Embodiment Construction

[0016] A detailed reference will now be made to different embodiments, one or more examples of which are shown in each figure. Each example is provided by way of explanation and is not intended as a limitation. For example, features shown or described as part of one embodiment can be used in other embodiments, or used in combination with other embodiments to produce still further embodiments. The present disclosure is intended to include such modifications and variations.

[0017] figure 1 A wind turbine 100 is shown. The wind turbine 100 includes a tower 110 on which a nacelle 120 is installed. The nacelle 120 can rotate around the vertical axis of the tower 110. A generator (not shown) for converting rotational power into electric power is placed in the nacelle 120. The generator is connected to a central body 130 that can rotate about a horizontal axis. Three rotor blades 140 are connected to the central body 130. The rotor blades 140 and the central body 130 together fo...

Abstract

The disclosure relates to a method for monitoring a component in a hydraulic circuit, a monitoring device and a fluid turbine. The disclosure concerns a method for monitoring at least one component to be monitored in a hydraulic circuit (200) filled with a working fluid, the hydraulic circuit comprises at least one pump (210, 410, 420, 600, 700) for circulating the working fluid, wherein the method comprises:-changing an operational state of at least one first component (210, 215, 220, 230, 250, 260, 290, 300, 410, 420, 220, 510, 520, 600, 700) in the hydraulic circuit such that a working point of the at least one component to be monitored changes to a predetermined working point;-performing at least one measurement for monitoring the at least one component to be monitored. Further, the disclosure concerns a fluid turbine (100) comprising at least one fluid rotor (160, 415, 425), wherein the fluid rotor is adapted to convert kinetic power of a fluid into a rotation, the fluid turbine further comprises a hydraulic circuit (200) filled with a working fluid.

Description

Technical field [0001] The present disclosure relates to a method for monitoring at least one component in a hydraulic circuit. In addition, the present disclosure relates to a monitoring device provided for monitoring at least one component in a hydraulic circuit. According to another aspect, the present disclosure relates to a fluid turbine including at least one fluid rotor. Background technique [0002] The wind turbine may include a mechanical gearbox located between the wind rotor of the wind turbine and the generator. In a further embodiment, a hydraulic transmission may be used between the wind rotor and the generator. In a wind turbine with a hydraulic transmission between the rotation of the wind rotor and the rotor of the generator, there is a transmission ratio that can be arbitrarily selected. Usually, in traditional hydraulic equipment, the flow rate is controlled, but usually not quantified in the control system. For example, the volumetric performance or leaks...
