【摘要】：氣動(dòng)技術(shù)是實(shí)現(xiàn)自動(dòng)化和機(jī)械化的有效手段之一,具有高速高效、潔凈安全、低成本及易維護(hù)等優(yōu)點(diǎn),其在工業(yè)領(lǐng)域中的應(yīng)用正日益廣泛。不難預(yù)料,隨著科技的發(fā)展,氣動(dòng)技術(shù)將得到更大的發(fā)展空間,并將在工業(yè)自動(dòng)化方面得到更廣泛的應(yīng)用。 本文首先介紹了氣壓電磁閥的發(fā)展概況以及可靠性技術(shù)研究現(xiàn)狀。接著詳細(xì)介紹了氣壓電磁閥的一般設(shè)計(jì)方法,分別從磁隙分析、結(jié)構(gòu)形式以及電磁系統(tǒng)設(shè)計(jì)等方面加以闡述。在介紹了可靠性設(shè)計(jì)概論后,結(jié)合自己從事的科研工作,對(duì)三通氣壓電磁閥的可靠性性能做了深入分析。在缺乏廣泛理論研究的基礎(chǔ)上,結(jié)合產(chǎn)品的實(shí)際使用情況及試驗(yàn)調(diào)試過(guò)程中出現(xiàn)的故障,作者總結(jié)并給出了三通氣壓電磁閥故障樹(shù)模型。在改進(jìn)設(shè)計(jì)中,注重失效模式與產(chǎn)品性能的關(guān)聯(lián)影響,綜合分析產(chǎn)品的各項(xiàng)性能指標(biāo),提出了三通氣壓電磁閥的可靠性設(shè)計(jì)方法,克服了以往設(shè)計(jì)中存在的此消彼長(zhǎng)的弊端。不僅如此,在注重改進(jìn)設(shè)計(jì)的同時(shí),加強(qiáng)了對(duì)產(chǎn)品研制工藝環(huán)節(jié)的可靠性工作研究,通過(guò)對(duì)設(shè)計(jì)環(huán)節(jié)和加工制造環(huán)節(jié)的全過(guò)程可靠性工作,產(chǎn)品的可靠性得到了較大提高。改進(jìn)設(shè)計(jì)后的產(chǎn)品,經(jīng)試驗(yàn)驗(yàn)證,綜合性能指標(biāo)有了較大幅度地提高,可靠性也有了顯著增長(zhǎng),特別是其工作壽命得到了翻倍的提高。盡管研究工作有一定的局限性,但對(duì)類(lèi)似氣壓電磁閥的研制設(shè)計(jì)仍有一定的借鑒意義。
[Abstract]:Pneumatic technology is one of the effective means to realize automation and mechanization. It has the advantages of high speed, high efficiency, clean and safe, low cost and easy maintenance. It is not difficult to predict that with the development of science and technology, pneumatic technology will get more development space, and will be more widely used in industrial automation. This paper first introduces the development of pneumatic solenoid valve and the research status of reliability technology. Then the general design method of pneumatic solenoid valve is introduced in detail, including magnetic gap analysis, structure form and electromagnetic system design. After introducing the introduction of reliability design, the reliability performance of three-way pneumatic solenoid valve is deeply analyzed in combination with its own scientific research work. On the basis of the lack of extensive theoretical research, combined with the actual use of the product and the faults in the process of test and debugging, the fault tree model of the three-way pneumatic solenoid valve is summarized and given. In the process of improving design, the relationship between failure mode and product performance is paid attention to, and the reliability design method of three-way pneumatic solenoid valve is put forward by synthetically analyzing the various performance indexes of the product, which overcomes the drawback that existed in the previous design. Not only that, but also the research on the reliability of the process of product development has been strengthened, and the reliability of the product has been greatly improved through the reliability work of the whole process of the design link and the manufacturing link. The experimental results show that the comprehensive performance index has been greatly improved, and the reliability has increased significantly, especially its working life has been doubled. Although the research work has some limitations, it still has some reference significance for the development and design of similar pneumatic solenoid valve.
