style="text-indent:25px">液壓系統(tǒng)的常見故障：空穴現(xiàn)象。現(xiàn)象：如果液壓系統(tǒng)中滲入空氣，液體中的氣泡隨著液流運動到壓力較高的區(qū)域時，氣泡在較高壓力作用下將迅速破裂，從而引起局部液壓沖擊，造成噪聲和振動。另外，由于氣泡破壞了液流的連續(xù)性，降低了油管的通油能力，造成流量和壓力的波動，使液壓元件承受沖擊載荷，影響其使用壽命。原因：液壓油中總含有一定量的空氣，通常可溶解于油中，也可以氣泡的形式混合于油中。當壓力低于空氣分離壓力時，溶解于油中的空氣分離出來，形成氣泡；當壓力降至油液的飽和蒸氣壓力以下時，油液會沸騰而產(chǎn)生大量氣泡。這些氣泡混雜于油液中形成不連續(xù)狀態(tài)，這種現(xiàn)象稱為空穴現(xiàn)象。部位：吸油口及吸油管中低于大氣壓處，易產(chǎn)生氣穴；油液流經(jīng)節(jié)流口等狹小縫隙處時，由于速度的增加，使壓力下降，也會產(chǎn)生氣穴。危害：氣泡隨油液運動到高壓區(qū)，在高壓作用下迅速破裂，廣州液壓系統(tǒng)購買，造成體積突然減小、周圍高壓油高速流過來補充，引起局部瞬間沖擊，廣州液壓系統(tǒng)購買，壓力和溫度急劇升高并產(chǎn)生強烈的噪聲和振動。措施：要正確設(shè)計液壓泵的結(jié)構(gòu)參數(shù)和泵的吸油管路，廣州液壓系統(tǒng)購買，盡量避免油道狹窄和急彎，防止產(chǎn)生低壓區(qū)；合理選用機件材料，增加機械強度、提高表面質(zhì)量、提高抗腐蝕能力。液壓試驗臺特點：所有泵閥與管路均采用316不銹鋼材質(zhì)。廣州液壓系統(tǒng)購買</p><div

style="text-indent:25px">液壓泵使用要注意液壓泵可以用支座或法蘭安裝，泵和原動機應(yīng)采用共同的基礎(chǔ)支座，法蘭和基礎(chǔ)都應(yīng)有足夠的剛性。特別注意:流量大于 (或等于)160L/min的柱塞泵，不宜安裝在油箱上。液壓泵和原動機輸出軸間應(yīng)采用彈性聯(lián)軸器連接，嚴禁在液壓泵軸上安裝帶輪或齒輪驅(qū)動液壓泵，若一定要用帶輪或齒輪與泵連接，則應(yīng)加一對支座來安裝帶輪或齒輪，該支座與泵軸的同軸度誤差應(yīng)不大于Φ0.05mm。吸油管要盡量短、直、大、厚，吸油管路一般需設(shè)置公稱流量不小于泵流量2倍的粗過濾器 (過濾精度一般為80～180μm)。液壓泵的泄油管應(yīng)直接接油箱，回油背壓應(yīng)不大于0.05MPa。油泵的吸油管口、回油管口均需在油箱較低油面200mm以下。特別注意在柱塞泵吸油管道上不允許安裝濾油器，吸油管道上的截止閥通徑應(yīng)比吸油管道通徑大一擋，吸油管道長L<2500mm，管道彎頭不多于兩個。廣州液壓系統(tǒng)購買液壓泵站自吸高度不得超過500mm，若采用補油泵供油，供油壓力不得超過0.5MPa。</p><div

style="text-indent:25px">液壓試驗臺的設(shè)備構(gòu)成：1、關(guān)鍵部件：通過液體增壓泵對液體進行增壓，以達到試驗壓力要求。2、氣動兩聯(lián)件：對壓縮空氣進行過濾及調(diào)壓；3、調(diào)速閥：調(diào)節(jié)驅(qū)動空氣流量，以調(diào)節(jié)增壓器的動作頻率，可延長增壓器的使用壽命；4、高壓過濾器：對氣體進行過濾處理；5、高壓限壓閥：設(shè)定增壓器的自動停機和開啟壓力，以保證增壓器能在設(shè)定壓力時自動停機。液壓試驗臺的輸出壓力可以無級調(diào)節(jié)，升壓速率可以自由設(shè)定；液壓試驗臺采用多泵供壓，輸出流量更大，試驗范圍更廣，可以滿足從1~690MPa 范圍內(nèi)的試壓要求。</p><p style="text-indent:25px">液壓站在使用過程中，引起人們注意的就是液壓油的使用，要結(jié)合實際情況正確選擇。液壓站的液壓油的粘度要控制好。過大則會加大摩擦的阻力，散熱性能就會變差，消耗的功率也會變多，長時間使用會導(dǎo)致整個設(shè)備發(fā)熱;過小則會發(fā)生滲漏的現(xiàn)象，從而降低工作壓力，影響工作效果。因此，在實際使用中，一定要根據(jù)液壓站的類型選用合適粘度的液壓油。液壓站是不能有空氣混入到液壓油中的。液壓油中一定不能混入空氣，否則會降低液壓站的工作效率，還會污染液壓站的一些零部件。因此，發(fā)現(xiàn)松閘的現(xiàn)象，一定要及時排除空氣。液壓試驗臺使用前檢查：操作相應(yīng)管路按鈕，觀察是否正常。</p><div

style="text-indent:25px">只要測得液壓系統(tǒng)回路中所需任意點處工作參數(shù)，將其與系統(tǒng)工作的正常值相比較，即可判斷出系統(tǒng)工作參數(shù)是否正常，是否發(fā)生了故障以及故障的所在部位。液壓系統(tǒng)中的工作參數(shù)，如壓力、流量、溫度等都是非電物理量，用通用儀器采用間接測量法測量時，首先需利用物理效應(yīng)將這些非電量轉(zhuǎn)換成電量，然后經(jīng)放大、轉(zhuǎn)換和顯示等處理，被測參數(shù)則可用轉(zhuǎn)換后的電信號表示并顯示。由此可判斷液壓系統(tǒng)是否有故障。參數(shù)測量方法:1.測壓力，首先將檢測回路的軟管接頭與雙球閥三通螺紋接口旋緊接通。打開球閥，關(guān)死溢流閥，切斷回油通道，這時從壓力表上可直接讀出所測點的壓力值（為系統(tǒng)的實際工作壓力）。2.測流量和溫度——慢慢松開溢流閥7手柄，再關(guān)閉球閥。重新調(diào)整溢流閥，使壓力讀數(shù)為所測壓力值，此時流量計讀數(shù)即為所測點的實際流量值。同時溫度計上可顯示出油液溫度值。3.測轉(zhuǎn)速（速度）——不論泵、馬達或缸其轉(zhuǎn)速或速度僅取決于兩個因素，即流量和它本身的幾何尺寸（排量或面積），所以只要測出馬達或缸的輸出流量（對泵為輸入流量），除以其排量或面積即得到轉(zhuǎn)速或速度值。液壓系統(tǒng)要合理選擇液壓油。全液壓升降機生產(chǎn)廠</p><p style="text-indent:25px">液壓泵站每隔三個月，要對油的品質(zhì)進行一下檢查。廣州液壓系統(tǒng)購買</p><p style="text-indent:25px">有計劃的維護：建立系統(tǒng)定期維護制度，對液壓系統(tǒng)較好的維護保養(yǎng)建議如下：1）至多500小時或是三個月就要檢查和更換油液。2）定期沖洗油泵的進口油濾。3）檢查液壓油被酸化或其他污染物污染情況，液壓油的氣味可以大致鑒別是否變質(zhì)。4）修護好系統(tǒng)中的泄漏。5）確保沒有外來顆粒從油箱的通氣蓋、油濾的塞座、回油管路的密封墊圈以及油箱其他開口處進入油箱。液壓系統(tǒng)泄漏的原因：（1）設(shè)計及制造的缺陷所造成的；（2）沖擊和振動造成管接頭松動；（3）動密封件及配合件相互磨損（液壓缸尤甚）；（4）油溫過高及橡膠密封與液壓油不相容而變質(zhì)。下面就結(jié)合以上幾個方面淺談一下控制泄漏的措施。廣州液壓系統(tǒng)購買</p><p
