Embodiment 1

[0114] Such as figure 1 As shown, a Tesla turbine comprising:

[0115] Shaft 100;

[0116]A housing 200 disposed on the rotating shaft 100, the housing 200 is provided with a medium inlet (not shown in the figure) and a medium outlet (not shown in the figure);

[0117] Several disks 300 are arranged in the housing 200, and several disks 300 are fixedly connected to the rotating shaft 100. A gap 400 is provided between every two adjacent disks 300 among the several disks 300. Each of the disks 300 is provided with at least one exhaust hole 301;

[0118] And, the thrust bearing 500 and at least two radial bearings disposed on the rotating shaft 100 are non-contact bearings.

[0119] In the embodiment of the present invention, the rotating shaft 100 of the Tesla turbine can be connected with the motor 3 , for example, the rotating shaft 100 is connected with the rotating shaft 310 of the motor 3 through the coupling 7 . Of course, the motor 3 can also be directly arranged on ...

Embodiment 2

[0143] The working process of the Tesla turbine is described in detail below.

[0144] As mentioned above, the thrust bearing in the Tesla turbine can use aeromagnetic hybrid thrust bearing, and the radial bearing can use aeromagnetic hybrid thrust bearing or aerodynamic and static pressure hybrid radial bearing. For the convenience of description, we define the bearings that can lubricate without the rotation of the rotating shaft 100 as hydrostatic bearings, and the bearings that can only work when the rotating shaft 100 rotates at a certain speed are defined as dynamic pressure bearings. According to this logic, the magnetic bearing and the gas static pressure bearing in the gas magnetic hybrid thrust bearing, and the gas static pressure bearing in the gas dynamic and static pressure hybrid radial bearing can all be called hydrostatic bearings; and the gas in the gas magnetic hybrid thrust bearing Both the hydrodynamic bearing and the gas dynamic pressure bearing in the gas...

Abstract

The invention provides a tesla turbine and a control method. The tesla turbine comprises a rotating shaft, a shell, a plurality of discs, a thrust bearing and at least two radial bearings; the shell is arranged on the rotating shaft, and a medium inlet and a medium outlet are formed in the shell; the plurality of discs are arranged in the shell, the plurality of discs are fixedly connected to therotating shaft, a gap is formed between every two adjacent disks of the plurality of disks, and at least one exhaust hole is formed in each of the plurality of disks; and the thrust bearing and at least two radial bearings are arranged on the rotating shaft, and the thrust bearing and the at least two radial bearings are non-contact bearings. According to the tesla turbine, non-contact thrust bearings of the thrust bearing and the radial bearings are adopted, the power loss of the tesla turbine on the bearings is reduced, so that the efficiency of the tesla turbine is improved.

Description

technical field [0001] The invention relates to the technical field of steam turbines, in particular to a Tesla turbine and a control method. Background technique [0002] A Tesla turbine is a bladeless turbine driven by the shear force of a fluid, it is called a bladeless turbine. The Tesla turbine applies the boundary layer effect. The fluid is affected by the viscous force and will form a thin boundary layer on the edge of the pipe wall or other objects. In the boundary layer, the flow velocity of the fixed surface is 0, and the farther away from the surface The greater the speed. Using this effect, the high-speed moving liquid can drive a set of discs to rotate. Tesla turbines can be up to 95 percent efficient, much higher than ordinary bladed turbines. [0003] Although the Tesla turbine has the advantage of high efficiency, due to the low torque of the Tesla turbine and its high sensitivity to mechanical friction, the existing Tesla turbine has a large power loss on...
