Method for Determining Best Piston Numbers of a Swash Plate Axial Piston Pump

Abstract

Abstract:

The main influencing factors of a swash plate axial piston pump's structure and properties were put forward, and correlation among the piston numbers and those main influencing factors was analyzed. A best program of the piston number was obtained by using the comprehensive factor evaluation method, which was a comprehensive weighted and comparison of every factor. For the K3V double-compound axial piston pump,the best piston number is as 9 using the above method. The method for determining the piston numbers provides the theory and method for selecting the best piston numbers of a swash plate axial piston pump.

Key words: swash plate axial piston pump;piston number;factor;comprehensive factor , evaluation

摘要：

给出了斜盘式轴向柱塞泵结构及性能的主要影响因素,分析了柱塞数与各因素之间的关联性。运用综合因素评价法，对各因素进行综合性加权比较，得出了柱塞数选取最佳方案。运用该方法确定了K3V型双联轴向柱塞泵设计中的最佳柱塞数(最佳柱塞数为9)。
