Abstract: A method and system are provided for cooling a heat-exchanger in a wind turbine that has an electric generator with a cooling air flow directed therethrough. Effluent cooling air flow from the electric generator is directed into an air ejector pump and acts as motive air through the air ejector pump. Cold air is drawn into the air ejector pump by the vacuum generated by the motive air moving through the air ejector pump. The heat exchanger is disposed in-line with the cold air flow so that the cold air is drawn through the heat-exchanger, removes heat from the fluid circulated through the heat-exchanger, and becomes heated air that is combined with the motive air and discharged from the nacelle.

Abstract: An apparatus and method are provided for installing a seal into a part. A main body of the apparatus has two wings, and a raised shoulder that extends along the main body and two wings. A bracket is attached to the main body, and has an internally threaded hole for engagement with a threaded knob. An installation member is attached to the main body, and includes an insertion wheel attached to a wheel carrier. The wheel carrier is configured to be slidably attached to the main body. The main body is mounted on a first portion of the part and the seal is at least partially installed in a second portion of the part, such that upon relative rotation between the first portion of the part and the second portion of the part the installation member installs the seal.

Abstract: A locating plate for locating a first piece of rotary machinery relative to a second piece of rotary machinery is provided. The plate has a first periphery surface for mating with a first receiving surface of the first piece of rotary machinery and a second periphery surface for mating with a second receiving surface of the second piece of rotary machinery. The plate also has at least one attaching device for use in attaching the plate to the first piece of rotary machinery and at least one removal device for use in removing the plate from the first piece of rotary machinery. The plate is removably attachable to the second piece of rotary machinery, and the second periphery surface is sizable independently from the first periphery surface.
