Electromechanical combination drive rigs

Specifications

1)      An electromechanical composite turntable rig an independent AC variable frequency motor drives, drawworks, drilling pump mechanically driven rig. Applicable 114m drill pipe, drill 4000-7000m deep oil, gas, wells.

2)      Drawworks and drilling rigs pump hydraulic transmission, the overall chain box unified driver program . After the diesel hydraulic coupling gear box unit through 6 are cars and car gearbox and shaft drive, cardan shaft are driven by two drilling pumps and car winch gearbox output and the input shaft using universal docking drive through V -belt drive automatic air compressors , energy generators. Furnished room equipment installed on the 0.8m high pedestal.

3)      Two auxiliary diesel generators and generator power grid power supply + energy.

4)      The main drawworks brake with hydraulic disc brakes, using Eaton brake ( or electromagnetic eddy current brake ) as auxiliary brake , centralized control , electric gear for automatic drilling and emergency driving .

5)      The turntable by AC inverter motor gear box through a chain -driven, variable speed, high torque and can meet the high speed drilling requirements.

6)      For the K -type derrick structure, located in the base of the foot base, good stability, the overall use of drawworks power lifting , installing 500 tons to meet the requirements of top drive unit.

7)      Respectively rig base and spin- liter boxes stacked structure, major rig components and equipment assembled in the low use of force as a whole hoisting drawworks.

8)      Rig equipped with variable frequency (VFD) system with MCC, VFD for AC inverter motor control dial and automatic drilling, MCC control rig for other electrical equipment.
