Molao-motheo oa ho sebetsa oaReverse circulation rig:
Seo ho thoeng ke "reverse circulation drilling rig" se bolela hore ha se sebetsa, diski ea rotary e tla khanna sekhahla sa ho phunya le ho pshatla lejoe le mobu ka sekoting, mokelikeli o phallang o tla phalla ka tlase ho lesoba ho tloha lekhalo la annular pakeng tsa phala ea ho phunya. 'me lerako la lesoba, le pholisoe karolo ea ho phunya, le jare lefika le mobu oa ho phunya slag e sehiloeng, ebe o khutlela fatše ho tloha mokoti oa lipeipi tsa ho phunya. Ka nako e ts'oanang, metsi a phallang a tla khutlela ka mokoting ho etsa potoloho. Kaha bophara ba sebaka se ka hare sa phaephe ea ho phunya se le senyenyane haholo ho feta sa seliba, metsi a seretse a phaepheng ea ho phunya a phahama ka potlako ho feta mokhoa o tloaelehileng oa ho potoloha. Hase feela metsi a hloekileng, empa hape a ka tlisa slag ea ho phunya ka holim'a phaephe ea ho phunya le ho phalla tanka ea seretse ea seretse, moo seretse se ka sebelisoang hape ka mor'a ho hloekisa.
Molao-motheo ke ho kenya phala ea ho phunya ka mokoting o tletseng mokelikeli o phophomang, 'me ka ho potoloha ha tafole ea rotary, khanna moea o thata oa sekoere sa phetiso ea molamu le karoloana ea ho phunya ho potoloha le ho khaola lejoe le mobu. Moea o hatelitsoeng o fafatsoa ho tloha molomong o ka tlaase oa phaephe ea ho phunya, ho etsa motsoako oa seretse, lehlabathe, metsi le khase e bobebe ho feta metsi a phaepheng ea ho phunya mobu le lehlabathe le khaoloa. Ka lebaka la phello e kopantsoeng ea phapang ea khatello pakeng tsa ka hare le ka ntle ho peipi ea ho phunya le lebelo la khatello ea moea, motsoako oa khase ea metsi a lehlabathe la seretse o tla phahama hammoho le mokelikeli o phallang, 'me o tla tšeloa ka har'a letamo la mobu kapa polokelo ea metsi. tanka ka hose ea khatello. Mobu, lehlabathe, lehlohlojane le lithōle tsa majoe li tla lula ka har'a letamo la seretse, 'me mokelikeli o phallang o tla phalla ka mokoting hape.
Likarolo tsareverse potoloho cheka rig:
1. Reverse circulation drill e na le letsoho la mochine le nang le pipe ea ho phunya, e ka sebelisoang ka sekoting se otlolohileng le maemo a manyenyane a vertex angle. Ka nako e ts'oanang, mochini oa ho cheka o boetse o na le winch e thusang ea hydraulic, e fokotsang haholo matla a basebetsi ba mochine, 'me e thusa mohahong o sireletsehileng le o tsoetseng pele oa mochine.
2. Mochine oa ho cheka o nka mochine oa boenjiniere le mochine oa ho tsamaea oa hydraulic, o bonolo ho tsamaea 'me o loketse lithota, lihlabe, maralla le mefuta e meng ea mobu. Chassis e na le li-outrigger tse 4, kahoo mochini oa ho cheka o na le thothomelo e tlase le botsitso bo botle nakong ea kaho ea ho cheka.
3. Reverse circulation drilling rig e tsamaisoa ke matla a motlakase, ka lerata le tlaase le tšilafalo, ts'ebetso e phahameng le coefficient e kholo ea polokelo ea matla.
4. Reverse circulation drilling rig e na le mesebetsi e mengata, 'me likarolo tsohle tsa bohlokoa ke lihlahisoa tse bolokang chelete e ngata. Sistimi e na le ts'ireletso ea khatello le lisebelisoa tsa alamo.
5. Lisebelisoa le lisebelisoa tsa li-activator tsohle tsa reverse circulation drilling rig li teng sethaleng sa ts'ebetso, se loketseng le se ka tšeptjoang bakeng sa ts'ebetso le taolo.
6. Reverse circulation cheka rig e nka foreimi e ikhethang ea ho phunya. Ts'ebetso ea ho cheka e kholo, khanyetso ea torsion e kholo, sebopeho se bonolo, tlhokomelo e bonolo, ho falla ho bonolo, ts'ebetso ea orifice e bonolo, 'me ho ka hahoa mochine o moholo oa vertex angle.
7. Reverse circulation drilling rig e nka hlooho e kholo ea matla e nang le mosebetsi oa ho hanyetsa tšusumetso e kholo. Lebelo la ho potoloha le loketse litlhoko tsa potoloho ea moea. Matla a phahamisang, torque le liparamente tse ling li ka fihlela litlhoko tsa 100M tse sa tebang tsa phepelo ea moea o ka morao ho DTH le litlhoko tse ling tsa ts'ebetso.
