Iinkqubo zokuphatha izinto eziphathekayo zifuna izisombululo zokuhamba komoya ezenza ngaphezu kokuhamba komoya-kufuneka zilawule izinto eziqinileyo ezininzi, zilawule uthuli, zithintele ukuvala, kwaye zigcine isantya esingaguqukiyo kwiindlela ezingalinganiyo okanye ezineengile. Xa iifeni ezisemgangathweni ze-centrifugal zisokola kwii-chutes ezithambekileyo, abaqhubi bajongana nokuchitheka, ukubuyisela umva imathiriyeli, kunye nokuhanjiswa okungafanelekanga. Kulapho ke Ithambekele seChute centrini fan inika ukusebenza okunokulinganiswa-kungekhona njengokwahluka kwe-niche, kodwa njengempendulo yobunjineli kwingxaki yefiziksi yehlabathi lokwenyani.
Sifake ngaphezu kwe-120 yabalandeli be-chute abathambekele ekuthandeni kwimigca yesamente ye-preheater, iinkqubo zebhoyila ezibaselwe ngamalahle, kunye neendawo zokulungisa izimbiwa eShandong naseShanxi. Kuzo zonke iimeko, indawo yokungaphumeleli yayingengomandla fan-yayiyindlela yokuhamba komoya. Izivutheli zeradial eziqhelekileyo zikhupha ngokuthe ngqo ukujikeleza. Kwi-chute ye-25°–45°, loo nto idala isiphithiphithi sezowuni zokwahlula ngasemva kwamaqhuma ezinto. Isicombululo? I-impeller yendlu ehlaziyiweyo, i-angle ye-inlet ephuculweyo, kunye ne-casing geometry eyomeleziweyo-eyenzelwe ukuba "ingaqhelani" nokuthambekela, kodwa ukuyixhaphaza.
Izigqibo ezithathu zobuchwephesha zahlula abalandeli be-chute centrifugal abakumgangatho ophezulu kwiiyunithi eziphindiweyo zenjongo jikelele:
- Ukukhupha ulungelelwaniso lwe-axis: I-flange yokuphuma ijikeleza i-15 ° -30 ° ngokunxulumene ne-motor shaft, ihambelana nee-angles ze-chute eziqhelekileyo ngaphandle kwee-elbows ze-duct okanye ukuhamba-distoring transit.
- I-impeller blade twist profile: Iiblade ezigobileyo eziya phambili kunye nokuhanjiswa kwe-asymmetric pitch zigcina uxinzelelo lwe-static ngaphezu kwe-3,200 Pa-nakwi-45% yokunciphisa ukuhamba kwe-volumetric okubangelwa yilahleko ye-chute friction
- Isiseko sokunyuka kokuqina: Iinyawo ezidityanisiweyo zolwakhiwo zifunxa ukungcangcazela kumaza axhaphakileyo kwi-vibrating feeder (12–18 Hz), ukuthintela ukunxitywa kwebheringi okubangelwa yiresonance.
Abanye banokuxoxa ukuba i-axial fan edibeneyo ifezekisa iziphumo ezifanayo ngexabiso eliphantsi. Kodwa idatha yasendle ibalisa elinye ibali: iiyunithi ze-axial zilahlekelwa yi-68% yoxinzelelo olusisigxina xa uphethe izohlwayo ze-limestone eziyingozi kwi-42 ° incline, ngelixa abalandeli bethu be-chute centrifugal be-inclined bagcina i-91% yoxinzelelo olulinganisiweyo kwi-angle efanayo kunye nokulayisha. Ngoba? Uyilo lwe-Axial luthembele ekuhambeni kwe-laminar-akunakwenzeka kwii-chutes ezirhabaxa, ezingaqhelekanga. Amandla e-Centrifugal, nangona kunjalo, asebenza ngokwe-orthogonally ukuya kumxhuzulane. Ityhala amasuntswana *kumphezulu we-chute, inyusa ukukhuhlana okusebenzayo kunye nokunciphisa umva wesilayidi. Sikuqinisekisile oku ngexesha lovavanyo oluqhubekayo lweeyure ezingama-72 kwiplanti yezitena ezichasayo: isantya sezinto eziphathekayo sihleli ngaphakathi kwe-± 3% yethagethi kwiinguqu ezintathu zeshifti, akukho luhlengahlengiso lwezandla olufunekayo.
Ifakwe kwiChute Centrifugal Fan
Ukwenza ngokwezifiso akukhethi-kwakhiwe kwinkqubo yokucacisa. Wonke umlandeli we-chute centrifugal esiwakhayo uqala ngomlinganiselo wethambeka le-chute, uhlalutyo lobungakanani besuntswana losasazo (nge-laser diffraction), kunye nobushushu obukhoyo/ukufuma okugawulwa ngaphezulu kweeyure ezingama-48. Kuphela kulapho sikhetha ibakala lemathiriyeli ye-impeller: i-Q345B yentsimbi yosetyenziso-msebenzi jikelele, i-1Cr18Ni9Ti engenastainless yokuphatha amalahle amanzi, okanye i-titanium alloy TC4 yendawo yegesi ye-sulphur-laden flue. Ukhetho lweemoto lulandela imephu yomjikelo ongqongqo womsebenzi-ubuchule be-IE3 busemgangathweni, kodwa sicacisa i-IE4 ene-variable-frequency drives xa ujingi lomthwalo ludlula i-40% phakathi kwencopho kunye nokungenzi nto. Izibiyeli zokunyuka ziquka izibonelelo zokwandisa i-thermal ukuya kwi-12 mm-ibaluleke kakhulu xa ufaka i-ducts yokukhupha i-kiln esebenza kwi-280 ° C.
IZibo Hongcheng Fan Co., Ltd. yenza ezi yunithi ngaphakathi endlwini kwiziko layo elingama-9,000 m² eZibo Blower Industrial Park. Akukho subassembly outsourcing. Yonke into eyenziwayo ifumana ulungelelwaniso oluguquguqukayo ukuya kwi-G2.5 ISO 1940-1 yonyamezelo-ingqinwe nge-laser vibrometers elungisiweyo, hayi nje ibhalansi yomgangatho wevenkile. Uvavanyo lokugqibela lubandakanya imizuzu ye-120 yokusebenza komthwalo ogcweleyo kwi-110% yesantya esilinganiselweyo, kunye nexesha langempela lokubeka iliso lokunyuka kweqondo lokushisa (max ΔT = 28 ° C), i-casing deflection (<0.12 mm), kunye namanqanaba e-acoustic emission (<82 dB (A)). Zonke iingxelo zovavanyo zithunyelwa kunye neyunithi. Uya kufumana amaxwebhu agcweleyo obuchwephesha-kubandakanya imizobo enobukhulu, i-torque specs, kunye noluhlu lokuqalisa-ku. hongchengfan.com.Inclined Chute Centrifugal Fan
I Ithambekele seChute centrini fan isombulula ingxaki elula ekhohlisayo: ukuhambisa izinto phezulu ngaphandle kokulahlekelwa kulawulo. Ayithathi indawo yabahambisi okanye i-vibratory feeders. Ibenza basebenze ngokuthembekileyo. Kwimisebenzi yezimayini apho ukumiswa kwe-chute okungacwangciswanga kubiza i-$ 18,000 / iyure ngexesha lokuphumla, okanye kwizityalo zemichiza apho ukuqokelela uthuli kubangela ukuphulwa kwe-ATEX, oku akukho malunga nokuhamba komoya-kumalunga nokuqhubeka nokusebenza. Njengoko iinkqubo zemizi-mveliso zikhula ngokudityaniswa ngakumbi kwaye zingaxoleli kangako, indima yabalandeli iyatshintsha ukusuka kwicandelo elincedisayo ukuya kwisixhobo sokwenza inkqubo. Yiyo loo nto senza injineli nganye kwichute yayo ethile-hayi kwiphepha lekhathalogu.
