Title:
RENEWABLE ENERGY TURBINE GENERATOR PROVIDED WITH HYDRAULIC PUMP WITH A SEGMENTED COVER AND METHOD TO ASSEMBLY THE PUMP
Document Type and Number:
WIPO Patent Application WO/2013/030873
Kind Code:
A1
Abstract:
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.
