I-Screwdriver iyithuluzi elihlanganayo lanoma yimuphi umcebo onolwazi. Ngakho-ke, kuyadingeka ukusondela ekukhetheni kwakhe ngokucophelela. Emakethe yanamuhla kunezinhlobo eziningi ezahlukahlukene zezikulufu zikagesi ezenzelwe imisebenzi ehlukene.
Uhlelo lwedivayisi ye-screwdriver.
Ukukhetha i-screwdriver yobungcweti ukuze uzikhethele, unqume ukuthi umsebenzi wakho uzophethwa uthini. Kuyadingeka ukuze kungasebenzi ukuze ithuluzi lithengwe ngemali enkulu, liyasetshenziswa futhi manje amanga futhi alisasenakudingeka epulazini.
Ukuze ukhethe kahle isikulufa esiqeqeshiwe ngokwakho, udinga ukugxila kumapharamitha ayisisekelo amaningana. Kudla, ijubane kanye ne-torque, i-cartridge acintwe, ukubuyela emuva kanye nezici ezingeziwe. Cabanga ngakho konke lokhu ngemininingwane eminingi.
Izici zemithombo yamandla
Inkomba eyinhloko yokulungiswa kwethuluzi ngumthombo wamandla. Njengomthetho, ngaphambi kokuba izikulufa zithathwe ukuhlukanisa kumadivayisi wohlobo lwebhethri futhi zisebenza kuphela kunethiwekhi. Kepha manje yonke i-screwdrivers kagesi inebhethri lezinhlobo ezithile. Ngakho-ke, kunengqondo ukuhlukanisa ithuluzi kwimithombo yamandla.
Izinhlobo zama-nozzles ze-screwdriver.
Okokuqala, udinga ukubheka ipulaki. Okuhle kakhulu - kwehla. Inzuzo yabo ukuthi lapho ukwephuka, kungakhuthazwa futhi kulungiswe. Ipulaki eliqinile uma kwenzeka kungasebenzi kahle kuzodinga ukushintshwa okuphelele ngentambo.
Isici sesibili esibalulekile somthombo wamandla uhlobo lwebhethri. Ngisho nenethiwekhi yokusebenza i-screwdriver isebenzisa ukushaja kwebhethri. Manje kunezinhlobo ezintathu zamabhethri ahluke emandleni nokuphepha kwawo kwemvelo.
Ngakho-ke, uhlobo lwebhethri le-lithium-ion lubhekwa njengelinamandla kakhulu kwisikulufa. Ngenxa yalokhu, kuhluka kakhulu izindleko eziphakeme kakhulu. Amabhethri anjalo asaphatha ngokuphelele kabusha futhi ayakwazi ukugcina ukushaja isikhathi eside. Impahla eyinhloko ukuntuleka kwenkumbulo. Noma ngokufika okungaphelele kwebhethri, ungakubeka kalula ekuvuseleleni kabusha. Kulokhu, isitsha ngeke sinciphe.

Kodwa-ke, kukhona lapha kanye ne-Cons. Isibonelo, amabhethri alolu hlobo aphatha kabi ukungafani kokushisa okubukhali. Ngaphezu kwalokho, amakhaza awalungile. Ngakho-ke, ukusebenzisa i-screwdriver enjalo ngaphansi kwezimo ezibandayo ezingathandeki. Futhi umphumela wokuzidweba kumabhethri ubuthakathaka impela.
Uhlobo lwesibili lwamabhethri luyi-nickel. Banokungezwa kwama-metal hydrides, noma i-cadmium. Akukho mehluko phakathi kwabo. Kepha amabhethri ohlobo lwe-lithium-ion ahluka kakhulu. Lawa mabhethri anamandla aphansi, abe nomphumela wememori, okwenza ukuthi khipha ithuluzi ngokugcwele kuze kube yilapho eqala kabusha.

Kumele kwaziwe ukuthi la mabhethri ayingozi kakhulu kumagama wezemvelo, njengoba aqukethe izinto ezinobuthi obunamandla. Ngakho-ke, ukusebenzisa i-screwdriver enebhethri yalolu hlobo empilweni yansuku zonke, kuyadingeka ngokucophelela kakhulu. Ngesizathu esifanayo, akunakwenzeka ukulahla amabhethri ozinzile noma ama-screwfrivers alolu hlobo.
Kepha bane-pluses bayamelana nokushintshwa kokushisa, ukubekezelela isithwathwa esibi kakhulu ngaphandle kokulimaza izici zethuluzi, kanye nentengo ephansi. Ngenxa yenani le-screwdrivers ngamabhethri anjalo, okuningi kungena emakethe kunasemabhethri e-lithium-ion.
Ukukhetha umvikeli omuhle
Isici esilandelayo uhlobo lwe-cartridge. Njengomthetho, noma ngabe ukhiye noma ohlolwe ngokusheshayo ama-cartridge athathwa ngama-screwdrivers. I-cartridge esheshayo yenza ukuthi kwenzeke ukuthi sibambezele ukumba ngokushesha ngaphandle kokusebenzisa ukhiye okhethekile. Kuhle ukonga isikhathi, kepha kubi ngakolunye uhlangothi, ngoba kungenzeka ukusuka ku-drill. I-cartridge ingaba ne-clutch eyodwa yokulungisa noma ezimbili. Vele, kungcono ukuthenga i-cartridge bimiftt.Ama-cartridge abalulekile ayindlela lapho ukushayela kulungiswe khona ngokuguqula ukhiye okhethekile. Ngenxa yalokho, ungathinta ngisho nobunzima bokukhamba. Ngenxa yalokho, ukuthembeka kwentaba kuphakama kaningana.
Ngakho-ke, kungaphethwa ngokuthi kungcono ukukhetha ama-cartridge anesihluthulelo uma uhlose ukusebenzisa i-screwdriver njalo futhi awunalo umugqa wokushintsha umgexo. Ama-cartridges anamathegi anesizathu lapho udinga ukushintsha ukumba amahlandla amaningi. Ngasikhathi sinye, umsebenzi owenziwa yithuluzi awumeleli ubunzima obukhethekile.

Isivinini sokujikeleza kanye ne-torque
Ithebula lezimpawu eziphambili ze-screwdrics.
Inkomba ebaluleke kakhulu ijubane eliphezulu lokujikeleza kwe-nozzle yomsebenzi. Ngokuya ngejubane, ukusonteka noma ukukhombisa izikulufo ongakwenza esikhathini esithile sesikhathi. Ngokuvumelana nalokhu, lapho umsebenzi uzoba ngokushesha, futhi okuphambene nalokho.
Kubalulekile ukwazi ukuthi i-screwdriver izosetshenziswa kanjani. Uma lokhu kusebenza kuphela ngezikulufo, khona-ke kuzoba nezinguquko ezingama-500 ngomzuzu. Kepha uma kuthathwa futhi ukuthi kudliwe okuthile, khona-ke ijubane ngokwesilinganiso akufanele kube ngaphansi kokuvukelwa okungu-1000.
Izikulufu zesimanje zifakwe ama-relgulators akhethekile efindo, lapho ungaguqula khona ngokuzimela ijubane lokujikeleza. Ngakho-ke, kubalulekile ukuba nomlawuli onjalo. Ngemuva kwakho konke, ngisho nangomsebenzi ojwayelekile ngezikulufo, abantu munye zizoba lula ukusebenza ngejubane eliphansi, kanti ezinye ziphezulu.
I-torque ephezulu enye inkomba enkulu. Inquma amandla ento yokujikeleza emzimbeni, lapho kwenziwa khona umsebenzi. Le yinkomba ebucayi ngokwengeziwe, ngoba kuzoncika kulo mzuzu amandla okusebenza nosayizi othile ngezikulufo.
Idivaysi ye-tripculalatory cartrid.
Njengomthetho, izikulufu eziqeqeshiwe zine-torque ecishe ibe ngu-10 n / m. Kepha izinsimbi zasendlini nazo zingaba nephuzu elicishe libe ngu-15-30 n / m. Lokho wukuthi, esimweni sokuqala, ungasebenza ngokukhululeka ngisho nangezikulufo ezinkulu kakhulu nezikhulu, futhi ngamandla wesibili kuzoba nesibalo esanele kwizikulungwane ezijwayelekile eziphakathi nendawo.
Kubaluleke kakhulu ukuthi i-screwdriver yayinomunye umlawuli, ozonquma amandla e-torque. Lokhu ngeke kuncike hhayi kuphela ukusebenza kokusebenza ngosayizi othile we-fastener, kepha futhi kube lula okuhlanekezela ezintweni zombumbi ezahlukene. Futhi, ukusebenza ngezizathu eziqinile udinga ukukhetha i-torque enkulu.

Buyela emuva nezinye izici ezengeziwe
Enye ingxenye ebalulekile ye-screwdriver iyahlehlisa emuva. Babizwa ngokuthi amathuba okujikeleza i-cartridge eyinhloko eqonde ngaphesheya. Vele, lesi sici kufanele sibe luhlanganiswe nganoma yiluphi uhlobo lwe-screwdriver. Kepha naphezu kwalokhu, akuwona wonke amathuluzi anempahla enjalo okubalulekile ukunaka lapho ukhetha.
I-screwdriver enhle kagesi ayifaki kuphela umsebenzi wokubuyela emuva - kusekhona switch ekhethekile, okuvumela ukuthi uvimbe inkinobho yokushintsha ngakolunye uhlangothi. Futhi lokhu kubaluleke kakhulu, kusukela lapho kusebenza inkinobho kungahle kube khona ngengozi, okuholele esikuluyeni, nokushayela, futhi isisekelo sonakaliswe.
Futhi kukhona ukubuka okufushane kwezinye izici ezengeziwe. Lokhu kufaka phakathi ukukhanya, ukukhiya i-spindle (bekuvele kunenkulumo ngenhla, kunesimo esiphezulu sokubuyiselwa emuva), kanye nezici zangaphandle zethuluzi. Njengomthetho, umsebenzi wokubuyela emuva kwesinye isikhathi ubalwa ukuze ungeziwe.
Ngokuqondene nokukhanya okukhangayo, ezinye izikulufu ezisezingeni eliphakeme zihlome ngethoshi elincane, kodwa elinamandla impela, lapho kungenzeka ukuthi lusebenze khona ngisho nasebumnyameni. Lokhu kungumsebenzi obalulekile kochwepheshe umsebenzi wabo ohlotshaniswa nokusetshenziswa okuqhubekayo kwe-screwdriver ezimweni ezingezona ezijwayelekile.
Ngokuqondene nezimpawu zangaphandle, ama-screwdrivers anendlela ehlukile yesibambo. Ngakho-ke, kunamathuluzi aklanyelwe umsebenzi kuphela lapho ebambe endaweni evundlile noma mpo. Lokhu akusho ukuthi kwesinye isikhundla akunakwenzeka ukusebenza. Vele ukwenze nje kukhululeke kangako. Futhi kukhona nezikulufu lapho kufanele khona ukusebenza kuzo njalo. Njengomthetho, banesibambo esiguqukayo.
Ngakho-ke, amaphuzu avelele adinga ukubhekwa ukukhetha i-screwdriver yemisebenzi ehlukene abhekwa ngokuphelele.
Ukubalwa kwezimpawu zazo zonke izici ezingenhla kuzokutshela ukuthi ungalikhetha kanjani ithuluzi elifanele, ngenkathi ungasebenzisi imali engaphezu kwesidingo, imali.
