Isingeniso:
AmaFlange, nakuba evame ukunganakwa, adlala indima ebalulekile ezimbonini ezihlukahlukene ezihlanganisa ezokukhiqiza, ezokwakha nezobunjiniyela.Lezi zingxenye ezibalulekile zisetshenziselwa ukuxhuma nokuvikela izingxenye ezihlukene ndawonye, ezihlinzeka ngokusimama nokuqinisekisa ukusebenza kahle kwezinhlelo.Kodwa liyini ngempela i-flange?Kulo mhlahlandlela obanzi, sizohlola izici zezinhlobo ezahlukene zama-flange futhi sihlole imisebenzi yawo, izinhlelo zokusebenza, kanye nokubaluleka kwezimbobo zawo zokufakwa.
Ukuqonda amaFlanges:
Ama-flange, asuselwa egameni elithi 'flange', abhekisela ezingxenyeni ezinomphetho ophakanyisiwe noma udebe ukuze uthole amandla engeziwe, ukuqina, nokunamathisela kalula.Ziza ngobujamo nobukhulu obuhlukene, kuya ngenhloso yazo kanye nezinto ezenziwe ngazo.Nakuba amanye ama-flange eyizingxenye ezizimele zodwa, ezinye ziyizinhlobo ezihlanganisiwe, njengamapayipi anama-flange komunye noma kokubili.Lezi zingxenye eziguquguqukayo zingatholakala kuhlelo olubanzi lwezinhlelo zokusebenza, njengamapayipi, amaphampu, ama-valve, nama-turbines.
Izici zezinhlobo ezahlukene zama-Flanges:
1. Ama-Weld Neck Flanges:
Ama-weld neck flange aziwa ngamahabhu awo amade, acijile ahlangana kancane nepayipi.Lawa ma-flange ahlinzeka ngokusebenza kahle kokugeleza koketshezi kanye nokusabalalisa kokucindezeleka, okuwenza afanelekele izinhlelo zokusebenza ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu.Intamo yokushisela inikeza amandla angeziwe nokusekelwa, iqinisekisa ukuxhumana okuphephile nokungavuziyo.Esetshenziswa kakhulu embonini ye-petrochemical ne-oyela, ama-weld neck flanges adumile ngenxa yokusebenza kwawo okuphezulu nokuqina.
2. Ama-Slip-On Flanges:
Ama-slip-on flange awuhlobo oluvame kakhulu lwama-flange, aziwa ngokufakwa kwawo kalula kanye nemvelo eyongayo.Lawa ma-flange ashibilika phezu kwepayipi bese eshiselwa nhlangothi zombili ukuze aqinise endaweni yawo.Ama-slip-on flange anikeza ukuguquguquka nokulula kokuqondanisa, okuwenza afanelekele izinhlelo zokusebenza ezinomfutho ophansi.Avame ukusetshenziswa ezimbonini ezifana nokuhlinzeka ngamanzi, amapayipi, kanye nezinhlelo zokuchelela.
3. Ama-Blind Flanges:
Ama-blind flange, njengoba negama lisho, asetshenziselwa ukuvala ukuphela kwepayipi lapho lingasetshenziswa.Lawa ma-flange aqinile awanazo izimbobo, ahlinzeka ngokuhlukaniswa okuphelele futhi avimbele ukuhamba kwezinto.Ama-blind flange abalulekile lapho amapayipi edinga ukuvalwa okwesikhashana noma lapho kudingeka khona ukufinyelela okulula ukuze kulungiswe.Ukwengeza, ama-flange ayimpumputhe angaba nobuso obuphakanyisiwe noma ubuso obuyisicaba, kuye ngezidingo zabo ezithile.
4. Ama-Socket Weld Flanges:
Ama-socket weld flange afana nama-slip-on flanges kodwa anesokhethi noma abhoboze ohlangothini lwangaphakathi ukuze avumele ukufakwa kwepayipi.Lawa ma-flange asetshenziselwa ikakhulukazi amasayizi amapayipi amancane kanye nezinhlelo zokucindezela okuphezulu.Ngokushisela ipayipi esokhethi, ama-socket weld flanges anikeza ukubekwa uphawu okuthembekile nokusebenza kahle kokugeleza.Zivame ukusetshenziswa ezimbonini zokucubungula amakhemikhali, izimboni ze-petrochemical, nezinye izinhlelo zokusebenza lapho ukuvimbela ukuvuza kubalulekile.
Ukubaluleka kwe-Flange Through-Holes:
Ama-flange afaka phakathi kwezimbobo zokufaka izikulufu, amabhawodi, noma izikhonkwane ukuze azinamathisele ngokuphephile kwezinye izingxenye.Lezi zimbobo zokubhoboza zidlala indima ebalulekile ekugcineni uzinzo nobuqotho bohlelo.Ngokuqondisa kahle nokubopha ama-flanges, ingozi yokuvuza, ukuphuka, kanye nokwehluleka kwesistimu kuncishiswa kakhulu.Ukwengeza, izimbobo zivumela ukuqaqa kalula ukulungiswa, ukuhlanza, noma ukushintshwa kwezingxenye, okuthuthukisa ukusebenza kahle nokuphila isikhathi eside kohlelo.
Isiphetho:
Ukuqonda izici nezinhlobo zama-flange kubalulekile ukuze kuqinisekiswe ukusebenza kahle kwezinhlelo ezimbonini ezihlukahlukene.Noma ngabe ama-weld neck flange ezinhlelo zokusebenza ezinomfutho ophezulu, ama-slip-on flanges ukuze kube nezindleko ezikahle, noma ama-blind flanges okuvalwa kwesikhashana, uhlobo ngalunye lwenza izinjongo ezihlukile.Izimbobo ezisemaceleni zivumela ukunamathiselwa okuvikelekile nokugcinwa kalula, okwenza uhlelo oluthembekile nolusebenza kahle.Njengoba ujula emhlabeni wama-flanges, uzothuthukisa ukwazisa okukhulu ngalezi zingxenye ezivame ukunganakwa kanye nomthelela wazo ekusebenzeni okungenazihibe kwezinqubo eziningi zezimboni.
