style="text-indent:25px">液壓油用途普遍，是工業(yè)用油中使用較多的產(chǎn)品。當前液壓元件正向著體積小、功率大方向發(fā)展，系統(tǒng)壓力越來越高，有的已突破50MPa。為此，普通型的L-HL系列已經(jīng)趨于淘汰，抗磨型L-HM系列應(yīng)用更多。低溫性能也是液壓油的重要特性，要求在低溫環(huán)境下設(shè)備啟動比較容易，且動力傳動靈敏，而且液壓油換油周期較長，如露天設(shè)備通常一年一換，液壓油在使用過程中不可避免地要經(jīng)歷四季的變化，因此露天設(shè)備使用低凝產(chǎn)品效果較好。清潔度也已成為液壓油的性能要求，一般產(chǎn)品要NAS顆粒度等級不大于9級，清潔型產(chǎn)品不大于7級，高清潔型產(chǎn)品不大于5級，但盲目追求NAS等級不但沒有任何效果，反而降低質(zhì)量，增加成本。例如有些機械生產(chǎn)廠家，或工程機械用戶沒有用于添加液壓油的無塵車間，即使花了大價錢購買了NAS 5級別的產(chǎn)品，在打開產(chǎn)品的瞬間，高清潔型NAS 5液壓油就變成了NAS 8的等級了，而且液壓油NAS等級高意味著過濾次數(shù)多，過濾過程中就會把昂貴的添加劑成分過濾掉，因此從專業(yè)的角度來講，NAS等級不必過于追求。淄博柴油機液壓系統(tǒng)規(guī)格液壓油中總含有一定量的空氣，通?？扇芙庥谟椭?，也可以氣泡的形式混合于油中。</p><div

style="text-indent:25px">液壓沖擊：原因：執(zhí)行元件換向及閥門關(guān)閉使流動的液體因慣性和某些液壓元件反應(yīng)動作不夠靈敏而產(chǎn)生瞬時壓力峰值，稱液壓沖擊。其峰值可超過工作壓力的幾倍。危害：引起振動，產(chǎn)生噪聲；使繼電器、順序閥等壓力元件產(chǎn)生錯誤動作，甚至造成某些元件、密封裝置和管路損壞。措施：找出沖擊原因避免液流速度的急劇變化。延緩速度變化的時間，估算出壓力峰值，采用相應(yīng)措施。如將流動換向閥和電磁換向閥聯(lián)用，可有效地防止液壓沖擊。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。</p><p style="text-indent:25px">元件堵塞與卡緊故障：固體顆粒堵塞液壓閥的間隙和孔口，引起閥芯阻塞和卡緊，影響工作性能，甚至導(dǎo)致嚴重的事故。加速油液性能的劣化：油液中的水和空氣以其熱能是油液氧化的主要條件，而油液中的金屬微粒對油液的氧化起重要催化作用，此外，油液中的水和懸浮氣泡明顯降低了運動副間油膜的強度，使?jié)櫥阅芙档汀?污染物的種類：污染物是液壓系統(tǒng)油液中對系統(tǒng)起危害作用的的物質(zhì)，它在油液中以不同的形態(tài)形式存在，根據(jù)其物理形態(tài)可分成：固態(tài)污染物、液態(tài)污染物、氣態(tài)污染物。固態(tài)污染物可分成硬質(zhì)污染物，有：金剛石、切削、硅沙、灰塵、磨損金屬和金屬氧化物；軟質(zhì)污染物有：添加劑、水的凝聚物、油料的分解物與聚合物和維修時帶入的棉絲、纖維。液態(tài)污染物通常是不符合系統(tǒng)要求的切槽油液、水、涂料和氯及其鹵化物等，通常我們難以去掉，所以在選擇液壓油時要選擇符合系統(tǒng)標準的液壓油，避免一些不必要的故障。HR液壓油是在環(huán)境溫度變化大的中低壓液壓系統(tǒng)中使用的液壓油。</p><div

5）檢查所有管路尺寸是否合適，連接是否正確。流量控制閥包括節(jié)流閥、調(diào)整閥、分流集流閥等。淄博柴油機液壓系統(tǒng)規(guī)格</p><p style="text-indent:25px">生物降解液壓油是為了適應(yīng)環(huán)保要求，控制環(huán)境污染而開發(fā)的。淄博柴油機液壓系統(tǒng)規(guī)格</p><p
