Product Details:

A rotary desk is the revolving plate at the rig's drill ground that turns the drill string in a clockwise course. The rotary table surrounds the 4 or six-sided kelly bushing and kelly force to which the drill string is hooked up, moving the strength from the rig's force device to the drill string and bit.

The rotary table hyperlinks the rig's strength deliver to the drill string, it may be described as a capture. most rigs have a rotary desk due to the fact the top mover for the drill string, however, top strength structures that permit continuous rotation of the drill string have changed the rotary desk, the kelly bushing and the kelly strain in a few rigs, because of changes in trenchless construction requirements.

The rotary force table is familiar in pinnacle-pressure rigs, that is, those who have their pressure motor at the top of the rig. Drill string sections are first linked to the bottom hole assembly. As drill string sections bypass into the bore, extra sections of drill string are connected to the pinnacle strain motor and to sections inside the bore, constructing the drill string from the top. the ones sections of drill string screw collectively the usage of a clockwise movement. The rotary desk -- which turns clockwise -- is used to tighten the segments of the drill string.
