液壓傳(chuan)動(dong)中(zhong)用來(lai)控(kong)制液體壓力、流(liu)量和方(fang)向的(de)元件。其中(zhong)控(kong)制通、斷和流(liu)向的(de)稱為方(fang)向控(kong)制閥。
方向(xiang)控制(zhi)閥(fa)按(an)用(yong)途分為單向(xiang)閥(fa)和換向(xiang)閥(fa)。
1、單向(xiang)閥：只允許流體(ti)在(zai)管道(dao)中單向(xiang)接通(tong)，反向(xiang)即切(qie)斷。
2、換向閥(fa)：改變不同管(guan)路間的(de)通(tong)(tong)(tong)、斷關系、根據(ju)閥(fa)芯在(zai)閥(fa)體中的(de)工作位(wei)(wei)置數(shu)分(fen)兩位(wei)(wei)、三位(wei)(wei)等；根據(ju)所(suo)控制的(de)通(tong)(tong)(tong)道數(shu)分(fen)兩通(tong)(tong)(tong)、三通(tong)(tong)(tong)、四通(tong)(tong)(tong)、五通(tong)(tong)(tong)等；如二位(wei)(wei)二通(tong)(tong)(tong)、三位(wei)(wei)三通(tong)(tong)(tong)，三位(wei)(wei)五通(tong)(tong)(tong)等根據(ju)閥(fa)芯驅動(dong)(dong)方式(shi)分(fen)手動(dong)(dong)、機(ji)動(dong)(dong)、電磁、液動(dong)(dong)等。
60年代(dai)后(hou)期(qi)，在上(shang)述幾種液壓(ya)控(kong)(kong)制(zhi)閥的基礎上(shang)又研制(zhi)出電液比例控(kong)(kong)制(zhi)閥。它的輸出量(壓(ya)力(li)、流量)能(neng)隨輸入的電信號連續(xu)變化。電液比例控(kong)(kong)制(zhi)閥按作用不同(tong)，相(xiang)應地(di)分為電液比例壓(ya)力(li)控(kong)(kong)制(zhi)閥、電液比例流量控(kong)(kong)制(zhi)閥和(he)電液比例方向控(kong)(kong)制(zhi)閥等。

1、油(you)(you)(you)箱要(yao)(yao)達到(dao)規定的(de)質量要(yao)(yao)求。油(you)(you)(you)箱上附件必(bi)須齊全。箱內部(bu)不準有銹蝕(shi)，裝(zhuang)油(you)(you)(you)前油(you)(you)(you)箱內部(bu)一定要(yao)(yao)清(qing)洗(xi)干(gan)凈。
2、所領用的濾油器型號規格(ge)與設(she)計要求必(bi)須一致，確認濾芯精(jing)度等級，濾芯不得有缺陷，連(lian)接螺(luo)口不準有破(po)損，所帶附(fu)件必(bi)須齊全。
3、各種密封件(jian)(jian)外觀質量(liang)要符合要求，并查明所(suo)領(ling)密封件(jian)(jian)保(bao)管期限。有異(yi)常或保(bao)管期限過長的密封件(jian)(jian)不準使用(yong)。
4、蓄能器質(zhi)量(liang)要(yao)符(fu)合(he)要(yao)求，所帶附件要(yao)齊全。查明保管期(qi)限，對存(cun)放過長的蓄能器要(yao)嚴(yan)格(ge)檢查質(zhi)量(liang)，不(bu)符(fu)合(he)技術(shu)指標和使用要(yao)求的蓄能器不(bu)準使用。
5、空氣(qi)(qi)濾(lv)清(qing)器用(yong)于過濾(lv)空氣(qi)(qi)中的粉塵，通(tong)(tong)氣(qi)(qi)阻力(li)不能(neng)太大(da)，保證箱內壓力(li)為大(da)氣(qi)(qi)壓。所以(yi)空氣(qi)(qi)濾(lv)清(qing)器要有足夠大(da)的通(tong)(tong)過空氣(qi)(qi)的能(neng)力(li)。

液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)站又稱(cheng)為液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)站，系(xi)統(tong)元件(jian)主要是(shi)由液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)、液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)缸、液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)馬達、液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)閥等構成的(de)。液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)是(shi)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)系(xi)統(tong)的(de)心臟，簡稱(cheng)油泵(beng)。在(zai)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)系(xi)統(tong)中，一(yi)定至少(shao)有一(yi)個泵(beng)。液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)泵(beng)是(shi)一(yi)種能量轉(zhuan)換裝置，它的(de)作(zuo)用是(shi)使液(ye)(ye)(ye)(ye)體發生運動，把機械(xie)能轉(zhuan)換成流體能（也叫做(zuo)液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)能）。液(ye)(ye)(ye)(ye)壓(ya)(ya)(ya)(ya)(ya)系(xi)統(tong)
泵是(shi)液壓(ya)(ya)傳動(dong)(dong)(dong)系(xi)統中的動(dong)(dong)(dong)力(li)元(yuan)件，由(you)原(yuan)動(dong)(dong)(dong)機驅(qu)動(dong)(dong)(dong)，從原(yuan)動(dong)(dong)(dong)機的輸出功(gong)(gong)率中取(qu)出機械(xie)能(neng)，為系(xi)統提供壓(ya)(ya)力(li)油液。然后，在需要(yao)做功(gong)(gong)的場所，由(you)執(zhi)行(xing)元(yuan)件（液壓(ya)(ya)缸或液壓(ya)(ya)馬達(da)）再把流體壓(ya)(ya)力(li)能(neng)轉換成機械(xie)能(neng)輸出。
