Umgomo Wokusebenza we-Roller Bit Drilling Rig
AI-Tricone drill bitiqukethe amakhanda amathathu okubhoboza amancane, ngalinye linamazinyo amaningi aqinile. Lapho umshini wokumba usebenza, yonke ibhithi yerola izungeza nenduku yokubhola, ebizwa ngokuthi “inguquko.” Ikhanda ngalinye elincane lerola nalo lizungeza ku-eksisi yalo, okusho ukuthi i-roller bit inokubili ukuziphendulela kanye ne-revolution. Ukwengeza, kunendlela yokucindezela phezulu kwenduku yokumba esebenza ngokucindezela okukhulu okuma mpo okuya phansi, ngokuvamile amashumi amaningana amathani.
Ngaphansi kwalokhu kucindezela okuqondile, amazinyo e-alloy aqinile we-roller bit acindezelwa edwaleni, okubangela ukuphuka kwendawo. I-alloy eqinile icindezelwa edwaleni, futhi i-roller bit iyajikeleza futhi ijikeleze, okwenza idwala phakathi kwamazinyo lithole amandla okugunda. Lesi senzo sokugunda siqhubeka sigaya futhi siphuka idwala. Ngakho, iI-Rotary Tricone Drill Bitssebenzisa kokubili ukucindezela kwe-axial kanye nokunyakaza okujikelezayo ukuze uchoboze idwala ngokucindezela, ukugaya, kanye namandla okugunda, okuyinqubo yokuqhekeka kwemishini.
Isithombe esibonisiwe i-roller bit drilling rig yasekhaya, imodeli ye-KY-310. I-"310" ibhekisela kububanzi obuvame kakhulu be-I-Tricone Drill Bitesetshenziswa nale rig, engu-310 mm. Le rig yokubhoboza inezingxenye ezehlukene ezifana nenduku yokubhoboza, uhlaka lwenduku, amasilinda okuphakamisa, ipulatifomu, indlela yokuhamba, izinsimbi zokubhoboza, ojeke, amasistimu okuhlanza uthuli, kanye nemoto enengcindezi ezungezayo. Le rig ibizwa ngokuthi "i-high-rotation" yokumba i-roller bit drilling rig.
Uma kuqhathaniswa nezinsimbi zokubhola ezishaywayo, inzuzo enkulu yama-roller bit drilling rigs yizinduku zokubhola ezinde, ezingadlula amamitha angu-9 lilinye. Ngezinduku ezimbili, ubude obuphelele bufinyelela kumamitha angu-18, okwanele emisebenzini eminingi yezimayini. Ngokuphambene, izinsimbi zokubhoboza ze-percussion rigs ngokuvamile zimfushane, zidinga ukushintshwa kwezinduku ezengeziwe ukuze kubhojwe ekujuleni okufanayo, okunciphisa ukusebenza kahle.
Isithombe lapha sibonisa amathuluzi okubhola we-roller bit rig, okuhlanganisa I-Milled Tooth Tricone Bits. I-torque yakhiwe izingxenye ezine eziyinhloko: induku yokubhoboza, i-rod stabilizer, i-shock absorber, kanye ne-roller bit, njenge.Faka Izingcezu Zokubhoboza Izinyo.
Nakuba i-rig ibonakala iyiyunithi eyodwa, iqukethe izingxenye eziningi ezincane, namazinyo aqinile e-alloy abaluleke kakhulu. Ingemuva le-roller bit libuye libe nama-alloys aqinile, njengalawo atholakala kuwo I-Tungsten Carbide Tricone Bits, ukuthuthukisa ukumelana nokugqoka. II-TCI Tricone Drill Bitsokuboniswe esithombeni sekusetshenziswe izimayini isikhathi esithile, futhi amazinyo e-alloy aqinile asegugile kakhulu. Uma lezi zingcezu zisetshenziswa isikhathi eside kulesi simo, ukusebenza kahle kokumba kuncipha kakhulu. Ezimweni ezinjalo, ama-bits kufanele ashintshwe, noma ama-alloys aqinile angashintshwa ukuze kubuyiselwe ukusebenza.
Ukwengeza, izimbobo ezincane ku-drill bit zixhuma endaweni engenalutho yenduku yokubhoboza, ehlinzeka ngephaseji lomoya. Lapho kubhobozwa, kukhiqizwa imfucumfucu yamatshe, futhi uma ingasuswa ngesikhathi, i-bit izogaya ngokuphindaphindiwe ngokumelene nedwala, kunciphisa kakhulu ukusebenza kahle kokubhola. Lokhu futhi kwandisa ukuguga kwebhithi futhi kufinyeze ubude bayo bempilo. Ngakho-ke, umoya onomfutho ophezulu kufanele usetshenziselwe ukukhipha udoti emgodini. Induku yokubhoboza incane ngobubanzi kunomgodi, idala igebe lokuxosha udoti.
Ngokuthuthuka okuqhubekayo kwezobuchwepheshe kanye nentuthuko kumasu okumba izimayini, ama-roller bit drilling rigs, ikakhulukazi lawo asebenzisaI-Hard Rock Tricone BitsfuthiI-Water Well Tricone Bits, nakanjani zizoshintsha zibe yimishini esebenza kahle kakhulu, ekhaliphile futhi engayingeni imvelo. Siyakukholwa lokhoI-Soft Rock Tricone Bitskanye nokunye okuqanjwe kabusha kuzodlala indima ebaluleke kakhulu ekusebenzeni kwezimayini esikhathini esizayo, okuholela ezimpumelelweni eziphawuleka nakakhulu.
