Problems solved by technology

The inspection is completed through the control command. When mechanical interference is found, it can only be confirmed that there is interference, but it cannot be determined that the part of the compressor rotor and stator interferes. It needs repeated disassembly and rework and power-on suspension inspection to confirm. This inspection is extremely complicated. and long

Embodiment Construction

[0040] The invention solves the problem of checking whether there is interference between the rotor and the stator after the core assembly of the existing magnetic levitation centrifugal compressor is completed, and provides a simulation detection suitable for the assembly process of the core core of the magnetic levitation centrifugal compressor , to simulate the limit condition that the rotor suddenly loses control when it is running, and the rotor falls on the protective bearing, and when the rotor is at the left or right limit position in the axial direction, when the rotor rotates at the limit position, check the rotor parts such as the impeller and the stator parts such as the volute Is there still a gap, but no interference exists.

[0041] An embodiment of the present invention provides a rotation detection device for a magnetic levitation centrifugal compressor, such as figure 1 As shown, it includes a T-slot mounting platform 1, a support base 2, and a compressor rot...

Abstract

The invention belongs to the technical field of compressors, and discloses a rotation detection device and detection method for a magnetic suspension centrifugal compressor. The rotation detection device comprises a T-shaped groove mounting platform 1, supporting bases 2, and a compressor rotating body 3. There are multiple supporting bases 2 which are respectively arranged on the T-shaped groovemounting table 1; wherein the compressor rotating body 3 is fixedly supported by multiple supporting bases 2; the compressor rotating body 3 is used for fixing the compressor body and the compressor body can positively and negatively rotate around the rotation center of the compressor by 360 degrees; the limit conditions that the rotor is suddenly out of control during operation and falls on the protective bearing can be simulated, whether rotor pieces such as an impeller and stator pieces such as a volute interfere with each other or not is checked when the rotor is located at the left or right limit position in the axial direction and rotates at the limit position, and the detection efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a rotation detection device and a detection method for a magnetic levitation centrifugal compressor. Background technique [0002] The magnetic levitation centrifugal compressor is a centrifugal compressor that adopts many advanced technologies such as direct drive of high-speed motor, magnetic levitation bearing support, and three-dimensional impeller core structure. The magnetic suspension bearing system suspends the rotor between the magnetic poles of the stator through the controllable electromagnetic force, and realizes the non-mechanical contact operation between the rotor and the stator. It has the advantages of no wear, no lubrication and long service life. [0003] In the magnetic suspension bearing system, in order to improve the reliability of the whole system, a set of protective bearings is set up as a temporary support for the high-speed rotating rot...
