Product Description
New Varco Top Drive 500 tons rated at 7500psi Electric Model TDS-11SA with VFD Pkg complete, comes with pipe handlers model pH-75, motor housing, on board hydraulic power unit, roller style carriage, bail, integral swivel with goose neck and 7500 psi "S-Pipe" assembly, and a shipping storage skid, drilling fluids path pressure is 7500 psi. The unit comes equipped with a 7500 psi wash pipe assembly, rotary hose rating, two forced air cooled 400HP AC drilling motors (800HP total) a 10.5: 1 double reduction helical, quiet gear drive, hydraulic disk brakes, powered rotating head, counter balance and stand jump. Ready for deployment to rig site when delivered.
The AC drilling motors
The TDS-11SA uses two 400 or two 350 HP AC motors mounted vertically side by side on top of the main body to power the TDS-11SA.
The modified D-face attaches the drilling motors to the main body. This mounting method allows installation of the drilling motors without shimming or special alignment. Each motor has a double ended shaft with a drive pinion mounted on the lower end and a disc brake rotor mounted on the upper end. Two hydraulic caliper disc brakes, mounted to the top end of each motor, hold torque in the drill string and assist in positioning during directional work. An electrical solenoid valve remotely operates the hydraulic caliper disc brakes.
The AC drilling motors are an open-frame type, meaning that the cooing air passes through the inside of the motor. The drilling motors, manufactured specifically for top drive applications, have internal temperature sensors, vacuum varnish impregnated windings, high capacity bearing, and tapered output shafts to improve serviceability of the pinion gear and brake hubs.
The motor cooling system on the TDS-11SA is a local intake pressure blower type. It consists of two 5 HP AC motors integrally mounted on top of each AC drilling motor. Air is drawn in from the combination brake cover/air intake and delivered through rigid ducting to an opening in the top of each motor. The cooling air then passes through the inside of the open-frame type AC drilling motors and exits out of louver opening near the bottom of the motors.

TDS is one of the greatest technological revolutions of petroleum equipment which is used to replace Kelly and rotary table. TDS can drill with triples instead of singles which can reduce two-thirds volume of work of makeup and breakout and greatly increase drilling speed. The advantages of TDS is that in tripping if meets block up or struck, you can rotate the drill string while circulating mud flow so it can reduce drilling accidents. TDS can increase the level of mechanization of operation together with the wellhead system which can reduce the worker's labor intensity and the amount of operators. Especially in the directional well and cluster well, TDS has more advantages.

Characteristics:

Drilling tools can be hoist at any time and well bore can be cleaned during drilling to reduce accidents. In tripping if meets block up, you can connect the drill string quickly and circulate mud and make back reaming so that it can reduce sticking accidents.

Integrated with mechanic, electric and hydraulic control system. The AC output parameters of frequency converter match with the performance requirement of motor. The self-designed PLC program is simplified which can be designed according to the requirement of customer. It has the function of protection and interlock, which is more suitable to the drilling condition.

The rotating head has two oil channels to supply oil to the tilt hydro cylinder to realize the forth tilt and back swing of link. Each oil channel is with dual seal for oil leaking accident reduced greatly and improving the reliability of system. When tripping operation, rotating head can rotate with drilling tools and it is easy to handle drilling accidents.

Adopt the plug-in type housing structure, the back-up tong and IBOP hydro cylinder don't rotate with the rotating head and the structure is simple.
Adopt double load path: When drilling operation, the bearing of gearbox bears the load. When tripping operation, the bearing of rotating head bears the load. It can greatly increase the service life of bearing and main shaft.
