摘　　要：提出了一种新型叠滚型结构的二维(2D)活塞泵,该泵的活塞在连续旋转时同时进行往复运动。配合吸排油机构,其工作腔的容积随活塞的运动而变化,实现吸排油功能。在对活塞泵结构和工作原理进行分析的基础上,首先建立其数学模型,其次进行理论分析,最后搭建试验平台,测试了不同转速和负载压力下的容积效率和机械效率。试验结果表明:在负载压力为6 MPa时,转速从1 000 r/min提升至6 000 r/min,容积效率从88.5%上升至98%,机械效率从93%下降至74%;当转速为6 000 r/min时,负载压力从5 MPa提升至8 MPa,容积效率从98.3%下降至96.7%,机械效率从69%上升至79.1%,验证了理论分析的正确性以及叠滚型2D活塞泵的可行性。A new type of two-dimensional(2 D) piston pump with stacked-rolling structure was proposed, in which the piston reciprocates while rotating continuously. Cooperating with the oil suction and discharge mechanism, the volume of working cavity changes with the piston’s movement to realize the oil suction and discharge. Based on the analysis of the structure and working principle, a mathematical model was established, the theoretical analysis was carried out and an experimental platform was designed to test the volumetric efficiency and mechanical efficiency under different rotational speed and different load pressure. The experimental results show that when the load pressure is 6 MPa, the rotational speed increases from 1 000 r/min to 6 000 r/min, the volumetric efficiency increases from 88.5% to 98%, the mechanical efficiency decreases from 93% to 74%. When the rotational speed is 6 000 r/min, the load pressure increases from 5 MPa to 8 MPa, the volumetric efficiency decreases from 98.3% to 96.7%, the mechanical efficiency increases from 69% to 79.1%, which verifies the correctness of the theoretical analysis and the feasibility of the piston pump.
