style="text-indent:25px">電氣實(shí)驗(yàn)臺(tái)常見故障維修：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(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。總的壓力損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)來估算。重慶電氣安裝與調(diào)試實(shí)驗(yàn)臺(tái)批發(fā)電氣實(shí)驗(yàn)臺(tái)CPU的連接，便于實(shí)現(xiàn)自動(dòng)化。</p><div

style="text-indent:25px">電氣實(shí)驗(yàn)臺(tái)是一種以液體為工作介質(zhì)，用來傳遞能量以實(shí)現(xiàn)各種工藝的機(jī)器。電氣實(shí)驗(yàn)臺(tái)除用于鍛壓成形外，也可用于矯正、壓裝、打包、壓塊和壓板等。電氣實(shí)驗(yàn)臺(tái)包括水壓機(jī)和油壓機(jī)。以水基液體為工作介質(zhì)的稱為水壓機(jī),以油為工作介質(zhì)的稱為油壓機(jī)。電氣實(shí)驗(yàn)臺(tái)的規(guī)格一般用公稱工作力或公稱噸位表示。鍛造用電氣實(shí)驗(yàn)臺(tái)多是水壓機(jī)，噸位較高。為減小設(shè)備尺寸，大型鍛造水壓機(jī)常用較高壓強(qiáng)，有時(shí)也采用100兆帕以上的超高壓。其他用途的電氣實(shí)驗(yàn)臺(tái)一般采用6～25兆帕的工作壓強(qiáng)。油壓機(jī)的噸位比水壓機(jī)低。</p><p style="text-indent:25px">電氣實(shí)驗(yàn)臺(tái)的維護(hù)要領(lǐng)：電氣實(shí)驗(yàn)臺(tái)緊固件要定期進(jìn)行鎖緊。試樣拉斷后的振動(dòng)經(jīng)常會(huì)使一些緊固件退松，一定要定期進(jìn)行巡檢(正常使用三十個(gè)工作日左右)，以避免由于緊固件松動(dòng)造成大的損失。其他檢查：提高警惕并密切注意細(xì)節(jié)，可以及早發(fā)現(xiàn)事故苗頭，防止釀成大的事故。在設(shè)備當(dāng)初投入運(yùn)行的時(shí)候尤其是這樣。應(yīng)該始終注意外泄漏、污染物、元器件損壞以及來自泵、聯(lián)軸器等的異常噪聲。配備液體增壓泵，可輕松實(shí)現(xiàn)輸出壓力任意可調(diào)、可控，具有可記憶性儀表，記錄瞬間爆破壓力。實(shí)驗(yàn)臺(tái)是實(shí)驗(yàn)室中比較常見的一種設(shè)備。</p><div
