    摘要： A method of charging a hydro-pneumatic energy storage system is described. The system has a first hydro-pneumatic accumulator with a first hollow vessel. Disposed within the first hollow vessel is a first compressible volume containing a first amount of gas. The system has a second hydro-pneumatic accumulator with a second hollow vessel. Disposed within the second hollow vessel is a second compressible volume containing a second amount of gas. The gas contained in the first volume is pre-pressurized to a first hydrostatic pre-charge pressure and the gas contained in the second volume is pre-pressurized to a second hydrostatic pre-charge pressure. The second pre-charge pressure is higher than the first pre-charge pressure. In addition, the gas in the first volume is pressurized by discharging a non-compressible hydraulic fluid into the first vessel while keeping a quantity of non-compressible hydraulic fluid contained in the second vessel constant to keep the pressure of the gas contained in the second volume at the second pre-charge pressure.

    摘要： Provided is an accumulator, which: is capable of reducing the pressure difference that is generated by differences in coefficients of thermal expansion when liquid trapped in the liquid chamber and a sealed gas undergo thermal expansion during zero-down, thereby limiting the occurrence of plastic deformation in the bellows; and has a structure in which the parts are small and few in number. To achieve said purpose, the accumulator has a sealing member held on the port hole-side of the bellows cap via a seal holder. When operation of the machine is stopped and the pressure inside the pressure piping decreases, the sealing member contacts the sealing section and closes the liquid chamber. If liquid trapped in the liquid chamber when the liquid chamber is closed undergoes thermal expansion, the bellows cap moves in the direction away from the sealing section while the sealing member is still in contact with the sealing section. Since the sealing member is a rigid plate, the outer circumferential surface of which is covered by a flexible section obtained from a rubber-like elastic body, the flexible section allows relative movement of the bellows cap by undergoing shear deformation as a result of engagement with the seal holder.

    摘要翻译： 本发明提供一种蓄液器，该蓄液器能够减小由液体室内积存的液体和密封气体在零下降时发生热膨胀时的热膨胀系数的差异所产生的压力差，从而限制塑性变形的发生 在风箱里; 并且具有部件小而数量少的结构。 为了实现所述目的，蓄压器具有通过密封保持器保持在波纹管盖的端口孔侧的密封构件。 当机器的操作停止并且压力管道内的压力减小时，密封构件接触密封部并关闭液体室。 如果在关闭液体腔室时液体腔中的液体受到热膨胀，则在密封部件仍与密封部分接触的同时，波纹管帽沿远离密封部分的方向移动。 由于密封构件是刚性板，其外周表面被由橡胶状弹性体获得的柔性部分覆盖，所以柔性部分通过由于接合而经历剪切变形而允许波纹管帽相对移动 密封座。

    摘要： The invention relates to a turbine valve actuator (100) for controlling at least one valve unit of a media-operated consumer unit, such as a steam or gas turbine, having an actuating part drive (102) which has a movable actuating part (104), at least one first media space (106) and at least one second media space (108), wherein a pressure build up in the first media space (106) attempts to cause a movement of the actuating part (104) in a first direction (R) and a pressure build-up in the second media space (108) attempts to cause a movement of the actuating part (104) in an opposing second direction (GR), wherein the first media space (106) can be supplied with a fluid in predeterminable amounts by means of a supply arrangement (110) and the second media space (108) is acted upon by an energy accumulator (112). The invention is characterised in that the energy accumulator is at least one hydraulic accumulator (112) which is provided with a preload pressure and is permanently connected to the second media space (108).

    摘要： The purpose of the present invention is to prevent a seal provided inside a housing from becoming inserted between a bellows cap and a seal holding member provided to an inner peripheral side of the seal, thereby inhibiting damage to the seal and bellows. Accordingly, provided is an accumulator in which: a bellows and a bellows cap are used to partition the interior of an accumulator housing provided with an oil port connected to pressure piping of an apparatus, into a gas chamber having gas enclosed therein and a fluid chamber leading to the oil port; the fluid chamber is sealed by being brought into contact with the seal by a stroke of the bellows cap when the pressure in the pressure piping is reduced; and the seal is held by a seal holding member provided to an inner peripheral side thereof. The accumulator is characterized in that the seal diameter of the seal, said seal being located in such a position as to be in contact with the bellows cap, is equal to or greater than the effective diameter of the bellows.

    摘要： A hydraulic accumulator (10) has a rotatable gas manifold (12). The accumulator (10) includes a shell (16) having a hydraulic fluid pressure end (26) and a charged gas end (28). The charged gas end is closed by a closure assembly (44). The manifold (12) includes a body (102) and a locking connector (150). The body (102) includes fluid ports (112, 114, 116) that are in fluid communication with an annular connector port (182). The locking connector (150) includes a threaded stem (152) that is connected to the closure assembly (44) and provides a single point rotatable connection for attaching, detaching and aligning the fluid ports (112, 114, 116) relative to the accumulator (10).
