| 20100202906 | Safety Clamp for Walking Beam Compressor - Various methods and devices are provided for securing a walking beam compressor to a walking beam. In general, the walking beam compressor is a gas compressor unit that can be disposed around a piston rod extending from a walking beam of an oil well. The piston rod can be coupled to the walking beam by a securing mechanism that engages both the piston rod and the walking beam to prevent the piston rod from disengaging from the walking beam during rocking movement of the walking beam. | 08-12-2010 |
| 20090246049 | COATED CYLINDER FOR WALKING BEAM COMPRESSOR - Various methods and device are provided for use in a walking beam compressor used in an oil well pump. In one embodiment, a walking beam compressor assembly is provided having a compressor configured to receive and compress gas. The compressor can be positioned around a piston rod movably disposed therethrough and can include a cylindrical housing having an interior surface that is coated with a self-lubricating composite material. The self-lubricating composite material can be impervious to gas such that it protects the interior surface of the cylindrical housing from corrosion by the gas. In one embodiment, the self-lubricating composite material can be a nickel ceramic composite. The cylindrical housing can be formed of any suitable material known in the art able to withstand pressure and heat within the housing, for example, a metallic material. | 10-01-2009 |
| 20090246037 | SAFETY CLAMP FOR WALKING BEAM COMPRESSOR - Various methods and devices are provided for securing a walking beam compressor to a walking beam. In general, the walking beam compressor is a gas compressor unit that can be disposed around a piston rod extending from a walking beam of an oil well. The piston rod can be coupled to the walking beam by a securing mechanism that engages both the piston rod and the walking beam to prevent the piston rod from disengaging from the walking beam during rocking movement of the walking beam. | 10-01-2009 |
| 20090243223 | STUFFING BOX FOR WALKING BEAM COMPRESSOR - Various methods and devices are provided for use in a walking beam compressor used with an oil well pump. In general, an injectable fibrous sealant is provided for use in a stuffing box to form a seal around a piston rod that couples to a walking beam for pumping oil out of the ground. The injectable fibrous sealant can be configured to form a gas tight seal around the piston rod, while allow reciprocal longitudinal movement of the piston rod therethrough. The injectable fibrous sealant is particularly advantageous as it has an extended life, eliminating the need to replace the seal, and repairs can be performed on-site by injecting additional sealant into the stuffing box. | 10-01-2009 |
