Yuav ua li cas tsim PDC cutters

PDC Cutter tau tsim thawj zaug los ntawm General Electric (GE) hauv xyoo 1971. nws tau nthuav tawm kev lag luam hauv xyoo 1976 tom qab nws tau raug pov thawj ntau npaum li qhov ua tau zoo ntawm cov pob zeb carbide. PDC cov khoom tam sim no nyob ntau dua 90% ntawm tag nrho cov duab drilling hauv ntiaj teb. Tab sis koj puas paub tias PDC cutters raug tsim li cas? Kuv xav qhia qee cov lus qhia rau koj ntawm no.

Khoom siv

xaiv cov pob zeb diamond hwm zoo, tsoo thiab ua kom zoo dua, ua rau cov khoom me me zoo ib yam, ua kom huv cov khoom siv pob zeb diamond. Rau tungsten carbide substrate peb siv cov hmoov zoo nkauj zoo nkauj thiab cov qib carbide haum nrog kev cuam tshuam siab.

HTHP sintering

1. cov neeg ua haujlwm tshaj lij thiab cov chaw ua haujlwm siab heev los tsim cov PDC cutters

2. tshawb xyuas qhov kub thiab txias hauv lub sijhawm tiag tiag thiab kho lub sijhawm. Qhov kub yog 1300-1500℃. Lub siab yog 6 - 7 GPA.

3. Kev tsim ib thooj ntawm PDC Cutters yuav tsum tau nyob ib ncig ntawm 30 feeb nyob rau hauv tag nrho.

Thawj daim tshuaj ntsuam xyuas

Ua ntej cov khoom loj, tshuaj xyuas thawj daim kom pom seb nws puas ua tau raws li cov neeg siv khoom xav tau rau qhov loj me thiab kev ua haujlwm.

Sib tsoo

1. Dimension sib tsoo: sib tsoo cov kab sab nraud thiab qhov siab. siv lub cylindrical grinder los ua kev sib tsoo sab nraud rau cov khoom lag luam. Vim tias cov khoom siv tau hloov pauv thaum lub sijhawm super-siab siab thiab kub-kub synthesis, cov khoom tau txais yuav tsis muaj cov duab zoo meej thiab ua tau raws li qhov xav tau ntawm cov khoom muag, thiab lub tog raj kheej zoo meej yuav tsum tau txais los ntawm kev sib tsoo sab nraud.

2. chamfer sib tsoo: lub chamfer yuav tsum yog li 0.1-0.5mm nrog lub kaum sab xis ntawm 45; tuschamfer tuaj yeem ua rau hauv av mus rau qib sib txawv raws li tus neeg siv khoom xav tau.

Kev tshuaj xyuas cov khoom tiav

Txhawm rau kom ntseeg tau tias txhua PDC cutters tsim nyog thiab zoo ib yam, peb yuav tsum tau tshuaj xyuas qhov kawg ntawm PDC cutters. Kev tshuaj xyuas cov khoom xws li qhov pom, qhov ntev, thiab kev ua haujlwm ntawm lub cev yuav tsum tau ua, tom qab ntawd muab faib thiab ntim cov khoom tom qab kuaj xyuas kom tsim nyog. Qhov no yog ib kauj ruam tseem ceeb los lav cov khoom zoo; Kev ntsuas ntawm lub thickness ntawm polycrystalline pob zeb diamond yuav tsum tau hais txog thaum lub sij hawm soj ntsuam cov khoom.

Ntim

Cov tsos thiab qhov ntev ntawm cov khoom tawm yuav tsum ua tau raws li cov qauv kev lag luam, ntxiv rau, cov khoom muag thiab qhov ntev yuav tsum tsis txhob hloov pauv thaum lub sijhawm thauj mus los ntev. Ua ntej rau hauv lub thawv yas, ces mus rau hauv ib lub thawv.50 daim nyob rau hauv txhua lub thawv yas.

Ntawm ZZbetter, peb tuaj yeem muab ntau yam ntawm cov cutters tshwj xeeb.
