Nigute ushobora guhitamo umufana ukwiye

1 、 Nigute ushobora guhitamo umufana winganda?

Abakunzi binganda barashobora gukoreshwa mubikorwa byinshi kandi bafite ibishushanyo bitandukanye:

-Umufana wuzuye

-Kuramo umufana

-Umufana mwiza

-Umufana w'abaminisitiri

-Abandi.

Intambwe yambere nukumenya ubwoko bwabafana basabwa.

Guhitamo ikoranabuhanga mubusanzwe bikorwa hagati ya axial flow fan na centrifugal fan. Muri make, abafana ba axial barashobora gutanga umwuka mwinshi hamwe nubushyuhe bukabije, kubwibyo bikwiranye gusa nigabanuka ryumuvuduko muke (mugihe gito cyumuzunguruko), mugihe abafana ba centrifugal bakwiriye cyane kugabanuka kwumuvuduko mwinshi (umuzunguruko muremure). Abafana ba Axial flow nabo muri rusange barushijeho guhuzagurika no gusakuza kuruta abafana ba centrifugal.

Abafana batoranijwe kugirango batange urugero runaka rwumwuka (cyangwa gaze) kurwego runaka. Kubisabwa byinshi, guhitamo biroroshye kandi igipimo cyurugendo rwerekanwe nuwabikoze kirahagije kubara ingano yabafana. Ibintu birushaho kuba ingorabahizi mugihe umufana ahujwe numuzunguruko (umuyoboro uhumeka, gutanga umwuka kuri firime, nibindi). Umwuka utangwa nabafana biterwa nibiranga kandi nanone biterwa nigabanuka ryumuvuduko wumuzunguruko. Iri ni ihame ryumwanya wakazi: niba umurongo wumuvuduko wumuvuduko wumurongo wumurongo wikigereranyo cyumuvuduko wigihombo, umurongo wakazi wumufana murumuzunguruko uzaba uri kumasangano yimirongo ibiri.

Nubwo abafana benshi bakorera mubushyuhe bwicyumba, abafana bamwe bagomba gukora kubushyuhe bwihariye cyangwa ibidukikije. Nibibaho, kurugero, hamwe nabafana bazenguruka mu ziko. Kubwibyo, ni ngombwa guhitamo ubwoko butandukanye bwabafana ukurikije porogaramu zitandukanye.

2 、 Kuki uhitamo umuyaga ukabije?

Umuyaga uzunguruka (cyangwa umuyaga utemba wa axial) ugizwe na moteri ifite moteri izunguruka ku murongo. Icyuma gisunika umwuka utembera ugereranije nu murongo wo kuzunguruka.

Umuyaga uzunguruka urashobora gutanga umwuka mwinshi, ariko umuvuduko uri hagati yimbere no hepfo ntiwiyongereye. Kuberako umuvuduko ukabije uri muke cyane, imikoreshereze yabo igarukira kumuzingo mugufi uterwa no kugabanuka k'umuvuduko muke.

Abafana ba Axial mubusanzwe bafite ibyuma 2 kugeza kuri 60. Imikorere yayo ni 40% kugeza 90%.

Uyu mufana muri rusange akoreshwa mu kuzenguruka ikirere mu byumba binini, binyuze mu guhumeka urukuta no guhumeka imyanda mu byumba.

Ugereranije nabafana ba centrifugal, umuyaga uzenguruka ufata umwanya muto, ugura make kandi ufite urusaku ruke.

3 、 Kuki uhitamo umufana wa centrifugal?

Umufana wa centrifugal (cyangwa umuyaga utemba) ugizwe nuruziga rwumufana (impeller), rutwarwa na moteri izunguruka muri stator ihujwe nuwimuka. Stator ifite ibyerekezo bibiri: gufungura kwambere bitanga amazi mugice cyo hagati cyuwimura, amazi yinjira mu cyuho, naho icya kabiri gifungura ku nkombe binyuze mubikorwa bya centrifugal.

Hariho ubwoko bubiri bwabafana ba centrifugal: umufana wimbere wimbere hamwe numufana winyuma. Umufana wimbere ugororotse wa centrifugal ufite "akazu ka squirrel" hamwe na 32 kugeza 42. Imikorere yayo ni 60% kugeza 75%. Imikorere yumukunzi wa centrifugal isubira inyuma ni 75% kugeza 85%, naho ibyuma ni 6 kugeza 16.

Umuvuduko ukabije uruta uw'umufana wa spiral, bityo umuyaga wa centrifugal ukwiranye nigihe kirekire.

Abafana ba Centrifugal nabo bafite akarusho mubijyanye nurusaku: baracecetse. Ariko, ifata umwanya munini kandi igatwara ibirenze inkubi y'umuyaga.

4 、 Nigute ushobora guhitamo umufana wa elegitoroniki?

Abafana ba elegitoroniki ni buke kandi bafunze abafana bafite ibipimo bisanzwe hamwe na voltage yo gutanga (AC cyangwa DC) kugirango byoroshye kwishyira hamwe.

Umufana ukoreshwa mugukuraho ubushyuhe butangwa nibikoresho bya elegitoronike murugo. Hitamo ukurikije ibihe bikurikira:

Kwimura ikirere

ingano

Tanga voltage iboneka murugo

Kugirango ubashe guhuzagurika, abafana benshi ba elegitoronike ni abafana bazenguruka, ariko hariho nabafana ba centrifugal na diagonal, bashobora gutanga umwuka mwinshi.

5 、 Nigute ushobora guhitamo abafana kumashanyarazi?

Umuyaga w'amashanyarazi urashobora guhumeka umwuka ukonje muri guverenema kugirango ugabanye ubushyuhe bwibikoresho bya elegitoroniki. Barinda umukungugu kwinjira muri guverenema mukurema igitutu gito.

Mubisanzwe, aba bafana bashyizwe kumuryango cyangwa kurukuta rwinama yinama y'abaminisitiri kandi byinjijwe mumurongo uhumeka. Hariho na moderi zimwe zishobora gushyirwaho hejuru yinama y'abaminisitiri. Bafite ibikoresho byo kuyungurura kugirango birinde umukungugu kwinjira muri guverinoma.

Guhitamo uyu mufana bishingiye kuri:

Kwimura ikirere

Inama y'abaminisitiri itanga ingufu

Imikorere ya filteri
