In the vacuum pump vacuum pump oil not only as a vacuum medium, but also on the mechanical friction point lubrication, cooling and sealing effect. Main performance requirements: 1. Very low vapor pressure This is the most important performance of vacuum pump oil, the vacuum pump requires a high degree of vacuum, the general paraffin-based narrow-cut lubricant, for the diffusion pump, you can also use a very low vapor pressure Silicone oil or other synthetic oil. 2. Appropriate viscosity and good viscosity-temperature characteristics Vacuum chamber volume changes evolving evacuation, requiring lubricating oil should have the appropriate viscosity and viscosity-temperature characteristics. 3. Good thermal oxidation stability Vacuum pumps continue to develop to a high speed. Due to the high temperature friction between the vanes and the pump body, the oil is easily oxidized and decomposed. In particular, diffusion pumps often work under very high temperature conditions, Make systematic vapor pressure rise, the degree of vacuum is reduced, therefore require vacuum pump oil to have good thermal oxidation stability. 4. Good corrosion resistance and anti-emulsification Vacuum pump inhaled if it is corrosive gas, will react with the oil, corrosion pump parts; inhaled air often contains water vapor condensation, causing the vacuum pump oil emulsion and the metal corrosion , It is required to have good anti-corrosion and anti-emulsification. 5. The higher flash point mainly requires the vacuum pump does not carry light components, so as not to affect the saturated vapor pressure of the oil. 6. Lower limit pressure The ultimate pressure is an important performance indicator of vacuum pump oil to understand the ultimate pressure of the vacuum pump at the lowest vacuum limit pressure.
