Abstract
(EN)
Provided is a fluid centrifugal cross-flow action structural body, comprising a flow guide structural body (210), a fluid inlet hole structure (300), and a driving supporting structure (400). The flow guide structural body (210) is of a straight barrel structure formed by arranging several flow guide strips (211) in a surrounding manner. The fluid inlet hole structure (300) is arranged at the fluid inlet end of the straight barrel structure to form a fluid inlet hole (217) of the whole structural body. The fluid outlet end of the straight barrel structure forms a fluid outlet hole (218). A centrifugal impeller (100) is assembled in a space surrounded by suspension ends of the inner sides of the flow guide strips (211). The driving supporting structure (400) is arranged on the structural basis of the suspension ends of the inner sides of the flow guide strips (211) behind the centrifugal impeller (100). According to the structural body, a fluid flows to a flow guide face of the flow guide structural body (210) via the radial direction of the centrifugal impeller (100), is subjected to flow guidance of the flow guide face, and flows out of the fluid outlet hole (218) in the axial direction, reducing fluid conveying loss, and increasing efficiency.

L'invention concerne un corps structural à action d'écoulement transversal centrifuge de fluide, comprenant un corps structural de guidage d'écoulement (210), une structure de trou d'entrée de fluide (300) et une structure de support d'entraînement (400). Le corps structural de guidage d'écoulement (210) présente une structure cylindrique droite formée au moyen de l'agencement de plusieurs bandes de guidage d'écoulement (211) tout autour. La structure de trou d'entrée de fluide (300) est agencée au niveau de l'extrémité d'entrée de fluide de la structure cylindrique droite, afin de former un trou d'entrée de fluide (217) du corps structural entier. L'extrémité de sortie de fluide de la structure cylindrique droite forme un trou de sortie de fluide (218). Une roue à aubes centrifuge (100) est assemblée dans un espace entouré par des extrémités de suspension des côtés internes des bandes de guidage d'écoulement (211). La structure de support d'entraînement (400) est agencée sur la base structurale des extrémités de suspension des côtés internes des bandes de guidage d'écoulement (211), derrière la roue à aubes centrifuge (100). Selon le corps structural, un fluide coule vers une face de guidage d'écoulement du corps structural de guidage d'écoulement (210) par l'intermédiaire de la direction radiale de la roue à aubes centrifuge (100), il est soumis à un guidage d'écoulement de la face de guidage d'écoulement, et coule hors du trou de sortie de fluide (218) dans la direction axiale, réduisant ainsi la perte de transport de fluide, et augmentant l'efficacité.

一种流体离心贯流作用结构体,包括:导流结构体(210)、流体入口结构(300)和驱动支撑结构(400)。导流结构体(210)是由若干导流(211)条围成的直筒结构。流体入口结构(300)设于直筒结构的流体入端,构成整个结构体的流体入口(217)。直筒结构的流体出端,构成流体出口(218)。导流条(211)内侧悬置端围构的空间装配离心叶轮(100)。驱动支承结构(400)以位于离心叶轮(100)之后的导流条(211)内侧的悬置端为结构基础设置。该结构体使流体经离心叶轮(100)径向流向导流结构体(210)的导流面,经导流面导流,使流体轴向从流体出口(218)流出,降低了流体输送损耗,提高效率。
