Siyakuhalalisela, uzithele kwelinye lamagugu eDewalt. Lesi sici somthelela sidala i-hype enkulu emhlabeni wokumba nokuklinya namuhla. Le modeli edumile iza ngezinhlobonhlobo ezimbili ezihlukene- enye iwuhlobo lwendandatho yengulube, kanti enye iwuhlobo lwe-anvil evalelwe.
Zisebenza ngendlela ehlukile, ngakho-ke khetha ukuthi yimuphi umsebenzi owuthandayo ngaphambi kokuthenga leli thuluzi. Indandatho yengulube ayidingi ithuluzi lokubamba isokhethi. Isebenzisa iwasha ehlukanisayo ukuze igcine isokhethi liqinile endaweni. Ngakolunye uhlangothi, i-anvil evalelwe isebenzisa ithuluzi ukubamba isokhethi liyiqinise endaweni yalo.
Noma ngabe iyiphi okhetha ukuyisebenzisa, yazi ukuthi zombili zihlonishwe abasebenzisi ngokulinganayo. Ukwakhiwa kanye nekhwalithi yalawa mathuluzi kuyahlaba umxhwele. Ngokuza emandleni etorque, leli thuluzi linetorque engu-700 ezinyaweni ngephawundi ngalinye lesisindo. Futhi i-torque ehlukanayo ingamamitha angu-1200 ngephawundi ngalinye.
Ngokuhambisana nalezi zilungiselelo ze-torque, ngaphandle kwemisebenzi evamile yokuklama, uzokwazi ukusebenzisa leli thuluzi ukushintsha amathayi emoto yakho kalula.

Kuzodingeka uthenge ibhethri neshaja ngokuhlukana.
DEWALT DCF887D2 Brushless Impact Driver Kit
Lona umshini onamandla kakhulu ongasebenza isikhathi eside kunemishini eminingi emakethe kuyilapho uletha inani elingenakuvinjelwa lamandla ngawo wonke umsebenzi. Ilula kakhulu, okwenza ilungele ukusetshenziselwa amaphrojekthi adinga amahora amaningi okusebenza.
Ngeke kudingeke ukuthi uphathe ishaja nxazonke. Uma ishajwe ngokugcwele, leli thuluzi lizosebenza liqonde amahora angu-4 ngaphandle kokulibala. Ukuhluka kwama-3-speed kwaleli thuluzi kuyenza isebenze inhlobonhlobo yemisebenzi.
Isilungiselelo sokuqala sesivinini sisebenzisa idrayivu yokunemba eyakhelwe ngaphakathi enikeza isiqondiso esingenasici emisebenzini edinga ukuthi ugcine izandla zakho ziqinile futhi ungene emininingwaneni emincane. Lapha idizayini engasindi nehlangene iyasiza futhi.
Uzokwazi ukufinyelela kuwo wonke amakhona anzima futhi. Futhi, uzoqaphela ukuthi amabhethri anenkomba yokushaja kuwo. Lokhu kuwusizo ngempela ngoba uzokwazi ukuyikhipha ngaphambi kokuba izinga lokushaja lifinyelele ukushaya okugcwele okungu-100% futhi wonge amabhethri akho ekushajweni ngokweqile. Yandisa impilo yebhethri futhi ibenze bahlale isikhathi eside.
Ngaphezu kwalokho, ukubamba kwakho amathuluzi kuzoba ngcono ngenxa ye-hex chuck emangalisayo. Isekela amathiphu angu-1 intshi. Lokhu kuzokwenza ukuphathwa komsebenzi kube lula futhi kube lula kuwe.

I-Dewalt iwuphawu oluthenjwa kakhulu uma kukhulunywa ngalo amathuluzi okwakha anzima. Sebeneminyaka eminingi besebhizinisini futhi bakhonze amakhasimende ngokwethembeka.
Kodwa-ke, akuyona yonke imishini engenasici, ngakho-ke, esikhundleni sokuthembela komkhiqizo ngokungaboni, kufanele wazi izici eziyisisekelo ngomshini wakho ukuze ukwazi ukuthenga ithuluzi elifanele ekuqaleni nje.
Battery
Kusukela enza kahle umklamo ongenazintambo, u-Dewalt uzilahlile ngokuphelele izintambo.
Ngakho-ke, kufanele wazi ukuthi ungayikhetha kanjani idivayisi esekelwe ebhethri. I-Voltage ichaza ukusebenza. Kukhona amabhethri angu-12, 18- kanye no-20-volt. I-voltage ejwayelekile enikeza ukusebenza kahle kakhulu yi-18V. Ama-voltage aphezulu anika ukuqalisa okusheshayo, kodwa-ke azinza ku-voltage engu-18 kuwo wonke umsebenzi.
Bese kuza ama-Amp-hours (Ah), akutshela ukuthi mangaki amahora idivayisi yakho ezosebenza. Amabhethri angu-12V angu-1.1 Ah, kuyilapho, amabhethri angu-18V kanye ne-20V angu-2 Ah. Uma usebenza amahora amade, khetha amathuluzi anamandla aphezulu we-Ah.
motor
Kunezinhlobo ezimbili ezahlukene - motors brushed kanye brushless.
Amamotho angenawo amabhulashi asebenza kahle kakhulu kunama-brushed motors. Izinhlobo ze-18V zinamamotho ama-brushed, kanti amamodeli angu-20V anama-brushless motors. Uma ufuna ukusebenza kweleveli emaphakathi, ukuhamba ne-18V kulungile.
Kodwa-ke, ukuze uthole ikhwalithi eyengeziwe nokubekezela, khetha ama-20V brushless motors. Abiza kakhulu kunezinhlobo ze-18V, kodwa lowo mehluko unxeshezelwa umehluko ekusebenzeni.
Speed
Le mishini iza ngezilungiselelo ezimbili ezihlukene zesivinini - 1 kanye no-3. Ngokusethwa kwesivinini esingu-1, uzothola isivinini esiguquguqukayo futhi, kodwa lokho kuzoncika kumfutho we-trigger. Ngeke ukwazi ukulawula isivinini ngeseshini ngayinye.
Kodwa-ke, ngamamodeli wokusetha ama-3-speed, i-Dewalt iphinde yafaka idrayivu eyakhelwe ngaphakathi enembile, ezojwayela kunoma yisiphi isivinini okhetha ukusebenza ngaso. Unokulawula okwengeziwe lapha.
Ama-IPM
Ukucacisa, imithelela ngomzuzu. Lesi isilinganiso esingcono sokusebenza kwemoto kunejubane noma itorque. Ngokwabashayeli abathintekayo, yilokhu okukutshela ukuthi injini iphenduka ngokushesha kangakanani.
Ukuze wazi i-IPM, hlukanisa inani elingu-in-lbs (intshi-phawundi) abalisebenzisa ku-torque ngo-12.
I-Milwaukee vs. Dewalt Impact Driver
Bobabili laba bashayeli banama-motor-less-less motor. Abashayeli bethonya baseMilwaukee banamamotho asebenza kahle kakhulu anamandla okuletha amandla etorque afika ku-1800 lb/intshi emithelela engu-3700 ngomzuzu.
Uzokwazi ukushintsha phakathi kwezindlela ezi-4 zokulawula idrayivu. Imodi 3 ijabulisa kakhulu. Hhayi ngoba ikhuphukela ku-0-3000 RPM, kodwa ngoba iyinhlanganisela yazo zonke ezinye izilungiselelo zedrayivu. Futhi umphumela uwukusebenza okubushelelezi njengoba kungalethwa ingekho enye idivayisi emakethe.
Leli thuluzi lingasebenzisa inani elikhulu lamandla ukuze libhekane cishe nazo zonke izinhlobo zemisebenzi, enzima nelula.
Umshayeli womthelela we-Dewalt, ngakolunye uhlangothi, ukhuphukela ku-1825 lb./in. ngokwamandla etorque. Ijubane layo liyaguquguquka lize lifike ku-3250 RPM ngemiphumela engu-3600 ngomzuzu.
Ngenxa yamandla etorque aphezulu, uzokwazi ukuba nezinto eziningi ezisetshenziswayo ngaphandle komshayeli womthelela we-Milwaukee bese uyimpompa ukuze unikeze amandla amakhulu uma kunesidingo.
Ngaphandle komehluko omncane emandleni, lawa angamathuluzi amabili anamandla kakhulu emisebenzi enzima emakethe. I-Dewalt ibiza kakhulu kune-Milwaukee, kodwa lokho kungenxa yokuthi inenzuzo yesisindo nosayizi ngaphezu kwe-Milwaukee. Ngakho, khetha ngokuhlakanipha ngokuvumelana okuthandayo.
Ungayisebenzisa kanjani i-Dewalt Impact Driver
Izishayeli zomthelela we-Dewalt ziphakathi kwamathuluzi asebenza kahle kakhulu emakethe. Zinamandla amakhulu etorque, futhi azibangeli ukungcola komsindo. Ukuzisebenzisa kukhululekile ngempela. Kodwa ungayisebenzisa kanjani, uyabuza? Hhayi-ke, vele ulandele izinyathelo ezingezansi!
Isinyathelo 1: Lungiselela zonke izingcezu ezifanele, uzihlikihle, futhi uzigcine zihlangene.
Isinyathelo 2: Faka ibhethri ethuluzini.
Isinyathelo 3: Namathisela izingcezu ezindaweni ezingakwesokudla ethuluzini.
Isinyathelo 4: Setha okuqondiwe bese uqala umsebenzi.
Isinyathelo 5: Hlukanisa izingxenye ezinamathiselwe.
Isinyathelo 6: Zihlanze ngendwangu ethambile eyomile bese uzigcina zonke endaweni epholile neyomile.
imibuzo ejwayelekile ukubuzwa
Q: Iliphi ibhethri okufanele ngihambe ngalo phakathi kuka-20V no-18V?
I-Ans: Kulaba bashayeli, i-18V iyafana ne-20V. Inkampani iveze ukuthi wonke amabhethri ane-voltage ephezulu uma esemusha. Kodwa ngokuhamba kwesikhathi, ukusebenza kwebhethri ngokwemvelo kuyawohloka futhi ekugcineni kufinyelele phezulu ku-18 volts.
Q: Ngingakwazi ukubhoboza izimbobo ngomshayeli wami womthelela?
I-Ans: Yebo, ngamashanki angu-1/4-inch hex. Izimbobo zizoba zinkulu kakhulu ngosayizi. Lawa mathuluzi awanakho ukunemba okuvamise ukudingekile ukuze ubhoboze izimbobo. Kodwa usengawasebenzisela umsebenzi uma ufuna izimbobo ezinkulu.
Q: Ingabe i- umshayeli onomthelela ofanayo nesikrufu somthelela?
I-Ans: Cha. Ungalinaki igama elithi “umthelela.” Manje cabanga ngakho. Umshayeli nesikrufu baphambene. Umshayeli ushayela izikulufu ezintweni. Kanti, isikrufu sisetshenziselwa ukukhulula amantongomane namabhawodi.
Q: Ngingakwazi ukusebenzisa umshayeli onomthelela kimi Amaphrojekthi we-DIY?
I-Ans: Cha. Izishayeli zomthelela zingamathuluzi wamandla ezimboni asetshenziswa kuphela ukusebenza izikulufu ezinkulu nezinye izinto ezisindayo. Azikwazi ukusetshenziselwa ama-DIY noma enye iphrojekthi encane.
Q: Iyini umehluko phakathi komshayeli we-hammer drill kanye nomshayeli onomthelela?
I-Ans: Abashayeli be-Impact babhoboza izingcezu ezindongeni. Okukhethekile kwabo ukuthi banesando esakhelwe ngaphakathi esidonsa ngokuzenzakalelayo futhi sishaye izinsimbi zokubhoboza lapho zibhajwa emigodini.
Ngakolunye uhlangothi, abashayeli be-drill bane-chuck kuphela yokusebenzisa izinsimbi zokubhoboza ezindongeni. Abanawo umsebenzi wesando. Lapho ama-drill bits ebhajwa, uzodinga ukusebenzisa isando kuwo ngesandla.
