Problems solved by technology

Although the turbine has the advantages of simple structure, compact volume, and low cost, it has not been widely used due to the disadvantages of insufficient rigidity and easy deformation when the disc size is large, large eddy current deflection between discs, and large vibration.

Embodiment Construction

[0008] exist figure 1 Among them, there are nozzles (1) inside the rotor (2), and there can be multiple nozzles, which should be evenly distributed so that the rotor (2) can be evenly stressed when the air is sprayed out. The cross-sectional structure of the rotor (2) is as follows figure 2 As shown, from top to bottom are the rotating shaft (3), the rotor upper cover (4), the ring (5), the rotor lower cover (7), wherein the inner side of the ring (5) is distributed with annular slices (6), The rotor lower cover (7) has an exhaust port (8), and the air pipe (9) extends into the rotor (2) from the exhaust port (8) and is connected to the nozzle (1).

[0009] When working, the gas is passed from the air pipe (9) to the nozzle (1), and the nozzle (1) is sprayed to the inner side of the ring (5), and the air flow will form a vortex under the guidance of the inner side of the ring (5). The annular sheet (6) inside the ring (5) greatly increases the contact surface between the rin...

Abstract

The invention relates to an annular tesla turbine, which is characterized in that a rotor is made into a circular ring; annular slices are uniformly distributed on the inner side of the ring; a nozzle stretches into the inner side of the circular ring and jets air for the circular ring along a tangential direction of the circular ring; a vortex is formed by airflow under the guidance action of the inner side of the circular ring; and due to the annular slices uniformly distributed on the inner side of the circular ring, a contact surface of the circular ring and the airflow is greatly increased, so the circular ring is driven by the airflow to be rotated together according to a boundary layer effect, and thus the rotation of the rotor is realized. According to the annular tesla turbine, the annular slices on the inner side of the circular ring replace a thin disk of a conventional tesla turbine, and the annular slices and the circular ring can be made into a whole, or the annular slices are supported and fixed on the ring, so that the stiffness of the annular slices is better than that of the thin disk, the annular slices are not easy to deform, the rotor can have larger diameter and is not easy to deform, and thus the power is increased and the operation is more stable and reliable.

Description

Technical field [0001] The invention relates to an annular Tesla turbine, which belongs to the technical field of steam turbines. Background technique [0002] The Tesla turbine, also known as a bladeless turbine, is shaped like a shaft with multiple smooth and thin discs fixed at a certain distance. The airflow hits these discs from a tangential direction, and the boundary layer effect drives these discs and the shaft Turn together. Although the turbine has the advantages of simple structure, compact volume, and low cost, it has not been widely used because of the disadvantages of insufficient rigidity and easy deformation when the disk size is large, large eddy current deflection between disks, and large vibration. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a ring-shaped Tesla turbine. The ring-shaped Tesla turbine makes the rotor into a ring, and the inner side of the ring is evenly covered ...
