摘要： A large hydraulic radial piston pump suitable to be driven by the turbine of a wind turbine generator has a circular cover formed from at least three cover segments. Underneath the cover segments a seal in the form of a vulcanised rubber band extends around the entire periphery of the pump. Thus, the cover can be readily removed within the difficult to access location of a wind turbine nacelle, but a reliable seal can still be formed. An air pocket outside the seal, or within the seal, facilitates pulsatile flow into the cylinders of the pump during operation.

摘要： A hydraulic pump comprises (1) an outward ring (24), including demountable blocks (30) comprising piston cylinders (32), and an inward ring (21), comprising a ring cam (23), coupled through a drive shaft (8) to the blades of a turbine (4). To enable maintenance, the outward ring is decoupled from a torque limiting device (16, 17) and rotated relative to the inward ring. Demountable blocks are then removed from the outward ring using a crane (61) including a line (62) extending from above the centre of mass of the demountable block and including a resilient portion (66) so that although the crane supplies the majority of the force required to remove the demountable block, an operator provides some force, enabling the process to be controlled. The method is suitable for maintaining large hydraulic pumps in wind turbine nacelles (2).

摘要： A power generating apparatus is provided with a hub rotated by the renewable energy received via a blade, a rotating shaft connected to the hub, a hydraulic pump mounted on the rotating shaft and driven by rotation of the rotating shaft, a hydraulic motor driven by pressurized oil from the hydraulic pump, a generator coupled to the hydraulic motor, a support providing reaction torque on the hydraulic pump from the rotating shaft while allowing a displacement of the hydraulic pump in a direction perpendicular to an axis of the rotating shaft, the hydraulic pump being supported by a nacelle through the support, and a pressurized-oil piping which is at least partially constituted of a flexible tube and which connects an outlet port of the hydraulic pump to an inlet port of the hydraulic motor to supply the pressurized oil from the hydraulic pump to the hydraulic motor.
