I-centrifugal blower enamasistimu ezimoto ixazulula iphuzu elilodwa lobuhlungu eliqhubekayo: ukulahlekelwa amandla ekuhlanganisweni. Sibone izitshalo eziningi kakhulu zilahlekelwa ukusebenza kahle okungu-8–12% ngenxa nje yokushelela kwebhande, ukungaboni ngaso linye, noma ukuguga kwezimpahla ekusethweni kwedrayivu engaqondile. Kungakho ama-direct-drive centrifugal blower-ikakhulukazi lawo akhelwe umsebenzi oqhubekayo wezimboni-sephenduke izisebenzi ezithule ngemuva kokugeleza komoya okuzinzile, i-OPEX ephansi, kanye nokulawula inqubo okuqinile.
Kungani I-Direct-Drive Ishaya Ukusetha Okuhlanganisiwe noma Okuhlanganisiwe
I-Direct-drive isho ukuthi i-motor shaft ixhuma ngqo ku-impeller hub-awekho amabhande, awekho ama-couplings, awekho amashafti aphakathi nendawo. Ekusebenzeni komhlaba wangempela, lokhu kuqeda ama-vector amathathu ahlulekayo esiwalandela kuzo zonke izizinda zokungenisa umoya ezimayini kanye nemigqa yokucubungula amakhemikhali: ukukhathala okubangelwa ukudlidliza, ukukhukhuleka kokuqondisa ngemva kokuhamba ngebhayisikili elishisayo, kanye nesikhathi sokuphumula sokulungisa kusukela ekulungiseni kabusha ukucindezeleka. I-Zibo Hongcheng Fan Co., Ltd. 4-72-11 No.8C insimbi engagqwali yokufutha i-centrifugal enenjini ehlanganisiwe engu-30 kW IE3 isebenze amahora angu-14,200 ngaphandle kokushintshwa—kuyilapho uzakwabo oshayelwa ibhande ohlelweni olufanayo lwepayipi idinga izinguquko eziyisikhombisa nokushintshwa kwamabhande amane ngesikhathi esifanayo.
Lokhu akulona ithiyori. Ukushayela okuqondile kunciphisa ukulahleka kwemishini kube ngaphansi kuka-2%. Ibhande lishayela isilinganiso sokulahlekelwa okungu-5–9%. Amabhokisi ogiya? 10–15%. Lowo mehluko uhlangana ngokushesha: i-75 kW blower enamandla angu-24/7 ngomthwalo ongu-80% yonga ngaphezu kuka-$2,100/ngonyaka kugesi kuphela uma ushintsha usuka ebhandeni uye kumshayeli oqondile—ngaphambi kokufakwa kwezabasebenzi, izingxenye eziyisipele, nokuvalwa okungahleliwe.
Kodwa idrayivu eqondile iletha inani kuphela uma i-motor ne-impeller kuhambisana ngokushisa kanye namandla. Sihlole amayunithi lapho ama-coefficients okunwebeka okushisayo angafani abangele ukuhlikihla kwe-rotor phakathi namahora angu-300. Ukulungisa? Izindlu zezimoto ezididiyelwe ezinezindlela zokupholisa ezabiwe—kanye nezigxivizo ezilinganiselwe ku-ISO 1940 G2.5 ngesivinini sokusebenza, hhayi nje ibhalansi emile.
Lokho Abathengi Abakubukayo (futhi Bazisole Kamuva)
Abanye bacabanga ukuthi “i-centrifugal blower enenjini” isho ukuxhuma nokudlala kalula. Ayikwenzi. Izithiyo ezintathu ezifihliwe zikhuphula ngisho namaqembu okuthenga anolwazi:
- Ukukhweza ukuqina kubaluleke ngaphezu kwe-torque elinganiselwe. Iyunithi efakwe nge-flange kuplathifomu yensimbi ezacile izodlulisela i-resonance ku-ductwork-okubangela ukuqhekeka kokukhathala eduze nezindololwane. Sicacisa ubuncane bokujiya kwepuleti lesisekelo (≥25 mm kumayunithi angaphezu kuka-30 kW) futhi sidinga i-grouting ngesigaba ngasinye sokudlidliza se-ISO 10816-3 B.
- Ukuhambisana kwe-VFD akuzenzeki. Akuwona wonke ama-motor ahlanganisiwe abamba i-4: 1 turndown ngaphandle kokunciphisa. Amamotho ethu ajwayelekile e-IE3 ahlanganisa ukufakwa kwe-Class F, ukupholisa komoya ngempoqo, namawindi alinganiswe nge-VFD—kodwa kuphela uma ecaciswe esigabeni soku-oda. Amayunithi athunyelwa ngaphandle kwaleyo ncazelo avame ukushisa ngaphansi kuka-35 Hz.
- Ukumelana nokugqwala kuqala endaweni yemoto. Ama-impeller ensimbi engagqwali awasho lutho uma uhlaka lwemoto lupendwe ngensimbi ethambile. Kumapulatifomu angasogwini noma emigqeni yokubamba i-chlorine, sisebenzisa izivalo ezigcwele ze-AISI 316L—hhayi nje isondo labalandeli.
Amakhasimende eqa lawa masheke ngokuvamile abhekana ne-retrofit kubiza 3× inani langempela leyunithi. Iklayenti elilodwa elilungisa ukudla lithathe indawo ye-off-the-shelf direct-drive blower ngemva kwezinyanga eziyisithupha ngenxa yokuthi ukufingqa kwakheke ngaphakathi kwendlu yenjini engangeni. Isixazululo kwakungelona uhlobo olusha—besicacisa ukuvalwa kwe-IP66, ama-drain vents, nama-cartridge ejeli ye-silica yangaphakathi.
Ukufanisa Iyunithi Nohlelo Lwakho—Hhayi Ikhathalogi Kuphela
"I-centrifugal blower enenjini" ayikhethwa ngamandla ehhashi kuphela. Ilinganiswe ngokuphambana kwejika lejika lesistimu. Sicela wonke amakhasimende ngesakhiwo sawo samapayipi—hhayi nje ingcindezi egxilile. Kungani? Ngoba isistimu ye-1,200 Pa enezindololwane eziyishumi ze-90 ° kanye nama-dampers amathathu aziphathi lutho njenge-1,200 Pa eqondile egijima. Ukulahlekelwa komhlaba wangempela okuvela ezinxushunxushwini kungangeza u-30–50% ngaphezu kwezibalo zezincwadi.
Kungakho onjiniyela bethu behlola ikhwothi ngayinye beqhathanisa namaphoyinti edatha amathathu: iphrofayili ye-inlet velocity elinganisiwe, ukushuba kwempahla ye-duct (ε), kanye nezinga lokushisa elibi kakhulu/umswakama. Isibonelo, iyunithi yokushayela eqondile engu-55 kW yomshini wokomisa i-biomass e-Shandong isebenza ngo-1,850 rpm endaweni yokuklama—kodwa yehla iye ku-1,320 rpm phakathi nenkathi yezimvula ngenxa yobuningi bomoya. Ngaphandle kwaleyo majini, ukuhamba komoya kuzokwehla ngo-12% ngaphansi kokucaciswa.
Sigcina izilungiselelo ezingaphezu kuka-600—okuhlanganisa amafeni okugeleza kwe-axial yezimayini, amamodeli e-fiberglass-reinforced polyester, kanye nama-ventilators abamba ukushisa okukhulu okuphakathi alinganiselwe ku-400°C. Kodwa ezinhlelweni zokushayela okuqondile, uchungechunge lwethu oluceliwe kakhulu yilayini engu-4-72-11 kanye ne-G4-73: yomibili inikezela ngezigxivizo ezigobe emuva (ukusebenza kahle okuphezulu okungu-84–87%), izindlu ze-aluminium eziphonswayo, kanye nezinketho zemoto kusuka ku-1.5 kW kuya ku-200 kW—ngokuhambisana ngokugcwele ne-GB/T 1230, ISO 1230, ISO 1230 AM kanye ne-ISO 1230 yokuhlola.
Iphuzu Elibalulekile: Ukusebenza Ngempumelelo Ongakukala, Hhayi Ukumangalela Nje
I-Centrifugal blower enezixazululo zemoto iletha i-ROI elinganisekayo—hhayi izimangalo zokumaketha. Banciphisa ukusetshenziswa kwamandla. Bashwabanisa amafasitela okunakekela. Banweba impilo yesevisi ngokususa izixhumanisi ezibuthakathaka ezisebenza ngomshini. Kodwa kuphela lapho iklanywe njengomhlangano owodwa ojikelezayo-hhayi ohlanganiswe ndawonye ngemva kweqiniso.
I-Zibo Hongcheng Fan Co., Ltd. yakha lawa mayunithi ezindaweni lapho ukwehluleka kungeyona inketho: izimayini ezingaphansi komhlaba ezinezingozi zegesi yokuqhuma, imigqa ye-electroplating ephatha inkungu ye-hydrochloric acid, nezisele zokusanhlamvu ezidinga isitifiketi sokuvikela ukuqhuma. Ikhathalogi yabo ihlanganisa uchungechunge olungaphezu kuka-50—kodwa isivutheli se-centrifugal esidonsa ngokuqondile sihlala siyinketho ephezulu kubasebenzisi abalandelela i-kWh, hhayi nje i-kW.
Bheka ngale kwelebula. Hlola isikhombimsebenzisi esishisayo phakathi kwe-motor ne-impeller. Qinisekisa ukuthi imininingwane yokukhweza ifana nesisekelo sakho—hhayi nje incwajana. Funa idatha yokudlidliza ngokulayisha ngokugcwele, hhayi ukungenzi lutho. Khona-ke uzothola ukuthi idrayivu eqondile ithembisa ini: ukuthula, ukuzinza, nokonga okubonakala kumitha.
