Abantu abaninzi badla ngokudideka xa becinga ukuba bathenge i-drill ye-18V okanye ye-20V. Kubantu abaninzi ukhetho luxhomekeke kuleyo ibonakala inamandla ngakumbi. Kakade ke, i-20v Max ivakala ngathi inamandla amaninzi kodwa inyaniso kukuba i-18v inamandla afanayo. Ukujonga ukufana kunye nomahluko phakathi kwezi mveliso kunokuba ngundoqo ekuqondeni into oyifumanayo xa uthenga nayiphi na kuzo.
Inyaniso malunga neebhetri ze-18v vs 20v:
Xa ususa naziphi na kwezi bhetri zimbini uya kuqonda ukuba zenziwe ngendlela efanayo. Zombini zineeseli zebhetri ezahlukeneyo ezicwangciswe kwiqela lee-5 ezifakwe iingcingo kuthotho. Iqela ngalinye leeseli ezi-5 liqhagamshelwe ngentambo ngendlela efanayo. Oku kwenziwa ukuqinisekisa ukuba ibhetri inenani elikhulu lee-amp hours. Kwenziwa nokuqinisekisa ukuba ibhetri inomthamo olungileyo ngokwee-watt hours.
Ukujonga nzulu ezi seli kutyhila ukuba nganye inemilinganiselo emibini eyahlukeneyo ye-voltage, eyokuqala neyokugqibela. Iseli nganye kwibhetri ye-18v okanye ye-20v inomlinganiselo we-voltage oyi-3.6 volts, nto leyo ethetha ukuba yi-18 volts xa idityanisiwe. Iseli nganye kwibhetri ye-18v okanye ye-20v inomlinganiselo ophezulu we-volts ezi-4, nto leyo ethetha ukuba yi-20 volts xa idityanisiwe. Ngokwenyani abavelisi bebhetri ye-18v basebenzisa umlinganiselo ophezulu ngelixa abavelisi bebhetri ye-20v max basebenzisa umlinganiselo ophezulu. Lo ngumahluko omkhulu phakathi kwezi mveliso zimbini.
Emva kokuqaphela oku kungasentla, kuyacaca ukuba zombini ezi bhetri zivelisa amandla alinganayo. Umahluko kuphela kwindlela ezipapashwa ngayo okanye ezibhalwe ngayo malunga nokulinganiswa kweeseli. Omnye umahluko obalulekileyo kukuba iibhetri ezingama-20v max zixhaphakile eMelika ngelixa iibhetri ezingama-18v zithengiswa ngaphandle kweMelika. Nangona kunjalo, umntu osebenzisa iibhetri ezingama-18v ngaphandle kweMelika ufumana iziphumo ezifanayo nezo usebenzisa ibhetri engama-20v max ngaphakathi kwelizwe.
Kubalulekile ukuqaphela ukuba kukho izixhobo ezenzelwe ukusebenza ngeebhetri ze-18v ngelixa kukwakho neqela lezixhobo ezenzelwe ukusebenza ngeebhetri ze-20v max. Oku kungazisa enye ingxoxo kubantu abaninzi abakhetha ukusebenzisa isixhobo se-20v max kuba sivakala sinamandla ngakumbi. Ulwazi olungezantsi lunokukunceda ukhethe isixhobo esifanelekileyo malunga nokubhola.
I-drill ye-18v vs 20v - Yeyiphi ofanele uyikhethe?
Njengoko kukhankanyiwe apha ngasentla akukho mahluko mkhulu phakathi kweentlobo ezimbini zeebhetri. Nangona kunjalo, kunokubakho umahluko omkhulu xa kufikwa kwiidrill ezisebenzisa uhlobo ngalunye lwebhetri. Ukuze wenze ukhetho olufanelekileyo, uyacetyiswa ukuba ujonge ezi nkcukacha zilandelayo.
Ixabiso lokuqhuba i-drill–Isixa semali osihlawuliswayo kwi-drill esebenzisa ibhetri ye-18v sinokwahluka kwixabiso le-drill yebhetri ye-20v max. Musa ukuthenga i-drill kuba nje ibonisa i-20v max endaweni yoko thelekisa amaxabiso ee-drill ezahlukeneyo ezikwimarike kwaye ugqibezele kuleyo ibonakala ngathi inikezelwa ngexabiso elifanelekileyo. I-drill ye-18v engabizi kakhulu inokukunika ukusebenza okugqwesileyo ngelixa i-drill ye-20v max ebiza kakhulu isenokungabi ntle njengoko ucinga.
Cinga nge-torque -Nokuba ukhetha yiphi i-drill, enye yezona zinto zibalulekileyo ekufuneka uziqwalasele kukuba i-torque ephezulu oyifumanayo ingakanani. Ukuba i-drill ye-18v inika i-torque ephezulu, kufuneka uyenze. Kwelinye icala, ukuba i-drill ye-20v inika i-torque engcono, kufuneka uyikhethe ngaphezu kokhuphiswano lwayo. Okukhona i-torque ephezulu ye-drill, kokukhona iziphumo ezingcono ozifumanayo xa ugqobhoza kwiindawo eziqinileyo.
Ubungakanani kunye nobunzima –Ubungakanani kunye nobunzima bombhobho othile yinto enye ekufuneka uyiqwalasele ngaphambi kokuba uthenge. Umbhobho we-20v onzima kakhulu unokubangela ubunzima obukhulu phakathi kweprojekthi. Akupheleli nje ekubeni udinwe kukuyibamba endaweni, kodwa uya kuzidinisa njengoko usuka kwenye indawo uye kwenye. Kuyacetyiswa ukuba ukhethe umbhobho we-18v okhanyayo kuba unokufumana iziphumo ezingcono. Xa kufikwa kubukhulu konke kuxhomekeke kwinto oza kuyisebenzisela umbhobho wakho. Abo basebenzisa umbhobho kwiindawo ezimxinwa banokufuneka bathenge iimveliso ezincinci. Kwelinye icala abantu abasebenza kwiindawo ezinkulu banokuba nenkululeko yokukhetha umbhobho walo naluphi na ubungakanani ukuba nje uhlangabezana nolindelo lwabo.
Ukusebenziseka –Into enye eyenza i-drill ibe yeyodwa kukuba isebenziseka lula. Kule meko i-drill elungileyo yileyo inezibonisi zokukhanya kunye nezaziso zesandi. Ezi zinto zenza kube lula ukuba nabani na ayisebenzise. Izibane ezinemibala eyahlukeneyo zinokunika ulwazi malunga nezicwangciso zangoku kunye namandla akhoyo. Kungcono ukuba ukhethe i-drill ye-18v enezi mpawu kunokuba ukhethe i-drill ye-20v max ngaphandle kwazo.
Ibalulekile uphawu –Ngaphambi kokuba uthenge nantoni na, zinike ixesha lokufunda ngeemveliso ezahlukeneyo kwimarike. Yenza uluhlu lwezona zithembekileyo phezulu. Sebenzisa olu luhlu ukuhluza iimveliso ezahlukeneyo kwimarike. Iimpawu ezifanaIMakitakwayeI-Dewaltziphakathi kwezona zidumileyo nezidumileyo yiyo loo nto kufuneka ukhethe izixhobo zazo nokuba ingakanani na i-voltage efunekayo.
Izixhobo –Ukuze umsebenzi ube lula, kuya kufuneka ukhethe iindlela zokuqeqesha ezingasetyenziswa kunye nezixhobo ezahlukeneyo. Oku kuya kukwenza ugqibe iiprojekthi zakho ngexesha elifutshane nangokuchaneka okugqwesileyo.
Ngamafutshane, iibhetri eziphezulu ze-18v vs 20v
Njengoko sele ufundile akukho mahluko phakathi kwebhetri ye-18v kunye ne-20v max ngaphandle kwemigaqo yokuthengisa kunye nendawo yokusebenzisa. Nokuba uthenga eyokuqala okanye eyesibini, amandla okugqibela owafumanayo ekupheleni kwenkqubo ayafana. Ukujonga ngononophelo izixhobo onomdla wokuzithenga yindlela engcono yokwenza isigqibo esifanelekileyo endaweni yokuxhomekeka kwi-voltage ebonisiweyo.
