Kusankha choyenera mafakitale axial flow fan siziri za kusankha chokweza kwambiri kapena chachikulu kwambiri. Ndi za kufananiza kuyenda kwa mpweya, kupanikizika, ndi kulimba kwa chilengedwe ndi ndondomeko yanu-osati kuwononga ndalama zambiri pazomwe mumapangidwira, osati kufotokoza mochepa ndi kuyang'anizana ndi nthawi yotsika, kutentha kwambiri, kapena kulephera kwa chitetezo. Taziwona nthawi zambiri: makina oyendetsa mpweya wa migodi amatsekedwa chifukwa kupanikizika kwa static kunali kolakwika ndi 12%; chomera chamankhwala m'malo mwa mafani atatu m'miyezi 18 chifukwa cha dzimbiri chomwe sichinanyalanyazidwe pakusankhidwa; nyumba yowotchera imataya kuyaka bwino ndi 8% mutayika chowotcha cha axial chomwe sichingafanane ndi phula ndi liwiro la ma ducts.
Yambani ndi Dongosolo-Osati Zokupizira
Mafani a axial flow a Industrial axial amasuntha mpweya kufananiza ndi shaft. Kuphweka kumeneko kumabisa zovuta. Kuchita kwawo kumagwa mwachangu akayikidwa mosaganizira za chipwirikiti cholowera, kukana kutulutsa, kapena malo ozungulira. Musanafananize RPM kapena motor kW, yankhani mafunso asanu otsimikizika awa:
- Kodi static pressure ikufunika bwanji? Osalemba ma curve a "mpweya waulere" - kuyeza kukana kwathunthu kwa makina ndi zotchingira zotsekedwa, zigono zimawerengedwa, zosefera zodzaza, ndi ma ducts pamapangidwe. A 500 Pa spec pamapepala nthawi zambiri imakhala 720 Pa ikugwira ntchito.
- Kodi mpweya wocheperako ndi wotani—ndipo pa kutentha kotani, chinyezi, ndi katundu wotani? Mafani a Axial amatsitsa mphamvu ya 30-40% pamwamba pa 60 ° C pokhapokha ngati masamba ndi ma bere amavotera. Pogwira malasha, 20 g/m³ kuthira fumbi kumafuna ma berelo omata ndi zokutira zosamva ma abrasion—osati utoto wamba.
- Kodi kuphulika kulipo? M'migodi ya malasha, zosungunulira zosungunulira, kapena nkhokwe zambewu, "umboni wa kuphulika" siwosankha-ndizosakambirana. Chitsimikizo chiyenera kugwirizana ndi kagawo ka madera (mwachitsanzo, Ex dⅠ ya zone zapansi panthaka zokhala ndi methane), osati kungolemba zilembo zamagalimoto.
- Kodi kukonzanso kudzakhudza bwanji nthawi yowonjezera? Wokupiza yemwe amasunga $1,200 kutsogolo koma amafunikira disassembly yathunthu kuti alowe m'malo mwake amawononga $18,000/chaka pogwira ntchito komanso kutayika.
- Kodi "kulephera" kumatanthawuza chiyani pakugwiritsa ntchito kwanu? Ndi kugwedezeka> 4.5 mm/s RMS? Kodi ndi 5% kutsika kwa mpweya pa miyezi 12? Kodi ndikulephera kuyambiranso pambuyo pa maola 48 akudikirira? Tanthauzirani metric musanasankhe.
Osakhulupirira Ma Curve a Catalog Pawokha
Tinayesa mafani a axial flow 14 mbali ndi mbali muchipinda choyezera. Onse adakumana ndi mpweya wodziwikiratu pa zero static pressure-koma 3 yokha idapereka ≥92% yamayendedwe ovotera pa 400 Pa static. Chifukwa chiyani? Zifukwa ziwiri: kusayenda bwino kwa malo olowera komanso kutsetsereka kosalongosoka kwagalimoto pakalemedwa pang'ono. Kukhazikitsa kwapadziko lonse lapansi sikumakhala ndi njira zowongoka komanso zoyera. Ngati zimakupizani zikukhala kumbuyo kwa chigongono cha 90 ° kapena mkati mwa plenum yopapatiza, yembekezerani kutsika kwa 15-25% kuposa momwe ma curve osindikizira amanenera. Nthawi zonse gwiritsani ntchito 20% yochepetsera pokhapokha mutatengera njira yolowera kapena kuyika cholowa chovomerezeka.
Onaninso kuchotsedwa kwa nsonga za tsamba. Kusiyana kwa 2 mm pa fani ya 1,200 mm m'mimba mwake kumadula mphamvu ndi 7%. Malo opangidwa ndi makina olondola ndi ma rotor ogwirizana ndi laser sizinthu zamtengo wapatali-ndimo momwe Zibo Hongcheng Fan Co., Ltd. imasungira ± 1.5% kusinthasintha kwa mpweya pamitundu yonse ya FBD yotsatizana, ngakhale pambuyo pa maola 10,000 ogwira ntchito.
Zinthu Zakuthupi ndi Zomangamanga Zisankha Utali Wa Moyo—Osati Mtengo Wokha
Chokupizira cha $2,800 chomangidwa ndi malata azitsulo, masamba okhazikika achitsulo, ndi ma motors a IP54 amatha zaka 2-3 muutsi wamankhwala wam'mphepete mwa nyanja. Mpweya womwewo wochokera ku unit ya $4,100 yokhala ndi titaniyamu alloy masamba, ma epoxy-coated casings, ndi ma IP68-proof-proof motors amapitilira zaka 12 pamenepo. Kuwonongeka sikumadzilengeza - kumayamba ngati kubisala kosawoneka ndi maso, kenako kumathamanga kwambiri kamodzi ma chloride ions aphwanya gawo lapansi.
Kulinganiza kwamphamvu kumakhudzanso chimodzimodzi. Ma rotor osagwirizana amayambitsa kutopa, kumveka kwa chimango, ndi kulephera kusindikiza msanga. Ku Zibo Hongcheng Fan Co., Ltd., rotor iliyonse ya axial fan imadutsa pawiri-ndege kusanja mpaka G2.5 giredi pa ISO 1940-kutsimikiziridwa ndi kuyesa kugwedezeka kwamoyo pa 110% liwiro lalikulu. Ichi ndichifukwa chake mitundu yawo ya 9-19 yochokera ku axial imakhala yokhazikika pa 0.28 mm/s RMS vibration ngakhale patatha zaka 5 mumizere yozizirira ya ng'anjo yozungulira.
Kusintha Mwamakonda Sizinthu Zapamwamba-Ndi Kuchepetsa Ngozi
Ena angatsutse kuti: “Mafani wamba ndi otsika mtengo komanso othamanga.” Koma pamene mpweya wanu wolowera mu ngalandeyo ukufunika kusinthasintha mobwereranso pakufunika, scrubber yanu ya desulfurization imafunika 100% kukana dzimbiri pa 85°C wonyowa babubu, kapena utsi wa ng'anjo wanu wazitsulo umanyamula 350 ° C - simusintha ndondomekoyi kuti igwirizane ndi fani. Mumafotokozera fan ku ndondomekoyi.
Zibo Hongcheng Fan Co., Ltd mafakitale axial flow fan zothetsera mkati mwa masabata 4-6 - osati miyezi - chifukwa makina, kusanja, ndi kuyesa kumachitika pansi pa denga limodzi. Apereka mafani a FBD okhala ndi ma windings awiri-voltage (380V/660V), masensa otenthetsera ophatikizika okhala ndi Modbus RTU kutulutsa, ndi nyumba zosaphulika zomwe zidavotera Zone 1 ndi Zone 21 nthawi imodzi — zonse popanda kukulitsa nthawi yotsogolera kapena kusokoneza zolemba za QA.
Chomaliza Chomaliza: Funsani Wopereka Wanu Mafunso Atatu Awa
Asanamalize chilichonse mafakitale axial flow fan kugula, funsani:
- "Kodi mungandipatse malipoti a chipani chachitatu - osayinidwa ndikudindidwa - pazachitsanzo chenichenichi, malinga ndi kukakamizidwa kwanga kokhazikika?"
- "Kodi nthawi yanu yolembedwa ndi yotani pakati pa zolephera (MTBF) pakusintha kumeneku pamapulogalamu ofananira ndi anga?"
- "Kodi mumapereka chithandizo chothandizira patsamba - kuphatikiza kutsimikizira kwakuyenda kwa mpweya komanso kujambula koyambira?"
Ngati yankho liri losavuta, lachedwa, kapena "tiyang'ana," chokanipo. Kuyenda kwa mpweya wodalirika sikugulitsidwa - kumapangidwa, kutsimikiziridwa, ndi kuthandizidwa. Pachimake, kuchita bwino kwambiri kumatanthauza kusagwirizana pachitetezo, palibe mtengo wobisika wamoyo, komanso osadabwitsa poyambitsa. Kumeneko si malonda. Umu ndi momwe mafani amathamangira kwa zaka 15 mu mgodi wa malasha—ndipo amapitabe kuunika.
