Iyini i-flange? Yiziphi izigaba? Ungaxhuma kanjani? Ake ngikuchazele

Uma kukhulunywa ngeFlange, abantu abaningi bazizwa bengajwayelekile. Kepha kulabo abenza ukufakwa kwemishini noma ubunjiniyela, kufanele bakujwayele 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 yokushisela i-flange, i-neck butt welding flange, i-neck flat welding flange, i-socket welding flange, indandatho yokushisela izinqe evulekile, indandatho yokushisela efulethini evulekile, isembozo se-flange, i-flange ikhava.

2.Ngokwemishini (JB) indinganiso yezimboni: i-flange ebalulekile, i-butt welding flange, i-flange ye-welding flat, i-butt welding ring plate flange evulekile, ipuleti eliyisicaba lendandatho yokushisela i-flange evulekile, i-flanging ipuleti eliyindandatho 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

I-1.Uxhumano lwe-flange kufanele lugcinwe 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 ngembobo eyisicaba, 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.
