ibhethri ehlobo. Kungase kube nzima nalesi sikhathi sonyaka.
Sijwayele ukuthi izinkinga ngebhethri zenzeka ebusika, lapho umthamo webhethri wehla kakhulu ngenxa yesithwathwa. Yilapho-ke esivame ukuzwa ukuheleza kwabaqalayo futhi sibone imizamo yokuqala "ezintanjeni". Kodwa-ke, kufanelekile ukukhumbula ukuthi kungenzeka ukuthi ibhethri liyaphuma ngemva kwesikhathi eside sokupaka ngalesi sikhathi sonyaka. Kungani lokhu kwenzeka futhi kanjani ukubhekana nakho?
Ngaphambi kokuphendula lo mbuzo, kufanelekile ukunaka ukwakheka kwebhethri elisebenzisekayo nelingenakulungiswa. Ibhethri engu-12-volt esetshenziswa emotweni iwuhlobo lwe-galvanic cell engasetshenziswa kabusha futhi ishajwe kabusha ngogesi. Lonke ibhethri elisetshenziswa emotweni lakhiwe izingxenye ezifanayo, futhi izindlela zokukhiqiza kuphela ezisetshenziswayo kanye nobukhulu bazo obunquma ukubukeka kwebhethri, umthamo walo kanye nenjongo yemodeli yemoto ethile. Lawa mabhulokhi wokwakha afanayo yilawa:
- amaseli ayisithupha ahlukene, kodwa axhumene ane-voltage engu-2,1 V ngayinye;
- indlu, inhloso yokuqukatha amasethi amapuleti futhi inikeze ithuba lokufakwa unomphela emotweni;
- amaseli, i.e. isethi yamapuleti axhunyiwe amahle namabi ahlukaniswe ngabahlukanisi;
- abahlukanisi, i.e. izakhi ezivimbela ukuthintana phakathi kwamapuleti angalungile futhi alungile (ukuntuleka kwesihlukanisi kuzoholela ekuxhumaneni phakathi kwamapuleti, okuzoholela kumjikelezo omfushane);
- ama-gratings, i.e. izakhi ezisetshenziselwa kokubili amapuleti amahle kanye nama-negative, asebenza njengohlaka lwesakhiwo kanye nomqhubi wamanje kagesi;
- i-electrolyte, i.e. isisombululo se-sulfuric acid esibekwe endlini lapho kucwiliswa khona amapuleti amahle nebi. Umsebenzi wayo ukwenza kusebenze izinto ezisebenzayo zamapuleti futhi uqhube ugesi phakathi kwabo.
Bheka futhi: izincwadi zokushayela. Isigaba B kanye nokudonsa kwe-trailer
Ukusebenza kwebhethri eliyinhloko ukusabela kwamakhemikhali phakathi kwamapuleti acwiliswe ku-electrolyte ne-electrolyte, okuholela ekuqongeleleni noma ekukhishweni kwamashaji kagesi. Lapho i-current isethwe kabusha, i-electrolyte iyancibilika, ngoba, ukuyibeka ngokwemibandela nangokomfanekiso, i-sulfuric acid "ivuza" emapuletini. Uma ibhethri lishajwa, i-asidi "iphonswa" ku-electrolyte.
Bheka futhi: Ulinakekela kanjani ibhethri?
Ngakho-ke, i-electrolyte iyisici esisebenza njalo, futhi, ngaphezu kwalokho, ingaphansi kwezinto ezibonakalayo ezifana nokuhwamuka, futhi lokhu kuyisici esisebenzayo okufanele silawulwe.
Ezixazululweni zebhethri ezindala (izinketho zesevisi), kwakuyisiko ukwengeza i-electrolyte ngokuthela amanzi acwebile esitokisini ngasinye ngemuva kokukhulula amapulaki avala iseli. Amabhethri anganakekeli asetshenziswa kakhulu namuhla. Nokho, lokhu akusho ukuthi akunakwenzeka ukulawula futhi ngokunokwenzeka ukugcwalisa i-electrolyte. Nakuba bengenawo amapulaki avula ukufinyelela kumaseli, njengezinguqulo zesevisi, udinga ukususa ikhava ukuze wengeze uketshezi. Ngemva kokuyikhipha, siyakwazi ukufinyelela zonke iziteshi. Ukuze ugweme izenzo ezinjalo njalo, kukhona iso lesici ecaleni elibonisa isimo sokushaja kwebhethri. Umbala wendlebe kufanele uqhathaniswe nenganekwane, futhi uma ibhethri liphansi, ungaqala ukuhlola inani le-electrolyte nokushaja.
