摘要:
A progressive cavity type motor or pump including a stator insert with a reinforcing agent dispersed in a manner to improve properties of the stator insert. The reinforcing agent may be a fiber, nanotube, metal, ceramic, or polymer. A dispersing agent may be used to obtain a homogenous distribution. A magnetic reinforcing agent may be incorporated into a stator insert. The stator insert is subjected to a magnetic field to orient the magnetic reinforcing agent in a particular orientation. The magnetic field may also reposition the magnetic reinforcing agent within the stator insert. The stator insert may be formed by injection molding, transfer, or compression molding among other methods.
摘要:
A method to manufacture a blowout preventer seal including disposing at least one insert and at least one elastomeric material in a mold, heating the mold to a cure temperature, curing the at least one elastomeric material, measuring a temperature of the at least one elastomeric material during the curing, adjusting a cure time and the cure temperature based on the measured temperature of the elastomeric material, and removing the cured blowout preventer seal from the mold.

摘要:
A packing unit for a blowout preventer includes an elastomeric, annular body configured to be disposed about a longitudinal axis of the blowout preventer and configured to be displaced radially inward towards the longitudinal axis upon actuation of the blowout preventer. The elastomeric, annular body includes a first section having a first set of material properties and a second section having a second set of material properties. The packing unit includes a plurality of rigid inserts distributed at equal radial distances from each other within the elastomeric annular body and about the longitudinal axis of the blowout preventer.
摘要:
A method of increasing the crosslink density of a seal for a blowout preventer that includes selectively applying electron beam radiation to a selected portion of a blowout preventer seal comprising a cured elastomeric material and at least one rigid insert to increase the crosslink density of the selected portion of the cured elastomeric material is disclosed. Methods of curing a seal for a blowout preventer, blowout preventers, and seals for blowout preventers are also disclosed.
