I-HMOE/Ulwazi

Amabhithi e-PDC (i-Polycrystalline Diamond Compact bit, okuyi-polycrystalline diamond compact bits) anokusebenza okubanzi uma kuqhathaniswa nemisebenzi yokumba imithombo yamanzi, ebonakala ikakhulukazi kulezi zici ezilandelayo: Okokuqala, ukusebenza kahle kokubhola kwezingcezu ze-PDC kuphezulu uma kuqhathaniswa. Ingakwazi ukuphula ngokushesha amatshe, inciphise isikhathi sokumba, futhi ithuthukise inqubekelaphambili yokwakhiwa kwemithombo yamanzi. Okwesibili, amabhithi e-PDC anokumelana kangcono nokugqoka. Phakathi nenqubo yokumba, ingagcina isimo esihle sokusebenza isikhathi eside, inciphise inani lokushintshwa kwebhithi, futhi inciphise izindleko zokwakha. Ngaphezu kwalokho, izingcezu ze-PDC zinokuvumelana nezimo okuqinile ekwakhekeni. Kungakhathaliseki ukuthi ukwakheka okuthambile noma ukwakheka okuphakathi nendawo, kungaba nomthelela omuhle wokubhoboza. Kodwa-ke, kukhona futhi imikhawulo ethile yamabhithi e-PDC ezinhlelweni zokumba imithombo yamanzi. Isibonelo, kwezinye izimo eziqine kakhulu neziqhumayo, amazinyo okusika amabhithi e-PDC angase aguge kakhulu, athinte impilo yawo yesevisi nokusebenza kahle kokubhola. Ngaphezu kwalokho, intengo yamabhithi e-PDC iphezulu uma kuqhathaniswa, futhi izindleko zokuqala zokutshala izimali zinkulu. Sekukonke, ngesisekelo sokucatshangelwa kabanzi kwezinto ezifana nezimo zokubunjwa, izidingo zokwakha, kanye nezindleko, ukukhethwa okunengqondo nokusetshenziswa kwezingcezu ze-PDC kungaletha izinzuzo eziningi emsebenzini wokumba imithombo yamanzi. Ingabe ucabanga ukusebenzisa izingcezu ze-PDC ukumba imithombo yamanzi? Sicela usithinte.
