumikizira cholumikizidwa sunalowe kwathunthu.
Kusalumikizana ndi kusalowa konse kudzachepetsa malo ogwirira ntchito bwino a weld, kuchepetsa mphamvu ndi kulimba.
2. Zoyambitsa
Chifukwa cha kusasakanikirana: mphamvu yolumikizira ndi yaying'ono kwambiri kapena liwiro lolumikizira ndi lachangu kwambiri, zomwe zimapangitsa kuti kutentha kusakwane, ndipo chitsulo choyambira ndi chitsulo chodzaza sizingasungunuke kwathunthu. Ngodya ya groove ndi yaying'ono kwambiri, mpata ndi wopapatiza kwambiri kapena m'mphepete mopanda mawonekedwe ndi waukulu kwambiri, kotero kuti arc singathe kulowa mkati mwa muzu wa groove panthawi yolumikizira, zomwe zimapangitsa kuti chitsulo choyambira ndi chitsulo cholumikizira zisagwirizane. Pali zinthu zodetsedwa monga utoto wa mafuta ndi dzimbiri pamwamba pa weldment, zomwe zimakhudza kusungunuka ndi kusakanikirana kwa chitsulo. Kugwira ntchito molakwika, monga ngodya yolakwika ya electrode, njira yosayenera yonyamulira bar, ndi zina zotero, zimapangitsa arc kuchoka m'mphepete mwa groove kapena kulephera kuphimba bwino groove.
Zomwe zimayambitsa kusalowa: Zofanana ndi zifukwa zina zosalumikizana, monga mphamvu yolowetsera yaying'ono kwambiri, liwiro lolowetsera mofulumira kwambiri, kukula kosayenera kwa groove, ndi zina zotero. Mukalowetsera, arc imakhala yayitali kwambiri, ndipo kutentha kwa arc kumafalikira, zomwe zimapangitsa kuti chitsulo cha mizu chisungunuke bwino. Mpata wosonkhana wa weldment ndi wofanana, ndipo n'zosavuta kuti pasakhale kulowa kwa weld mu gawo lomwe lili ndi mpata waukulu.
3. Kukonza
Kukonza kosasakanikirana: Pa malo osasakanikirana, gudumu lopukusira lingagwiritsidwe ntchito kupukuta magawo osasakanikirana kenako n’kuwotchereranso. Mukawotchereranso, magawo a njira yowotcherera ayenera kusinthidwa kuti atsimikizire kuti kutentha kokwanira kusungunula chitsulo choyambira ndi chitsulo chodzaza. Pa malo osasakanikirana mkati, nthawi zambiri ndikofunikira kugwiritsa ntchito njira zoyesera zosawononga kuti mudziwe komwe kulibe kusakanikirana, kenako gwiritsani ntchito njira zoboola kaboni kapena njira zomangira kuti muchotse magawo osasakanikirana, kenako ndikuchita kukonza kuwotcherera. Mukakonza kuwotcherera, samalani kutsuka mtsempha, wongolerani ngodya yowotcherera ndi njira yonyamulira bala.
Kukonza kosalowa: Ngati kuya kwa kulowa kosalowa sikuli kozama, gawo losalowa likhoza kuchotsedwa pogaya ndi gudumu logaya, kenako kukonza kuwotcherera. Pakuya kwakukulu, nthawi zambiri pamafunika kugwiritsa ntchito choboola cha carbon arc kapena machining kuti muchotse ziwalo zonse za kulowa kwa weld mpaka chitsulo chabwino chitawonekera, kenako kukonza kuwotcherera. Pokonza kuwotcherera, mphamvu yowotcherera, mphamvu yamagetsi ndi liwiro la kuwotcherera ziyenera kulamulidwa mosamala kuti muzu ulowe mokwanira.
4. Kukonza zinthu zowotcherera
Kawirikawiri, zipangizo zowotcherera zomwe zili zofanana kapena zofanana ndi maziko a valavu ziyenera kusankhidwa. Mwachitsanzo, pa mavalavu achitsulo cha kaboni wamba, ndodo zowotcherera za E4303 (J422) zitha kusankhidwa; Pa mavalavu achitsulo chosapanga dzimbiri, ndodo zowotcherera zachitsulo chosapanga dzimbiri zofanana zimatha kusankhidwa malinga ndi zipangizo zinazake, monga ndodo zowotcherera za A102 zachitsulo chosapanga dzimbiri 304mavavu, Ndodo zolumikizira za A022 zachitsulo chosapanga dzimbiri cha 316Lmavavu, ndi zina zotero.

Tianjin Tanggu Madzi-Chisindikizo Valve Co., Ltd makamaka kupangavalavu ya gulugufe, valavu ya chipata,Chotsukira cha Y, valavu yolinganiza, valavu yowunikira, ndi zina zotero.
