UmGaqo wokuSebenza we-Roller Bit Drilling Rig
ATricone drill bitineentloko ezintathu zokomba ezincinci, nganye kuzo inamazinyo amaninzi aqinileyo. Xa isixhobo sokugrumba sisebenza, i-roller bit yonke ijikeleza kunye nentonga yokomba, ebizwa ngokuba "yi-revolution." Intloko nganye yerola encinci iphinda ijikeleze kwi-axis yayo, okuthetha ukuba i-roller bit inokuzijikeleza ngokwayo kunye ne-revolution. Ukongeza, kukho umatshini woxinzelelo phezulu kwintonga yokomba esebenza ngoxinzelelo olukhulu oluthe nkqo ukuya ezantsi, amaxesha amaninzi amashumi aliqela eitoni.
Phantsi kolu xinzelelo oluthe nkqo, amazinyo e-alloy aqinileyo e-roller bit acinezelwe elityeni, nto leyo ebangela ukwaphuka kwendawo. I-alloy eqinile icinezelwa elityeni, kwaye i-roller bit iyajikeleza kwaye ijikeleze, ibangele ilitye phakathi kwamazinyo ukuba libe nempembelelo yokucheba. Esi senzo sokucheba ngakumbi sicola kwaye siqhekeza ilitye. Ngoko ke, iI-Rotary Tricone Drill Bitssebenzisa zombini uxinzelelo lwe-axial kunye nokunyakaza okujikelezayo ukutyumza ilitye ngokucinezela, ukucola, kunye nemikhosi yokucheba, okuyinkqubo yokuqhekeka komatshini.
Umfanekiso obonisiweyo yi-roller bit drilling rig yasekhaya, imodeli ye-KY-310. I "310" ibhekisela kwidayamitha eqhelekileyo yeTricone Drill Bitisetyenziswe nale rig, eyi-310 mm. Le rig yokomba inamacandelo ahlukeneyo afana nentonga yokomba, ifreyim yentonga, iisilinda zokuphakamisa, iqonga, indlela yokuhamba, i-drill bits, iijekhi, iinkqubo zokucoca uthuli, kunye nemoto yoxinzelelo olujikelezayo. Le rig ibizwa ngokuba yi "high-rotation" roller bit rig rig.
Xa kuthelekiswa ne-percussion drilling rigs, eyona nzuzo inkulu ye-roller bit drilling rigs ziintonga zokomba ezinde, ezinokudlula iimitha ezili-9 inye. Ngeentonga ezimbini, ubude obupheleleyo bufikelela kwiimitha ezili-18, ezaneleyo kwimisebenzi emininzi yezimayini. Ngokuchaseneyo, ii-rods zokomba ze-percussion rigs zimfutshane ngokubanzi, zifuna ukutshintshwa kweentonga ezininzi ukugrumba kubunzulu obufanayo, okunciphisa ukusebenza kakuhle.
Umfanekiso apha ubonisa izixhobo zokomba kwi-roller bit rig, kuquka Amasuntswana eTricone yezinyo eMilled. I-torque yenziwe ngamacandelo amane aphambili: intonga yokomba, intonga yokuzinzisa, i-absorber, kunye ne-roller bit, njenge.Faka Amasuntswana oQobo lwezinyo.
Nangona i-rig ibonakala iyiyunithi enye, iqulethe iindawo ezininzi ezincinci, kunye namazinyo e-alloy anzima kakhulu. Ngasemva kwe-roller bit ikwabonisa ii-alloys ezinzima, ezifana nezo zifunyenwe kuyo Amasuntswana eTungsten Carbide Tricone, ukuphucula ukumelana nokunxiba. II-TCI Tricone Drill Bitseboniswe emfanekisweni sele isetyenziswe emigodini ixesha elithile, kwaye amazinyo aqina ingxubevange aguge kakhulu phantsi. Ukuba ezi bits zisetyenziswa ixesha elide kule meko, ukusebenza kakuhle kokomba kuyancipha kakhulu. Kwiimeko ezinjalo, ii-bits kufuneka zitshintshwe, okanye ii-alloys ezinzima zingatshintshwa ukubuyisela ukusebenza.
Ukongezelela, imingxuma emincinci kwi-drill bit idibanisa kwiziko elingenalutho lentonga yokubhoboza, enika i-air passage. Xa kugrunjwa, i-debris yamatye iyenziwa, kwaye ukuba ayisuswanga ngexesha, i-bit iya kuphinda igubungele ilitye, ukunciphisa kakhulu ukusebenza kakuhle. Oku kwandisa ukunxiba kwi-bit kwaye kunciphisa ubomi bayo. Ngoko ke, umoya woxinzelelo oluphezulu kufuneka usetyenziswe ukukhupha inkunkuma emngxunyeni. Intonga yokugaya incinci ngobubanzi kunomngxuma, idala i-gap ukukhupha i-debris.
Ngenkqubela phambili yetekhnoloji eqhubekayo kunye nophuculo kubuchule bemigodi, i-roller bit drilling rigs, ngakumbi abo basebenzisa.Amasuntswana e-Hard Rock TriconekwayeAmasuntswana aManzi e-Tricone, banyanzelekile ukuba baguquke babe ngoomatshini abanobuchule ngakumbi, abakrelekrele nabangenabungozi kokusingqongileyo. Siyayikholelwa loo ntoAmasuntswana eSoft Rock Triconekunye nezinye iinguqulelo ziya kudlala indima ebaluleke ngakumbi kwimisebenzi yemigodi yexesha elizayo, ekhokelela kwiimpumelelo eziphawuleka ngakumbi.
