Linanena bungwe windings ogwirizana mu kufanana kwa magnetron lapansi.

magnetron

Akukonza uvuni mayikirowevu ndi manja ake, ayenera kulabadira magnetron lapansi. Mu dongosolo la chida, iye atenge mbali ya mtima. Amalima cheza mayikirowevu kuti kutenthetsa zakudya mkati m'chipinda.

mchitidwe uwu limapangidwa angapo zigawo zikuluzikulu:

• Redieta;
• resonant M'mimbamo;
• ndi anode;
• cathode.

Ndi chipangizo chipangizo, choncho fufuzani Kutukula ake ayenera idzachitika mu nkhani ya mavuto mu ntchito ya luso. Pamene kuchokera maukonde kukana ng'anjo magnetron kufufuzidwa ntchito choyezera chida.

Ngati kudalira zambiri matenda, zidzakhala bwino kaya chipangizo ayenera m'malo, anakonza, kapena chifukwa cha kulephera ndi zina chigawo gawo.

Mophweka vuto

Chichitike, mayikirowevu kukonza manja awo amachitidwa popanda m'malo mbali ndi mwai zovuta. Izi zimachitika pamene ena zochitika zomwe zinatipangitsa sanali ntchito zamakono.

Chifukwa cha vuto ndi zina osakwanira voteji. Ndi kuchepetsa chizindikiro 20 mu kungachepetse mlingo wa magetsi kapena ng'anjo ntchito ndi kutsazikana. Vuto la kotunga uninterruptible mphamvu.

magetsi zimamuchulukira komanso amatumikira chifukwa cha kulephera kwa mayikirowevu lapansi. Pakuti hardware wamphamvu bwino kubweretsa kubwereketsa osiyana.

Pamene chitseko latch breakage mankhwala bwino mkangano. Ndi mwamphamvu chatsekedwa mayikirowevu.

Chifukwa cha kusasamala katundu owerenga kuti anali ozizira, kodi chabe usavutike pa nthawi yolakwika. Mwachitsanzo, mayikirowevu kuti defrost nyama, ndiyeno mode anawamasulira mu mphamvu zambiri.

Ngati chifukwa cha kulephera amalimbikira njira pamwamba, m'pofunika kuti agwire ntchito ochulukirapo: onani machitidwe a magnetron ndi, capacitor, mafyuzi ndi mkulu-voteji diode.

lama fuyusi

Self kukonza microwaves kuyamba ndi kuchotsa (ngati foloko kuchokera maukonde) za kumbuyo nyumba chivundikirocho. Amasonyeza breakage wa lama fuyusi akhoza blackening kapena amatopa kwa filament mkati. Kodi m'malo ndi chidutswa latsopano. Childs, mu uvuni mayikirowevu ali mafyuzi awiri.

Zikatero, pamene mbali Sikuti, muyenera kugula izo kwa wogulitsa a. Tiyenera kubweretsa sanali malonda asilikali olondera mfumu monga Sankhapo adzakhala ndi chimodzimodzi chipangizo chomwecho. Izi adzaonetsetsa ntchito lolondola ndi abwino zida.

Kodi si ntchito kukonza kulephera iyi, "nsikidzi" mwa waya woonda. Zingayambitse moto. Mwina izi zikuchitika si mkulu. Choncho ndithu ayenera kugula lama fuyusi yachibadwa. mtengo wake ndi otsika.

capacitor

Pamene pa ntchito ya phokoso mayikirowevu kupunthwa ndi kugogoda extraneous, kuswa chifukwa zotheka ndi capacitor. Kukonza zinthu pa mauvuni awo mayikirowevu, ohm mita chikugwirizana ndi capacitor lapansi. Ngati singano chipangizo ali wokanidwa, zikutanthauza kuti katunduyo akugwira ntchito. Apo ayi, izi ndi chifukwa cha vuto la. matenda ake ndi osavuta. Ohmmeter chingathandize kukonza uvuni mayikirowevu ndi manja ake. Chitsanzo cha ntchito zake ndi zothandiza mwatsatanetsatane.

Malinga ndi malamulo chitetezo capacitor pamaso macheke ayenera yotsitsa. Ali mu chikhalidwe mlandu, ndi kutiletsa kukhudza dzanja lake kapena screwdriver. Si bwino kwa anthu.

Mkulu-voteji diode

Ngati mkati mwa Kutentha chipinda kumeneko limafotokoza fumes, utsi, nsakali zimapezekabe, angathe kuswa mkulu voteji diode. Chitsanzo cha kulephera kwa gawo lino muja phokoso pamene anatembenukira ndi nkhonya ya lama fuyusi. Tsimikizani kuti mfundo mukhoza kugwiritsa ntchito mkulu-voteji capacitor. Siziyenera usavutike.

Ngati kulephera chifukwa Kulephera kwa diode mkulu-voteji, muyenera kugula gawo latsopano. Chifukwa zovuta chipangizo ake okha, linanena bungwe limapereka kukonza mauvuni mayikirowevu. Mwachidule ambuye akatswiri a ayamikira kumabweretsa mfundo yakuti akale mkulu-voteji diode zovuta kukonza. M'pofunika m'malo katunduyo ndi kuona ntchito za capacitor mkulu voteji. Ngati iye sakhala otentha, breakage likuchotsedwa.

Kuwonongeka kwa magnetron ndi

The ofunika kwambiri chipangizo kupereka mayikirowevu opareshoni, ndi magnetron. Iwo amapanga ndi funde la pafupipafupi ultrahigh (UHF). m'malo mwake ingathe kuposa zina zilizonse m'malo. Nthawi zina, ndi zosayenera kukonza mauvuni mayikirowevu malinga ndi kafukufuku wa akatswiri.

Chizindikiro kulephera gawo amaperekedwa mkati phokoso ng'anjo. The chakudya si usavutike, koma ntchito zonse zimagwiridwa zowoneka. Mkati mwa Kutentha chipinda ndi kuwala, ntchito mayikirowevu.

Kukonza manja anu amayamba ndi ulendo wa magnetron lapansi. Ngati izo siziri kuwoneka mwaye kapena ming'alu, m'malo ndi ohmmeter ndi. Nsembe mchitidwe m'malo mwa ndendende latsopano chomwecho. Magnetron ayenera kukumana magawo chimafotokozera chitsanzo mayikirowevu. Sinthanitsani ndi mtundu wina wa chipangizo ng'anjo ndikoletsedwa.

Zimayambitsa kusokonezeka

Amayambitsa za magetsi kunyumba wonongeka ntchito molakwika zochita zake. Pofuna kupewa malfunctions tsogolo ndi mavuto mu ntchito mayikirowevu, muyenera mutidziwe ndi zina mwa zifukwa zambiri kulephera. Njirazi ndi monga:

• kwanyengo chakudya mu mbale zitsulo, kapena kukhalapo kwa zinthu zimenezi m'chipinda (mwachitsanzo, spoons kapena mafoloko);
• kulolerana mu mayikirowevu popanda chakudya;
• Kutentha mazira yaiwisi kapena mankhwala ena amene mchikakamizo cha matabwa mayikirowevu kwa amaphulika.

Chimachitika, mayikirowevu mabasi n'kumawotha mankhwala chifukwa avale thupi ndi kuichotsa a zanyengo pa nthawi.

Contact mafuta a zakudya m'magulu kusunthira chipangizo, Kuthetsa ake pa makoma zimachitika chifukwa alibe mkati ng'anjo pa ntchito ya kapu yoteteza kapena kugwiritsa ntchito chikhalidwe chake. Zimenezi zingachititse kuti mukufunika kukonza uvuni mayikirowevu ndi manja ake. Kuchotsa kapu ikhale mpaka kuwonongeka ake. Izi kupewa mavuto m'tsogolo.

chisamaliro chida

Pogwira malamulo a kusamalira mayikirowevu, mungathe kuchepetsa chiopsezo cha kulephera msanga wa luso:

• Muyenera powerenga malangizo Buku kwa Mlengi.
• Zamkatimu luso oyera adzakhala kwambiri kutalikitsa moyo wake. Kupukuta mayikirowevu ayenera kukhala pambuyo chilichonse kutentha chakudya chake.
• Ntchito kapu zoteteza ndi malo ake nthawi sadzagwiritsa kudzimvera kukonza uvuni mayikirowevu kwa nthawi yaitali kwambiri.
• Ngati kunyumba ndi ana, pali sayenera kuwerengedwa iwo njira.

Mu chochitika cha dzidzidzi kapena osakhala kugwilizana wa ntchito zida ananena malangizo kubwezeretsa ntchito za wothandizira khitchini, monga mayikirowevu lapansi. Kukonza manja ako adzakhala kuchepetsa ndalama njira.

Atazindikira chipangizo ndi mfundo za machitidwe a ng'anjo, kuchita mbali zawo m'malo silidzakhala Lofewa. Pogwira malamulo onse a ntchito mayikirowevu angakhale nthawi yayitali si kukumana ndi vuto njira kukonza anapereka.
