Anthu ambiri amasokonezeka akamaganizira zogula drill ya 18V kapena 20V. Kwa anthu ambiri, chisankho chimadalira chomwe chikuwoneka kuti ndi champhamvu kwambiri. Zachidziwikire kuti 20v Max imamveka ngati ili ndi mphamvu zambiri koma zoona zake n'zakuti 18v ndi yamphamvu mofanana. Kuwona kufanana ndi kusiyana pakati pa zinthuzi kungakhale kofunika kwambiri kuti mumvetsetse zomwe mumapeza mukagula chilichonse mwa izo.
Zoona Zokhudza Mabatire a 18v vs 20v:
Mukachotsa mabatire awiriwa mudzazindikira kuti apangidwa mofanana kwambiri. Onsewa ali ndi ma cell a batire omwe amakonzedwa m'gulu la mawaya asanu motsatizana. Gulu lililonse la ma cell asanu limalumikizidwa kudzera mu waya motsatizana. Izi zimachitika kuti batire ikhale ndi maola ambiri a amp. Izi zimachitikanso kuti batire ikhale ndi mphamvu yabwino malinga ndi maola a watt.
Kuyang'ana mozama maselo awa kukuwonetsa kuti chilichonse chili ndi ma voltage rating awiri osiyana omwe ndi nominal ndi ma maximum. Selo lililonse mu batire ya 18v kapena 20v lili ndi nominal voltage rating ya 3.6 volts zomwe zikutanthauza kuti ma volts 18 ndi nominal akaphatikizidwa. Selo lililonse mu batire ya 18v kapena 20v lili ndi ma maximum rating ya 4 volts zomwe zikutanthauza kuti ma volts 20 ndi ochulukirapo akaphatikizidwa. Mwachidule, opanga batire ya 18v amagwiritsa ntchito nominal rating pomwe opanga batire ya 20v max amagwiritsa ntchito ma maximum rating. Ichi ndiye kusiyana kwakukulu pakati pa zinthu ziwirizi.
Popeza tawona zomwe zili pamwambapa, n'zoonekeratu kuti mabatire onsewa amapanga mphamvu yofanana. Kusiyana kokha kuli mu momwe amalengezedwa kapena kulembedwa malinga ndi kuchuluka kwa maselo. Kusiyana kwina kwakukulu ndikuti mabatire a 20v max ndi ofala ku United States pomwe mabatire a 18v amagulitsidwa kunja kwa United States. Komabe, munthu amene amagwiritsa ntchito mabatire a 18v kunja kwa US akupeza zotsatira zofanana ndi amene akugwiritsa ntchito batire ya 20v max mkati mwa dzikolo.
Ndikofunikanso kudziwa kuti pali zida zomwe zimapangidwira kugwira ntchito ndi mabatire a 18v pomwe palinso gulu la zida zomwe zimapangidwira kugwira ntchito ndi mabatire a 20v max. Izi zitha kupereka chifukwa china kwa anthu ambiri omwe amakonda kugwiritsa ntchito chida cha 20v max chifukwa chimamveka champhamvu kwambiri. Zomwe zili pansipa zikuthandizani kusankha chida choyenera pankhani yobowola.
Chobowola cha 18v vs 20v - Ndi chiyani chomwe muyenera kusankha?
Monga tafotokozera pamwambapa, palibe kusiyana kwenikweni pakati pa mitundu iwiri ya mabatire. Komabe, pakhoza kukhala kusiyana kwakukulu pankhani ya ma drill omwe amagwiritsa ntchito mtundu uliwonse wa batire. Kuti musankhe bwino, mukulangizidwa kuti muyang'ane tsatanetsatane wotsatira.
Mtengo wa chogwirira -Ndalama zomwe mumalipira pa drill yomwe imagwiritsa ntchito batire ya 18v zitha kusiyana ndi mtengo wa drill ya batire ya 20v max. Musagule drill chifukwa chakuti ikusonyeza 20v max m'malo mwake yerekezerani mitengo ya drill zosiyanasiyana zomwe zilipo pamsika ndikugula yomwe ikuwoneka kuti ikuperekedwa pamtengo wabwino. drill yotsika mtengo ya 18v ingakupatseni magwiridwe antchito abwino kwambiri pomwe drill yokwera mtengo ya 20v max singakhale yabwino monga momwe mungaganizire.
Ganizirani za torque -Kaya chobowola chanji chomwe mwasankha chimodzi mwa zinthu zofunika kwambiri zomwe muyenera kuganizira ndi mphamvu yayikulu yomwe mumapeza. Ngati chobowola cha 18v chikupereka mphamvu yayikulu muyenera kuchigwiritsa ntchito. Kumbali inayi ngati chobowola cha 20v chikupereka mphamvu yabwino muyenera kuchigwiritsa ntchito kuposa mpikisano wake. Mphamvu yayikulu ya chobowola ndi zotsatira zabwino zomwe mudzapeza mukabowola pamalo olimba.
Kukula ndi kulemera -Kukula ndi kulemera kwa chobowola china ndi chinthu china chomwe muyenera kuganizira musanagule. Chobowola cha 20v chomwe ndi cholemera kwambiri chingayambitse mavuto ambiri pakati pa polojekiti. Sikuti mumangotopa kuchigwira pamalo pake, komanso mudzatopa mukasuntha kuchokera pamalo ena kupita kwina. Ndikoyenera kuti musankhe chobowola chopepuka cha 18v chifukwa chingapereke zotsatira zabwino. Ponena za kukula, zonse zimadalira zomwe mudzagwiritse ntchito chobowola chanu. Omwe amagwiritsa ntchito zobowola m'malo opapatiza angafunike kugula zinthu zazing'ono. Kumbali inayi, anthu omwe amagwira ntchito m'malo akuluakulu akhoza kukhala ndi ufulu wosankha chobowola cha kukula kulikonse bola ngati chikwaniritsa zomwe akuyembekezera.
Kugwiritsa ntchito bwino –Chinthu chimodzi chomwe chimapangitsa kuti drill ikhale yabwino kwambiri ndi momwe imagwiritsidwira ntchito. Pankhaniyi, drill yabwino ndi yomwe ili ndi zinthu monga zizindikiro za kuwala ndi zidziwitso za mawu. Zinthuzi zimapangitsa kuti aliyense azitha kugwiritsa ntchito. Magetsi amitundu yosiyanasiyana amatha kupereka chidziwitso chokhudza makonda ndi mphamvu zomwe zilipo. Ndibwino kusankha drill ya 18v yokhala ndi zinthuzi m'malo mongogwiritsa ntchito drill ya 20v max popanda izo.
Brand ndi yofunika –Musanagule chilichonse, tengani nthawi yoti mudziwe za mitundu yosiyanasiyana pamsika. Pangani mndandanda wa mitundu yodalirika kwambiri pamwamba. Gwiritsani ntchito mndandandawu kuti mufufuze mitundu yosiyanasiyana pamsika. Mitundu mongaMakitandiDewaltndi ena mwa odziwika bwino komanso odziwika bwino, ndichifukwa chake muyenera kusankha zida zawo mosasamala kanthu za chizindikiro cha magetsi.
Zowonjezera -Kuti ntchito ikhale yosavuta muyenera kusankha zoyeserera zomwe zingagwiritsidwe ntchito pamodzi ndi zowonjezera zosiyanasiyana. Izi zidzakuthandizani kumaliza ntchito zanu mwachangu komanso molondola kwambiri.
Mwachidule, mabatire a 18v vs 20v max
Monga mwaphunzirira, palibe kusiyana kwakukulu pakati pa batire ya 18v ndi 20v max kupatulapo pankhani yotsatsa ndi malo ogwiritsira ntchito. Kaya mugula yoyamba kapena yachiwiri, mphamvu yomaliza yomwe mumapeza kumapeto kwa ndondomekoyi ndi yofanana. Kuyang'ana mosamala zida zomwe mukufuna kugula ndi njira yabwino kwambiri yopangira chisankho choyenera m'malo modalira mphamvu yamagetsi yomwe yasonyezedwa.
