【摘要】：乳化液泵是高产高效综合机械化采煤配套设备中液压支架支护系统的动力源,在综采工作面中具有十分重要的地位。乳化液泵作为井下工作的重要设备,它的性能的好坏直接影响到综采效率的高低。随着煤矿综合机械化采煤技术的不断发展,要求乳化液泵的性能不断提高。在这种情况下,对乳化液泵的性能进行优化就变得非常重要。本课题主要是利用AMESim系统仿真学软件建立乳化液泵的仿真模型,从而对乳化液泵进行仿真分析。本文在对乳化液泵进行理论分析的基础上,在AMESim系统仿真学软件中建立乳化液泵的液压系统仿真模型,对乳化液泵的柱塞、曲轴和吸、排液阀的运动特性进行了研究分析,并且,研究了乳化液泵的流量和压力等动态特性；同时,通过对曲轴转速、吸排液阀阀芯质量和弹簧刚度的改变来研究影响乳化液泵性能的主要因素,并且,得出了不同参数下乳化液泵的流量特性曲线和容积效率,对乳化液泵的设计和研究具有十分重要的意义。
[Abstract]:Emulsion pump is the power source of hydraulic support support system in high yield and high efficiency comprehensive mechanized coal mining equipment and plays an important role in fully mechanized mining face. Emulsion pump is an important equipment for underground work. With the continuous development of comprehensive mechanized coal mining technology, the performance of emulsion pump is required to improve continuously. In this case. It is very important to optimize the performance of emulsion pump. In this paper, the simulation model of the emulsion pump is established by using the AMESim system simulation software, and the simulation analysis of the emulsion pump is carried out. Based on the theoretical analysis of the emulsion pump, the hydraulic system simulation model of the emulsion pump is established in the AMESim system simulation software. The plunger, crankshaft and suction of the emulsion pump are analyzed. The movement characteristics of the drain valve are studied and the dynamic characteristics such as the flow rate and pressure of the emulsion pump are studied. At the same time, through the crankshaft speed, suction valve valve core mass and spring stiffness changes to study the main factors affecting the performance of the emulsion pump, and. The flow characteristic curve and volumetric efficiency of emulsion pump under different parameters are obtained, which is of great significance to the design and study of emulsion pump.
