Ishaja ye-screwdriver - indlela yokwenza ukukhetha

Indlela ukukhetha ishaja esifanele ukufakwa kokumqoka kuphela? Nge lo mbuzo ezibhekene bonke abadinga ukuthenga imishini. Kodwa akunzima kangako, zikhona imithetho embalwa, ezilandelayo, kungenzeka ukuthola eliphezulu futhi ishaja eliqinisekile lesikhathi screwdriver.

izibalo

Uma sibheka izibalo, ukuthandwa sokuzivivinya isikudilayiva anda ikakhulukazi ngenxa kungenzeka ngokusebenzisa isikhathi eside impela ibanga kude umthombo wamandla, njengoba anemisila amabhethri, ngakho-ke, umsebenzi kungaba kwenziwe ngisho endaweni zinomswakama. Ngakho-ke, lezi zikhathi zokuzivivinya bengafani ukuhamba kwakhe evamile. abakhiqizi eziholela ezifana Makita, Metabo, Bosch, Black Decker, Hitachi amathuluzi amandla asetshenziswa amabhethri abo zinhlobo ezifana:

1. NiMH.
2. Lithium-ion.
3. Nickel-cadmium amabhethri.

Izinzuzo nezingozi nebubi

amadivaysi Nickel-cadmium - ethandwa kakhulu, onobuhle abaziwayo - Bosch 12 futhi Hitachi DS. Okunjalo amashaja ngoba isikudilayiva ibe nenani eliphansi, kuqhathaniswa ngokushesha icala nokugcina umthamo high in the izimo ezingezinhle kakhulu, ngisho noma izinga lokushisa lingaphansi degrees amabili ngaphansi kwezingaqhwa. I ethile kuphela - kuba ukulahlekelwa unproven besikhundla ibhethri icala lapho lingatshajwa.

isicelo

Ishaja ye-NiMH ungenantambo ukufakwa kokumqoka kuphela isetshenziswa ukusetha DS 18 umakhi Hitachi. Kuyinto imvelo inguqulo yangaphambilini, kanye intengo kancane ezibizayo, kodwa amandla likhulu kakhulu amandla kwabantu kunakunoma nickel-cadmium, amaphesenti amane ngokwengxenye iqedwe umphumela ukukhohlwa. Self-osenyameni Ni-MH amadivayisi ephakeme engxenyeni.

imikhiqizo emisha emsebenzini wokukhiqiza ibhethri amashaja

Ukuthuthukiswa yamuva emkhakheni abakhiqizi amathuluzi amandla kuyinto lithium-ion battery ishaja ngokuba screwdriver accumulator. Idivayisi kungekho ukulahlekelwa inkumbulo, ngakho icala, kungakhathaliseki isikhundla, zingenziwa nganoma yisiphi isikhathi, amandla webhethri kuphezulu, kuphela ezinhlanu angu-self-osenyameni ngenyanga.

accumulator umthamo

umthamo webhethri ulinganiswa ampere-amahora. Ibhethri kuwo kakhudlwana isikhathi eside idivayisi sizosebenza okukodwa ngaphansi kwezimo ezifanayo. Uma umthamo mkhulu, futhi wamanje esiphezulu kuyinto ephakeme, kusho ukuthi amandla kunamandla. Likhono amamodeli elisetshenziswa ekhaya, kuyinto ampere-yehora, kuyilapho endaweni ethile yobuchwepheshe azungeze emibili nengxenye. voltage battery

Ishaja ye-screwdriver has a ebanzi kakhulu voltage range - kusuka volts 2.4 kuya 36. Ethandwa kakhulu ziphoqa kuyizinto amathuluzi e-9, 12 no-14 volts. Okokuqala okubili ongakhetha anemisila elektrootvortki futhi ungenantambo isikudilayiva amathuluzi amandla amandla amaningi, isibonelo, sokuprakthiza - elokugcina.

Nge isitoreji efanele kanye nokusetshenziswa, ishaja oyohlala isikhathi eside.
