【摘要】:液壓傳動(dòng)技術(shù)是現(xiàn)代工業(yè)廣泛應(yīng)用技術(shù)之一。它以其很高的輸出功率-質(zhì)量比和大范圍無(wú)級(jí)調(diào)速等優(yōu)點(diǎn)成為諸如工程機(jī)械等重型設(shè)備領(lǐng)域首選的傳動(dòng)技術(shù)。水液壓傳動(dòng)技術(shù)具有綠色、無(wú)污染等優(yōu)勢(shì),是液壓傳動(dòng)技術(shù)的重要發(fā)展方向。水液壓泵作為水液壓傳動(dòng)技術(shù)的核心元件,其性能優(yōu)劣將直接對(duì)水液壓傳動(dòng)系統(tǒng)的整體性能和壽命產(chǎn)生重大影響。然而,由于水介質(zhì)固有特性的影響,水液壓傳動(dòng)元件的研制都面臨著諸如腐蝕、潤(rùn)滑、摩擦磨損、抗氣蝕等重大基礎(chǔ)問(wèn)題。因此,開(kāi)展水液壓泵金屬材料及其工藝的基礎(chǔ)試驗(yàn)研究,不僅對(duì)研制水液壓泵具有實(shí)際意義,也對(duì)于其他類(lèi)型的水液壓元件的研制具有重要的參考意義。 本論文基于前一代試驗(yàn)樣機(jī)中出現(xiàn)的關(guān)鍵元部件抗蝕差等問(wèn)題,對(duì)于一些篩選后的金屬材料及工藝配對(duì)進(jìn)行了抗蝕性能的研究,并根據(jù)研究結(jié)果分析試制了新一代的試驗(yàn)樣機(jī)。根據(jù)最后的試驗(yàn)結(jié)果表明:新的樣機(jī)在抗蝕性能上得到了較大的提高,相對(duì)于前一代樣機(jī)有了明顯的改觀。論文主要內(nèi)容如下: 第一章,概述了水液壓技術(shù)背景以及國(guó)內(nèi)外水液壓元件材料抗蝕性能方面和樣機(jī)研制方面的現(xiàn)狀及相關(guān)產(chǎn)品,結(jié)合實(shí)際提出了本課題研究的重要意義。 第二章,分析了水液壓泵不同零部件對(duì)金屬材料的不同要求,確立了金屬材料抗蝕試驗(yàn)的總體方案,并初步選定了一些金屬材料和工藝配對(duì)作為考察對(duì)象。 第三章,介紹了所選定金屬材料的鹽霧試驗(yàn),按照相關(guān)標(biāo)準(zhǔn)規(guī)范設(shè)計(jì)并完成了鹽霧試驗(yàn),試驗(yàn)中定時(shí)觀察并做好記錄,試驗(yàn)后對(duì)試件進(jìn)行了清洗、稱重、留影和宏觀分析。 第四章,討論了鹽霧試驗(yàn)后各組配對(duì)的微觀表現(xiàn),利用電子顯微鏡及能譜儀等儀器對(duì)試驗(yàn)后的各組配對(duì)進(jìn)行了分析研究,總結(jié)出了一定的共性問(wèn)題。 第五章,介紹了水液壓泵實(shí)體樣機(jī)的試制方案、考核試驗(yàn)及試驗(yàn)后狀況分析,各項(xiàng)考核試驗(yàn)后,經(jīng)拆機(jī)檢查之后,樣機(jī)總體性能表現(xiàn)良好,各零件表現(xiàn)出了良好的抗蝕能力。 第六章,總結(jié)概述全文內(nèi)容,對(duì)于課題方向提出展望。
[Abstract]:Hydraulic transmission technology is one of the widely used technologies in modern industry. It has become the preferred transmission technology in the field of heavy equipment such as construction machinery because of its high output power-mass ratio and wide range stepless speed regulation. Water hydraulic transmission technology has the advantages of green and no pollution, so it is an important development direction of hydraulic transmission technology. Water hydraulic pump as the core component of water hydraulic transmission technology, its performance will directly affect the overall performance and life of water hydraulic transmission system. However, due to the influence of the inherent characteristics of water medium, the development of water hydraulic transmission elements is faced with such important basic problems as corrosion, lubrication, friction and wear, cavitation resistance and so on. Therefore, it is of great significance not only for the development of water hydraulic pump, but also for the development of other types of water hydraulic components to carry out the basic experimental research on metal materials and its technology of water hydraulic pump. In this paper, the corrosion resistance of some selected metal materials and process pairs has been studied based on the anti-corrosion difference of key components in the previous generation of test prototype, and a new generation of test prototype has been developed based on the analysis of the research results. The experimental results show that the corrosion resistance of the new prototype is greatly improved compared with the previous prototype. The main contents of the thesis are as follows: In the first chapter, the background of water hydraulic technology, the current situation of corrosion resistance of water hydraulic components at home and abroad and the development of prototype and related products are summarized, and the significance of this research is put forward in combination with the practice. In the second chapter, the different requirements of different parts of water hydraulic pump for metal materials are analyzed, the overall scheme of corrosion resistance test of metal materials is established, and some metal materials and process pairs are preliminarily selected as the object of investigation. In the third chapter, the salt spray test of the selected metal material is introduced. The salt spray test is designed and completed according to the relevant standards and specifications. The test is observed and recorded at regular time. After the test, the specimen is cleaned, weighed, photographed and macroscopically analyzed. In chapter 4, the microcosmic behavior of each group pairing after salt spray test is discussed, and some common problems are summarized by means of electron microscope and energy spectrometer. In the fifth chapter, the paper introduces the trial production scheme of the solid prototype of the water hydraulic pump, the examination test and the analysis of the condition after the test. After each examination test, the overall performance of the prototype is good after the disassembly machine is checked, and the parts show good corrosion resistance. The sixth chapter summarizes the content of the full text and puts forward the prospects for the direction of the subject.
