The Ridged Diamond Cutting Element

Odula a PDC amapanga gawo loyambira la ma PDC bits, ndipo magwiridwe antchito awo ndiofunikira pakubowola kwa ma PDC bits. Opanga pang'ono akunja sanayimitsepo kafukufuku ndi chitukuko cha ma PDC cutter bits.

Chodulira cha diamondi cha Ridged chili ndi geometry yapadera yomwe imaphatikiza kumeta ubweya wa odula wamba a PDC ndi kukakamiza kwa tungsten carbide insert (TCI). Dongosolo la diamondi lopindika litha kugwiritsidwa ntchito ndi matrix ndi zitsulo zokhala ndi chitsulo pobowola mipata yabwino yosasinthika mosalekeza kupyola muimirira, ma curve, ndi ofananira nawo.

Kuphwanya ntchito imodzi, zabwino zake ndi izi:

(1) Kuchulukitsa kwachangu pakuwongolera pompopompo ROP

Kuphwanya ndi kumeta ubweya wa chinthu cha Ax kumakwaniritsa kulowa mkati mozama kwa 22% kuti ipereke ROP yapamwamba nthawi yomweyo pogwiritsa ntchito kulemera komweko pa bit ndi rpm yogwiritsidwa ntchito kwa odula wamba a PDC. Chinsinsi chake chili mu geometry yooneka ngati ridge, yomwe imatulutsa tebulo la diamondi lomwe ndi 70% yokhuthala kuposa chodulira wamba pomwe limapereka kukana kwamphamvu yakutsogolo. Izi zimamasulira kuti zikhale zolimba komanso zosawoneka bwino kuti mukhalebe ndi ROP yayikulu nthawi yonseyi.

(2) Kuwongolera kopitilira muyeso kolowera

Kuchepetsa mphamvu yodulira yomwe imafunikira pobowola kumasulira kukhala torque yocheperako, kusinthasintha kwamphamvu kwa torque, komanso kuwongolera nkhope kwa zida pamapindikira. Ubwinowu umathandizira mitengo yomanga bwino komanso ma ROP apamwamba kwambiri, kuthandiza kukulitsa kuwonekera kwa zone ndikuchepetsa nthawi yoboola.

Poyerekeza ndi odula PDC ochiritsira, makulidwe a diamondi wosanjikiza ukuwonjezeka ndi 70%. Kuphatikizidwa ndi chilinganizo chovomerezeka cha polycrystalline diamondi kukula kwa tinthu tating'onoting'ono ndi zinthu zabwino kwambiri, kukana kwapatsogolo kumakulitsidwa, ndipo kulimba kwa kubowola kumakulitsidwa kwambiri. Potero kutalikitsa moyo wautumiki ndikuwonjezera ROP (mlingo wolowera); Kuphatikizana, zinthuzi zimapereka chitunda mwamphamvu kwambiri komanso kukana kukhudzidwa ndi kuvala, komanso kudula bwino komanso kutulutsa kutentha. Izi zimatanthawuza kukhazikika kokhazikika komanso kusasunthika kuti mukhalebe ndi ROP yayikulu nthawi yonseyi.

Ngati mukufuna zodula za PDC ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRANI MAIL pansi pa tsambali.
