| Abstract: | Pressures between two cylinders in the differential pressure air compressor exist interaction. In order to understand the impact and improve its work efficiency ,based on the introduction of the structure of the cylinders and piston of type CZ60/30 marine air compressor and its working principle, a mathematical model about the relationship between the pressure in cylinders and time was set up. Then, a simulation has been carried out through MATLAB. According to the results, the consequences of the clearance height caused to pressure were analyzed and the curves of the pressure and the differential pressure and time were proposed. A basic theoretical foundation was provided to develop a more efficient type of air compressor and analyze accidents. |
