1、內(nèi)蒙古工業(yè)大學本科畢業(yè)設計說明書本科畢業(yè)設計說明書（題目：礦井支撐掩護式液壓支架液壓系統(tǒng)設計學生姓名：學院：機械學院系別：機械設計制造及其自動化系專業(yè)：機械設計制造及其自動化班級：指導教師：二〇〇九年六月1?摘要礦井液壓支架的應用對增加采煤工作面產(chǎn)量、提高勞動生產(chǎn)率、降低成本、減輕工人的體力勞動和保證安全生產(chǎn)是不可缺少的有效措施，因此液壓支架的設計是技術(shù)上先進、經(jīng)濟上合理，安全上可靠、是實現(xiàn)采煤綜合機械化和自動化的主要體現(xiàn)。采用綜合機械化采煤方法是大幅度增加煤炭產(chǎn)量、提高經(jīng)濟效益的必由之路。為了滿足對煤炭日益增長的需求，必須大量生產(chǎn)機械化采煤設備，迅速增加綜合機械化采
2、煤工作面。因此對液壓支架的需求也是日益增加，而液壓系統(tǒng)是驅(qū)動液壓支架工作的心臟，是液壓支架所不可缺少的重要組成。本次設計主要是針對礦井支撐掩護式液壓支架液壓系統(tǒng)的設計。包括了立柱千斤頂和推移千斤頂?shù)脑O計，泵站的設計及其整體的合理布局的設計。還涉及到對一些標準件的選用規(guī)則等。同時還對系統(tǒng)壓力損失、發(fā)熱、效率等性能進行了驗算。關(guān)鍵詞：液壓傳動；液壓系統(tǒng)；泵站；液壓支架Abstract?The?applicationofhydraulic?supportincoalmining?face?ofincreasing?productionand?raise?laborprodu
