Stability Analysis And Optimal Design For The Transmission System Of ZHL1400-60°High-Eiffciency Continuous Centrifuge

The centrifuge is a post-processing equipment in the production process,which are widely used in chemical lines, pharmacy, light industry, foodengineering, especially suitable for the separation in the sugar refinery on thecream A and B. With the development of science and technology, the separationtechnology has set forth stricter requirements for the continuity, efficiency andstability of separation process. The tensioning device is the key component ofZHL1400-60o highly-active continuous centrifuge, its ability of deformationcompensation not only concerns the production capacity and technology effect ofcentrifuge, but also largely determines its service life. In-depth analysis of thestress intensity, displacement size and vibration characteristics of the tensioningdevice in working condition, has a strong engineering practical significance.The main contents and conclusions in this paper are as follows:(1) Through the relevant movement of centrifuge, the analysis of specificdistortion compensation of the tensioning device is accomplished, as a basis forits finite element analysis.(2) The static analysis of tensioning device is achieved, including thedeformation compensation amount, stress and strain. Meanwhile, the parametersthat affect tensioning device are analyzed, in order to identify those which bringmore stable effect to the deformation compensation of tensioning device.(3) The modal analysis and harmonic response analysis of tensioning deviceare accomplished, and the natural frequency and amplitude changes has beencalculated, as well as the relationship between parameters and natural frequency.In this paper, the deformation compensation amount and its actual error oftensioning device is researched through static and dynamic analysis. Theparameter analysis is applied to propose those which are useful for optimization.Among those parameters, the spring pitch diameter and diameter changes affectstoo greatly to deformation compensation, which is not conducive to the stabilityof the drive equipment. The deformation compensation change according tospring length is more stable, which can be adopted as the basis for optimization,in order to improve the stability of compensation amount and transmission. Thefore10order natural frequencies are gained by modal analysis, to avoidresonance, as well as the displacement and stress amplitude at each order. The research in this paper has accumulated effective data for the structural analysisand optimization of ZHL1400-60°highly-active continuous centrifuge.
