机械毕业设计（论文）-HBT100混凝土泵液压系统设计(含全套CAD图纸).doc

摘要
近几年,随着建筑行业的飞速发展,泵送混凝土施工技术得到广泛的发展。一些小型、中型的混凝土泵,施工效率低,性价比高,而HBT100是一种大型的混凝土泵,它的泵送速度与小型、中型的相比有很多提高。本次设计课题是HBT100混凝土泵液压系统设计。以系统性,实用性,经济性,精简性为原则,设计混凝土泵液压系统原理、油箱和系统阀块,以及液压元件和辅助元件的选型。
主油泵吸油后,通过压力油口进入主溢流阀,通过冷却器和回油过滤器回到油箱。当主溢流阀关闭,压力油通过液动换向阀进入液压缸两个液压缸一前进一后退,当主油缸活塞运行到行程终点时,主油泵压力油通过另一液动换向阀进入分配缸,分配阀换向,分配阀换向终了,压力油通过液动换向阀进入主油缸,如此往复循环。采用泵送混凝土技术能改善混凝土的施工性能,具有提高抗渗性、改善耐久性特点。
关键词:混凝土泵、液压系统、分配阀、液压泵、液压缸。
Abstract
In recent years, with the rapid development of the construction industry, pumped concrete to get a wide range of development. Construction site, we can see many small and medium-sized concrete pump, HBT100 is a large concrete pump, pumping speed and small and medium-pared to a lot to improve. Design issues is HBT100 concrete pump hydraulic system design. The design of the main design of concrete pump hydraulic system, as well as the selection of concrete pump ponents and deal with some of mon hydraulic system failure. This design in a systematic, practical, economical, to streamline the principle of design concrete pump hydraulic system, fuel tank and system valve block. The pumping concrete technology can improve the workability of the concrete, to improve the impermeability to improve the durability characteristics. With this design, I have a deeper understanding of the hydraulic system of concrete pump
Key words: concrete pump, hydraulic system, distribution valve, hydraulic pump, hydraulic cylinder
