Abstract

A magnetic levitation screw type gas expander is characterized in that the magnetic levitation screw type gas expander is at least formed into a whole through a machine body part (1), a driving rotor (2), a driven rotor (3), a magnetic coupling (7), a radial permanent magnet bearing (8), a bidirectional permanent magnet axial thrust bearing (9) and other parts. The magnetic levitation screw type gas expander has the beneficial effects that the friction power consumption of a rotary moving part of the expander is eliminated, oil-free lubrication operation is realized, zero leakage is achieved, and the performance and reliability of the expander are greatly improved.

Description

technical field [0001] The invention relates to a screw type gas expander in the field of gas expanders, in particular to a magnetic levitation screw type gas expander. Background technique [0002] In the field of gas expanders, screw gas expanders are widely used in power conversion of low-grade heat sources, such as industrial waste heat power recovery, solar energy utilization, geothermal power generation, ocean temperature difference power generation; and power recovery in decompression projects, such as water steam expander etc. [0003] The screw type gas expander utilizes a pair of intermeshing driving rotor 2 and driven rotor 3 with a specific convex and concave tooth shape installed in the body 102 to drive the rotor 2 to rotate during the process of high-pressure gas entering, expanding and discharging the gas medium and output power. [0004] Depend on figure 1 and figure 2 , the screw type gas expander is at least composed of body 102, intake end seat 103, ...
