    摘要: A system for reducing pressure in a subsea operator. In one embodiment, a subsea system includes an operator and a deintensifier. The operator includes a housing and a piston. The piston is movably disposed within the operator housing and divides an inner volume of the operator housing into a closing chamber and a second chamber. The deintensifier is fluidically coupled to the operator. The deintensifier includes a housing and a piston. The piston includes a closing surface and an opening surface. The closing surface is fluidically coupled to the second chamber of the operator housing. The opening surface is fluidically coupled to ambient pressure. The area of the closing surface is greater than an area of the opening surface so as to increase the pressure differential between the closing chamber and the second chamber and assist in moving the operator piston to the closed position.

    摘要: Higher pressure exists at the bottom of deep water (including other fluids). This system utilizes machinery to compress a compressible fluid matter such as air with deep water high pressure so as to store the energy in the compressed air having a smaller compressed volume. The compressed air is subsequently injected into an expansion chamber in which it releases the stored energy and returns to its original volume. In constant temperature, a 10 m3 volume of water provides 10 times pressure to compress a single volume to 1/10 its volume. When the pressure is reduced 10 times, the compressed air would return to its original volume to release the stored energy which can be utilized to rotate a turbine and in turn a power generator to generate electric power.

    摘要: Systems and methods for efficiently operating a hydraulically actuated device/system are described herein. For example, systems and methods for efficiently operating a gas compression and expansion energy storage system are disclosed herein. Systems and methods are provided for controlling and operating the hydraulic actuators used within a hydraulically actuated device/system, such as, for example, a gas compression and/or expansion energy system, within a desired efficiency range of the hydraulic pump(s)/motor(s) used to supply or receive pressurized hydraulic fluid to or from the hydraulic actuators. In such a system, a variety of different operating regimes can be used depending on the desired output gas pressure and the desired stored pressure of the compressed gas. Hydraulic cylinders used to drive working pistons within the system can be selectively actuated to achieve varying force outputs to incrementally increase the gas pressure within the system for a given cycle.

    摘要: In a pressure booster having a cylinder mechanism, a floating mechanism is disposed between pistons and a piston rod, the floating mechanism being capable of absorbing offset (off centered) loads that are imposed on the pistons from the piston rod. The floating mechanism is constituted from swing bolts connected to both ends of the piston rod, support plates mounted onto end surfaces of the pistons and which swingably support the swing bolts therein, and fixing plates disposed between the ends of the piston rod and the support plates.
