    摘要: A method includes controlling a bearing fluid supply system to provide the bearing fluid to a hydrostatic bearing of the turbopump assembly. The bearing fluid includes a supercritical working fluid. The method also includes receiving data corresponding to a pressure of the bearing fluid measured at or near a bearing fluid drain fluidly coupled to the hydrostatic bearing, determining a thermodynamic state of the bearing fluid at or near the bearing fluid drain based at least in part on the received data, and controlling a backpressure regulation valve to throttle the backpressure regulation valve between an opened position and a closed position to regulate a backpressure in a bearing fluid discharge line to maintain the bearing fluid in a supercritical state in the hydrostatic bearing and/or at or near the bearing fluid drain.

    摘要: A method of operating a wind turbine having a bearing assembly, a shaft received therein, and at least one sub-system capable of altering a dynamic state of the wind turbine includes monitoring at least one parameter indicative of a load on the shaft; comparing the at least one parameter to a threshold criteria; and when the at least one parameter meets the threshold criteria, altering the dynamic state of the wind turbine to reduce the load on the shaft; and/or altering the state of the bearing assembly to better accommodate the load on the shaft. A control system for the wind turbine includes a controller operatively coupled to the bearing assembly and the at least one sub-system, and at least one sensor for monitoring at least one parameter indicative of a load on the shaft. The controller signals the sub-system or the bearing assembly when the threshold criteria is met.

    摘要: A variable flow-rate hydrostatic bearing includes a variable flow-rate adjusting portion that reduces the flow rate of fluid and then introduces the fluid into a pocket. The variable flow-rate adjusting portion is configured such that a fluid supply chamber (32a) is separated from a fluid storage chamber (31a) having a projection (31b) by a leaf spring (33) that faces the projection (31b) with a predetermined clearance left therebetween, and the projection (31b) has an opening (31c) and a flow passage that is in communication with the pocket (2a). In the variable flow-rate hydrostatic bearing, a fixed orifice (33a) that provides communication between the fluid supply chamber (32a) and the fluid storage chamber (31a) is formed in the leaf spring (33) at a portion that does not face the projection (31b).

    摘要: A hydrostatic guide device includes: a fixed member (19) having vertical guide faces (16a, 17a); a movable member (14) having vertical slide faces (14a1, 14a2); a fluid supply device (33); a hydrostatic pocket (34) to which a first fluid pressure (P1) based on a dimension of a gap (L1) is applied, and that urges the movable member with a first urging force (F1); and a hydraulic pocket (35) to which a second fluid pressure (P2) based on a dimension of a gap (L2) is applied, and that urges the movable member with a second urging force (F2). A variation of the second fluid pressure (P2) is smaller than a variation of the first fluid pressure (P1). When the first urging force and the second urging force are balanced with each other in a horizontal direction, the gap (L1) between the vertical guide face (16a) and the vertical slide face (14a1) becomes a set value.
