Phambili egobileyo i-Motorized Impeller
Xa sichaze isantya sokuhamba kwevolumu esiyidingayo, nokuba oku kukubonelela ngomoya omtsha okanye inkqubo yokupholisa, kufuneka sidibanise oku kunye nokumelana nokuhamba okuya kuhlangana nomqhubi kwisicelo.Umthamo wokuhamba kwevolumu, (kwi-m3 / hr) kunye noxinzelelo (kwi-Pascals - Pa), idibaniswe ukuba ibe yindawo yomsebenzi apho umqhubi kufuneka asebenze.Kubalulekile ukuba sikhethe ifeni enophawu lokusebenza oludibana nomsebenzi ofunekayo kwindawo okanye kufutshane nencopho yokusebenza kakuhle.Ukusebenzisa ifeni kwincopho yayo yokuphumelela kunciphisa ukusetyenziswa kwamandla kunye nengxolo ephuma kwifeni ngelixa ihambisa ukusebenza okufunekayo.
Isebenza njani iFani ye-Forward Curved Centrifugal?
Igama, 'iFan ye-Centrifugal' lithatyathwe kwicala lokuhamba kunye nendlela umoya ongena ngayo kwisithinteli kwicala le-axial kwaye emva koko uqhubelelelwe ngaphandle ukusuka kwisangqa sangaphandle sefeni.Umahluko kwindlela yokuhamba phakathi kwefeni ye-centrifugal eya phambili nasemva egobileyo licala apho umoya uphuma khona kwi-impeller circumference.Nge-impeller egobileyo ngasemva, umoya uphuma kwicala le-radial ngelixa umoya ogobileyo ongaphambili uphuma ngokungxamisekileyo ukusuka kwisangqa sefeni.
Ifeni ye-centrifugal egobileyo ibonakaliswe ngobume bayo be-cylindrical kunye neencakuba ezininzi ezincinci kwisangqa se-impeller.Kumzekelo oboniswe ngezantsi, ifeni ijikeleza kwicala elingasekunene.
Ngokungafaniyo ne-impeller egobileyo ebuyela ngasemva, i-impeller eya phambili egobileyo ifuna indlu eguqula umoya wesantya esiphezulu ishiya iincam zencakuba ye-impeller ibe ngamandla asezantsi esantya esimileyo.Ubume bendlu bukwalathisa ukuhamba komoya kwindawo yokuphuma.Olu hlobo lwezindlu zabalandeli ngokuqhelekileyo lwaziwa ngokuba ngumsongo;nangona kunjalo, inokubhekiswa kuyo njenge-volute okanye indlu ye-sirocco.Ngokufakela i-impeller eya phambili egobileyo kwizindlu zokuskrola, sihlala sibhekisa kuyo njengevuthela eligobileyo elingaphambili.
Zimbini iintlobo zezivuthelo ezisebenzisa i-impeller enemoto egotywe ngaphambili njengoko kubonisiwe ngezantsi...
Isivutheli-ngaphakathi esisodwa ngasekhohlo, sitsala umoya ukusuka kwelinye icala lendlu ngokusebenzisa indawo yokungena engqukuva kwaye iqondise kwindawo yokuphuma yesikwere, (ibonwa apha ngeflange enyukayo).I-double inlet blower inendlu esongwayo ebanzi ezoba umoya ukusuka kumacala omabini omqulu uyisa kwindawo yokuphuma ebanzi yesikwere.
Njengakwifeni ye-centrifugal egobileyo ngasemva, icala lokufunxa leblade ye-impeller litsala umoya ukusuka kumbindi wefeni nto leyo ekhokelela kutshintsho olukhomba indlela yokuhamba komoya phakathi kwendawo yokungena kunye nokuphuma kwe-90o.
UmFani weFan
Eyona ndawo yokusebenza yefeni ye-centrifugal egobileyo kuxa isebenza kuxinzelelo oluphezulu.Ifeni ye-centrifugal egobileyo isebenza ngcono xa uxinzelelo oluphezulu ngokuchasene nokuhamba kwevolyum esezantsi kufuneka.Igrafu engezantsi ibonisa eyona ndawo ilungileyo yokusebenza...
Ukuhamba kwevolumu kucwangciswe kunye ne-X-axis kwaye uxinzelelo lwenkqubo lucwangciswe kwi-Y-axis.Xa kungekho xinzelelo kwisixokelelwano, (ifeni ivuthela ngokukhululekileyo), ifeni ye-centrifugal egobileyo eya phambili iya kuvelisa owona mthamo mkhulu wokuhamba kwevolyum.Njengoko ukuchasana nokuhamba kusetyenziswe kwicala lokufunxa okanye ukukhupha i-fan, izinga lokuhamba kwevolumu liya kuhla.
Kufuneka kulumke xa kukhethwa ivuthela eligobileyo eliya phambili ukuze lisebenze kuxinzelelo oluphantsi kunye nokuhamba kwevolyum ephezulu.Ngeli xesha, i-impeller isebenza kwi-aerodynamic stall ngendlela efanayo ne-axial fan esebenza kwindawo ye-saddle ye-curve yayo.Ngeli xesha ingxolo kunye nokusetyenziswa kwamandla kuya kuba kwincopho yayo ngenxa yesiphithiphithi.
Ukuphumelela okuphezulu kwinqanaba elibizwa ngokuba yidolo le-curve yeempawu.Kweli nqanaba umlinganiselo wamandla aphumayo efeni (Umqukuqelo weVolume (m3/s) x Uphuhliso loxinzelelo oluzinzileyo (Pa) kunye negalelo lamandla ombane (W) likhulu kwaye uxinzelelo lwesandi oluveliswa yifeni luya kuba Ngaphezulu nangaphantsi kolona luhlu lulolona lusebenzayo ukuqukuqela kwifeni kuya kuba nomsindo ngakumbi kwaye ukusebenza kakuhle kwenkqubo yeefeni kuyancipha.
Uncedo lokusebenzisa i-impeller enenjini enye egobileyo kukuba inomnqantsa wefeni.Oku kuluncedo ngakumbi kwiinkqubo ezifuna amanqanaba angaguqukiyo okucoca.Njengoko umoya udlula kwisihluzo se-particulate isihluzi sibamba uthuli olusemoyeni kunye ne-pollen, okukhona umgangatho wokucoca ucoleka kokukhona usiba mancinci amasuntswana abanjwe sisihluzo.Ngokuhamba kwexesha isihluzo siya kugqunywa ngakumbi bubumdaka kunye nobutyobo obunesiphumo sokuba uxinzelelo olungakumbi luyafuneka ukuze kuhanjiswe umthamo womoya ofanayo.Ukusebenzisa i-impeller enegophe elimnqantsa kule meko kuthetha ukuba njengoko isihluzo siya sivaleka ngakumbi, ukuhamba kwevolyum kuhlala kungaguquguquki ngelixa uxinzelelo olungaphaya kwesihluzo lukhula.
Inzuzo yokusebenzisa i-double inlet ngaphambili egobileyo i-impeller kukuba ukusuka kwi-blower encinci yesayizi encinci inokuhambisa ukuhamba kwevolumu ephezulu.I-compromise ngokusebenzisa i-double inlet blower kukuba inophuhliso oluphantsi loxinzelelo oluthetha ukuba lunokusebenza kuphela ngeenkqubo eziphantsi zoxinzelelo.
Iinketho zokunyuka
Njengoko bekutshiwo ngaphambili, i-impeller ehamba phambili egobileyo ivelisa umoya wesantya esiphezulu kwiingcebiso zeblade ekufuneka iqondiswe kwaye icothiswe ukuguqula uxinzelelo oluguquguqukayo lube luxinzelelo olumileyo.Ukuququzelela oku, sakha umqulu ojikeleze i-impeller.Ubume benziwa ngumlinganiselo wemigama ukusuka kumbindi we-impeller ukuya kwi-fan outlet.Njengakwifeni egobileyo ngasemva kuyacetyiswa ukuba kubekho ukudibana okuncinci phakathi kweringi yokungena kunye nomlomo we-impeller.Zombini iingqwalaselo ezixhomileyo zibonisiwe kulo mzobo ungezantsi...
Idayamitha yeringi yokungena kufuneka ivumele kuphela isithuba esincinci phakathi kwe-impeller kunye neringi ukunqanda ukujikeleziswa komoya kwakhona.
Ukunyuka kweingqwalaselo - Ukucoca
Kubalulekile ukuqinisekisa ukucoceka okwaneleyo kwi-suction kunye necala le-fan ...
Ukungacoci ngokwaneleyo kwicala lokufunxa kwefeni kuya kwandisa isantya sokungena okuya kukhokelela kwisiphithiphithi.Esi siphithiphithi siya kwandiswa njengoko umoya udlula kwi-impeller eyenza ukuhanjiswa kwamandla ukusuka kwi-fan blade ukuya emoyeni ingasebenzi kakuhle, kubangele ukudala ingxolo eninzi kunye nokunciphisa ukusebenza kakuhle kwefeni.
Iingcebiso ngokubanzi malunga neemeko zokungena kunye nokukhupha:
Icala lokungena
- Akukho sithintelo okanye utshintsho kwindlela yokuhamba ngaphakathi kwe-1/3rd umgama wefan ngokwedayamitha ukusuka kwindawo yokungena yefeni
Isishwankathelo-Kutheni ukhetha ifeni ye-centrifugal egobileyo?
Xa indawo yoxanduva efunekayo iwa kwindawo yoxinzelelo lwenkqubo ephezulu ngokuchasene nokuhamba kwevolyum esezantsi kuphawu lwefeni isiziba esinye esibheke phambili esigobileyo se-centrifugal fan kufuneka siqwalaselwe.Ukuba imfuno yesicelo yeyokuqukuqela kwevolyum ephezulu kwimvulophu yendawo ethintelweyo i-double inlet ngaphambili egobile ifeni ye-centrifugal kufuneka ithathelwe ingqalelo.
Ifeni kufuneka ikhethwe phakathi kolona luhlu lwayo luphezulu into eyaziwa ngokuba lidolo legophe leempawu zayo.Incopho yencopho yokuphumelela kukusondele kumda woxinzelelo oluphezulu kwigophe leempawu zefeni apho ikwasebenza kweyona ndawo ithuleyo.Ukusebenza ngaphandle koluhlu oluphezulu (kwizinga eliphezulu lokuhamba komthamo ophezulu) kufuneka kugwenywe njengoko isiphithiphithi kunye nokusebenza kakuhle kwe-aerodynamic ye-impeller blade kula manqaku kuya kudala ingxolo kwaye i-impeller iya kusebenza kwi-aerodynamic stall.Kuxinzelelo oluphantsi kunye nomthamo ophezulu wokuhamba kufuneka kuqwalaselwe ubushushu bokusebenza kwemoto ephantsi komthwalo njengoko kunokwenzeka ukuba kubekho ubushushu obungaphezulu kwemoto.
Umoya kwicala lokungena le-impeller kufuneka ugcinwe ucolile kunye ne-laminar ngokusemandleni.Ukwandisa ukusebenza kakuhle ubuncinane ubuncinane be-1/3 ye-diameter ye-impeller kufuneka ivunyelwe kwi-fan inlet.Ukusebenzisa iringi yokungena (Inlet nozzle) egqithe kwi-impeller inlet kuya kunceda ukuphelisa ukuphazamiseka kokuhamba phambi kokuba umoya utsalwe ngefeni, ukunciphisa ingxolo ebangelwa sisiphithiphithi, gcina ukusetyenziswa kwamandla kwindawo yomsebenzi ukuya kubuncinci kunye nokwandisa ukusebenza kakuhle.
Uphawu lokusebenza olungumnqantsa, amandla oxinzelelo oluphezulu lwezivutheli zokungena ngaphakathi okukodwa kunye nokuhamba okuphezulu kwamandla okuvuthela okungaphakathi okuphindiweyo kuthetha ukuba ifeni egobileyo eya phambili lukhetho oluluncedo lokuqwalaselwa kuluhlu olubanzi lofakelo.
