Pelton Hydro Turbines (Impulse Turbines)

The features of the Pelton Hydro Turbines (Impulse Turbines):

They operate in a head range of 100 meters to 1000 meters and are primarily used for electrical power production. The power output ranges from 200KW to 20000KW, Runner diameters are between 0.13 and 5.81 meters. The speed range of the turbine is from 250 to 1000 rpm.

* The runner works by being heavily pushed with jet flow that is switched through injection nozzle from high-pressure pipe. The feature is that is works by impulsing the runner to rotate with kinetic energy of water flow, and the jet center of nozzle and the runner are in the same plane.
* It is divided into vertical type and horizontal type two kinds. Horizontal type each has 1-2 runner, each runner has 1-2 nozzle, vertical type each has only one runner, each runner has 2-4 nozzles.
* Single- double-, four-, five- or six-jet design available Horizontal or vertical shaft arrangements Jet deflectors for outstanding dynamic performance 2 or 4 bearing gen-set arrangements.
* Developed for use in demanding application with debris-containing water, optimized jet and runner design for highest efficiencies, nozzle control either electrically or hydraulically.
* This kind of turbine shall be of compact structure, reliable works and convenient operation.
* Runner cast from high grade, extremely wear resistant, stainless steel, maintenance free shaft seal design.

ADDNEW's Pelton Hydro Turbines (Impulse Turbines) is used for high water head with small water flow and appropriate to the power station of big load variation.
