Gusobanukirwa Ikoranabuhanga Inyuma ya PDC

1) Ibiranga imiterere ya PDC imyitozo

PDC imyitozo bigizwe na drill bit umubiri, PDC ikata amenyo na nozzles. Bagabanijwemo ibice bibiri: umubiri wibyuma numubiri wa matrix ukurikije imiterere itandukanye nuburyo bwo gukora. Umubiri wose wa biti ya PDC ya drill bit ikozwe mubyuma biciriritse kandi bitunganywa hakoreshejwe uburyo bwo gukora imashini. Gucukura umwobo hejuru yumurimo wa biti hanyuma uhambire PDC ikata amenyo kugeza ku kamba rya biti hamwe na kanda. Ikamba rya biti ya drilite ikorwa hamwe nuburyo bukomeye (gutera tungsten karbide yihanganira kwambara, carburizing, nibindi) kugirango irusheho kurwanya isuri. Inyungu nyamukuru yiyi myitozo ni uko inzira yo gukora yoroshye; ibibi ni uko umubiri wa drill bit bitarwanya isuri kandi amenyo yo gutema biragoye kuyirinda, kubwubu ntabwo akoreshwa gake. Igice cyo hejuru cyimyitozo ya bito ya matrix PDC drill bit ni umubiri wicyuma, naho igice cyo hepfo ni tungsten karbide yambara-idashobora kwihanganira matrike, ikorwa kandi ikorwa hifashishijwe ifu ya metallurgie yo gucumura. Koresha kugurisha ubushyuhe buke kugirango usudire PDC ukata amenyo kubigega byabitswe mumirambo. Tungsten carbide matrix ifite ubukana bwinshi kandi irwanya isuri. Kubwibyo, matrix PDC drill bit ifite ubuzima burebure n'amashusho maremare, kandi ubu irakoreshwa cyane.

2) Ihame ryakazi rya PDC imyitozo bito

PDC imyitozo ya bits yamenagura amabuye mugukata. Kwikuramo amenyo yo kwikata birashobora guca muburyo bworoshye mugikorwa cyumuvuduko wogucukura, hanyuma ugatera imbere kugirango wogoshe urutare munsi yumuriro. PDC nyinshi yo guca amenyo ikora icyarimwe, kandi urutare rwo hepfo yiriba rufite ubuso bwinshi bwubuntu, kandi urutare rucika byoroshye munsi yicyogosho, bityo imikorere yo kumena urutare ni ndende kandi umuvuduko wo gucukura urihuta.

3) Gukoresha neza bits ya PDC

PDC imyitozo ikora neza mubice binini bya homogeneous yoroshye kugeza hagati-bigoye. Ntibikwiye gucukura amabuye ya kaburimbo kandi byoroshye kandi bikomeye. Ukoresheje umuvuduko muke wo gucukura, umuvuduko mwinshi hamwe no gucukura ibintu binini, bito bito bigira ingaruka nziza.

Mbere yuko imyitozo ya biti ijya mu iriba, hepfo y iriba igomba kuba ifite isuku kugirango harebwe ko nta byuma bigwa.

Iyo biti ya myitozo ibanje kumanurwa mu iriba, hagomba gukoreshwa igitutu gito cyo gucukura n'umuvuduko muke wo kuzunguruka kugira ngo ukore bito, kandi gucukura bisanzwe bigomba gusubukurwa nyuma yo gushinga iriba. Imyitozo ya PDC ni bito bitagira umwitozo bitagira ibice byimuka kandi birakwiriye gucukura turbine yihuta.

Iyo uhitamo aumubiri wibyuma PDC imyitozo ya bits, hari ibintu byinshi byo gusuzuma kugirango tumenye neza imikorere. Ubwa mbere, ni ngombwa gusuzuma imiterere yihariye yo gucukura nibiranga imiterere kugirango hamenyekane igishushanyo mbonera cya bito n'ibisobanuro. Ibintu nkubwoko bwo gushinga, ubujyakuzimu bwimbitse hamwe nibisabwa byihuta byo gucukura bizagira ingaruka kumahitamo yumubiri wibyuma PDC bitobora akazi.

Byongeye kandi, ni ngombwa gusuzuma ibikoresho nibikoresho bifite ireme mugihe uhitamo ibyuma-byumubiriPDC imyitozo. Gushyira hamwe nubunini bwibikoresho byo gutema bigira uruhare runini muguhitamo gukata neza nigihe kirekire cyimyitozo. Ibikoresho byiza byo guca ibikoresho ukoresheje tekinoroji ya PDC irashobora kunoza imikorere rusange nubuzima bwa serivisi ya biti ya drill, bigatuma ishoramari rikwiye mumishinga yo gucukura igihe kirekire.

Mubyongeyeho, igishushanyo mbonera cya hydraulic imikorere ya drill bit ntishobora kwirengagizwa. Sisitemu nziza ya hydraulic ningirakamaro kugirango ibikoresho byo gutema bisukure neza kandi bikonje, cyane cyane mubihe bigoye byo gucukura. Sisitemu ya hydraulic yateguwe neza ifasha kwirinda gutobora bito no kwemeza gukuraho neza ibiti, bifasha kunoza imikorere yo gucukura nubuzima bwa biti.

Muri make, usuzumye ibisabwa byihariye byo gucukura no guhitamo ibyuma byumubiri-PDC byujuje ubuziranenge hamwe nuburyo bukwiye, abahanga mu gucukura barashobora gukoresha neza gucukura no kugera ku bisubizo byiza muburyo bugoye.
