Amasistimu okuphatha okubalulekile adinga izixazululo zokugeleza komoya ezenza okungaphezu nje kokuhambisa umoya—kumele alawule izinto eziqinile eziyinqwaba, alawule uthuli, avimbele ukuvala, futhi alondoloze isivinini esingaguquki ezindleleni ezingalingani noma ezine-engeli. Lapho abalandeli be-centrifugal abajwayelekile bezabalaza kuma-chute atshekile, opharetha babhekana nokuchitheka, ukubuyisela emuva impahla, kanye nokudlulisa okungasebenzi kahle. Yilapho ke Ethambekele emgqonyeni we-chute centrifugal fan iletha ukusebenza okulinganisekayo—hhayi njengokuhlukile kwe-niche, kodwa njengempendulo enobunjiniyela enkingeni ye-physics yomhlaba wangempela.
Sifake abalandeli be-chute abathambekele abangaphezu kuka-120 emigqeni yokushisisa kusengaphambili kukasimende, amasistimu okuphakela kukabhayela abaswa ngamalahle, nezindawo zokucubungula amaminerali eShandong naseShanxi. Kuzo zonke izimo, iphuzu lokuhluleka kwakungewona amandla abalandeli-bekuwukuqondisa kokugeleza komoya. Ama-radial blower ajwayelekile akhipha i-perpendicular to rotation. Ku-chute engu-25°–45°, lokho kudala izindawo ezihlukene zokuhlukanisa ngemuva kwezigaxa zezinto. Isixazululo? I-impeller housing ehlelwe kabusha, i-inlet vane angle ethuthukisiwe, kanye ne-casing geometry eqinisiwe—eklanyelwe ukuthi “ingavumelanise” nokuthambekela, kodwa ukuze iyisebenzise.
Izinqumo ezintathu zobuchwepheshe zihlukanisa abalandeli be-chute centrifugal abenza kahle kakhulu kumayunithi enhloso evamile:
- Khipha ukuqondanisa kwe-eksisi: I-outlet flange izungeza ngo-15°–30° ngokuhlobene ne-motor shaft, ifanise ama-engeli avamile we-chute ngaphandle kwama-elbows noma ukushintsha kokugeleza okuhlanekezela.
- Iphrofayili ye-impeller blade twist: Izindwani ezigobile phambili ezinokusabalalisa kwe-asymmetric pitch zisekela ukucindezela okumile ngaphezu kuka-3,200 Pa—ngisho naku-45% okuncishisiwe ukugeleza kwevolumu okubangelwa ukulahleka kwe-chute friction
- Ukuqina kokuqina kwesisekelo: Izinyawo ezihlanganisiwe zesakhiwo zimunca ukudlidliza kumaza okuvamile ekuphakeleni okudlidlizayo (12–18 Hz), ukuvimbela ukuguga kwe-resonance-induced bear
Abanye bangase baphikise ngokuthi i-axial fan edonsiwe ithola imiphumela efanayo ngezindleko eziphansi. Kodwa idatha yasenkambu ixoxa enye indaba: amayunithi e-axial alahlekelwa u-68% wengcindezi emile lapho ephatha izinhlawulo ze-limestone ezilimazayo ekukhuphukeni okungu-42°, kuyilapho abalandeli bethu be-chute centrifugal abathambekele begcina u-91% wengcindezi elinganiselwe nge-engeli efanayo nokulayisha. Kungani? Imiklamo ye-axial incike ekugelezeni kwe-laminar-akunakwenzeka kuma-chute amabi, angajwayelekile. Amandla e-Centrifugal, nokho, asebenza ngokwe-orthogonally kuya kumandla adonsela phansi. Iphusha izinhlayiya *ku-* endaweni ye-chute, ikhulise ukungqubuzana okusebenzayo futhi inciphise i-slide-back. Siqinisekise lokhu ngesikhathi sokuhlola okuqhubekayo kwamahora angu-72 endaweni yezitini eziphikisayo: isivinini sezinto ezibonakalayo sihleli phakathi kuka-±3% wethagethi kuzo zonke izinguquko ezintathu zamashifu, akukho ukulungisa okudingekile.
Umlandeli we-Chute Centrifugal ohlanganisiwe
Ukwenza ngendlela oyifisayo akuyona inketho—kwakhelwe kunqubo yokucaciswa. Wonke umlandeli we-chute centrifugal esiwakhayo uqala ngokulinganisa ukuthambeka kwe-chute, ukuhlaziya usayizi wezinhlayiyana zokusabalalisa (nge-laser diffraction), kanye nokungena kwezinga lokushisa/umswakama ngaphezu kwamahora angu-48. Kulapho kuphela lapho sikhetha khona izinga lempahla ye-impeller: Insimbi ye-Q345B yezinhlelo zokusebenza ezivamile, i-1Cr18Ni9Ti engenasici yokuphatha amalahle emanzi, noma i-titanium alloy TC4 yezindawo zegesi ye-sulfur-laden flue. Ukukhethwa kwezimoto kulandela imephu yomjikelezo womsebenzi oqinile—ukusebenza kahle kwe-IE3 kujwayelekile, kodwa sicacisa i-IE4 enamadrayivu ashintshashintshayo lapho ukushintshwa komthwalo kudlula u-40% phakathi kokuphakeme nokungenzi lutho. Abakaki abafakwayo bahlanganisa izibonelelo zokunweba ezishisayo ezifika ku-12 mm—okubalulekile lapho kufakwa imigudu yokukhipha umoya kuhnu esebenza endaweni yokushisa engu-280°C.
I-Zibo Hongcheng Fan Co., Ltd. ikhiqiza lawa mayunithi endlini endaweni yayo engu-9,000 m² e-Zibo Blower Industrial Park. Akukho ukukhishwa kwe-subassembly. Wonke ama-impeller athola ukulingana okuguquguqukayo kuya ku-G2.5 ISO 1940-1 ukubekezelelana—okuqinisekiswa ngama-vibrometer alinganisiwe we-laser, hhayi nje amabhalansi aphansi esitolo. Ukuhlola kokugcina kufaka phakathi imizuzu engu-120 yokusebenza komthwalo ogcwele ngesivinini esilinganiselwe esingu-110%, nokuqapha kwesikhathi sangempela sokukhuphuka kwezinga lokushisa (ubukhulu ΔT = 28°C), ukuchezuka kwekesi (<0.12 mm), namazinga e-acoustic emission (<82 dB(A)). Yonke imibiko yokuhlolwa ithunyelwa ngeyunithi. Uzothola imibhalo egcwele yobuchwepheshe—okuhlanganisa imidwebo enobukhulu, imininingwane yetorque, nohlu lokuhlola lokuqalisa—ku hongchengfan.com.I-Inclined Chute Centrifugal Fan
Le khasi Ethambekele emgqonyeni we-chute centrifugal fan ixazulula inkinga elula ngokukhohlisa: ukuhambisa impahla ekhuphukayo ngaphandle kokulahlekelwa ukulawula. Ayithathi indawo yama-conveyor noma iziphakeli ezidlidlizayo. Kubenza basebenze ngokwethembeka. Emisebenzini yezimayini lapho ukumiswa kwe-chute okungahleliwe kubiza u-$18,000/ihora ngesikhathi sokuphumula, noma ezitshalweni zamakhemikhali lapho ukunqwabelana kothuli kubangela ukwephulwa kwe-ATEX, lokhu akuphathelene nokugeleza komoya—kumayelana nokuqhubeka nokusebenza. Njengoba izinqubo zezimboni zikhula zididiyelwe futhi zingathetheleli kangako, indima yabalandeli iyashintsha isuka engxenyeni eyisizayo iye kokwenza uhlelo isebenze. Kungakho sinjiniyela iyunithi ngayinye nge-chute yayo ethile—hhayi ikhasi lekhathalogi.
