About Pelton Wheel Turbine Apparatus
Pelton Turbine
Description of Pelton turbine:
Pelton wheel turbine is only impulse water turbine now in common use named in honour of Sir L.A Pelton (1829-1908) of Califonia, USA. It is a tangential flow impulse turbine. The water strikes the buckets along the tangent of the runner. The energy available at the inlet of the turbine is only kinetic energy. The pressure at the outlet of the Turbine is atmospheric this turbine is used for high heads.
The present set-up consists of a runner. The buckets are mounted on the runner. The water is fed to the turbine, though SS nozzle with a SS spear, by means of Centrifugal Pump, tangentially to the runner. Flow of water into turbine is regulated by adjusting the spear position by the help of a given hand wheel. The runner is directly mounted on one end of a central SS shaft & other end is connected to a break arrangement. The circular window of the turbine casing is provided with a transparent acrylic sheet for observation of flow on to the buckets. This runner assembly is supported by rigid MS structure. Load is applied to the turbine with the help of this brake dynamometer so that the efficiency of the turbine can be calculated. Pressure gauge is fitted at the inlet of the turbine to measure the total supply head to the turbine.

FAQs of Pelton Wheel Turbine Apparatus:
Q: How is the efficiency of the Pelton Wheel Turbine Apparatus measured?
A: The system allows direct measurement of input and output parameters such as power, discharge, head, and speed using built-in digital/analog meters and a dynamometer. Efficiency is calculated by comparing the mechanical power delivered by the turbine (measured with the brake/dynamometer) to the hydraulic power input from the pump.
Q: What type of research or experiments can be conducted with this apparatus?
A: This apparatus is ideal for laboratory experiments related to fluid machinery, such as efficiency analysis, energy loss studies, and performance evaluation of impulse turbines under varying flow, head, and load conditions. It is commonly used in engineering curricula for hands-on learning and advanced research projects.
Q: When should the water tank be refilled or maintained?
A: Thanks to its closed water circulation design, the water tank typically requires minimal refilling. Regular visual inspection for water level and cleanliness, especially before starting a new set of experiments, is recommended to ensure accurate results and maintain equipment longevity.
Q: Where can the Pelton Wheel Turbine Apparatus be installed?
A: This compact apparatus, with dimensions 1200 mm x 800 mm x 900 mm and a weight of approximately 65-80 kg, is best suited for hydraulic laboratories, teaching institutions, technical training centers, and research labs. Its durable build and moderate footprint allow ease of installation on standard laboratory benches or platforms.
Q: What is the process for operating and recording measurements on the turbine?
A: Operation involves filling the tank with water, starting the electric centrifugal pump, adjusting the nozzle for the desired flow, and using the rope brake/dynamometer to apply load. Digital and analog meters display real-time data on speed, discharge, and power. Data can be recorded manually or visually observed for experiment analysis.
Q: How does the closed water circulation system benefit the operator?
A: Closed water circulation greatly reduces water consumption and limits operational mess, facilitating repeated experiments without frequent refilling. This environmentally friendly feature ensures practical laboratory usage, minimizes downtime, and supports sustainability in teaching environments.
Q: What materials and features enhance the durability and safety of the equipment?
A: With an MS structure featuring powder coating, stainless steel tank and fittings, and aluminium/brass impeller, the apparatus resists corrosion and wear. The transparent protective cover offers safety during operation, while adjustable settings and reliable displays ensure secure and accurate experimentation.
