Dab tsi yog rauj laum?

Hais txog hluav taws xob rauj laum cov khoom me, cia peb nkag siab tias yog hluav taws kub rhaub?

Ib lub rauj rauj yog raws li hluav taws xob laum thiab ntxiv piston nrog ib crankshaft txuas cov kav hlau tsav los ntawm hluav taws xob tsav. Nws compresses huab cua rov qab thiab tawm hauv lub tog raj kheej, ua rau muaj kev hloov pauv hauv cov cua hauv lub tog raj kheej. Raws li cov cua siab hloov pauv, lub rauj relocates nyob rau hauv lub tog raj kheej, uas yog sib npaug los siv rab rauj los mus kov txoj kev sib hloov laum me ntsis. Rauj laum cov khoom lag luam tuaj yeem siv rau ntawm qhov chaw nkev vim tias lawv ua rau cov kev hloov pauv sai sai (nquag cuam tshuam) raws cov kev cuam tshuam nquag) raws li cov yeeb nkab khiav raws li lawv tig. Nws tsis tas yuav ntau phau ntawv ua haujlwm, thiab nws tuaj yeem tho qhov hauv Caas pob zeb kub thiab pob zeb, tab sis tsis hlau, ntoo, yas lossis lwm yam ntaub ntawv.

Qhov tsis zoo yog tias qhov kev co yog qhov loj thiab yuav ua rau muaj kev puas tsuaj ntawm kev puas tsuaj rau cov qauv ib puag ncig. Rau cov steel tuav nyob rau hauv cov qauv sib dhos, cov kav dej laum tsis muaj peev xwm kis tau yooj yim, thiab kev co yuav ua tau ntau lub suab nrov. Yog tsis muaj cov cuab yeej pab muaj kev tiv thaiv txaus tuaj yeem muaj kev puas tsuaj rau kev noj qab haus huv.

Dab tsi yog rab rauj laum me ntsis? Lawv tuaj yeem yog cov ntxhib tsis tshua muaj tseeb los ntawm ob hom hom: SDS Plus thiab SDS Max.

SDS-PLUS - OB PITS thiab ob qhov grooves puag ncig

SDS system tsim los ntawm Bosch xyoo 1975 yog lub hauv paus ntawm ntau ntawm niaj hnub no lub tshuab hluav taws xob laum. Nws tsis paub dab tsi ntxiv yog tus thawj SDS Laum ntsis zoo li. Tam sim no zoo-paub sds-ntxiv rau lub zog tau sib koom ua ke los ntawm Bosch thiab Hilti. Feem ntau txhais tias yog "spannen durch system" (hloov chaw kaw lus nrawm), nws lub npe yog los ntawm cov kab lus German "S Tecken - Kev Nyab Xeeb".

Qhov kev zoo nkauj ntawm SDS Ntxiv yog tias koj tsuas yog thawb lub laum rau hauv lub caij nplooj ntoo hlav-ntim tho chuck. Tsis muaj qhov ua kom nruj. Lub laum me me tsis ruaj khov rau chuck, tab sis swb rov qab thiab tawm thiab piston. Thaum tig, lub laum me ntsis yuav tsis plam tawm ntawm lub chuck ua tsaug rau ob qho Dogles ntawm lub cuab yeej hloov pauv. SDS shank drill bits for hammer drills are more efficient than other types of shank drill bits due to their two grooves, allowing for faster high-speed hammering and improved hammering efficiency. Hauv tshwj xeeb, rauj laum cov khoom siv rau rauj drilling hauv pob zeb thiab qhob txuas tau rau ua tiav shank thiab chuck system ua tshwj xeeb rau lub hom phiaj no. SDD Kev Tshaj Tawm Ceev nrawm yog cov txheej txheem txuas rau niaj hnub no Laum. Tsis tsuas yog nws muab txoj hauv kev sai, yooj yim thiab muaj kev nyab xeeb rau clamp lub laum me ntsis, nws kuj ua kom muaj zog hloov mus rau lub laum.

SDDS-Max - Tsib Qhov Hloov Hloov

SDS-PLUS kuj muaj kev txwv. Feem ntau, cov kov txoj hlua ntawm SDS Plus yog 10mm, yog li drilling me me thiab nruab nrab tsis yog teeb meem. Thaum drilling qhov loj lossis tob qhov, tsis muaj zog torque tuaj yeem ua rau lub laum me ntsis kom tau daig thiab kov kom tawg thaum lub sijhawm ua haujlwm. Bosch tsim SDS-Max raws li SDS-ntxiv, uas muaj peb qhov grooves thiab ob lub pits. Tus kov ntawm SDS MAX muaj tsib grooves. Muaj peb qhib slots thiab ob qhov kev kaw (los tiv thaiv cov laum me ntsis los ntawm ya tawm). Feem ntau hu ua peb qhov grooves thiab ob lub pits hloov siv, tseem hu ua tsib lub pits puag ncig. Lub SDS Max kov tau txoj kab uas hla 18 hli thiab zoo dua rau cov haujlwm hnyav tshaj li SDS-PLUS kov. Yog li ntawd, SDS Max Kov tau muaj zog torque tshaj li SDS-ntxiv thiab yog qhov tsim nyog rau kev siv lub cheeb tsam loj dua laum cov khoom loj thiab tob lub qhov kev sib sib zog nqus. Coob leej ntau tus ntseeg hais tias SDS Max System yuav hloov cov qub SDS system. Qhov tseeb, kev txhim kho loj rau lub kaw lus yog lub piston muaj stroke ntev dua, qhov cuam tshuam yog muaj zog thiab laum me ntsis. Txawm tias tau hloov kho dua rau SDS system, SDS-PLUS yuav siv txuas ntxiv. Lub SDDS-Max 18 hli shank shak diam tau nyob rau hauv cov nqi siab dua thaum siv lub tshuab me me uas ntau thiab tsawg. Nws tsis tuaj yeem hais tau tias yog hloov rau SDS-PLUS, tab sis cov kev ua tiav. Siv hluav taws xob rab phom thiab cov hnyiab tau siv sib txawv txawv teb chaws. Muaj ntau hom hom sib txawv thiab cov cuab yeej hluav taws xob rau cov tes taw hnyav sib txawv thiab laum me me.

Nyob ntawm kev ua lag luam, SDS-ntxiv yog qhov feem ntau thiab feem ntau haum cov tub ntawm 4 hli mus rau 30 hli rau 1-1 / 4 hauv.). Tag nrho ntev 110mm, siab tshaj plaws ntev 1500 hli. SDD-Max feem ntau yog siv rau qhov loj thiab xaiv. Kev cuam tshuam laum cov khoom yog feem ntau ntawm 1/2 nti (13 hli) thiab 1-3 / 4 nti (44 hli). Zuag qhia tag nrho ntev yog feem ntau 12 txog 21 ntiv tes (300 txog 530 hli).
