| Scroll compressors are highly anticipated positive displacement compressors in recent years.It has a high rate of efficiency,especially as the country actively manages air quality.Under the background of large-scale expansion of coal in the north,scroll compressors have become popular in the field of air source heat pump water heaters.Because of its principle requirement,the scroll compressor must have a mechanism for preventing the rotation and rotation of the rotor.The most common is the Cross-slip ring,which is a key component to ensure the basic function of the scroll compressor,the cross-slide ring and its failure modes.However,it is far less than the orbiting scroll.With the rapid development of computer technology,finite element analysis can help analyze and describe the stress and deformation of components in the actual operation of scroll compressors.It also seeks to improve the direction,improve the quality of parts design,and shorten the development cycle.Based on the working principle of scroll compressor and theoretical mechanics,combined with the working process and characteristics of scroll compressor,taking a scroll compressor in the market as an example,after briefly introducing the principles of scroll compressor and internal forces,The main work was as follows:1.Mathematical models of two kinds of scroll-slip rings for scroll compressors were established respectively,and they were solved using ANSYS finite element software and stress and deformation analysis;2.Analyzed the influence of the weight and raw material properties of Cross slide ring on the stress and deformation after loading,and obtained the relative formula of the two;3.Analyze and calculate the difference between the three new refrigerants and the R410A gas force and the effect of gas force on the cross slip ring;Through these efforts,we hope to provide a theoretical basis for the development of new products for Scroll Compressor R&D companies and reduce the failure of Cross slip ring. |
