1500kw Hydro Pelton Turbine for water head 90m 50HZ 60 hz on gird off gird

1. Nozzle and Flow Regulating Arrangement (Spear)
Nozzle is used to increase the kinetic energy of the water that is going to strike the buckets or vanes attached to the runner.
The quantity of water that strikes the buckets is controlled by spear. The spear is installed inside the nozzle and regulates the flow of water that is going to strike on the vanes of the runner. A nozzle containing spear is shown in the figure given below.
The spear is a conical needle present in the nozzle. It is operated by a hand wheel or automatically in an axial direction.
When the spear is move backward the rate of flow of water increases and when it is pushed forward the rate of flow of water decreases.

2. Runner and Buckets
Runner is a rotating part of the turbine. It is a circular disc on the periphery of which a number of buckets evenly spaced are fixed.
The buckets are made by two hemispherical bowl joined together. Each buckets have a wall in between two hemispherical bowl called splitter.
The splitter splits the jet of water striking the buckets into two equal parts and the jet of water comes out at the outer edge of the bucket.
The buckets are designed in such a way that the jet of water strike the buckets, deflected through 160 degree to 170 degree.
The buckets of the Pelton turbine are made up of cast iron, cast steel bronze or stainless steel.

3. Casing
It prevents the splashing of the water and helps to discharge the water to the trail race. It also acts as a safeguard in the case of any accident occurs.
Cast iron or fabricated steel plates are used to make the casing of the 1000kw pelton hydro turbine generator.

4. Breaking jet
When the jet of water is completely closed by pushing the spear in forward direction than the amount of water striking the runner becomes zero. But still the runner keeps moving due to the inertia of the runner.
In order to stop the runner in the shortest possible time a small nozzle is provided which directs the jet of water at the back of the vanes. This jet of water used to stop the runner of the turbine is called breaking jet.
