PDC Cutter don PDC Core Bit

PDC core bit an gina shi tare da masu yankan PDC da jikin matrix ko jikin karfe. PDC core bit yana da kyau don aikace-aikace tare da na'urori masu ƙarfi masu ƙarfi waɗanda ke aiki a ƙananan saurin juyawa. Amma rayuwa da shigar ciki na iya zama mafi kyawu idan aka kwatanta da abubuwan da aka saita na saman.

PDC core bit yana da sandunan lu'u-lu'u masu yawa da yawa a jikin matrix. Mai yankan PDC ya ƙunshi barbashi na lu'u-lu'u na lu'u-lu'u masu kyau waɗanda aka haɗa tare da babban matsi da zafin jiki. A kasan wannan lu'u lu'u lu'u-lu'u akwai ingarma ta tungsten carbide wacce aka yi wa bitar jiki kai tsaye. Ana samun manyan nau'ikan masu yankan PDC guda biyu don PDC core bit: ƙirar lebur na al'ada ko dome. An saita masu yankan PDC akan kambi kuma suna iya ɗaukar manyan nauyin matsawa da ƙarfi waɗanda aka haifar yayin hakowa. Akwai kusan masu yankan PDC guda goma akan jikin matrix, dangane da girman babban bit. Mafi girman girman shine, mafi girman adadin masu yankan PDC akansa.

PDC core bit yana da ramukan ruwa ko buɗaɗɗen cibiya da daidaitacce na bututun ƙarfe. Ana buƙatar nozzles saboda suna samar da jigilar jet mai ruɗani ta cikin raƙuman ruwa don kiyaye wuraren yanke tsafta.

Yawancin nau'ikan duwatsu masu kama da juna kamar shale, dolomite, farar ƙasa, da dutsen yashi ana yin aiki cikin sauƙin aiki tare da bit na PDC. Don mafi tsananin ƙyalli irin su dolomite da limestone, matrix jikin PDC core bit ana amfani dashi akai-akai saboda suna ba da kyakkyawan juriya ga lalacewa. Karfe jikin PDC core bit yawanci ana amfani dashi lokacin aiki akan sifofi masu laushi kamar dutsen yashi. Babban bit ɗin yana aiwatar da aikin askewa ko yanke lokacin da aka sami samuwar. Gudun juyawa na ainihin bit yana da girma sosai fiye da sauran nau'ikan juzu'i na yau da kullun. Hydraulics na PDC core bit yana da ƙira don kiyaye rami mai tsafta da ƙwanƙwasa ƙwanƙwasa sanyi, don haka ƙara tsawon rai.

Idan kuna sha'awar masu yankan PDC kuma kuna son ƙarin bayani da cikakkun bayanai, kuna iya tuntuɓar mu ta waya ko wasiku a hagu, ko Aika wasiƙun Amurka a kasan shafin.
