Abstract

The invention discloses a load testing-analyzing method of a rotor compressor for a refrigeration plant. The load testing-analyzing method is characterized in that the amplitudes of two testing points are tested by an experiment, the finite element technology is utilized for calculating transfer matrixes of the displacement to all the testing points, caused by the force and moment on loading action points, and displacement matrixes of all the testing points, so that the loading value of the compressor can be obtained in a reversing manner. The loading value of the rotor compressor can be obtained by a simple and feasible testing method, so that the work stress of a pipe distribution structure can be analyzed and calculated conveniently.

Description

technical field

[0001] The invention relates to a method for testing and analyzing the load of a compressor used in refrigeration equipment, in particular to a method for testing and analyzing the load of a rotor compressor in refrigeration equipment. Background technique

[0002] For refrigeration equipment using rotary compressors, the current piping design is usually conservative, the length of the piping is very long, and the performance of the material is not fully utilized. Under the situation that the purchase price of copper pipes continues to rise, it brings great cost pressure to the enterprise. But even so, the occurrence of broken pipes cannot be prevented. The reason is that there is a lack of correct piping design methods, and there is a large blindness in piping design. At present, predicting the working reliability of refrigeration equipment piping through analysis and calculation is an effective way to ensure the reliability of the piping structure design sc...
