SZ110VF Twin-Screw Air Compressor Flow Field Noise Analysis
Taking SZ110VF upper screw air compressor as an example,a noise analysis method of flow field of twin-screw air compressor is introduced.First of all,the UG software uses the air compressor material characteristics,flow field characteristics and other parameters to construct a three-dimensional model of the air compressor flow field,through appropriate conversion,the model is imported into the FLUENT software in order to divide the model into a large number of grids,and then,based on this,the distribution of the broadband noise of the air compressor and the influencing factors of the distribution of the acoustic frequency level were analyzed,to find out the program that minimizes the noise in the flow field of the air compressor,i.e:The tooth top clearance is 0.2mm,the center distance of twin-screw is 81.2mm,and the rotational speed of twin-screw is at a relatively low level.
