PDC yodula nkhope yopanda dongosolo

M'mbiri yonse ya kubowola mafuta m'mabowo, ogwira ntchito ayesetsa kukonza makina obowola bwino. Malingaliro osiyanasiyana odula, mapangidwe, ndi zida zakhazikitsidwa kuti awonjezere Rate of Penetration (ROP), kukana kuvala, ndi moyo wonse. Tekinoloje yachikhalidwe ya polycrystalline diamondi cutter (PDC) yapindula kwambiri m'zaka khumi zapitazi ndikusintha kofanana ndi kulowera (ROP) pakubowola. Vuto lomwe latsala ndikuwongolera mapangidwe ovuta okhala ndi zingwe zaluso kwinaku akusunga bwino pobowola komanso kuthekera kwakukulu kwa ROP.

Kutsika kwapang'onopang'ono kwa ma bits wamba a polycrystalline diamond compact (PDC) m'mapangidwe olimba abrasive kumathandizira kupanga zinthu zodulira za PDC kuchokera pa pulani kupita kuzinthu zopanda dongosolo. Posintha mawonekedwe amtundu wa PDC cutter face geometry wokhala ndi mawonekedwe osaya kwambiri, kuwongolera kobowola bwino kunawonedwa pakugwiritsa ntchito izi komanso kuwonjezeka kwazithunzi zomwe zapezeka. Kupyolera mu kusanthula zotsatira za ngodya ya back-rake, kudula kuya, ngodya yozungulira, ndi mawonekedwe a miyala pothyola mwala, timapeza kuti wodula wosakonzekera amathyola thanthwe makamaka ndi kuphwanya ndi kumeta ndipo ali ndi mphamvu zambiri kuposa PDC wodula wamba. Ping'ono ya PDC yokhala ndi ma convex ridge PDC cutters ibowoleredwa pamiyala yosanjikiza, miyalayo simakhudzanso ndege ya diamondi mwachindunji koma imalumikizana ndi mzere wozungulira. Mipiringidzo ya odula a PDC imayamba kukhudzana ndi mapangidwewo ndikufinya miyala, zomwe zimapangitsa kuti pakhale kupsinjika pamiyala, zomwe zimapangitsa kuti zikhale zosavuta kung'amba ndi kuthyoka koyambirira. Ntchito yam'munda ikuwonetsa kuti chodulira chosapanga pulani cha PDC ndichosavuta kulowa mkati mwa mapangidwe kuposa chodulira wamba ndipo chimakhala chokhazikika komanso torque yochepa yofunikira.

Ku ZZBETTER, titha kupereka odula ma planar komanso odula a PDC omwe sali planar, pomwe odulira omwe sali olinganiza amatha kukana bwino, kukana kuvala kwapamwamba komanso kukhazikika. Monga makasitomala athu adanena: odula mapulani a PDC ndi anzeru, osavuta kugwiritsa ntchito.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
