Product description
Drawwork is the core part of drilling rig. It is mainly used for feeding drilling tools,lifting or laying down mast, triping in and out drilling pipe, running in casing operation and so on.
Technical Features
Electric single shaft drawwork:It is composed of the AC or DC motors, gear reducers, hydraulic disc brake,the drawwork frame,the drum shaft assembly, automatic bit feed equipment and drawwork control system.Compare with the similar drawwork, the parts are few, the volume is small, the weight is light; The drum shaft is driven by a DC electric motor or a AC-VFD electric motor through the gear reducer(It is also possible that two motors drive gear reducer), which may realize the smooth velocity modulation in the o~140Hz scope. Use the two-stage speed gear reducer transmission, the transmission efficiency is high, the vibration is small, the noise is low, the service life is long.Main brake is hydraulic disc brake, auxiliary brake is dynamic brake or EATON brake.The drum is equipped with Lebus rope groove,has the independent digital conntrol AC-VFD and the computer automatic control system. Which may realize automatic bit feed.Trip-in operating and drilling are monitored and analyzed on the real-time, which realize the best drilling.
■DC motor drive chain drawwork:It is driven by DC motor, has dividing type or integral-type structure; The drum high speed end, the drum low speed end are equipped with the ventilated pneumatic tube clutch. Main brake is hydraulic disc brake, auxiliary brake is electromagnetic eddy current brake.Adopt the air control gears shift, the chain drive structure. Chain lubrication is thin oil,bearing lubrication is grease/The drum is machined with Lebus rope grove.Drawwork can be equipped with automatic driller device.
■Mechanical drive drawwork:The drum high speed end,the drum low speed end are equipped with the ventilated pneumatic tube clutch.The brake rims(or brake disc) is forced to be cooled by circulating water, intermediate frequency quenching is applied to the brake rims(or brake disc)surface, which make the drum wearing resistance good and service life long.Main brake is hydraulic disc brake or band brake,auxiliary brake is electromagnetic eddy current brake or EATON brake (water-cooled or air-cooled).All teeth gear shift clutchs are the involute spline teeth clutch, the gear shift is the air cylinder or the pneumatic tube clutch,easy. Simple and reliable to operate.The drum is machined with Lebus rope groove. Drawwork can be equipped with automatic driller device.
