Abstract

The invention provides a magnetic levitation system detection method and device, a storage medium, a processor and a magnetic levitation compressor. The magnetic levitation system comprises a spindle,a motor, an electromagnetic bearing and an auxiliary bearing, the motor works to drive the spindle to rotate, the electromagnetic bearing and the auxiliary bearing are arranged on the spindle, the radius of the electromagnetic bearing is larger than that of the auxiliary bearing, and the detection method comprises the steps that whether the electromagnetic bearing stops working is detected; whenit is detected that the electromagnetic bearing stops working, the spindle is controlled to rotate at a preset rotating speed; the working current of the motor is detected; and the state of the auxiliary bearing is detected according to the working current. As the working current of the motor is increased due to the fact that the auxiliary bearing is blocked or jammed, the state of the auxiliary bearing is determined according to the working current of the motor, the state detection efficiency of the auxiliary bearing is improved, the state of the auxiliary bearing is detected in real time, and accurate maintenance is carried out.

Description

technical field [0001] The present application relates to the technical field of magnetic levitation, and in particular, relates to a detection method, device, storage medium, processor, and magnetic levitation compressor of a magnetic levitation system. Background technique [0002] In the magnetic levitation system, the main shaft relies on electromagnetic bearings to achieve levitation operation. When the suspension fails, the main shaft hits the electromagnetic bearing, causing damage to the entire magnetic suspension system. In order to protect the electromagnetic bearing, the magnetic suspension system usually designs auxiliary bearings to protect it. [0003] There are many forms of auxiliary bearings, such as ball bearings, sliding bearings, etc., which can rotate freely and smoothly. When the high-speed main shaft fails to suspend for some reason, the main shaft will fall freely and hit the auxiliary bearing, and the auxiliary bearing will rotate with the main shaf...
