PRODUCTS Voith StreamDiver® StreamDiver® is a novel compact and eco-friendly turbine from Voith, designed to step in where usual hydropower plants may not be feasible. All over the world there are run-ofriver power stations with low heads whose soaring energetic potential could so far not be utilized. In order to take advantage of this unexploited potential, in cooperation with its subsidiary Kössler, Voith has developed the StreamDiver. The pioneering technical model of the StreamDiver ™ ensures bare minimum maintenance and operating costs. As it can be directly installed into a weir system, its installation can even make conventional power station structures needless. Construction technology and non-essential equipment can thus be condensed to a complete minimum. The bearings are water-lubricated, allowing for absolutely oil and grease-free operation. The compact make-up and eco-friendly features make the Stream- Diver particularly helpful in locations where active weirs or dams are already in place. O & M Features: Operation • High hydraulic performance • High efficiency of the permanent magnet generator • Oil-free operation, no pollution of environment • Submerged turbine generator unit, no visual impact Comprehensive Condition Monitoring • Reduction requirements for manual inspection • Planned and scheduled activities • Reliable Design and Reduced Number of Components Longer service intervals • Reduced requirements for inspection & maintenance actions • Reduced complexity for service and minimized downtime • Low costs for spare parts Advantages: • Economical solution, in particular for low heads • Easy integration into active weir systems or transverse structures • Ecological advantages due to water-lubricated bearings, allowing oil and grease-free operation • Low construction requirements, apt for universal use • Least operating and maintenance cost • Standardized frame sizes Elecon EON series-gear units Elecon’s EON Series are technologically superior range of helical & helical bevel gears. C o n s i d e r i n g the industry requirements, the Elecon’s EON series offers superior flexibility and advantages and possesses wide range of features: Higher torque ratings. Foot print same as ET Series. Suitable for numerous applications. Various sealing options available. Different cooling options. Features Technical: • The power tables apply to normal conditions, i.e., drive by an electric motor, smooth operation, operation for eight hours per day, 2.5-fold starting torque relative to catalogue performance PN, 100% duration of operation, ambient t e m p e r a t u re 2 0 D e g C . Power for intermediate speeds can be interpolated linearly. • Higher drive speeds than indicated and selection as finite-fatigue strength gears on request. Reinforced bearings are optional for heavy external forces (e.g. output drive by pinion). Design: • Increased torque capacity • Different shaft designs as standard options • Modular concept casings enabling faster deliveries • Different sealing options • Better cost to performance ratio Efficiencies: • 99 % for single stage helical gear units • 98 % for double stage helical gear units • 97.5% for triple stage helical gear units • 97% for quadruple stage helical gear units • 97.5% for double stage bevel helical gear units • 97% for triple stage bevel helical gear units • 96.5% for quadruple stage bevel helical gear units Mounting: • Horizontal & Torque Arm mounting positions. Noise Levels: • Allowable noise level is 85 dB. Lower noise levels with additional add-ons can be achieved. Vibration Levels: • Allowable vibration limits is generally as per ISO 10816. Thermal Capacities: • In-addition to higher torques the EON series comes with optimized thermal ratings which are due to larger available surface area. Installation: • Before the gear unit is set up the operating instructions should be followed. The plant user should provide protection covers on rotating parts. 80 energetica INDIA · JAN | FEB16
