【摘要】：海水電液換向閥是液壓支架系統(tǒng)的一個重要組成部分，其性能的好壞直接影響到支架工作的穩(wěn)定。目前，國外發(fā)達國家在輪船支架開發(fā)中已取得了顯著的成效，其開發(fā)的支架自動化程度高、安全可靠、經(jīng)濟實用。因此，研究以海水為工作介質(zhì)的電液換向閥對我國海洋事業(yè)的發(fā)展具有劃時代的意義。 由于海水機理不同于油液，不能把油壓元件直接應(yīng)用到水液壓系統(tǒng)中。本文分析了國內(nèi)外海水電液換向閥研究現(xiàn)狀，吸收國外先進海水電液換向閥的成熟技術(shù)，提出了符合我國國情的海上專用海水電液換向閥的研究方案。通過分析海上工作環(huán)境以及海水機理的特殊性，，選用新型材料和密封形式在一定程度上解決工作介質(zhì)帶來的泄漏和磨損問題，為換向閥的研制提供了前提條件；對比分析各類閥芯結(jié)構(gòu)形式，確定了以球閥式先導(dǎo)、錐閥式為主閥的閥芯結(jié)構(gòu)可行性。在此基礎(chǔ)上對先導(dǎo)閥和主閥運動過程進行研究，建立先導(dǎo)閥、主閥開啟和關(guān)閉的動態(tài)數(shù)學(xué)模型，利用Matlab\Simulink仿真軟件對數(shù)學(xué)模型進行仿真分析，其結(jié)果表明該方案的合理性。根據(jù)先導(dǎo)閥的工況，對海水電液換向閥所用的電磁鐵結(jié)構(gòu)進行ANSYS二維靜態(tài)建模仿真，分析電磁鐵外軛、銜鐵、底座、線圈之間的結(jié)構(gòu)參數(shù)對電磁吸力的影響。分析結(jié)果為節(jié)約材料、縮小尺寸、減少功耗提供了理論依據(jù)，為最終實現(xiàn)海水電液換向閥向小型化方向發(fā)展奠定了基礎(chǔ)。
[Abstract]:Marine electro-hydraulic directional valve is an important part of hydraulic support system, and its performance directly affects the stability of the support. At present, the developed countries have achieved remarkable results in the development of ship support, which has high degree of automation, safety and reliability, economic and practical. Therefore, the study of electro-hydraulic directional valve with seawater as working medium is of epoch-making significance to the development of marine industry in China. Because the mechanism of seawater is different from that of oil, oil pressure elements can not be directly applied to water hydraulic system. This paper analyzes the present research situation of sea water electro-hydraulic directional valve at home and abroad, absorbs the mature technology of foreign advanced sea water electro-hydraulic directional valve, and puts forward the research scheme of sea water electro-hydraulic directional valve suitable for the national conditions of our country. By analyzing the particularity of marine working environment and seawater mechanism, selecting new materials and sealing forms to solve the leakage and wear problems caused by working medium to a certain extent, which provides a prerequisite for the development of directional valve. By comparing and analyzing all kinds of valve core structure, the feasibility of valve core structure with ball valve pilot and cone valve as main valve is determined. On this basis, the motion process of pilot valve and main valve is studied, and the dynamic mathematical model of pilot valve and main valve opening and closing is established. The simulation analysis of the mathematical model is carried out by using Matlab\ Simulink simulation software. The results show that the scheme is reasonable. According to the working condition of the pilot valve, the electromagnet structure used in the seawater electro-hydraulic directional valve is modeled and simulated by ANSYS, and the influence of the structure parameters between the yoke, armature, base and coil of the electromagnet on the electromagnetic suction is analyzed. The results provide a theoretical basis for material saving, size reduction and power consumption reduction, and lay a foundation for the ultimate development of seawater electro-hydraulic directional valve towards miniaturization.
