Izinzuzo PDC bits

I-Polycrystalline diamond compact (PDC) kanye ne-PDC drill bits yethulwe emakethe amashumi eminyaka ambalwa. Ngalesi sikhathi eside,i-PDC cutter kanye ne-PDC drill bit bahlangabezane nezihibe eziningi ezigabeni zabo zokuqala, baphinde baba nentuthuko enkulu. Kancane kancane kodwa ekugcineni, amabhithi e-PDC kancane kancane ashintsha ama-cone bits ngokuthuthukiswa okuqhubekayo kusisiki se-PDC, ukuqina kwebhithi, kanye nesakhiwo se-hydraulic bit. Amabhithi e-PDC manje athatha ngaphezu kuka-90% wesamba sevidiyo yokumba emhlabeni.

Ibhilidi yokumba idayimane isetshenziswa cishe kuzo zonke izinhlelo zokusebenza ezihlanganisa ukumba amandla e-geothermal, izimayini, umthombo wamanzi, ukumba igesi yemvelo, kanye nokumbiwa kwemithombo kawoyela.

Nazi ezinye izinzuzo ze-PDC bits.

1. Kuyabiza

Amabhithi e-PDC angabiza kakhulu. Ngokungafaniti-ricone bit, azikho izingxenye ezihambayo ku-PDC bit ezizoguga. Idayimane lokwenziwa elibhekene nalo lingaqhuma, kodwa leso sisiki se-PDC singakhishwa futhi sibekwe esisha endaweni yaso. Ukwakha kabusha ibhithi le-PDC ngokuvamile kuvame ukuzungeze ingxenye eyodwa yentengo yokuthenga ibhithi elisha.

2. Izinga Lokungena

Amabhithi e-PDC, ngendlela efanele, anenani elimangalisayo lokungena. Ukwakheka amabhithi e-PDC enza kahle kukho kufaka phakathi kodwa akukhawulelwe ku-shale, i-limestone, i-sandstone, nobumba. Amabhithi e-PDC angaba noma yikuphi ukuya ngokushesha izikhathi ezi-3-5 kunamabhithi e-tricone.

3. Ukonga Izindleko

Izingcezu ze-PDC zonga imali. Ngoba izingcezu ze-PDC zibhola ngokushesha okukhulu, kunesikhathi esiningi esilondoloziwe. Isikhathi esilondoloziwe sivumela umshini wokumba ukuthi aqedele imisebenzi eminingi ngesikhathi esifushane. Emsebenzini omncane, kugcinwa amahora nezinsuku. Emsebenzini omkhudlwana, kugcinwa amasonto nezinyanga. Izinzuzo zokuqeda umsebenzi ngokushesha zizohlanganisa ukonga ngamahora abantu kanye nakuphethiloli, ukuhlangabezana kanye/noma ukweqa izikhathi ezimisiwe, nokusebenzisa izingcezu ezimbalwa nezinto ezisebenzisekayo.

Sekukonke, kunezinzuzo eziningi zokumba ngezingcezu ze-PDC. Njengakho konke okunye, imboni yokumba ihlale ishintsha. Ukushintsha kwezobuchwepheshe kanye nokubhola kungaba yinto enhle kakhulu. Amabhithi e-PDC angaba yinguquko eyenza umehluko kuwe.
