Magnetron: intshukumo kunye umgaqo kwefowuni

Ukuze ufumane intlokoma abucala ephakamileyo, sebenzisa magnetrons. zombane kunye nemagnethi yenze ngamandla aphezulu. Ngenxa yoko Iingoma eliphezulu-frequency kwenzeka. Asetyenziswa rhoqo uhlobo isixhobo yi Multiresonator. Esi senzo magnetron kwi elektroni emasimini nje ezintathu:

• umbane;
• magnetic;
• Microwave.

Magnetron: kwabonakala nendlela

Kuba ixesha lokuqala eli gama lisetyenziswa ngowe-1921 yi-American yamachiza A. Hull. Uphando lwakhe kunye imifuniselo kwaqhutyekwa ngayo, ekhokelela ekuveleni iintlobo ezininzi magnetrons, eyaqala kusetyenziswa elektroniki. I-patent yale yasungulwa yayifunyenwe Jacquet ngo-1924. Yaba nguye owasungula magnetron mihla, isimiso lokusebenza lisekelwe impefumlelwano amasimi ezimbini.

Kule minyaka ilishumi zilandelayo ekuphuhliseni magnetron ukwenza microwave. Eyona njongo ephambili ukunyusa amaza oscillation, leyo inokwenziwa kuphela yi-nzulu yiSoviet. Ke landa inani lokuqala kabini, usebenzisa ngobhedu njengento anode.

device

Heart magnetron anode block sakhiwa itankana sobhedu umngxuma ngaphakathi. Kwiziko layo, kukho nemingxuma, ukuba angabi nemingxuma inkqubo lesangqa. Embindini ka anode inomngxuma ngalo ngayo ukudibanisa umbane. Kwakhona, lo anode of elidityaniswe kuyo le cathode. Nguye ntambo, itshiswa kwaye udlula phakathi anode. Ukuqinisekisa imveliso eliphezulu oscillation output lisetwe a resonator enjalo. Ngaphakathi ongenawo kwibloko anode. Kuba fin wayo okupholisa ibekwe phezu kobuso radiators.

Beka iyunithi ukuze okokuba waxwilwa phakathi umazibuthe kudala mhlaba otsalayo wamandla ngokwaneleyo. Ukuseka le ombane phakathi kwe anode kunye cathode, yaye ukuze terminal kakuhle umthetho ibekwe kufuphi anode. Electron evela cathode aqalile ukuya ngenxa yesenzo intsimi kombane. Kufuneka uye kulo anode kunye magnetron, umgaqo amanyathelo apho kukho mhlaba otsalayo, ubuyela sihlaba ukuya cathode.

Ukuphumeza lo ukusebenza, xa electron ukuhambisa ecaleni kwesangqa ochazwe yaye ngaloo ndlela ezikufutshane anode, kodwa wabuya, kunokwenzeka, ukuba bagcine ukuba iimeko ezithile kwiinkalo ezimbini ezinxulumene. Kule meko, i anode maqhezu encinane kuphela zonke elektroni ezikhutshiweyo kula cathode.

Ukubuyela kule cathode le electron kuguquliwe. Le nkqubo iqhubeka, ukwakha kufuphi anode umwisele ngohlobo amakhonkco. umyalelo onjalo uqala ukuba luyasekwa kwisisu nganye, kukho intlokoma ophezulu rhoqo undamped. okunzulu ezinjalo angarhoxa nocingo iingcingo, amalungiselelo nangayiphi na ukuqanda. Emva ezi intlokoma ukuba idluliselwe waveguide (okanye umgca yafakwa).

Magnetron zingabizwa isixhobo microwave, oko wenkunkuma, emoyeni, isindululo of elektroni kulo lwenzeka kwiinkalo ezimbini: elektroniki kunye ngemagnethi. Oku kudala umgaqo magnetron yokusebenza kwezi nkalo zimbini, nto leyo yenze eyesithathu - le microwave.

isicelo

Baya ungasetyenziswa elektroniki. Ngokomzekelo, xa kumalungiselelo iimephu radar. Ukuza kuthi ga ngoku, le magnetron kufuneka luqulathe igama hayi kuphela uphondo feed, kodwa ukususela kugqame ezizekelisayo. Ukusebenzisa la ekumgangatho ophezulu yi generated ulawulo mfutshane ukubetha microwave radiation. Inxalenye amandla lubonakala, ibuyiswa kwi waveguide kunye uthi wayithumela receiver. Emva processing, i data evela kwi imaphu ye-radar.

Isetyenziswa kubomi bemihla ngemihla

Emlilweni, ezo zisekelwe iimayikhroweyivi, isimiso ukusebenza ezahlukeneyo kancinane. Le magnetron ye-onti uye ekupheleni waveguide ukuba sokuquqa kwerediyo lokuvula ngaphaya enziwa kwi gumbi zokupheka. Kubalulekile ke ngoko ukuba ibandakanye nesitovu kuphela kukho ukutya kuyo. Ngaphandle kwale meko, amaza bemi kuya kubangela arcing, ekubeni amaza ngemagnethi musa simunce, baza babuya. Ukuba ihlala ixesha elide, i magnetron kulula ukuba aphule. Izinga apho ukutya microwave elungiselelwe eziko, kuxhomekeke ngqo kwi amandla magnetron.

Uninzi oveni microwave kukho umthamo watts 700 ukuya 850. Oku kuya kuba ngokwaneleyo ukuba ungalipheki nendebe le yamanzi kwimizuzu nje 2-3. Magnetron for microwave "uSaturn", kuxhomekeka imodeli, unokuba bamandla ezahlukeneyo. Ukukhetha le microwave le nkampani, ungenza uyiqala ngokuthelekisa magnetrons, uze nemisebenzi eyongezelelweyo.

ukuthenga microwave

Xa uthenga i oven kufuneka ukuba umgaqo osebenza ngayo. Abaninzi uqaphele ukuba le ndlela, xa ngempazamo acinga ukuba ngumthombo radiation. Enyanisweni, lo mgaqo le microwave, ukuba igama libonisa. Microwave - ukuba ezinye, njengokuba "rhoqo ultra-high." Yena radiation, Kakade ke, oku angakanani, kodwa ukuba indlela enjalo kufuneka silumke.

Microwave ngokwayo zisuka lukhuselwe abanye kwimitha microwave. Le eziko lixhotyiswe zincwadi Womenzi okhethekileyo, nto leyo likhubaza magnetron ukuba ucango kuvulwa. Gqibezela lo mgaqo yomsebenzi magnetron yazo kukuphuhlisa iimayikhroweyivi akayi kuba nako, ukuba waphula imithetho yokusebenza. Ukuba ufake eziko, umzekelo, isitya otyhidiweyo, nje iza ukukhubaza isixhobo yonke.

Amaza ezivela oveni microwave aye ngaphandle akukho ngaphezu kweemitha ezintlanu. Ngenxa yoko, ngelo xesha, xa isebenza, kungcono ukuhlala kude. Nangona kunjalo, ubume Amakhitshi ezininzi izindlu musa ukuvumela oku, kuba imfuno ukuya kwelinye igumbi.

Intsimi magnetic of a licwecwe kumo ukutya obekwe kwi oven. Ngaphaya koko, inkqubo zokufudumeza ithatha indawo ngqo ngaphakathi imveliso, ngaloo ndlela kuncitshiswa ixesha zokupheka ukuya kwimizuzu embalwa. Akukho mfuneko dish pre-ubushushu, nto leyo ukutya.

Ukuze ufumane iziphumo ezintle, kufuneka ukwazi ukupheka zokupheka unobuqili iimveliso ezithile. Ngenxa yokuba ixesha buyadlula, kwaye isixhobo microwave oveni ayitshintshi, siya kucinga phambili kunye nokudityaniswa okuqhubekayo amakhitshi kwabathengi abaninzi.

Ukuthenga magnetron microwave

Ukuthenga wena a magnetron, kuyimfuneko ukwazi uphawu. Ukuba wenze impazamo uthenga le magnetron kwi microwave i LG, kufuneka ukuba uqhelene oko bakuko. Amandla olubuthathaka kakhulu ukusuka 2M213 magnetron. Yena amandla imveliso kwi umthwalo eqhelekileyo kwaye 700 no-600 W, ngokulandelelana, anodic intsingiselo - 3,95 kVp, kwaye rhoqo - 2460 MHz.

Magnetrons kunye ixabiso angumndilili ezimbalwa. Eyona kuzo zezi: 2M214. Kulo mzekelo, rhoqo ixabiso anodic aphakeme kancinci - 4.20 kVp. Isiphumo kwamandla umthwalo kunye ongumzekelo - 1000 no 850 W, ngokulandelelana.

Amaxabiso liphezulu parameters kwi marki2M246 magnetron. Xa amaza efanayo njengoko anode mkhulu - 4.40 kVp, i-avareji amandla imveliso phantsi komthwalo - 1150 W, boqobo - 1000 W.

Ngaba kunokwenzeka ukuba kufakwe endaweni izandla zabo

Naluphi na uhlobo magnetron ye-onti LG, ungenza endaweni efanayo abanye mveliso, ezifana "Samsung". Ngokufanayo, umntu endaweni magnetron for microwave "Samsung" best amandla element kwenye inkampani. Ukuba model oveni microwave ndyangu kukhululwa ixesha elide, ngoko kufumana inxalenye ohambelana uphawu kunzima kakhulu. Mhlawumbi umenzi iye isuswe olu hlobo kwimveliso.

Kodwa nokuba uyayazi na umgaqo osebenza kuyo magnetron, kufuneka sizibandakanye ukulungisa izixhobo ekhaya ngokuzimeleyo.

Thenga i magnetron ukuba oven 2M218 JF Daewoo ngabanini, eyalela ezivenkileni ezizodwa okanye ngqo evela kumenzi. Kubiza malunga 2 amawaka engange.

Ngenxa yomsebenzi microwave

Ayaphola ukutya oven lumi ngolu hlobo lulandelayo: ukutya iqulethe iimolekyuli zamanzi, oko kukuthi, nayo, iquka amasuntswana ngokuqinisekileyo ityala kwaye embi. iimolekyuli zinjalo dipole, ngokuba ababhexeshi ezilungileyo ngamaza ombane.

isiphelo

Le breakage rhoqo eziko microwave - Ukuqhekeka magnetron. Thenga i magnetron kwi microwave LG (njengoko, eneneni, kunye nezinye nabavelisi data izixhobo zombane zasekhaya) kwaye endaweni nawo uwedwa kakhulu yingxaki. Nokuba kukho into efanelekileyo ukuba oko inkosi kuphela.

Phambi kokuba uthenge isixhobo exabisa ixabiso layo kuthelekiswa iindleko microwave. Kudla ukuba balungise uya kubiza ngaphezu bathenge. Soloko ulijonga lo mba.

Ngoko ke, siye safumanisa ukuba kutheni kukho into efana magnetron, kwaye esetyenziswa Ziziphi iinkalo kuyo.
