③適當(dāng)布置壓力控制閥來保護(hù)系統(tǒng)的所有元件； ④盡量減少管接頭的使用數(shù)量，管接頭盡量用焊接連接； ⑤使用直螺紋接頭，三通接頭和彎頭代替錐管螺紋接頭； ⑥盡量用回油塊代替各個配管； ⑦針對使用的較高壓力，寶山泵站液壓系統(tǒng)，規(guī)定安裝時使用螺栓的扭矩和堵頭扭矩，寶山泵站液壓系統(tǒng)，寶山泵站液壓系統(tǒng)，防止結(jié)合面和密封件被蠶食； ⑧正確安裝管接頭。液壓系統(tǒng)中的油泵，它向整個液壓系統(tǒng)提供動力。寶山泵站液壓系統(tǒng)</p><div style="width:100%;text-align:

style="text-indent:25px">液壓系統(tǒng)優(yōu)點(diǎn)：1、體積小和重量輕；2、剛度大、精度高、響應(yīng)**、驅(qū)動力大，適合重載直接驅(qū)動；4、調(diào)速范圍寬，速度控制方式多樣；5、自潤滑、自冷卻和長壽命；6、易于實現(xiàn)安全保護(hù)。壓力損失：由于液體具有黏性，在管路中流動時又不可避免地存在著摩擦力，所以液體在流動過程中必然要損耗一部分能量。這部分能量損耗主要表現(xiàn)為壓力損失。壓力損失有沿程損失和局部損失兩種。沿程損失是當(dāng)液體在直徑不變的直管中流過一段距離時，因摩擦而產(chǎn)生的壓力損失。局部損失是由于管路截面形狀突然變化、液流方向改變或其他形式的液流阻力而引起的壓力損失?？偟膲毫p失等于沿程損失和局部損失之和。由于壓力損失的必然存在，所以泵的額定壓力要略大于系統(tǒng)工作時所需的較大工作壓力，一般可將系統(tǒng)工作所需的較大工作壓力乘以一個1.3~1.5的系數(shù)來估算。寶山泵站液壓系統(tǒng)液壓控制系統(tǒng)則要使液壓系統(tǒng)輸出滿足特定的性能要求，通常所說的液壓系統(tǒng)主要指液壓傳動系統(tǒng)。</p><div

style="text-indent:25px">液壓系統(tǒng)故障診斷中值得遵循：（1）首先判明液壓系統(tǒng)的工作條件和**環(huán)境是否正常需首先搞清是設(shè)備機(jī)械部分或電器控制部分故障，還是液壓系統(tǒng)本身的故障，同時查清液壓系統(tǒng)的各種條件是否符合正常運(yùn)行的要求。（2）區(qū)域判斷根據(jù)故障現(xiàn)象和特征確定與該故障有關(guān)的區(qū)域，逐步縮小發(fā)生故障的范圍，檢測此區(qū)域內(nèi)的元件情況，分析發(fā)生原因，較終找出故障的具體所在。（3）掌握故障種類進(jìn)行綜合分析根據(jù)故障較終的現(xiàn)象，逐步深入找出多種直接的或間接的可能原因，為避免盲目性，必須根據(jù)系統(tǒng)基本原理，進(jìn)行綜合分析、邏輯判斷，減少懷疑對象逐步逼近,較終找出故障部位。（4）驗證可能故障原因時，一般從較可能的故障原因或較易檢驗的地方開始，這樣可減少裝拆工作量，提高診斷速度。（5）故障診斷是建立在運(yùn)行記錄及某些系統(tǒng)參數(shù)基礎(chǔ)之上的。建立系統(tǒng)運(yùn)行記錄，這是預(yù)防、發(fā)現(xiàn)和處理故障的科學(xué)依據(jù)；建立設(shè)備運(yùn)行故障分析表，它是使用經(jīng)驗的高度概括總結(jié)，有助于對故障現(xiàn)象迅速做出判斷；具備一定檢測手段，可對故障做出準(zhǔn)確的定量分析。液壓油泵與控制閥間管道相連接，泵出的油流至閥，閥的任務(wù)是使油流向油缸或油箱。</p><div

style="text-indent:25px">日常查找液壓系統(tǒng)故障的傳統(tǒng)方法是邏輯分析逐步逼近斷?；舅悸肥蔷C合分析、條件判斷。即維修人員通過觀察、聽、觸摸和簡單的測試以及對液壓系統(tǒng)的理解，憑經(jīng)驗來判斷故障發(fā)生的原因。當(dāng)液壓系統(tǒng)出現(xiàn)故障時，故障根源有許多種可能。采用邏輯代數(shù)方法，將可能故障原因列表，然后根據(jù)先易后難原則逐一進(jìn)行邏輯判斷，逐項逼近，較終找出故障原因和引起故障的具體條件。一個液壓系統(tǒng)工作是否正常，關(guān)鍵取決于兩個主要工作參數(shù)即壓力和流量是否處于正常的工作狀態(tài)，以及系統(tǒng)溫度和執(zhí)行器速度等參數(shù)的正常與否。液壓系統(tǒng)的故障現(xiàn)象是各種各樣的，故障原因也是多種因素的綜合。同一因素可能造成不同的故障現(xiàn)象，而同一故障又可能對應(yīng)著多種不同原因。例如：油液的污染可能造成液壓系統(tǒng)壓力、流量或方向等各方面的故障，這給液壓系統(tǒng)故障診斷帶來極大困難。執(zhí)行元件(如液壓缸和液壓馬達(dá))的作用是將液體的壓力能轉(zhuǎn)換為機(jī)械能，驅(qū)動負(fù)載作直線往復(fù)運(yùn)動或回轉(zhuǎn)運(yùn)動。寶山泵站液壓系統(tǒng)</p><p style="text-indent:25px">生物降解液壓油是性能較強(qiáng)的抗磨損液壓油，專門為滿足各種液壓設(shè)備的要求而制。寶山泵站液壓系統(tǒng)</p><p style="text-indent:25px">液壓油保養(yǎng)工作（前提是設(shè)備正常運(yùn)行，無異常狀況）： 1、保證液壓油不在高溫下使用；油品在高溫下很快會氧化變質(zhì)。 2、液壓站上的空氣過濾器要采用既能過濾顆粒的也能過濾水分的過濾器。 3、采用精密濾芯過濾液壓油，使油品的污染度長期保持在NAS<8級，設(shè)備自帶的濾芯一般精度太差，不能保證液壓油的潔凈度。因為液壓站的容臟極限只有5um，而自帶濾芯的精度往往要大于這個尺寸，科學(xué)規(guī)定一般液壓站的污染度要求控制在NAS小于8級；對于有伺服機(jī)構(gòu)的設(shè)備要求更高，要小于7級。若你拆過伺服閥，那你就什么都明白了，為什么液壓油的污染度要控制得這么高。較好買個精密濾油機(jī)進(jìn)行在線過濾，有些濾芯精度已經(jīng)達(dá)到了0.1um。寶山泵站液壓系統(tǒng)</p><p
