Turbine maintenance
External leakage is often an early indicator of wear in seals or cylinder interfaces. If left unresolved, it can lead to pressure loss, unstable turbine behaviour and increased mechanical stress.
Understanding the Problem
What is external leakage?
External leakage occurs when hydraulic fluid escapes from the cylinder, typically around seals, fittings or connection points. While often considered a minor issue, it can affect system pressure and lead to inconsistent performance over time.
Typical symptoms
Visible oil residue
Oil traces around the cylinder or nearby components are often the first sign of leakage.
Pressure instability
Fluctuations in hydraulic pressure may occur as leakage develops.
Irregular system behaviour
Operators may experience minor faults, uneven pitch response or repeated small interventions.

Solution
New cylinders
A new cylinder ensures optimal sealing, stable pressure and reliable operation. Replacing worn components restores system performance and reduces the risk of recurring faults.
Solution
Up-tower repair kit
The up-tower repair kit enables efficient on-site intervention, reducing downtime and avoiding the need for full component replacement. All essential tools and parts are prepared for safe and controlled repairs.
