工程機械油，指專業用于挖掘機、裝載機、吊裝機、叉車、起重機、混凝土攪拌機及壓路機等機械設備的專用潤滑油。主要包括柴油機油、抗磨液壓油、重負荷齒輪油、液力傳動油等共四大類。那么該如何選擇合適的工程機械油呢？ 拓牌工程機械潤滑油

      環境(jing)溫(wen)度(du)：如果(guo)設備經常在高溫(wen)環境(jing)下運行，應選擇(ze)高粘度(du)的(de)油品，例如 20W50。在北方冬季使用時(shi)，應選擇(ze)低(di)溫性能更好(hao)的(de)油品。

      負荷：對于大噸位、重負荷、連續高速運轉的工程機械，應選擇高粘度油，以在高溫時提供足夠的油膜強度。對于負荷較小、工況緩和的小型機械設備，可以使用較低黏度牌號的柴油機油。拓牌工程機械潤滑油

      設(she)備新舊：對于新設(she)備，由(you)于各部件配合(he)間隙(xi)較小(xiao)，可以選擇低粘度(du)油。 然而，對于舊設備，由于存在一定程度的磨損，配合間隙較大，因此需要使用更高黏度的油品才能達到更好的密封要求，所以舊設備一般使用更高黏度的油品。拓牌工程機械潤滑油
