PDC Cutter rau Pob Zeb Diamond Bearing

Ib qho kev lag luam uas ua haujlwm hauv qee qhov chaw hnyav tshaj plaws hauv ntiaj teb qee zaum xav tau hu rau cov khoom siv tawv tshaj plaws rau cov khoom hnav.

Nkag mus rau lub pob zeb diamond, nrhiav pom hauv xyoo 1950. Synthetic diamonds tuaj yeem tiv taus abrasive, kub-kub, thiab corrosive ib puag ncig thiab sawv ntsug rau siab loads.

Kev lag luam roj thiab roj ntev dhau los tau txais kev lag luam pob zeb diamond rau polycrystalline pob zeb diamond compact (PDC) laum khoom, uas tau qhia hauv xyoo 1970. Tsis yog tag nrho (PDC) pob zeb diamond yog tib yam. Nws yuav zoo tib yam, dub rau saum thiab nyiaj hauv qab, tab sis nws tsis ua txhua yam zoo ib yam. Txhua qhov chaw drilling nthuav qhia nws cov kev sib tw tshwj xeeb. Tias yog vim li cas engineers yuav tsum tau tailor txoj cai pob zeb diamond rau txoj cai drilling tej yam kev mob.

Pob zeb diamond yog siv tsis tau raws li cov khoom siv engineering, thiab tuaj yeem siv rau hauv ntau lwm yam kev siv, xws li hnav cov khoom xws li li qub thiab cov ntsaws ruaj ruaj hauv qhov chaw hnyav.

Rau 20 xyoo dhau los, engineers tau muab lub ntiaj teb cov khoom siv tawv tshaj plaws los ua haujlwm tiv thaiv cov kabmob hauv cov khoom siv xws li av nkos motors, hluav taws xob submersible twj (ESPs), turbines, thiab cov cuab yeej drilling.

Polycrystalline Pob Zeb Diamond radial bearings, tseem hu ua PDC bearings, muaj xws li ib tug series ntawm PDC cutters sib sau ua ke (feem ntau yog brazing) nyob rau hauv cov cab kuj rings. Ib tug raug PDC radial bearing teeb muaj xws li ib tug rotating thiab nyob ruaj ruaj bearing nplhaib. Ob lub nplhaib no tawm tsam ib leeg nrog PDC nto ntawm sab hauv txoj kab uas hla ntawm ib lub nplhaib sib txuas ncaj qha nrog PDC nto ntawm sab nraud ntawm lub nplhaib sib txuas.

Kev siv pob zeb diamond bearings ntawm lub tshuab steerable rotary tuaj yeem ua rau cov cuab yeej siv tau lub neej, txo cov cuab yeej loj thiab txo qhov nyuaj los ntawm kev tshem cov ntsaws ruaj ruaj. Ntawm cov av nkos motors, nws txo cov cuab yeej me ntsis-rau-khoov thiab nce lub peev xwm thauj khoom.

Koj tuaj yeem tswj tsis tau dab tsi hauv dej hiav txwv lossis cov av nkos, txawm tias nws yog xuab zeb, pob zeb, grit, av, lossis grime, nws tag nrho mus los ntawm pob zeb diamond-cov kabmob. Pob zeb diamond bearings tuaj yeem ua "zoo nkauj txhua yam."

Yog hais tias ib txwm bearing lub foob tawg, kua qaub, dej hiav txwv, thiab cov av nkos tuaj yeem nkag mus, thiab cov kabmob yuav ua tsis tiav. Lub pob zeb diamond-cov kabmob flips ib txwm coj tus kabmob tsis muaj zog ntawm nws lub taub hau. Muaj pob zeb diamond bearings siv dej hiav txwv kom lawv txias, tig qhov tsis muaj zog rau hauv kev daws teeb meem.

Yog tias koj txaus siab rau PDC cutters thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL rau hauv qab ntawm nplooj ntawv.
