双圆弧齿轮泵不同工况下流量特性分析

摘要：为分析不同工况下的双圆弧齿轮泵流量特性，使用AMESim软件对双圆弧齿轮泵进行精确建模，设定不同转速、负

载压力和气体质量分数并分析其瞬时出口流量和出口流量脉动率。结果表明：转速与瞬时出口流量呈正相关，转速为

3000r/min时的平均出口流量是转速为1500r/min时平均出口流量的2.17倍；负载压力与瞬时出口流量呈负相关,负

载压力为6MPa时的平均出口流量较负载压力为2MPa时平均出口流量减小0.621L/min；在转速为3000r/min、负载

压力为2MPa时，出口流量脉动率最小；出口流量脉动率与转速呈负相关，与负载压力呈正相关。油液的气体质量分数

增大会加剧双圆弧齿轮泵空化现象，对流量特性造成不利影响。
