With a drain, the drain pipe with which it is connected is the inlet. a tapering nozzle is reported by the inlet. The case is made spiral. The hydraulic motor is additionally equipped with one or more drainage systems, nozzles and bodies with hydraulic turbines. The blades of hydraulic turbines are made bucket-shaped, the hubs are conical. The turbines are mounted on the same shaft. The hubs of the twin turbines are oriented vertices to each other. Nozzles are placed between twin turbines. The drainage systems are bent at an angle of 90 °. 1 s.p. f-ly, 1 ill.

Description

The invention relates to the field of hydropower,

The chain of the invention is to provide a channel hydraulic motor that does not have the drawbacks mentioned above.

A general view of such a hydraulic motor is shown in the drawing.

Two hydraulic turbines are located on the drive shaft 1, consisting of bucket-shaped blades (6), which are fixed to the conical hubs (7), and the hubs of 2 twin turbines face each other with their vertices. The turbines are installed in spiral housings (5), which are attached to supports (9). At the water inlet (marked by arrows) there is a narrowing water inlet (10), and at the outlet there are drainage pipes (2) and a drain pipe (3) connected to them by its inlet, Kromety, a narrowing nozzle (4) is connected to the inlet of the drain pipe. All intake water intakes are protected by protective nets at the water inlet (11).

The hydraulic motor operates as follows:

The stream of water accelerated in the tapering water inlet enters the spiral casing (5) and, passing around the turbine blades (6), transfers its kinetic energy in layers to the rotation of the turbines. Water from the turbine blades enters the conical surface of the hubs (7) and, with a 90-degree turn along the drainage system (2) and the drain pipe (3), leaves the bodies (5). In order to accelerate the discharge, a narrowing nozzle (4) is brought up to the inlet of the drain pipe.

The turbines transmit rotation to the drive shaft (1) directly without any drive parts.

The advantages of this hydraulic motor include the following:

The ability to install on one drive shaft, as one or several turbines (in pairs), having significant dimensions, both in diameter and in length due to the fact that the spiral turbine casing is almost. bearing bearings are completely unloaded, both from axial and radial loads.

Provided free exit of water from the housing due to the ejection action

the narrowing nozzle brought to the drain pipe.

Simplicity in manufacturing and reliability about long work.

This engine can be used on all high-speed riverbeds, as well as on the drainage paths of hydroelectric power plants, industrial enterprises and, even, in pressure lines of water supply. Of course, with such use, it is necessary to manufacture an accelerating nozzle. The pressure losses here are insignificant, they can be equated to the losses in the pipeline due to its rotation by 90 degrees twice.
