Isivinini Fan. ukulawula isivinini fan Triac

Empeleni, ukulawula ijubane fan bekulokhu ushintsho voltage ukuthi sisetshenziswa kudivayisi. Uma sikhuluma izinjini, idivayisi eziphawulwe ngenhla okunzima unesibopho sizibulale Windings. Uma lokhu ifrikhwensi lingashintsha kakhulu.

Kuyinto ngenxa nabalawuli abalandeli kagesi bayakwazi ukukhonza umnikazi iminyaka eminingi. Lokhu kwenzeka ngenxa yokuguga ukuncipha ezibalulekile zemishini. Ngaphezu kwalokho, kungenzeka ukunciphisa ukusetshenziswa kukagesi. Ngakwelinye ihlangothi, fan kuyinto ukugijima ethulile kakhulu ngesivinini ephakeme.

Thyristor fan

isivinini Thyristor fan (scheme kukhonjisiwe ngezansi) ingafakwa kuphela eyodwa imishini isigaba. Kusukela izici kungaba ukuhlukanisa uhlelo okunokwethenjelwa nokuvikeleka. Ngenxa kwamandla akhe isivinini fan kuvimbela okweqile izingxenye ezibucayi. I umfutho okuholela zingalawulwa by obuhlukahlukene amandla zamanje.

Inethiwekhi nge voltage ka 220 ukhonza njengelungu ugesi kudivayisi B. imvamisa ovamile emhlabeni 55 Hz. Umkhawulo kuvunyelwe voltage ukuphambuka 15%. onobuhle Abaningi thyristor abalawuli anemisila izinzwa ekhethekile. Amadivayisi ezivamile babonwa esibhalwe ukuthi "RTS". Zingasetshenziswa at lokushisa kusuka -50 kuya +50. Ukufakwa ukulawula isivinini fan pretty elula. Kulokhu, inkomba ijubane ukujikeleza wayenike.

Izici imvamisa abalawuli

Ngokuvamile, ukuvama isilawuli isivinini fan kuyinto ukwazi ukubhekana voltages eliphezulu kakhulu. Lapho ijubane ukujikeleza sishintshwe ngokushintsha zamanje. Ngokuvamile, lolu hlobo zingatholakala ku ezihlukahlukene air-conditioning izinhlelo. Engeziwe imvamisa nabalawuli mahle amadivayisi baqashwe emoyeni ukupholisa. Ngokuvamile, amadivaysi ezingenhla eziyinkokhelo lilula.

Izimpawu imvamisa nabalawuli

Zidla on inethiwekhi nge voltage ka 220 V. Le amandla okukhipha fan ngesikhathi esifanayo akufanele idlule Watts 500. Ubuningi ukumelana Umlawuli isilinganiso kulingana ohms 300, kanye isignali elawula uhlelo kungenziwa waqonda ku-10 V Ngokushesha kuhla amandla isilawuli iyunithi 3 B.

Standard kudivayisi isethi siqukethe ikhebuli esibulalayo block isikulufa hlobo. Fuses kule divayisi ayatholakala nge amandla samanje hhayi ngaphansi kuka 3 Degree yokuvikela e onobuhle eziningi isigaba "IP21". Ezisetshenzisiwe imvamisa isilawuli isivinini fan can at lokushisa kusuka -10 kuya +30.

Transformer fan abalawuli

Transformer isilawuli 12b isivinini fan isetshenziswa kuphela ephezulu amandla owodwa isigaba noma ezintathu okhombisa izinjini. Ngqo linemibhikisho ukuqapha wenziwa ngendlela stepwise. Kulokhu, kungenzeka ukuba amise ukubambisana othomathikhi. Temperature nezinzwa ukufakwa onobuhle eziningi.

Ngaphezu kwalokho, ungakwazi ukukhetha transformer elawula abalandeli ne nomswakama izinkomba. Nokho, amandla abo kungashintshwa usebenzisa timer. Lezi amadivayisi zixhunywe usebenzisa ngezikulufo. Idivayisi kungenziwa ifakwe izibopho esikhethekile eqinisa kwakwakhe. Njengoba i-contact ezethula ezikhumulweni ayatholakala. amakhebuli kagesi njengoba standard ifakiwe.

Ukumelana transformer Umlawuli imi ohms 400. Uma lokhu isignali ukulawula ibonwa ukuba 4 V Ngaphezu kwalokho, kufanele kuphawulwe load yakho iphezulu kakhulu edluliselwe okukhiphayo. Amandla ukusetshenziswa zedivayisi kuyahlukahluka okuyisilinganiso sabangu-12 V Ngokuvamile, lezi amadivaysi okulula okukhulu uma ziqhathaniswa imvamisa nabalawuli abalandeli ezibizayo.

Triac isilawuli izinhlobo

Triac control ijubane fan apharathasi kuyinto kuyinkimbinkimbi kunazo zonke izinhlobo ezibalwe ngenhla. Isetshenziselwa ukulawula kumadivaysi amaningi ngesikhathi esisodwa. Kulokhu lezi izinjini ingafakwa zamanje njalo futhi kushintshana. Ngqo ushintsho ijubane kwenzeka ngempela ngokushelela.

Kubalulekile futhi ukuqaphela ukuthi ibanga voltage ubanzi kakhulu. Special ukucacisa ukuma-isigaba imodeli Regulator. Ukuze wehlise ivolumu bokusebenza idivayisi mshini has a bushelelezi capacitor ekhethekile. Ukufaka triac isilawuli kungaba ezahlukene. Okuvame kakhulu ubhekwa entabeni ezishaywayo, kodwa abakhiqizi abaningi bayakwazi ukunikeza Ukukhweza for nenkanuko edlulele kumadivayisi angaphandle.

Umgomo we operation triac isilawuli

Ukucubungula okuphelele kwayo yonke imininingo ubelokhu ngokuphelele sekhompiyutha iyunithi. Ngakwelinye ihlangothi, batawedlulisela isibonakaliso triac control ijubane fan has a inzwa. It ixhuma nge i itheku ku iphaneli ohlangothini. Ngaphezu kwalokho, inzwa siqhutshwa ukuqapha lokushisa kudivayisi. Kulesi ukumelana block ngokuqhubekayo adjustable.

Ukuqeda ukuphazamiseka evelayo ngesikhathi ukusebenza, kukhona isihlungi digital. Futhi kungaba ucime yamahhashi ishayela ohlelweni. Resistor isilawuli isivinini fan unesibopho wamanje uguqule. Ngenxa yalokho, i-ukwanda kokutheleleka kudlange kakhulu inzwa lokushisa sinikeza isignali ukunciphisa voltage. Ngaphezu kwalokho, eziningi incike ecacisiwe izilungiselelo triac isilawuli. Ngakho, ngokubeka izinhlelo, ungakwazi ukushintsha value eziyisisekelo.

Ukufaka triac isilawuli

Ukusetha ijubane isilawuli fan 220 Kufanele unqamule ukuxhumana ngokuphelele inethiwekhi. Ngaphezu kwalokho, kubalulekile ukususa iphaneli eziyisisekelo, okuyilona elisebenzayo phambi idivayisi. Kungaleso sikhathi kuphela lapho unganqamula ikhava iyunithi. Isinyathelo esilandelayo ukufaka inzwa lokushisa ukuze itheku. Ukuze uthole amandla ompompi kumele ayejwayele iyunithi wesifunda.

Ukuxhumeka okuqondile ne motor fan wenziwa esebenzisa ngci babashayeli uhlobo balahleke. Khona-ke umoya capacitor esitshalweni eseduze inzwa lokushisa. Kubalulekile kakhulu ukuhlola kudivayisi amapayipi isokhethi. Ukuze uthole uxhumano omuhle akufanele kube khona noma ikuphi ukungcoliswa. Kungenjalo isiginali ngeke sifinyelele microprocessor iyunithi. Ukuhlanza isixhumi qualitatively, Ochwepheshe zisebenzisa izindlela zokususa zethusi oxide.

Ngemva ukulungisa phezulu ikhava olungavikelekile ingxenye nivame nokunamathisela i conductivity enhle ezishisayo. Njengomthetho, sebenzisa ithuluzi kuphela ngesisekelo non-omiswe. Lezi zingqimba ohlangothini ogibele latches umlamuli simistrovogo. Kusukela ngenhla nazo ethe njo ukwahlukanisa. Kulokhu-ke ububanzi strip akufanele kube ngaphansi kuka-10 mm. Khona-ke control ijubane 220 fan ingalungiswa phezu ichopho. Kubalulekile banake Izintambo zikagesi ezisobala kanye bamba lapho lisebenze ikhiyiwe. Isinyathelo sokugcina ukufakwa ukuxhuma kwamandla. Ngemva kokuhlola isixhumi ukuze sithole amandla okwenza ukufakwa Isivivinyo.

Amamodeli kubalandeli ne izinjini indlela

Isici esiphawulekayo onobuhle eziningi control ijubane stepless. Fan kumele abe wamanje okuzisholo ezingekho ngaphezu 6, futhi imvamisa isilinganiso - esifundeni 45 Hz. Isilawuli ugesi kuyinto inethiwekhi 230 V Degree yokuvikela iye yalungiselela ikilasi "IP 54". Ukuze uhlelo uhlelo kuyinto isilawuli ekhethekile.

Ngenxa nabalawuli ngenhla, injini ukuqala Kwenziwa ngempela ngokushelela. Umphini ke uzungeza at a imvamisa njalo. Yamanje Ukuvikelwa motor efakwe onobuhle eziningi. Ijubane ubuncane ukusetha isilawuli ngangokunokwenzeka.

Lesi sici nobuntu abalawuli nge potentiometers ekilasini VM futhi VX. Setha kabusha isilawuli isivinini ibhodi ilawulwa, futhi ungabona imisebenzi yakhe ukukhanya-likhipha diode izinzwa. Ukuze ekulinganiseni voltage ngesikhathi imoto emazombezombe has a microcontroller. Ngokuqeda isigaba baphawula ingafinyelela okusezingeni eliphezulu ekusetjentisweni kwemandla ngalokuyimphumelelo.

nabalawuli heater

UMlawuli-heater isivinini fan ungakwazi kakhulu ukunciphisa umsindo kusuka ekusebenzeni kwe-motor. Ngesikhathi esifanayo inikeza elula control kwangaphandle. Ngenxa yalokho, ungase ukwazi kakhulu ukunciphisa ukusetshenziswa kukagesi.

Ngaphezu kwalokho, ingxenye bafake ngempela encishisiwe ngokulungisa imvamisa mkhawulo. Lubhekele ke ohlelweni ishayela ububanzi modulator. Operating Umlawuli lwamanje emhlabeni 0.7 A. esiphezulu amandla okukhipha nxazonke 550 Watts. Wokufaka impedance nabalawuli alesi sigaba inakekelwa ngezithuba 200 ohms. Uma lokhu isignali ukulawula ibonwa at 8 V. Le ikhebula ngokuvamile yayihlanganisa kusetshenzisiwe kwakuvikela.

Umthwalo umugqa okukhiphayo isilinganiso avunyelwe 3 A. Futhi, ukusetshenziswa kwamandla idivayisi uhla kusuka 4 kuya kwezingu-8 V. Le fuses e nabalawuli for air conditioning system efakwe ekilasini FUSE, ziyakwazi nokukhawulela zamanje egeleza 5 A. I degree of ukuvikelwa ngesikhathi banalo ikilasi "IP21". Okuhambisana cishe wonke amamodeli we uhlelo air conditioning kuphela ngaphandle - esebenzisa ngezikulufo. Ngokuvamile, abasakwazi compact futhi inesisindo esincane kakhulu.
