Iindidi zeenkqubo zokuvelisa iiflange zensimbi ezingenasici
I-flange yensimbi engenasici yinxalenye ebalulekileyo yokudibanisa imibhobho kunye nezixhobo. Ineempawu zokumelana nobushushu obuphezulu, ukumelana nokugqwala kunye nokutywinwa kakuhle. Iinkqubo eziqhelekileyo zokuvelisa i-flange yensimbi engenasici zihlulwe kakhulu zibe ziindidi ezine: ukubumba, ukuphosa, ukusika, kunye nokuqengqeleka.
(1) Phosa iflenge yentsimbi engatyiwayo
Inkqubo yokutofa intsimbi etyhidiweyo kwisingundo ukuphosa iiflange zentsimbi engenasici ibizwa ngokuba yindlela yokugalela. Iinzuzo zezi: imilo echanekileyo kunye nobukhulu besithuba esingenanto, umthamo omncinci wokucubungula, ixabiso eliphantsi, kunye nokubumba kunokulungelelaniswa ngokweemfuno zabathengi ukuvelisa iimilo ezinzima ngakumbi. Ukungalungi: Iziphene zokuphosa (iipores, iintanda, ukubandakanywa), isakhiwo sangaphakathi esingenakulungelelaniswa sokuphosa, amandla okucheba angalunganga kunye namandla okuqina. Ewe kunjalo, kukwakho neenkqubo eziphezulu zentsimbi engenastainless flange ezinokunciphisa ezo ntsilelo. Ngokomzekelo, i-centrifugal i-stainless steel flanges luhlobo lwe-cast stainless steel flanges. Indlela ye-centrifugal yindlela echanekileyo yokuphosa yokuvelisa iiflange zensimbi ezingenasici. Iiflange zensimbi ezingenasici eziphonswe ngolu hlobo zihle kakhulu kunamalungiselelo okulahla isanti eqhelekileyo, umgangatho uphuculwe kakhulu, kwaye awuchanekanga kwiingxaki ezinjengeepores, iintanda kunye netrakoma.Oku kulandelayo yinkcazo ecacileyo yokuphosa i-centrifugal yeeflange zensimbi ezingenasici.
(2) I-Flange yensimbi engenasici
Iiflange zentsimbi egxunyekiweyo ezenziweyo zinomxholo wekhabhoni osezantsi kuneeflange zentsimbi engatyiwayo kwaye azifane zikwazi ukurusa. I-forgings ineendlela ezilungileyo kunye nesakhiwo esixineneyo. Iipropathi zabo zoomatshini zingcono kunezo zenziwe ngeeflange zentsimbi engatyiwayo kwaye ziyakwazi ukumelana namandla aphezulu okucheba kunye noxinzelelo. Ulwandiso.
Iiflange eziqhelekileyo ezenziwe ngentsimbi engenasici ziye zenziwe kwaye zenziwe.
I-Flange eyakhiweyo yi-flange eyenziwe ngokulungiswa okushushu kwezixhobo zetsimbi kwaye emva koko iyabetha. Eyona nto iphambili yale nkqubo kukusebenzisa ubushushu obuphezulu kunye noxinzelelo oluphezulu ukuguqula ngokuthe ngcembe izinto zetsimbi ukuze imilo kunye nokusebenza kwayo kuphuculwe.
Umahluko phakathi kweflange eyenziweyo kunye neflange eyenziweyo kukuba isebenzisa ukusebenza komatshini ukubumba izinto zetsimbi, inkqubo yokwenziwa kwesinyithi efana naleyo yeflange eyenziweyo. Le nkqubo inxulumene ne-forging deformation endaweni yokwenza ngesandla.
Oku kulandelayo yinkcazo ecacileyo yeeflange zentsimbi ezibunjiweyo kunye neeflange zentsimbi edibeneyo.
(3) Sika i-flange yensimbi engenasici
Sika ngokuthe ngqo idiskhi yeflange yangaphakathi nangaphandle kunye nobungqingqwa kwipleyiti yentsimbi engenastainless, uze ulungise imingxuma yebholiti kunye nemigca yamanzi. Ubungakanani beeflange zensimbi ezingenasici ezisikiwe kwaye ziveliswe ngokubanzi azidluli kwi-DN150. Ukuba ubungakanani budlula i-DN150, iindleko ziya kunyuka kakhulu.
(4) I-flange yentsimbi eqengqelekayo
Inkqubo yokusika iipleyiti zensimbi ezingenasici zibe yimicu kwaye emva koko ziqengqeleke kwizangqa zisetyenziswa kakhulu ekuveliseni ezinye iiflange ezinkulu zentsimbi. Emva kokuqengqeleka ngempumelelo, i-welded, emva koko ifakwe, kwaye emva koko i-waterline kunye nemingxuma ye-bolt icutshungulwa. Kuba imathiriyeli ekrwada iyipleyiti ephakathi, ukuxinana kulungile. Inkqubo ye-welding kwi-interface ye-flange egobileyo yinto ephambili ephambili, kwaye i-X-ray okanye ukuhlolwa kwefilimu ye-ultrasonic kuyadingeka.
