The Ridged Diamond Cutting element

Ndị na-egbutu PDC mebere ngalaba mbelata nke PDC ibe n'ibe, na arụmọrụ ha dị oke mkpa na mmetụta mkpọpu nke PDC ibe n'ibe. Ndị na-emepụta ihe na mba ofesi akwụsịbeghị nyocha na mmepe nke ibe ntụtụ PDC.

Ihe nchacha diamond Ridged nwere geometry pụrụ iche nke na-ejikọta ọrụ ịkwa osisi nke ndị na-egbutu PDC na mkpakọ nke ntinye carbide tungsten (TCI). Enwere ike iji mmewere diamond rijide nwere ike iji matriks na nchara nwere nchara iji na-egwupụta oge dị mma na-adịghị mma na-aga n'ihu site na vetikal, mgbanaka, na akụkụ.

The ngwepịa ọrụ n'ime otu, uru bụ dị ka ndị a:

(1) Mmụba arụmọrụ ịkpụcha mbọ maka nkwalite ROP ozugbo

Omume ngwepịa na ịkpụcha ihe nke Ax element na-enweta opekata mpe 22% ntinye miri emi iji nye ROP ngwa ngwa dị elu site na iji otu ịdị arọ na bit na rpm etinyere na ndị na-egbutu PDC. Isi ihe dị na geometry dị n'ụdị riji, nke na-ewepụta tebụl diamond nke dị 70% toro karịa onye na-egbutu oge ma na-enye nguzogide mmetụta ihu dị elu. Njirimara a na-atụgharị gaa na ịdịte aka ka mma yana ọnọdụ adịghị mma maka idowe ROP kachasị n'oge na-agba ọsọ.

(2) Nwelite njikwa na ngwa ntụziaka

Ike mbelata nke nkuku chọrọ na-atụgharị gaa n'okirikiri n'ozuzu ya, mbelata ngbanwe torque na-emeghachi omume, yana njikwa ihu ka mma na ngwa mgbanaka. Uru a na-eme ka ọnụma wuo ka mma yana ROP dị elu, na-enyere aka ịbawanye mgbasa nke mpaghara mmepụta yana belata oge mkpọpu.

E jiri ya tụnyere ndị na-egbutu PDC a na-ahụkarị, ọkpụrụkpụ nke oyi akwa diamond na-abawanye site na 70%. Ejikọta ya na patented usoro nke polycrystalline diamond urughuru size nkesa na ezigbo ihe, n'ihu mmetụta na-eguzogide na-mma, na anwụ ngwa ngwa nke akuakuzinwo bit na-butere enwekwukwa. Ya mere ịgbatị ndụ ọrụ na ịbawanye ROP (ọnụego ntinye); Ejikọtara ọnụ, njirimara ndị a na-enye olulu ahụ ọbụna ike na iguzogide mmetụta na iyi, yana nkwụsị nke ọma na ikpo ọkụ ọkụ.
