Dab tsi yog rab rauj?

Hais txog hluav taws xob rauj laum khoom, cia peb nkag siab ua ntej yog dab tsi yog hluav taws xob rauj?

Ib qho hluav taws xob rauj yog ua raws li kev xyaum hluav taws xob thiab ntxiv lub piston nrog lub crankshaft txuas pas nrig uas tau tsav los ntawm lub tshuab hluav taws xob.Nws compresses cua rov qab thiab tawm hauv lub tog raj kheej, ua rau lub sijhawm hloov pauv huab cua hauv lub tog raj kheej.Raws li cov huab cua hloov pauv, lub rauj reciprocates nyob rau hauv lub tog raj kheej, uas yog sib npaug rau siv ib tug rauj mus tas li kais ib tug rotating laum me ntsis.Rauj laum khoom tuaj yeem siv rau ntawm qhov chaw tawg vim tias lawv tsim cov lus tsa suab nrawm (feem ntau cuam tshuam) raws li cov yeeb nkab laum thaum lawv tig.Nws tsis tas yuav tsum tau ua haujlwm ntau, thiab nws tuaj yeem tho qhov hauv cov cement pob zeb thiab pob zeb, tab sis tsis yog hlau, ntoo, yas lossis lwm yam ntaub ntawv.

Qhov tsis zoo yog qhov kev vibration loj thiab yuav ua rau qee qhov kev puas tsuaj rau cov qauv nyob ib puag ncig.Rau cov hlau tuav hauv cov qauv pob zeb, cov cuab yeej xyaum zoo tib yam tsis tuaj yeem dhau mus zoo, thiab kev co kuj yuav ua rau muaj plua plav ntau, thiab kev co kuj yuav ua suab nrov.Kev tsis nqa cov cuab yeej tiv thaiv zoo tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv.

Dab tsi yog ib qho rauj laum me ntsis?Lawv tuaj yeem paub qhov txawv ntawm ob hom kov: SDS Plus thiab Sds Max.

SDS-Plus - Ob lub qhov thiab ob qhov grooves puag ncig

SDS system tsim los ntawm BOSCH hauv xyoo 1975 yog lub hauv paus ntawm ntau lub tshuab hluav taws xob niaj hnub no.Nws tsis paub tias tus thawj SDS xyaum me ntsis zoo li cas.Tam sim no paub zoo SDS-Plus system tau koom ua ke tsim los ntawm Bosch thiab Hilti.Feem ntau txhais ua "Spannen durch System" (ceev-hloov clamping system), nws lub npe yog muab los ntawm German kab lus "S tecken - D rehen - Safety".

Qhov zoo nkauj ntawm SDS Plus yog tias koj tsuas yog thawb lub laum me ntsis rau hauv lub caij nplooj ntoos hlav-loaded laum chuck.Tsis tas yuav nruj.Lub laum me ntsis tsis ruaj khov rau lub chuck, tab sis swb rov qab los zoo li lub piston.Thaum tig, lub laum me ntsis yuav tsis plam tawm ntawm chuck ua tsaug rau ob lub dimples ntawm lub cuab yeej puag ncig.SDS shank laum khoom rau rauj laum yog qhov ua tau zoo dua li lwm hom shank laum khoom vim lawv ob qhov zawj, tso cai rau kom nrawm nrawm nrawm dua thiab txhim kho hammering efficiency.Tshwj xeeb, rauj laum cov khoom siv rau rauj drilling hauv pob zeb thiab pob zeb tuaj yeem txuas rau lub shank tiav thiab chuck system ua tshwj xeeb rau lub hom phiaj no.SDS ceev tso qhov system yog tus txheej txheem txuas rau niaj hnub no rauj laum khoom.Tsis tsuas yog nws muab txoj hauv kev nrawm, yooj yim thiab nyab xeeb rau clamp lub laum me ntsis, nws tseem ua kom pom lub zog hloov pauv mus rau lub laum me ntsis nws tus kheej.

SDS-Max - Tsib pit round kov

SDS-Plus kuj muaj kev txwv.Feem ntau, txoj kab uas hla ntawm SDS Plus yog 10 hli, yog li drilling qhov me me thiab nruab nrab tsis muaj teeb meem.Thaum drilling qhov loj lossis qhov sib sib zog nqus, qhov tsis txaus torque tuaj yeem ua rau lub laum me ntsis tau daig thiab kov kom tawg thaum lub sijhawm ua haujlwm.BOSCH tsim SDS-MAX raws li SDS-Plus, uas muaj peb grooves thiab ob lub qhov.Tus kov ntawm SDS Max muaj tsib grooves.Muaj peb lub qhov qhib thiab ob lub qhov qhib kaw (kom tiv thaiv lub laum me ntsis los ntawm ya tawm).Feem ntau hu ua peb grooves thiab ob pits round handle, tseem hu ua tsib pits round handle.SDS Max kov muaj txoj kab uas hla ntawm 18 hli thiab zoo dua rau kev ua haujlwm hnyav dua li SDS-Plus kov.Yog li ntawd, SDS Max kov muaj lub zog torque dua li SDS-Plus thiab tsim nyog rau kev siv txoj kab uas hla loj dua qhov cuam tshuam rau kev ua haujlwm loj thiab tob.Ntau tus neeg ib zaug ntseeg tias SDS Max system yuav hloov qhov qub SDS system.Qhov tseeb, qhov kev txhim kho tseem ceeb rau lub cev yog tias lub piston muaj lub zog ntev dua, yog li thaum nws tsoo lub laum me ntsis, qhov cuam tshuam muaj zog dua thiab cov laum me ntsis txiav tau zoo dua.Txawm hais tias kev hloov kho rau SDS system, SDS-Plus system yuav siv txuas ntxiv mus.SDS-MAX's 18mm shank txoj kab uas hla ua rau cov nqi siab dua thaum machining me me xyaum qhov ntau thiab tsawg.Nws tsis tuaj yeem hais tias yog qhov hloov pauv rau SDS-Plus, tab sis yog qhov ntxiv.Hluav taws xob rauj thiab xyaum siv txawv txawv teb chaws.Muaj ntau hom kov thiab cov cuab yeej hluav taws xob sib txawv rau qhov sib txawv rauj qhov hnyav thiab qhov sib txawv me me.

Nyob ntawm kev ua lag luam, SDS-plus yog qhov ntau tshaj plaws thiab feem ntau haum rau cov khoom siv tho los ntawm 4 mm txog 30 mm (5/32 in. to 1-1/4 in.).Tag nrho ntev 110mm, siab tshaj plaws ntev 1500mm.SDS-MAX feem ntau yog siv rau qhov loj dua thiab xaiv.Impact laum khoom feem ntau yog nruab nrab ntawm 1/2 nti (13 mm) thiab 1-3/4 nti (44 mm).Zuag qhia tag nrho ntev yog feem ntau 12 txog 21 ntiv tes (300 txog 530 mm).
