Problems solved by technology

[0007] Disadvantages of said known hydraulic motor are its complex design and its high labor-intensive manufacture and installation, due to the use of large-sized and metal-intensive parts helical casing, stator, draft tube and impeller, and the need to use particularly bulky The rotating mechanism to change the position of the vane of the guide assembly
This design arrangement of the known hydraulic motors also requires a high labor expenditure for factory manufacture, transport and installation of the individual components
[0008] Said known hydraulic motors also have low specific power and limited performance and functionality

Embodiment Construction

[0023] The hydraulic motor comprises a turbine housing 1 shaped as a hollow double-pitch helical cylinder. One end 2 of the turbine housing 1 is fixedly attached, for example by welding, to a guide assembly 3 which in turn has a drive 4 for opening or closing the guide when water is supplied to the turbine housing 1. Component 3. The guide assembly 3 is made in the form of a sector gate 5 which is positioned in a closed chamber 6 and rotates in a pivot support 7 . The body 8 of the impeller 9 , having a diameter equal to the nominal diameter of the turbine casing 1 , is detachably mounted on a shaft 10 mounted on bearings 11 and kinematically linked to the outer motor (not show). The blades 12 of the impeller 9 are rigidly fitted to the body 8 of the impeller 9 and fitted into the cavity of the turbine housing 1 . The blades 12 can be fitted to the body 8 with the possibility of rotation relative to an axis positioned at an angle, for example at right angles, to the axis of...

Abstract

The invention relates to hydraulic power engineering, in particular to reactive hydraulic engines. The hydraulic engine comprises a guiding apparatus 3, a turbine chamber 1, a working wheel 9 which consists of a body with blades mounted thereon and is fixed to a shaft which is mounted in a bearing, and also a suction pipe 14. The turbine chamber 1 is in the form of a hollow cylinder, one end of which is connected to the guiding apparatus 3 while the other end thereof is connected to the suction pipe 14, and the blades of the working wheel are situated directly in the cylinder cavity. The guiding apparatus 3 is mounted upstream of the turbine chamber 1. The working wheel is detachably fixed to the shaft. The structure of the hydraulic engine is simplified and the operational and functional possibilities of said engine are increased.

Description

technical field [0001] The present invention relates to hydraulic power engineering, in particular to reaction hydraulic motors, intended for use in hydraulic power units of hydroelectric power stations, which use the working fluid - water - over a wide range of drops. Hydraulic motors can be used to generate mechanical energy and a pressure supply of working fluid. Background technique [0002] A hydraulic engine is known comprising a volute turbine casing, the vanes of a multi-blade guide assembly, an impeller and water supply and outlet components, wherein the volute turbine casing is connected to the circumferential band of the turbine stator, the multi-blade The guide assembly is mounted between the circumferential bands of the turbine stator, the impeller is mounted in the impeller chamber and is rigidly attached to the shaft (RF Patent No. 2306452, IPCF03B3 / 00, filed 28 October 2005, August 2007 published on the 20th). [0003] A disadvantage of said known hydraulic...
