I-Tungsten Carbide Nozzles ye-PDC Drill Bits

Izingcezu zokubhoboza ze-PDC, ezinesakhiwo esilula, amandla aphezulu, ukumelana nokugqokwa okuphezulu, kanye nokumelana nomthelela omkhulu, yizici ze-PDC bit nozzle zingobunye bobuchwepheshe obusha obuthathu bokubhola emhlabeni ngeminyaka yawo-1980. Ukusetshenziswa kwensimu kubonisa ukuthi ukubhola kwebhithi yedayimane kulungele ukwakheka okuthambile kuya kokuqina okumaphakathi ngenxa yezinzuzo zesevisi ende, isikhathi esincane sokuphumula, kanye nokubhoboza okungaguquki.

I-nozzle ye-carbide enosimende ingenye yezingxenye ezibalulekile ze-diamond drill bit. Umbhobho we-tungsten carbide drill bit nozzle usebenza ekushicileleni, kuphole, futhi kugcobe amathiphu ezinto zokubhoboza. Imibhobho ye-carbide futhi ingahlanza ama-chips amatshe ngaphansi komthombo ngoketshezi lokumba ngaphansi kwezimo zokusebenza zokucindezela okuphezulu, ukudlidliza, isihlabathi, kanye nomthelela we-slurry 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 nokugeza udaka ngokuya ngokubhola kwendawo. Sizokhetha ukugeleza kwamanzi ahlukene kanye nosayizi bembobo ngesimo se-tungsten nozzles.

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. Imibhobho encane yokugaya isondo bese ucindezela ama-nozzles aphukayo.

I-ZZbetter carbide ingakhiqiza izinhlobo eziningi zemicu ye-nozzle ye-PDC drill bits ku-metric kanye nentambo yombuso. Intambo kazwelonke eqinile ehlanganisiwe, 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 aklanyelwe ukuqina okukhulu nokumelana nokugqokwa ezinhlelweni zomthamo wetorque ephezulu. Singakuhlanganisela ibanga elikhethekile lezinto ze-tungsten carbide. Sinolwazi lokukhiqiza ubujamo nosayizi abahlukene bemibhobho ye-tungsten alloy.

Uma uthanda imibhobho ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma ngemeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi kwekhasi.
