style="text-indent:25px">減壓閥一般設(shè)在執(zhí)行元件支路接口處；減壓閥主要是用來(lái)降低液壓系統(tǒng)某一分支油路的壓力，使分支壓力比主油路壓力低且穩(wěn)定，在調(diào)定壓力的范圍內(nèi)，減壓閥也像溢流閥那樣是關(guān)閉的。但是隨著系統(tǒng)壓力的升高當(dāng)達(dá)到減壓閥調(diào)定的壓力時(shí)，減壓閥打開(kāi)，部分油液會(huì)經(jīng)過(guò)他返回油箱（此時(shí)有一定壓力的油回油箱，油箱的油溫會(huì)上升），這一支路的油壓是不會(huì)上升了。它起到對(duì)本支路的減壓與穩(wěn)壓作用，減壓閥是保持出口壓力基本不變，而溢流閥保持進(jìn)口壓力基本不變,在不工作時(shí)減壓閥進(jìn)出口壓力互通，而溢流閥進(jìn)出口不同。為了保證減壓閥出口壓力調(diào)定值恒定，它的先導(dǎo)彈簧腔需通過(guò)卸油口單獨(dú)外接回油箱。而溢流閥反之。木屑設(shè)備液壓系統(tǒng)怎么樣動(dòng)力元件的作用是將原動(dòng)機(jī)的機(jī)械能轉(zhuǎn)換成液體的壓力能。</p><div

style="text-indent:25px">其實(shí)溢流閥分為直動(dòng)式跟先導(dǎo)式兩種的。直動(dòng)式結(jié)構(gòu)簡(jiǎn)單，制造精度要求不高，成本低。阻力小，動(dòng)作靈敏。缺點(diǎn)就是壓力滯后比較嚴(yán)重，容易產(chǎn)生振動(dòng)，控制壓力受溢流量的影響較大，因此不能用在高壓和大流量的系統(tǒng)里，而先導(dǎo)式溢流閥則相反。溢流閥一般是用在并聯(lián)在系統(tǒng)的進(jìn)油旁路中起調(diào)壓、穩(wěn)壓與減壓作用；防止系統(tǒng)超載,保證安全。減壓閥分定值，定差和定比等三種；其中常見(jiàn)的就是定值減壓閥。如不指明通常說(shuō)的減壓閥都是定值減壓閥。按安裝結(jié)構(gòu)可分為疊加式跟直裝式和管式減壓閥；一般情況下管式的比較少用。按工作形式可分為先導(dǎo)式跟直動(dòng)式兩種。</p><p style="text-indent:25px">測(cè)壓力首先將檢測(cè)回路的軟管接頭與雙球閥三通螺紋接口旋緊接通。打開(kāi)球閥，關(guān)死溢流閥，切斷回油通道，這時(shí)從壓力表上可直接讀出所測(cè)點(diǎn)的壓力值（為系統(tǒng)的實(shí)際工作壓力）。測(cè)流量和溫度慢慢松開(kāi)溢流閥7手柄，再關(guān)閉球閥1。重新調(diào)整溢流閥7，使壓力表4讀數(shù)為所測(cè)壓力值，此時(shí)流量計(jì)讀數(shù)即為所測(cè)點(diǎn)的實(shí)際流量值。同時(shí)溫度計(jì)6上可顯示出油液溫度值。測(cè)轉(zhuǎn)速（速度）不論泵、馬達(dá)或缸其轉(zhuǎn)速或速度*取決于兩個(gè)因素，即流量和它本身的幾何尺寸（排量或面積），所以只要測(cè)出馬達(dá)或缸的輸出流量（對(duì)泵為輸入流量），除以其排量或面積即得到轉(zhuǎn)速或速度值。液壓缸零件材料如果制造液壓缸的材料具有較好的強(qiáng)度、韌性及抗腐蝕性。</p><div

style="text-indent:25px">壓力損失由于液體具有黏性，在管路中流動(dòng)時(shí)又不可避免地存在著摩擦力，所以液體在流動(dòng)過(guò)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(guò)一段距離時(shí)，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(shí)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(gè)1.3~1.5的系數(shù)來(lái)估算。液壓元件在長(zhǎng)期高速運(yùn)轉(zhuǎn)下，零部件間配合間隙就會(huì)變大，元件泄漏量也會(huì)增大。蘇州液壓系統(tǒng)哪家專業(yè)</p><p
