摘要：In this paper,a novel swing vane rotary compressor(SVC)was introduced,which had significant advantages-simple mechanism,reduced frictional loss,reliable operation,and a comparatively higher compression *** on the swing vane compressor geometry model,thermodynamic model and kinetic model,the mathematical model of optimum design was established,and further theoretical and experimental studies were *** length of the cylinder,radius of the rotor and cylinder were defined as design variables and the reciprocal of EER as objective *** complex optimization method was adopted to study the structure of the swing vane *** theoretical model could provide an effective method for predicting compressor performance,which would also contribute to structural optimization of the *** study shows that the friction loss of the compressor are greatly reduced by optimized design in a given initial value,and the EER increased by 8.55%.

摘要：针对同步回转式空气压缩机气缸内部泄漏通道多、间隙相对长度较大的特点,建立了系统泄漏模型,分析了各个泄漏通道的几何特点、运动特征和压差与泄漏量之间的关系。以给定排气量的同步回转式空气压缩机为例,模拟其各个泄漏通道的泄漏量,结果表明排气腔高压空气的轴向泄漏最大。针对在保证压缩机性能的基础上减少泄漏量的优化设计问题,对各泄漏通道的间隙进行了分析。研究结果为该类压缩机的设计提供了理论依据。

摘要：为了减小摩擦磨损,提高整机性能和效率,针对同步回转式压缩机滑板运动学机构进行了分析,找出了滑板的运动规律和滑板位置的几何关系,详细推导了滑板运动的速度和加速度的计算公式,并研究了滑板运动的速度和加速度随转角变化的关系.结果表明,滑板运动的速度随倾斜角增大而减小,加速度随倾斜角增大而增大,所以合理选择滑板倾斜角可大大降低摩擦磨损,提高可靠性.研究结果为滑板的可靠性设计及同步回转机械的整体优化提供了数学基础.
