Dynabrade Wind Energy Solutions & Applications
As a worldwide leader in abrasive power tool innovation, Dynabrade proudly delivers a superior range of pneumatic tools designed for the fast-growing Wind Energy industry. Built to Dynabrade’s renowned standards, these tools optimize the manufacturing of molds, towers, blades, nacelles, and beyond.
Molds
A hegesztés szilárdságának biztosításához az egyik lépés a "tiszta", bevonatoktól, rozsdától és egyéb szennyeződésektől mentes felülettel való kezdés. A Dynabrade légszerszámok három fő módon készítik elő az élt a hegesztéshez: Csiszolás, csiszolás és hántolás. A "csiszoló" kifejezés számos különböző szerszámra utal, amelyek hasonló feladatokat látnak el. A Dynabrade különféle "csiszológépeket" gyárt, amelyek jellemzően ragasztott és bevonatos csiszolókorongokat fogadnak el, de használhatnak nem szőtt csiszolóanyagokat és huzalos termékeket is.
Towers
Low cost materials are especially important in towers, since towers can represent as much as 65 percent of the weight of the turbine. Prestressed concrete is a material that is starting to be used in greater amounts in European turbines, especially in off-shore or near-shore applications. Concrete in towers has the potential to lower cost, but may involve nearly as much steel in the reinforcing bars as a conventional steel tower.
Turbine Blades
Most turbine blades or rotor blades in use today are built from glassfiber-reinforced-plastic. Other materials that have been tried include steel, various composites and carbonfilament-reinforced-plastic. As the rotor size increases on larger machines, the trend will be toward high strength, fatigue resistant materials. As the turbine designs continually evolve, composites involving steel, glassfiber-reinforced-plastic, carbonfilament-reinforced-plastic and possibly other materials will likely come into use.
Nacelles
The nacelle contains an array of complex machinery including, yaw drives, blade pitch change mechanisms, drive brakes, shafts, bearings, oil pumps and coolers, controllers and more. These are areas where simplification and innovation can pay off.
