Indlela yokubuyisela i-filaments yefasitela yangemuva evuthayo

Ukuqeda ngokushesha inkungu ye-windshield namafasitela angemuva, izintambo zensimbi ezisebenzayo zisetshenziswa kubo. Umsinga kagesi udlula kugridi eyakhiwe yibo, izintambo ziyashiswa, futhi i-condensate iyahwamuka. Ukushayela okunamaphutha kulolu hlelo kuyingozi, ukubonakala kuyancipha, futhi ukulungisa i-heater kulula kakhulu ezimweni eziningi.

Umgomo wokusebenza kwefasitela elingemuva elishisayo

Lapho i-current idlula ezinsimbi, amandla ama-electron aguqulwa abe ukushisa. Izinga lokushisa lama-conductor likhuphuka ngokulingana nesikwele samandla amanje kanye nokumelana nogesi.

Ingxenye yesiphambano se-filaments ibalwa ngendlela yokuthi inikeze amandla anele okushisa kubo nge-voltage esetshenzisiwe elinganiselwe. Kusetshenziswa inani elijwayelekile elingamavolthi angu-12 wenethiwekhi esebhodini.

I-Voltage ihlinzekwa ngesekhethi ehlanganisa i-fuse evikelayo, i-relay yamandla kanye neswishi elawula ukujika kwayo.

I-current ebalulekile igeleza koxhumene nabo, kusukela kuma-ampere ayishumi nambili noma ngaphezulu, kuya ngendawo yokucwebezela kanye nokusebenza kahle okulindelekile, okungukuthi, ijubane lokuhlanza indawo enenkungu kanye nezinga lokushisa lengilazi kanye umoya.

I-current isakazwa ngokulinganayo phezu kwemicu, eyenziwa ngayo ngokunembe ngangokunokwenzeka, ngesigaba esinqunyiwe esinqunyiwe.

Kungani izinto zokushisisa zihluleka?

Ikhefu lingenzeka ngenxa yezizathu zemishini noma zikagesi:

• insimbi yentambo kancane kancane i-oxidizes, ingxenye yesiphambano iyancipha, futhi amandla akhululiwe akhula, ukushisa okunamandla kubangela ukuba intambo iqhume futhi ukuthintana kunyamalale;
• lapho uhlanza ingilazi, umugqa omncane wensimbi efafaziwe wonakaliswa kalula ngemiphumela efanayo;
• ngisho nokukhubazeka okuncane okushisayo kuholela ekwehleni kwesakhiwo se-strip conductive, esiphetha ngokubonakala kwe-microcrack nokulahlekelwa kokuxhumana kukagesi.

Ezikhathini eziningi, kugqashuka umucu owodwa noma ngaphezulu, futhi yonke inetha akuvamile ukuba ihluleke ngokuphelele. Lokhu ngokuvamile kungenzeka ngenxa yokwehluleka kwamandla, i-fuse evutheliwe, i-relay noma ukwehluleka kokushintsha.

Ngezinye izikhathi ukushintsha kuyinkimbinkimbi ngokwethulwa kokudluliselwa kwe-elekthronikhi okuzenzakalelayo ngokuvalwa kwe-timer, okungafaki ukwethembeka.

Indlela yokuthola ikhefu ku-filaments yokushisa ingilazi

Ukufinyelela emicu ye-conductive efasiteleni elingemuva kulula, ngakho-ke ungasebenzisa i-multimeter evamile, kuhlanganise ne-ohmmeter ne-voltmeter, ukuxazulula inkinga. Zombili izindlela zifanelekile.

Ukuhlola okubonakalayo

Esimeni sokwephulwa okukhulu kobuqotho, ukulawulwa kwezinsimbi kungase kungadingeki, ukuphuka noma ukunyamalala kwengxenye yonke yomugqa kubonakala emehlweni. Kungcono ukuhlola lokho okutholwe ngengilazi yokukhulisa, ngaphansi kwayo ukukhubazeka kubonakala kuyo yonke imininingwane.

Ukwenziwa kwasendaweni okuyinhloko kokungasebenzi kahle kubonakala ngokushesha lapho ukushisisa kuvuliwe engilazini enenkungu. Izinhlayiya eziphelele ngokushesha zakha izingxenye zengilazi ezisobala zizizungezile, futhi i-condensate ihlala isikhathi eside eduze komcu odabukile.

Ihlola imicu nge-multimeter

Ungakwazi ukuhambisana nomugqa oboniwe onephutha ngophenyo olucijile lwedivayisi ngemodi ye-voltmeter noma ye-ohmmeter.

Imodi ye-Ohmmeter

Lapho uhlola indawo esolisayo, i-multimeter ishintshela kumodi yokulinganisa ukuphikiswa okuncane kakhulu. Uchungechunge olusebenzayo lunikeza izinkomba zokuphikiswa okuncane, okucishe kube ziro. Okulengayo kuzobonisa ukumelana kwayo yonke igridi, okuphawuleka kakhulu.

Ngokuhambisa ama-probe eduze kwayo, ungathola indawo lapho ukufundwa kwedivayisi kwehlela kuqanda kungazero. Lokhu kusho ukuthi iwa selidlulile, kufanele sibuye, sicacise indawo yewa, futhi siyihlole ngengilazi yokukhulisa. Isici sinqunywa ngokubukeka.

Uma usebenza nge-ohmmeter, qiniseka ukuthi ucisha ukushisa nokushisa. Kungcono nakakhulu ukususa isixhumi sokushisa engilazini.

Imodi ye-Voltmeter

I-voltmeter, ama-probes atholakala ebangeni elincane eduze komugqa osebenzisekayo, ikhombisa i-voltage encane, cishe ngokulingana nebanga eliphakathi kwabo. Ebangeni eliphakeme kakhulu, lapho uxhunywe emaphethelweni egridi, idivayisi izobonisa i-voltage ye-mains, cishe i-volts engu-12.

Uma ukuhlangana kwama-probe emgqeni owodwa kungaholeli ekwehleni kwe-voltage, khona-ke kulo mdwebo lapho kukhona ikhefu. Ngemuva kokudlula kuyo, ukufundwa kwe-voltmeter kuzokwehla ngokuzumayo.

Umgomo uyafana ne-ohmmeter. Umehluko wukuthi isici siseshwa nge-voltmeter lapho ukushisa kuvuliwe, futhi nge-ohmmeter, ivaliwe.

Zenzele wena ukulungisa ukushisa kwefasitela elingemuva

Ukushintsha ingilazi eshisayo kubiza kakhulu. Phakathi naleso sikhathi, imichilo edabukile ingalungiswa, lapho kuthengiswa khona ukwakheka okuhambisanayo namakhithi.

Ithrekhi enamathelayo

Ukuze kulungiswe nge-gluing, i-adhesive ekhethekile kagesi isetshenziswa. Iqukethe i-binder kanye nempushana yensimbi enhle noma ama-chips amancane. Uma kusetshenziswe ithrekhi, othintana naye uyabuyiselwa.

Kubalulekile ukugcina izici zokumelana komugqa wentambo (i-strip). Ukuze wenze lokhu, ingilazi inamathiselwe nge-masking tape, phakathi kwamapheshana okukhona ibanga elilingana nobubanzi bentambo ebuyiselwe. Ukumelana komqhubi kuncike kububanzi nobukhulu bayo. Ngakho-ke, kusala ukunikeza isendlalelo sokulungisa ukuphakama okufunayo okuhlobene nengilazi.

Ulwazi oludingekayo ngenani lezendlalelo zohlelo lokusebenza lunqunywa ukuminyana kwe-adhesive ethile yezohwebo futhi kuboniswe kulebula. Bonke ubuchwepheshe bokukhanda buchazwe lapho.

Ngemuva kokuthi ungqimba lokugcina lomile, i-adhesive eduze ne-adhesive tape kufanele inqunywe ngommese womfundisi ukuze lapho ususa isivikelo, isitika sonke asiqediwe ingilazi. Indawo elungisiwe ibhekwa ngokubukeka, ngezinga lokukhishwa kwe-condensate noma ngomshini, kusetshenziswa izindlela ezikhonjiswe ngenhla.

I-Copper Plating

Kukhona indlela yokusebenzisa ungqimba oluncane lwensimbi endaweni yekhefu ngendlela ye-electrochemical. Kunzima impela, kepha kungabizi kakhulu kubalandeli be-electroplating. Uzodinga ama-reagents - i-copper sulfate kanye nesisombululo esibuthakathaka se-sulfuric acid, hhayi ngaphezu kwe-1%.

1. Kwenziwa ibhulashi elinothayela. Lena inqwaba yezintambo ezinemicu yengxenye encane yochungechunge ngalunye. Ziboshelwe ngaphakathi kweshubhu lensimbi elincanyana.
2. Indawo yokulungisa inamathiselwe phezu kwe-tape kagesi, kukhona igebe lobubanzi be-strip. Imeshi igxile emzimbeni wemoto, futhi ibhulashi lixhunywe kutheminali ephozithivu yebhethri ngelambu lokukhanyisa elivela ekukhanyeni kwangaphandle kwemoto.
3. Ukulungiselela isisombululo se-galvanic ku-100 ml wamanzi, amagremu ambalwa we-vitriol nesisombululo sebhethri sulfuric acid yengezwa. Ukumanzisa ibhulashi, balihola kusukela ekuqaleni komugqa osetshenziswayo ukuya endaweni yekhefu, kancane kancane befaka ithusi engilazini.
4. Emizuzwini embalwa kamuva, kuvela indawo egqitshwe ngethusi, evala indawo yewa. Kudingeka ukufeza cishe ukuminyana kwensimbi okufanayo naleyo ye-mesh yasekuqaleni.

Uma amakhithi okulungisa etholakala ukuze athengiswe, indlela ayifanele kakhulu, kodwa isebenza kahle kakhulu. Umqhubi ozovela ngemva kokuqeqeshwa okuthile ngeke abe mubi kunomusha.

Kukuziphi izimo akusizi ukulungisa izinto zokushisa

Ngendawo enkulu yomonakalo, lapho cishe zonke izintambo ziphukile futhi ngaphezu kwendawo enkulu, akunakwenzeka ukuthi igridi ingabuyiselwa ekusebenzeni okujwayelekile. Asikho isidingo sokuthembela ekuthembekeni komphumela. Ingilazi enjalo kufanele ishintshwe iphelele ngesici sokushisa.

Ezimweni ezimbi kakhulu, ungasebenzisa i-heater yangaphandle efakwe ngaphansi kwengilazi, kodwa lokhu kuyisilinganiso sesikhashana, sisebenza kancane, ngokungalingani, sisebenzisa amandla amaningi, futhi uma ingilazi iqhwa kakhulu, ingabangela ukuqhekeka ngisho nokuchitheka. ingilazi epholile.
