Kusarudza zvakanaka Centrifugal fan mhando haisi yekufananidza nhamba yekabhuku kune nameplate. Ndezvekugadzirisa dambudziko chairo-kufamba mhepo ichipikisa, kubata utsi hunoparadza, kurarama 200 ° C hova dzemhepo, kana kuchengetedza mugodhi wemarasha uchifefeterwa pasi pemamiriro enjodzi yekuputika. Takakura, takaedza, uye takaraira vanopfuura chiuru nemazana maviri evateveri vecentrifugal kubvira 2020-uye mune zvese, mhando isiriyo yakakonzera kunonoka, kukanganisa kuchengetedza, kana kutadza nguva isati yakwana.
Nei "Type" Inokosha Kupfuura Saizi kana Kumhanya
A 9-19 high-pressure centrifugal blower inofambisa mweya zvakasiyana pane mbiri-inlet centrifugal fan-kunyangwe paRPM yakafanana uye static pressure. Musiyano uri mune impeller geometry, casing dhizaini, uye nzira yekuyerera kwemhepo. Kumashure-yakakomberedzwa impellers inobata guruva-yakatakura flue gasi pasina kuvhara. Forward-curved units inoburitsa yakakwira vhoriyamu pa low static pressure-asi inokundikana nekukasira munzvimbo dzine abrasive. Radial-tip impellers inogara pakati pavo: kushanda zvine mwero, kushivirira kwakanyanya kwezvikamu, uye kupusa kwemuchina uko kunokosha panguva yekugadzirisa munzvimbo dziri kure dzekubira.
Isu takambotsiva yakakundikana kumberi-yakakomberedzwa fani mune yejira yedhayi tambo ine kumashure-yakarerekera modhi. Iyo yekutanga unit yakagara 4 mwedzi. Iyo nyowani yakamhanya mwedzi makumi matatu nemanomwe-isina inotsiviwa, isina kutsvedza bhandi, hapana kudonha kwemhepo. Sei? Nekuti iyo application yaida yakaderera mhirizhonga, kwete yakanyanya CFM. Ndiwo mutemo wekutanga: fananidza ne type ku hunhu hwemhepo, kwete chati chete.
Iwo mana Core Centrifugal Fan Types-Uye Kwadzinokundikana
Vashandisi veindasitiri havadi zvikamu zvedzidzo. Vanoda sarudzo logic. Hezvino izvo zvinoshanda-uye apo mhando yega yega inoputsika:
- Backward-curved (BC) mafeni: Yakanakisa kune yakakwirira-static, yepamusoro-tembiricha, kana corrosive sevhisi-senge desulfurization stacks kana boiler primary air. Impeller blades inokona kure nekutenderera. Kubudirira kunowedzera pa82-87%. Asi ivo vanoda kurongeka kwakaringana; misaligned ductwork inokonzera kudedera kunotsemura dzimba. Yedu BC modhi (semuenzaniso, anti-corrosion akasiyana ane FRP-akavharwa casings) anosanganisira laser-aligned inlet cones seyakajairwa.
- Forward-curved (FC) mafeni: Yakakwana, yakanyarara, uye yakakwirira-vhoriyamu pakudzikira-yakanakira HVAC make-up mhepo kana yakachena mukamuri recirculation. Asi ivo vanomira nyore pamusoro pe150 Pa static pressure. Takaona matatu maFC mayuniti achikundikana mumakemikari chirimwa chekugadzirisa mitsara yekudzoreredza nekuti vashandisi vakafuratira kukwirisa-kusimuka curve. Izvo hazvina kugadzirirwa kusiyanisa kuramba.
- Radial-tip (RT) mafeni: Mabhiza ebasa rine huruva, mwando, kana kuti rinokuvadza zvinyoro—kupinza mhepo mumigodhi, kutonhodza, mhepo yemoto inotenderera. Mablades anotambanuka akananga kunze, achiramba kuvaka. Kuderera kwepamusoro kwepamusoro (72-78%) inotengeswa kuti ivimbike. Mune imwe metallurgical client's sinter inotonhorera application, RT mafeni akacheka isina kurongeka yekudzikira ne63% kupesana neBC dzimwe nzira.
- Dual-inlet centrifugal mafeni: Mapopu maviri pane imwe shaft, achikwevera mweya kubva kumativi ese. Inopa yakaenzana kuyerera pasina duct asymmetry. Yakakosha apo nzvimbo yakamanikana asi mafambiro emhepo anofanirwa kugara akatsiga-senge tunnel yekufefetera ma portals kana denga-rakakwira chiutsi exhaust masisitimu. Nekudaro, ivo vanoda rigid base mounting. Iyo 2 mm hwaro shanduko yakakonzera resonance mupurojekiti ichangoburwa kudzamara tawedzera shear-resistant anchor pads.
Izvo iyo Catalog isingakuudze iwe
Vamwe vanogona kukakavara kuti kusarudzwa kwezvinhu kune impeller mhando. Asi isu takaona mafani etitanium ane corrosion akasimba kuramba achitadza nekuti iyo yekumashure-yakakomberedzwa impeller haigone kubata nhunzi inorodha. Type inotsanangura fizikisi. Material inotsanangura hwindo rekupona.
Chokwadi matatu akaoma kubva kumunda data:
- Pressure curves nhema. Fani yakaverengerwa "12 kPa @ 25,000 m³/h" inotora mamiriro ekupinda mukati. Real-world duct magokora, madhamu, uye mafirita anodonhedza kuita chaiko ne12-18%. Gara uchiyedza padanho rehurongwa-kwete chete fan-chete.
- Certification-proof certification (e.g., dⅠ yemigodhi yemarasha) inoshanda pakuungana kwakazara-kwete mota chete. Motokari yakasimbiswa yakavharirwa kune isina-certified imba inovharisa kutevedza. Yedu FBD yakatevedzana yekubatanidza inosanganisira spark-inodzivirira impeller clearances uye yakadzika static nzira dzakasimbiswa paGB 3836.1.
- Dynamic balancing haisi sarudzo. Vasina kuenzanisa BC mafeni anozunguzika pa1,450 RPM. Pa2,900 RPM, kusaenzana kumwe chete kunowedzera simba zvakapetwa kana. Yese Hongcheng centrifugal fan inopinda ISO 1940 G2.5 kuenzanisa-yakayerwa, isingafungidzirwe.
Maitiro Ekusarudza-A Maminetsi mashanu Munda Wekutarisa
Usati wavhura pepa, pindura iyi mibvunzo mishanu:
- Chii chii yakanyanya kusimbiswa static pressure-kwete peak, kwete theoretical? Zviyere ne manometer pane fan inlet, pasi pemutoro wakazara.
- Ko mhepo ine mhepo abrasives, mwando, kana makemikari? Kana hongu, bvisa mberi-curved. Rongedza radial-tip kana kumashure-yakakomberedzwa ine zvinodzivirira.
- Is nzvimbo yakamanikidzika? Dual-inlet inochengetedza tsoka asi inoda kusimba kwechimiro. Imwe-inlet ine yakawedzera inlet cone inogona kuve nyore.
- Vafambisi vachagadzirisa kuyerera nguva nenguva here? Backward-curved inobata throttling zvirinani. Forward-curved surges zvisingatarisike pazasi 60% kumhanya.
- Chii chii kukundikana mutengo? Kuvhara muimba yebhailer kunodhura $ 18,000 / awa. Bhadhara kumberi-kumashure-yakakomberedzwa + yakasanganiswa yekudziya yekutarisa-kwete gare gare kugadzirisa kwekukurumidzira.
Mhando dze Centrifugal fan hadzisi zvikamu zvinochinjika. Ivo vakagadziridzwa mhinduro kune zvipingaidzo zvemuviri. Sarudza rudzi runoremekedza mhepo yako, nharaunda yako, uye nguva yako yaunovavarira—kwete iyo ine bhurocha rinopenya zvikuru.
