I-Ridged Diamond Cutting Element

Abasiki bePDC benza iyunithi yokusika eyisiseko yeebhithi zePDC, kwaye ukusebenza kwazo kubalulekile kwisiphumo sokugrumba iibits zePDC. Abavelisi besuntswana laphesheya kolwandle abazange baluyeke uphando kunye nophuhliso lwe-PDC cutter bits.

I-Ridged diamond cutting element ine-geometry ekhethekileyo edibanisa isenzo sokucheba sabasiki be-PDC besiqhelo kunye nokunyanzeliswa kwe-tungsten carbide inserts (TCI). Into yedayimani egobileyo ingasetyenziswa kunye ne-matrix kunye neebhithi ezinomzimba wentsimbi ukugrumba izikhewu ezingahambi kakuhle ngokuqhubekayo ngokuthe nkqo, ijika, kunye necala.

Umsebenzi wokutyumza kwenye, iinzuzo zezi zilandelayo:

(1) Ukonyuka kobuchule bokusika ukuphuculwa kweROP kwangoko

Isenzo sokutyunyuzwa kunye nokuchetywa kwe-Ax element ifezekisa ubuncinci be-22% ukungena nzulu ukubonelela nge-ROP ephezulu ngokukhawuleza usebenzisa ubunzima obufanayo kwi-bit kunye ne-rpm esetyenziswe kubasiki besiqhelo bePDC. Isitshixo sikwijiyometri emile okweroji, evelisa itafile yedayimani etyebe ngama-70% kunesisiki esiqhelekileyo ngelixa ibonelela ngokuxhathisa kwempembelelo yangaphambili ephezulu. Olu phawu luguqulela ukuqina okuphuculweyo kunye neemeko ezibuthuntu zokugcina iROP ephezulu kulo lonke ixesha lokubaleka.

(2) Ulawulo oluphuculweyo kwizicelo ezibhekiselele

Amandla okusika ancitshisiweyo afunwa ngamasuntswana e-drill aguqulela kwi-torque engaphantsi yonke, ukunciphisa ukuguquguquka kwetorque esebenzayo, kunye nolawulo olungcono lobuso besixhobo kwizicelo zegophe. Olu ncedo lwenza amaxabiso angcono okwakha kunye ne-ROPs ephezulu, inceda ukwandisa ukuvezwa kwendawo yemveliso kunye nokunciphisa ixesha lokomba.

Xa kuthelekiswa nabasiki besiqhelo bePDC, ubukhulu bomgangatho wedayimane bunyuswe ngama-70%. Idityaniswe nefomyula enelungelo elilodwa lomenzi we-polycrystalline diamond ukusabalalisa ubungakanani besuntswana kunye neyona nto ifanelekileyo, ukuchasana kwempembelelo yangaphambili kuphuculwe, kwaye ukuqina kwe-drill bit kuphuculwe kakhulu. Ngaloo ndlela ukwandisa ubomi benkonzo kunye nokwandisa i-ROP (izinga lokungena); Idityanisiwe, ezi mpawu zinika i-ridge amandla ngakumbi kunye nokuchasana nempembelelo kunye nokunxiba, kunye nokusikwa okusebenzayo kunye nokutshatyalaliswa kobushushu. Oku kuguqulela ukuqina okuphuculweyo kunye neemeko ezibuthuntu zokugcina iROP ephezulu kulo lonke ixesha lokubaleka.

Ukuba unomdla kwi-PDC cutters kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
