VFD Skid-Mounted Drilling Rig
Tlhaloso:
Mud Pump e tsamaisoa ke li-motor tsa VFD AC tse behiloeng holim'a skid e le 'ngoe, e nang le phetiso ea V-belt le sebopeho se bonolo.
Tafole ea rotary e tsamaisoang e ikemetseng e matha ka lebelo le tlase ho 1 + 1R / 2 + 2R, 'me phetoho e tla lemohuoa ka phetoho ea koloi ea AC.
Ho sebelisoa theknoloji ea ho khanna ea AC-DC-AC, tafole ea rotary le Drawworks li sebetsa ka li-quadrant tse 'ne le taolo e felletseng ea vector ea dijithale.
Dynamic brake e amoheloa ho nkela brake ea eddy hajoale e le brake e thusang.
Ho cheka ka othomathiki ho fumanoa ke enjene e kholo ea Drawworks kapa enjene e ikemetseng. Taolo ea boemo ba kelello bakeng sa boloko ba maeto e thibela li-crown block le tafole ea rotary ho thulana.
Puisano ea nako ea sebele le marang-rang li fumaneha ka ho sebelisa theknoloji ea PROFIBUS.
Mofuta oa mofuta oa K o loketse ho kenya sistimi ea Top Drive ea mofuta o fapaneng.
Sling shot kapa swing up substructure le mast li sebelisoa e le hore lisebelisoa tsohle li ka kenngoa sebakeng se tlaase
Tšebeliso e nepahetseng ea matla ka lebaka la matla a phahameng (bonyane 95%), Matla a phahameng a kamehla le ka lebelo le tlase.
Regenerative braking bakeng sa taolo e bolokehileng le e sebetsang ea li-drawworks.
Sistimi e bonolo le e bolokehileng ea ho cheka li-auto bakeng sa ho laola le ho laola liparamente tse joalo ka boima ba 'mele (WOB), sekhahla sa ho kenella (ROP), le taolo ea torque ea rotary.
