Mtengo wa centrifugal exhaust fan blower si nambala chabe papepala la mawu. Ndiwo mphambano ya kulondola kwa kayendedwe ka mpweya, kulimba kwa zinthu, kuyendetsa bwino kwa magalimoto, ndi zochitika zenizeni padziko lapansi. Tawonapo ogula akulipira 22% yowonjezerapo kuti agulitse "premium" - kungoyisintha m'miyezi 18 chifukwa nyumbayo idachita dzimbiri munjira yachinyontho ya fakitale yamankhwala. Tawonanso ena akuchepetsa mtengo ndi 35% - ndikutaya $ 4,200 pamwezi pakuchepetsa kupanga pomwe kupanikizika kosasunthika kudatsika ndi 17%. Mtengo ndiwofunikira-koma pokhapokha ngati umagwirizana ndi magwiridwe antchito, nkhani, ndi mtengo wathunthu wa umwini.
Zomwe Zimayendetsa Mtengo wa Centrifugal Exhaust Fan Blower Price
Zinthu zitatu zimayang'anira mitengo - ndipo ziwiri mwa izo siziwoneka papepala.
- Mphepete mwa airflow ndi pressure design margin: Wokupiza wovotera 12,000 m³/h pa 1,800 Pa simtengo wofanana ndi wopereka voliyumu yofanana pa 2,200 Pa. Chotsatiracho chimafuna mbali yotalikirapo ya blade, chilolezo cholimba cha volute, ndi mayendedwe apamwamba-kuwonjezera 18-26% ku mtengo woyambira. M'mayeso athu a labu, mafani okhala ndi malire a ≤3% adalephera kutsimikizira kutentha pansi pakugwira ntchito kosalekeza kwa 40 ° C.
- Umphumphu wa dongosolo la zinthu: Chitsulo chosapanga dzimbiri (304 vs. 316) sichikhudza kukana kwa dzimbiri kokha. Zimakhudza kuwotcherera, kukulitsa kwamafuta kusagwirizana ndi zokwera zamagalimoto, komanso kugwedera kwanthawi yayitali. Chosindikizira cha 316SS chokhala ndi chosindikizira cha laser-welded ndi chosindikizira cha ceramic-chokutidwa ndi shaft chimawononga 41% kuposa 304 yofanana ndi 304-koma chimatenga nthawi yayitali 3.2 × muutsi wothira wamadzi otayidwa ndi chlorine.
- Kuphatikizika kwa magalimoto: Ma injini a IE3 amawonjezera ~ 12% kuposa IE2. Koma ma windings okonzeka a VFD, kutsekereza kwa Class H, ndi IP55+ kukankhira mpanda kumawononganso 9-15%. Timatsata zomwe zili m'munda: mayunitsi okhala ndi makina olumikizana ndi ma motor-fan (palibe lamba, palibe kulumikizana) akuwonetsa zolephera zochepera 29% muzopika zazaka zisanu.
Izi siziri kusiyana kwamalingaliro. Amayezedwa mu maola ogwira ntchito yokonza, kutseka kosakonzekera, ndi kuwerengera mita ya mphamvu. Mtengo wa $1,850 centrifugal exhaust fan blower umawoneka wokongola-mpaka injini yake imakoka 8.7 kW m'malo mwa 7.2 kW yomwe idalonjezedwa pakuyenda kwake. Ndi $1,040/chaka chowonjezera mumagetsi pa $0.12/kWh.
Chifukwa chiyani “Mtengo Wotsikitsitsa” Nthawi zambiri Umakhala Wokwera—Ndipo Mmene Mungaupewere
Ogula ena amapempha ndalama kuchokera kwa ogulitsa asanu, ndiyeno amapereka mphoto kwa otsika kwambiri. Tawunikanso ma projekiti 47 otere pazaka zitatu zapitazi. M'milandu 31, wopambanayo adalowa m'malo mwa chitsulo chopimira chocheperako, giredi yotsika, kapena sanasiyire kusanja kwamphamvu. Zotsatira zake? 68% amafunikira kusungitsanso zinthu mkati mwa masiku 90. Wogula chakudya m'modzi adalowa m'malo mwa mayunitsi onse 12 patatha miyezi isanu ndi umodzi - fumbi lawo la ufa linali litang'ambika ndi aluminiyamu osakutidwa mpaka kukhuthala kwa mamilimita 0.8.
Izi ndi zomwe zimagwira ntchito m'malo mwake:
- Pamafunika ISO 1940-1 G2.5 kusanja certification, osati “kulinganiza” chabe. Timayesa fani iliyonse ya centrifugal exhaust tisanatumize-ndi matalikidwe a log, gawo, ndi malo owongolera.
- Tchulani makulidwe azinthu zochepa: mwachitsanzo, “Casing ≥3.0 mm SS316, impeller ≥4.5 mm, mbale yothandizira galimoto ≥6.0 mm.” Zopindika zachitsulo zopyapyala. Kusinthasintha kumayambitsa ming'alu ya kutopa-ndipo phokoso limakwera pamwamba pa 82 dB (A).
- Tsimikizirani data ya nameplate yamagalimoto ikugwirizana ndi ntchito ya fan. Osati "IE3" yokha. Tsimikizirani ma amps enieni odzaza, chinthu chothandizira (1.15 osachepera), ndi gulu lachitetezo chamafuta. Tapeza 14% ya zinthu zotsika mtengo zomwe zimachokera kunja kwa mislabel service factor kuti iwonjezere kuchuluka komwe kumawonekera.
Kulanga kumeneku kumawonjezera 3-7% ku mtengo wapamwamba—koma kumachepetsa TCO yazaka 5 ndi 22–39%, kutengera kusanthula kwa moyo wamakasitomala.
Zibo Hongcheng Fan Co., Ltd.: Kumene Kulondola Kwaukadaulo Kumakumana ndi Mitengo Yowonekera
Zibo Hongcheng Fan Co., Ltd. imapanga zoposa 600 centrifugal fan fan pa 50+ mndandanda-kuphatikizapo migodi-high-static mayunitsi mayunitsi, zosiyanasiyana kuphulika kuti zisungunuke zosungunulira, ndi aloyi awiri mafani pogwira gasi asidi. Ma centrifugal ventilators awo osapanga dzimbiri amagwiritsa ntchito ma 316L omwe amakhala ozizira okhala ndi ma seams opangidwa ndi TIG komanso ma nitrogen oyeretsedwa mkati - omwe amatsimikiziridwa ndi kuyezetsa kwa utsi wamchere mpaka maola 1,500.
Tayika mtundu wawo wa HC-CF-2250/2000 m'mizere itatu yoyanika ya batri. Chigawo chilichonse chimapereka 8,600 m³/h pa 2,150 Pa static pressure, pogwiritsa ntchito injini ya IE4 yolumikizana mwachindunji yokhala ndi mayankho ophatikizika a encoder. Munda wapakati MTBF: maola 41,200. Mtengo wawo wotulutsidwa wa centrifugal exhaust fan blower umaphatikizanso malipoti oyeserera afakitale-osati ma curve oyenda mpweya, koma mawonekedwe onjenjemera, mamapu amphamvu zamawu, ndi ma torque-vs-liwiro.
Palibe "kuyambira pa" zotsutsa. Palibe zolipiritsa zobisika zamabulaketi okwera, mabokosi okwera, kapena masikelo. Mawu aliwonse amatchula nambala zachitsanzo, cert zakuthupi, ndi miyezo yoyesera yogwiritsidwa ntchito—ASTM A240, ISO 5801, AMCA 210.
Ndondomeko Yanu Yogwirira Ntchito: Kuchokera ku Quote kupita ku Ntchito Yodalirika
Osafanizira mitengo. Yerekezerani umboni.
- Funsani malipoti osinthasintha-osati "kulinganiza kochitidwa." Fufuzani deta ya accelerometer yaiwisi yosonyeza kusalinganika kotsalira ≤2.5 mm/s RMS pa liwiro la ntchito.
- Funsani malipoti a mayeso a mphero kwa casing, impeller, ndi shaft-kutsimikizira kulimba kwamphamvu, zokolola, ndi kapangidwe kakemiko kumafanana ndi ASTM kapena EN specs.
- Yesani unit imodzi musanayambe kuyitanitsa zambiri. Ikani pa ma ductwork anu enieni, ndi mbiri yanu yeniyeni ya static pressure. Log amperage, kutentha kwa pamwamba, ndi phokoso pa 25%, 50%, 75%, ndi 100% liwiro kwa maola 72 otsatizana.
