    摘要: A rotating machine having a rotor comprising a flexible shaft with a plurality of masses distributed along the shaft. Included within these masses are magnetic disks. Magnetic bearings are attached to the housing and coact to support the rotor in only a radial direction or in both radial and axial directions. Bearing sensors are used to measure the shaft position local to each bearing relative to a face of each bearing. Variable magnetic bearing parameters are controlled so as to change values of stiffness and damping of the magnetic bearings in response to the measurements from the bearing sensors. These controls can be direct analog circuitry, or digital components, or a combination of digital and analog components.

    摘要: A magnetic bearing system includes a rotor with a plurality of masses distributed along the shaft including a portion having a circular peripheral surface suspended radially from pole pieces of permanent and electromagnets. A fault tolerant adaptive system responds to detected parameters of the rotor for varying the stiffness and damping the rotor. Position and speed of rotor are sampled at a rapid rate for each of a plurality of control axes and are processed independently during each sampling period. Malfunction of any of the processors causes supervisory controller to reconfigure the processing of the samples.

    摘要: A seal for use in temperature and pressure extremes is disclosed. It features springs internal to the sealing members and the ability to seal against pressure differentials from opposed directions. A spacer ring prevents contact from oppositely oriented seal components and at the same time prevents spring and seal collapse under extreme loading conditions. The seal assembly is self-centering in a downhole seal bore and can be used on tools delivered on wireline, where the insertion forces available are at a minimum. The seal can withstand pressure differentials in excess of 13,500 PSI and temperatures above 350 degrees Fahrenheit.

    摘要: A dust proof electric switch is provided for use in a dynamoelectric machine employing a centrifugal acuator having a terminal board with a cup formed therein in which a fixed contact point and terminal are mounted. A pivotable switch arm having a contact point attached thereto is mounted to the arm and extends above and cantilevered across the terminal board so that pressure on the switch arm from the centrifugal acuator causes the contact points to touch thereby closing the circuit. An open ended, resilient, flexible boot is affixed to the cup and extends upward between the terminal board to snuggly abut the switch arm and completely enclose the contact points when they are touching and when they are apart thereby protecting the contact area from dust and debris as well as containing sparks within the boot. The terminal board contains stops which serve to maintain alignment of the switch arm.

    摘要: A terminal board for a dynamoelectric machine is mounted to an end-shield of the machine. The terminal board has securing means for fixing an electrical switch to the terminal board using a single conventional fastener. A second snap-in arrangement is provided in place of additional fastener. The terminal board includes an arm spaced from the fastener hole. The arm is spaced above a surface of the terminal board and defines a slit with the terminal board through which an ear of the switch extends. A finger extends down from a free end of the arm to define a stop which maintains the switch ear in the slot. The finger and the single fastener together fix the switch to the terminal board.

    摘要: A dynamoelectric machine (10) has no external leads. A stator assembly (12) includes at least one set (14) of electrical windings (16) terminable at each end. A rotor assembly (18) includes a rotatable shaft (22) and the stator and rotor assemblies are installed in a housing (24). A terminal block (38) is internal of the housing and the ends of the winding set are terminated in this block. The housing has an opening (114) therein through which the termination unit is accessible. A receptacle (102) to which external electrical wires (W1, W2) are connected is matingly connectable to the material block through the opening to connect the machine to the external electrical wires.

    摘要: An electric cable joint (including a termination) comprises at least one inner component heat-shrunk onto a cable or on to at least one part of a cable and at least one outer component of resilient material which is an interference fit with the inner component(s). The heat-shrink component takes up considerable variation in the size of the underlying cable (or part thereof) so that a range of cable sizes can be accommodated by a much smaller number of inner component sizes than in a purely "slip-on" range.

    摘要: Concentric control lines have an outer line disposed about one or more inner lines. Encapsulated together, the lines only require one penetration through the wellhead to extend downhole. At the wellhead, the lines communicate with an operating system, which can provide hydraulics, electric power, signals, or the like for downhole components. Beyond the wellhead, the concentric lines extend along the tubing to a manifold. The outer line sealably terminates at the manifold's inlet, while the inner conduit passes out an outlet with a sealed fitting to connect to a downhole component. A downhole line couples to an outlet of the manifold and communicates internally with the outer conduit terminated at the manifold's inlet. This downhole line can then extend to the same downhole component or some different component.
