Muaj tseeb nyob rau hauv ib lub tsev muaj ntau yam khoom siv tsim nyog los pab kho cov haujlwm thiab tsev neeg cov kev xav tau. Nrog nws, nws yog qhov yooj yim dua thiab sai dua rau ntsia thawv, ntsia hlau ntsia thawv, thiab lwm yam. Thiab txij li thaum lawv muaj ntau qhov loj me me, qhov kev paub ntawm universal devices yog suav tias yog tshuaj pleev. Rau lawv nws yog ib qho ua tau, piv txwv li, kom nqa ib qho cuab yeej drill-screwdriver.
Dab tsi yog qhov siv fais fab?
Roughly speaking, tus laum-tshuab ntsia hlau yog ib lub cuab tam uas nws lub hom phiaj tseem ceeb yog siv qhov ntawm qhov siab yam hauv cov ntaub ntawv sib txawv. Nws tuaj yeem ua ntoo, hlau, yas, tais ( vuas ), cib thiab txawm pob zeb ua ke (qee cov qauv). Txawm li cas los xij, ua kom zoo li qub rau kev xyaum, qhov cuab yeej, muaj qhov tshwj xeeb daim cartridge, qhov twg yuav muab tso rau, tseem siv tau los ntswj thiab ntsaws ntau ntau threaded fasteners (piv txwv, screws, screws). Nrog rau ib lub hnab ntim uas tsim nyog, qhov kev siv lub tshuab no kuj siv tau rau cov hmoov av, sib tsoo thiab ntxuav ntawm ntau qhov chaw.
Yuav ua li cas xaiv ib qho hluav taws xob laum?
Yog tias koj tab tom xav txog qhov xav tau ntawm qhov khoom siv hauv koj lub tsev, ua ntej koj yuav, ua ntej, tag nrho koj tus kheej cov kev xav tau thiab cov kev cai. Qhov tseeb yog tias lub khw niaj hnub muaj ntau yam khoom siv. Piv txwv li, muaj cov cuab yeej siv hauv vaj tse thiab khoom siv. Thawj yog txaus los daws cov teeb meem hauv tsev, kho vaj tse yooj yim thiab kho txhua lub sijhawm. Yog tias koj tos ntau zaus thiab loj thaum kev tsim kho, ces nws tsim nyog yuav yuav ib hom qauv uas muaj lub hwj chim, kev ua kom muaj zog thiab kev muaj zog. Nws yog qhov tseeb hais tias tus nqi ntawm cov kev xyaum ua haujlwm, cov cuab yeej ua luam tshaj li tsev neeg los ntawm ob lossis peb zaug. Tsis tas li ntawd, them nqi rau cov kev tsis txawj, uas feem ntau yuav qhia tau cov hauj lwm thiab kev taw qhia ntawm lub cuab yeej. Qhov tseeb yog hais tias ib co qauv ua tau zoo dua qhov kev ua haujlwm ntawm kev xyaum, thiab qee tus - ib lub cav. Yog li, ua ntej koj yuav nws yog qhov tseem ceeb rau koj los txiav txim seb leej twg - drilling los yog twisting - yog qhov tseem ceeb rau koj. Yog li, piv txwv li, tsis paub yuav ua li cas xaiv ib lub tshuab hluav taws xob, faj seeb rau cov xov tooj ntawm cov lus tshaj tawm ib feeb. Yog hais tias tus ntaus yog tsawg kawg yog 1000 rpm, nws yog zoo li ib tug xyaum. Yog tias koj xav tau ib lub tshuab ntaus ntsaws ntxiv, them nyiaj rau cov khoom siv nrog 500 rpm.
Tseemceeb tseemceeb, peb xav tau li tus yamntxwv uas muaj hwjchim. Rau kev siv hauv tsev, cov qauv pom yuav yog ib qho fais fab-laum ntswj nrog lub zog ntawm 500-800 watts. Lawm, kev pab kiag li muaj zog dua.
Ntau cov laum laum ntswj cov tshuab ua haujlwm tau ua haujlwm los ntawm lub qhov hluav taws xob. Txawm li cas los xij, hauv qee qhov chaw nws tsis txaus lossis tsis ua haujlwm nrog cov khoom siv li ntawd. Yog li ntawd, peb xav kom koj ua tib zoo saib lub roj teeb. Nws tseem ceeb heev uas yuav tau xaiv ib lub tshuab ntaus ntses nrog cov hom roj teeb. Lithium-ion tuaj yeem them tau yog tias tsis tas yuav raug rho tawm. Tab sis cov roj teeb-roj-roj-hydride yog lub teeb thiab ecological. Yog tias ua tau, yuav ib lub taub-ntswj tshuab nrog lub roj teeb uas muaj lub ntim loj rau lub sijhawm ua si.
Ib tug zoo cuab tam muaj peev xwm muaj qee yam ntxiv nta:
- hloov ceev ntawm kev sib hloov;
- rov qab;
- ntau hom cartridge thiab nozzles;
- feem cuam tshuam rau drilling hauv kev ua vaj tse.
Raws li cov lag luam, lub khw muaj ntau yam kev xaiv zoo. Nrov ntawm cov zos thiab cov tub txawg yog cov laum hluavtaws siv fais fab ntawm Bosch (Bosch). Cov txheej txheem txhim khu tsim Makita, AEG, Skil, DeWALT, Metabo. Lub niche tshwj xeeb hauv ntiaj teb kev lag luam ntawm cov cuab yeej siv yog nyob ntawm Japanese Hitachi thiab American Black & Decker. Ntawm cov tuam ntxhab ntawm tsev neeg siv fais fab, Fais tau muaj pov thawj ua zoo heev hauv Interskol.
