Abstract
A tubular rotating system for rotating threaded tubulars is provided. The system includes a frame, a plurality of rollers coupled to the frame and configured to rotate a tubular, and a control valve coupled to the frame and configured to control a rotational speed of the rollers. The control valve controls an amount of air, fluid, or electric power supplied to the system based on tension applied to the system to thereby control the speed at which the rollers rotate.
Claims20
A tubular rotating system for rotating threaded tubulars, the system comprising:
- a frame;
- a plurality of rollers coupled to the frame and configured to rotate a tubular;
- and
- a control valve coupled to the frame and configured to control rotational speed of the rollers based on a tension force such that the rotational speed of the rollers increases as the tension force increases.
A tubular rotating system for rotating threaded tubulars, the system comprising:
- a frame;
- a plurality of rollers coupled to the frame and configured to rotate a tubular;
- and
- a control valve coupled to the frame and configured to control power supplied to the rollers, wherein the rollers are rotated at a first rotational speed greater than zero when the control valve is in an off state, and at a second rotational speed greater than the first rotational speed when the control valve is in an on state.
A tubular rotating system for rotating threaded tubulars, the system comprising:
- a frame;
- a plurality of rollers coupled to the frame and configured to rotate a tubular;
- and
- a control valve coupled to the frame and configured to control rotational speed of the rollers based on a tension force;
- wherein the control valve comprises a piston having a valve disposed in a body and a biasing member disposed in the body that applies a force to the piston;
- wherein the piston is configured to move from a first position where the valve allows only a portion of operating fluid flow through the body to a second position where the valve allows all of the operating fluid flow through the body when the biasing member is compressed by the tension force;
- and
- wherein the rollers are rotated at a first rotational speed when the piston is in the first position, the rollers are rotated at a second rotational speed when the piston is in the second position, and the first rotational speed is less than the second rotational speed.
