    摘要: A renewable energy turbine generator (1), such as a wind turbine generator, comprises a hydraulic pump (20), a hydraulic motor (24) and an oil circuit (26, 28) connecting the hydraulic pump and the hydraulic motor. Oil in the low pressure side (28) of the oil circuit is cooled and supplied to the working chambers (95) of the hydraulic pump. A reduced temperature oil feed provides additionally cooled oil to the bearings of the hydraulic pump and the hydraulic motor. Thus, cooler and more viscous oil is supplied to the bearings (84) of the hydraulic pump and/or hydraulic motor and warmer and less viscous oil is supplied to the working chambers, increasing the efficiency and lifetime of the bearings and of the working portions of the hydraulic pump and motor.

    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 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: An annular valve (1) has an annular valve member (4) and inner and outer annular valve seats (12, 14). Inner and outer sealing ridges (8, 10) are formed either on the annular valve member or on the valve seats. The inner sealing ridges are more resistant to plastic deformation than the outer sealing ridges. They may be thicker, or made from a harder material. Thus, the annular valve better resists damage arising from greater plastic deformation of the inner sealing ridge than the outer sealing ridge due to greater forces (Fi, Fo) acting on the inner sealing ridge than the outer sealing ridge in use.
