Makhalidwe ndi mfundo yosindikiza ya flanges yowotcherera

Flange kuwotcherera flange amatanthauza flange yomwe imalumikizidwa ndi chidebe kapena payipi kudzera mu kuwotcherera kwa fillet. Ikhoza kukhala flange iliyonse. Kutengera kukhulupirika kwa mphete ya flange ndi gawo la chubu chowongoka pakupanga, yang'anani flange yonse kapena lotayirira padera. Pali mitundu iwiri ya mphete za flanges zowotcherera: khosi ndi khosi. Poyerekeza ndi khosi welded flanges, lathyathyathya welded flanges ndi dongosolo losavuta ndi zipangizo zochepa, koma kulimba kwawo ndi kusindikiza ntchito si bwino ngati khosi welded flanges. Flange welded flanges chimagwiritsidwa ntchito polumikiza sing'anga ndi otsika kuthamanga ziwiya ndi mapaipi.

Flat welded flanges sikuti amangopulumutsa malo ndi kulemera kwake, koma chofunika kwambiri, amaonetsetsa kuti zolumikizira sizikudumphira ndipo zimakhala ndi ntchito yabwino yosindikiza. Chifukwa cha kuchepa kwa m'mimba mwake kwa chinthu chosindikizira, kukula kwa compact flange kumachepetsedwa, zomwe zidzachepetsa gawo lapakati pa malo osindikizira. Kachiwiri, flange gasket yasinthidwa ndi mphete yosindikizira kuti atsimikizire kuti malo osindikizira akugwirizana ndi malo osindikizira. Mwanjira imeneyi, kupanikizika pang'ono kokha kumafunika kukakamiza mwamphamvu chivundikirocho. Pamene kuthamanga kofunikira kukucheperachepera, kukula ndi kuchuluka kwa mabawuti kumatha kuchepetsedwa. Chifukwa chake, mtundu watsopano wa flange wowotcherera wokhala ndi kukula kochepa komanso kulemera kwake (70% mpaka 80% yopepuka kuposa ma flange achikhalidwe) adapangidwa. Chifukwa chake, mtundu wa flange welded ndi mtundu wapamwamba kwambiri wa flange womwe umachepetsa mtundu ndi malo, ndipo umagwira ntchito yofunika kwambiri pamafakitale.

Mfundo yosindikiza ya flange yotchinga: Malo awiri osindikizira a bolt amapanikiza chosindikizira cha flange ndikupanga chisindikizo, koma izi zitha kuwononganso chisindikizo. Kuti musunge kusindikiza, ndikofunikira kukhalabe ndi mphamvu yayikulu ya bawuti. Chifukwa chake, ndikofunikira kukulitsa mabawulo. Bawuti yokulirapo iyenera kufanana ndi nati yayikulu, zomwe zikutanthauza kuti bawuti yokulirapo imafunikira kuti apange mikhalidwe yomangitsa mtedza. Komabe, kukula kwake kwa bolt, kupindika kwa flange komwe kumagwiritsidwa ntchito kudzachitika.

Njira iyi ndikuwonjezera makulidwe a khoma la gawo la flange. Chida chonsecho chidzafuna kukula kwakukulu ndi kulemera kwake, zomwe zimakhala nkhani yapadera m'madera akumidzi, chifukwa kulemera kwa flanges yophwanyika nthawi zonse kumakhala kodetsa nkhawa kwambiri komwe anthu ayenera kumvetsera.
