新型高压低重斜盘式压缩机结构性能研究

Research on Performance of New High Pressure and Low Weight Splate Compressor

针对空气压缩机重量重、气压低无法较好地搭载在机载武器中的问题,提出了一种新型的高压低重斜盘式压缩机。首先,优化传统单级活塞式结构以满足轻量化要求。其次,通过多级压缩的方式,将气缸分为若干级,相同级并联,相邻级串联,且每级气缸直径逐渐缩小,较单级压缩可提高15倍左右且持续可控。通过Matlab建立模型分析运动过程中压强、速度、加速度随转角的变化曲线。最后,针对多级压缩产生的热量问题,采用分级冷却的方式处理,该方式能有效地降低排气温度、提高工作效率。利用龙格库塔法进行热力特性分析与Ansys仿真,验证冷却管路设计。最终实现高气压、轻量化与高效并存的压缩机。

The problem that the air compressor is heavy and the air pressure is low cannot be mounted on the airborne weapon,a new type of high pressure low swash plate compressor is proposed.First,Optimizating the traditional compression structure to meet the requirements of lightweight.Nextly,Compression by multi-stage compression,compared with conventional compressor’spressure increased by about 15 times,also can control it more stably and reliably.The model was established by Matlab to analyze the curves of pressure,velocity and acceleration with the rotation angle during the motion.Finally,By grading cooling,after each stage of compression after staged compression,cooling is performed,the temperature of the compressed gas is lowered,Using the Runge-Kutta method and Ansys simulation to verify the design of the cooling circuit.The ultimate realization of high pressure,lightweight and efficient coexistence of compressors.
