  • Patent number: 10288549
    Abstract: Systems and methods for detecting a layer-to-layer transition of a lifting steel wire rope on a reel are described. The system includes a reel assembly for winding a steel wire rope on a reel and a tensioning assembly for tensioning a segment of said steel wire rope. The system further includes a loading assembly and a lead screw sliding assembly. The loading assembly provides a vertical loading to the tensioning assembly so as to generate a loading force between the tensioned steel wire rope and the steel wire rope wound around the reel. The lead screw sliding assembly drives the tensioning assembly so as to move on a horizontal guide rail to generate a relative displacement between the tensioned steel wire rope and the steel wire rope wound around the reel. The tensioning assembly is connected to the loading assembly via a first threaded rod and a static torque sensor.

  • Patent number: 8814133
    Abstract: An automatic speed searching device for a partial stroke test of a control valve includes a spool valve operatively connected to a pilot valve and a blocker valve. An electrical module is operatively connected to the pilot valve, a supply of control fluid, and the blocker valve. In an open position of the spool valve, a first control fluid inlet is fluidly connected to a first control fluid outlet, and in a closed position of the spool valve the first control fluid outlet is fluidly connected to a second control fluid outlet. A method of determining an optimum stroke speed includes iteratively powering a main and secondary solenoid in the electrical module and updating parameters to move a control element of the control valve until movement of the control element is within a desired range.

  • Patent number: 8800360
    Abstract: An ECU determines whether condensed water is present at a rotor and vanes based on an electric current, which flows in an electric motor that drives the rotor. When the condensed water is determined to be present, the ECU drives the motor for a predetermined time period. When the condensed water is determined to be absent, the ECU stores a pressure, which is sensed through a pressure sensor, as a first pressure. The ECU is adapted to sense an abnormality in a pump characteristic based on a value of the first pressure.

    Abstract: A method and apparatus for measuring stem nut wear in a valve having a threaded valve stem that is positioned to engage the threads of a stem nut. In a preferred embodiment, a tool is mounted on the stem nut, wherein the tool rotates when the stem nut rotates. The tool indicates a measurement of stem nut rotation. An indicator indicates stem movement. The stem nut is rotated and the amount of percent wear is observed. Rotation continues until the stem begins to move. The tool provides a reading when the stem begins to move that indicates an amount of stem nut wear.

  • Patent number: 8720267
    Abstract: A system for on-line testing of an emergency shut-off valve includes a first emergency shut-off valve (first valve) and a flow control valve (second valve), with the system being configured to allow the second valve to serve as a combination flow control and second emergency shut-off valve. A subsystem is also provided for testing the first valve without fully closing the first valve in response to a signal from the control. In this subsystem, a solenoid valve bleeds off pressurized fluid to move the first valve from a fully opened to a partially closed position. A bypass around the second valve allows it to be tested as the second emergency shut-off valve, allowing the second valve to close completely without shutting down the process. The use of the two emergency shut-off valves in series wherein either valve can shut down the process provides a level 3 safety integrity level.

    Abstract: A test rig for testing blades for a wind turbine includes a fixing structure where a root end of a wind turbine blade can be fixed, a loading mass structure extending from the fixing structure, and an actuation structure which can apply a sinusoidal force to the loading mass structure so that a counterbalanced resonance is established between the loading mass structure and a blade which is fixed in the fixing structure. Due to the counterbalanced resonance, the force from the test rig onto the floor or other building components can be reduced relative to that known from the traditional rigs for blade testing.
