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 that after the core assembly of the existing magnetic levitation centrifugal compressor is completed, the compressor needs to be energized and suspended to check whether there is interference between the rotor and the stator; and a simulation detection suitable for the assembly process of the core of the magnetic levitation centrifugal compressor is provided. , Simulate the extreme situation where the rotor suddenly loses control during operation, the rotor falls on the protective bearing, and when the rotor is at the left or right extreme position in the axial direction, when the rotor rotates at the extreme position, check the rotor parts such as the impeller and the stator parts such as the volute. Whether there is still a gap, and there is no interference.

[0041] The 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-s...

Abstract

The invention belongs to the technical field of compressors, and discloses a rotation detection device and a detection method for a magnetic levitation centrifugal compressor. The rotation detection device comprises a T-slot mounting table 1, a support base 2, and a compressor rotating body 3; the support There are a plurality of seats 2, which are respectively installed on the T-slot mounting platform 1; the compressor rotating body 3 is fixedly supported by a plurality of supporting seats 2; the compressor rotating body 3 is used to fix the compressor body, so that the compressor The body rotates 360° forward and reverse around the center of rotation of the compressor, which can simulate the extreme situation that the rotor suddenly loses control during operation, and the rotor falls on the protective bearing. , Check whether there is interference between rotor parts such as impeller and stator parts such as volute, and improve detection efficiency.

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 suspension centrifugal compressor. Background technique [0002] The magnetic levitation centrifugal compressor is a centrifugal compressor that adopts a number of advanced technologies such as high-speed motor direct drive, magnetic levitation bearing support, and ternary impeller core structure. The magnetic suspension bearing system suspends the rotor between the magnetic poles of the stator through controllable electromagnetic force, realizes the operation without mechanical contact between the rotor and the stator, and has the advantages of no wear, no lubrication and long 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 rotor when the magne...
