【正文】 levels should adhere to the bottom line of thinking, fear discipline, hold the bottom line, as a preventive measure, to keep the party39。s purpose. 8 of these regulations, a total of three series, Chapter 15, 178, more than 24000 words, after the revision of the regulations a total of 3 series, Chapter 11, 133, 17000 words, divided into general and special provisions and Supplementary Provisions Part 3. Among them, add, delete, modify the provisions of the proportion of up to nearly 90%. 1, the general general is divided into five chapters. The first chapter to the regulations of the guiding ideology, principles and scope of application of the provisions, highlight the strengthening of the party constitution consciousness, maintenance the authority of Party Constitution, increase the party anizations and Party members must abide by the party constitution, Yan Centralized centralized, would examine at all levels of the amended provisions implementing and maintaining Party discipline, and consciously accept the party discipline, exemplary pliance with national laws and regulations. The second chapter of discipline concept, disciplinary action types and effects of the regulations, will be a serious warning from the original a year for a year and a half。 due to negligence crime and was sentenced to three years or more (excluding three years) a penalty, shall give expelled punishment. Due to negligence crime is convicted and sentenced to three years (including three years) in prison or be sentenced to public surveillance, detention, shall in general be expelled from the party. For the individual may not be expelled from the party, should control Approval. This is followed and retained the original Regulations the provisions of punishment party authorization rules and report to a level party anizations. For is party members with criminal acts, and by the criminal punishment, generally should be expelled from the party. The fifth chapter of probationary Party member of the discipline and discipline after missing members of the treatment and punishment decisions, such as the implementation of the provisions, clear the related party discipline and punishment decision made after, for duties, wages and other relevant alteration formalities for the longest time. 2, sub sub section will the original regulations of 10 categories of acts of violation of discipline integration revised into 6 categories, respectively, in violation of the punishments for acts of political discipline in violation of discipline behavior of punishment in violation of integrity of disciplina。s image, the damage to the party, the state and the people39。s leadership and the party39。s eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised low political criterion and Regulations , highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a longterm, advance as a whole, with Bu Xiuding independent rule and rule . Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and selfdiscipline required specific, awaken the party constitution of party passes party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2020 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules. the revision of the code and rule is Method in adhere to the regulations established for the purpose of bining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and selfdiscipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue de, mainly refers to the party39。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。 五、實驗成績評定 (考試方法 )： 1．實驗操作 10%，實驗報告 15%。此方法為了防止壓力繼電器發(fā)生誤動作，其壓力調(diào)整 數(shù)值一方面應(yīng)比先動的液壓缸的最高工作壓力高 ，另一方面要比溢流閥的調(diào)整壓力低 。 學會使用液壓元器件設(shè)計液壓動作回路，提高學生處理及解決問題的能力。 4）調(diào)節(jié)工作缸壓力控制系統(tǒng)的壓力（調(diào)節(jié)直動式溢流閥的調(diào)壓旋鈕），使工作缸活塞桿頂出壓力大于回程壓力。 2. 步驟 （ 1） 設(shè)計利用節(jié)流閥或調(diào)速閥的回油節(jié)流調(diào)速回路。 二、實驗設(shè)備和儀器 1．液壓系統(tǒng)試驗臺 2. 雙作用 液壓缸、 2 位 4 通手動換向閥、節(jié)流閥和調(diào)速閥 3. 油管若干 三、實驗內(nèi)容及要求 1. 請分別采用進油節(jié)流、回油節(jié)流兩種方法設(shè)計并組裝調(diào)試液壓回路，畫出回油液壓回路圖。 3） 打開調(diào)節(jié)液壓泵，開始液壓系統(tǒng)的運轉(zhuǎn)實驗 五、實驗結(jié)果分析及實驗報告要求 ： 實驗用液壓泵、缸、閥等元器件的名稱及性能？ 畫出兩位兩通卸荷回路實驗回路圖并說明實驗原理。 2) 學習回路的連接方法和過程。 6）變量機構(gòu)中的變量活塞裝在變量殼體 內(nèi)，并與螺桿相連。減小這些零件的磨損。 7）泵的出口壓力作用在活塞上，活塞對定子產(chǎn)生反饋力。 2）該泵共有 13 個葉片，流量脈動較偶數(shù)小。 2）觀察定于內(nèi)表面曲線的組成情況，分析其赤字波曲線的特點，分析其大圓弧半徑 R與小半徑 r 之差的大小與泵的流量有什么關(guān)系。 掌握液壓泵拆裝與維修方法，能正確拆裝液壓泵。 進一步熟練使用拆裝工具，了解一般拆裝方法。 2． YB型雙作用式定量葉片泵的拆裝 （ 1）葉片泵型號： YB 型葉片泵 （ 2）主要零件分析： 1）觀察 YB 泵的主要組成零件，弄清它們各起什么作用。定子徑向開有 13 條槽可以安置葉片。 6）調(diào)節(jié)螺釘可以改變活塞的原始位置，也改變了定子與轉(zhuǎn)子的原始偏心量，從而改變泵的最大流量。滑履隨柱塞和滑履中心開有直徑 1mm 的小孔，缸中的壓力油可進入柱塞和滑履、滑履和斜盤間的相對滑動表面，形成油膜，起靜壓支承作用。 5）滾動軸承用來承受斜盤 25 作用在缸體上的徑向力。 實驗二 兩位兩通卸荷回路 一、實驗?zāi)康? 1) 進一步認識和理解各種閥的工作原理、基本結(jié)構(gòu)，主要性能及其在液壓回路中的作用。 2） 接通電源，將二位兩通電磁換向閥接入電氣控制面板的插座中，啟動電氣控制面板上的開關(guān)。 學會設(shè)計二級壓力控制回路?；钊陆凳枪ぷ餍谐?，需要壓力較高，由溢流閥 A 調(diào)定泵的出口壓力值，活塞上升是非工作行程，所需較低壓力由溢流閥 B 調(diào)定，液壓缸的運動方向及壓力變換由二位四通電磁換
