Izinto Ezimbili Ezibalulekile Ezingavuthiwe ze-PDC Cutter

undefined


I-PDC cutter iwuhlobo lwezinto eziqinile kakhulu ezihlanganisa idayimane le-polycrystalline ne-tungsten carbide substrate ekushiseni okuphezulu nokucindezela.


I-PDC Cutter yasungulwa okokuqala nguGeneral Electric (GE) ngo-1971. I-PDC Cutters yokuqala yemboni kawoyela negesi yenziwa ngo-1973 futhi ngemva kweminyaka engu-3 yokuhlolwa nokuhlolwa kwensimu, ifakazelwa ukuthi isebenza kahle kakhulu kunezenzo zokuchoboza i-carbide. ama-button bits ngakho-ke bethulwa ngokwentengiso ngo-1976.


Ama-PDC Cutters enziwe nge-tungsten carbide substrate kanye ne-synthetic diamond grit. I-substrate yedayimane ne-carbide ikhula ndawonye ngamabhondi amakhemikhali ngaphansi kwezimo ezishisa kakhulu nezinomfutho ophezulu.


Izinto ezibaluleke kakhulu zabasiki be-PDC yi-diamond grit ne-carbide substrate.


1. Igridi yedayimane

Igridi yedayimane iyisisetshenziswa esibalulekile sabasiki be-PDC. Ngokwamakhemikhali nezakhiwo, idayimane elenziwe ngabantu lifana nedayimane lemvelo. Ukwenza igridi yedayimane kuhilela inqubo elula ngamakhemikhali: ikhabhoni evamile ifudunyezwa ngaphansi kwengcindezi ephakeme kakhulu kanye nezinga lokushisa. Nokho, ekusebenzeni, ukwenza idayimane akulula neze.


Igridi yedayimane ayizinzile kangako emazingeni okushisa aphezulu kunedayimane lemvelo, nokho. Ngenxa yokuthi i-metallic catalyst evaleleke esakhiweni segrit inenani eliphezulu lokunwetshwa okushisayo kunedayimane, ukunwetshwa okuhlukile kubeka amabhondi edayimane ukuya-kwedayimane ngaphansi kwe-shear futhi, uma imithwalo iphezulu ngokwanele, kubangela ukwehluleka kwamabhondi. Uma amabhondi ehluleka, amadayimane alahleka ngokushesha, ngakho i-PDC ilahlekelwa ubulukhuni nobukhali bayo futhi ingasebenzi. Ukuze uvimbele ukwehluleka okunjalo, abasiki be-PDC kufanele zipholiswe ngokwanele ngesikhathi sokumba.


2. I-Carbide substrate

I-Carbide substrate yenziwe nge-tungsten carbide. I-Tungsten carbide (ifomula yamakhemikhali: WC) iyinhlanganisela yamakhemikhali equkethe i-tungsten nama-athomu ekhabhoni. Indlela eyisisekelo kakhulu ye-tungsten carbide iyimpushana empunga ecolekile, kodwa ingacindezelwa futhi yakheke ibe yizimo ngokucindezela nangokucofa.


I-Tungsten carbide isetshenziswa kakhulu ezimayini kuma-top hammer drill bits, izando ze-downhole, ama-roller-cutters, amashizolo okulima ama-longwall, amapiki ama-longwall shearer, ukuphakamisa izinsimbi eziyisicefe, kanye nemishini eyisicefe yomhubhe.


I-Zzbetter inokulawula okuqinile kwezinto ezingavuthiwe ze-diamond grit ne-carbide substrate. Ukwenza i-PDC cutter oilfield drilling, sisebenzisa idayimane elingenisiwe. Kudingeka futhi siyichoboze futhi siyilolonge futhi, senze usayizi wezinhlayiyana ufane. Kudingeka futhi sihlanze impahla yedayimane. Sisebenzisa i-Laser Particle Size Analyzer ukuze sihlaziye ukusabalalisa usayizi wezinhlayiyana, ubumsulwa, kanye nosayizi weqoqo ngalinye lempushana yedayimane. Sisebenzisa izimpushana ezimsulwa zekhwalithi ephezulu ezinamamaki afanelekile ukuze sikhiqize ama-tungsten carbide substrates.


Kwa-Zzbetter, singanikela ngezinhlobonhlobo zabasiki abathile.
