Methods for studying residual mist treatment in oil mist lubrication

Thread Content

The main lubrication methods commonly used in daily production are dry oil lubrication and thin oil lubrication. Oil lubrication is mainly applied to various bearings that operate at low speeds, frequently reverse direction, and perform short-term tasks repeatedly, as well as to components for which it is difficult to achieve reliable sealing using rare lubricants ； Light oil lubrication is generally used in equipment that operates for long periods under heavy loads and at high speeds. With the development and advancement of technology, humanity’s demand for energy is increasing, and the consumption of power sources is particularly essential. According to statistics, the world consumes 1.5 billion tons per year of gasoline, diesel, natural gas, coal, and other fuels, with approximately 50% to 60% of this energy consumption being used by various power machinery. Due to technical limitations, the energy utilization rate of power machinery is on average only around 30%. According to calculations by Professor Vo.Gelpohl of Germany. One-third to one-half of the energy produced worldwide is lost due to friction and wear. In recent years, Professor H.P. J06t in the UK has pointed out that 30%–40% of the world’s energy consumption is spent on friction and wear; in other words, around 2 billion tons of oil’s worth of energy is wasted each year as a result of friction and wear worldwide. At the same time, as mechanical applications become increasingly widespread, especially in complex and harsh environments where high loads and high speeds are required, this poses certain difficulties and challenges in terms of the management and maintenance of equipment lubrication. The existing lubrication methods can no longer meet the new lubrication requirements of such equipment. Oil mist lubrication is a new type of efficient lubrication method that lies between thin oil lubrication and dry grease lubrication. It has been successfully applied to various friction pairs such as rolling bearings, sliding bearings, gears, worm gears, chains, and moving guides in rolling mills and aluminum foil rolling mill production lines within the metallurgy industry. It is also widely used in the petrochemical industry, particularly in the rolling bearings and sliding bearings of pumps used in production areas such as catalytic units and gas separation units. It exhibits great advantages in improving the operating conditions and performance of friction pairs, as well as in saving energy and reducing environmental pollution.
