Mashandisiro Ekushandisa DC Brushless Blower: Gwaro Rakakwana

Mabhurashi eDC asina mabhurashi zvinhu zvakakosha mukushandiswa kwakawanda kwemazuva ano, kubva pamidziyo yekurapa uye mafekitori emafuta kusvika kumasisitimu ekutonhodza uye ekuchenesa mweya mumaindasitiri. Anozivikanwa nekushanda kwawo kwepamusoro, saizi shoma, uye kudzora kumhanya kwakaringana, mabhurashi aya anoda kugadziriswa kwakakodzera uye kubatwa zvakanaka kuti ave nechokwadi chekuti mashandiro akachengeteka uye akavimbika. Chinyorwa chino chinopa gwara rakadzama rekuti ungaisa sei, kushandisa, uye kugadzirisa dambudziko nemazvo sei sisitimu yeDC isina mabhurashi zvichibva pabhuku remirayiridzo yechigadzirwa.

1. Nzwisisa Zvikamu zveSisitimu

Usati washandisa DC brushless blower, zvakakosha kunzwisisa zvikamu zvikuru zvesystem iyi:

Simba reDC: Inopa simba reDC rine simba shoma kumuchina unoburitsa mhepo.
Waya yemagetsi: Inotakura simba kubva kunobva magetsi kuenda kucontroller.
Mutongi: Inotarisira kumhanya uye mashandiro emuchina wekufemesa.
Mudziyo wekuvhuvhuta: Chipenga chinofambiswa nemota chinofambisa mhepo.
Potentiometer: Chinongedzo chemaoko chinobvumira vashandisi kudzora kumhanya kwemuchina wekuputira.

Chimwe nechimwe chezvinhu izvi chinofanira kunge chakabatana zvakanaka uye chakaiswa system isati yabatidzwa.

2. Nhungamiro dzekuchengetedza

Kuchengetedzeka kunofanira kugara kuri pekutanga pakushanda nemidziyo yemagetsi neyemakanika. Tevedzera mirairo iyi yekuchengetedza kudzivirira kukuvara kana kukuvara:

Dzivisa kusangana nemhepo inopinzwapanguva yekuvhiyiwa kudzivirira kukuvara.
Isa zvakachengetekamuchina wekufemesa usati watanga kudzivirira kufamba kana kudedera.
Iva nechokwadi chekuti muchina wekufemera hauitifema mvura, gasi rinoparadza, kana zvinwiwa, izvo zvinogona kukuvadza zvikamu zvemukati.
Shandisa chiputiriso munzvimbo dzine tembiricha iri pakati-20°C uye 60°CKushandisa kunze kwenzvimbo iyi kunogona kukonzera kusashanda zvakanaka.

3. Kubatanidza nekushandisa Power muBlower

Kubatanidza waya kwakakodzera kwakakosha pakushanda kwakachengeteka uye zvinobudirira:

Batanidzawaya tsvukukune terminal yakanaka (+) yesimba remagetsi uyewaya nhemakune terminal iri negative (-).
Ita shuwa kuti voltage yemagetsi inoyererainoenderana nemagetsi akayerwa nechinhu chinoburitsa mhepo, uye zvinobuda pari zvinoyakakwira kupfuura simba remagetsi rinopfurwa nemhepo rinobuda nemhepo.

Kana waya dzapera, tarisazve kuti dzakabatana zvakanaka here uye dzakachengeteka usati waisa simba pamudziyo.

4. Kudzora Kumhanya Kwemuchina Wekuvhuvhuta

Mabhurashi eDC asina mabhurashi anopa nzira dzakawanda dzekudzora kumhanya, zvichiita kuti akwanise kushandiswa zvakasiyana-siyana.

a. Kudzora Potentiometer

Kana sisitimu yacho iine potentiometer:

Kutenderedza bhatanikutenderera kwewachindichatanga kubhururudza.
Kumhanya kuchawedzera zvishoma nezvishoma sezvo bhatani richitenderedzwa mberi.

Nzira iyi iri nyore kushandisa uye yakakodzera kugadzirisa zvinhu nemaoko.

b. Kudzora Voltage yeAnalog (0–5V)

Kana zvichidikanwa kudzora kwemagetsi kwakanaka:

Bvisa potentiometer.
Isa aChiratidzo cheDC che0–5Vpakati pewaya yekudzora greyuyewaya nhema yepasi.
Kuwedzera voltage kubva pa0V kusvika pa5V kuchawedzera kumhanya kwemuchina wekuputira zvakaenzana.

Nzira iyi yakakodzera kune masisitimu anoda kugadzirisa kumhanya kweblower otomatiki zvichibva pamasensa kana zvimwe zvinopinda mukutonga.

c. Kudzora PWM

Kune masisitimu edhijitari epamusoro:

Bvisa potentiometer.
Isa aPWM (Kuchinja kwePulse Width)chiratidzo pakati pewaya yegreyuyewaya nhema.
Chiratidzo chinofanira kunge chine amplitude ye5Vuye kuwanda kwezviitiko pakati2kHz uye 50kHz.

PWM inzira inoshandiswa zvakanyanya mumasystem ekudzora akabatanidzwa nekuda kwekuchinjika kwayo uye kushanda kwayo nesimba.

5. Zvimwe Zvishandiso Zvinoshanda

Mabhurashi eDC anowanzo shandiswa nemabasa akangwara akavakirwa mukati:

Bvumira/Dzima Basa:
Kubatanidzawaya yepepurukuwaya nhemaKudzima bhaudhi kunomisa bhaudhi. Kubvisa bhaudhi kunoita kuti ishande. Izvi zvinobatsira pakudzora nekudzima bhaudhi remote.
Kudzokera Kunzira:
Kubatanidzawaya yegirinikuwaya nhemaichadzosera shure divi rekutenderera kwemota. (Cherechedza: Izvi zvinoshanda chete kumamota, kwete kumayuniti ekuputira mweya uko divi rekuyerera kwemhepo rakagadzika.)
Mhinduro Yekukurumidza (FG Signal):
Iyowaya chenainopa mukana wekuti pulse ibude papi kuti iongorore kumhanya kwemoyo.
- ZveWS7040 modhi, Hz imwe neimwe inoenderana ne60 RPM.
- Zvemamwe mamodheru, 1 Hz = 30 RPM.
Dziviriro yekupisa zvakanyanya:
Mamwe mabhurosi anotsigira chinodzivirira kupisa chinodzima mota otomatiki kana tembiricha yemukati ikakwira kupfuura chiyero chakachengeteka.

6. Kubata uye Kuchengeta

Kuchengetedza nekuchengetedza kwakakodzera kwakakosha pakuchengetedza mashandiro emuchina wekuputira uye kuwedzera hupenyu hwawo:

Chengeta munzvimbo yakaomakudzivirira ngura yemukati.
Usabvisa impeller, sezvo zvingakonzera kusawirirana uye ruzha.
Ita shuwa kuti impeller iri kushandacounterwatchwise (CCW)gwara, iro riri iro gwara rekushanda rakakodzera.

7. Kugadzirisa Matambudziko Nemakodhi Ekutadza e LED

Kana chinhu chinoburitsa mhepo chisiri kushanda nemazvo, zviratidzo zve LED zvakavakirwa mukati zvinogona kubatsira kuona dambudziko:

Ma LED ese ari maviri aripo: Mota kana mutyairi apisa zvakanyanya.
Mapatani e LED2 anopenya zvishoma nezvishoma:
- Kaviri: Kusashanda nesimba zvakanyanya kana kuti kukwira kwesimba zvakanyanya.
- Katatu: Chikanganiso chesampuli chiripo kana dambudziko rewaya.
- Ka4: Mota yakamira.
- Kashanu: Kukundikana kwechikamu.
- Katanhatu: Kukanganisa kwesensa yeHall.
Mapatani e LED2 anopenya nekukurumidza:
- Ka1–4: Matambudziko ekufambisa circuit kana ma short-circuit.
LED2 yakadzima: Mota inomhanya zvakanaka.
LED2 inopenya zvakaenzana: Mota yamira zvakajairika (hapana kupinda kwespeed).
LED2 inopenya nekukurumidza ka4: Dziviriro yemhepo yakawandisa inoshanda.

Tarisa bhuku rekushandisa kana mugadziri kuti uwane rumwe ruzivo kana zvichidikanwa.

Mhedziso

Kushandisa DC brushless blower kuri nyore kana wangonzwisisa zvikamu zvayo uye mashandiro ayo. Kunyangwe uri kugadzirisa kumhanya uchishandisa potentiometer, analog voltage, kana PWM signal, mablower aya anopa mashandiro anochinjika, akanyarara, uye akavimbika. Gara uchitevera nhungamiro dzekuchengetedza uye mirairo yewaya, uye shandisa zviratidzo zvemhinduro uye zvekukanganisa zvakaiswa mukati kuti utarise mamiriro esystem.

Kana ukaishandisa zvakanaka uye uchingwarira, blower yako ichaita basa rayo nguva dzose mune chero chinhu chinoshandiswa—ingava yekupa simba muchina wekufema wekurapa, inotsigira hydrogen fuel cell, kana magetsi anotonhodza.
