Hydropower Equipment 20000KW Pelton Hydro Turbine with High Efficiency Pelton Wheel

Hydropower Equipment, Pelton Hydro Turbine / Pelton Water Turbine with Synchronous Generator, Speed Governor, Inlet Valve 

Descrition:

A Pelton wheel is an impulse-type water turbine invented by American inventor Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water.

Nozzles direct forceful, high-speed streams of water against a series of spoon-shaped buckets, also known as impulse blades, which are mounted around the outer rim of a drive wheel (also called a runner). As the water jet hits the blades, the direction of water velocity is changed to follow the contours of the blades. The impulse energy of the water jet exerts torque on the bucket-and-wheel system, spinning the wheel; the water jet does a "u-turn" and exits at the outer sides of the bucket, decelerated to a low velocity. In the process, the water jet's momentum is transferred to the wheel and hence to a turbine. Thus, "impulse" energy does work on the turbine. Maximum power and efficiency are achieved when the velocity of the water jet is twice the velocity of the rotating buckets. A very small percentage of the water jet's original kinetic energy will remain in the water, which causes the bucket to be emptied at the same rate it is filled, and thereby allows the high-pressure input flow to continue uninterrupted and without waste of energy.

The Pelton turbine is widely used in hydropower station with the heads from 80-1000m.

Pelton turbine is consisted of runner, turbine case, nozzles assembly, inlet pipe, deflector etc. The runner is assembled in the shaft of the generator, torque transmission by ping.

lt utilizes the dynamic power of high pressure water flow to rotate the runner and force the rotor work, The center line of the jet is in the same plane as the runner while rotating.

Pelton turbine has the advantages of compact construction, stable running and easy operation. Normally, Small pelton turbine always arranged with horizontal shaft and one or two nozzles,   Medium size and larger Pelton turbines are most often arranged with vertical shaft, and equip four or six nozzles to obtain more power.

Applications:

Pelton wheels are the preferred turbine for hydro-power where the available water source has relatively high water head at low flow rates.

1.     Water head:  80 m - 1000 m

2.      Power: 500kw - 20000KW 

3.     Frequency: 50/60hz 

4.     Generator Output voltage: 0.4KVV, 6.3KV, or 10.5KV AC three phase,

If you are interested in the Pelton turbine, you should send some key parameters (such as net head, flow discharge, unit number, frequency, voltage) in inquiry.

We can supply pelton turbine generator above 500KW, supply the runner with Forge and CNC machine, or runner with cast abrading machine for your require.
