Njikwa ogo nke ndị na-egbutu PDC

Ndị na-egbutu PDC nwere oyi akwa Polycrystalline Diamond na mkpụrụ carbide. A na-akpọkwa ndị na-egbutu PDC Polycrystalline Diamond Compact cutters, nke bụ ụdị ihe siri ike. Ojiji nke polycrystalline diamond compact (PDC) na-egbutu na-agbasa ebe niile n'oge a n'ihi nnukwu arụmọrụ ha yana ogologo oge na gburugburu ebe siri ike.

Ihe ndị dị oke mkpa maka ndị na-egbutu PDC na ngwa mkpọpu mmanụ bụ ịdị mma na nkwụsi ike. Ekwenyere m na onye ọ bụla ga-ekwenye. Ma otu esi ejikwa àgwà ahụ?

Iji hụ na mpempe akwụkwọ PDC ọ bụla na-abịa ZZỌkacha mmaaka ndị ahịa nwere oke mma, ZZỌkacha mmaemebela usoro njikwa mma siri ike, gụnyere njikwa akụrụngwa, njikwa usoro mmepụta, yana njikwa ngwaahịa emechara. Onye ọrụ anyị zụrụ azụ nke ukwuu yana ọkachamara na nke raara onwe ya nye. A na-eji ndị na-arụ ọrụ a zụrụ azụ rụọ onye ọ bụla PDC cutter na nrụgide na-achịkwa na ịpị n'oge sintering.

PDC cutter njikwa mma：

1. Akụrụngwa

2. Usoro mmepụta

3. Nyocha nke emechara ngwaahịa

1. Njikwa ihe eji eme ihe

1.1 Maka ịme PDC cutter oilfield ngwa anyị na-eji diamond ebubata. Anyị ga-egwepịa na ịkpụzi ya ọzọ, na-eme ka urughuru size ọzọ edo. Anyị kwesịkwara ime ka ihe diamond dị ọcha.

1.2 Anyị na-eji Laser Particle Size Analyzer iji nyochaa nha nkesa, ịdị ọcha na nha maka ogbe dayamọnd ọ bụla.

1.3 Maka mkpụrụ osisi tungsten carbide anyị na-eji ọkwa ziri ezi nwere mmetụta dị elu.

2. Usoro mmepụta

2.1 Anyị nwere ndị ọrụ ọkachamara na ụlọ ọrụ dị elu iji mepụta ndị na-egbutu PDC

2.2 N'oge mmepụta anyị ga-elele okpomọkụ na nrụgide na ozugbo ma gbanwee n'oge. Ọnọdụ okpomọkụ bụ 1300-1500℃. Nrụgide bụ 6-7 GPA. Ọ bụ ịpị HTHP.

Maka imepụta otu mpempe PDC Cutter ga-achọ ihe dịka nkeji iri atọ na mkpokọta.

Maka ogbe ọ bụla nke ndị na-egbutu PDC, ibe mbụ dị ezigbo mkpa. Tupu mmepụta oke, anyị ga-enyocha mpempe mbụ iji hụ ma ọ na-emezu ihe ndị ahịa chọrọ maka akụkụ na arụmọrụ.

3.Inspection nke okokụre ngwaahịa

Iji hụ na ndị niile na-egbutu PDC ruru eru ma na-agbanwe agbanwe, anyị kwesịrị ọ bụghị naanị ịchịkwa akụrụngwa nyocha na njikwa eruba na teknụzụ, anyị kwesịkwara ịgba mbọ wulite ụlọ nyocha nke nwere akụrụngwa nnwale dị elu iji ṅomie ọnọdụ mkpọpu mmanụ na nwalee ndị na-egbutu PDC na ụlọ ọrụ mmepụta ihe. tupu ebuga ndị ahịa anyị.

Maka njikwa ngwaahịa emechara anyị ga-eme site na akụkụ ndị a:

3.1 Nleba nha na ọdịdị anya:dayameta, elu, diamond ọkpụrụkpụ, chamfer, geometric nha, mgbape, nwa ntụpọ, wdg.

3.2 Njikwa ntụpọ n'ime

Maka njikwa ntụpọ dị n'ime anyị ga-eji ngwa nyocha ultrasonic C-san dị elu ebubata. Maka ndị na-egbutu PDC mmanụ, anyị ga-enyocha iberibe ọ bụla.

Site na sistemụ nyocha C, ultrasonic ife nwere ike banye n'ime oyi akwa PDC wee chọpụta delamination ma ọ bụ ntụpọ oghere ya. Sistemu nyocha C nwere ike ịchọpụta nha na ọnọdụ ntụpọ wee gosi ha na ihuenyo PC. Ọ ga-ewe ihe dị ka nkeji 20 iji mee otu oge nyocha.

3.3 Nnwale nlele arụmọrụ PDC Cutter:

3.3.1 Nnwale Nguzogide eyi:site n'ịtụta ọnụọgụ ole furu efu mgbe ndị PDC gbusịrị granite n'ime oge ụfọdụ, anyị na-enweta oke nkwụsị. Ọ bụ nnukwu mfu n'etiti ndị na-egbutu PDC na granite. N'ịdị elu nke oke ahụ, ka ndị na-eme ihe ike na-eyi ndị PDC Cutters ga-abụ.

3.3.2MmetụtaNnwale nguzogide:Anyị na-akpọkwa ya ule Drop-Weight, na-eji lathe vetikal na ụfọdụ ịdị elu hammering na profaịlụ ịkpụ PDC Cutter, na-enwekarị mmịfe ụfọdụ (ogo 15-25). Arọ nke lathe vetikal a na ịdị elu atọrọ ya ga-egosi ka mmetụta mgbochi PDC a ga-esi bụrụ.

3.3.3 Nnwale nkwụsi ike ọkụ:Ebumnuche ya iji nwalee ma PDC Cutters kwụsiri ike nke ọma n'okpuru ọnọdụ ọrụ okpomọkụ dị elu. Na laabu, anyị na-etinye PDC cutters n'okpuru 700-750℃na 10-15 nkeji na nyochaa diamond oyi akwa ọnọdụ mgbe eke jụrụ na ikuku. Ọtụtụ mgbe, usoro a ga-eso ya na nguzogide iyi ọzọ yana nguzogide mmetụta iji tụnyere ịdịmma PDC cutter tupu ule na mgbe ule gasịrị.
