Description
The swivel is an intermediate link between talevy system and the rotating boring tool.
When drilling wells the swivel provides a possibility of free rotation of the boring tool with a simultaneous supply of flushing liquid in a column of boring pipes.
High dynamic loading capacity for such class of swivels provides its reliability at the heaviest modes of rotor drilling.
The increased opening through passage in a trunk reduces hydraulic resistance when pumping drilling mud fluid.
The increased length of a trunk of the swivel allows to cut pyatikratno a new carving instead of failed, thereby, increasing the term of its service
