【摘要】：柱塞泵是最常见类型泵中的一种,直线电机柱塞泵可以实现电力到液压力的直接输出,不仅可以合理地减少动力系统的负荷,并且可以很大程度上减少了柱塞泵的体积和繁杂的机械传动机构,对于高效率,低能耗,高环保的各种机械设施有着迫切的应用需求。直线电机在国内外很多领域中已经得到较为广泛的研究和应用。在动力端如果用直线电机直接驱动柱塞泵的活塞杆,泵的结构可进行较大的简化,同时结构也会紧凑,效率将会提高。本文主要的研究工作就是研究和分析了直线电机柱塞泵的工作原理,将直线电机与柱塞泵的活塞杆直接连接并进行无波动分析,针对直线电机的运动情况阐述了柱塞泵无流量波动的运动特性,提出了采用双直线电机双作用驱动柱塞泵的理论,在理论上实现了吸入和排出总流量的恒定和压力的无波动。并进行了直线电机柱塞泵整体方案的设计和对柱塞泵控制系统的选用,进而利用计算机进行可行的仿真模拟。利用AMESim软件对柱塞泵系统的各部分进行了建模仿真,模拟了柱塞泵的实际工作过程,分析了泵在工作过程中流量和压力的输出特性。通过仿真实验验证了直线电机柱塞泵实际运用的可行性。
[Abstract]:Plunger pump is one of the most common type pumps. Linear motor piston pump can realize the direct output of electric power to hydraulic pressure, not only can reasonably reduce the load of power system. And it can greatly reduce the volume of piston pump and complex mechanical transmission mechanism, for high efficiency, low energy consumption, high environmental protection of various mechanical facilities have an urgent application needs. Linear motor has been widely studied and applied in many fields at home and abroad. If the piston rod of the piston pump is driven directly by linear motor at the power end, the structure of the pump can be greatly simplified, at the same time the structure will be compact and the efficiency will be improved. The main research work of this paper is to study and analyze the working principle of linear motor piston pump. The linear motor and piston rod of piston pump are connected directly and analyzed without fluctuation. According to the motion of linear motor, the motion characteristics of piston pump without flow fluctuation are expounded, and the theory of using double linear motor to drive piston pump is put forward. In theory, the constant suction and discharge total flow and no fluctuation of pressure are realized. The design of the integral scheme of linear motor piston pump and the selection of piston pump control system are carried out, and the feasible simulation is carried out by using computer. The modeling and simulation of various parts of piston pump system are carried out by using AMESim software. The actual working process of piston pump is simulated and the output characteristics of flow and pressure are analyzed. The feasibility of practical application of linear motor piston pump is verified by simulation experiment.
