1. Yadda za a zabi masana'antu fan?
Ana iya amfani da magoya bayan masana'antu don dalilai da yawa kuma suna da tsari iri-iri:
-Mai haɗe-haɗe
- Mai fanko
-Mai motsi
-Mai son wutar lantarki
-Sauran.
Mataki na farko shine ƙayyade nau'in fan da ake buƙata.
Yawancin zaɓin fasaha ana yin su ne tsakanin fanin axial flow fan da centrifugal fan.A takaice dai, magoya bayan axial na iya samar da iska mai zurfi da ƙananan matsa lamba, don haka sun dace kawai don aikace-aikacen ƙananan matsa lamba (gajeren kewayawa), yayin da magoya bayan centrifugal sun fi dacewa da aikace-aikacen matsa lamba mai tsayi (tsawon lokaci).Masoyan kwararan axial suma gabaɗaya sun fi ƙanƙanta da hayaniya fiye da daidaitattun magoya bayan tsakiya.
An zaɓi magoya baya don samar da wani adadin iska (ko gas) a wani matakin matsa lamba.Don aikace-aikace da yawa, zaɓin yana da ɗan sauƙi kuma ƙimar kwararar da mai ƙira ya nuna ya isa don ƙididdige girman fan.Halin ya zama mafi rikitarwa lokacin da aka haɗa fan ɗin zuwa kewaye (cibiyar sadarwar iska, samar da iska zuwa mai ƙonawa, da dai sauransu).Gudun iskar da fan ɗin ke bayarwa ya dogara da halayensa kuma ya dogara da digon da'ira.Wannan shine ka'idar wurin aiki: idan an zana madaidaicin madaidaicin fan da madaidaicin madaidaicin matsi, wurin aiki na fan a cikin wannan da'irar zai kasance a tsakiyar mahadar biyun.
Ko da yake yawancin magoya baya suna aiki a cikin zafin jiki, wasu magoya baya dole ne suyi aiki a takamaiman yanayin zafi ko yanayin muhalli.Wannan shi ne yanayin, alal misali, tare da fan mai kewayawa a cikin tanda.Saboda haka, yana da mahimmanci don zaɓar nau'ikan fan daban-daban bisa ga aikace-aikace daban-daban.
2. Me ya sa za a zabi karkace fan?
Mai karkace fan (ko fanfo mai gudana axial) ya ƙunshi farfela wanda injinsa ke jujjuya kan axis.Fure-fure yana tura iskar ta daidai da kusurwar juyi.
Mai jujjuyawar fan na iya samar da iskar iska mai girma, amma da kyar matsa lamba tsakanin sama da kasa ya karu.Saboda yawan matsa lamba yana da ƙasa sosai, amfani da su yana iyakance ga gajeriyar kewayawa da ke haifar da raguwar matsa lamba.
Magoya bayan axial yawanci suna da ruwan wukake 2 zuwa 60.Ingancin sa shine 40% zuwa 90%.
Ana amfani da wannan fanka gabaɗaya don zazzagewar iska a cikin manyan ɗakuna, ta hanyar iskar bango da iskar bututu a ɗakuna.
Idan aka kwatanta da fan na centrifugal, fan ɗin karkace ya mamaye ƙasa kaɗan, farashi mai ƙarancin ƙima kuma yana da ƙaramar hayaniya.
3. Me yasa zabar centrifugal fan?
Mai fan na centrifugal (ko fan na runoff) ya ƙunshi motar fan (impeller), wanda injin ke motsa shi wanda ke jujjuyawa a cikin stator ɗin da aka haɗa da impeller.Stator yana da buɗewa guda biyu: buɗewa ta farko tana ba da ruwa zuwa tsakiyar ɓangaren impeller, ruwan yana ratsawa ta hanyar injin, buɗaɗɗen buɗewa na biyu yana busawa zuwa gefen ta hanyar aikin centrifugal.
Akwai nau'ikan magoya bayan centrifugal iri biyu: fann lanƙwasa gaba da lanƙwasawa fan.Mai lankwasa centrifugal fan na gaba yana da " kejin squirrel" mai motsa jiki da ruwan wukake 32 zuwa 42.Ingancin sa shine 60% zuwa 75%.Ingancin fan na centrifugal mai lankwasa baya shine 75% zuwa 85%, kuma adadin ruwan wukake shine 6 zuwa 16.
Matsakaicin matsi ya fi na fanƙar karkace, don haka fanin centrifugal ya fi dacewa da dogon kewayawa.
Magoya bayan Centrifugal kuma suna da fa'ida dangane da matakan amo: sun fi shuru.Koyaya, yana ɗaukar ƙarin sarari kuma yana kashe kuɗi fiye da karkace guguwar.
4. Yadda ake zabar fan na lantarki?
Magoya bayan na'urorin lantarki masu ƙanƙanta ne kuma magoya bayan rufewa tare da ma'auni na ma'auni da samar da wutar lantarki (AC ko DC) don haɗawa cikin sauƙi a cikin shinge.
Ana amfani da fan don kawar da zafin da kayan lantarki ke haifarwa a cikin yadi.Zaɓi bisa ga sharuɗɗa masu zuwa:
Matsar da iska
girma
Ana samun wutar lantarki a cikin yadi
Don kare kanka, yawancin magoya bayan lantarki sune magoya bayan karkace, amma akwai kuma masu gudana na centrifugal da diagonal, wanda zai iya samar da mafi yawan iska.
5. Yadda za a zabi fan ga lantarki hukuma?
Mai fan na majalisar lantarki zai iya hura iska mai sanyi a cikin majalisar don daidaita zafin kayan aikin lantarki.Suna hana ƙura shiga majalisar ministocin ta hanyar haifar da danniya.
Gabaɗaya, ana shigar da waɗannan magoya baya akan ƙofar ko bangon gefen majalisar kuma an haɗa su cikin hanyar sadarwar samun iska.Har ila yau, akwai wasu samfura waɗanda za a iya sanya su a saman majalisar.An sa musu kayan tacewa don hana ƙura daga shiga majalisar.
Zaɓin wannan fan ya dogara ne akan:
Matsar da iska
