Chidziwitso chaukadaulo waukadaulo ndi njira yopangira ma flange wowotcherera matako ndi flange yowotcherera

Matako-kuwotcherera flange ndi chimodzi mwa flanges, amene amanena za flange ndi khosi ndi kuzungulira chitoliro kusintha ndi chikugwirizana ndi chitoliro ndi matako kuwotcherera. Chifukwa kutalika kwa khosi kumatha kugawidwakhosi matako kuwotcherera flangendikhosi lathyathyathya kuwotcherera flange.
Flanges zowotcherera matako zimagwiritsidwa ntchito kwambiri chifukwa sizili zophweka kupunduka, zosindikizidwa bwino, zimagwiritsidwa ntchito kwambiri, zimakhala ndi zofunikira zokhazikika komanso zokhazikika komanso kusintha kwapang'onopang'ono kwa matako.
Ndi chitukuko cha kupanga mapaipi aatali, flange yotchinga matako yakhala gawo lofunikira pakuyesa kukakamiza kwa mapaipi. Kuyesa kusanachitike komanso pambuyo pake, gawo lililonse la payipi liyenera kusesedwa mu mpira, pafupipafupi 4-5. Makamaka pambuyo poyesa kukakamiza, zimakhala zovuta kuyeretsa madzi mupaipi, ndipo nthawi yoyeretsa idzawonjezeka.
Flat kuwotcherera flange ndi mtundu wina waflange. Amagwiritsidwa ntchito kwambiri komanso amalimbikitsidwa m'makina opangira makina, ndipo adalandira matamando ndi kuyanjidwa ndi ogwiritsa ntchito ambiri.
Malo akuluakulu ogwiritsira ntchito flange yowotcherera ndi abwino, ndipo mtengo wake wowotcherera ndi momwe zimagwirira ntchito ziyenera kutsimikiziridwa malinga ndi momwe zilili. Flange kupanga ndi yosavuta komanso mtengo wotsika, koma kuwotcherera ntchito ndi lalikulu, ma elekitirodi mowa ndi lalikulu, ndipo sangathe kupirira kutentha, kuthamanga, kupindika mobwerezabwereza ndi kutentha kusinthasintha. Amagwiritsidwa ntchito pa mapaipi okhala ndi PN ≤ 2.5MPa, kutentha kwabwino, ndi kutentha kwa ntchito t ≤ 0 ℃.
Wina ndi kuwotcherera chowotcherera chakunja pakati pa flange ndi chitoliro, komanso kuwotcherera chitoliro chomwe chalowetsedwa mu flange. Chitoliro ndi nkhope ya flange ziyenera kuwotcherera malinga ndi zofunikira za msonkhano. Dziwani kuti nkhope ya flange singawonongeke panthawi yowotcherera, apo ayi kusindikiza sikuli bwino. Njira yowotcherera ndi kuwotcherera kwa arc, ndipo kuwotcherera komwe kumafunidwa ndi njira yowotcherera kungagwiritsidwe ntchito.

Ubwino
Flange yowotcherera matako imakhala ndi kapangidwe koyenera, mphamvu yayikulu komanso kukhazikika, imatha kupirira kutentha kwambiri komanso kuthamanga kwambiri, kupindika mobwerezabwereza komanso kusinthasintha kwa kutentha, kusindikiza bwino, ndipo sikophweka kupunduka. Amagwiritsidwa ntchito kwambiri pamapaipi okhala ndi kuthamanga kwakukulu kapena kusinthasintha kwa kutentha kapena kutentha kwambiri, kuthamanga kwambiri ndi mapaipi otsika kutentha. M'mabanja, chitoliro m'mimba mwake ndi chochepa, ndipo ndi otsika kuthamanga, ndi kugwirizana kwa matako kuwotcherera flange ndi wosaoneka. M'chipinda chowotchera kapena malo opangira, pali mapaipi ndi zida zolumikizidwa ndi ma flanges owotcherera matako kulikonse.

Kodi njira yopangira matako kuwotcherera flange ndi iti?
1. Kupanga chosowekacho kukhala lalikulu billet, kenako ozizira kupinda mu arc gawo, annealing pambuyo kutentha kutentha, ndiyeno kusonkhanitsa mu bwalo lonse pa lathe ofukula kuti akonze mawonekedwe ndi kukula kwake;
2. Chinthu choyamba ndi kunyamula kupita ku malo omanga, ndiyeno kusonkhanitsa ndi kuwotcherera zigawo zingapo za arc kukhala ma flanges athunthu;
3. Flanges zowotcherera matako zimakhala ndi miyezo yosiyanasiyana yopangira ntchito ndi kupanga, ndipo zimatha kupangidwa ndikugwiritsidwa ntchito molingana ndi miyezo yofananira, kuti azindikire kugwiritsa ntchito mtengo ndi ntchito ya ma flanges owoneka mwapadera pochita.
