Ukuqonda iTekhnoloji emva kweeBits zePDC

1) Iimpawu zesakhiwo sePDC drill bits

PDC drill bits zenziwa ngumzimba bit drill, PDC ukusika amazinyo kunye nemilomo. Ziyahlulahlulwe zibe ziintlobo ezimbini: umzimba wentsimbi kunye nomzimba we-matrix ngokwezakhiwo ezahlukeneyo kunye neenkqubo zokuvelisa. Umzimba wesuntswana eliqinileyo le-PDC drill bit yenziwe ngentsimbi yekhabhoni ephakathi kwaye icutshungulwe kusetyenziswa iinkqubo zokwenziwa ngoomatshini. Gqoka imingxuma kwindawo yokusebenza ye-drill bit kwaye uqinise amazinyo okusika i-PDC kwisithsaba se-drill bit kunye ne-press fit fit. Isithsaba se-drill bit siphathwa ngenkqubo yokuqina komphezulu (ukutshiza i-tungsten carbide wear-resistant layer, carburizing, njl.) ukunyusa ukuxhathisa kwayo. Inzuzo ephambili yale drill bit kukuba inkqubo yokuvelisa ilula; i-disadvantage kukuba i-drill bit body ayixhathisi kukhukuliseko kwaye amazinyo okusika kunzima ukukhusela, ngoko ngoku kunqabile ukusetyenziswa. Inxalenye ephezulu ye-drill bit body ye-matrix PDC drill bit ngumzimba wentsimbi, kwaye inxalenye engezantsi yi-tungsten carbide wear-resistant alloy matrix, eyenziwa kwaye yenziwe kusetyenziswa inkqubo ye-metallurgy sintering engumgubo. Sebenzisa i-solder ephantsi yobushushu ukuze udibanise amazinyo okusika iPDC kwiigrooves ezigciniweyo kwi-carcass. I-tungsten carbide matrix inobunzima obuphezulu kwaye iyamelana nokukhukuliseka. Ke ngoko, i-matrix PDC drill bit inobomi obude kunye nevidiyo ephezulu, kwaye ngoku isetyenziswa ngokubanzi.

2) Umgaqo wokusebenza we-PDC drill bit

I-PDC drill bits iqhekeza amatye ngokusika. Amazinyo okusika anokuzilola angakwazi ukusika ngokulula ekubunjweni phantsi kwesenzo soxinzelelo lokugaya, kwaye aqhubele phambili ukucheba ilitye phantsi kwesenzo se-torque. Amazinyo amaninzi okusika iPDC asebenza ngaxeshanye, kwaye ilitye elisezantsi kwequla lineendawo ezininzi ezikhululekileyo, kwaye iliwa liqhekeka ngokulula phantsi kwe-shear, ngoko ke ukusebenza kakuhle kokuqhekeka kwamatye kuphezulu kwaye isantya sokomba sikhawuleza.

3) Ukusetyenziswa ngokuchanekileyo kwe-PDC bits

I-PDC drill bits isebenza kakuhle kumacandelo amakhulu okwakheka okuthambileyo ukuya kokuqina okuphakathi. Ayifanelekanga ukugrumba iileya zegrabile kunye ne-soft and hard strata. Ukusebenzisa uxinzelelo oluphantsi lokomba, isantya esiphezulu kunye nokugrumba okukhulu, i-drill bit inesiphumo esihle.

Phambi kokuba i-drill bit ingene equleni, umzantsi wequla kufuneka ucoceke ukuqinisekisa ukuba akukho zinto ziwa ngentsimbi.

Xa i-drill bit iqala ukuthotywa emthonjeni, uxinzelelo oluncinci lokugaya kunye nesantya esincinci sokujikeleza kufuneka sisetyenziswe ukuqhuba i-drill bit, kwaye ukugaya okuqhelekileyo kufuneka kuqaliswe emva kokuba umzantsi wequla lenziwe. I-PDC drill bit yintwana yokomba edityanisiweyo engenazo naziphi na iindawo ezihambayo kwaye ifanele ukugrumba i-injini yesantya esiphezulu.

Xa ukhetha iumzimba steel PDC drill amasuntswana, kukho izinto ezininzi ekufuneka ziqwalaselwe ukuqinisekisa ukusebenza kakuhle. Okokuqala, kubalulekile ukuvavanya iimeko ezithile zokomba kunye neempawu zokwakheka ukumisela uyilo olufanelekileyo lwe-drill bit kunye neenkcukacha. Izinto ezifana nohlobo lokubunjwa, ubunzulu bokomba kunye nesantya esifunekayo sokomba siya kuba nefuthe ekukhethweni kwesiseko sentsimbi esifanelekileyo somzimba wePDC wokuqhuba umsebenzi.

Ukongezelela, kubalulekile ukuqwalasela ukucwangciswa kwesixhobo kunye nomgangatho xa ukhetha i-steel-bodiedPDC drill bits. Ukubekwa kunye nobukhulu bezixhobo zokusika zidlala indima ebalulekileyo ekunqumeni ukusebenza kakuhle kunye nokuqina kwe-drill. Izixhobo zokusika ezikumgangatho ophezulu zisebenzisa iteknoloji yePDC ephucukileyo inokuphucula ukusebenza ngokubanzi kunye nobomi benkonzo ye-drill bit, okwenza kube lutyalo-mali olufanelekileyo kwiiprojekthi zokomba zexesha elide.

Ukongeza, uyilo lomsebenzi we-hydraulic we-drill bit ayinakuhoywa. Inkqubo esebenzayo ye-hydraulic ibalulekile ekugcineni izakhiwo zokusika zicocekile kwaye zipholile, ngakumbi kwiimeko ezinzima zokomba. Inkqubo eyenziwe kakuhle ye-hydraulic inceda ukukhusela i-bit pelletizing kwaye iqinisekisa ukususwa okuSebenzayo kokusikwa, kunceda ukuphucula ukusebenza kokugaya kunye nobomi be-bit.

Ngamafutshane, ngokuqwalasela iimfuno ezithile zokomba kunye nokukhetha umgangatho wensimbi-umzimba we-PDC we-drill bits kunye noyilo oluchanekileyo kunye neempawu, iingcali zokomba zinokwandisa ukusebenza ngokufanelekileyo kunye nokufezekisa iziphumo eziphezulu kwiifom ezicela umngeni.
