Itekhnoloji ePhambili: Indlela iiDiamond Bits ezisebenza ngayo ngcono kunezinye izixhobo eziqhelekileyo

1. Ulwakhiwo lokusika kunye neSayensi yezinto ezibonakalayo

• Iibhiti zeDayimani ezifakwe kwi-impregnated: Ezi bhiti zedayimani ezenziweyo zixhonywe ngokulinganayo kwi-matrix yesinyithi eyosiweyo (ngesiqhelo i-tungsten carbide). Njengoko i-matrix iguga kancinci ngexesha lokubhola, iikristale zedayimani ezintsha zihlala zibonakala—zigcina umphezulu wokusika ubukhali rhoqo. Olu yilo oluzihlaziyayo lunika ixesha elide kakhulu kwi-granite erhabaxa, i-quartzite, kunye namatye aqinileyo..
• Iibhiti zePDC ezibekwe phezu komhlaba: Iibhiti zePolycrystalline Diamond Compact (PDC) zisebenzisa iidayimani zemizi-mveliso ezibotshelelwe kwizicuthi ze-tungsten carbide. Zenziwe ngeejiometri zeblade ezilinganisiweyo (iiblade ezi-6–8) kunye nezicuthi ze-premium eziyi-1308mm, zibonelela ngokususwa kwamatye ngendlela eyomeleleyo kwiindlela eziphakathi neziqinileyo ezifana nelitye lekalika okanye udaka. Ukulungiswa kwe-hydraulic kuqinisekisa ukucocwa kakuhle kweenkunkuma, kuthintela ukuqhekeka kweebhiti.
• Izinto Ezintsha Ezixutyiweyo: Iirim ezinee-turbo-segmented zidibanisa iisegments zedayimani ezifakwe i-laser kunye nemiphetho enezikhonkwane, nto leyo ephucula isantya sokusika kwi-concrete kunye ne-ceramic tile. Ubukhulu be-2.4–2.8mm kunye nokuphakama kwe-7–10mm kubonelela ngozinzo lwesakhiwo ngexesha lemisebenzi ye-torque ephezulu.

2. Iindlela zokuvelisa

• Ukuwelda ngeLaser: Kudala unxibelelwano lwesinyithi phakathi kwamacandelo kunye nemizimba yentsimbi, ukumelana namaqondo obushushu afikelela kwi-1,100°C. Oku kuphelisa ukulahleka kwamacandelo kwikhonkrithi eqinisiweyo okanye kwi-deep-hole coring.
• I-Hot-Press Sintering: Isetyenziselwa iibhithi ezifakwe emanzini, le nkqubo idibanisa ii-composites zedayimani-matrix phantsi kobushushu/uxinzelelo olugqithisileyo, iqinisekisa ukusasazwa kwedayimani okufanayo kunye nokumelana nokuguguleka.

3. Iimpawu zoBunjineli obuchanekileyo

• Ukhuseleko lweGauge ye-TSP/PDC: Idayimani eZinzisiweyo ngoThermally (TSP) okanye iziqwenga ezimile okwe-arc zikhusela ububanzi bangaphandle be-bit, zigcina ukuchaneka komngxuma nokuba phantsi koxinzelelo olusecaleni.
• Iiprofayili zeParabolic: Ubuso obungaphantsi, obugobileyo bebhithi bunciphisa indawo yoqhagamshelwano, bunciphisa iimfuno ze-torque ngelixa bunyusa amazinga okungena.

Kutheni Amashishini Ekhetha Iibhiti Zedayimani Eziphambili: Iingenelo Ezingenakuthelekiswa Nanto

• Isantya Nokusebenza Kakuhle: Nciphisa ixesha lokugrumba ukuya kuthi ga kwi-300% xa kuthelekiswa neebhithi zesiqhelo. Iinxalenye ze-turbo ezifakwe nge-laser zisika ikhonkrithi eqinisiweyo ngesantya esiphindwe ka-5–10 kunezinye iindlela ze-carbide.
• Intembeko yeSampuli: Susa ii-cores ezingangcoliswanga nge-close-zero fracturing—ibalulekile kuhlalutyo lwezimbiwa okanye kuvavanyo lwesakhiwo. Ii-PDC bits zibonelela ngama-98% e-core recovery rates kwi-hard rock.
• Ukusebenza kakuhle kweendleko: Nangona iindleko zokuqala ziphezulu, ubomi bezinto ezisetyenzisiweyo (umz., iimitha ezili-150–300+ kwi-granite) bunciphisa iindleko ngemitha nganye ngama-40–60%.
• Ukuguquguquka: Ukusuka kwilitye lesanti elithambileyo ukuya kwikhonkrithi eqinisiweyo ngentsimbi, iimatrices ezikhethekileyo zilungelelanisa ne-UCS (Unconfined Compressive Strength) ukusuka kwi-20–300 MPa.
• Ukuphazamiseka Okuncinci Kwindawo: Ukusebenza ngaphandle kokungcangcazela kugcina ulungelelwaniso lwesakhiwo kwiiprojekthi zokuhlaziya.

Izicelo zeShishini: Apho iDiamond Bits Excel

Ukuhlolwa kweMigodi kunye neJiyoloji

• Isampuli yeMineral Core: Iibhithi ezifakwe ubungakanani be-HQ3/NQ3 (ububanzi obuyi-61.5–75.7mm) zithatha ii-cores ezintle ezivela kwizakhiwo eziqinileyo zamatye aqinileyo. Zidibene neerig ezine-torque ephezulu ezifana neBoart Longyear LM110 (128kN feed force), zifikelela ekungeneni ngokukhawuleza kwe-33% kwi-iron ore okanye kwi-gold deposits.
• IiGeothermal Wells: Iibhithi zePDC zigqobhoza kwi-basalt yentaba-mlilo kunye neengqimba ezirhabaxa, zigcina ukusebenza kumaqondo obushushu angama-300°C+ 1.

Ulwakhiwo kunye nobunjineli bokwakha

• Ukubhola ngolwakhiwo: Iibhithi ze-core ezifakwe nge-laser (68–102mm) zenza imibhobho ye-HVAC okanye iibholiti ze-anchor kwiislabhu zekhonkrithi. Itekhnoloji yokucwangcisa ngaphambi kokusika ivumela imingxunya ecocekileyo, engenamigxobhozo ngaphandle kokuchitha.
• Ukwenziwa kweGranite/Marble: Iibhithi ezimanzi ezifakwe ibrashi (19–65mm) zinqumle imingxunya yeplamba yekhawuntara enemiphetho ekhazimlisiweyo, nto leyo esusa ukuqhekeka. Ukupholisa amanzi kwandisa ubomi beebhithi 3x 510.

Iziseko zophuhliso kunye nezixhobo eziluncedo

• Ukubhoboza iTunnel: Iibhithi zeReamer ezinee-roller cones ezinokuthi zitshintshwe zandise imingxunya yokuqhubela phambili ukuya kwi-1.5m+ diameters zepayipi okanye ii-ventilation shafts.
• Ukuhlolwa kwekhonkrithi: Iisampulu zokukhupha iibhiti ezingenanto ezizi-68mm zokuvavanya amandla okucinezelwa kwiiprojekthi zebhulorho/zendlela.

Itheyibhile: Isikhokelo soKhetho lweeBit ngokwezinto ezisetyenzisiweyo

Iikhrayitheriya zoKhetho oluBalulekileyo:

1. Ukuqina kokwakheka: Sebenzisa iibhithi ezifakwe i-soft-bond kwilitye eline-silicified; khetha i-PDC kwiileya eziqinileyo eziphakathi.
2. Iimfuneko Zokupholisa: Ukubhola ngamanzi (okupholisiweyo ngamanzi) kuthintela ukutshisa kakhulu kwimingxuma enzulu; ukubhola okomileyo kulungele ikhonkrithi enganzulu.
3. Ukuhambelana kweeRig: Tshatisa iintlobo zeeshank (umz., intambo ye-5/8″-11, i-M14) kwiimashini zokubhola. Uyilo lwe-LM110 rig oluyimodyuli luyamkela zonke iibhithi ezisemgangathweni zoshishino.
4. Ububanzi/Ubunzulu: Iibhithi ezingaphezulu kwe-102mm zifuna iibhareli eziqinileyo ukuthintela ukuphambuka.

Izinto ezintsha ezibumba ikamva

• Ukuhlanganiswa kweSmart Drilling: Iisensors ezifakwe kwiibhithi zidlulisela idatha yexesha langempela malunga nokuguguleka, ubushushu, kunye notshintsho lokwakheka kwizixhobo zokulawula izixhobo.
• IiDayimani Ezinesakhiwo Esincinci: Ukumelana nokukrala okuphezulu ngama-40% ngokusebenzisa ii-nano-coatings ukuze ubomi be-bit buhlale ixesha elide.
