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 large hydraulic radial piston pump (1) suitable to be driven by the turbine (4)of a wind turbine generator has a circular cover (40) formed from at least three cover segments (42). Underneath the cover segments a seal (46) 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 (60) outside the seal, or within the seal, facilitates pulsatile flow into the cylinders of the pump during operation.

摘要： A method of performing maintenance on a hydraulic pump 8 attached to a rotor of the power generating apparatus of renewable energy type and being formed such that a pump housing 21 houses a pressurized-oil production mechanism 50 for producing pressurized oil with use of rotation of the rotor, the pump housing 21 including a cylindrical shell 22, and a first end plate 30 and a second end plate 38 arranged at both ends of the cylindrical shell 22, the method comprising a slide step and a maintenance step. In the slide step, the cylindrical shell 22 is slid along an axial direction of the hydraulic pump 8 so that the cylindrical shell 22 is separated from the first end plate 30 and passes an outer circumference of the second end plate 38 to expose the pressurized-oil production mechanism 50 having been covered by the cylindrical shell. In the maintenance step after the slide step, maintenance is performed on the pressurized-oil production mechanism 50 in such a state that the pressurized-oil production mechanism 50 is exposed.

摘要： A power generating apparatus of a renewable energy type has a hydraulic radial piston pump driven by a turbine. The pump has one or more cylinder blocks including axially spaced banks of cylinders. The cylinder blocks have low pressure fluid passages which extend radially outwards from the cylinders. High pressure fluid passages comprise a portion which extend axially out from the cylinders, located between pairs of circumferentially adjacent cylinders. High pressure valves are provided intermediate the cylinders and radially outwards of the cylinders. The cylinder blocks have a neutral plane. The benefit of the configuration is that the cylinder blocks are strongly resistant to bending and torsion.
