Magnetic levitation single shaft direct drive compressor

Abstract

The invention discloses a magnetic suspension uniaxial direct-driven compressor which comprises two parts, namely a rotor system and a stator system, wherein the rotor system comprises a rotor of an axial magnetic bearing, a left radial displacement sensor detection ring, a rotor of a left radial magnetic bearing, a middle radial displacement sensor detection ring, a rotor of a middle radial magnetic bearing, a rotor of a motor, a pressure ring, a rotor of a right radial magnetic bearing and a right radial displacement sensor detection ring which are sequentially arranged on a screw shaft; the stator system comprises a stator of the axial magnetic bearing, a stator of the left radial magnetic bearing, a stator of the middle radial magnetic bearing, a stator of the motor and a stator of the right radial magnetic bearing which are sequentially arranged on a machine base; and non-mechanical contact magnetic suspension is realized between the rotor system and the stator system through the axial magnetic bearing, the left radial magnetic bearing, the middle radial magnetic bearing and the right radial magnetic bearing. The magnetic suspension uniaxial direct-driven compressor disclosed by the invention has the advantages of compact structure, energy conservation, environmental protection, high operation efficiency and high reliability.

Description

technical field [0001] The invention relates to a non-contact suspension support technology using a magnetic bearing, in particular to a magnetic suspension single-shaft direct drive compressor. Background technique [0002] With the continuous improvement of living standards, people's demand for energy (especially oil resources) is gradually increasing. Since domestic oil production is far from meeting consumer demand, the contradiction between energy supply and demand has become increasingly prominent, and energy has gradually become the bottleneck of my country's rapid economic development. Petroleum is not only the pillar energy of the national economy, but also the strategic energy of national defense. In order to meet the domestic consumption demand, my country's annual oil imports from abroad account for more than half of the total domestic consumption level. After overseas crude oil is transported to the port by tanker, it is transported to the refinery through the ...
