Hydraulic Power Swivel for Drill String Rotation
This equipment is applicable to assembly/disassembly of long and single drilling rods without using spinning chain, pipe wrench and Kelly spinner and, by reducing the startup/shutdown times of drilling rig, this product can help improve the efficiency of drilling rig and reduce the wear of pump, winch and other drilling equipment.
This equipment is configured with closed circuit hydraulic system, of which remote hydraulic control operating device is equipped with hydraulic control proportional handle in order to adjust the flow and direction of hydraulic oil. Its central pipe can realize stepless speed change of revolving speed.
This equipment also covers the functions as common swivels. While central pipe enters revolving or static state, drilling fluid will enter the drilling rod through goose neck, wash pipe and central pipe for circulating.
