Zinthu zomwe zimakhudza digiri ya kugwiritsa ntchito flange

Pankhani wamba coarseness waflanges, makalasi osiyanasiyana zitsulo ndi njira zokhotakhota zosiyanasiyana ndi madigiri osiyana kuchepetsa kutopa, monga kuchepa digiriotentha koyilo flangesndi yaying'ono kuposaotentha koyilo flanges. Zoyeserera zikuwonetsa kuti plating ya cadmium imatha kukulitsa kuchuluka kwa kutopaflange. Theflangeogwira ntchito pansi pa malo otentha kwambiri ayenera kuganizira kugwiritsa ntchito zitsulo zosagwira kutentha.

Pali mgwirizano wina pakati pa zokolola mphamvu yaflangendi kuchepetsa kutopa. Nthawi zambiri, mphamvu zokolola zakuthupi zimakhala zapamwamba kwambiri, mphamvu za kutopa zimakwera. Choncho, kutopa mphamvu oyendayendaflangeziyenera kutsimikiziridwa ndi mphamvu zokolola za oyendayendaflangezakuthupi, kapena zinthu zomwe zili ndi chiŵerengero chapamwamba cha mphamvu zokolola ndi mphamvu zamakokedwe ziyenera kusankhidwa. Choncho, muyezo zotsatira ayenera kuganiziridwa powerengera kutopa mphamvu ya flange.
Chikoka cha dzimbiri pa kutopa mphamvuflangesizingokhudzana ndi kuchuluka kwa nthawi yomwe flange imayikidwa pa katundu wosinthika, komanso yokhudzana ndi kuchuluka kwa moyo wogwira ntchito. Pamene kuuma kwa pamwamba kumawonjezeka, kuchepetsa kutopa kumachepa. Choncho, moyo wa opareshoni uyenera kuganiziridwa pokonzekera ndi kuwerengera ma flanges omwe akhudzidwa ndi dzimbiri.
Kukumana kulipo pakuphatikizidwa ndikupanikizika pamwamba pa gwero, kungayambitse kuphatikizika ndi mawonekedwe a masanjidwewo pakati pa ming'alu ya kutopa nthawi isanakwane, kuchuluka kwa zinthu zomwe zimakhudzidwa,flangesmuyezo wa mitundu yonse ya ukadaulo wozizira komanso wotentha wogwirira ntchito, kukulitsa kuthekera kwa zolakwika zapamtunda, m'pamenenso kuthekera kwazifukwa izi kumabweretsa kutopa. Zing'onozing'ono roughness ya zinthu pamwamba, ang'onoang'ono kupsinjika maganizo convergence, ndi apamwamba kutopa mphamvu.
Kutopa kwachitsulo kumawonjezeka pamene kutentha kuli kotsika kusiyana ndi kutentha kwa chipinda. Kutopa kwa chitsulo cha carbon kumatsika kuchokera ku firiji kufika pa 120 ℃, kumakwera kuchoka pa 120 ℃ kufika pa 350 ℃, ndipo kumatsika kutentha kukafika pa 350 ℃. Palibe malire otopa pa kutentha kwakukulu, kugaya, kuthamanga kwamphamvu, kuwombera kuphulika ndi kugudubuza kwa zinthu zakuthupi.
Flangepamwamba chikhalidwe Kupanikizika kwakukulu kumapangidwa makamaka pamwamba paflangezakuthupi, kotero pamwamba khalidwe la flange ali ndi chikoka chachikulu pa mphamvu kutopa. Pamene zikuwononga sing'angaflangeimagwira ntchito m'malo owononga, imakhala gwero la kutopa chifukwa cha dzimbiri pamtunda kapena dzimbiri la malire a tirigu pamtunda. Pansi pa kupsinjika kosinthika, pang'onopang'ono idzakula ndikuyambitsa kusweka. Chifukwa chitsulo otentha koyilo flange ndi kutentha mankhwala kutentha, chifukwa makutidwe ndi okosijeni waflangezinthu pamwamba amakhala coarse ndi decarburization chodabwitsa, kuti achepetse kutopa mphamvu yaflange.
