Problems solved by technology

When some manufacturing process causes a large batch of compressors to have a gap between the rotor and the stator that does not meet the requirements, it is necessary to screen out the compressors with a gap between the rotor and the stator that do not meet the requirements from the large batch of compressors. Some methods can only be inspected after the roof cover, which increases the cost of heavy work

Embodiment Construction

[0028] In order to allow those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 2 As shown, a gap detection device between the compressor rotor and the stator includes a power supply device 1 for supplying power to the compressor, an acceleration sensor 2 for testing the acceleration of the compressor, and is used to judge the gap between the compressor rotor and the stator. Whether the gap is qualified processor 3 and the acquisition module 4 for dynamic acquisition of the compressor acceleration signal of the acceleration sensor 2 test, the acquisition module 4 is arranged between the acceleration sensor 2 and the processor 3, by the processor 3 The collected dynamic signal is decomposed into acceleration information of different frequency bands.

[0030] The device has low cost, strong practicability, and wid...

Abstract

The invention discloses a method for detecting a clearance between a rotor and a stator of a compressor. The method comprises the steps of: S1, acquiring acceleration information of compressors which are qualified products and have clearances between rotors and stators conforming to requirements; S2, inputting the acquired acceleration information of the compressors into a processor to serve as reference information; S3, and acquiring acceleration information of a compressor to be tested, comparing the acceleration information with the reference information, and judging whether a clearance between a rotor and a stator of the compressor is qualified, so as to determine whether the compressor is a qualified product. The invention further discloses a device for detecting the clearance between the rotor and the stator of the compressor. According to the method and the device, a top cover of the compressor does not need to be turned off from a compressor shell body, the efficiency of judging whether the clearance between the rotor and the stator in the compressor shell body conforms to the requirement is improved, the production cost is saved, the rework cost is decreased, the testing efficiency is improved, the method and the device are suitable for batched compressor detection, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of compressor testing, and in particular relates to a method and device for detecting a gap between a compressor rotor and a stator. Background technique [0002] In the field of compressor production technology, the gap between the rotor and the stator in the compressor housing needs to be tested after the compressor is produced to ensure that the gap between the rotor and the stator meets the requirements of the industry and the quality of the compressor. Existing compressor manufacturers mainly check the gap between the rotor and the stator after the production of the compressor in the following two cases: one case is that the top cover of the compressor is not welded, and the gap sheet can be directly used for inspection; Another situation is that the compressor has been assembled, that is, the compressor shell and the top cover have been welded and fixed, and the top cover of the compressor can only be ...
