PDC drill amasuntswana imilomo

I-PDC drill bits nozzles, ebonisa isakhiwo esilula, amandla aphezulu, ukuxhathisa ukunxiba okuphezulu, kunye nokumelana nempembelelo ephezulu, ziimpawu ze-PDC bit nozzle yenye yetekhnoloji ezintathu ezintsha zokomba kwihlabathi kwiminyaka yoo-1980. Ukusetyenziswa kwentsimi kubonisa ukuba i-diamond bit drilling ifanelekile kwi-soft to medium-hard formations ngenxa yeenzuzo zobomi obude benkonzo, ixesha eliphantsi lokunciphisa, kunye nokubhoboza okungaguqukiyo.

Intshayelelo yeMveliso

Umbhobho we-carbide owenziwe ngesamente lelinye lawona malungu abalulekileyo kwisuntswana le-diamond drill, i-tungsten carbide drill bit nozzle isebenza ukugungxula, ukupholisa, kunye nokuthambisa iincam zamasuntswana okomba, imilomo ye-carbide inokucoca iitshiphusi zamatye kumzantsi wequla ngolwelo lokomba kwiimeko zokusebenza zoxinzelelo oluphezulu, ukungcangcazela, isanti, kunye nempembelelo yendalo ye-oyile ngexesha lokukhangela i-oyile. 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 yombhobho ye-PDC yokomba amasuntswana kwi-metric kunye nentambo yobukhosi. Umsonto orhabaxa odityanisiweyo, intambo ecolekileyo, kunye neentambo ezikhethekileyo ezibandakanya ibakala lesi-3 lokuchaneka, olona luchanekileyo 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.
