Wind turbines
Maintaining wind turbines along with their associated installations in proper condition is a significant challenge. The primary goal of wind turbine maintenance is to extend its operational uptime between planned shutdowns and minimize the risk of failures.
As a company with extensive experience in repairs, we can offer a range of services related to wind turbine maintenance.
-
Disassembly of the wind turbine gearbox is commonly employed to conduct a comprehensive diagnosis of its components and determine the cause of its stoppage or failure.
-
-
Non-destructive testing allows for the detection of all types of defects and cracks, which can be very dangerous for the equipment. A broken piece can cause cascading damage throughout the entire gearbox area.
The non-destructive testing (NDT) methods we use include:
- Visual inspection
- Magnetic particle testing
- Penetrant testing
- Ultrasonic testing
- Radiographic testing
- Endoscopic testing
-
Destructive testing is carried out on those gearbox components that have been disqualified due to poor technical condition. We perform these tests to determine the cause of failure. For example, metallographic examinations of broken tooth fragments are conducted as part of this process.
-
-
Measurements of wind turbine components include:
- Measurements of body geometry (flatness, perpendicularity, concentricity, etc.) using the Leica Tracker measurement system
- Measurements of bearing housing sockets – using micrometers
- Measurements of runout – using dial indicators
-
Assessment of the technical condition of the gearbox with the indication of the cause of failure. We provide the customer with a recommendation for further action related to the elements of the gearbox.
-
-
Re-engineering of damaged components and making new components based on the developed documentation.
-
-
The wind turbine also contains various standardized components, such as gaskets, rings, seals, screws, washers, nuts, etc. However, the main and most important standardized components are bearings. Through collaboration with leading bearing manufacturers, we are able to select and replace them with new ones accordingly.
-
-
Comprehensive assembly includes:
- Steam cleaning of all parts directly before assembly
- Degreasing the meshing of teeth
- Securing screws with adhesive to prevent loosening due to vibrational nature of operation
- Tightening screws to the appropriate torque
- Ensuring proper bearing clearances
- Bearing assembly while adhering to temperature regime guidelines
- Disassembly
- Non-destructive testing
- Destructive testing
- Measurements
- Technical condition assessment
- Re-engineering of defective components
- Replacement of standardized components
