Imikhiqizo
I-PDC drill bits nozzles
Isingeniso Sokukhiqiza
I-carbide nozzle enosimende ingenye yezingxenye ezibalulekile ze-diamond drill bit, i-tungsten carbide drill bit nozzle isebenza ekushicileleni, epholile, futhi igcobe amathiphu e-drill bits, ama-carbide nozzles angakwazi ukuhlanza ama-chips amatshe phansi ngokubhoboza. uketshezi ezimeni zokusebenza zengcindezi ephezulu, ukudlidliza, isihlabathi, nodaka oluba nomthelela ngesikhathi sokubheka uwoyela negesi yemvelo.Imibhobho ye-Carbide nayo inomphumela wokuhlukaniswa kwamadwala we-hydraulic.I-nozzle evamile iyisilinda;ingakhiqiza ukusabalalisa kokucindezela okulinganiselayo endaweni yedwala.
Imibhobho ye-tungsten carbide isetshenziselwa ikakhulukazi izingcezu zokusika ezingaguquki kanye nezingcezu ze-cone roller zokupholisa amanzi kanye nodaka lokugeza, ngokuya ngokubhoboza imvelo yendawo, sizokhetha ukugeleza kwamanzi okuhlukile nosayizi bembobo ngokuma kwemibhobho ye-tungsten.
Izinhlobo ze-carbide nozzles
Kunezinhlobo ezimbili eziyinhloko zama-nozzles e-carbide ama-drill bits.Enye inentambo, enye ayinantambo.Imibhobho ye-Carbide ngaphandle kwentambo isetshenziswa kakhulu ku-roller bit, imibhobho ye-carbide enentambo isetshenziswa kakhulu ku-drill bit ye-PDC.Ngokusho kwe-wrench yamathuluzi okuphatha ahlukene, kunezinhlobo ezingu-6 zama-nozzles anentambo yamabhithi e-PDC:
1. Imibhobho yentambo ye-Cross groove
2. Imibhobho yentambo yohlobo lwe-Plum blossom
3. Imibhobho yentambo ene-hexagonal yangaphandle
4. Imibhobho yentambo eyi-hexagonal yangaphakathi
5. Uhlobo luka-Y (3 slot/grooves) imibhobho yochungechunge
6. isondo legiya lokuprakthiza imibhobho encane bese ucindezela imilomo ephukayo.
Ithuluzi le-Kedel lingakhiqiza izinhlobo eziningi zemicu ye-nozzle ye-PDC drill bits ku-metric kanye nentambo yombuso.Intambo kazwelonke eqinile eqinile, intambo ecolekileyo, nemicu ekhethekile efaka ukunemba ibanga lesi-3, ukunemba okuphezulu kakhulu ngokwezinga laseMelika.Ngokwezidingo zakho ze-carbide bit, zingaklanywa ngokushintshana.
Asikwazi nje ukukhiqiza imibhobho ye-tungsten carbide ejwayelekile, kodwa futhi siyakwazi ukukhiqiza imibhobho eyenziwe ngokwezifiso ngokuya ngemidwebo noma amasampula.Imilomo yomlomo iyatholakala ngezitayela ezahlukene kanye nenhlanganisela yosayizi ezinhlelweni zokusebenza eziningi zokumba imigodi ephansi.Amabanga ethu ahlolelwe inkambu adizayinelwe ukuqina okukhulu nokumelana nokugqokwa ezinhlelweni zomthamo wetorque ephezulu.Singakuhlanganisela ibanga elikhethekile lezinto ze-tungsten carbide.Sinolwazi lokukhiqiza ubujamo nosayizi abahlukene bemibhobho ye-tungsten alloy.
