Description
Technical Field
The invention relates to the technical field of detection, in particular to a method and a device for measuring a refrigeration system pipeline.
Background
In view of the background of continuous global warming, the world countries have continuously introduced laws and regulations for limiting the emission of greenhouse gases, and room air-conditioning products contain a large amount of refrigerants, wherein the refrigerants contain a large amount of fluorinated gases, the equivalent of carbon dioxide of the fluorinated gases is large, and the fluorinated gases have serious damage to the earth's ozone layer. Therefore, governments around the world are restricting the use of refrigerants with large carbon dioxide equivalent. Therefore, a large number of air-conditioning manufacturers abandon the use of freon refrigerant, and instead use a refrigerant with a low carbon dioxide equivalent. But these refrigerants are basically combustible. In the case of a malfunction or an error, the air conditioner using the refrigerant may be ignited by the leaked flammable refrigerant, thereby causing a fire or explosion.
Because the refrigerant is filled in the refrigeration circuit consisting of the refrigeration pipelines, the refrigerant in the refrigeration pipelines is under higher working pressure, and the pipelines vibrate because the compressor in the refrigeration circuit continuously compresses the refrigerant and enables the refrigerant to circulate in the pipelines. The pipeline is easy to break or the welding point is unreliable due to long-time excessive vibration, so that the combustible refrigerant is leaked, and if the leaked combustible refrigerant is ignited, the danger of fire or explosion can be generated. Therefore, vibration measurement and amplitude detection of the refrigeration circuit piping are also a need in the whole refrigeration industry, especially in the development phase of products; excessive vibration of the pipeline can seriously affect the service life of the product.
Currently, an infrared dotting test method or a mechanical pointer mode is mainly adopted. During measurement, a graduated scale is fixed in a determined direction on a measured object or a measured point, a beam of focused infrared light in the horizontal direction is struck from the outside of the measured point to the zero point position of the graduated scale, and when vibration occurs, the moving distance of the infrared light on the graduated scale is directly read. A triangular gauge is fixed in the vertical direction of the vibration of the tested pipeline, and the amplitude is calculated by a mathematical method. The method has inconvenient test point arrangement and inconvenient data structure accuracy due to the arrangement.
