China Setsi sa ho Cheka Oli Bahlahisi
Ka nts'etsopele e tsoelang pele ea tlhahiso ea ho cheka, maemo a ts'ebeliso ea lisebelisoa tsa ho phunya a fetohile a mangata le ho feta, 'me mefuta e sa tšoaneng ea lisebelisoa tsa ho phunya e hlahile ka tsela e nepahetseng. Lintlha tse amang mofuta le sebopeho sa lisebelisoa tsa ho cheka li kenyelletsa mokhoa oa ho cheka, botebo ba ho cheka, boholo ba sekoti le boholo ba lisebelisoa tsa ho phunya, le maemo a sebaka sa ho cheka (joalo ka motlakase kapa mafura, lipalangoang le maemo a leholimo).
1. Ho latela mokhoa oa ho phunya
(1) Lisebelisuoa tsa ho cheka tse nang le tšusumetso, joalo ka lithapo tse nang le tšusumetso ea terata (lisebelisoa tsa ho cheka), lisebelisoa tsa ho cheka tse thothomelang, joalo-joalo.
(2) Lisebelisoa tsa ho cheka ka rotary, tse kang tse sebelisoang ha ho cheka ka rotary.
(3) Lisebelisoa tsa ho phunya matla a Downhole, joalo ka lisebelisoa tsa ho phunya ka rotary, lisebelisoa tsa ho phunya li-turbo, lisebelisoa tsa ho phunya li-screw, lisebelisoa tsa ho cheka tsa motlakase, joalo-joalo.
2. E arotsoe ka botebo ba ho cheka
(1) Mochine oa ho cheka seliba se tebileng haholo. E nka mochine oa ho phunya o bophara ba phala ea ho phunya 114 mm, bophara bo tebileng ba ho phunya bo fetang limithara tse 7000, le boima ba hook bo fetang 4,500 kN.
(2) Mochini oa ho cheka seliba se tebileng. Molamu oa ho phunya o bophara ba 114 mm, botebo ba ho phunya ka lebitso ke 4000-7000 metres kapa ho feta, 'me boholo ba hook e boima ke 2250-4500 kN kapa ho feta.
(3) Lisebelisoa tsa ho cheka liliba tse mahareng le tse tebileng. E nka mochine oa ho phunya o nang le bophara ba phala ea ho phunya limilimithara tse 114, bophara ba ho phunya bo tebileng ba limithara tse 1500-4000 kapa ho feta, le palo e kholo ea hook ea 900-2250 kN kapa ho feta.
Tse tharo, ho latela lisebelisoa tsa motlakase

(2) Sesebelisoa sa ho cheka se tsamaisoang ke AC, se loketseng ho sebelisoa masimong a oli a nang le marang-rang a matla a indasteri.
(3) Motlakase oa ho phunya o tsamaisoa ke motlakase o tobileng, 'me mochine o sebetsang o tsamaisoa ke motlakase o tobileng.
Ea bone, ho ea ka mokhoa oa ho khanna
(1) Khanna u le mong. Mochini o mong le o mong o sebetsang o tsamaisoa ke lijenereithara tsa boholo bo fapaneng, tse sebelisoang haholo bakeng sa koloi ea motlakase. Phetiso e bonolo ebile e bonolo ho e kenya, empa sekhahla sa tšebeliso ea matla se tlase mme boima ba thepa eohle bo boholo.
(2) Koloi e kopaneng. Likarolo tse tharo tse sebetsang tsa li-drawworks, pompo ea ho cheka le turntable li tsamaisoa ke yuniti e le 'ngoe ea matla. Lisebelisoa tse ngata tsa ho cheka li sebelisa morero ona. Koloi e kopaneng e ka boela ea kenyelletsa pompo e le 'ngoe feela ea ho phunya,' me pompo e 'ngoe ea ho phunya e tsamaisoa ka thoko. Mochine o kopantsoeng oa ho cheka o na le tšebeliso e phahameng ea matla 'me e ka fetoloa ka bobeli ha enjene e hlōleha, empa phetisetso e rarahane, ho kenya le ho lokisa ho thata,' me katleho ea phetisetso e tlaase.
(3) Ho khanna ka sehlopha. Motsoako oa matla o pakeng tsa drive ea motho ka mong le drive e kopaneng. Ho na le likhetho tse peli bakeng sa mechini e meraro e sebetsang. Sekhahla sa tšebeliso ea matla ea mofuta ona oa ho cheka sekontiri se phahame ho feta sa koloi e le 'ngoe,' me tekanyo ea phetisetso e bonolo ho khanna ka mokhoa o kopanetsoeng. Lihlopha tse peli tsa mechine e sebetsang le tsona li ka kenngoa libakeng tse phahameng tse fapaneng le libaka tse hasaneng.
