Tungsten carbide Nozzle maka PDC Drill Bit

    PDC drill bits bụ ngwá ọrụ na-akụda okwute nke ọma nke a na-ejikarị eme mmanụ na gas, nchọpụta ala, na mpaghara ndị ọzọ. Ntugharị carbide tungsten bụ otu n'ime ihe mejupụtara ya. A na-etinyekarị ya n'olulu mmiri nke olulu mmiri PDC, ọ na-agbanye mmiri mgbapu mmiri dị elu iji nye ntụ oyi, ihicha,  na nyere aka n'ịkụri nkume. Arụmọrụ ya na-emetụta olulu ahụ ozugbo mana ọ dị

ndụ ọrụ na mkpọpu arụmọrụ.

Ụzọ Njikọ Nozzle:

    Ọ ga-adabarịrị n'oghere mmiri nke PDC drill bit. Njikọ a na-ahụkarị bụ njikọ eriri (mpụga ma ọ bụ nke ime, yana nkenke ọkwa 3A na

    hụ na ọ dịghị ntapu n'okpuru nnukwu nrụgide). Ụfọdụ obere nozzles na-eji nnyonye anya dabara (pịa-fit), nke na-egbochi ịtọpụ mgbe echichi gasịrị.

II. Njirimara ihe eji eme nozzle: Tungsten Carbide (WC)

    1. Elu ike na iyi Nguzogide: Tungsten carbide siri ike bụ nke abụọ naanị diamond, na-eme ka ọ na-eguzogide mbibi site na abrasive irighiri mmiri na-egwupụta mmiri (dị ka nkume ájá na irighiri ígwè), na-agbatị ndụ nozzle.

    2. Nguzogide corrosion: Ọ na-anagide corrosion site na ihe mgbakwunye kemịkalụ na mmiri ngwupu (dị ka nnu na acids).

    3. Mmetụta Nguzogide: Tungsten carbide na-ejikarị cobalt (Co) dị ka a

ihe nkedo, na-enye ụfọdụ ogo siri ike na igbochi mgbaji na-agbaji.

III. Njirimara Nrụpụta Carbide Nozzle

    1. Streamlined Inner Bore: Na-ebelata ọgba aghara ma na-eme ka mmiri dị mma. Ụdị ndị a na-ahụkarị gụnyere:

    2. Oghere kwụ ọtọ: Dị mfe ma na-adịgide adịgide, kwesịrị ekwesị maka ịkụ ala.

    3. Venturi: A converging-diverging Ọdịdị na-abawanye eruba ọnụego na enhances mgbawa mwepụ.

    4. Dị iche iche Sizes: The nozzle n'ime dayameta (nke a 6-16mm) na-ahọrọ dabere na mkpọpu mmiri mmiri ọnụego na chọrọ injection ọsọ.

    Nhazi nke a na-agbanwe agbanwe: Ọ dịghị mkpa iji dochie ihe mkpofu ahụ dum mgbe akwachara, na-ebelata ụgwọ ọrụ.

IV. Isi ọrụ nke tungsten carbide nozzles bụ ndị a:

    1. Ịjụ ndị cutters

Ndị na-egbutu ihe nkedo PDC na-emepụta oke ọkụ ka ha na-atụgharị na nnukwu ọsọ iji bee nkume.  Oke okpomọkụ nwere ike ime ka carbonization na ọdịda nke oyi akwa diamond dara. Mmiri mmiri na-agbapụta nrụgide dị elu nke a na-esi na tungsten carbide nozulu na-ewepụ ọkụ a ozugbo, na-edobe okpomọkụ n'ime ebe nchekwa   (ọ na-adịkarị n'okpuru 700°C)  ma na-egbochi mmebi okpomọkụ.

    2. Nhicha Nkume Ibe

Nkume nkume a na-emepụta n'oge a na-egbutu osisi nwere ike ịgbakọta gburugburu ndị na-egbutu ya, na-eme ka "ịgba bọọlụ apịtị" (ngwakọta nke ịkpụ na mmiri na-agbapụta mmiri na-arapara n'ime ihe ọkụkụ ahụ), na-ebelata nrụpụta nkume. Jet mmiri dị elu nke si na nozulu na-agbasa ngwa ngwa ma na-ewepụ mkpọ ahụ, na-ejigide mmekọrịta dị irè n'etiti onye na-egbu osisi na nkume.

    3. Nkume na-agbaji n'ike n'ike

Jet si nozulu (na ọsọ nke ruru 100-200 m / s) na-emetụta elu nkume, na-emepụta hydraulic cracks. Nke a synergistic mmetụta, jikọtara ya na n'ibu ọnwụ edinam nke cutters, ebelata nkume na-agbaji iguzogide, budata ụba penetration ọsọ, karịsịa na ike formations.

V. Ngwa

A na-ejikarị nozzles carbide mee ihe n'ọnọdụ ndị a:

    1. Nrụpụta dị nro na nke siri ike, dị ka shale na nkume nzu, ebe ha na-akwado ọrụ ịkwa osisi nke ọma nke PDC drill bits.

    2.  Mmiri miri emi / kwụ ọtọ chọrọ nrụgide mgbapụta dị elu na njikwa hydraulic ziri ezi, ebe ntụkwasị obi nke tungsten carbide nozzles dị oke mkpa.

    3.  Nhazi nke ukwuu, dị ka quartz sandstone, na-enye nguzogide iyi ka elu ma e jiri ya tụnyere ọkọlọtọ alloy steel nozzles.
