【摘要】：提出了一种新型多级斜盘柱塞式气泵,根据双向斜盘式气泵的结构特点及其柱塞的相对运动规律,将气泵内的气缸分成若干级,并在前、后气缸盖处通过单向阀配流,将同一级气缸并联连接,相邻级气缸串联连接,从而实现多级压缩。阐述了气泵的基本结构和工作原理,对气泵的运动特性进行了分析与计算,建立了气泵内气体压缩与膨胀热力过程的数学模型,并应用4阶龙格库塔法对其进行数值求解,分析了气泵工作过程中气体压力与温度两方面的热力特性,并从节省压缩气体指示功和降低排气温度两个方面分别对比分析了多级压缩相对于单级压缩的优点。
[Abstract]:A new type of multi-stage inclined disk plunger type air pump is proposed. According to the structural characteristics of the bidirectional inclined disc type air pump and the relative motion law of the plunger, the cylinder in the pump is divided into several stages, and the flow is distributed through the unidirectional valve at the front and back cylinder head.The parallel connection of the same primary cylinder and the series connection of the adjacent stage cylinder can realize multistage compression.In this paper, the basic structure and working principle of the gas pump are expounded, the motion characteristics of the gas pump are analyzed and calculated, the mathematical model of the gas compression and expansion thermodynamic process in the air pump is established, and its numerical solution is carried out by using the 4-order Runge-Kutta method.The thermodynamic characteristics of gas pressure and temperature in the working process of gas pump are analyzed. The advantages of multistage compression over single stage compression are compared and analyzed from the aspects of saving the indicated work of compressed gas and reducing the exhaust temperature.
