Big Torque Rotary Hydraulic Breakout Unit Downhole Motor Thread Connection

Hydraulic Breakout Unit, Downhole Motor Thread Connection Make Up and Break Out Unit

Hydraulic breakout units with six radial cylinders and double sliding arms is designed for workshop to make up and break out thread connection of down hole motor. Rotating and sliding chuck are both adjustable clamping cylinders, fix and clamp workpiece by chuck body and tong. Sides plates of sliding chuck link together with chuck body in bearing base and through end flange to achieve limitation. There are rotating orbit, draw tool orbit and faster screwing tool. Faster screwing is achieved by conducting rod position, double clamping and four friction wheels. Thus, it is convenient to make up or break out the drilling motors and reduces labour strength as well as raises productivity by completing screwing, spinning and drawing at the same time.

Specification

Hydraulic console mainly consists of two parts: power system and hydraulic system. Power system includes electric motor, piston pump, vane pump, shaft coupling and base plate, while hydraulic system includes oil tank, integrated assembly, hydraulic valve and flow lines.

Not only does the rotating chunk clamps the drilling motors, but also provides break-out and make-up torque during spinning. At the same time, the sliding chunk plays a role in clamping and fixing the drilling tools when drawing rotor. It mainly consists of chuck body, clamping cylinder, clamping tong. Plywood, flange, tong rod and spinning cylinder. At working time, sliding cylinder drives chuck body’s rotating by rotating shaft transmitting the torque to tong rod. In addition, clamping tong connected with cylinder rod is used to clamp the drilling tools, while lateral plywood and flange match with chuck body to realize rotating and axial position. When spinning, start oil cylinder and drive tong to clamp drilling tools firstly, then start sliding cylinder to make tong move so as to achieve spinning.

Sliding chuck is used to clamp drilling tools and bear reverse torque when spinning during tightening or loosing the button, while allows axial movement between two joint ends of the drilling tools happened in the time of spinning. Besides, it can meet different clamping distance needs away from sliding chuck, chunke body, clamping cylinder, chuck tong, plywood and plan wheels, etc. form the rotating chuck, self-lock function and flow valve are possessed by the six clamping cylinder to finish all cylinder’s driving at the same time by adjusting the flow.
