Hoʻokomo ʻo Tungsten Carbide i nā ʻāpana Roller no nā Pōhaku Paʻa ʻo Drilling Core Barrel

ʻO nā mea hoʻokomo tungsten carbide ua kūpono piha ma luna o ka ʻili o nā cones wili, he ʻokoʻa ia mai ka mea kahiko Single cone roller bit i hoʻokomo ʻia he groove-inserts-groove design.The roller bits ua hui pū ʻia me nā ʻāpana ʻelua, ka lima a me ka cone, mai ka nānā ʻana e paʻa ana ka lima. cone ma ka lima.

He mea koʻikoʻi nā mea kila o ka lima a me ka cone no ka maikaʻi, hoʻohana mākou i ke kila 15MnNi4Mo no ka cone, a hoʻohana mākou i ke kila 15CrNiMo no ka lima, ʻo ia ka mea kila maʻamau no ka ʻaila luawai tricone bit.
Ma waena o ka cone-diameter 133mm roller cone bit ma Far Eastern, ua aneane kēia kükohu i ka maikaʻi maikaʻi loa a me ka hana, loaʻa iā mākou nā mea kūʻai maʻamau mai Kina a me South-East Asia, ua noi ʻia nā lua hohonu hohonu i nā papahana kumu no ka hale kiʻekiʻe a me ke kaʻaahi. kūkulu hale.
