摘要： A sliding vane, positive displacement pump is provided which includes a dual mechanical seal that protects against leakage from a pump chamber while also reducing slip across rotor end faces. The dual mechanical seal may be formed as a cartridge seal that is readily demountable from the pump for replacement and service, and is retrofittable to existing pumps to improve the performance thereof. The pump may integrally include a dual mechanical seal, or the mechanical seal assembly may be provided for use by itself or in combination with a replaceable head ring that can be installed on existing pumps for repair thereof or for a retrofit upgrade of such existing pump.

摘要： The present invention is a tubing centralizer for use within casing within a wellbore. The tubing centralizer has a tubing centralizer cage comprising a top ring, a middle ring, and a bottom ring and a plurality of springs, where each spring connects the top ring to the middle ring and the middle ring to the bottom ring and where each spring has a double arcuate shape such that the springs arc radially outward between the top ring and the middle ring and again between the middle ring and the bottom ring. The springs may be sized such that they exert outward pressure against the inside wall of the casing such that the tubing centralizer resists movement along the casing. The tubing centralizer may further comprise a tubing centralizer mandrel, where the tubing centralizer mandrel is part of the tubing string and extends through the tubing centralizer cage.

摘要： A test probe assembly includes a first elongate electrically conductive plunger that extends from a proximal first plunger end to a distal first plunger end, and is defined in part by a central longitudinal axis. The first plunger has a first spring latch at the distal first plunger end. At least a portion of the first plunger has an arc with a first plunger outer contact point opposite the first spring latch relative to the longitudinal axis. The first plunger is disposed in a spring. The first plunger outer contact point in contact with the inner diameter of the spring, and the first spring latch engages at least a portion of the spring. A method includes disposing a first plunger within a spring along a spring longitudinal axis, disposing a second probe within the spring along the spring longitudinal axis, and engaging the spring latch and the second plunger spring latch with the spring, for instance by capturing an end coil of the spring with the spring latch of at least one of the spring latch or the second plunger spring latch.

摘要： A method of determining the thermal status of fuel in a fuel distribution system (10) includes pressurizing the distribution line (16) by activating a submersible pump (14) in an underground storage tank (12). Once the distribution line (16) is pressurized, the pump (14) is switched off, and the reverse flow rate out of the distribution line back into the tank (12) is monitored. The test is repeated after a period of time, and the reverse flow rates of the separate tests are compared to determine if the fuel in the distribution line (16) is in thermal stability with the surrounding environment based on flow rate changes between tests.

摘要： A material handling system (10) has a vacuum cup assembly (14) engagable with an object (20) and movable to move the object using a pressurized air source (12), a vacuum cup (16), a venturi device (18) and a vacuum valve (24) and auto-release valve (26). The venturi device (18) is in fluid communication with the vacuum cup (16) and connected to the supply line (28) so that pressurized air can be supplied to and through said venturi device to generate a partial vacuum when the perimeter seal of the vacuum cup is engaged with the object surface. The vacuum valve (24) may open and close the supply line at a location upstream of the venturi device in response to a pressure level at the vacuum cup cavity. The auto-release valve (26) may vent the vacuum cup cavity to atmosphere in response to reduced pressure in the supply line at a location upstream from the vacuum valve (24).
