【摘要】：液壓傳動(dòng)具有功率質(zhì)量比大、可實(shí)現(xiàn)無級(jí)調(diào)速、操縱控制方便等優(yōu)點(diǎn)而被廣泛應(yīng)用于工業(yè)生產(chǎn)及日常生活領(lǐng)域。液壓傳動(dòng)工作介質(zhì)是液壓系統(tǒng)的重要組成部分,它將系統(tǒng)中的各類元件有機(jī)的連接起來構(gòu)成一個(gè)整體,實(shí)現(xiàn)信號(hào)和能量的傳遞,并具有防銹、冷卻、潤(rùn)滑等作用。液壓系統(tǒng)能否有效、可靠而且經(jīng)濟(jì)地工作,在很大程度上取決于液壓傳動(dòng)工作介質(zhì)的性能。液壓傳動(dòng)工作介質(zhì)不僅要有合適的粘度,良好的防銹性、抗乳化性、氧化穩(wěn)定性和相容性,更重要的是具有優(yōu)良的抗磨性能,以最大程度地減少液壓系統(tǒng)中元件摩擦副的磨損,延長(zhǎng)液壓元件及系統(tǒng)的使用壽命,提高液壓系統(tǒng)的能源利用率。隨著液壓系統(tǒng)工作壓力的不斷提高和新型液壓傳動(dòng)工作介質(zhì)的不斷應(yīng)用,傳統(tǒng)液壓油抗磨性試驗(yàn)臺(tái)已不能滿足液壓傳動(dòng)技術(shù)快速發(fā)展需要。 本論文在傳統(tǒng)液壓油抗磨性試驗(yàn)臺(tái)的基礎(chǔ)上,采用高壓液壓泵構(gòu)建高壓抗磨性試驗(yàn)系統(tǒng)并充分考慮新型液壓傳動(dòng)工作介質(zhì)的物理化學(xué)特性,分析其抗磨性產(chǎn)生的機(jī)理,重點(diǎn)對(duì)試驗(yàn)臺(tái)的液壓控制系統(tǒng)、數(shù)據(jù)采集系統(tǒng)和測(cè)試系統(tǒng)的界面進(jìn)行了分析和設(shè)計(jì)。 本論文首先介紹了液壓傳動(dòng)工作介質(zhì)的分類和常用抗磨性試驗(yàn)裝置及要求,針對(duì)傳統(tǒng)液壓油的抗磨性試驗(yàn)臺(tái),分析指出了其存在的問題。其次簡(jiǎn)述了試驗(yàn)泵的磨損系統(tǒng)及摩擦副的磨損形式,并針對(duì)不同種類的液壓傳動(dòng)工作介質(zhì)及其添加劑進(jìn)行抗磨性機(jī)理分析。然后根據(jù)液壓傳動(dòng)技術(shù)的最新發(fā)展對(duì)試驗(yàn)液壓泵、加載閥、傳感器、數(shù)據(jù)采集儀、工控機(jī)、開關(guān)電源等元件進(jìn)行選型,從而構(gòu)建試驗(yàn)臺(tái)的液壓控制系統(tǒng)和數(shù)據(jù)采集系統(tǒng)。最后采用圖形化編程軟件LabVIEW對(duì)測(cè)試系統(tǒng)進(jìn)行軟件設(shè)計(jì)。
[Abstract]:Hydraulic transmission is widely used in industrial production and daily life due to its advantages of high power mass ratio, stepless speed regulation and convenient operation and control. The working medium of hydraulic transmission is an important part of hydraulic system, which organically connects all kinds of components in the system to form a whole, realizes the transmission of signal and energy, and has the functions of rust prevention, cooling, lubrication and so on. Whether the hydraulic system can work effectively, reliably and economically depends to a great extent on the performance of the hydraulic transmission working medium. The working medium of hydraulic transmission should not only have proper viscosity, good anti-rust, anti-emulsification, oxidation stability and compatibility, but also have excellent anti-wear performance, so as to minimize the wear of friction pairs of components in hydraulic system. Prolong the service life of hydraulic components and systems and improve the energy efficiency of hydraulic systems. With the continuous improvement of the working pressure of hydraulic system and the continuous application of new hydraulic transmission working medium, the traditional hydraulic oil anti-wear test bench can not meet the rapid development of hydraulic transmission technology. On the basis of the traditional hydraulic oil antiwear test bench, the high pressure hydraulic pump is used to construct the high pressure antiwear test system, and the physical and chemical characteristics of the new hydraulic transmission working medium are fully considered, and the mechanism of its anti-wear property is analyzed. The interface of hydraulic control system, data acquisition system and test system is analyzed and designed. This paper first introduces the classification of working medium of hydraulic transmission, the commonly used anti-wear test equipment and its requirements, and points out the existing problems in view of the anti-wear test bench of traditional hydraulic oil. Secondly, the wear system of the test pump and the wear form of the friction pair are briefly introduced, and the anti-wear mechanism of different kinds of working media and additives of hydraulic transmission is analyzed. Then according to the latest development of hydraulic transmission technology, the hydraulic pump, loading valve, sensor, data acquisition instrument, industrial control computer, switching power supply and other components are selected to build the hydraulic control system and data acquisition system of the test bed. Finally, the software design of the test system is carried out by using the graphical programming software LabVIEW.
