Embodiment Construction

[0011] exist figure 1 Among them, the stator (1) is placed inside the rotor (2), and there are nozzles (3) on the stator (1). There can be multiple nozzles (3), which should be evenly distributed so that the rotor (2) can be affected by Even force.

[0012] The cross-sectional structure of the present invention is as figure 2 As shown, from top to bottom are rotating shaft (4), rotor upper cover (5), and rotor (2). The stator (1) is placed inside the rotor (2), there are nozzles (3) and guide rings (8) on the stator (1), there are air pipes (7) inside the stator (1), and the inside of the rotor (2) is covered with airflow rings (6), the distance between the airflow rings close to the nozzle (3) is small, and the distance between the airflow rings away from the nozzle (3) is large.

[0013] When working, the gas is passed from the air pipe (7) to the nozzle (3), and the nozzle (3) is sprayed to the inner side of the rotor (2), because the airflow ring (6) covering the inner...

Abstract

The invention provides an annular Tesla turbine which is characterized in that a rotor is in a ring shape, a stator is cylindrical and is arranged in the rotor, airflow rings are fully distributed inside the rotor, the space between the airflow rings adjacent to a nozzle is smaller, the space between the airflow rings far away from the nozzle is larger, and the nozzle is used for spraying air to the rotor along the tangential direction of the ring of the rotor. Since the airflow rings fully distributed inside the ring can be used for greatly increasing the contact area between the ring of the rotor and airflow; according to a boundary layer effect, the ring of the rotor can be driven to rotate by the airflow, so that the rotation of the rotor is realized; the airflow rings inside the ring of the rotor of the annular Tesla turbine are used for replacing the thin disc of a traditional Tesla turbine, the airflow rings and the ring of the rotor can be manufactured into a whole, or the airflow rings are supported and fixed on the ring, so that the airflow rings have rigidity better than that of the thin disc and have less possibility of deformation, and thus the rotor with a greater diameter and less possibility of deformation can be manufactured; and the power is increased, the efficiency is improved, and the operation is 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 an annular Tesla turbine, the annular Tesla turbine rotor is circular, the stator is cylindrical, the stator is placed inside the rotor, ...
