Kodi kubwezeretsa mkangano kumbuyo zenera filaments

Kuti athetse msanga chifunga cha windshield ndi mazenera akumbuyo, ulusi wachitsulo wothandizira umagwiritsidwa ntchito kwa iwo. Mphamvu yamagetsi imadutsa mu gridi yopangidwa ndi iwo, ulusi umatenthedwa, ndipo condensate imasanduka nthunzi. Kuyendetsa ndi zolakwika m'dongosolo lino ndikoopsa, kuwonekera kumachepetsedwa, ndipo kukonza chowotcha kumakhala kosavuta nthawi zambiri.

Mfundo ya ntchito ya mkangano kumbuyo zenera

Pamene panopa akudutsa muzitsulo, mphamvu ya ma elekitironi imasandulika kutentha. Kutentha kwa ma conductors kumawonjezeka molingana ndi lalikulu la mphamvu zamakono ndi kukana magetsi.

Gawo la mtanda la filaments limawerengedwa m'njira yoti apereke mphamvu zokwanira zotentha kwa iwo ndi magetsi ochepa omwe amagwiritsidwa ntchito. Mtengo wokhazikika wa pafupifupi 12 volts wa netiweki yapa board imagwiritsidwa ntchito.

Voltage imaperekedwa kudzera mu dera lomwe limaphatikizapo fuse yoteteza, relay yamagetsi ndi chosinthira chomwe chimawongolera mafunde ake.

Kuthamanga kwakukulu kumadutsa pazitsulo zolumikizirana, kuyambira khumi ndi awiri amperes kapena kupitirira, kutengera dera la glazing ndi momwe akuyembekezeredwa, ndiko kuti, kuthamanga kwa kuyeretsa pamwamba pa chifunga ndi kutentha kwa galasi ndi mpweya.

Zamakono zimagawidwa mofanana pa ulusi, zomwe zimachitidwa molondola momwe zingathere, ndi gawo la mtanda.

Chifukwa chiyani zinthu zotenthetsera zimalephera?

Kupuma kumatha kuchitika pazifukwa zamakina kapena zamagetsi:

• chitsulo cha filament pang'onopang'ono chimakhala ndi oxidized, gawo la mtanda limachepa, ndipo mphamvu yotulutsidwa imawonjezeka, kutentha kwamphamvu kumapangitsa kuti filament isungunuke ndipo kukhudzana kutha;
• poyeretsa galasi, chitsulo chopyapyala chopopera chimawonongeka mosavuta ndi zotsatira zomwezo;
• ngakhale pang'ono matenthedwe mapindikidwe kumabweretsa kufooka kwa kapangidwe ka conductive Mzere, umene umatha ndi maonekedwe a microcrack ndi kutaya magetsi kukhudzana.

Nthawi zambiri, ulusi umodzi kapena zingapo zimaduka, ndipo mauna onse salephera kwathunthu. Izi zitha kuchitika chifukwa cha kulephera kwamagetsi, kuwomberedwa kwa fuse, relay kapena kulephera kwa switch.

Nthawi zina kusintha kumakhala kovutirapo chifukwa chokhazikitsa cholumikizira chamagetsi chodziwikiratu ndi kutseka kwa timer, komwe sikumawonjezera kudalirika.

Kodi kupeza yopuma galasi Kutentha filaments

Kufikira zopangira zopangira pazenera lakumbuyo ndikosavuta, kotero mutha kugwiritsa ntchito ma multimeter wamba, kuphatikiza ohmmeter ndi voltmeter, kuthana ndi mavuto. Njira zonsezi ndi zoyenera.

Kuwona zowoneka

Pakakhala kuphwanya kwakukulu kwa kukhulupirika, kuwongolera zida sikungakhale kofunikira, kusweka kapena kutha kwa gawo lonse la mzerewu kumawonekera m'maso. Ndi bwino kuyang'ana zomwe zinapezeka ndi galasi lokulitsa, pansi pake cholakwikacho chikuwonekera mwatsatanetsatane.

Kukhazikika koyambirira kwa vutolo kumawonekera nthawi yomweyo pomwe kutentha kumayatsidwa pagalasi lopanda kanthu. Ulusi wathunthu umapanga magalasi oonekera mwachangu, ndipo condensate imakhala kwa nthawi yayitali kuzungulira ulusi wong'ambika.

Kuwona ulusi ndi multimeter

Mutha kupita pamzere wolakwika womwe mwawona ndi chowunikira cha chipangizocho mu voltmeter kapena ohmmeter mode.

Ommeter mode

Mukayang'ana malo okayikitsa, ma multimeter amasintha kupita kunjira yoyezera kukana kocheperako. Ulusi wogwira ntchito umapereka ziwonetsero zazing'ono, pafupifupi kukana zero. Cholendeweracho chidzawonetsa kukana kwa gridi yonse, yomwe imakhala yayikulu kwambiri.

Mwa kusuntha ma probes motsatira, mutha kupeza malo omwe kuwerengera kwa chipangizocho kumatsikira ku ziro. Izi zikutanthauza kuti thanthwelo ladutsa, tiyenera kubwerera, kulongosola malo a thanthwelo, ndi kulipenda kupyolera mu galasi lokulitsa. Chilemacho chimatsimikiziridwa ndi mawonekedwe.

Mukamagwira ntchito ndi ohmmeter, onetsetsani kuti muzimitsa kuyatsa ndi kutentha. Ndikwabwinonso kuchotsa cholumikizira chotenthetsera pagalasi.

Voltmeter mode

Voltmeter, ma probes omwe ali patali pang'ono ndi chingwe chothandizira, akuwonetsa magetsi ang'onoang'ono, pafupifupi molingana ndi mtunda wapakati pawo. Pamtunda wautali, mukalumikizidwa m'mphepete mwa gridi, chipangizocho chidzawonetsa magetsi a mains, pafupifupi 12 volts.

Ngati kuphatikizika kwa ma probes pamzere umodzi sikupangitsa kuchepa kwa voliyumu, ndiye kuti mumzerewu muli kupuma. Pambuyo podutsa, zowerengera za voltmeter zidzatsika mwadzidzidzi.

Mfundoyi ndi yofanana ndi ohmmeter. Kusiyanitsa ndiko kuti chilema chimafufuzidwa ndi voltmeter pamene kutentha kumatsegulidwa, ndipo ndi ohmmeter, imatsekedwa.

Dzichitireni nokha kukonza zotenthetsera zenera lakumbuyo

Kusintha magalasi otenthetsera ndikokwera mtengo kwambiri. Pakadali pano, zingwe zong'ambika zimatha kukonzedwa, zomwe zofananira ndi zida zimagulitsidwa.

Njira yomatira

Pakukonza ndi gluing, zomatira zapadera zamagetsi zimagwiritsidwa ntchito. Lili ndi binder ndi ufa wabwino wachitsulo kapena tchipisi tating'ono. Mukagwiritsidwa ntchito panjanji, kukhudzana kumabwezeretsedwa.

Ndikofunika kusunga mawonekedwe a kukana kwa mzere wa ulusi (mzere). Kuti muchite izi, galasi imayikidwa ndi masking tepi, pakati pa mizere yomwe pali mtunda wofanana ndi m'lifupi mwa ulusi wobwezeretsedwa. Kukaniza kwa conductor kumadalira m'lifupi mwake ndi makulidwe ake. Chifukwa chake, zimatsalira kuti zipatse wosanjikiza wokonza kutalika kofunikira poyerekeza ndi galasi.

Zomwe zimafunikira pa chiwerengero cha zigawo zogwiritsira ntchito zimatsimikiziridwa ndi kachulukidwe ka zomatira zinazake zamalonda ndipo zikuwonetsedwa pa chizindikiro. Tekinoloje yonse yokonzanso ikufotokozedwanso pamenepo.

Mukamaliza kuyanika kwa gawo lomaliza, zomatira pafupi ndi tepi yomatira ziyenera kudulidwa ndi mpeni waunsembe kuti pakuchotsa chitetezo, chomata chonsecho sichimang'ambika pagalasi. Malo okonzedwawo amafufuzidwa mowonekera, ndi mlingo wa kuchotsa condensate kapena ndi chipangizo, pogwiritsa ntchito njira zomwe zasonyezedwa pamwambapa.

Copper plating

Pali njira yogwiritsira ntchito chitsulo chochepa kwambiri chachitsulo kumalo opuma ndi electrochemical njira. Ndizovuta, koma zotsika mtengo kwa mafani a electroplating. Mudzafunika ma reagents - mkuwa sulphate ndi njira yofooka ya sulfuric acid, osapitirira 1%.

1. Burashi yamalata ikupangidwa. Ili ndi mtolo wa mawaya omangika a gawo laling'ono kwambiri la ulusi uliwonse. Iwo ali crimped mkati mwa chubu woonda zitsulo.
2. Malo okonzerawo amaikidwa ndi tepi yamagetsi, pali kusiyana kwa m'lifupi mwake. Ma mesh amakhazikika ku thupi lagalimoto, ndipo burashi imalumikizidwa ku terminal yabwino ya batire kudzera pa babu kuchokera pakuwunikira kwakunja kwagalimoto.
3. Kukonzekera yankho la galvanic kwa 100 ml ya madzi, magalamu angapo a vitriol ndi yankho la batri sulfuric acid amawonjezeredwa. Kunyowetsa burashi, amatsogolera kuyambira pachiyambi cha chingwe chothandizira kupita kumalo opuma, pang'onopang'ono kuika mkuwa pagalasi.
4. Mphindi zochepa pambuyo pake, malo opangidwa ndi mkuwa akuwonekera, akuphimba malo a thanthwelo. Ndikofunikira kuti mukwaniritse pafupifupi kachulukidwe kachitsulo kofanana ndi kaukonde koyambirira.

Ngati zida zokonzera zilipo zogulitsa, njirayo siili yofunikira kwambiri, koma ndiyothandiza kwambiri. Wotsogolera wotsatira pambuyo pa maphunziro sadzakhala woipa kuposa watsopano.

Pazifukwa ziti ndi zopanda pake kukonza zinthu zotentha

Ndi dera lalikulu la zowonongeka, pamene pafupifupi ulusi wonse wathyoledwa ndi kudera lalikulu, sizingatheke kuti gululi libwezeretsedwe kuti likhalenso bwino. Palibe chifukwa chodalira kudalirika kwa zotsatira. Galasi yotereyi iyenera kusinthidwa ndi chinthu chotenthetsera.

Zikavuta kwambiri, mutha kugwiritsa ntchito chotenthetsera chakunja chomwe chimayikidwa pansi pagalasi, koma iyi ndi muyeso kwakanthawi, imagwira ntchito pang'onopang'ono, mosagwirizana, imawononga mphamvu zambiri, ndipo ngati galasi lazizira kwambiri, lingayambitse ming'alu komanso kutayika kwa madzi. galasi lotentha.
