A wind force 7 prevails, it is drizzling and is rather unpleasant. Up high, the rotor blades are swinging, but they are not yet moving – the wind turbine stands still. Why? It is 4 in the morning, and the extra portion of electricity is not needed. The structure will start briefly, and only then will the brakes be released. Nevertheless, it is already time to warm things up with the aid of SCHERZINGER pump power so that the enormous wind power can also effectively be utilized for electricity generation and the technology will not fail.

High-tech wind turbines are an integral part of renewable energy production – they continue to become bigger and more efficient. The gear architects manage to evenly distribute the gigantic loads in the gear unit with a higher number of planet gear wheels that circulate around the central sun gear wheel. The lubrication naturally has a significant role in such highly stressed gears. For this reason, the wind turbine wheels do not simply operate when the wind starts to blow. Before its brakes can be released for electricity generation, it must be warmed up: in this process, the gear lubrication pump, together with the heating of the gear oil, warms up to a minimal temperature. Once this is achieved, it presses the oil through the bearing points in the gear and transports it to the engagement points.

… and still a lifespan of 120,000 hours

Now the brakes are opened, and the wind turbine begins to rotate: The load on the bearing and engagement points of the gearing is enormous – the lubrication film must by no means tear off, otherwise the gear will bear permanent damage as a result. The pump systems perfectly designed for this case by SCHERZINGER ensure this. They enable the operation and ensure the impressive lifespan of 120,000 hours – this is equivalent to 24 times that of a car engine.
