摘要：

The possible reasons of an explosion during the process of filling oxygen cylinder were analyzed in this article. And finding the grease in the cylinder may be the main cause of this incident. Using three kinds of lubricating oil as the experimental grease were experimented in combustion reaction under different pressure of oxygen by PTG. The relationship between the increment of lubricating oils' mass, ignition point, combustion rate and the pressure of oxygen were derived from the TG and DTG curve (TG-DTG curve). Experimental results show that the oil oxidation increment increase and the ignition point decrease with the pressure of oxygen escalating, and the higher pressure of oxygen, the lower combustion rate. In addition, the fact was confirmed that the lubricants additives have an effect on combustion characteristics of lubricating oil in high-pressure oxygen.
