(EN) VERTICAL IMPULSE DOUBLE-NOZZLE INTEGRAL TURBINE
(FR) TURBINE INTÉGRALE À DOUBLE BUSE À IMPULSION VERTICALE

Abstract
(EN)
A vertical impulse double-nozzle integral turbine, comprising a draft tube (1), a generator (2), a group of water inlet pipes (3) and a pressure pipe (4); the pressure pipe (4) consists of a first conduit (401) and a second conduit (402), a filter assembly (5) is provided between and in communication with the first conduit (401) and the second conduit (402), the filter assembly (5) comprises a positioning pipe (6), a filter pipe (7) and a telescopic tube (8); one end face of the positioning pipe (6) is fixedly connected to one end face of the first conduit (401) by means of a flange and bolts, the positioning pipe (6) is located inside the first conduit (401), and an external threaded sleeve (601) is fixed on a surface of the flange on the positioning pipe (6), the outer diameter of the filter pipe (7) is the same as the inner diameter of the positioning pipe (6), and a positioning ring (701) is fixed at one end of the filter pipe (7). The filter assembly is mounted between the first conduit and the second conduit of the pressure pipe, solving the problems of blocking of the water inlet pipes and easy damage to an impeller caused by impact of foreign matter.

L'invention concerne une turbine intégrée à double buse à impulsion verticale, comprenant un tube aspirateur (1), un générateur (2), un groupe de tuyaux d'admission d'eau (3) et un tuyau de pression (4); le tuyau de pression (4) comprend un premier conduit (401) et un second conduit (402), un ensemble filtre (5) est disposé entre le premier conduit (401) et le second conduit (402) et en communication avec ceux-ci, l'ensemble filtre (5) comprend un tuyau de positionnement (6), un tuyau de filtration (7) et un tube télescopique (8); une face d'extrémité du tuyau de positionnement (6) est reliée de manière fixe à une face d'extrémité du premier conduit (401) au moyen d'une bride et de boulons, le tuyau de positionnement (6) est situé à l'intérieur du premier conduit (401), et un manchon à filetage externe (601) est fixé sur une surface de la bride sur le tuyau de positionnement (6), le diamètre externe du tuyau de filtre (7) est le même que le diamètre interne du tuyau de positionnement (6), et un anneau de positionnement (701) est fixé à une extrémité du tuyau de filtre (7). L'ensemble filtre est monté entre le premier conduit et le second conduit du tuyau de pression, ce qui permet de résoudre les problèmes de blocage des tuyaux d'admission d'eau et d'endommagement facile d'une turbine provoquée par l'impact d'une matière étrangère.
