Ukhetho olufanelekileyo lwe-screwdriver

Ngaphambi kokuba nabani abazimela ngokuzimeleyo indlu, igaraji, indawo yokuhlala ehlobo, kungekudala okanye kamva kukho ingxaki enjengokukhethwa kwe-screwdriver. Namhlanje, iimarike zinika ukhetho olukhulu lwezixhobo zombane ezingenakucala. Abanye bafaka umbhobho ukuba usebenze kunye nezikrini kwi-drill, kodwa oku akusoloko kulungele indawo, ngakumbi ukuba kufuneka usebenze yonke imihla yokusebenza. I-screwdriver engenasiphelo engenazintambo ineemisebenzi emininzi efunekayo, engenakutshintshwa nantoni na.

Ukuze ukhethe i-screwdriver ichanekile, kufuneka uqikelele imigaqo yayo. Into ebaluleke kakhulu kukuseka isantya sobuninzi bokusebenzisa isixhobo. Kubalulekile ukuqikelela, yiyiphi imisebenzi eya kwenziwa kwaye ziphindwe kangakanani ngosuku kusetyenziswe isixhobo ngaphandle kokuphazamiseka. Ukuba ubungqina bukufutshane nezobuchwephesha, ngoko kukhethwa kwe-screwdriver kufuneka kumiswe kwiitampu ezifana neBosh kunye neMakita.

Ziziphi iimpawu zesixhobo kufuneka uhlawule kuqala? Le mandla, amandla kunye nesantya. Inxalenye ephambili ye-screwdriver, evumela ukuba isebenze ngaphandle komthombo wamandla, ibhetri. Impawu zayo eziphambili ziyi-voltage kunye namandla, okokuqala kukulinganiswa kwi-volts (V), kwaye okwesibini ku-amperes / iyure (Ah). Isibonakaliso sombane sisisombululo sebhethri, kwaye amandla ke ixesha lokusebenza emva kokuhlawula. Ukusebenza kwexesha elide, iibhetri ezihlawulelwayo ezine- 1.3 Aphezulu kwaye ziphezulu, kunye negunya elivela kwi-12 V nangaphezulu lifanelekileyo. Thenga ngcono ezimbini ngexesha. Omnye usebenza kude ukhululeke ngokupheleleyo, omnye uhlawuliswe, kwaye kungcono ukuyihlawulisa ngokupheleleyo, kungekhona. Kule ndlela, iya kuhlala ixesha elide.

Ngokukhawuleza, kungcono ukuyeka ukukhethwa kwe-screwdriver kwi sixhobo sezantya ezimbini. Isivinini esiphantsi ngamandla amakhulu, njengomthetho, sisetyenziselwa inkqubo yokuguqula, kunye nesantya esiphezulu sokubumba.

Kwiimodeli ezingabizi kakhulu akukho iqhosha "lokuyeka". Kubiza kakhulu. Ukuba ucinezela, i-screwdriver iyayeka kwaye ayiyi kujikeleza, evumela ukuba utshintshe amabhulo. Ewe, ukuba unako ukuseta isigaba sokuqala. Oku kuya kuvumela i-screwdriver ukuba imise ngokuzenzekelayo kwaye ingaphambuki i-screws.

Xa ukhetha i-screwdriver yendlu, kufuneka uqiniseke ukuba iya kumelana nokuwa kwephakama ezimbini, kuba imodeli yanamhlanje inomda okwaneleyo wamandla. Ukunyamekela kwesi sixhobo kulula: kufuneka uhlambulule kwaye uhlambulule i-cartridge ngezikhathi ezithile, ugweme ingress of moisture, debris, isanti okanye uthuli. Kubalulekile ukuqinisekisa ukuba i-screwdriver ayithethi. Ukuba "akayi kutsala", kufuneka uyanciphise isantya okanye usebenzise ithuluzi elinamandla ngakumbi.

Ukukhethwa kwebhetriver yebhetri kubonisa ukukhetha uhlobo lwebhetri. Iimarike zinika i-NiMH (i-nickel-metal hydride) i-NiCd (i-nickel-cadmium), kunye ne-Li-Ion (i-lithium-ion).

I-NiCd inezinzuzo ezingenakuphika, kwaye zintathu zazo: ixabiso elincinci, inani elona liphezulu le-recharges, ngokulandelanayo, ixesha elide kakhulu lobungqina kunye nemali enkulu kakhulu ekhoyo yangoku. Ukungalungi "umphumo wokukhumbula", ukungaphumeleli ngokukhawuleza ukukhutshwa okungaphelelanga kunye nokuhlawula. Gcina ezi bhetri zicetyiswa kwifomu ekhutshwe ngaphandle kweqondo lokushisa. Ngakolunye uhlangothi, iinqununu ze-NiMH zicetyiswa ukuba zigcinwe kwimeko ehlawulweyo.

Ibhethri yeLi-Ion ine-disadvantage efana nokuguga, nangona ingasetyenziswa. Iminyaka emibini, ininzi yamandla ebhetri ilahlekile.

Namhlanje, kukho imizekelo yezihlaziyizi ezinokusebenza kwiintlobo ezahlukeneyo zeebhetri.

Into enobungozi kakhulu yile mveliso yeebhetri ze-nickel-cadmium. Kwintsimi ye-European Union, umveliso wabo awunqatshelwe. Olutsha olutsha kunye noluncinci kwaye lukhuselekile kwimo engummveliso, kwaye ke ukusetyenziswa kwamatribhethi e-nickel-metal hydride.
