【摘要】：乳化液泵是为综采工作面的液压支架等提供动力的主要设备,由于乳化液泵主要用于综采工作面,其工作环境恶劣,灰尘、矿灰多,而且承受的外界负载大,需要连续不断的运行。所以,对乳化液泵的安全性、可靠性、稳定性等指标就非常严格。S375乳化液泵由英国RMI雷波泵站公司生产的,其结构简单、稳定、可靠、面维修等特点是国产乳化液泵无法达到的。为此,无论从实用性还是从科学性出发,开展对S375乳化液泵的研究工作,保障综采工作高效、安全、有序的进行是具有重要意义的,根据往复泵的设计标准,对S375乳化液泵结构及特性进行分析、设计和研制。本论文首先对S375乳化液泵的基本结构及其重要部件进行分析,通过它的实际工作情况分析了各部分结构的工作原理,并对乳化液泵的结构参数进行分析计算,以此确定它的基本结构参数。接下来对S375乳化液泵的运动进行分析,推导出数学建模,通过Matlab软件进行仿真,从而得到柱塞的运动规律。同时对乳化液泵的流量在不同滞后角条件下进行分析,推导出数学建模,并进行仿真分析,得到泵瞬时流量在不同滞后角下的脉动规律。经对比分析得出泵运动对流量脉动所造成影响。流量脉动必然对系统产生压力脉动,而压力脉动会对系统产生压力冲击,故进一步对泵的系统进行分析,建立起系统的模型,通过AMEsim软件对泵系统进行仿真分析,得到其压力冲击规律,通过与实际结论比对可知泵的基本性能参数符合要求。最后,对泵的两个重要部件曲轴、连杆分别进行静态分析和动态分析,通过有限元的仿真分析可以得出两个部件的结构设计合理,从而验证两个重要部件的结构参数设计符合理论要求。本论文对S375乳化液泵的参数及性能分析,是为了进一步设计、优化、研制S375乳化液泵提供一定的理论基础。
[Abstract]:Emulsion pump is the main equipment to provide power for hydraulic support in fully mechanized coal mining face. Because the emulsion pump is mainly used in fully mechanized mining face, its working environment is bad, dust and coal ash are much, and the external load is large. Therefore, the safety, reliability and stability of the emulsion pump are very strict. The S375 emulsion pump is produced by the UK RMI Leibo pumping Station Company. Its structure is simple, stable and reliable. Surface maintenance and other characteristics are beyond the reach of domestic emulsion pumps. Therefore, it is of great significance to carry out the research on S375 emulsion pumps from both practical and scientific aspects to ensure the efficient, safe and orderly operation of fully mechanized coal mining. According to the design standard of reciprocating pump, the structure and characteristics of S375 emulsion pump are analyzed, designed and developed. The working principle of each part of the pump is analyzed through its actual working conditions, and the structural parameters of the emulsion pump are analyzed and calculated to determine its basic structural parameters. Then, the movement of the S375 emulsion pump is analyzed. The mathematical modeling is deduced and simulated by Matlab software, and the movement law of plunger is obtained. At the same time, the flow rate of emulsion pump is analyzed under different lag angles, and the mathematical model is deduced, and the simulation analysis is carried out. The effect of pump motion on flow pulsation is obtained by comparison and analysis. Flow pulsation will inevitably produce pressure pulsation on the system, and pressure pulsation will produce pressure shock on the system. Therefore, the pump system is further analyzed, the system model is established, the pump system is simulated and analyzed by AMEsim software, the pressure impact law is obtained, and the basic performance parameters of the pump are compared with the actual results. Finally, the basic performance parameters of the pump meet the requirements. The static analysis and dynamic analysis of the two important parts of the pump crankshaft and connecting rod are carried out respectively. The structural design of the two components is reasonable through the simulation analysis of the finite element method. In this paper, the analysis of the parameters and performance of S375 emulsion pump is to provide a theoretical basis for further design, optimization and development of S375 emulsion pump.
