Uyini Umehluko Phakathi Kwabalandeli Nama-Blowers?

i-rth (1)

Amasistimu e-HVAC athembele kumshini wokungenisa umoya wokushisisa isikhala nomoya, njengoba ama-chiller namabhayela ngokwawo awakwazi ukuletha umphumela wokushisisa noma wokupholisa lapho kudingekile.Ngaphezu kwalokho, izinhlelo zokungenisa umoya ziqinisekisa ukutholakala komoya ohlanzekile njalo ezindaweni zasendlini.Ngokusekelwe kungcindezi kanye nezidingo zokugeleza komoya zohlelo ngalunye, kusetshenziswa ifeni noma i-blower.

Ngaphambi kokuxoxa ngezinhlobo eziyinhloko zabalandeli nabafutha, kubalulekile ukuqonda umehluko phakathi kwemiqondo yomibili.I-American Society of Mechanical Engineers (ASME) ichaza abalandeli nezifutha ngokususelwe esilinganisweni esiphakathi kokucindezela kokukhipha kanye nokucindezela kokumunca.

  • Umlandeli:Isilinganiso sengcindezi sifika ku-1.11
  • Isiqhumiso:Isilinganiso sengcindezi sisuka ku-1.11 siye ku-1.2
  • I-Compressor:Isilinganiso sokucindezela sidlula u-1.2

Amafeni nama-blower ayadingeka ukuze umoya unqobe ukumelana nokugeleza okubangelwa izingxenye ezinjengamapayipi nama-dampers.Kunezinhlobo eziningi ezitholakalayo, ngayinye ilungele izinhlelo ezithile.Ukukhetha uhlobo olulungile kusiza ukuthuthukisa ukusebenza kwe-HVAC, kuyilapho ukukhetha okungalungile kuholela ekumoshweni kwamandla.


Ingabe usebenzisa imishini eyanele yokukhipha umoya?

Izinhlobo Zabalandeli

Amafeni angahlukaniswa abe yi-centrifugal noma i-axial ngokusekelwe endleleni abasungula ngayo ukugeleza komoya.Ngokulandelayo, kunezinhlobo ezimbalwa ezingaphansi esigabeni ngasinye, futhi ukukhetha ifeni efana nohlelo lokusebenza kubalulekile ekufakweni kokusebenza okuphezulu kwe-HVAC.

Ithebula elilandelayo lifingqa izinhlobo eziyinhloko zabalandeli be-centrifugal: i-radial, i-curved phambili, ijika eligobile kanye nohlobo lwe-airfoil.

UHLOBO LWEFAN DESCRIPTION
I-Radial -Ukucindezela okuphezulu nokugeleza okuphakathi
-Ibekezelela uthuli, umswakama nokushisa, ikwenze ifanele ukusetshenziswa kwezimboni
-Ukusetshenziswa kwamandla kukhuphuka kakhulu kanye nokugeleza komoya
Phambili ijika -Ingcindezi emaphakathi nokugeleza okuphezulu
-Ifanele amasistimu e-HVAC anengcindezi ephansi ngokuqhathaniswa, njengamayunithi ophahleni olupakishiwe
-Ibekezelela uthuli, kepha ayilungele izilungiselelo zezimboni ezinokhahlo
-Ukusetshenziswa kwamandla kukhuphuka kakhulu kanye nokugeleza komoya
Igobile emuva -Ukucindezela okuphezulu nokugeleza okuphezulu
-Amandla ayonga
-Ayizwa ukwanda okukhulu kwengcindezi ngokugeleza komoya
-HVAC kanye nezicelo zezimboni, nazo zaphoqelela izinhlelo zokusalungiswa
I-airfoil -Ukucindezela okuphezulu nokugeleza okuphezulu
-Amandla ayonga
-Yakhelwe izinhlelo zokusebenza ezinomoya ohlanzekile

Ngakolunye uhlangothi, abalandeli be-axial flow bahlukaniswa ngama-propeller, i-tube axial kanye ne-vane axial.

UHLOBO LWEFAN DESCRIPTION
Uphephela -Ukucindezela okuphansi nokugeleza okuphezulu, ukusebenza kahle okuphansi
-Ifanele amazinga okushisa aphakathi nendawo
-Ukugeleza komoya kuncipha kakhulu uma umfutho we-static ukhuphuka.
-Izinhlelo zokusebenza ezijwayelekile zifaka abalandeli be-exhaust, ama-condenser angaphandle nemibhoshongo yokupholisa
I-axial ye-tube -Ingcindezi emaphakathi nokugeleza okuphezulu
-Izindlu ezingama-cylindrical kanye nemvume encane enama-fan blades ukuthuthukisa ukugeleza komoya
-Isetshenziswa ku-HVAC, izinhlelo zokuqeda amandla kanye nezinhlelo zokumisa
Vane axial -Ukucindezela okuphezulu nokugeleza okuphakathi, ukusebenza kahle okuphezulu
-Ngokufana ngokomzimba namafeni we-axial we-tube, ukuhlanganisa ama-vanes omhlahlandlela ekuthathweni ukuze kuthuthukiswe ukusebenza kahle
-Ukusetshenziswa okuvamile kufaka phakathi i-HVAC kanye nezinhlelo zokukhipha umoya, ikakhulukazi lapho kudingeka khona ukucindezela okukhulu

Ngokhetho olubanzi kangaka lwabalandeli, kunesixazululo cishe sanoma yiluphi uhlelo lokusebenza.Kodwa-ke, ukuhlukahluka kusho ukuthi maningi amathuba okukhetha ifeni engalungile ngaphandle kokuqondiswa okufanele.Isincomo esingcono kakhulu ukugwema izinqumo "zokubusa kwesithupha", futhi esikhundleni salokho uthole umklamo wochwepheshe ohlangabezana nezidingo zephrojekthi yakho.

Izinhlobo Zokushaywa

Njengoba kushiwo ngaphambili, ama-blower asebenza nge-pressure ratio engu-1.11 kuya ku-1.2, okuwenza abe maphakathi phakathi kwefeni ne-compressor.Zingakhiqiza izingcindezi eziphakeme kakhulu kunabalandeli, futhi ziyasebenza nasekufakweni kwe-vacuum yezimboni ezidinga ukucindezela okungekuhle.Ama-blower ahlukaniswe ngezigaba ezimbili eziyinhloko: i-centrifugal kanye ne-positive displacement.

Ama-centrifugal blowersabe nokufana okuthile ngokomzimba namaphampu amaphakathi.Ngokuvamile zihlanganisa isistimu yegiya ukuze uthole isivinini esingaphezu kuka-10,000 rpm.Ama-centrifugal blower angaba nesiteji esisodwa noma ukwakhiwa kwezigaba eziningi, lapho umklamo wesiteji esisodwa unikeza ukusebenza kahle okuphezulu, kodwa umklamo wezigaba eziningi unikeza ububanzi obubanzi bokugeleza komoya ngokucindezela okuqinile.

Njengabalandeli, ama-centrifugal blower anezinhlelo zokusebenza ku-HVAC.Kodwa-ke, ngenxa yokukhishwa kwengcindezi ephakeme kakhulu, asetshenziselwa ukuhlanza imishini kanye nezinhlelo zokusebenza zezimoto.Umkhawulo wabo omkhulu ukuthi ukugeleza komoya kuncipha ngokushesha lapho isithiyo siphakamisa ingcindezi, okubenza bangafaneleki izinhlelo zokusebenza ezinethuba elikhulu lokuvala.

Ama-blower okuhambisa kahleube ne-rotor geometry eklanyelwe ukubamba amaphakethe omoya, ukushayela ukugeleza endaweni ehlosiwe ekucindezelweni okuphezulu.Nakuba ezungeza ngesivinini esiphansi kunama-centrifugal blower, angakhiqiza umfutho owanele wokuphephula izinto ezivala uhlelo.Omunye umehluko obalulekile ngezinketho ze-centrifugal ukuthi ama-positive-displacement blower ngokuvamile ashayelwa amabhande esikhundleni samagiya.

Isiphetho

Amafeni namafutha ngokuvamile acaciswa ngokusekelwe kungcindezi kanye nezimfuneko zokugeleza komoya zohlelo ngalunye, kanye nezimo eziqondene nesayithi njengothuli nezinga lokushisa.Uma uhlobo olulungile lwefeni noma isiphephetha-moya sesicacisiwe, ukusebenza ngokuvamile kungathuthukiswa ngamasistimu okulawula.Ngokwesibonelo,ama-variable frequency drives (VFD)kunganciphisa kakhulu ukusetshenziswa kukagesi kwabalandeli abasebenza ngezikhathi ezithile.
