Ama-flanges anobubanzi obukhulu asetshenziswa kakhulu embonini yemishini

Abstract: Lesi sihloko sethula izimo ezisebenzayo kanye nezinqubo zokukhiqiza zama-flanges anobubanzi obukhulu

Ama-flanges anobubanzi obukhulu asetshenziswa kabanzi, futhi ububanzi bokusebenza bunqunywa izici zabo. Asetshenziswa kakhulu kumfutho ophansi (ukucindezela okulinganiselwe aweqi ku-2.5MPa) umoya ocindezelwe ongahlanjululwanga, amanzi azungezayo anomfutho ophansi nezinye izikhathi ezinezimo zemidiya ezixekethile, futhi zinenzuzo yokuba ishibhile uma kuqhathaniswa. Izinto zokwakha ziyi-carbon steel, insimbi engagqwali ne-alloy steel, njll.

Ama-flange avamile anobubanzi obukhulu ahlanganisa ama-flange welding ayisicaba kanye nama-butt welding flange, kanye nama-flange anentambo enobubanzi obukhulu ayivelakancane kakhulu. Ekukhiqizweni nasekuthengisweni kwangempela, imikhiqizo yokushisela eyisicaba isabala ingxenye enkulu. Ama-flange welding anobubanzi obukhulu nama-butt welding ama-flange anobubanzi obukhulu anezakhiwo ezihlukene kanye nobubanzi bokusebenzisa, futhi izici nezinzuzo ezingaboniswa nazo zizohluka. Ngakho-ke, lapho uzisebenzisa, kufanele zisetshenziselwe ububanzi obuhlukene ukuze kuqinisekiswe ukuthi i-flange idlala indima ebalulekile. Ama-flange we-welding flat anobubanzi obukhulu anokuqina okubuthakathaka futhi afanele izikhathi ezinengcindezi p≤4MPa; ama-flange wokushisela izinqe ezinobubanzi obukhulu abizwa nangokuthi ama-flanges anentamo enkulu enobubanzi obukhulu, anokuqina okukhulu futhi afanele izikhathi ezinengcindezi ephakeme kanye nezinga lokushisa.

Kunezinhlobo ezintathu zezindawo zokuvala i-flange ezinobubanzi obukhulu:

1. Indawo yokubeka uphawu eyisicaba, elungele izikhathi ezinomfutho ophansi kanye nemidiya engenabuthi;

2. Indawo evalekayo ne-convex, efanelekile ngezikhathi ezinomfutho ophakeme kancane;

3. Indawo yokuvala i-Tenon ne-groove, ilungele ukuvutha, ukuqhuma, imithombo yezindaba enobuthi kanye nezikhathi zokucindezela okukhulu. Ukufakwa kwamapayipi e-Flange ezakhiwo ezahlukene kunokusebenza okuhle komkhiqizo emikhakheni ehlukene, futhi imiphumela ekhiqizwayo izohluka kuye ngezikhathi nezikhala ezifanele.

Inqubo yokukhiqiza ama-flanges ensimbi engagqwali enobubanzi obukhulu ihlukaniswe yaba ukugoqa kanye nokwenza

Inqubo yokugoqa: Inqubo yokusika amapheshana ukusuka epuleti eliphakathi bese iwagoqa eyisiyingi ibizwa ngokuthi ukugoqa, okusetshenziselwa kakhulu ukukhiqizwa kwamanye amaflange ensimbi engagqwali. Ngemuva kokuthi ukugoqa kuphumelele, i-welding iyenziwa, bese i-flatning, bese izinqubo ze-waterline kanye ne-bolt hole zicutshungulwa.

Ama-flange angama-diameter amakhulu atholwe ngokuvamile anekhabhoni ephansi kunama-flange anobubanzi obukhulu, akulula ukugqwala, anezingqimba ezihleleke kangcono, aminyene kakhulu ngokwakheka, anezakhiwo ezingcono zokusebenzisa ama-flanges anobubanzi obukhulu, futhi angakwazi ukumelana nokusheka okuphezulu. kanye namandla aqinile

Inqubo yokubumba ngokuvamile iqukethe izinyathelo ezilandelayo, okuwukuthi, ukukhetha amabhilidi ensimbi ekhwalithi ephezulu ukuze avale, ashisise, akhe, futhi apholiswe ngemva kokufoja. Izindlela zenqubo yokubumba zihlanganisa ukufoja mahhala, ukufoja ifa kanye nokufoja ulwelwesi. Ngesikhathi sokukhiqiza, izindlela zokubumba ezihlukene zikhethwa ngokuya ngekhwalithi ye-forging kanye nenani lamaqoqo okukhiqiza.

Ukufoja kwamahhala kunokukhiqiza okuphansi kanye nesibonelelo esikhulu sokusebenza kwemishini, kodwa amathuluzi alula futhi ahlukahlukene, ngakho-ke asetshenziswa kabanzi ukwenza izingcezu ezilodwa kanye namaqoqo amancane ama-forging anomumo olula. Imishini yokufoja yamahhala ihlanganisa izando zomoya, izando zomoya we-steam kanye nomshini wokunyathelisa we-hydraulic, olungele ukukhiqizwa kwama-forging amancane, aphakathi nendawo namakhulu ngokulandelana.

Ukuqanjwa kwemodeli ukubeka i-billet eshisiwe endaweni yokufaka idiyizi engagxili emshinini wokubumba we-die forging. I-Die forging inokukhiqiza okuphezulu, ukusebenza okulula, futhi kulula ukuwenza ngomshini nokuzenzakalela. Ama-Die forging anobude obuphezulu bokunemba, imvume yomshini omncane, kanye nokusabalalisa kwesakhiwo sefayibha okunengqondo kakhudlwana, okungase kuthuthukise impilo yesevisi yezingxenye.
