style="text-indent:25px">由液壓系統(tǒng)的工作原理可知，在系統(tǒng)中產(chǎn)生熱量的有兩部份：一個(gè)是將機(jī)械能轉(zhuǎn)化為壓力能的動力元件油泵，另一個(gè)是將壓力能轉(zhuǎn)化為機(jī)械能的控制元件和執(zhí)行元件；這兩部份在正常工作狀態(tài)下都要產(chǎn)生熱量，這些熱量由系統(tǒng)的冷卻系統(tǒng)進(jìn)行冷卻。一般流量較大的液壓系統(tǒng)均裝有冷卻系統(tǒng)，大部分會采用水冷卻。它的基本原理是用溫度較低的水與高溫液壓油進(jìn)行熱交換，來不斷帶走液壓系統(tǒng)中產(chǎn)生的熱量，使液壓系統(tǒng)的溫度保持在一個(gè)相對恒定的范圍內(nèi)。冷卻水不通或入口水溫比系統(tǒng)油溫高達(dá)不到與液壓油形成熱交換的作用。冷卻器(熱交換器)內(nèi)部結(jié)垢，導(dǎo)致冷卻效率降低，使液壓油油溫不能維持在正常水平。保持油液清潔是液壓系統(tǒng)可靠工作的關(guān)鍵，而過濾器則是保持油液清潔的主要手段。</p><div

style="text-indent:25px">從動力源泵的方面來考慮，考慮到執(zhí)行器工作狀況的多樣化，有時(shí)系統(tǒng)需要大流量，低壓力；有時(shí)又需要小流量，高壓力。所以選擇限壓式變量泵為宜，因?yàn)檫@種類型的泵的流量隨系統(tǒng)壓力的變化而變化。當(dāng)系統(tǒng)壓力降低時(shí)，流量比較大，能滿足執(zhí)行器的快速行程。當(dāng)系統(tǒng)壓力提高時(shí)流量又相應(yīng)減小，能滿足執(zhí)行器的工作行程。這樣既能滿足執(zhí)行器的工作要求，又能使功率的消耗比較合理。液壓油流經(jīng)各類液壓閥時(shí)不可避免的存在著壓力損失和流量損失，這一部分的能量損失在全部能量損失中占有較大的比重。因此，合理選擇液壓器，調(diào)整壓力閥的壓力也是降低功率損失的一個(gè)重要方面。流量閥按系統(tǒng)中流量調(diào)節(jié)范圍選取并保證其較小穩(wěn)定流量能滿足使用要求，壓力閥的壓力在滿足液壓設(shè)備正常工作的情況下，盡量取較低的壓力。建議定期更換液壓油和過濾器。松江區(qū)液壓系統(tǒng)多少錢</p><p

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。基本思路是綜合分析、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(yàn)來判斷故障發(fā)生的原因。當(dāng)液壓系統(tǒng)出現(xiàn)故障時(shí)，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(xiàng)逼近，找出故障原因和引起故障的具體條件。故障診斷過程中要求維修人員具有液壓系統(tǒng)基礎(chǔ)知識和較強(qiáng)的分析能力，方可保證診斷的效率和準(zhǔn)確性。但診斷過程較繁瑣，須經(jīng)過大量的檢查，驗(yàn)證工作，而且只能是定性地分析，診斷的故障原因不夠準(zhǔn)確。為減少系統(tǒng)故障檢測的盲目性和經(jīng)驗(yàn)性以及拆裝工作量，傳統(tǒng)的故障診斷方法已遠(yuǎn)不能滿足現(xiàn)代液壓系統(tǒng)的要求。隨著液壓系統(tǒng)向大型化、連續(xù)生產(chǎn)、自動控制方向發(fā)展，又出現(xiàn)了多種現(xiàn)代故障診斷方法。如鐵譜技斷，可從油液中分離出來的各種磨粒的數(shù)量、形狀、尺寸、成分以及分布規(guī)律等情況，及時(shí)、準(zhǔn)確地判斷出系統(tǒng)中元件的磨損部位、形式、程度等。而且可對液壓油進(jìn)行定量的污染分析和評價(jià)，做到在線檢測和故障預(yù)防。徐州液壓系統(tǒng)廠家</p></p><br
