BRW200/31.5乳化液泵液力端设计 [摘要]乳化液泵是综合采煤工作面液压支架的主要动力提供，性能好坏对液压支架的可靠性有着重大影响。近几年来，随着综合采煤技术的不断提高，综合采煤的机械装备与技术能力都逐渐增高，煤矿对乳化液泵站可以提供的压力与流量要求更高。传统的设计费力、费时，甚至有个别时刻都无法实现研发高性能泵的目标。应用系统的仿真模拟技术是作为结构设计、优化的重要依据，为乳化液泵的设计、研究、优化提供了技术方面的支持。 这篇文章是结合了传统的设计思路和成体系的仿真技术，依据乳化液泵的有关资料，建立相对应的乳化液泵的数学模型:利用SolidWorks软件的三维建模，建立柱塞泵的完整三维模型，比较两种泵模型的数据资料，从而达到优化泵的对应参数、完善结构设计的目的。 [关键词]乳化液泵；容积效率；曲轴转速；SolidWorks仿真 Desig
