【正文】 members in existing main problems of selfdiscipline, put forward principles, requirements and specifications, showing Communists noble moral pursuit, reflected at all times and in all over the world ethics from high from low 5 mon requirements. One is closely linked to the selfdiscipline, removal and no direct relation to the provisions of . the second is adhere to a positive advocate, eight prohibition 52 are not allowed to about the content of the negative list moved into synchronization amendment cases . Three is for all the party members, will apply object from the leadership of the party members and cadres to expand to all Party members, fully embodies the prehensive strictly required. The fourth is prominent key minority, seize the leadership of the party members and cadres is the key, and put forward higher requirements than the ordinary Party members. Five is to simplify, and strive to achieve concise, easy to understand, easy to remember. The revised code is the ruling Party since the first insists on a positive advocate forAll Party members and the selfdiscipline norms, moral declaration issued to all members of the party and the National People39。s eighteen years prehensive strictly practice. (a) revised two regulations of the party need of the ICAC guidelines in in 1997 Leaders as members of the Communist Party of China clean politics certain criteria (Trial) based on revised, the promulgation and implementation of January 2020, to strengthen the construction of the contingent of leading cadres play an important role. But with the party to manage the party strictly administering the deepening, has not been able to fully meet the actual needs. Content is too plicated, eight prohibition, 52 are not allowed to hard to remember, and also difficult to put into practice。（英文版 ） Two regulations promulgated for implementation is in the party in power for a long time and the rule of law conditions, the implementation of prehensive strictly strategic plan, implementation in accordance with the rules and discipline to manage the party, strengthen innerparty supervision of major initiatives. The two regulations supporting each other, the code adhere to a positive advocate, focusing on morality is of Party members and Party leading cadres can see, enough to get a high standard。 /卸載控制：當用氣量發(fā)生變化小于 98%時，壓縮機自動進入卸載狀況，在此狀態(tài)下超過設定 6 分鐘，控制系統(tǒng)指令停機，以免不必要的電能消耗，當用氣量增大時，則自動啟動轉入負載狀態(tài)。 2．箱體內附有吸音材料，更配有消音整流罩，通過這些全面有效的降噪措施，使其噪聲與同類型空壓機相比更為降低，特別是使用 200300小時后，更為明顯。因此，蝸桿不受任何徑向或軸向氣體力的作用 ,且星輪片上所受的力也只是雙螺桿壓縮機的 1/30左右，故蝸桿壓縮機的主機能平衡，無振動地在高轉速下運轉，而無需特別的基礎，僅需安放在水平地面上。因此，雙螺桿壓縮機與蝸桿壓縮機相比，在相同轉速下單位內排氣次數少，氣流脈動大，氣流噪聲大。蝸桿式轉速為每分鐘 2970轉（ 2970r/min）， 12個氣缸，則每分鐘排氣次數為35640次。螺桿壓縮機的主機殼體上均開有噴油孔，憑藉自身的壓力差，在壓縮過程中將油噴到壓縮腔，以冷卻氣體，密封各部件間隙，并起到吸振、消聲及潤滑的作用。上海浪潮機器有限研制的 OG30A 蝸桿壓縮機 1995 年通過中國通用機械研究所鑒定，在一系列的關鍵技術上填補了國內空白，在國內大幅度領先，部分參數達到國際先進水平。潛水艇對壓縮機的各項性能均有嚴格的要求，然而美國海軍為了淘汰活塞式壓縮機，對現有的各種壓縮機進行了大量的試驗與論證認為；蝸桿壓縮機是潛水艇采用的最佳壓縮機，對于高壓無油壓縮機來說是唯一的選擇。蝸桿受力平衡使蝸桿壓縮機具有一系列優(yōu)點：（ 1）運轉平穩(wěn)、振動小、噪聲比雙螺桿低 10%以上；（ 2）蝸桿沒有彎曲變形，可以在高壓下，例如：美國德萊賽目前西方發(fā)達國家螺桿壓縮機市場占有率為 80%，并保持上升勢頭。單螺桿壓縮機的發(fā)明比雙螺桿壓縮機晚十幾年，設計上更趨合理、先進。而噴油蝸桿壓縮機減少因粘性而引起的剪切損失而不能采用小間隙，目前單、雙螺桿壓縮機在噴油機方面的能耗指數相當。主要用作空氣壓縮機、冷凍（空調）機、熱泵和在化工生產的工藝流程中壓縮各種氣體或輸送天然氣、煤氣等。以下大致介紹一下蝸桿式壓縮機的技術概況： 1．結構形式雙螺桿壓縮機是一種雙軸容積式回轉型壓縮機，其主要是主（陽）副（陰）兩根轉子配合，組成嚙合副，主副轉子齒形外部同機殼內壁構成封閉的基元容積；而蝸桿壓縮機是一種單軸容積式回轉型壓縮機，其嚙合副是由一根蝸桿和兩個對稱平面布置的星輪所組成，由其蝸桿螺槽和星輪齒面及機殼內壁形成封閉的基元容積。 曲 軸連桿往復運動結構，由于其往復運動的特性，限制了其轉速的提高，致使機器笨重，同時，該運動結構所產生的慣性力能以平衡，剩余的慣性力，會使機器產生振動、噪聲以及零部件的不正常的損壞。二）蝸桿壓縮機與雙螺桿壓縮機的比較：由技術概況可知，蝸桿壓縮機除具備雙螺桿回轉式壓縮機結構簡單、緊湊、單位容積利用率高和無氣閥組件等特點外，因其星輪對稱地配置于蝸桿的兩側，還具有下列雙螺桿壓縮機所無法比擬的獨特優(yōu)點。 結構合理，具有理想的力平衡性 雙螺桿壓縮機主機的主要件就是兩個螺桿（俗稱雙螺桿），蝸桿壓縮機的主要件是蝸桿（俗稱單螺桿）。 維護簡便，易損件少 世界上沒有永不磨損的機器，無論雙螺桿壓縮機還是蝸桿壓縮機，在若干年后，均需對主機進行維修保養(yǎng)。 5．堅固的帶有起重槽口的鋼結構底座，有力地支承著整體，不需再另外加固地基或象雙螺桿空壓機那樣有避震設施，就能保證平穩(wěn)無震動運行。 C．高溫控制器，當油所氣溫度過高時可使壓縮機停機。 the third part introduces two party regulations modified the main changes and needs to grasp several key problems。 the fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of countylevel leading cadres above. rule is in 1997 Chinese Communist Party disciplinary cases (Trial) based on revision, in December 2020 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the prehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repetition。s selfdiscipline norms and party members and leading cadre clean fingered selfdiscipline norms, a total of eight, collectively referred to as the eight. Four must and eight of the content from the party constitution and Party39。s close ties with the masses. Discipline to protect the party39。 the principal Ordinance amended the provisions of the preceding paragraph. This is the new content, in order to achieve Ji method effective convergence. Five is the thirty third article 10 of the provisions, the Party member due to an intentional crime is sentenced to criminal law (including probation) sheets or additional deprivation of political rights。s interests, we should depend on the situation Seriousness given disciplinary action. The loss of Party members, seriously damaging the party39。s basic theory, basic line, basic program and basic experience, the basic requirement of behavior made prescribed punishment, increase the cliques, against the anization such as violation of the provisions, to ensure that the central government decrees and the Party of centralized and unified. 3, adhere to strict discipline in the law and discip
