Tri-Cone Drill Bit: Maikutlo a Kopo

1) Sebopeho sa motheo sa alikotoana tsa li-tricone. 'Mele oa boro: Ho na le likotoana tse tharo tsa meno tse kopantsoeng le ho hokahana hammoho, 'me ho na le likhoele tse hokelang karolong e ka holimo. Gear: 'mele oa tšepe o bōpehileng joaloka khoune o entsoeng ka 'mele oa gear le meno. Meno a arotsoe ka mefuta e 'meli: meno a silafetseng le meno a kenyang, li-bearings le li-nozzles tsa lisebelisoa tsa polokelo ea oli.

2) Ho sebetsa molao-motheo oa bita rolara khoune Harolara khoune hanyanee sebetsa botlaaseng ba seliba, karolo eohle ea ho phunya e potoloha ho pota-potile sebaka sa ho phunya, se bitsoang revolution, 'me li-cones tse tharo li phutholoha ka tlaase ho seliba ho ea ka lilepe tsa tsona, tse bitsoang ho potoloha. Khatello ea ho cheka e mamelletsoeng ke karolo ea ho phunya e sebetsa holim'a lejoe ka meno, e leng se etsang hore lefika le robehe (phello e pshatlehang). Nakong ea ts'ebetso, khoune e kopana ka tlas'a seliba ka meno a le mong le meno a mabeli, 'me boemo ba bohareng ba khoune bo fetoha, e leng se etsang hore sekhahla sa ho phunya se sisinyehe ka nako e telele. Ho thothomela hona ha longitudinal ho etsa hore khoele ea boro e lule e hatella le ho otlolla. Mohala o ka tlase oa ho phunya o fetola matla ana a fetohang nako le nako hore e be matla a amang sebopeho ka meno ho pshatla lefika. Tšusumetso ena le phello ea ho pshatla ke mokhoa o ka sehloohong oa ho phunya li-roller cone ho pshatla majoe.

Ho phaella tabeng ea ho ama le ho pshatla lefika ka tlaase ho seliba, sekoti sa cone sa roller se boetse se hlahisa liphello tsa ho kuta holim'a lejoe le ka tlaase ho seliba. Le hoja khoune e bilika ka tlaase ho seliba, e boetse e etsa hore meno a thellele ka tlas'a seliba. Ho thella ha meno ho baka phello ea ho kuta holim'a lejoe le ka tlaase ho seliba, ho hohola bokatlase ba seliba joalo ka sekotoana sa scraper. Ho thella ha meno ho bakoa haholo-holo ke ho feta-holimo, khoune e thusang le tlhophiso e sisinyehang ea lebili la gear. Tlhophiso e holimo-holimo ea khoune e etsa hore ho thellehe ka lehlakoreng la tangential, 'me tlhophiso ea phetoho ea khoune e etsa hore e thellehe ka lehlakoreng la axial. Ka kakaretso,likotoana tsa ho phunyabakeng sa ho cheka libopeho tse bonolo ho isa ho tse thata-thata li etselitsoe ka holimo-holimo, li-cone tse kopantsoeng le li-shafts tse fetohang; likotoana tsa ho cheka bakeng sa ho cheka libopeho tse mahareng tse thata ho isa ho tse thata li entsoe ka li-cones tse holimo-holimo le tse kopaneng; likotoana tsa ho cheka bakeng sa ho cheka libopeho tse thata haholo le tse khopameng li entsoe ka likhoune tse holimo holimo le tse kopaneng. Li-drill bits hangata li sebelisa likhoune tse le 'ngoe, tse sa thunyeng kapa ho sisinya axis.

3) Tlhophiso le Khetho ea Li-roller Bits Ho na le bahlahisi ba bangata ba li-roller bits, 'me baetsi bana ba li-drill ba fana ka lisebelisoa tsa ho cheka tsa mefuta e sa tšoaneng le mehaho. E le ho nolofatsa khetho le ts'ebeliso ea li-roller cone bits, Mokhatlo oa Machaba oa Likonteraka tsa ho Drilling (IADC) o thehile mokhoa o kopaneng oa maemo le mokhoa oa ho etsa linomoro bakeng sa likotoana tsa li-roller cone lefatšeng ka bophara. IADC e bolela hore mofuta o mong le o mong oa ho phunya o emetsoe ke nomoro ea linomoro tse tharo, 'me moelelo oa nomoro ka' ngoe o tjena:

• Nomoro ea pele e bonts'a mofuta oa leino le sebopeho se loketseng ho cheka: 1- leino la ho sila, sebopeho se bonolo; 2- leino la ho sila, sebopeho se mahareng ho isa bohareng; 3- leino la ho sila, sebopeho se thata, sa abrasive kapa se-abrasive; 4 - e setseng; 5-Leino, sebopeho se bonolo ho isa bohareng; 6-Leino, sebopeho se thata se mahareng; 7-Bopehi ba leino, bo thata, bo hlabang kapa bo hlabang; 8-Leino, sebopeho se thata haholo, se hlabang haholo.
