Abstract

The invention discloses a device for testing the port ring deformation and the rotor dynamic reflection of a large air-separation impeller compressor, and relates to the technical field of air-separation compressors. The device is characterized in that a probe is fixed at one end of a probe connecting rod and comprises a probe mounting surface and a probe connecting rod surface; a connecting rod bracket adjustably fixes the other end of the probe connecting rod and is detachably fixed on a base; the base is detachably fixed on a balancing machine and provided with a bottom plate and a connecting rod bracket fixing cylinder, wherein the bottom plate and the connecting rod bracket fixing cylinder are integrally molded; and probe is provided with an eddy current sensor, and the port ring deformation and the rotor dynamic reflection of the large air-separation impeller compressor are acquired according to data measured by the eddy current sensor on the probe. The device is accurate in measurement data, provides data for the design of the large air-separation impeller compressor, ensures a sealing effect of the large air-separation impeller compressor, reduces the energy consumption ofthe large air-separation impeller compressor and improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of air separation compressors, in particular to a test device for the deformation amount of the mouth ring of a large air separation impeller compressor and the dynamic deflection of the rotor. Background technique [0002] Air separation equipment is a set of industrial equipment that separates the various components in the air to produce oxygen, nitrogen and argon. The gases separated from the air also include rare gases helium, neon, argon, krypton, xenon, radon and so on. Among them, the air compressor plays a vital role. The design of the sealing gap of the impeller ring of the air compressor (referred to as air compressor) is very important. If the gap is too large, it will lead to large leakage, low efficiency and high energy consumption of the unit. At present, the design method of the sealing gap mainly adopts the method of calculating the empirical formula and querying the previous design data she...
