Abstract

The present invention relates to a lubrication system for a wind turbine ( 105 ). The lubrication system comprises at least one or more pumps ( 310 ), a tubing system ( 206, 207, 209 ), one or more lubricant reservoirs, and a filtering system ( 200 ). The filtering system ( 200 ) comprises at least one cylindrical filter container ( 100 ). Each cylindrical filter container ( 100, 100 a ) comprises at least one filter element ( 301 - 304 ). Each cylindrical filter container ( 100, 100 a ) defines a central axis ( 101 ) along its axial direction and the central axis ( 101 ) of each cylindrical filter container (100, 100a) is oriented in a direction forming an angle of at least 10° with respect to a vertical direction ( 102 ).

First claim

1 . A lubrication system for a wind turbine, the lubrication system comprising at least one or more pumps, a tubing system, one or more lubricant reservoirs, and a filtering system, the filtering system comprising at least one cylindrical filter container, each cylindrical filter container comprising at least one filter element, each cylindrical filter container defining a central axis along its axial direction, wherein the central axis of each cylindrical filter container is oriented in a direction forming an angle of at least 10° with respect to a vertical direction.

2 . The lubrication system according to claim 1 , wherein the cylindrical filter container of the filtering system is mounted to the lubrication system by means of at least one releasable clamp.

3 . The lubrication system according to claim 1 , wherein the filtering system forms a first and a second end, the first end being in fluid communication with the lubricant reservoir, the second end being in fluid communication with a lubrication point on the wind turbine, and wherein the lubricant enters at the first end of the filtering system and exits at the second end of the filtering system.

4 . The lubrication system according to claim 1 , wherein at least two filter elements of the filtering system are arranged fluidly in parallel to each other.

5 . The lubrication system according to claim 1 , wherein at least one of the cylindrical filter container(s) comprises at least two filter elements, the filter elements being arranged adjacent to each other along the central axis of the cylindrical filter container.

6 . The lubrication system according to claim 1 , wherein the filtering system is mounted directly on a drive train component of the wind turbine.

7 . The lubrication system according to claim 1 , wherein the filtering system is configured to deliver lubricant directly to the drive train component of the wind turbine through a single tube connecting the filtering system and the component.

8 . The lubrication system according to claim 1 , wherein at least one filter element forms part of a pipeline of the lubrication system.

9 . The lubrication system according to claim 1 , wherein the filter elements comprised in the filtering system have a diameter between 150 mm and 250 mm, and wherein the filter elements comprised in the filtering system have a length between 200 mm and 600 mm.

10 . The lubrication system according to claim 1 , wherein the filtering system is configured for inside-out filtration.

11 . The lubrication system according to claim 1 , wherein the filtering system is configured for outside-in filtration.

12 . The lubrication system according to claim 1 , wherein the central axis of each cylindrical filter container is oriented in a direction forming an angle in the range between 70° and 110° with respect to the vertical direction.

13 . The lubrication system according to claim 1 , wherein the lubrication system further comprises a heat-exchanging element arranged in or immediately adjacent to the filtering system.

14 . The lubrication system according to claim 1 , wherein the filtering system is mounted on the drive train component of the wind turbine, the filtering system being accommodated within a transport unit.

15 . A wind turbine comprising a lubrication system according to claim 1 .
