Description

And it can be applied to a hydraulically operated windscreen and can be used to dampen hydraulic gears in the pressure lines of the hydroelectric station. Ie eten equalizing rvuervoir of hydroelectric power station, the second vertical numerus, and the radeelshnui with a horizontal perforated diaphragm ClJ. Iveeten is also a Hurriculum Repertoir HES; including vertical eMi eeTfej split gerizongal | a diaphragm located between the minimum and maximum nuclear currents and dynamic water levels in the tank and the vodonods that are connected to and below the diaphragm 23 However, the JEI diaphragm of these structures has a boiling point, which can lead to breakdown of the structure - improving the reliability of the structure by reducing the irregularity of the breakdown of the diaphragm. The goal is achieved by the fact that at the leveling reservoir of a hydroelectric station, including a vertical tank, separated by a horizontal diaphragm, located in Mazad with minimum and maximum marks of dynamic yponnefi water in CMJCOCTH, and the water lines connecting the cavities above and below the diaphragm, the diaphragm is made solid and the END of the conduits above the diaphragm are directed in pairs towards each other. The conduits are evenly spaced around the perimeter of the tank, and the ends of the diametrically opposite conduits above the diaphragm are directed towards each other. The reservoir is provided with a wall of water, and the water lines are divided into two groups in which they are parallel to each other, with the groups of water lines located opposite each other. The water wall is mounted on the diaphragm between the nish: and may have a T-shaped cross section. 1 shows a leveling reservoir of a hydroelectric station, top view; in Fig. 2, section A-A in Fig. 1 in Fig. 3 is an equalization tank with the execution of arguments in the form of niches in the lining of the mine, top view; figure 4 - section bb and fig.Z} on fig.Z - surge tank with a wall of water, the kind of erekha; figure 6 - section bb in FIG | 3) | in FIG. 7, the same wall with a wall having a cross-section. The haulage reservoir contains a rytikal & nougat {distance and capacity 1, a cell, for example, in the form of a mine in ecal maya, vmkoet 1 is divided by a level and a diaphragm 2, located between the levels of the cross section and the head of the system, and the structure of the system; (The armament is equipped with water reservoirs 5, e-dividing tanks of capacitance 1 above central unit diaphragm 2, diaphragm 2 is full of impermeability, and aerial control 5 above diaphragm 2 is directed in a twist direction to each other. The conduits 5 can 6t, JTi. They are evenly distributed around the tank perimeter one, 9, the ends 6 of the diametrically arranged water lines 5 above the diaphragm 2 are directed towards each other (Fig. 1-4). The water lines 5 can be made in the form of niches I) in the mine lining (Fig. 3-4). The reservoir can be equipped with a water wall 7, and the water lines 5 are divided into two groups in which they are parallel to each other, the npHieM groups of water lines 5 are located opposite each other, and the water wall 7 is installed on the diaphragm 2 between the lines (Fig, 5-7) . Steika 7 can have a T-shaped cross-section (Fig, 7), the work of a surge tank. It is based on the principle of quenching the excess kinetic energy of a stream by splitting it into separate jets, changing the direction of movement of these jets and splitting them. The flow of water during the discharge of the load from the hydroelectric station to the tank 1 when the diaphragm 2 is reached, by the conduits 5 is divided into separate jets, which. Poured into the top of the tank. above the diaphragm 2 in the horizontal direction, hit each other or into the water wall 7 and break. Thereby, the termed kinetic energy, in a quiet state, the flow continues upward movement. Such an implementation of the surge tank makes it possible to increase its reliability by reducing the likelihood of diaphragm breakage.
