Sealing fasteners to optimise and protect wind turbines

Primus Wind Power is positioning itself to meet heightened demand for its wind turbines. The manufacturer received funding from the National Renewable Energy Laboratory to optimise wind turbine system designs and contribute to the wind turbine deployment efforts in the USA. Part of the process includes prototyping and testing hardware and components that are resilient and can perform in harsh weather. One of the largest concerns is the ability to withstand water, saltwater, torrential rain, hurricanes and high winds, repeatedly and over long periods of time. To ensure that water would not enter through the external face cover of the wind turbine and potentially damage the screws or its inner components, Primus Wind Power asked engineering expert John R Marshall Jr, PE, owner of Ransford Engineering, to perform a series of water ingress tests. When compared to other fastening options, such as washer gaskets, Zago sealing screws engineered with a 360° O-ring under the head of the screw successfully prevented water seepage. Zago corrosion-resistant sealing fasteners are engineered with a custom groove underneath the head of the screw, and when combined with a rubber O-ring and tightened, form a 360° leak-proof seal. This seal will not break or crack once the screw is torqued, preventing seepage or leakage of liquids, gases and more from damaging equipment or the environment. When paired with a rubber O-ring such as EPDM, the sealing screw can withstand strong winds, torrential rain, saltwater, extreme heat, frigid temperatures, snow, moisture and dust, etc. With unlimited shelf life, an EPDM O-ring is suitable for sealing outdoor devices. “In addition to passing the water ingress test, investing in Zago sealing fasteners makes sense,” said Ken Kotalik, director of global sales and operations, Primus Wind Power.
