Theoretical Study of the Parallel Inflatable Process for Star Type Compressor Used in Ships and Warships
摘要
Abstract
In order to study working mechanism of the parallel inflatable process for star type compressor used in ships and warships, the numerical calculation model of the parallel inflatable process was set up in this paper based on the working principle of the star type compressor. By using this model, the thermal performance of the parallel inflatable process was studied and the influence law of the parallel compressor numbers and pneumatic parameters on the pressure inside the tank at any time, the actual displacement of the compressor and inflation time are obtained. Through the analysis found that: the pressure inside the tank will increase more quickly and the instantaneous actual displacement of the compressor will decrease when used several star type compressors connection in parallel to achieve the inflatable process. With the increase of the parallel compressor numbers, the increased value of the pressure inside the tank is increased linearly, but the decreased value of the instantaneous actual displacement for single compressor and the inflation time will gradually decrease and flatten out. With the increase of the initial pressure inside the tank, the instantaneous pressure during the inflatable process will increase and the instantaneous actual displacement of the compressor will gradually reduce. The higher the initial pressure, the smaller decreased value of the instantaneous actual displacement and the smaller times needed for inflation. All these analyses can provide theoretical basis for the optimized optional of the compressor used in oceaneering.关键词
