Abstract:: In order to solve the problem of valve difference caused by multistage small air compressor, the check valve was applied to carry out flow distribution, the influence of one-way valve parameters on the displacement and pressure pulsation of swash plate compressors was studied, and the valve parameters and compressor speed were optimized. Firstly, the mathematical models of single cylinder of one-way valve and swash plate air compressor were established, and then the influence rules of speed and valve parameters on compressor exhaust volume and pressure pulsation were obtained by changing the rotational speed, spring stiffness and preload of inlet and outlet valves. At the same time, in order to reduce the pressure pulsation and improve the exhaust volume as the goal, the particle swarm optimization algorithm was used to optimize the multistage air compressor, the optimal speed and valve parameters being be matched for each stage of the cylinder were obtained. Then the overall speed was determined, and the optimal parameters of each stage of the cylinder valve were optimized when the speed was consistent. The results showed that the parameters of the inlet valve had a greater effect on the exhaust volume and pressure pulsation than exhaust valve. Increasing the spring stiffness and preload of the inlet valve would reduce the pressure pulsation and exhaust volume, while increasing the stiffness and preload of the exhaust valve would increase the pressure pulsation. In addition, the pressure pulsation of all cylinders was reduced by 26.5% and 36.1% respectively, and the displacement volume increased by 66.9% and 48.9%, respectively.
