【正文】 s Procuratorate shall make a decision not to initiate a prosecution, or the people39。 at the same time, to investigate violations of Party members and even criminal behavior of Party discipline and responsibility, Regulations distinguish five different conditions, with special provisions were made provisions, so as to realize the connection of Party discipline and state law. 4, reflect Wind building and anticorruption struggle of the latest achievements. rule the party39。s solemn mitment. criterion of a clean and honest administration consists of 4 parts, 18, more than 3600 words. After the revision of the code , a total of eight, 281 words, including lead, specification and Party member cadre clean fingered selfdiscipline norms, etc. Part 3 members lowcost clean and selfdiscipline, the main contents can be summarized as four must eight code. Lead part, reiterated on ideal and faith, fundamental purpose, the fine traditions and work style, noble sentiments, such as four must the principle of requirements, strong tone of selfdiscipline, The higher request for 6 and supervised te, the foothold in permanent Bao the party39。 the second is concisely positive advocated by the lack of prohibited provisions excessive, no autonomy requirements。 rule around the party discipline, disciplinary ruler requirements, listed as negative list, focusing on vertical gauge, draw the party anizations and Party members do not touch the bottom line . Here, the main from four square face two party rules of interpretation: the first part introduces two party Revised regulations the necessity and the revision process。如確定無誤，接通電源，啟動電氣控制面板的開關(guān)，把換向閥插座與電磁鐵換向閥進行連接，啟動液壓油泵開關(guān)，調(diào)節(jié)電機調(diào)速器使達到預定的壓力，按動換向閥 1 或 2 達到實驗預計的結(jié)果。 四、實驗內(nèi)容及要求 實驗內(nèi)容： （一）利用行程開關(guān)設計液壓的順序動作回路 （ 1） 實驗方法 采用電器行程開關(guān)的順序動作回路，各缸順序由電氣元件發(fā)出信號，改變油液的流動方向即可改變順序動作，并可調(diào)整行程。 實驗 用液壓泵、缸、閥等元器件的名稱及性能，并繪制設計的回油調(diào)速回路圖？ 簡述進油節(jié)流調(diào)速回路與回油節(jié)流調(diào)速回路的相同點和不同點，并分析為什么？ 思考并簡單回答下列問題 就低速平穩(wěn)性而言，回油節(jié)流調(diào)速優(yōu)于進油節(jié)流調(diào)速為什么？ 回油節(jié)流調(diào)速回路的缺點、優(yōu)點。 （ 4）通過觀察對照，理解進油節(jié)流調(diào)速回路的速度 負載特性曲線。根據(jù)流量連續(xù)性原理，調(diào)速閥安裝在液壓缸的回油路上也同樣可以調(diào)節(jié)與控制進入 液壓缸的流量。 實驗三 回油節(jié)流調(diào)速回路 （綜合設計） 一、實驗目的 學會使用節(jié)流閥、調(diào)速閥、溢流閥、二位四通電磁換向閥、液壓缸等液壓元器件來設計回油節(jié)流調(diào)速回路，加深對所學知識的理解與掌握。 二、實驗設備和儀器 1．液壓系統(tǒng)試驗臺 2. 液壓缸（單作用雙作用均可）、 2 位 4 通手柄操作換向閥、兩位兩通卸荷閥 3. 油管若干根 三、實驗內(nèi)容及要求 設計并連接如下圖（簡圖，具體參考教科書）所示的兩位兩通卸荷回路，了解各種元件作用及連接方法。轉(zhuǎn)動手輪，螺桿帶動變量活塞上下移動（因?qū)蜴I的作用，變量活塞不能轉(zhuǎn)動），通過銷軸使斜盤擺動，從而改變了斜盤傾角，達到變量目的。 4）配流盤上開有兩條月牙型配流窗口，外圈的環(huán)形槽是卸荷槽，與回油相通，使直徑超過卸荷槽的配流盤端面上的壓力降低到零，保證配流盤端面可靠地貼合。缸體右端面與配流盤相配合。這樣可以保證，壓油腔一側(cè)的葉片底部油槽和壓油腔相通，吸油腔一側(cè)的葉片底部油槽與吸油腔相通，保持葉片底部和頂部所受的液壓力平衡。 5）觀察配油盆的結(jié)構(gòu)，找出吸油區(qū)、壓油區(qū)、封油區(qū)；找出吸油區(qū)、壓油區(qū)、三角槽及環(huán)形糟，分析它們的配置原則。 三 、 實驗內(nèi)容及要求 1．齒輪泵拆裝分析 （ 1）齒輪泵型號： CB－ B 型齒輪泵 （ 2）主要零件分析： 1） 泵體的兩端面開有封油槽 d，此槽與吸油口相通，用來防止泵內(nèi)油液從泵體與泵蓋接合面外泄，泵體與齒頂圓的徑向間隙為 ～ 。 南昌工程學院 《液壓傳動與控制》 實驗指導書 機械設計制造及自動化專業(yè) 機械電子專業(yè) 車輛工程專業(yè) 文紅民 編 2020 年 7 月 目 錄 實驗一 液壓元器件結(jié)構(gòu)與功能 ................................................................... 4 實驗二 兩位兩通卸荷回路 ........................................................................... 9 實驗三 回油節(jié)流調(diào)速回路 ............................................................................ 11 實驗四 多缸順序控制回路 ............................................... 錯誤 !未定義書簽。 2）前后端蓋內(nèi)側(cè)開有卸荷槽 e 用來消除困油。 6）觀察泵用密封圈的位置及所用密封圈的形式。 4）滑塊用來支持定子，并承受壓力油對定子的作用力。缸體外表面鑲有鋼套并裝在滾動軸承上。兩個通孔（相當于葉片泵配流盤上的三角槽）起減少沖擊、降低噪音的作用。 四、實驗結(jié)果分析及實驗報告要求 ： 1. 在定量軸向柱塞油泵、單作用葉片泵（變量）、齒輪油泵和雙作用葉片泵中選一種，敘述其主要結(jié)構(gòu)及工作原理； ； 3. 拆裝中主要使用的工具； 4. 拆裝過程的感受。掌握整個回路的原理和作用。 培養(yǎng)使用各種液壓元器件進行系統(tǒng)回路的安裝、連接及調(diào)試等實踐能力。 ? 二級壓力控制回路，可以為機床或某些液壓傳動機械在工作過程的各個階段提供所需要的不同壓力。 （ 5） 進行實驗分析，并完成實驗報告。 七、實驗成績評定 (考試方法 )： 1．實驗操作 10%，實驗報告 15%。 本實驗動作過程如下：首先按動電鈕，電磁鐵 1DT 接通，左位接入，壓力油流入液壓缸 A 的左腔，右腔回油，實現(xiàn)動作，右行到終點時，缸 A 的擋鐵壓下行程開關(guān) 1XK，電磁鐵 2DT 通電，液壓供油又進入缸 B 實現(xiàn)動作 2。 （二）利用壓力繼電器的順序動作回路 檢查在實驗臺上搭建的液壓回路是否正確。 the second part is the interpretation of the two fundamental principles of the revision of laws and regulations in the party。 the third is banned terms and discipline law, both with the party discipline, disciplinary regulations repeat and Criminal law and other laws and regulations repeat。s advanced nature and purity, to reflect the revised standards requirements. Members of selfdiscipline norms around the party members how to correctly treat and deal with the public and private, cheap and rot thrifty and extravagance bitter music, put forward the four norms. Party leader cadre clean fingered selfdiscipline norms for the leadership of the party members and cadres of the vital few, around the clean politics, from civil servant of the color, the exercise of power, moral integrity, a good family tradition and other aspects of the leadership of the party members and cadres of the four norms norm norm. The Party member39。s eighteen years implement the spirit of the central provisions of the eight, against the requirements of the four winds and transformation for disciplinary provisions, reflecting the style construction is always on the road, not a gust of wind. In the fight against corruption out of new problems, increase the trading rights, the use of authority relatives profit and other disciplinary terms. Prominent discipline of the masses, the new against the interests of the masses and ignore the demands of the masses and other disciplinary terms and make provisions of the disposition and the destruction of the party39。s court shall make a conviction and exempted from criminal punishment shall be given within the party is removed from his post, probation or expelled from the party. Party members and crime, sheets were fined in accordance with For acts。s image of behavior, should be given expelled from the party. At this article is party member is in
