Abstract

The invention prevents the ingress of oil into the watercourse. In the cavity of the sleeve 1, having rotary and blades 2, there is a servomotor 3 of the mechanism 4 of rotation of the blades with pressure and drain piping 5.6 and heaters 7. In the pipelines 5.6 there are intermediate pistons I. Cavity sleeve 1 and pipelines 5.6 from it to the pistons 8 are filled with thermoplastic fluid. Oil leaks into the watercourse are prevented due to the absence of oil pressure in the impeller blade control system and the monolithic state of the thermoplastic fluid in the impeller sleeve. 1 il.

Description

I The invention relates to hydro-agroinstruc- tion and can be used on hydroelectric power x, using rotary-blade hydrodynamics, 1

The purpose of the invention is to prevent oil from entering the watercourse, I The drawing shows the working jiieco rotary-vane hydraulic turbine, a slit.

The rotary blade turbine impeller contains a sleeve 1 with rotating blades 2 and located in the cavity of sleeve 1 of the servo-3 mechanism 4 of rotation of the blades with pressure 5 and drain 6 pipe

rovodami The impeller additionally contains

The sleeves of the sleeve 1, the heaters 7, and {lines 5 and 6 are equipped with intermediate tailors 8 that are located 1, and the cavity of sleeve I and the pipelines 5 and 6 in the section from it to the pottery 8 are filled with a tremoplastic

(By IDENTITY,

When changing the operating direction to the optimum angle of installation of the blades of the 2 hydroturbines, 1 | 1 follows next method. I On the stopped unit, include heaters 7, after melting the thermoplastic fluid, from the pressure in the oil-pressure control system to the nominal value. The oil transfers the pressure of the thermoplastic fluid through the intermediate torsion bar 8, which, acting on the servomotor 3, causes

em it to the desired position. The displaced part of the thermoplastic fluid under the servomotor 3 moves the intermediate piston 8 in the direction of discharge, after setting the required angle of rotation of the blades. the impeller heaters 7 are turned off, the thermoplastic fluid hardens, as a result of which all the details of the mechanism 4 of rotation of the blades 2 of the turbine are monolithic, the pressure in the oil pressure system is released and the unit is put into operation.

Thus, the absence of oil pressure in the system for regulating the impeller blades and the monolithic state of the thermoplastic fluid in the hub of the impeller exclude oil leaks into the watercourse.
