400kw Turgo Water Turbine Generator For Micro Hydro Generator

 

overview

 

Turgo impulse turbines are well suited to power generation in South East Asia. Their robust design features and simple construction provide good reliability and availability. Machine efficiencies are maintained over a wide flow range and progressive efficiency reductions due to erosion by silt present in the water are minimal.

In common with other impulse turbines the Turgo has a flat efficiency profile over a typical site operational envelope. This contrasts with reaction machines where the comparable efficiency profiles are quite peaky and thus effective utilisation of available water is compromised,

particularly in installations where the flow varies over a wide range during a year. The Turgo impulse turbine’s flat efficiency profile can be further enhanced by the use of twin jet machines, and thus utilise more effectively the available water during seasonal flow variations.

Impulse machines are both simple and robust pieces of mechanical plant, and unlike their reaction cousins do not rely upon maintenance of close operational clearances for their continued efficient operation. In addition to reducing efficiencies, primarily due to increased internal leakage flows, Francis machines can be subjected to an increased axial thrust loading which in extreme cases could cause premature bearing failure.

Turgo impulse turbines are less affected by the erosive characteristic of silt laden water than Peltons where wear on the splitter edge leads to quite rapid reductions in efficiency. The runner geometry of a Turgo impulse turbine is such that even where blade leading edge erosion occurs the blade angles are essentially preserved and thus the efficiency reduction due to adverse flow incidence angles is negligible. We have experience with machines running under particularly arduous conditions that have suffered severe erosion damage without the Owner being aware of a reduction in performance.
