Power Swivel

    The TDS Workover System is not only used for casing milling, milling, drilling cement plugs, bridge plugs, fishing and other workover operations, but also for sidetracking, drilling open hole wells and core drilling operations. It can be directly connected to single or dual pipes. The advantages of this system include stable main shaft movement, powerful torque output and convenient operation. It can also help to reduce NPT, improve work efficiency and reduce operating costs effectively.

    With a compact design, it can be applied on majority of shallow well derricks or workover derricks. The main shaft is directly driven by a hydraulic Motor without transmission gears, making the transmission reliable and easy to maintain. It is powered by a high-torque radial piston Motor, featured as small in size and large in torque. A closed-loop hydraulic system is adopted, and the torque and speed are of stepless adjustment within the specified range; the main bearing inside the casing adopts oil-immersed lubrication, which can provide sufficient lubrication and has cooling function, with a compact and reasonable structure; the pipeline winch traction winch has its cooling and oil replenishment functions isolated from each other to avoid mutual interfere, thus their rESPective independence and mutual reliability are increased.
