Abstract
An annular tube (or other shape) of elastomeric cellular material comprising elastomeric closed cells having gas infused therein is supported by structures protruding from the bottom surface of a suction stabilizer's head and/or by structures within the interior volume of the annular body of the suction stabilizer, preferably with spacing between the outer diameter of the annular tube of the cellular material and the inner walls of the suction stabilizer body. The gas-infused closed cell material may thus be employed in new suction stabilizer or pulsation dampener or to retrofit existing suction stabilizers or pulsation dampeners designed for a gas-filled bladder.
Claims24
A cellular part for a pulsation control device, the cellular part comprising:
- a head configured to attach to and seal an opening at an upper end of a body for one of a suction stabilizer or a pulsation dampener;
- and
- an annular tube comprising cellular material for mounting within an internal volume of the body, the annular tube secured to a bottom of the head at a first open end of the annular tube and configured to hang within the internal volume of the body with a second open end of the annular tube spaced apart from a bottom surface of the body.
A method of fitting or retrofitting a pulsation control device, the method comprising:
- attaching a head configured to seal an opening at an upper end of a body for one of a suction stabilizer or a pulsation dampener to the upper end of the body;
- and
- mounting an annular tube comprising cellular material within an internal volume of the body by securing the annular tube to a bottom of the head at a first open end of the annular tube to hang within the internal volume of the body, with a second open end of the annular tube spaced apart from a bottom surface of the body.
