矿用进口润滑油美孚齿轮油632的替代性研究

In recent years, the mechanized degree of the mining equipment is more and more high, the design and structure of the mechanical equipments are increasingly precise and complicated. Mechanical equipments breaking down has become an important threatening to the safe production of the mine due to neglecting of the maintain of the lubricant. Now most mechanical equipments use the overseas lube, especially the input equipments. Although the result is very good, the expensive price have been a big obstacle to the development of mineral industry. Most mines expect that the homemade lube can satisfy the usage of our own mineral mechanical equipments, promote the development of our mineral industry by reducing the outflow of funds. For gear oil, its main performance indicators are the kinematic viscosity, wear resistance, corrosion resistance etc. In this paper, consulting the performance index of oil imports and combining the special usage of the coal mine, on the basis of the kinematic viscosity, wear resistance, corrosion resistance properties of the imports Mobil 632 lube, this study selected a suitable domestic lubricants-Changcheng SH5320 and carried out contrastive researches. The experimental results show that both Mobil 632 and Changcheng SH5320 have similar properties, per liter of Changcheng SH5320 can save more than 30 yuan compared with Mobil 632, so it is feasible for Changcheng SH5320 to alternate Mobil 632.
