Abstract: A gas supply system for a mechanical seal turns on the gas supply at a pressurized flow rate at the time of compressor case pressurization and remains on during compressor rotation until pressure is adequate. The gas supply system has an intensifier that includes a pair of mechanically inter-connected pneumatic pressure cylinders which comprise a drive cylinder that affects movement of a boost cylinder wherein the displacement of these mechanically interconnected pistons in the drive cylinder and boost cylinder intensifies the pressure being discharged by the boost cylinder and supplied as a barrier fluid to the mechanical seal. The intensifier uses a control valve and operating system which includes a fast-acting 5/2-way solenoid valve having a feedback loop connected to a control system which includes a microprocessor that controls valve actuation.

Abstract: An electrical submersible pump system includes an electric motor operably coupled to a fluid pump which includes first and second fluid ports. The first and second ports are selectively operable as a fluid intake and a fluid discharge of the fluid pump with reversal of a direction of rotation of the fluid pump. Valves in the system are controllable to selectively direct fluid discharge of the fluid pump to an inflation volume of the inflatable packer and toward the surface in a wellbore tubing. The valves are further controllable to vent pressure in the inflation volume to deflate the packer.

Abstract: A system and method for rapidly and reliably sealing off a selected opening from the passage of smoke, noxious fumes, or contaminated air includes a powered clutch and viscous governor that provides a fail-safe mode of operation. A curtain is positioned in a housing adjacent to an upper limit of an opening such as a hoist access-way. The curtain is wrapped around a spindle that is connected to a spool via two cords. The curtain is held in the housing in a stored configuration by a powered clutch so that upon removal of power, either via a controller or by power loss, the clutch releases the spool allowing the cord to unwind lowering and thus deploying the curtain. A capacitor can be included to prevent inadvertent deployments due to momentary power loss. The speed at which the spool rotates, and correspondingly the curtain deploys, is limited by a viscous governor coupled to the spool.
