液(ye)(ye)(ye)壓(ya)(ya)油冷(leng)(leng)卻(que)循環系(xi)統(tong)工(gong)作不(bu)良通常(chang)，采用水冷(leng)(leng)式(shi)或風(feng)冷(leng)(leng)式(shi)油冷(leng)(leng)卻(que)器(qi)對(dui)液(ye)(ye)(ye)壓(ya)(ya)系(xi)統(tong)的(de)油溫(wen)進行強制性降(jiang)溫(wen)。水冷(leng)(leng)式(shi)冷(leng)(leng)卻(que)器(qi)，會(hui)因散熱(re)(re)片太(tai)臟或水循環不(bu)暢而(er)使其(qi)散熱(re)(re)系(xi)數(shu)降(jiang)低；風(feng)冷(leng)(leng)式(shi)冷(leng)(leng)卻(que)器(qi)，會(hui)因油污過多而(er)將(jiang)冷(leng)(leng)卻(que)器(qi)的(de)散熱(re)(re)片縫隙堵塞，風(feng)扇(shan)難以對(dui)其(qi)散熱(re)(re)，結果導致油溫(wen)升高(gao)。預防措施(shi)：定期檢查和維護液(ye)(ye)(ye)壓(ya)(ya)油冷(leng)(leng)卻(que)循環系(xi)統(tong)，液(ye)(ye)(ye)壓(ya)(ya)油多少(shao)錢一(yi)升，一(yi)旦(dan)發現故障，必須立即停機排除。

油(you)(you)(you)溫(wen)(wen)(wen)升(sheng)高(gao)(gao)的主(zhu)要原因1、首先是工作(zuo)(zuo)環(huan)境(jing)溫(wen)(wen)(wen)度過高(gao)(gao)，通(tong)風(feng)條件(jian)太差，造成油(you)(you)(you)溫(wen)(wen)(wen)極易升(sheng)高(gao)(gao)。所(suo)以應盡量避開高(gao)(gao)溫(wen)(wen)(wen)時(shi)間點作(zuo)(zuo)業。如果條件(jian)允許(xu)，請在液壓(ya)(ya)系統(tong)回(hui)油(you)(you)(you)管路，加(jia)裝風(feng)冷式液壓(ya)(ya)油(you)(you)(you)散(san)熱(re)(re)器，對液壓(ya)(ya)系統(tong)進行物(wu)理降溫(wen)(wen)(wen)。2、液壓(ya)(ya)油(you)(you)(you)箱太小(xiao)或者油(you)(you)(you)位太低，液壓(ya)(ya)油(you)(you)(you)沒有(you)足夠的循環(huan)條件(jian)及冷卻條件(jian)。液壓(ya)(ya)油(you)(you)(you)工作(zuo)(zuo)過程中(zhong)，主(zhu)要通(tong)過液壓(ya)(ya)油(you)(you)(you)箱散(san)熱(re)(re)。油(you)(you)(you)箱面積(ji)越大(da)，越利于散(san)熱(re)(re)。

在(zai)工(gong)作條件惡(e)劣的(de)場合，為保證系(xi)統的(de)，要選用粘(zhan)溫特性(xing)、熱穩(wen)定性(xing)、潤滑性(xing)以及防銹蝕等性(xing)能好(hao)的(de)油(you)液(ye)(ye)(ye)。3、根據密封(feng)材(cai)料選擇。液(ye)(ye)(ye)壓(ya)裝置的(de)密封(feng)件材(cai)質與系(xi)統所使(shi)用的(de)油(you)液(ye)(ye)(ye)相容(rong)(rong)，32號液(ye)(ye)(ye)壓(ya)油(you)價格，否則(ze)密封(feng)件在(zai)會出現膨(peng)脹、收縮(suo)、侵蝕、溶解等現象(xiang)，蕪湖(hu)液(ye)(ye)(ye)壓(ya)油(you)，造成系(xi)統性(xing)能下降，如(ru)HM抗磨液(ye)(ye)(ye)壓(ya)油(you)與天然橡(xiang)(xiang)膠、丁(ding)基橡(xiang)(xiang)膠、乙烯橡(xiang)(xiang)膠、硅橡(xiang)(xiang)膠等相容(rong)(rong)性(xing)較差(cha)，這點在(zai)實(shi)際使(shi)用當中(zhong)是要予以重視的(de)。
