Vacuum pump oil plays an important role in the safety of vacuum system. High quality vacuum pump oil can show high oxidation resistance, good thermal stability, lubricity, sealing performance and low chemical activity. In addition, no volatile pollutants, no moisture absorption, high boiling point, low vapor pressure, long service life, renewable, these are the performance indicators to evaluate high quality vacuum pump oil.
I. performance analysis of vacuum pump oil
1. Sealing performance analysis: in order to prevent the exhaust valve from entering the atmosphere, there is a gap between the relative moving parts (rotor and stator, rotor and rotor, slot, etc.). .
2. Lubrication performance analysis: relative lubrication between moving parts to reduce wear.
3. Performance analysis: the oil circulates between the pump and the tank to dissipate heat.
4. Analysis of bearing and wrapping performance: dust particles or other abrasive particles are wrapped in oil to reduce abrasion damage.
5. Protection performance analysis: forming protective oil film to prevent water and chemical vapor condensate from corroding the internal parts of the pump.
Ii. Inspection performance required for vacuum pump oil
1. At high temperature, the saturated vapor pressure is lower and the volatile components are less.
2. Minimum water content and water absorption.
3. Must have a certain viscosity, with little change with temperature (viscosity temperature rise curve is smooth).
4. Good lubrication performance, good crack resistance under mechanical stress.
5. Corrosion resistance, oxidation resistance and stable chemical properties.
Three, vacuum pump oil test standards
Viscosity grade, kinematic viscosity, density, flash point, pour point, neutralization value, chroma, residual carbon, demulsibility, corrosion test, foam performance, oxidation stability, water-soluble acid and base test, moisture content, mechanical impurities, saturated vapor pressure, limit pressure
