Ma centrifugal blower okhala ndi makina amagalimoto amathetsa ululu umodzi wosalekeza: kutaya mphamvu pakulumikizana. Tawona zomera zambiri zikusiya kugwira ntchito bwino kwa 8-12% chifukwa cha kutsetsereka kwa lamba, kusanja bwino, kapena kuvala zonyamula pamagalimoto osalunjika. Ichi ndichifukwa chake zowulutsira molunjika-makamaka zomwe zimapangidwira ntchito yopitilira mafakitale-akhala ngati zida zabata kumbuyo kwa mpweya wokhazikika, kutsika kwa OPEX, komanso kuwongolera njira zolimba.
Chifukwa chiyani Direct-Drive Imamenya Ma Belted kapena Coupled Setups
Kuyendetsa molunjika kumatanthauza kuti shaft ya injini imalumikizana molunjika ku chiwongolero - palibe malamba, palibe zolumikizana, palibe ma shaft apakatikati. Pogwira ntchito zenizeni padziko lapansi, izi zimachotsa ma vectors atatu olephera omwe timawatsata m'malo opumira mpweya wa migodi ndi mizere yopangira mankhwala: kutopa koyambitsa kugwedezeka, kugwedezeka kwapang'onopang'ono pambuyo pa kupalasa njinga zotentha, ndi kutsika kwanthawi yokonza kuchokera pakukonzanso kukangana. A Zibo Hongcheng Fan Co., Ltd. 4-72-11 No.8C zitsulo zosapanga dzimbiri centrifugal blower ndi Integrated 30 kW IE3 motor anayenda maola 14,200 popanda kubala m'malo-pamene mnzake woyendetsedwa ndi lamba pamakina omwewo amafunikira kusintha kokhala ndi kasanu ndi kawiri ndikusintha malamba anayi munthawi yomweyo.
Izi sizongoyerekeza. Direct drive imachepetsa kuwonongeka kwa makina mpaka 2%. Lamba amayendetsa pafupifupi kutayika kwa 5-9%. Ma gearbox? 10-15%. Kusiyanaku kumaphatikizana mwachangu: 75 kW blower yomwe ikuyenda 24/7 pa 80% katundu imapulumutsa ndalama zoposa $2,100/chaka mumagetsi okha posintha kuchoka pa lamba kupita pagalimoto yolunjika-musanayambe kugwira ntchito, zida zosinthira, ndi kuzimitsa kosakonzekera.
Koma kuyendetsa molunjika kumangopereka mtengo ngati mota ndi chotengera zimagwirizana motenthetsa komanso mwamphamvu. Tayesa mayunitsi pomwe ma coefficients owonjezera amafuta osagwirizana adapangitsa kuti ma rotor asokoneze mkati mwa maola 300. Kukonza? Nyumba zophatikizika zamagalimoto zokhala ndi njira zozizilitsira zogawana-ndi zolumikizira zomwe zimayenderana ndi ISO 1940 G2.5 pa liwiro logwira ntchito, osati kungokhazikika.
Zomwe Ogula Amanyalanyaza (ndi Kunong'oneza Bondo Pambuyo pake)
Ena amaganiza kuti "centrifugal blower with motor" amatanthauza pulagi-ndi-play kuphweka. Sizikutero. Zopinga zitatu zobisika zimakweza ngakhale magulu odziwa kugula zinthu:
- Kukhazikika kokhazikika ndikofunikira kuposa torque yovotera. Chigawo chokhala ndi flange papulatifomu yopyapyala yachitsulo chimatumiza ma resonance kukhala ma ductwork - zomwe zimapangitsa kuti kutopa kumang'ambika pafupi ndi zigongono. Timatchula makulidwe oyambira apansi (≥25 mm pamayunitsi opitilira 30 kW) ndipo timafunikira ma grouting pa ISO 10816-3 kalasi ya vibration B.
- Kugwirizana kwa VFD sikungochitika zokha. Si ma motors onse ophatikizika omwe amatha kutsitsa 4: 1 popanda kusokoneza. Ma motors athu okhazikika a IE3 akuphatikiza kutsekereza kwa Class F, kuziziritsa kwa mpweya wokakamiza, ndi ma windings ovotera ndi VFD - koma pokhapokha ngati atchulidwa panthawi yoyitanitsa. Mayunitsi omwe amatumizidwa popanda izi nthawi zambiri amatentha kwambiri pansi pa 35 Hz.
- Kukana kwa dzimbiri kumayambira panyumba yamagalimoto. Zopangira zitsulo zosapanga dzimbiri sizitanthauza kanthu ngati chimango chamotocho chapakidwa chitsulo chofewa. Pa nsanja zam'mphepete mwa nyanja kapena mizere yogwiritsira ntchito chlorine, timagwiritsa ntchito zotchinga zonse za AISI 316L - osati ma gudumu a fan.
Makasitomala omwe amadumpha macheke awa nthawi zambiri amakumana ndi kubweza ndalama zokwana 3 × mtengo woyambirira wa unit. Makasitomala m'modzi wokonza chakudya adalowa m'malo mwa chowulutsira pashelefu molunjika patatha miyezi isanu ndi umodzi chifukwa ma condensation adapangidwa mkati mwa nyumba yopanda mpweya. Yankho lake silinali mtundu watsopano-linali kufotokoza kusindikiza kwa IP66, kukhetsa mpweya, ndi makatiriji amkati a silika a gel.
Kufananiza Chigawo ndi Dongosolo Lanu-Osati Catalog Yokha
"centrifugal blower with motor" sichimasankhidwa ndi mahatchi okha. Imakulitsidwa ndi mphambano yopingasa dongosolo. Timapempha kasitomala aliyense kuti apange mawonekedwe ake enieni a ma duct-osati kukakamiza kokhazikika. Chifukwa chiyani? Chifukwa makina a 1,200 Pa okhala ndi zigongono khumi za 90 ° ndi ma dampers atatu sachita chilichonse ngati njira yowongoka ya 1,200 Pa. Kuwonongeka kwenikweni kwapadziko lonse chifukwa cha chipwirikiti kumatha kuwonjezera 30-50% kupitilira kuwerengetsa mabuku.
Ichi ndichifukwa chake mainjiniya athu amawunika mawu aliwonse motsutsana ndi mfundo zitatu za data: mbiri yoyezera liwiro la inlet, makulidwe azinthu zamakina (ε), komanso kutentha koyipa kwambiri / chinyezi. Mwachitsanzo, 55 kW direct-drive unit ya chowumitsira biomass ku Shandong imayenda pa 1,850 rpm pamalo opangira - koma imatsika mpaka 1,320 rpm munthawi yamvula chifukwa cha kuchuluka kwa mpweya. Popanda malirewo, mayendedwe a mpweya angagwere 12% pansipa.
Timakhala ndi masinthidwe opitilira 600, kuphatikiza mafani a axial flow migodi, mitundu ya polyester yolimba ya magalasi olimba a fiberglass, ndi ma centrifugal ma centrifugal amphamvu kwambiri ofikira 400 ° C. Koma pamagalimoto oyendetsa molunjika, mndandanda wathu womwe timafunsidwa kwambiri ndi mizere ya 4-72-11 ndi G4-73: onse amapereka zolumikizira zokhota kumbuyo (zochita bwino kwambiri 84-87%), nyumba zopangira aluminiyamu, ndi zosankha zamagalimoto kuchokera ku 1.5 kW mpaka 200 kW-ndikutsatira kwathunthu ku GB/T 1230, ISO 1230 ndi kuyesa kwa ISO
Mfundo yofunika kwambiri: Kuchita Bwino Mungathe Kuyeza, Osati Kungonena
Centrifugal blower yokhala ndi mayankho amagalimoto imapereka ROI yoyezeka-osati zonena zamalonda. Amadula kugwiritsa ntchito mphamvu. Iwo amachepetsa kukonza mazenera. Amawonjezera moyo wautumiki pochotsa maulalo ofooka amakina. Koma pokhapokha atapangidwa ngati msonkhano umodzi wozungulira-osati wolumikizidwa pamodzi pambuyo pake.
Zibo Hongcheng Fan Co., Ltd. imamanga mayunitsi a malo omwe kulephera sikungachitike: migodi yapansi panthaka yokhala ndi ngozi zophulika za gasi, mizere ya electroplating yogwira hydrochloric acid mist, ndi ma silo ambewu omwe amafunikira chiphaso chosaphulika. Kalozera wawo amakhala ndi mindandanda yopitilira 50-koma chowombera chapakati pa centrifugal chimakhalabe chosankha chapamwamba kwa ogwiritsa ntchito omwe amatsata kWh, osati kW yokha.
Yang'anani kupitirira chizindikirocho. Yang'anani mawonekedwe otentha pakati pa mota ndi impeller. Tsimikizirani kuti zokwezera zikugwirizana ndi maziko anu, osati kabuku kokha. Fufuzani data ya vibration yodzaza, osati chochita. Kenako mupeza zomwe zimalonjeza molunjika: chete, kukhazikika, ndi kusunga komwe kumawonekera pa mita.
