Mathematical modeling and analysis of electromagnetic direct drive air compressor

Abstract

Abstract To accurately simulate the motion characteristics of a reed valve and the changes in flow field in an exhaust chamber, a fluid-structure coupling model of an electromagnetic direct drive air compressor during the exhaust process was established and simulated. The alteration of the flow field within the exhaust chamber is under examination. The transient numerical simulation of the flow field in the exhaust procedure is conducted to reduce the computational model's time complexity and provide an immediate analysis of the exhaust processThis paper explores the effects of altering valve lift and relative pressure loss given different valve parameters and exhaust pressure levels. The findings reveal that when the valve plate thickness is 0.2mm and the valve section width is 3.5mm, the airflow hindrance is significantly minimized. With the valve plate unloaded, the gas flow restriction's impact on gas flow is negligible. This paper presents a theoretical basis for designing exhaust valves for electromagnetic direct-drive air compressors.
