Industry insiders recently said that the impact of the new crown pneumonia epidemic on the global lubricant market demand is almost the same as that of the 2008 global financial crisis. However, it is too early to predict the final impact, as it depends on how long the outbreak will be contained and the economic recovery will last.

China Petroleum News "The era of easy exploitation of oil and gas has come to an end, and the sustainable development of the oil and gas industry is increasingly dependent on technological innovation. In 2012, the number of first patent applications in the global oil and gas field reached a peak of 25,807, and patent applications with priority in China accounted for 25,807. 54%. China has become the main force of technology research and development in the global oil and gas field.” On September 18, China Petroleum Economic and Technological Research Institute, the largest petroleum economic technology information resource center in China, released the “Foreign Petroleum Technology Development Report (2014)” in Beijing. (hereinafter referred to as the "Report").

When the operating temperature of the bearing increases by 10~15℃, the bearing life of the grease will be reduced by half; select the grease for high temperature and focus on the performance of the dropping point, evaporation, oxidation stability and high temperature baking test of the grease. The selection of low temperature grease should pay attention to the similar viscosity and low temperature torque at low temperature. Effect of temperature on oxidation rate

Correctly lubricating the open gear is a necessary condition to ensure the normal operation of the gear, to ensure that the open gear obtains the best bearing capacity and smooth transmission, correct processing and manufacturing, and accurate alignment of the transmission device. So how to choose the correct starting gear grease?
