Phambili Curved Motorized Impeller
Uma sesichaze izinga lokugeleza kwevolumu esilidingayo, noma ngabe lokhu ukunikeza umoya omusha noma ukupholisa inqubo, sidinga ukuhlanganisa lokhu nokumelana nokugeleza okuzotholwa ifeni esicelweni.Izinga lokugeleza kwevolumu, (ku-m3/hr) kanye nokucindezela (ku-Pascals - Pa), kuhlanganiswe ukuze kube indawo yomsebenzi okumele ifeni isebenze phezu kwayo.Kubalulekile ukuthi sikhethe ifeni isici sayo sokusebenza esihlangabezana nephuzu lomsebenzi elidingekayo endaweni noma eduze nendawo yokusebenza kahle okuphezulu.Ukusebenzisa ifeni ezingeni eliphezulu kakhulu kunciphisa ukusetshenziswa kwamandla nomsindo ophuma kufeni ngenkathi iletha ukusebenza okudingekayo.
Isebenza kanjani i-Forward Curved Centrifugal Fan?
Igama elithi, 'Ifeni Ye-Centrifugal' lisuselwa kuhlangothi lokugeleza kanye nendlela umoya ongena ngayo ku-impeller uye ohlangothini lwe-axial bese uphumela ngaphandle usuka esiyingini sangaphandle sefeni.Umehluko ekuqondeni kokugeleza phakathi kwefeni eyi-centrifugal eya phambili nangemuva isiqondiso lapho umoya uphuma khona kusiyingi se-impeller.Nge-impeller egobile emuva, umoya uphuma uye endaweni eyi-radial kuyilapho umoya ogobile oya phambili uphuma ngokuzenzakalelayo ukusuka kusiyingi sefeni.
Ifeni eyi-centrifugal egobile phambili ibonakala ngesimo sayo esiyisilinda kanye nezindwani eziningi ezincane kumjikelezo we-impeller.Esibonelweni esiboniswe ngezansi, ifeni izungeza ibheke njengewashi.
Ngokungafani ne-impeller egobile eya emuva, i-impeller eya phambili egobile idinga indawo yokuhlala eguqula umoya wesivinini esikhulu ishiya amathiphu e-impeller blade ibe amandla amile wejubane eliphansi.Ukuma kwezindlu kubuye kuqondise ukugeleza komoya endaweni yokuphuma.Lolu hlobo lwezindlu zabalandeli ngokuvamile lwaziwa ngokuthi umqulu;kodwa-ke, kungabuye kubizwe ngokuthi yi-volute noma i-sirocco housing.Ngokufaka i-impeller eya phambili egobile endlini yokuskrola, sivame ukubhekisela kuyo njengesivutheli esigobile phambili.
Kunezinhlobo ezimbili zama-blower asebenzisa i-impeller enenjini egobile eya phambili njengoba kukhonjisiwe ngezansi...
Isivuthelizi se-inlet esisodwa ngakwesobunxele, sidonsa umoya sisuka ohlangothini olulodwa lwendlu ngokungena endaweni eyindilinga bese siwuqondisa endaweni yokuphuma isikwele, (ebonakala lapha nge-flange ekhuphukayo).I-double inlet blower inomoya obanzi wokuskrola odonsa umoya ovela ezinhlangothini zombili zomqulu uwuletha endaweni ebanzi yesikwele.
Njengefeni eyi-centrifugal egobile emuva, uhlangothi lokumunca lwe-impeller blade ludonsa umoya phakathi nendawo yefeni okuholela ekushintsheni okuqondile kokugeleza komoya phakathi kwendawo yokungena nokukhipha okungu-90o.
Isici sabalandeli
Indawo yokusebenza engcono kakhulu yefeni eyi-centrifugal egobile phambili yilapho isebenza ngengcindezi ephezulu.Ifeni eyi-centrifugal eya phambili egobile isebenza kangcono uma kudingeka ukucindezela okuphezulu ngokumelene nokugeleza kwevolumu ephansi.Igrafu engezansi ikhombisa indawo yokusebenza enhle…
Ukugeleza kwevolumu kuhlelwa eduze kwe-X-axis futhi ukucindezela kwesistimu kuhlelwa ku-Y-eksisi.Uma ingekho ingcindezi ohlelweni, (isiphephetha-moya sivunguza ngokukhululeka), ifeni eyi-centrifugal egobile phambili izokhiqiza ukugeleza kwevolumu okukhulu kakhulu.Njengoba ukumelana nokugeleza kusetshenziswa ohlangothini lokumunca noma lokukhipha umoya wefeni, izinga lokugeleza kwevolumu lizokwehla.
Ukuqapha kufanele kusetshenziswe lapho kukhethwa isiphephetha-moya esigobile esiya phambili esizosebenza ngomfutho ophansi kanye nokugeleza kwevolumu ephezulu.Kuleli qophelo, i-impeller isebenza endaweni yokudayisa ye-aerodynamic ngendlela efanayo neyefeni ye-axial esebenza endaweni yesihlalo sejika layo.Kuleli qophelo umsindo nokusetshenziswa kwamandla kuzoba sezingeni eliphezulu ngenxa yesiyaluyalu.
Ukusebenza kahle okuphezulu kusezingeni elibizwa ngokuthi idolo lejika lesici.Kuleli qophelo isilinganiso samandla okukhiphayo wefeni (Ukugeleza kweVolumu (m3/s) x Ukuthuthukiswa kwe-Static Pressure (Pa) kanye nokokufaka kwamandla kagesi (W) kusezingeni eliphezulu kakhulu futhi umfutho womsindo okhiqizwa yisiphepho uzoba lapho kuthule kakhulu. Ngaphezulu nangaphansi kobubanzi obuphelele bokusebenza ukugeleza kuyo yonke ifeni kuba nomsindo futhi ukusebenza kahle kwesistimu yabalandeli kuyehla.
Inzuzo yokusebenzisa i-impeller eyodwa enenjini egobile yokungena ngaphambili ukuthi inesici sabalandeli esiwumqansa.Lokhu kuwusizo ikakhulukazi kumasistimu adinga amazinga angaguquki okuhlunga.Njengoba umoya udlula kusihlungi esiyizinhlayiyana isihlungi sibamba uthuli oluphuma emoyeni kanye nempova, lapho izinga lokuhlunga libe lincane kakhulu izinhlayiya eziboshwe yisihlungi.Ngokuhamba kwesikhathi isihlungi sizovaleka ngokwandayo ukungcola nemfucumfucu okunomthelela wokuthi kudingeka ingcindezi eyengeziwe ukuze kulethwe umthamo womoya ofanayo.Ukusebenzisa i-impeller enejika lesici esiwumqansa kulokhu kusho ukuthi njengoba isihlungi siya ngokuya sivaleka, ukugeleza kwevolumu kuhlala kungashintshi ngenkathi ukucindezela kusihlungi sikhula.
Inzuzo yokusebenzisa i-double inlet front curved impeller ukuthi kusukela ku-blower kasayizi omncane ingaletha ukugeleza kwevolumu ephezulu.Ukuvumelana ngokusebenzisa i-double inlet blower ukuthi inokuthuthukiswa kwengcindezi ephansi okusho ukuthi ingasebenza kuphela ngezinhlelo eziphansi zokucindezela.
Izinketho zokukhweza
Njengoba kushiwo ngaphambili, i-impeller enenjini egobile eya phambili ikhiqiza umoya wesivinini esikhulu ezihlokweni ze-blade edinga ukuqondiswa futhi yehliswe ukuze iguqule ingcindezi eguquguqukayo ibe yingcindezi emile.Ukwenza lokhu kube lula, sakha umqulu ozungeze i-impeller.Umumo udalwa isilinganiso samabanga ukusuka enkabeni ye-impeller kuya endaweni yokuphuma kwefeni.Njengefeni eligobile elibuyela emuva kuyanconywa ukuthi kube nokugqagqana okuncane phakathi kwendandatho yokungena kanye nomlomo we-impeller.Kokubili ukucatshangelwa okukhulayo kukhonjisiwe kumdwebo ongezansi...
I-diameter yeringi yokungena kufanele ivumele kuphela igebe elincane phakathi kwe-impeller neringi ukuze kugwenywe ukujikeleza kabusha komoya.
Izimpawu eziyinhloko - ukucindezelwa
Kubalulekile ukuqinisekisa imvume eyanele ekumunceni naseceleni kwefeni…
Ukungavuleki okwanele ohlangothini lokumunca lwefeni kuzonyusa isivinini sokungena okuzoholela esiphithiphithini.Lesi siphithiphithi sizokwandiswa njengoba umoya udlula ku-impeller okwenza ukudluliselwa kwamandla kusuka ku-fan blade kuya emoyeni kungasebenzi kahle, kubangele ukudala umsindo owengeziwe futhi kunciphise ukusebenza kahle kwabalandeli.
Izincomo ezijwayelekile zezimo zokungena nokukhipha amanzi yilezi:
I-Inlet Side
- Akukho ukuphazamiseka noma ukuguqulwa kwendlela yokugeleza phakathi kwebanga elingu-1/3 lobubanzi befeni ukusuka endaweni yokungena kwefeni
Isifinyezo - Kungani Khetha ifeni ye-centrifugal eya phambili egobile?
Lapho iphoyinti lomsebenzi elidingekayo liwela endaweni yokucindezela kwesistimu ephakeme ngokuhambisana nokugeleza kwevolumu ephansi kusici sefeni kufanele kucatshangelwe ifeni eyodwa ebheke phambili egobile eyi-centrifugal.Uma imfuneko yohlelo lokusebenza iwukugeleza kwevolumu ephezulu emvilophini yesikhala esikhawulelwe kufanele kucatshangelwe ifeni eyi-centrifugal eyi-inlet ephindwe kabili egobile.
I-fan kufanele ikhethwe ngaphakathi kobubanzi bayo obukhulu kulokho okwaziwa ngokuthi idolo lejika lesici.Iphuzu lokusebenza kahle kakhulu liseduze nomkhawulo wengcindezi ephezulu kwijika lesici sabalandeli lapho nalo lisebenza ngokuthula.Ukusebenza ngaphandle kobubanzi obukhulu (emazingeni adlulele okugeleza kwevolumu ephezulu) kufanele kugwenywe njengoba isiphithiphithi nokusebenza kahle kwe-aerodynamic kwe-impeller blade kulawa maphuzu kuzodala umsindo futhi isixhumi sizobe sisebenza endaweni yokudayisa ye-aerodynamic.Emazingeni okucindezela aphansi kanye nokugeleza kwevolumu ephezulu kufanele kucatshangelwe izinga lokushisa lokusebenza kwenjini elayishiwe njengoba kunethuba lokuthi kuvele ukushisa ngokweqile kwemoto.
Umoya ohlangothini lwe-inlet we-impeller kufanele ugcinwe ubushelelezi futhi u-laminar ngangokunokwenzeka.Ukwandisa ukusebenza kahle okungenani imvume ye-1/3rd ye-impeller diameter kufanele ivunyelwe endaweni yokufaka ifeni.Ukusebenzisa iringi yokungena (Inlet nozzle) edlula i-impeller inlet kuzosiza ukuqeda ukuphazamiseka kokugeleza ngaphambi kokuba umoya udonswe ngefeni, kunciphise umsindo obangelwa isiyaluyalu, kugcine ukusetshenziswa kwamandla endaweni yomsebenzi kube kuncane futhi kwandise ukusebenza kahle.
Isici sokusebenza esiwumqansa, amandla okucindezela okuphezulu kwama-inlet blower kanye namandla okugeleza okuphezulu kwama-inlet blower angena kabili kusho ukuthi ifeni egobile eya phambili iyindlela ewusizo yokucatshangelwa kulo lonke uhlobo olubanzi lokufakwa.
