    In a hydroelectric facility, a vertically mounted rotatable shaft is connected to a motor-generator and carries a pump-turbine with a supplying pump disposed below and immersed in water, the supplying pump disengaging from the shaft when the pump-turbine is driving the motor-generator and engaging the shaft when the motor-generator is driving the pump-turbine and supplying pump, thereby providing a two-stage pumping mode and a single-stage generating mode.

    05 00 i The invention relates to hydraulic engineering and can be used in the development of pumped storage power plants. A reversible hydraulic unit is known, which contains a hydraulically coupled nasoo-turbine and an additional pump with suction and a first branch pipe, the impellers are mounted on the same shaft, and the water intake is ij. However, this hydrounit has insufficiently high efficiency with some modes of its operation. The aim of the invention is to improve the energy balance in a wide range of operating modes. To achieve this goal, the working shaft of the booster pump is mounted on the shaft using a one-way clutch and facing in the direction opposite to the impeller of the pump turbine, and the water intake is connected to the suction and discharge nozzles by means of two pipelines correspondingly, . The latch, and in the second louvered locking device. Moreover, the regulating valve of sleep & wife guiding ribs. In the drawing image) n hydraulic unit, longitudinal section. The reversible hydraulic unit contains hydraulically interconnected nasoo-turbine 1 and additional pump 2 with suction and HanqpHbiM nozzles 3 and 4, impellers 5 and 6 of which are installed on one shaft 7, and water intake 8, Impeller 6 of additional pump 2 is installed on the shaft 7 by means of the coupling 9 with a free wheeling and facing aside, prohibitively input impeller 5 of the pump-turbine 1, and water intake 8 CBfsaeA with suction and discharge nozzles 3 and 4 through two pipelines 1О and 11, respectively, in the first of which ra The control valve 12 is located and in the second the louvered locking device 13. The control valve 12 is equipped with guide ribs 14. The reversible hydraulic unit works as follows. In the pumping mode, the additional pump 2 and the pump-turbine 1 (working as a pump) rotate together, creating head The motion of the fluid proceeds as follows. From the water inlet 8, along the guiding ribs 14, the pipeline 1O, the nozzle 3, the water enters the additional pump 2, and then through the nozzle 4, the pipeline 11, the latch locking device 13 to the pump turbine 1 and to the consumer. In turbine mode, pipelines 11 and 1O are closed {the position of the valve 12 and the louver device 13 is shown in dotted lines in the drawing). The operating number & 6 of the additional pump 2 is switched off using the free-running clutch 9. I, the water from the consumer enters the pump-turbine 1, which in this case acts as a turbine, and then into the water intake 8. The invention optimally balances the energy in different operating modes of the hydraulic unit, and the transition time from one mode to another becomes shorter. In addition, the installation and disassembly of the hydraulic unit impellers is simplified, which reduces the time needed for maintenance work.
