Ngwa abụọ dị mkpa nke akụrụngwa nke PDC Cutters

PDC cutter bụ ụdị ihe siri ike nke na-ejikọta ola diamond polycrystalline na mkpụrụ osisi tungsten carbide na oke okpomọkụ na nrụgide.

Emepụtara PDC Cutter nke mbụ site na General Electric (GE) na 1971. Emere ndị mbụ PDC Cutters maka ụlọ ọrụ mmanụ na gas na 1973 na mgbe afọ 3 nke nnwale na nnwale ubi, egosipụtara na ha na-arụ ọrụ nke ọma karịa omume ịkụpịa carbide. bọtịnụ bọtịnụ ka ewebata ha na azụmaahịa na 1976.

A na-eme ndị na-egbutu PDC site na mkpụrụ osisi tungsten carbide na grit diamond sịntetị. Mkpụrụ diamond na carbide na-etokọ ọnụ site na njikọ kemịkalụ n'okpuru oke okpomọkụ na ọnọdụ nrụgide dị elu.

Ihe kachasị mkpa nke ndị na-egbutu PDC bụ diamond grit na carbide substrate.

1. diamond grit

Diamond grit bụ isi akụrụngwa maka ndị na-egbutu PDC. N'ihe gbasara kemịkalụ na akụrụngwa, dayamọnd mmadụ mere na dayamọnd eke eke. Ime grit diamond gụnyere usoro dị mfe nke kemịkalụ: carbon nkịtị na-ekpo ọkụ n'okpuru oke nrụgide na okpomọkụ. Otú ọ dị, na omume, ime diamond adịghị mfe.

Nri diamond esighi ike na oke okpomọkụ karịa diamond eke, agbanyeghị. N'ihi na ihe na-eme ka ọ dị mma tọrọ atọ n'ụdị grit nwere ọnụ ọgụgụ dị elu nke mgbasawanye ọkụ karịa diamond, mgbasawanye dị iche iche na-etinye eriri diamond-na-diamond n'okpuru shear na, ọ bụrụ na ibu dị elu, ọ na-ebute ọdịda nkekọ. Ọ bụrụ na nkekọ daa, diamond na-efunahụ ngwa ngwa, ya mere PDC na-efunahụ ike ya na ịdị nkọ ya wee ghọọ adịghị arụ ọrụ. Iji gbochie ọdịda dị otú ahụ, ndị na-egbutu PDC ga-adị mma nke ọma n'oge a na-egwupụta ihe.

2. Carbide mkpụrụ

A na-eme mkpụrụ osisi carbide nke tungsten carbide. Tungsten carbide (usoro kemịkalụ: WC) bụ ngwakọta kemịkalụ nwere tungsten na carbon carbon. Ụdị kachasị nke tungsten carbide bụ ntụ ntụ ntụ dị mma, ma enwere ike ịpị ya ma guzobe ya ka ọ bụrụ ọdịdị site na ịpị na ịpị.

A na-eji Tungsten carbide eme ihe n'ọtụtụ ebe na-egwuputa ihe n'elu hama rock drill bits, hammers downhole, roller-cutters, longwall plow chisels, longwall shearer picks, welie na-agwụ ike reamers, na ọwara na-agwụ ígwè igwe.

Zzbetter nwere njikwa siri ike maka akụrụngwa nke diamond grit na mkpụrụ carbide. Maka ime mkpọpu mmanụ PDC cutter, anyị na-eji diamond ebubata.
