Uma kukhulunywa ngeFlange, abantu abaningi bazizwa bengajwayelekile.Kepha kulabo abenza ukufakwa kwemishini noma ubunjiniyela, kufanele bajwayele kakhulu.I-Flange ibizwa nangokuthi i-flange plate noma i-flange.Igama layo liwukuhunyushwa kwe-English flange yayo.Yingxenye exhuma i-shaft kanye ne-shaft.Isetshenziselwa ukuxhumana phakathi kwamapayipi, ukufakwa kwamapayipi noma okokusebenza, inqobo nje uma kusezindizeni ezimbili.Izingxenye zokuxhuma eziboshiwe futhi ezivaliwe endaweni ezungezile zingabizwa ngokuhlangene ngokuthi ama-flange.
Ukuhlukaniswa kwama-flanges
1.Ngokwezindinganiso zemboni yamakhemikhali: i-flange ebalulekile, i-flange enezintambo, i-flange ye-flange yokushisela, i-flange ye-neck butt welding, i-neck flat welding flange, i-socket welding flange, indandatho yokushisela izinqe evulekile, indandatho yokushisela efulethini evulekile, ikhava ye-flange yocingo, i-flange ikhava.
2.Ngokwemishini (JB) indinganiso yezimboni: i-flange ebalulekile, i-butt welding flange, ipuleti le-flange lokushisela, ipuleti lendandatho yokushisela izinqe elixegayo, ipuleti lendandatho yokushisela eliyisicaba elixegayo, ipuleti lendandatho elixegayo elixegayo, ikhava ye-flange, njll.
Nakuba kunezinhlobo eziningi zama-flange, uhlobo ngalunye lwe-flange luqukethe izingxenye ezintathu, okokuqala i-flange ngokwayo, ezobekwa phezu kwepayipi, bese kuba i-gasket elingana phakathi kwama-flange amabili, angahlinzeka ngokuqina nokusebenza kahle. uphawu.
Ngenxa yendima ebalulekile kanye nokusebenza okuphelele kwama-flanges empilweni, asetshenziswa kakhulu embonini yamakhemikhali, yomlilo, ye-petrochemical kanye ne-drainage.
Nakuba izingxenye ezincane ezifana nama-flange zingabonakali kuwo wonke umkhiqizo, indima yazo ibaluleke kakhulu.
Ukuxhumana kwe-Flange
1.Ukuxhumeka kwe-flange kufanele kugcinwe ku-axis efanayo, ukuphambuka okuphakathi kwembobo ye-bolt akufanele kudlule u-5% we-diameter yembobo, futhi i-bolt kufanele ifakwe ngokukhululekile.Ama-bolts axhumayo we-flange kufanele abe nezincazelo ezifanayo, isiqondiso sokufaka kufanele sifane, futhi ama-bolts kufanele aqiniswe ngokulinganayo nangokulinganayo.
2.Amawasha ama-diagonal anobukhulu obuhlukahlukene akufanele asetshenziselwe ukunxephezela ukungafani kwama-flange.Ungasebenzisi amawasha aphindwe kabili.Lapho i-gasket enkulu yobubanzi idinga ukuhlukaniswa, akufanele iboshwe nge-port flat, kodwa kufanele ibe ngesimo se-diagonal lap noma i-labyrinth.
3.Ukuze kube lula ukufakwa nokuhlakazeka kwe-flange, ama-bolts okuqinisa kanye ne-flange surface akufanele kube ngaphansi kuka-200 mm.
4.Uma uqinisa ama-bolts, kufanele kube yi-symmetrical kanye ne-intersecting ukuze kuqinisekiswe ukucindezeleka okufanayo ku-washer.
5.Ama-bolts namantongomane kufanele ahlanganiswe ne-molybdenum disulfide, amafutha e-graphite noma i-graphite powder ukuze kususwe okulandelayo: insimbi engagqwali, i-alloy steel bolts namantongomane;izinga lokushisa lomklamo wamapayipi ngaphansi kuka-100°C noma u-0°C;izinsiza zomoya ovulekile;ukugqwala komkhathi noma imidiya ebolayo .
6.Amawasha ensimbi afana nethusi, i-aluminium nensimbi emnene kufanele akhishwe ngaphambi kokufakwa.
7.Akuvunyelwe ukungcwaba ngokuqondile uxhumano lwe-flange.Ukuxhunywa kwamapayipi agqitshiwe kuzoba nemithombo yokuhlola.Uma kufanele ingcwatshwe, kufanele kuthathwe izinyathelo zokulwa nokugqwala.
