FRANCIS TURBINE [4 records]

Record 1 2017-05-31

English

Subject field(s)
  • Hydraulic Turbines
DEF

A machine in which the energy of a moving mass of water or other fluid is converted to mechanical work.

CONT

Hydraulic turbines find their major application in the exploitation of natural water heads, produced by damming of rivers, where they are coupled to generators to provide hydroelectric power.

OBS

The main types of water turbines are : the Pelton wheel for high heads, the Francis turbine for low to medium heads, and the Kaplan turbine for a wide range of heads.

French

Domaine(s)
  • Turbines hydrauliques
CONT

Turbine hydraulique. [...] Une turbine est à axe vertical ou horizontal, à passage axial ou radial. On distingue également les turbines à action, dans lesquelles les pressions à l'entrée et à la sortie de la roue mobile sont les mêmes (turbine Pelton), et les turbines à réaction, dans lesquelles la pression à l'entrée est plus grande que la pression à la sortie de la roue (turbine Francis).

Spanish

Campo(s) temático(s)
  • Turbinas hidraúlicas
CONT

Las turbinas hidráulicas se usan casi exclusivamente (acopladas con un alternador) para convertir en energía eléctrica la fuerza viva del agua que pasa, a través de ellas, de un nivel a otro inferior.

Record 2 2016-09-21

English

Subject field(s)
  • Hydraulic Turbines
CONT

The Francis turbine … is the most popular type of [mixed-flow turbine] in which water enters in radial direction and exits in axial direction.

French

Domaine(s)
  • Turbines hydrauliques
CONT

Turbine Francis. Cette turbine, du type à réaction, est utilisée pour les moyennes et basses chutes. Le distributeur est formé de deux flasques plans et parallèles entre lesquels se trouvent les aubes directrices mobiles permettant de modifier le débit de zéro jusqu'à une valeur maximale.

Spanish

Campo(s) temático(s)
  • Turbinas hidraúlicas
CONT

La turbina Francis funciona por reacción. Consta de un conducto circular que comunica con el distribuidor por toda la periferia del mismo; dicho distribuidor consiste en una corona de paletas directrices que sirven para orientar y proyectar los chorros de agua sobre los álabes del rotor, así como para regular el caudal y, consiguientemente, la velocidad de la turbina [...]
