Forward Curved Motorized Impeller
Kana tatsanangura mwero wekuyerera kwevhoriyamu yatinoda, ingave iri yekupa mweya mutsva kana kutonhora kwemaitiro, isu tinofanirwa kusanganisa izvi nekupokana kuyerera kuchazosangana nefeni mukushandisa.Huwandu hwekuyerera kwevhoriyamu, (mum3 / hr) uye kudzvanywa (muPascals - Pa), zvakabatanidzwa kuti ive nzvimbo yebasa iyo fan inofanirwa kushanda nayo.Izvo zvakakosha kuti isu tisarudze feni ine maitiro ekuita inosangana neinodiwa yebasa pane kana padyo nenzvimbo yekunyanya kushanda.Kushandisa feni pakunyatsoita kwayo kunoderedza mashandisirwo emagetsi uye ruzha rwunobudiswa kubva kune feni ichiunza kuita kunodiwa.
Forward Curved Centrifugal Fan inoshanda sei?
Zita rekuti, 'Centrifugal Fan' rinotorwa kubva kudivi rekuyerera uye mapindiro anoita mhepo paidziri mune axial direction yozofambiswa kunze kubva kunze kwedenderedzwa refani.Musiyano wekuyerera kwegwara pakati pemberi nekumashure curved centrifugal fan ndiyo nzira iyo mhepo inobuda nayo impeller circumference.Nekumashure kwakakomberedzwa impeller, mhepo inobuda munzira yeradial nepo ine mberi yakakomberedzwa mhepo inobuda zvine tangentially kubva padenderedzwa refani.
Iyo yekumberi yakakomberedzwa centrifugal fan inoratidzwa nechimiro chayo checylindrical uye akawanda madiki mablades padenderedzwa reiyo impeller.Mumuenzaniso unoratidzwa pazasi, fan inotenderera ichienda kune wachi.
Kusiyana neyekumashure yakakomberedzwa, chinopenesa chemberi chakakombama chinoda imba inoshandura mhepo yekumhanya ichisiya matipi eblade kuita yakaderera velocity static simba.Chimiro cheimba yacho zvakare chinotungamira kuyerera kwemhepo kune yekubuda.Urwu rudzi rweimba yefeni inowanzozivikanwa semupumburu;zvisinei, inogona zvakare kunzi sevolute kana sirocco imba.Nekuisa iyo yekumberi yakakomberedzwa impeller mumipumburu imba, isu tinowanzo kunongedzera kwairi seyekumberi kwakakomberedzwa kuvhuvhuta.
Kune mhando mbiri dzemafuridziro anoshandisa yekumberi yakakomberedzwa impeller sezvinoratidzwa pazasi…
Iyo imwe inlet blower kuruboshwe, inokwevera mumhepo kubva kune rimwe divi reimba kuburikidza neinotenderedza inlet uye inotungamira kune yakaenzana yekubuda, (inoonekwa pano ine inokwira flange).Iyo kaviri inlet blower ine yakafara mupumburu weimba inokwevera mweya mukati kubva kumativi ese emupumburu ichiuendesa kune yakafara sikweya yekubuda.
Sezvinoita kuseri kwakakomberedzwa centrifugal fan, rutivi rwekusveta rweimpeller blade runokwevera mweya kubva pakati pefani izvo zvinoita kuti pave neshanduko inotungamira yekuyerera kwemhepo pakati peinopinza uye kupera kwe90o.
Fan Characteristic
Iyo yakakwana nzvimbo yekushanda yekumberi yakakomberedzwa centrifugal fan ndeye kana iri kushanda nepamusoro-soro.Iyo yekumberi yakakomberedzwa centrifugal fan inoshanda zvakanyanya kana madzvinyiriro akakwira achipesana nekuyerera kwevhoriyamu yakaderera ichidikanwa.Girafu iri pazasi inoratidza iyo yakanyanya kunaka nzvimbo yekushanda…
Kuyerera kwevhoriyamu kwakarongwa pamwe neX-axis uye iyo system yekumanikidza inorongwa paY-axis.Kana pasina kudzvanywa muhurongwa, (fani iri kuvhuvhuta zvakasununguka), kumberi kwakakomberedzwa centrifugal fan inoburitsa yakanyanya kuyerera yevhoriyamu.Sezvo kupikisa kuyerera kunoshandiswa kune kusveta kana kupera kwedivi re fan, vhoriyamu inoyerera inodonha.
Kuchenjerera kunofanirwa kushandiswa pakusarudza chinofuridza chemberi chakakomberedzwa kuti chishande pane zvakaderera uye nekuyerera kwevhoriyamu yepamusoro.Panguva ino, impeller iri kushanda mune aerodynamic stall nenzira imwechete seaxial fan inoshanda munzvimbo yesadhi yecurve yayo.Panguva ino ruzha uye mashandisirwo emagetsi zvichange zvanyanya nekuda kwemhirizhonga.
Kubudirira kwepamusoro kuri pane imwe nzvimbo inonzi ibvi rechimiro chechimiro.Panguva ino chiyero chesimba rinobuda re fan (Volume flow (m3/s) x Static Pressure development (Pa) nemagetsi ekuisa simba remagetsi (W) iri pakukura kwayo uye kudzvinyirirwa kuri kugadzirwa nefani kuchave. Pakunyarara kwacho.Pamusoro nepasi pezvakanyanya siyana yekushanda kuyerera nemufanhi kunowedzera ruzha uye kushanda zvakanaka kwefan system kunodzikira.
Kubatsira kwekushandisa imwe inlet kumberi yakakomberedzwa mota impeller ndeyekuti ine yakakwira fan hunhu.Izvi zvinonyanya kukosha mumasisitimu anoda kuenderana mazinga ekusefa.Mhepo painopfuura nepasefa sefa sefa inosunga huruva nemukume, zvinoita kuti giredhi rekusefa rive diki diki twudiki twasungwa nesefa.Nekufamba kwenguva iyo sefa ichawedzera kuvharwa netsvina nemarara izvo zvine mhedzisiro yekuti kudzvanywa kwakawanda kunodiwa kuendesa huwandu hwemhepo hwakafanana.Kushandisa impeller ine inokwira hunhu curve mune iyi kesi zvinoreva kuti sezvo sefa inowedzera kuvharika, kuyerera kwevhoriyamu kunoramba kuripo apo kudzvanywa kwesefa kuri kuwedzera.
Kubatsira kwekushandisa kaviri inlet kumberi kwakakomberedzwa impeller ndeyekuti kubva kune idiki saizi blower inogona kuburitsa yakakwira-vhoriyamu kuyerera.Iko kuwirirana nekushandisa kaviri inlet blower ndeyekuti ine yakaderera kusimudzira kusimudzira zvichireva kuti inogona chete kushanda neakaderera masisitimu ekumanikidza.
Mounting sarudzo
Sezvambotaurwa, iyo yekumberi yakakomberedzwa yemota impeller inoburitsa yakakwira velocity mweya pamazano eblade inoda kutungamirwa uye kunonokerwa kushandura kudzvanywa kwesimba kuita static pressure.Kufambisa izvi, tinovaka mupumburu wakatenderedza impeller.Chimiro chinogadzirwa nereshiyo yezvinhambwe kubva pakati peimpeller kusvika kune fan outlet.Sezvineiwo neyekumashure curved fan inokurudzirwa zvakare kuve nediki kupindirana pakati peinopinza mhete uye muromo we impeller.Mafungiro ese ari maviri anoratidzwa mudhayagiramu pazasi…
Iyo inlet mhete dhayamita inofanirwa kungobvumidza kamukana kadiki pakati peimpeller nemhete kudzivirira kutenderera kwemhepo.
Kuwedzera kufunga - Clearances
Izvo zvakakosha kuve nechokwadi chakakwana clearance pane kusveta uye parutivi rwe fan…
Kusakwana kubvumidzwa padivi rekusveta re fan kuchawedzera inlet velocity izvo zvinozotungamira kune mhirizhonga.Iyi mhirizhonga ichawedzerwa sezvo mhepo inopfuura nepamhepo inoita kuti kuendeswa kwesimba kubva kune fan blade kuenda kumhepo kusanyanya kushanda, kunokonzera kusikwa kwemheremhere uye kuderedza kushanda kwefani.

Pfupiso - Sei Kusarudza kumberi kwakakomberedzwa centrifugal fan?
Kana iyo inodiwa poindi yebasa inowira munzvimbo yekumusoro masisitimu madhindindi zvichienderana nekushomeka kwevhoriyamu kuyerera pane fan hunhu imwe inopinza yekumberi yakakomberedzwa centrifugal fan inofanirwa kutariswa.Kana chinodiwa chekushandisa chiri chepamusoro-vhoriyamu kuyerera mune yakaganhurirwa nzvimbo hamvuropu inopinza kaviri kumberi kwakakomberedzwa centrifugal fan inofanirwa kutariswa.
Iyo feni inofanirwa kusarudzwa mukati meiyo optimum range iri pane inozivikanwa seibvi rehunhu hwayo curve.Iyo poindi yekushanda kwepamusoro iri padhuze nepamusoro-kudzvanywa muganho pane fan hunhu curve iyo iri kushandawo pakunyarara kwayo.Kushanda kunze kweiyo optimum range (pakunyanyisa kwekuyerera kwevhoriyamu) kunofanirwa kudziviswa sezvo mhirizhonga uye kugona kweaerodynamic kweiyo impeller blade panzvimbo idzi kuchagadzira ruzha uye impeller ichave ichishanda mune aerodynamic stall.Pakumanikidzwa kwakaderera uye kuyerera kwepamusoro-kuyerera kunofanirwa kupihwa kune tembiricha yekushanda yemota iri pasi pemutoro sezvo paine mukana wekuti mota yakawandisa iitike.
Mhepo padivi rekupinza reimpeller inofanira kuchengetedzwa seyakatsetseka uye laminar sezvinobvira.Kuti uwedzere kushanda zvakanaka, kubvumidzwa kwe 1/3rd ye impeller dhayamita kunofanirwa kubvumidzwa pane fan inlet.Kushandisa mhete yekupinda (Inlet nozzle) inoputira iyo impeller inlet ichabatsira kubvisa kuvhiringika kwekuyerera mweya usati wadhonzwa kuburikidza nefeni, kuderedza mhirizhonga inokonzeresa ruzha, chengetedza mashandisiro emagetsi panzvimbo yebasa kusvika kushoma uye nekuwedzera kushanda nesimba.
Hunhu hwekukwirisa hwekushanda, kugona kwepamusoro-kudzvanya kweanofuridza imwe inlet uye kuyerera kwepamusoro kwekaviri inlet blowers zvinoreva kuti iyo yekumberi yakakomberedzwa feni isarudzo inobatsira yekufunga nezve kwakasiyana siyana yekuisa.
