內(nèi)容提要
混凝土泵車作為我國工程機(jī)械的主力機(jī)種，被廣泛應(yīng)用于澆注混凝土施工作業(yè)中。泵車的核心技術(shù)就是液壓系統(tǒng)的設(shè)計(jì)，由于泵車的工作條件惡劣，要求實(shí)現(xiàn)的動(dòng)作較復(fù)雜，于是對液壓系統(tǒng)的設(shè)計(jì)提出了較高要求，其液壓系統(tǒng)也是工程機(jī)械液壓系統(tǒng)中較為復(fù)雜的。因此，對泵車液壓系統(tǒng)的分析設(shè)計(jì)對推動(dòng)我國泵車發(fā)展具有十分重要的意義。
本次設(shè)計(jì)的課題是SY5190THB 25混凝土輸送泵車液壓系統(tǒng)設(shè)計(jì)，內(nèi)容首先陳述了課題提出的背景，分析了泵車的發(fā)展趨勢及市場需求，再對泵車的基本構(gòu)造進(jìn)行確定。通過對泵車液壓系統(tǒng)總體分析設(shè)計(jì)了開式回路，制定了液壓系統(tǒng)工作原理圖和各回路液壓系統(tǒng)工作原理圖。最后完成對泵送機(jī)構(gòu)進(jìn)行設(shè)計(jì)與計(jì)算和配套件選型。
此設(shè)計(jì)在整體上結(jié)構(gòu)布局合理,液壓元件的選擇和使用具有較好的經(jīng)濟(jì)性和實(shí)用性,并且性能方面得到了最好的發(fā)揮。
Summary
Concrete pump as the main force of China's construction machinery models, are widely used in concrete pouring operations. The core technology is the hydraulic pump system design. As the truck's poor working conditions, requested action to achieve more complex, so the design of the hydraulic system put forward high requirements, its hydraulic system in the hydraulic system is more complex. Therefore, pump hydraulic system analysis and design of the pump to promote the development of China is of great significance.
This design issue is the design of the hydraulic system pump of SY5190THB 25,The contents of the first statement of the issues raised in the background, Analysis of the pump and market demand trends, Then the basic structure of the pump were determined. On-pump hydraulic system analysis and design of the overall open circuit, developing the work of the hydraulic system and the circuit schematic diagram of hydraulic system work. Finally completed the design and calculation of pump body and accessories selection.
The design on the whole reasonable structure, selection and use of hydraulic components has a better economy and practicality, and performance was the best play.
