Ushajwa kanjani ilambu lokuqala

　I-flashlight ngokwayo isetshenziswa njalo ekuphileni kwethu kwansuku zonke, ikakhulukazi ukukhanya kwekhanda, okusetshenziselwa kakhulu izinhlelo zokusebenza eziningi. Iisibani sangaphambili esifakwe ekhandakulula ukuyisebenzisa futhi ikhulula izandla ukwenza izinto eziningi. Indlela yokushaja i-headlight, ngakho-ke sikhetha Uma uthenga isibani esihle, udinga ukukhetha imikhiqizo enezici ezihlukene ngokuvumelana nezikhathi zakho zokusebenzisa, ngakho-ke uyazi mayelana nezibani zangaphambili?

Ayini amalambu?

　　I-Headlamp, njengoba negama lisho, isibani esigqokwa ekhanda, okuyithuluzi lokukhanyisa lokukhulula izandla. Uma sihamba ebusuku, uma sibambe ithoshi, isandla esisodwa asikwazi ukukhululeka, ukuze singakwazi ukubhekana nezimo ezingalindelekile ngesikhathi. Ngakho-ke, ukukhanya okuhle okufanele sibe nakho lapho sihamba ebusuku. Ngendlela efanayo, lapho sikhempa ebusuku, ukugqoka izibani kungakhulula izandla zethu ukuze senze izinto ezengeziwe.

Ububanzi bokusetshenziswa kwezibani zangaphambili:

　　Imikhiqizo yangaphandle, efanelekile ezindaweni ezihlukahlukene. Kuyinto ebalulekile uma sihamba ebusuku futhi sikanise ngaphandle. Izibani zangaphambili zingase zibe usizo uma:

　　Ukuhamba ngezikebhe, izigxobo zokuhamba zisesandleni, ukucisha umlilo, ukuphenya emagumbini angaphansi, ukubuka ekujuleni kwenjini yakho yesithuthuthu, ukufunda etendeni lakho, ukuhlola imigede, ukuhamba ebusuku, ukugijima ebusuku, izibani zezimo eziphuthumayo. …..

Izinhlobo ezimbalwa zamabhethri ezivame ukusetshenziswa kumalambu angaphambili

　　1. Amabhethri ane-alkaline (amabhethri ane-alkali) amabhethri asetshenziswa kakhulu. Amandla ayo angaphezulu kwalawo amabhethri omthofu. Ayikwazi ukushajwa kabusha. Inamandla angu-10% kuya ku-20% kuphela ezingeni lokushisa eliphansi elingu-0F, futhi I-Voltage izokwehla kakhulu uma isetshenziswa.

　　2. Amabhethri e-nickel-cadmium (amabhethri e-Nickel-cadmium): angashajwa izikhathi eziyizinkulungwane, angakwazi ukugcina amandla athile, angeke aqhathaniswe namandla kagesi agcinwe kumabhethri e-alkaline, asenamandla angu-70% ezingeni lokushisa eliphansi. I-0F, i-rock climbing Kungcono ukuthwala ibhethri enamandla amakhulu phakathi nenqubo, ephakeme izikhathi ezi-2 kuya kwezi-3 kunebhethri evamile.

　　3. Ibhethri ye-lithium: Iphakeme izikhathi ezingu-2 kunomthamo webhethri evamile, futhi inani le-ampere lebhethri le-lithium lingaphezu kokuphindwe izikhathi ezingu-2 kunamabhethri amabili e-alkaline. Kufana nokusebenzisa ekamelweni lokushisa ku-0F, kodwa kubiza kakhulu, futhi i-voltage yayo ingagcinwa ingashintshi. Iwusizo ikakhulukazi ezindaweni eziphakeme.

Kunezinkomba ezintathu ezibalulekile zengaphandleprotableizibani zangaphambili:

　　1. Ukuvikela amanzi, akunakugwenywa ukuhlangana nezinsuku zemvula lapho ukhempa ngaphandle, uhamba ngezinyawo noma omunye umsebenzi wasebusuku, ngakho-ke izibani zangaphambili kufanele zingangeni manzi, ngaphandle kwalokho, uma lina noma licwiliswe emanzini, kuzokwenza isekethe emfushane futhi kubangele isekethe ukuthi ukuphuma noma ukucwayiza, okubangela izingozi zokuphepha ebumnyameni . Khona-ke, lapho uthenga izibani zangaphambili, kufanele ubone ukuthi lukhona yini uphawu olungangeni manzi, futhi kufanele libe likhulu kuneleveli elingangeni manzi le-IXP3 noma ngaphezulu. Uma inombolo iba nkulu, kuba ngcono ukusebenza kokuvikela amanzi (izinga elingangeni amanzi ngeke liphindwe lapha).

　　2. Ukumelana nokuwa.Isibani sangaphambili esisebenza kahlekufanele ibe nokumelana nokwehla (ukumelana nomthelela). Indlela yokuhlola evamile iwukuba uwe ngokukhululeka ukusuka ekuphakameni okungamamitha angu-2 ngaphandle kokulimala. Kungase futhi kubangelwe ukukugqoka ngokukhululeka kakhulu phakathi nemidlalo yangaphandle. Kunezizathu eziningi zokushelela, uma igobolondo liqhekeka, ibhethri liyawa noma isifunda sangaphakathi sihluleka ngenxa yokuwa, kuyinto esabekayo kakhulu ukuthola ibhethri eliwile ebumnyameni, ngakho-ke izibani ezinjalo aziphephile neze, ngakho-ke. kokuthi Lapho uthenga, kufanele futhi uhlole ukuthi lukhona yini uphawu oluvimbela ukuwa, noma ubuze umninisitolo mayelana nokusebenza okumelene nokuwa kwesibani sangaphambili.

　　3. Ukumelana nokubanda, ikakhulukazi imisebenzi yangaphandle ezindaweni ezisenyakatho nezindawo eziphakeme kakhulu, ikakhulukazi izibani zangaphambili ezinamabhokisi ebhethri ahlukanisiwe. Uma usebenzisa izintambo ze-PVC ezisezingeni eliphansi ukuze uthole izibani, kungenzeka ukuthi isikhumba sezintambo sizoba lukhuni ngenxa yamakhaza. Iba yi-brittle, okubangela ukuba i-wire core yangaphakathi iphuke, ngakho-ke uma ufuna ukusebenzisa ukukhanya kwangaphandle ekushiseni okuphansi, kufanele unake kakhulu ukwakheka komkhiqizo okumelana nokubanda.
