Abstract

An adjustable-blade hydraulic machine includes a guide apparatus, a turbine chamber, a working wheel that consists of body with blades installed on it and detachably mounted on the shaft, a suction pipe. The turbine chamber is arranged as helical hollow cylinder one end of which is connected to the guide apparatus and the other end is connected to the suction pipe, the blades of working wheel are placed just in cavity of the helical cylinder, and the guide apparatus is installed upstream of turbine chamber.

Description

water flow lines in the flow part of the machine behind the rotors in the turbine chamber. This provides a combination of improving the hydrodynamic characteristics of reducing energy losses, increasing the uniformity of the water flow and reducing the number of its turns in relation to the water flow velocities along the flowing flow part, which allows to simplify the construction parts of the hydraulic machine, which allows to increase the performance and reduce the dimensions of the hydraulic machine, therefore, the power and throughput capacity of the hydraulic- to increase its throughput capacity, specific to the machine, to expand its operational capabilities, toughness, as well as to expand the operational capabilities- to simplify the design while ensuring high efficiency while ensuring high efficiency hydraulic-efficiency. new car The technical essence of rotary vane hydraulics

The set task is solved by the fact that the claimed machine is explained by the drawing machine, which includes the guide apparatus, by the lines. a turbine chamber, an impeller, which consists of a rotor body with blades installed on it and a blade hydraulic machine is schematically presented in Fig. 1; connector fixed on the shaft, which is installed in Fig. 2 - cross section AA in Fig. 1; bearing, as well as the suction pipe, according to Fig. 3 - the general view of the impeller, the useful model is new in that the turbine chamber view B in Fig. 1. made in the form of a helical hollow The rotor-blade hydraulic machine includes a cylinder, one end of which is connected to the direction of the turbine chamber 1, made in the form of a two-crank apparatus, and its other end is connected to a thin helical hollow cylinder. suction pipe, blades of the impeller One of the ends 2 of the turbine chamber 1 is fixed, placed directly in the cavity of the screw support, connected by welding to the guide of the cylinder, and the guide apparatus is placed by the apparatus 3, which in turn is provided in front of the turbine chamber. It is also new that the water device 4 for opening or closing the nominal internal diameter of the turbine chamber when supplying water to the turbine chamber 1. The guide is equal to the diameter of the impeller. apparatus C is made in the form of a needle attachment

Causal relationship between the totality of the formation. The body 5 of the working wheel 6 is detachable, the main characteristics and technical result of which is achieved on the shaft 7, which is placed in the bearing, is as follows. ku 8 and the kinematic is connected with the external

Execution of the turbine chamber in the form of a screw machine (not shown). Blades 9 of the impeller of a similar hollow cylinder, as well as 6 are rigidly installed on the body 5 and placed in the groove of the blades of the impeller directly in the cavity of the turbine chamber 1. Blades 9 can be installed on the body 5 of the impeller 6 with uniform intersection of the water flow from the guide with the possibility of their rotation. The second end 10 of the turbine apparatus to the suction pipe leading to the chamber 1 is inseparably connected with the suction pipe 11, which is made of direct flow. flow This makes it possible to increase the throughput and the specific power of the hydraulic machine, thus. which significantly expands its operational capabilities, Water from a pressure water supply (not shown) under which allow it to be used in a wide pressure of the upper beef through the needle direction- range of pressures. In addition, in the design, the hydraulic device Z is fed into the turbine chamber 1, the helical turbine chamber of the tilting machine performs the function of a helical hollow cylinder at the same time and the function of the impeller chamber, the core. thanks to which its dimensions are reduced to the size of the water consumption, which is supplied, is regulated by the diameter of the impeller, at the same time, the nominal value of the drive 4, which opens or closes, the inner diameter of the turbine chamber is equal to the guiding device 3. Next, the flow of water, moving diameter of the impeller. This also contributes to the reduction in the size of the helical trajectory in the helical cavity of the turbine chamber 1 along the structure and, accordingly, the space between the loparats of the main unit of the hydraulic machine - the hub assembly 9 of the impeller 6, exits from the other end to convert the hydraulic water pressure in 10 screw turbine chamber 1 and due to suction mechanical energy. Placement of the guide, the apparatus pipe 11 goes to the lower beef. and in the general layout of the hydraulic machine. Passing through the impeller 6 and flowing around it in front of the turbine chamber, it provides a supply to the blade 9, the water gives the impeller water energy with minimal energy losses. pressure and high-speed pressure, which turns into

Due to the new layout of individual nodes, hydro-mechanical energy in the form of torque. tires, making the turbine chamber in the form of screws. In this case, an optimal line of water flow is obtained, in which the operation of the hydraulic machine in pumping mode significantly improves the hydrodynamic characteristics - mechanical energy is transferred to the impeller of the flow due to the reduction of the number of turns b, which, rotating in the opposite direction, overflows in the flow part of the hydraulic cars. gives energy to the reverse flow of water.

This is possible due to the fact that the flow of water, passing through the hydraulic machine, which is claimed, is compadable through the flow part, is subject to only partial deformation and is characterized by a high flow rate, namely, smooth flowability and specific power, thanks to which thanks to the guiding device and movement along the screw train, it can be used in a wide range of pressures, for example, from 40 to 500 m. General gaba - additional construction works. The use of machine hydritis (compared to the prototype) of the reduced-size machine, which is declared, in the composition is hydrinated two to three times, and the efficiency increases by 1-295. of the power equipment of HPPs and GANPs will give a mo-

Relatively small dimensions, as well as the ability to efficiently use the energy of the hydraulic machine's displacement rivers in any simple and to build power plants with smaller dimensions trench layout without increasing the construction time of the HPP building. tines allow the machine to be used as well. The industrial applicability of the device, which is claimed to be low-pressure hydroelectric power stations instead of complex capsules, is confirmed by the possibility of making them hydro units. At the same time, the deepening of the work on the known equipment in the conditions of the industrial wheel relative to the level of the lower beef from my production using the known method of avoiding the cavitation mode does not require rials and adjustments.
