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 (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： In a wind turbine generator or other power generating apparatus of a renewable energy type, a hydraulic pump is driven by a rotor through a drive shaft. The hydraulic pump has electronically controlled low pressure valves and primary high pressure valves which are check valves that cannot open against a pressure differential. The hydraulic pump further includes auxiliary high pressure valves which can be used in alternative motoring mode, to slowly rotate the drive shaft and rotor in the opposite direction to during normal pumping in a cycle in which low pressure valves are selectively closed at around top dead centre and the high pressure valves are opened where required to drive rotation. Thus a motoring facility can be provided, for example to enable the blade of a wind turbine generator to be positioned as required for maintenance, without compromising the efficiency or long term reliability of the pump.
