Abstract

The invention relates to hydro-turbine construction and allows to increase the reliability of the hydraulic machines. Coaxial rods (CS) 5 and 6 are installed between the oil receiver 1 and the servo motor (CM) 2 inside the shaft 3 of the hydraulic machine and are connected to a plug 11 placed in the annular gap 4. The channels 15 of the caps communicate a cavity 7 between CSH 5 and 6 with the over-piston cavity 9 CM 2. The piston rod 12 of the piston 13 CM 2 is partially placed in the cavity 8 of the inner rod 6 and connected to the feedback link 14. When the oil enters KS 5 and 6 in the cavity 9 and 10 CM 2, the piston 13 moves. 6 make only a rotational movement relative to the sealing sleeves oil riem- nickname that reduces wear. 1 il.

Description

The invention relates to hydrotourism and hydroturbation and can be used in the oil distribution devices of rotary-vane hydraulic machines.

The purpose of the invention is to increase the reliability of the hydraulic machine.

The drawing shows the oil distribution device, a longitudinal section.

The oil-distributing device of the rotary-blade hydraulic machine contains an oil receiver 1, a servomotor 2 impellers installed between them inside the shaft 3 of the hydraulic machine with an annular gap 4 relative to the latter two coaxial rods 5 and 6, the internal cavities 7 and 8 of which are communicated with the over- and sub-piston cavity 9 and 10 of the servomotor 2, the plug 11, placed in the annular gap 4, and the feedback link 14 are kinematically connected with the rod 12 of the piston 13 of the servo 2 motor. Cap 11

provided with channels 15, which communicate a gap 25, and kinematically associated with

The bridge is 7 between the rods 5 and 6 with the supra-piston cavity 9 of the servomotor 2, and the rod 12 is partially spaced in the cavity 8 of the inner rod 6 and connected to the feedback link 14.

During the operation of the hydraulic machine, the oil from the oil receiver 1 flows through the rods 5 and 6 into the piston or sub-piston cavities 9 or 10 of the servomotor 2, as a result of which

moving the piston 13, kinematically associated with rotary vanes (not shown) and feedback link 14. In this case, the rods 5 and 6 perform only a rotational motion relative to the sealing sleeves (not indicated) of the oil receiver 1, which reduces their wear, thereby increasing the reliability of the hydraulic machine and increasing the turnaround time.
