ORC circulation system based on static pressure air bearings

The invention discloses an ORC circulation system based on static pressure air bearings, and relates to the technical field of low-temperature power generation. The invention aims to provide the oil-free and leakage-free ORC circulation system with high working efficiency. The ORC circulation system based on the static pressure air bearings comprises a liquid storage tank, a refrigerant pump, an evaporator, a radial expansion generator set, a condenser and a parallel flow device, wherein the radial expansion generator set comprises a generator housing, and a variable-speed permanent magnet generator and a turbine are integrally arranged in the generator housing; a rotor in the variable-speed permanent magnet generator rotates along with a rotation shaft, and the rotation shaft is supportedby the two static pressure air bearings; an insulated cooling system is arranged in the radial expansion generator set and comprises a jet flow ring, a liquid storage ring, an insulated gas chamber and an insulated liquid ch
