Opatsirana pobowola Pang'ono
Kupanga kwa ROP wapamwamba pobowola mawonekedwe ozama komanso ovuta, kubowoleza PDC nthawi zonse kumaboola kuchokera pansi mpaka pansi mwachindunji kapena kuthamanga kamodzi, kupulumutsa nthawi yayitali ndi mtengo.
Kusiyanitsa ndi tricone bit, PDC kubowola pang'ono kumayenda ndi WOB yotsika koma RPM Yapamwamba, chifukwa chake imagwira ntchito ndi mota yotsikira kuti ikwaniritse liwiro lozungulira.
Magwiridwe a PDC kubowola pang'ono zimadalira kwambiri pa odulira PDC, timapereka yankho lapadera pazofunikira pamitundu yosiyanasiyana.
Kuyamba:
Pachimake Daimondi Pang'ono ali Cylindrical toothed tsamba lomwe lili ndi mitengo malowedwe apamwamba mu zovuta ndi wandiweyani zolimba mapangidwe kulankhulana pulasitiki.
Mawonekedwe
1.Targeted kapangidwe:Ili ndi kapangidwe kake kakuzindikira kwamphamvu komanso kapangidwe kake. Ndioyenera denser shale ndi sandillaceousous sandstone, ndipo miyala ya quartz yokhala ndi abrasiveness yayikulu, miyala yamiyala ndi miyala yamiyala yolumikizidwa ndi mchenga ndiyabwino.
2. Makonda apakati amakona a kondomu: Masamu apadera ndi makonzedwe amkati mwa koboolera amakongoletsa magwiridwe antchito pakatikati pobowola kuti atalikitse moyo wonse wa kubowola.
Ukadaulo
1. Njira yapadera ya masanjidwewo: Kapangidwe ka ufa wa matrix wokhala ndi ufulu wodziyimira payokha waluso komanso ukadaulo wapamwamba wopanga sintering wapangitsa kuti makina a matrix afike pamlingo wapadziko lonse lapansi.
2.Kapangidwe kakang'ono komanso kozama: Njira yozungulira komanso yozama ikuyenda bwino pakutsuka ndi kuyendetsa cuttings ndikupewa kuponyera pang'ono.
