液壓系統簡介

　　液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)系(xi)統(tong)(tong)(tong)(tong)可分為兩(liang)類：液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)傳動(dong)系(xi)統(tong)(tong)(tong)(tong)和液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)控制(zhi)系(xi)統(tong)(tong)(tong)(tong)。液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)傳動(dong)系(xi)統(tong)(tong)(tong)(tong)以(yi)傳遞動(dong)力和運(yun)動(dong)為主(zhu)要(yao)功能(neng)。液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)控制(zhi)系(xi)統(tong)(tong)(tong)(tong)則要(yao)使液(ye)(ye)(ye)(ye)(ye)壓(ya)(ya)系(xi)統(tong)(tong)(tong)(tong)輸(shu)出滿足特定的性(xing)能(neng)要(yao)求(qiu)、特別是動(dong)態性(xing)能(neng)。

　　一個完整(zheng)的液壓系統由五個部分(fen)組成，即動力元件(jian)(jian)、執行元件(jian)(jian)、控制元件(jian)(jian)、輔助元件(jian)(jian)和液壓油。

　　1、動(dong)力元件的作用是(shi)將原(yuan)動(dong)機的機械能(neng)轉(zhuan)換(huan)成液(ye)體的壓力能(neng)，指液(ye)壓系(xi)統中的油泵(beng)，它向(xiang)整個液(ye)壓系(xi)統提供動(dong)力。

　　2、執行元件的(de)作用是將液體的(de)壓力(li)能轉換為機(ji)械能，驅動負載作直線往(wang)復運動或回轉運動。

　　3、控(kong)(kong)(kong)制(zhi)元件在液(ye)壓(ya)系統中控(kong)(kong)(kong)制(zhi)和(he)(he)調節液(ye)體的(de)壓(ya)力、流(liu)量和(he)(he)方向。根據控(kong)(kong)(kong)制(zhi)功(gong)能(neng)的(de)不同，液(ye)壓(ya)閥(fa)可分為壓(ya)力控(kong)(kong)(kong)制(zhi)閥(fa)、流(liu)量控(kong)(kong)(kong)制(zhi)閥(fa)和(he)(he)方向控(kong)(kong)(kong)制(zhi)閥(fa)。

　　4、輔助元件包括油(you)(you)箱、濾油(you)(you)器(qi)(qi)、冷卻器(qi)(qi)、加熱器(qi)(qi)、蓄能器(qi)(qi)、油(you)(you)管及管接頭、高壓球閥、壓力表、油(you)(you)位(wei)計(ji)、油(you)(you)溫計(ji)等(deng)。

　　5、液壓(ya)(ya)油(you)是液壓(ya)(ya)系(xi)統(tong)中(zhong)傳遞能量的工作介質，有各種(zhong)礦(kuang)物油(you)、乳化液和合成型(xing)液壓(ya)(ya)油(you)等(deng)幾大(da)類。

　　液壓系(xi)統(tong)主要應(ying)用于(yu)電力、建材、石化、冶金等行(xing)業大中型工業生產機械設備。
