Micro Hydro-power Generator Trainer Using Pelton Wheel Turbine Model FM 16MH

Sci-tech Micro Hydro-power Generator Trainer using Pelton Wheel Turbine Model FM 16MH is an impulse transferred by the impact of water jet on the runner fitted with buckets. The change in the momentum of water jet results in the force on the buckets which turns the runner.  The torque developed is converted into DC supply using alternator. Pelton turbines are used in hydro-electric power plants operating with water source available at high heads and low volume flow rates. It is essential for students to understand the characteristics of Pelton turbines. The Sci-tech trainer is necessary equipment machinery for fluid mechanics educational institutions.   Pelton turbine and energy and its operations and performance Pelton Turbine for hydraulics laboratory is very important part of syllabus of fluid mechanics in educational institutions. A self-contained and robust training system that demonstrates the fundamental, principle, Operation and application of an off-grid educational micro hydro generation system. Trainer set specially designed, suitable system for learning and teaching purposes. The Sci-tech Pelton Wheel Turbine Demonstrator Model FM 16 has been designed to enable students to study the operation and characteristics of a typical Pelton turbine. The runner is mounted on a horizontal shaft and is fitted with buckets. A horizontal jet of water issuing from the nozzle produces a force on the bucket. The flow rate through the nozzle can be adjusted by varying the position of the needle valve inside the nozzle. The output of the turbine is measured using a brake band friction dynamometer. Digital RPM indicator with proximity sensor is provided to measure shaft speed. The runner and nozzle assembly is enclosed in a casing. The bottom of the casing is open and allows water leaving the buckets to drain. The front face of the casing is made transparent using Perspex to allow observation of turbine during operation. The unit is a compact and designed for quick and easy setting up of experiments. All components and instrumentation are placed in robust and mobile frame.  List of Experiment  v  Study of construction of Pelton turbine v  Determination constant head characteristics curve  v  Determination of constant speed characteristics curves.  v  Determination of constant efficiency curves. v  Iso-performance curves  vDemonstration of form of mini power generation for homes and communities that are close to water sources like rivers and streams   Technical Specifications Micro Hydro Trainer Structure ·       Constructed by steel profile structure with powder coated panel ·       Equipped with digital AC voltage and ampere display meter ·       AC Electrical power 220 -240V with MCB electrical input ·       Moveable trainer with lockable castor wheels   Pelton Turbine Micro Hydro Generator a)     Rating: 50W to 500W b)     Composite aircraft grade light aluminum material blades §  Number of buckets: 16 - 24 Drum Radius: 50mm – 200mm Bucket depth: 14mm – 25mm Jet diameter: 10mm – 15mm Shaft diameter: 10mm – 20mm Rated speed: @ 4000 rpm Torque: 40N – 100N     Brake:     Pulley diameter: 60 mm – 100mm.     Effective radius: 50 mm – 90mm.             Water pump, computer controlled:     Maximum pressure: @7 bar.     Maximum water flow: 80 l/min at 5.4 bar. §  Pressure sensor: 0 to 100 PSI (0 to 6.7 bar). §  Load cell - force sensor: 0 - 100N. §  Flow sensor: 2 to 150 l/min. §  Speed sensor: 0 - 4000 rpm. §  Water SS, capacity: 130 l approx. ·     Output alternator winding device: Overall 3 phase ·     Generator: 3 Phase ·     Permanent Magnet Rotor efficiency of 90% AC Variable Frequency Drive ·       Input 1P AC 220 -240V Variable frequency drive unit ·       Output 1P AC 220 -240V ·       Power: 0.5 ~ 1.5kW Water Pump ·                Power: 180W ·                Supply: 1 phase ·                Power: 0.5 ~ 1.5kW DC/AC Inverter ·       Continuous power: 500W ·       Surge power: 1000W ·       Rate Output Voltage: 220 V Continu
