Development and classification of imported vacuum pump oil
After many years of polishing, China's vacuum technology has made rapid development. At present, it has become an independent basic science with the continuous development of many industrial companies, such as aerospace science, vacuum coating, vacuum smelting, high energy physics, controlled thermonuclear reaction, surface research, etc. The progress of science and vacuum technology is interdependent. As a special lubricating oil for various mechanical vacuum pumps, the imported vacuum pump oil plays the functions of lubrication, sealing and cooling in the vacuum pump.
Because the mechanical vacuum pump has different models, so the vacuum pump oil must also have suitable viscosity, excellent oil-water separation, good thermal stability and oxidation stability, as low as possible saturated vapor pressure, because the quality of vacuum pump oil indirectly affects the limit pressure, pumping rate, back pressure and oil return rate of vacuum pump equipment. In recent years, with the continuous development of vacuum technology, mechanical vacuum pump develops to high speed, low noise and miniaturization. The linear velocity of the friction pair surface in the pump cavity increases, and the oil temperature rises. Because the mechanical vacuum pump oil tends to be low viscosity, it is required to maintain a low vapor pressure under the working temperature of the pump.
