PDC drill amasuntswana imilomo
Intshayelelo yeMveliso
Umbhobho we-carbide owenziwe ngesamente lelinye lawona malungu abalulekileyo kwintwana yedayimane yokomba, i-tungsten carbide drill nozzle ifaka umbhobho wokugungxula, ukupholisa, kunye nokuthambisa iingcebiso zamasuntswana okomba, imilomo ye-carbide inokucoca iitshiphusi zamatye kwindawo esezantsi ngokugrumba. ulwelo kwiimeko zokusebenza zoxinzelelo oluphezulu, ukungcangcazela, isanti, kunye nempembelelo eludaka ngexesha lokukhangela i-oyile nerhasi yendalo.Imilomo yeCarbide nayo inefuthe lokuqhekeka kwamatye e-hydraulic.Umbhobho oqhelekileyo u-cylindrical;inokuvelisa i-balanced pressure distribution on rock surface.
Imilomo ye-tungsten ye-carbide isetyenziselwa ikakhulu amasuntswana e-cutter esisigxina kunye ne-cone roller bits yamanzi okupholisa kunye nodaka lokuhlamba, ngokokwembiwa kwendawo, siya kukhetha ukuhamba kwamanzi okwahlukileyo kunye nobukhulu bemingxuma kwimilo ye-tungsten nozzles.
Iintlobo zemibhobho ye-carbide
Kukho iindidi ezimbini eziphambili zemilomo ye-carbide yeebhithi zokubhola.Enye intsonkothile, enye ayinamsonto.Imibhobho yeCarbide ngaphandle kwentambo isetyenziswa kakhulu kwi-roller bit, i-carbide nozzles enentambo isetyenziswa kakhulu kwi-drill bit yePDC.Ngokwesixhobo sokuphatha esahlukileyo, kukho iindidi ezi-6 zemilomo ephothiweyo yeebits zePDC:
1. Imilomo yomsonto we-Cross groove
2. Imilomo yodidi lwentyatyambo yePlum
3. Imilomo yomsonto enehexagonal yangaphandle
4. Imilomo yentambo enehexagonal yangaphakathi
5. Uhlobo lwe-Y (i-3 slot / grooves) imilomo yemisonto
6. imilomo bit drill ivili kwaye cinezela imilomo fracturing.
Isixhobo se-Kedel sinokuvelisa uninzi lweentlobo zemisonto ye-nozzle ye-PDC yokomba amasuntswana kwi-metric kunye nentambo yobukhosi.Umsonto orhabaxa odityanisiweyo wesizwe, intambo ecolekileyo, kunye nemisonto eyodwa ebandakanya ukuchaneka kwebanga lesi-3, ukuchaneka okuphezulu kumgangatho waseMelika.Ngokweemfuno zakho ze-carbide bit, zinokuyilwa ngokutshintshiselana.
Asikwazi nje ukuvelisa i-tungsten carbide nozzles eziqhelekileyo, kodwa siyakwazi ukuvelisa imibhobho elungiselelwe ngokwemizobo okanye iisampuli.Imilomo yomlomo ifumaneka kuluhlu olubanzi lweendlela kunye nendibaniselwano yobungakanani kuninzi lwezicelo zokomba ophantsi.Amabakala ethu avavanywe kwintsimi yenzelwe ukuqina okuphezulu kunye nokumelana nokunxiba kwizicelo zomthamo we-torque ephezulu.Sinokudibanisa ibakala elikhethekileyo le-tungsten carbide kuwe.Sinamava okuvelisa iimilo ezahlukeneyo kunye nobukhulu bemibhobho ye-tungsten alloy.
