Ifeni luhlobo lomatshini osetyenziselwa ukucinezela kunye nokuthutha igesi. Ukusuka kwindawo yokujonga ukuguqulwa kwamandla, luhlobo lomatshini oluguqula amandla omatshini we-prime mover ibe ngamandla egesi.
Ngokomgaqo wokuhlelwa kwentshukumo, abalandeli banokwahlulwa babe:
· I-Turbofan – ifeni ecinezela umoya ngeencakuba ezijikelezayo.
· Ifeni yokufuduka entle – umatshini ocinezelayo nothutha irhasi ngokutshintsha umthamo werhasi.
Ihlelwa ngokwendlela yokuhamba komoya:
· Ifeni ye-Centrifugal – Emva kokuba umoya ungene kwi-impeller ye-fan axially, ixinzelelwe phantsi kwesenzo samandla e-centrifugal kwaye ihamba ngokuyintloko kwicala le-radial.
· I-Axial-flow fan – Umoya uqukuqela nge-axially kwipaseji yeblade ejikelezayo. Ngenxa yokusebenzisana phakathi kwe-blade kunye negesi, igesi ixinzelelwe kwaye ihamba malunga ne-axial direction kwi-cylindrical surface.
· i-mix-flow fan – Irhasi ingena kwincakuba ejikelezayo kwi-Engile ukuya kwishafti engundoqo ize impompoze malunga nekhowuni.
· I-Cross-flow fan - igesi idlula kwi-blade ejikelezayo kwaye iqhutywe yi-blade ukunyusa uxinzelelo.
Ukuhlelwa ngoxinzelelo lwemveliso ephezulu okanye ephantsi (ebalwe ngoxinzelelo olupheleleyo):
I-Ventilator - uxinzelelo lokukhupha ngaphantsi kwe-112700Pa;
· i-blower-exhaust pressure ranges ukusuka kwi-112700Pa ukuya kwi-343000Pa;
· icompressor – exhaust pressure ngaphezu kwe343000Pa;
Ukuhlelwa okuhambelanayo koxinzelelo oluphezulu noluphantsi lwefeni lungolu lulandelayo (kwimeko eqhelekileyo) :
· Uxinzelelo oluphantsi lwefeni ye-centrifugal: uxinzelelo olupheleleyo P≤1000Pa
· Uxinzelelo oluphakathi fan centrifugal: uxinzelelo olupheleleyo P=1000 ~ 5000Pa
· Uxinzelelo oluphezulu lwefeni ye-centrifugal: uxinzelelo olupheleleyo P=5000 ~ 30000Pa
· Uxinzelelo oluphantsi lwe-axial flow fan: uxinzelelo olupheleleyo P≤500Pa
· Uxinzelelo oluphezulu lwe-axial flow fan: uxinzelelo olupheleleyo P=500 ~ 5000Pa
Indlela ye-centrifugal yokubiza amagama abalandeli:
Umzekelo: 4-79NO5
Indlela yemodeli kunye nesitayilele:
Umzekelo: YF4-73NO9C
Uxinzelelo lwefeni ye-centrifugal lubhekiselele kuxinzelelo lokunyusa (ngokunxulumene noxinzelelo lwe-atmosphere), oko kukuthi, ukunyuka koxinzelelo lwegesi kwi-fan okanye umahluko phakathi koxinzelelo lwegesi kwindawo yokungena kunye nokuphuma kwefeni. . Inoxinzelelo lwe-static, uxinzelelo oluguquguqukayo kunye noxinzelelo olupheleleyo. Ipharamitha yokusebenza ibhekisela kuxinzelelo olupheleleyo (olulingana nokwahlukana phakathi koxinzelelo olupheleleyo lwe-fan outlet kunye noxinzelelo olupheleleyo lwe-fan inlet), kwaye iyunithi yayo isetyenziswa ngokuqhelekileyo iPa, KPa, mH2O, mmH2O, njl.
Ukuhamba:
Umthamo wegesi ohamba ngefeni ngexesha leyunithi, eyaziwa ngokuba ngumthamo womoya. Eqhele ukusetyenziswa Q ukumela, iyunithi eqhelekileyo; m3/s, m3/min, m3/h (imizuzwana, imizuzu, iiyure). (Ngamanye amaxesha kukwasetyenziswa “ukuhamba kobunzima” oko kukuthi, ubunzima berhasi equkuqela kwifeni ngexesha leyunithi, ngeli xesha kufuneka kuqwalaselwe ingxinano yerhasi yendawo yokungena, kunye nokwakheka kwerhasi, uxinzelelo lomoya wendawo, ubushushu berhasi, uxinzelelo lokungena. inempembelelo esondeleyo, kufuneka iguqulwe ukuze ifumane "ukuhamba kwerhasi" yesiko.
Isantya sokujikeleza:
Isantya sokujikeleza kweFan. Idla ngokuchazwa ngo-n, kwaye iyunithi yayo ngu-r/min (r ibonisa isantya, i-min ibonisa umzuzu).
Amandla:
Amandla afunekayo ukuqhuba ifeni. Ihlala ichazwa njenge-N, kwaye iyunithi yayo yi-Kw.
