本文在分析引进设备的基础上，利用往复泵和液压系统等设计思想，对大粘度提取泵进行了理论论证和结构参数设计，该泵不但结构独特而且性能得到改善和提高，并在生产实践验证中，达到了令人十分满意的效果。
Based on the analysis of the imported equipment, this paper makes use of the design idea of reciprocating pump and hydraulic system to carry out the theoretical argumentation and structure parameter design of the large viscosity extraction pump. The pump not only has the unique structure but also improves and improves the performance. In, reached a very satisfactory result.
