【摘要】：高端液壓支架是煤礦綜采自動(dòng)化及我國(guó)煤礦綜采重大裝備的發(fā)展需求，，所謂高端主要表現(xiàn)為支護(hù)高度高、工作阻力大、可靠性好等特點(diǎn)。而安全閥是液壓支架的關(guān)鍵閥件，起控制和過(guò)載保護(hù)作用，其性能的好壞直接影響支架強(qiáng)度與安全系數(shù)，進(jìn)而影響采煤工作面的生產(chǎn)率和經(jīng)濟(jì)技術(shù)指標(biāo)。因此，開(kāi)展對(duì)高水基高壓大流量安全閥的研究不僅具有重要的科學(xué)意義，而且具有廣闊的應(yīng)用價(jià)值和巨大經(jīng)濟(jì)效益。 在查閱國(guó)內(nèi)外大量相關(guān)文獻(xiàn)基礎(chǔ)上，綜述了高壓大流量安全閥的研究現(xiàn)狀和應(yīng)用情況，結(jié)合國(guó)內(nèi)相關(guān)研究的進(jìn)展，確定了本文的主要研究方向。 本文以某一參數(shù)高端液壓支架用安全閥為對(duì)象，經(jīng)過(guò)理論分析計(jì)算，完成了特定參數(shù)下高壓大流量安全閥的結(jié)構(gòu)設(shè)計(jì)；采用PRO/E軟件繪制安全閥的流場(chǎng)的幾何模型，基于FLUENT仿真分析平臺(tái)建立高壓大流量安全閥流道流場(chǎng)的數(shù)學(xué)模型，對(duì)其進(jìn)行詳細(xì)的流場(chǎng)分析，明確了安全閥氣穴氣蝕的產(chǎn)生機(jī)理和影響因素，并提出高水基高壓大流量流道優(yōu)化方法；采用ANSYS軟件對(duì)高壓大流量安全閥進(jìn)行有限元分析，驗(yàn)證閥芯結(jié)構(gòu)強(qiáng)度；利用AMESim軟件分析了高壓大流量安全閥動(dòng)態(tài)特性。 最后，利用高壓大流量安全閥測(cè)試系統(tǒng)進(jìn)行了安全閥的啟溢閉特性試驗(yàn)，試驗(yàn)結(jié)果滿足設(shè)計(jì)要求，達(dá)到安標(biāo)標(biāo)準(zhǔn)，驗(yàn)證了理論分析和設(shè)計(jì)方法的正確性。
[Abstract]:High-end hydraulic support is the development demand of fully mechanized coal mining automation and major equipment in our country. The so-called high-end main features are high supporting height, high working resistance, good reliability and so on. The safety valve is the key valve of the hydraulic support, which plays the role of control and overload protection. Its performance directly affects the strength and safety factor of the support, and then affects the productivity and economic and technical index of the coal mining face. Therefore, the research of high water base high pressure and large flow safety valve is not only of great scientific significance, but also of wide application value and great economic benefit. On the basis of consulting a large number of related literatures at home and abroad, the research status and application of high pressure and large flow safety valve are summarized. The main research direction of this paper is determined in combination with the domestic related research progress. In this paper, the structure design of high pressure and large flow safety valve with certain parameters is completed by theoretical analysis and calculation, and the geometric model of the flow field of safety valve is drawn by PRO/E software. Based on the FLUENT simulation analysis platform, the mathematical model of the flow field of the high pressure and large flow relief valve channel is established, and the detailed flow field analysis is carried out, and the mechanism of cavitation and the influencing factors of the cavitation in the safety valve are clarified. The optimization method of high water base high pressure and large flow channel is put forward, the finite element analysis of high pressure and large flow safety valve is carried out by ANSYS software, and the strength of valve core structure is verified. The dynamic characteristics of high pressure and large flow safety valve are analyzed by AMESim software. Finally, the high pressure and large flow safety valve test system is used to test the opening and closing characteristics of the safety valve. The test results meet the design requirements and meet the safety standard. The correctness of the theoretical analysis and design method is verified.
