Pelton turbine

These turbines are generally used for sites with heads greater than 3meters. Nozzle arrangement at the end of penstock helps the water to accelerate. The jet will hit the splitter of the buckets which will distribute the jet into two.

Water leaving those wheels typically still had high spee carrying away much of the dynamic energy brought to the wheels. Later this mechanical energy can be converted into electrical energy with the help of an electrical alternator. The pressure at the inlet and outlet of the turbine is atmospheric pressure.

This type of turbine is used for high head. Therefore the power transmitted to the turbine wheel is of the incoming water jet power. This is because the water jet is reversed by the wheel cup design 1degrees back towards its source. The high speed water jets emerging form the nozzles strike. The absolute velocity from the nozzle will be: 0. C1u can be set to when dimensioning the turbine.

It operates with a very flat efficiency curve Each bucket splits the water jet in half, thus balancing the side-load forces or thrust on the wheel and thus the bearings. Individualised design at state-of-the-art technology provides highest efficiency, longest lifespan and secures extraordinary profitability.

Water hammer is completely eliminated due to the chamber’s open air operation and a deflection plate adjusts flow to maintain efficiency over fluctuating site conditions. Not directly relevant in a turbine section. Our main products included: (1) Axial flow type turbine generators series (2) Turgo turbine generators series, e. Tubular turbine generators series, e. Pelton Turbine Hydroelectric Setup. A gauge measures inlet pressure. Get the best deals on pelton turbine when you shop the largest online selection at eBay.

Students adjust the spear valve and measure inlet pressure,. The system is instrumented to allow documentation of the efficiency of the energy conversion in the hydropower plant. PELTON WHEEL TURBINE THEORY The power output of the turbine is: P = T ω where T is the torque on the rotor and ω is the rotational speed of the rotor. For the lab turbine, β is 168o and K is 0. Size of Bucket: Axial Width , radial length , depth.

The water is directed with high speed through nozzles against the buckets, arranged around the circumferential rim of a drive wheel – the runner. Setting the standard for hydropower efficiency. GE provides a full range of hydro turbines with the market-leading technology.
