Natural Daimondi Pang'ono 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.
Kubowola mawonekedwe ovuta kwambiri Ndi koyenera kuti coring ikhale yovuta kwambiri, monga sandstone.
Mawonekedwe
Korona wokhotakhota
Korona wokhotakhota ali ndi maziko osalala
Design Makina owoneka bwino am'madzi
Chipangizocho chimakhala ndi mapangidwe owoneka bwino am'madzi omwe ali oyenera kuthamanga kwambiri.
Ukadaulo
◆ Chodzikongoletsera chokhazikika
Chodzikongoletsera chokhala ndi pakati chimasunga mdulidwe panthawi yobowola.
◆ Njira yapadera ya masanjidwewo
Njira yapadera ya masanjidwewo imapangitsa kuti masanjidwewo agwirizane ndi mawonekedwe ndi mapangidwe, amakwaniritsa kudula
Kuyamba:
Kubowola pakati mpaka zovuta. Ndioyenera kuperekera mawonekedwe apakatikati mpaka ovuta pamlingo winawake wamapangidwe abrasive.
Mawonekedwe
1. Kubowoleza pakati mpaka mwakhama: Ndioyenera kuperekera mawonekedwe apakatikati mpaka ovuta pamlingo winawake wamapangidwe abrasive.
2.High-kachulukidwe dzino dongosolo: Sing'anga ndi mkulu-kachulukidwe dzino dongosolo kamangidwe ndi apamwamba diamondi zachilengedwe akhoza kusintha kuboola liwiro ndi kutalikitsa moyo wa utumiki wa kubowola pang'ono.
3. Njira yapadera ya masanjidwewo: Njira yapadera ya masanjidwewo imapangitsa kuti masanjidwewo agwirizane ndi mawonekedwe ndi mapangidwe, amakwaniritsa zotsogola ndi kuvala diamondi zomwe zimapangitsa pang'ono kupeza ROP yabwinoko.
4.Radiant waterway kamangidwe: Chipangizocho chimakhala ndi mapangidwe owoneka bwino amtundu wamadzi omwe ali oyenera kuthamanga kwambiri.
