Abstract

The invention belongs to the technical field of new energy, and particularly relates to a compression and expansion integrated turbine unit. According to the technical scheme, the compression and expansion integrated turbine unit comprises an integrated rotor, and radial electromagnetic bearings and axial electromagnetic bearings are installed at the two ends of the integrated rotor correspondingly; the middle of the integrated rotor is provided with a first air cylinder in a sleeved mode; a second air cylinder is arranged at one end of the integrated rotor, and a third air cylinder is arranged at the other end of the integrated rotor; and the second air cylinder and the third air cylinder are connected with the radial electromagnetic bearing and the axial electromagnetic bearing respectively, and a motor is further installed between the third air cylinder and the integrated rotor. The invention provides the compression and expansion integrated turbine unit.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a compression-expansion integrated turbine unit. Background technique [0002] Compression and expansion are two opposite thermodynamic processes. Compression is to convert the mechanical energy input from the outside into the internal energy of the working medium, while expansion is just the opposite to convert the internal energy of the working medium into mechanical energy for external output. Turbomachinery has been developed so far. Human beings have developed and derived various types of compressors and expanders to meet the needs of different kinds of industrial applications. However, due to the influence of design parameters, application occasions and various limiting factors of size, there are few compression or expansion devices that can simultaneously meet complex and changeable application requirements. Some special applications, such as compressed air...
