【摘要】：蒸汽壓縮蒸餾裝置（VCD）是我國(guó)空間站工程尿液收集及再生處理系統(tǒng)中的關(guān)鍵設(shè)備，該裝置的密封對(duì)設(shè)備的性能具有至關(guān)重要的作用。傳統(tǒng)的密封無(wú)法滿足壽命長(zhǎng)、零泄漏、可靠性高等要求，基于磁性液體密封的優(yōu)點(diǎn)，擬采用磁性液體密封。 在了解磁性液體特性的基礎(chǔ)上，系統(tǒng)地整理總結(jié)了磁性液體密封理論、磁性液體密封結(jié)構(gòu)耐壓能力的計(jì)算公式及磁性液體密封結(jié)構(gòu)中永久磁鐵的計(jì)算公式。 依據(jù)磁性液體密封設(shè)計(jì)理論，設(shè)計(jì)了磁性液體密封結(jié)構(gòu)，其中包括極靴、永久磁鐵、導(dǎo)磁軸套、非導(dǎo)磁內(nèi)墊圈、非導(dǎo)磁外墊圈、隔磁套、非導(dǎo)磁壓環(huán)等零件，并且合理的選擇了合適的磁性液體。 運(yùn)用ANSYS軟件詳細(xì)地分析了磁性液體密封結(jié)構(gòu)，得到了磁力線分布圖、磁流密度矢量圖、磁流密度等值云圖、密封間隙處磁場(chǎng)強(qiáng)度分布曲線等，并計(jì)算了該密封結(jié)構(gòu)的耐壓能力，充分證明了磁性液體密封結(jié)構(gòu)設(shè)計(jì)的合理性。 使用ANSYS參數(shù)化設(shè)計(jì)語(yǔ)言開發(fā)了參數(shù)化分析模塊，完成了快捷鍵的設(shè)置，使軟件能夠自動(dòng)完成不同模型的分析及后處理。利用此模塊反復(fù)分析，得到了極齒高度、極齒寬度以及槽寬的取值范圍，，為密封結(jié)構(gòu)的優(yōu)化提供了依據(jù)。 建立了磁性液體密封結(jié)構(gòu)優(yōu)化數(shù)學(xué)模型，使用MATLAB軟件對(duì)磁性液體密封結(jié)構(gòu)進(jìn)行優(yōu)化，達(dá)到了減小磁性液體密封結(jié)構(gòu)重量的目標(biāo)。
[Abstract]:Steam Compression Distillation Unit (VCD) is a key equipment in the urine collection and regeneration system of space station engineering in China. The seal of VCD equipment plays an important role in the performance of the equipment. The traditional seal can not meet the requirements of long life, zero leakage and high reliability. Based on the advantages of magnetic liquid seal, magnetic liquid seal is proposed. On the basis of understanding the characteristics of magnetic fluid, the theory of magnetic liquid seal, the formula of pressure resistance of magnetic liquid seal structure and the formula of permanent magnet in magnetic liquid seal structure are systematically summarized. According to the theory of magnetic liquid seal design, the magnetic liquid seal structure is designed, which includes pole boot, permanent magnet, magnetic guide shaft sleeve, non-magnetic conduction inner gasket, non-magnetic conduction outer gasket, magnetic insulation sleeve, non-magnetic conductivity pressure ring and so on. And reasonable selection of the appropriate magnetic fluid. The magnetic fluid seal structure is analyzed in detail by using ANSYS software. The magnetic force line distribution diagram, the magnetic flow density vector diagram, the magnetic flow density equivalent cloud diagram, the magnetic field intensity distribution curve at the seal clearance are obtained, and the pressure resistance of the seal structure is calculated. The rationality of the structure design of magnetic liquid seal is fully proved. The parameterized analysis module is developed by using ANSYS parametric design language, and the shortcut key is set up, so that the software can automatically complete the analysis and post-processing of different models. By repeated analysis of this module, the value range of pole tooth height, pole tooth width and slot width is obtained, which provides the basis for the optimization of seal structure. The optimization mathematical model of magnetic liquid seal structure is established, and the structure of magnetic liquid seal is optimized by MATLAB software. The goal of reducing the weight of magnetic liquid seal structure is achieved.
