Immersed hydraulic unit for controlling an underwater oil working station |
摘要 |
A reservoir (1) filled with fluid communicates through a central opening 21 with the inside of a flexible bladder 22 isolating the contents of the reservoir from the sea environment and equilizing the pressure inside the reservoir with the external hydrostatic pressure. An internal dividing wall 2 divides the reservoir into two compartments, the central compartment 3 to which is connected a duct 12 for the expanded fluid and housing a pump 8 for discharge to the platform and for draining water and the annular peripheral compartment 4 housing the pumps 5, 6 for feeding the compressed fluid to the accumulators. The installation can be used as a self contained hydraulic unit or fluid storage reservoir when the pressurized fluid supply is provided from the surface.
