Ukulawula isantya se Fan. Ulawulo lwezantya ezithatha isivinini

Enyanisweni, umlawuli wejubane lomqhubi wenza umsebenzi wokutshintsha i-voltage esetyenziswa kwisixhobo. Ngokweenjini, isixhobo esingasentla sinomthwalo wokutshintsha ukuhamba. Ubume bexesha langoku buyahlukahluka kakhulu.

Siyabulela kubalawuli bebalandeli ukuba izixhobo zombane zinokuhlala iminyaka emininzi. Oku kungenxa yokunciphisa ukunxiba kunye nokuqabhuka kwezinto ezibalulekileyo zeyunithi. Ukongezelela, kukho ithuba lokunciphisa ukusetyenziswa kombane. Ngako oko, kwixesha eliphezulu, umqhubi unzima kakhulu.

Abalawuli befayili

Umlawuli wesivinini sejubane (uboniswe ngezantsi) unokufakwa kuphela kwisixhobo esisodwa se sigaba. Kwezixhobo zingabonwa yinkqubo yokukhusela ethembekileyo. Ngombulelo, umlawuli wokulawula isantya esithintela isithintelo sokuthintela ukutshiswa kwezinto ezibalulekileyo. Ngenxa yoko, iinguqulelo zilawulwa ngokutshintshela umda.

Njengomthombo wamandla kwesi sixhobo sinomnatha kunye nombane we-220 V. Ngelo xesha, i-frequency frequency ihamba nge-55 Hz. Ukuphambuka okukhulu kwamandla kuvunyelwe kwi-15%. Uninzi lwemodeli ye-thyristor regulators zixhotyiswe ngeenzwa ezikhethekileyo. Izixhobo eziqhelekileyo zizo zibhalwe "RTS". Zingasetyenziselwa ukushisa ukusuka kwi -50 ukuya kuma-50 degrees. Kufakelo, ulawulo lwejubane lomqhubi lulula. Ngelo xesha, isalathisi sejubane sinikezelwa.

Iimpawu zabalawuli bexesha

Njengomthetho, umlawuli wesantya sejubane lomqhubi uyakwazi ukujamelana nombane ophezulu. Kule meko, isantya sokujikeleza sitshintshwa ngenxa yenguqu kumandla akhoyo. Ngokuqhelekileyo olu hlobo lunokufumaneka kwiinkqubo ezahlukeneyo zemoya. Ukongezelela, abalawuli bee-frequency bafaneleke ngokufanelekileyo kwizixhobo ezisebenza emoyeni. Ngokubanzi, izixhobo ezingentla zibukeka zilula.

Iziganeko zolawulo lwexesha

Bondla kwi-intanethi ngombane we-220 V. I-output power of the fan ngexesha elifanayo akufanele lidlule ama-watts ama-500. Ubunzima bokumelana nomlawuli kumlinganiselo we-300 kOhm, kwaye isalathisi sokulawula yesistim singabonwa ukuya kwi-10 V. I-unit control regulator idla ngokufanelekileyo amandla amathathu.

Isethi esimiselweyo yefowuni iqukethe ikhefu, kunye nesiphelo se-screw-type. Iifom edivaysi zifumaneka ngamandla okwangoku angama-3. Iqondo lokukhusela kumanqaku amaninzi lusekwe kwiklasi "IP21". Umlawuli wesantya sejubane lomqhubi angasetyenziswa kumaqondo okushisa ukusuka -10 ukuya kuma-30 degrees.

Abalawuli bamatshini abaguqukayo

Umlawuli wesantya se-transformer ye-fan 12V isetyenziselwa kuphela amandla aphezulu okanye amanqanaba amathathu. Ukulawulwa ngokuthe ngqo kweenguqulelo zenziwa ngendlela efanelekileyo. Ngelo xesha, kukho ithuba lokuseka ngokuzimeleyo. Iisenjini zokushisa zifakwe kwiimodeli ezininzi.

Ukongeza, kunokwenzeka ukuba ukhethe abalawuli befester transformer kunye nezibonisi zomswakama. Ngelo xesha, amandla abo angatshintshwa ngexesha lexesha. Ezi zixhobo zichanekile ngezikrini. I sixhobo sinokuxhotyiswa ngokulungelelanisa okukhethekileyo ukuqiniswa koxhumano. Njengombono wokugcina, kukho iipedals. Izixhobo zombane zifakiwe kwiikiti eziqhelekileyo.

Ukumelana nokuguqulwa komlawuli we-transformer kunokumelana ne-400 kOhm. Kule meko, isalathisi sokulawula sithatyathwe ukuya kwi-4 V. Ukongeza, umthwalo ophezulu wesiphumo esidluliselweyo kufuneka uqatshelwe. Ukusetyenziswa kwamandla kwesixhobo ngokulinganisela kuyahlukahluka malunga ne-12 V. Ngokuqhelekileyo, ezi zixhobo zinzima kakhulu xa zithelekiswa nabalandeli beefrikanti kunye nabalandeli ababizayo.

Iindidi ze-Triac zolawulo

Ulawulo lomqhubi wezantya zeso sixhobo esona sisisigxina kuzo zonke iintlobo ezingentla. Isetyenziselwa ukulawula izixhobo eziliqela ngokukhawuleza. Kule meko, ii-motors ziyakwazi ukunyuka kuzo, kunye nokunye okukhoyo. Ukutshintsha ngokukhawuleza isivinini ngokukhawuleza.

Kwakhona kubalulekile ukuba uqaphele ukuba uluhlu lwamandla lukhulu kakhulu. Imilinganiselo yesigaba esithathu yabalawuli iyahluka ngokuchanekileyo okuchanekileyo. Ukunciphisa umthamo wesandi kwi sixhobo, ifowuni ine-capacitor special to capacitor. Ukufakwa kolawulo lwe-Triac kungahluka. Eyona ndawo ixhaphakileyo iyakhutshwa, kodwa abaninzi abavelisi banako ukunikela ngokukhawuleza kokulungiswa kwangaphandle kwesixhobo.

Umgaqo wokusebenza komlawuli we-triac

Ukusetyenziswa kwayo yonke idatha kulandelwa yunithi ye-microprocessor. Ngaloo ndlela, inzwa isetyenziselwa ukudlulisela umqondiso kwi-triac yokulawula isantya somqhubi. Ixhunyiwe kwi-inlet kwicala eliphambili. Ukongeza, i-sensor ilinda ubushushu befowuni ngexesha lokusebenza. Ukuxhatshazwa kweyunithi kulawulwa rhoqo.

Ukuphelisa ukuphazamiseka okwenzeka ngethuba lokusebenza, kukho isihlunu se-digital. Iyakwazi ukunqanda ukuqhuma kwe-pulse kwi-system. Ukuchasana nomlawuli wejubane lomqhubi kujongene nokuguqulwa kwangoku. Ngenxa yoko, xa iqondo lokushisa liphakama ngokukhawuleza, i-sensor ibonisa isidingo sokunciphisa umbane. Ukongezelela kakhulu kuxhomekeke kwizicwangciso ezilungiselelwe umlawuli we-triac. Ngaloo ndlela, ngokweprogram, iziseko ezisisiseko zinokutshintshwa.

Ukufaka umlawuli we-Triac

Ukufakela umlawuli wesantya se-speed 220V, unqamle ngokupheleleyo ukunikezelwa kwamandla. Ukongezelela kubalulekile ukususa ipaneli ephambili, ephambi kwesixhobo. Kuphela ke unako ukufumanisa ikhava yunithi. Isinyathelo esilandelayo kukufakela inzwa yeqondo lokushisa kwi-inlet. Ukuxhuma inkqubo yokunikezelwa kwamandla, kufuneka uzifundele umzobo wesiphaluka kwisixhobo.

Ukuxhamla ngqo kumbane wombane we-fan uyenziwa ngoncedo lwezingcingo ezifakwe kwizinto ezinobungozi. I-condenser yomoya ivuliwe, ekhangelelene neqondo lokushisa. Kubaluleke kakhulu ukujonga isiseko esisiseko sesixhobo. Ukunxibelelana kakuhle akufanele kubekho nongcoliseko. Ngaphandle koko, uphawu aluyi kufumana i-blockprocessor block. Ukucoca ikhonkco ngokufanelekileyo, iingcali zisebenzise ukususa i-oxide ye-copper.

Emva kokufumana isiqulatho esiphezulu, indawo engakhuselekanga ifakwe kwinqanaba lokuqhuba kakuhle. Njengomthetho, sebenzisa i-remedy kuphela kwi-non-drying basis. Amacwecwe angamazantsi aphethe i-shimistrovogo regulator ehlangene nelokhi. Baye baxutywe phezulu kwi-thermal insulation. Ububanzi bomqhawulo akumele kube ngaphantsi kwe-10 mm. Emva koko, umlawuli wesantya se-speed 220V unokumisela kwikhuselo. Kubalulekile ukubeka ingqalelo kwi-wiring kwaye ungayifaki ngexesha lokulungiswa kwesixhobo. Isinyathelo sokugqibela sokufakela ukuxhuma inethiwekhi yamandla. Emva kokuvavanya umxhasi wokufumana amandla, kufuneka wenze uvavanyo lokufakwa.

Iimodeli kubalandeli abanamashishini asynchronous

Into ehlukileyo yamanqaku amaninzi kukulawula ngokukhawuleza. Ngaloo ndlela abalandeli mababe ne-current rate engaphezulu kwe-6 kwaye, kunye ne-frequency frequency-malunga ne-45 Hz. Amagunya okubonelela ngogunyaziso yintanethi kunye nombane we-230 V. Iqondo lokukhusela baneklasi "IP 54". Umlawuli okhethekileyo ufakelwe ukwenza inkqubo.

Ngombulelo kubalawuli abalapha ngentla, i-injini-start-up ingcono. Kule meko, i-shaft ijikeleza ngokuphindaphindiweyo. Ukukhuselwa kwangoku kweeMoto kufakwe kwiimodeli ezininzi. Isantya esincinci singasetwa ngumlawuli.

Lo msebenzi uqhelekileyo kubalawuli abanokubakho kwi-class VM neVX. Ukusetyelwa kwejubane kulawulwa yibhodi yomlawuli, kwaye uyakubona ukusebenza kwayo ngama-LED sensors. Ukuzinzisa umbane kwi-motor winding kukho umlawuli omncinci. Ngokuphelisa ukuphuma kwesigaba, ukugcinwa kwamandla aphezulu kunokufezekiswa.

Ulawulo lwezithuthi

Umlawuli wejubane lomqhubi unokunciphisa kakhulu ingxolo evela kwimoto. Ngexesha elifanayo, linikeza ukulawula kwangaphandle okulula . Ngenxa yoko, unokunciphisa kakhulu ukusetyenziswa kombane.

Ukongezelela, ukugqoka kwimihlaba kuncitshiswa kakhulu ngokulungisa utshintsho oluthile. I-modulator ye-pulse width ijongene nale nkqubo. Ukusebenza okwangoku komlawuli kuyashintsha malunga ne-0.7 A. Amandla amakhulu avela kumalunga nama-550 watts. Ukungqinanga kokufakelwa kwabalawuli beli klasi kugcinwe kwi-200 kOhm. Kule meko, umqondiso wokulawula uqondwa kwinqanaba lika-8 V. Ikhebula, njengombandela, lifakwe kwisethi epheleleyo yohlobo olukhuselekile.

Umthwalo kwimiphumo yemigangatho iphakathi kwemitha eyi-3. A. Ngokubakho, ukusetyenziswa kwamandla kwesi sixhobo kuluhlu lwe-4 ukuya ku-8 V. Iifom kwiimpawu zokumisa umoya zifakwe kwiklasi yeFUSE, kunye nelo xesha lokukhawulela abakwaziyo ukudlula kwizinga le-5 A. Iqondo lokukhuselwa Kukho iklasi "IP21". Phantse zonke iimodeli ziqhotyoshelweyo kwinkqubo yokumisa umoya-moya kuphela yindlela yokwangaphandle - usebenzisa i-screws. Ngokuqhelekileyo, zincinci kwaye zincinci kakhulu.
