SU399973A1 - DEVICE FOR COOLING THE HYDRO AGREGATE - Google Patents

Description

one

The invention relates to the field of hydropower and can be used in hydraulic units.

Devices are known for cooling hydraulic units, generators and bearings of turbines using a pumping system with a hydroelectric station head less than 12 m and more than 60 m.

The aim of the invention is to reduce energy costs.

This is achieved by the fact that the pressure pipes of the cooling system consumers are connected by an additional pipe to the cavity under the turbine cover, into which water flows through the labyrinth seals of the impeller.

The drawing shows the proposed device for cooling the hydraulic unit.

It contains the generator 1 and the impeller 2, the cavity under the cap 3 of the pipe is connected by an additional pipe 4 through the manifold 5 with coolers b and the drain pipe 7.

When opening its apparatus from the spiral chamber, water enters the blades of the impeller 2. The main part of the water after the working cycle goes into the lower reach, and some of the water passes through the labyrinth seals (not shown) into the cavity under the pipe cover, through the nozzle 4 collector 5,

and then goes to the coolers 6 and the drain pipe 7, cooling the hydraulic unit.

Subject invention

A device for cooling a hydraulic unit, including its generator and a hydro turbine with a lid, containing pressure pipelines connected to a power source, characterized in that, in order to reduce energy costs, the pressure pipelines are connected by an additional pipe with a cavity under the turbine cover.
