Uburyo bwo gukoresha DC Brushless Blower: Ubuyobozi bwuzuye

Utwuma dukoresha uburoso bwa DC ni ingenzi mu bikorwa byinshi bigezweho, kuva ku bikoresho by'ubuvuzi n'uturemangingo twa lisansi kugeza ku buryo bwo gukonjesha no gusukura umwuka mu nganda. Tuzwiho imikorere myiza, ingano nto, no kugenzura umuvuduko neza, utu dukoso dukenera gushyirwaho no gufatwa neza kugira ngo dukore neza kandi mu buryo bwizewe. Iyi nkuru itanga ubuyobozi burambuye bw'intambwe ku yindi ku buryo bwo gushyiraho, gukoresha, no gukemura ikibazo cy'uburyo bwo gukoresha uburoso bwa DC bushingiye ku gitabo cy'amabwiriza asanzwe y'ibicuruzwa.

1. Sobanukirwa n'ibice bigize sisitemu

Mbere yo gukoresha DC brushless blower, ni ngombwa gusobanukirwa ibice by'ingenzi bya sisitemu:

Isoko y'amashanyarazi ya DC: Itanga ingufu za DC zifite voltage nkeya ku cyuma gitanga umwuka.
Insinga z'amashanyarazi: Itwara umuriro uva ku isoko ujya ku mugenzuzi.
Umugenzuzi: Icunga umuvuduko n'imikorere y'icyuma gitanga umwuka.
Imashini ikoresha amafuru: Imashini ikoresha moteri itwara umwuka.
Potentiometer: Akabuto gakoresha intoki gatuma abakoresha bashobora kugenzura umuvuduko w'icyuma gisohora umwuka.

Buri gice muri ibi bigomba kuba bihujwe neza kandi bigashyirwamo mbere yuko sisitemu itangira gukoreshwa.

2. Amabwiriza y'umutekano

Umutekano ugomba kuza ku mwanya wa mbere mu gihe ukoresha ibikoresho by'amashanyarazi n'imashini. Kurikiza aya mabwiriza y'umutekano kugira ngo wirinde kwangirika cyangwa gukomereka:

Irinde ko habaho aho umwuka winjiriramu gihe cyo kubagwa kugira ngo hirindwe imvune.
Shyira nezaicyuma gitera umwuka mbere yo gutangira gukumira kugenda cyangwa guhindagura.
Menya neza ko icyuma gitera umwuka kidakoraguhumeka amazi, umwuka wangiza, cyangwa ibinyobwa, bishobora kwangiza ibice by'imbere.
Koresha icyuma gitanga umwuka mu bidukikije bifite ubushyuhe buri hagati ya-20°C na 60°CKuyikoresha hanze y'uru rwego bishobora gutera imikorere mibi.

3. Guhuza no Gutanga Ingufu ku Kimashini Gifumura

Insinga zikwiye ni ingenzi cyane kugira ngo imikorere ikore neza kandi mu mutekano:

Huzainsinga itukuraku gice cy'ingufu (+) cyiza (positive) n'aho isoko y'amashanyarazi ikorera ndetseinsinga y'umukarakuri terminal iri hasi (-).
Menya neza ko voltage y'amashanyaraziihuye n'imbaraga z'amashanyarazi zikoreshwa n'icyuma gisohora umwuka, kandi umusaruro uriho ubu nihejuru y'umuvuduko ntarengwa w'amashanyarazi ukoreshwa n'icyuma gisohora umwuka.

Iyo insinga zirangiye, banza urebe neza niba zimeze neza kandi zifite umutekano mbere yo gukoresha igikoresho.

4. Kugenzura Umuvuduko w'Imashini Ikoresha Umwotsi

Utwuma dukoresha uburoso bwa DC dutanga uburyo bwinshi bwo kugenzura umuvuduko, bigatuma dushobora gukoreshwa mu buryo butandukanye.

a. Igenzura rya Potentiometer

Niba sisitemu irimo potentiometer:

Guhindura agapfundoukurikije icyerekezo cy'isahanzatangiza icyuma gitera umwuka.
Umuvuduko uzakomeza kwiyongera buhoro buhoro uko agapfundo kazagenda gakomeza guhindurwa.

Ubu buryo bworoshye gukoresha kandi bukwiriye ahantu ho gukosora hakoreshejwe intoki.

b. Igenzura ry'ingufu za analoji (0–5V)

Niba hakenewe uburyo bwo kugenzura ikoranabuhanga bunoze:

Kuraho potentiometer.
ShyirahoIkimenyetso cya DC cya 0–5Vhagati yainsinga yo kugenzura imvin'insinga y'umukara yo hasi.
Kongera voltage kuva kuri 0V kugeza kuri 5V bizongera umuvuduko w'imashini isohora umwuka mu buryo bungana.

Ubu buryo ni bwiza kuri sisitemu zigomba guhindura umuvuduko w'icyuma gisohora amashanyarazi mu buryo bwikora hashingiwe ku byuma bipima cyangwa ibindi bikoresho bigenzura.

c. Igenzura rya PWM

Ku bijyanye na sisitemu zigezweho za digitale:

Kuraho potentiometer.
ShyirahoPWM (Ubugari bw'ingufu)ikimenyetso hagati yainsinga y'imvin'insinga y'umukara.
Ikimenyetso kigomba kugira amplitude ya5Vn'inshuro hagati ya2kHz na 50kHz.

PWM ni uburyo bukoreshwa cyane muri sisitemu zo kugenzura zishyirwamo bitewe n'uburyo bworoshye bwo guhindura imikorere no gukoresha neza ingufu.

5. Ibindi Biranga Imikorere

Utwuma dukoresha uburoso bwa DC akenshi tuza dufite imikorere myiza yubatswemo:

Fungura/Hagarika Imikorere:
Guhuzainsinga y'umuhengerikuriinsinga y'umukaraBihagarika icyuma gitera umwuka. Kuzikuraho bituma zikora. Ibi ni ingirakamaro mu gukoresha uburyo bwo kuzimya/kuzimya bwa kure.
Gusubira inyuma mu cyerekezo:
Guhuzainsinga y'icyatsi kibisikuriinsinga y'umukaraizahindura icyerekezo cyo kuzenguruka kwa moteri. (Icyitonderwa: Ibi bireba moteri gusa, ntabwo bireba ibikoresho bitanga umwuka aho icyerekezo cy'umwuka gihamye.)
Igisubizo cy'umuvuduko (Ikimenyetso cya FG):
Itsindainsinga y'umweruitanga uburyo bwo kugenzura umuvuduko w'amaraso.
- KuriIcyitegererezo cya WS7040, buri Hz ihuye na 60 RPM.
- Kuriizindi moderi, 1 Hz = 30 RPM.
Uburinzi bw'ubushyuhe bukabije:
Hari ibyuma bitanga umwuka bishyigikira icyuma gikingira ubushyuhe kizimya moteri mu buryo bwikora iyo ubushyuhe bw'imbere buzamutse hejuru y'umurongo utekanye.

6. Gufata no Kubika

Kwita no kubika neza ni ingenzi kugira ngo icyuma gikoresha umwuka gikomeze gukora neza no kongera igihe cyacyo cyo kubaho:

Bika ahantu humutsekugira ngo hirindwe ingese imbere.
Ntugasenye impeller, kuko bishobora gutera ubusumbane n'urusaku.
Menya neza ko impeller ikorera muriukurikije isaha inyuranyije n'isaha (CCW)icyerekezo, ari na cyo cyerekezo gikwiye cyo gukora.

7. Gukemura ibibazo hakoreshejwe amakode y'amakosa ya LED

Iyo icyuma gitanga umwuka kidakora neza, ibimenyetso bya LED byubatswemo bishobora gufasha kumenya ikibazo:

Amatara yombi ya LED ari ku: Moteri cyangwa umushoferi yashyushye cyane.
Imiterere y'urumuri rwa LED2 buhoro buhoro:
- Inshuro 2: Kudakoresha ingufu nyinshi cyangwa kurenga ingufu z'amashanyarazi.
- Inshuro 3: Ikosa ryo gupima ubu cyangwa ikibazo cy'insinga.
- Inshuro 4: Moteri yafatiriwe.
- Inshuro 5: Kunanirwa kw'icyiciro.
- Inshuro 6: Ikosa rya sensor ya Hall.
Imiterere y'urumuri rwihuse rwa LED2:
- Inshuro 1–4: Ibibazo by'uruziga rw'imodoka cyangwa imiyoboro migufi.
LED2 irazimye: Moteri ikora neza.
Umucyo upima LED2: Moteri yahagaze nk'uko bisanzwe (nta muvuduko winjizwa).
Umucyo wihuse wa LED2 inshuro 4: Uburinzi bw'amashanyarazi arenze urugero burakora.

Reba igitabo cy'amabwiriza cyangwa uwakoze porogaramu kugira ngo ubone ibindi bisobanuro niba bikenewe.

Umwanzuro

Gukoresha DC brushless blower biroroshye iyo umaze gusobanukirwa ibice byayo n'imikorere yayo. Waba urimo guhindura umuvuduko ukoresheje potentiometer, voltage ya analog, cyangwa ikimenyetso cya PWM, izi blower zitanga imikorere yoroshye, ituje kandi yizewe. Buri gihe kurikiza amabwiriza y'umutekano n'amabwiriza y'insinga, kandi ukoreshe ibimenyetso byubatswemo by'ibitekerezo n'amakosa kugira ngo ukurikirane uko sisitemu ihagaze.

Iyo ikoreshejwe neza kandi ikora neza, icyuma cyawe gitanga umwuka kizatanga umusaruro uhoraho mu buryo ubwo aribwo bwose—byaba ari ugukoresha icyuma gifasha guhumeka mu buvuzi, gishyigikira ingirabuzimafatizo za hydrogen, cyangwa ibikoresho by'ikoranabuhanga bikonjesha.
