Kugwiritsa ntchito ma flanges mu engineering ya mapaipi

Kuwotcherera kwa flanges lalikulu ndi gawo lomwe limagwirizanitsa mapaipi kwa wina ndi mzake, ogwirizana ndi mapeto a chitoliro, ndi kusindikizidwa ndi gasket pakati pawo. Kuwotcherera kwa flanges zazikulu, zomwe zimadziwikanso kuti kuwotcherera flanges, zimakhala ndi mabowo pazitsulo zowotcherera

Kulumikizana kolimba ndi mtundu wa chigawo chooneka ngati chimbale chomwe chimapezeka muumisiri wamapaipi.

Kuthamanga kwakukulu (150-200mm / s) kumafunika pakuwotcherera zitsulo ndi matenthedwe abwino a flanges. Ponena za zitsulo zomwezo, pali kutentha kwakukulu mu malo owonetserako chifukwa cha kuzizira kwa mgwirizano

M'pofunika kuwonjezera forging liwiro. Kuthamanga kwamphamvu kwa Fu Fu nthawi zambiri kumasonyezedwa ndi kukakamiza pagawo lililonse, ndiko kuti, mphamvu yamagetsi. Kukula kwa kuthamanga kwa forging kuyenera kuonetsetsa kuti zitsulo zamadzimadzi mkati mwa mawonekedwe zitha kutulutsidwa

Amadutsa ma deformation ena apulasitiki.

Chifukwa cha ntchito yake yochititsa chidwi, ma flanges akuluakulu amagwiritsidwa ntchito kwambiri mu mankhwala, zomangamanga, madzi, ngalande, mafuta, mafakitale opepuka komanso olemera, firiji, ukhondo, mapaipi, magetsi, ndi mafakitale opangira zinthu.

Cheng.

Pamene kuwotcherera flanges lalikulu, ngati pamwamba forging kuthamanga ndi kochepa kwambiri, mapindikidwe sikokwanira ndipo olowa mphamvu amachepetsa; Ngati kuthamanga kwapamwamba kwapamwamba kumakhala kolimba kwambiri, kusinthika kumakhala kwakukulu kwambiri, ndipo njere ya kristalo idzapindika komanso yolimba, zomwe zimachepetsanso kulimba kwa mgwirizano.

Kuthamanga kwa kuwala kowala kudzachititsa kuwonjezeka kutentha gradient, kotero pamene kuwotcherera zitsulo ndi matenthedwe madutsidwe wabwino (mkuwa, zotayidwa kasakaniza wazitsulo), flanges chitsulo wapadera amafuna lalikulu forging kuthamanga (150-400Mpa).

Kuwonjezera pamwamba ndondomeko magawo, kutentha preheating ndi preheating nthawi ayeneranso kuganizira preheating yowala malo kuwotcherera magawo. Kutentha kwa preheating kumasankhidwa kutengera gawo la mtanda ndi ntchito zakuthupi. Mukawotchera chitsulo chotsika mpweya,

700-900 madigiri.

Nthawi zambiri, kuwotcherera arc pamanja kumagwiritsidwa ntchito kuwotcherera ma flanges akulu, okhala ndi mizere yowotcherera ya arc komanso kuwotcha kosavuta komanso kutsika kwa m'mphepete, komwe sikungathe kuthetsedwa ngakhale ndi makina, zomwe zimapangitsa kuti pakhale mawonekedwe osawoneka bwino; 2. Chifukwa nthawi zambiri zimakhala zamtundu wina wazitsulo

Kuwotcherera kwakukulu, kusawongolera bwino kwa kuwotcherera, komanso kupezeka kosavuta kwa kuwotcherera kapena kusakwanira. Kwa ma flange akulu akulu, msoko wowotcherera uyenera kukonzedwa, kuti pasakhale chitsulo chocheperako pakati pa mphete yachitsulo ndi flange.
