DSL85 Power Swivel for Workover Rig

DSL85 power swivel is applicable to connect and disconnect long single drill pipe and oil pipes, without the use of spinning chain, pipe wrench and Kelly spinner. The use of power swivel to connect and disconnect drill pipes and oil pipes is able to reduce number of times the rig stops/starts, thus improving the rig efficiency and reducing wear of pumps, winches and other rigs.
DSL85 power swivel adopts a closed-cycle hydraulic system, which controls flow direction of the hydraulic oil through a hydraulically-controlled handle, and regulates diesel engine speed to realize speed change of swivel through a diesel engine remote control rotary knob, thus realizing infinitely variable speeds of central pipe of the power swivel.
DSL85 power swivel has functions of an ordinary swivel, when the central pipe rotates or is still, the drilling fluid may enter inside of the drill pipe through gooseneck, wash pipe and central pipe for drilling fluid circulating.

DSL85 power swivel contains two parts, YSL85 hydraulic swivel and DKYC180/31.5Y power control unit, all the components are installed on the entire skid and constitute a sturdy and lightweight device.
DSL85 power swivel is characterized by:
1) It provides smooth, shock-free torque to reduce damage to the drill stem;
2) It applies to most drilling wells and workover derricks;
3) It allows to use long drill stem;
4) It can replace the traditional swiveling swivel;
5) It is installed on the skid in an integral way to facilitate transportation.
