I-PDC OKANYE I-PCD DILL BIT?YINTONI UMAHLUKO?
PDC drill bit kuthetha Polycrystalline Diamond Cutter core bit
Awona maqula amandulo yayingamaqula amanzi, imingxuma engekho nzulu eyembiwa ngesandla kwimimandla apho itafile yamanzi yayisondela kumphezulu, idla ngokwenziwa ngamatye okanye iindonga zamaplanga ezigubungele.
I-PDC yenziwe ngokudibanisa ezinye iileyile zeedayimani ze-polycrystalline (PCD) kunye noluhlu lwe-carbide liner enesamente kwiqondo lokushisa eliphezulu kunye noxinzelelo oluphezulu.
IiPDCs ziphakathi kwezona zinto zingqongqo kuzo zonke izixhobo zedayimani.
I-PCD ithetha ngokulula i-Polycrystalline Diamond: I-PCD iqhele ukwenziwa ngokufaka iikristale ezininzi zedayimani ezinobungakanani obunye kubushushu obuphezulu kunye noxinzelelo oluphezulu.I-PCD inokuqina okuhle kokwaphuka kunye nokuzinza okuhle kwe-thermal, kwaye isetyenziselwa ukwenza amasuntswana okomba wejoloji.
I-PDC ineengenelo zokumelana nokunxiba okuphezulu kwedayimani kunye nokuqina okuhle kwe-carbide.
Sinikezela nge-PDC drill bits ezenziwe ngoluhlu lwabasiki bemilo okanye i-polycrystalline diamond compacts (PDC) eboshwe emzimbeni.
I-PDC Cutters zenziwe kwi-carbide substrate kunye ne-diamond grit.Ubushushu obuphezulu obumalunga nama-2800 degrees kunye noxinzelelo oluphezulu malunga ne-1,000,000 yepsi yenza i-compact.I-cobalt alloy ikhona kwaye isebenza njenge-catalyst kwinkqubo ye-sintering.I-cobalt inceda ukudibanisa i-carbide kunye nedayimane.
Njengomthetho jikelele, abasiki abakhulu (19mm ukuya kwi-25mm) banobudlova kunabasiki abancinci.Nangona kunjalo, banokunyusa ukuguquguquka kwetorque.
Abasiki abancinci (8mm, 10mm, 13mm kunye ne-16mm) babonakaliswe ukugrumba kwi-ROP ephezulu kunabasiki abakhulu kwizicelo ezithile.Esinye isicelo esinjalo yi-limestone ngokomzekelo.
Ukongeza, abasiki abancinci bavelisa iinqumle ezincinci ngelixa abasiki abakhulu bevelisa ukusika okukhulu.Ukusikwa okukhulu kunokubangela iingxaki ngokucoca umngxuma ukuba ulwelo lokomba alukwazi ukuthwala ukusika.
(1) okanye (2) Izinto ezithambileyo nezithambileyo ezincangathi- Izinto ezibunjwa kakhulu ezifana nodongwe, imarl, igumbo kunye nesanti engadityaniswanga.

PDC UKUSEKA ISAKHIWO
Ithambekile kakhulu (1) ukuya phakathi (4) uhlobo lwamasuntswana okwakheka kwepdc anobukhulu obunye obulawulayo besisiki sePDC.Isakhiwo sokusika iPDC sichazwa ngale ndlela ilandelayo:
I-2 - le bit inabasiki abaninzi be-19mm
3 - le bit inama-13 mm abasiki
I-4 – le bit inabasiki be-8 mm ubukhulu becala
Amasuntswana ePDC
