淺談液壓系統(tǒng)流量損失、壓力損失和液壓沖擊

液壓系統(tǒng)的流量損失、壓力損失和液壓沖擊。

1、流量損失

在液壓站中，各液壓元件都有相對(duì)運(yùn)動(dòng)的表面，如液壓油缸內(nèi)表面和活塞外表面，因爲(wèi)要有相對(duì)運(yùn)動(dòng)，所以它們之間都有一定的間隙。如果間隙的一邊爲(wèi)高壓油，另一邊爲(wèi)低壓油，則高壓油就會(huì)經(jīng)間隙流向低壓區(qū)從而造成洩漏。同時(shí)，由于液壓元件密封不完善，一部分油液也會(huì)向外部洩漏。這種洩漏造成的實(shí)際流量有所減少，這就是我們所說的流量損失。

流量損失影響運(yùn)動(dòng)速度，而洩漏又難以絕對(duì)避免，所以在液壓系統(tǒng)中泵的額定流量要略大于系統(tǒng)工作時(shí)所需的******流量。通常也可以用系統(tǒng)工作所需的******流量乘以一個(gè)1.1~1.3的系數(shù)來估算。

2、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)爲(wèi)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)，因摩擦而産生的壓力損失。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******工作壓力，一般可將系統(tǒng)工作所需的******工作壓力乘以一個(gè)1.3~1.5的系數(shù)來估算。3、液壓沖擊

原因：執(zhí)行元件換向及閥門關(guān)閉使流動(dòng)的液體因慣性和某些液壓元件反應(yīng)動(dòng)作不夠靈敏而産生瞬時(shí)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(dòng)，産生噪聲；使繼電器、順序閥等壓力元件産生錯(cuò)誤動(dòng)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(shí)間，估算出壓力峰值，采用相應(yīng)措施。如將流動(dòng)換向閥和電磁換向閥聯(lián)用，可有效地防止液壓沖擊。
