Oil pump works

In the vacuum pump vacuum pump oil , not only as a medium to get , but also on the mechanical friction point lubrication , cooling and sealing.

1 low vapor pressure
 This is the most important properties of the oil pump , the vacuum pump requires a high degree , usually with narrow fractions of paraffinic oil , the diffusion pump , a low vapor pressure can also use a silicone oil or other synthetic oils.

2 . Appropriate viscosity and good viscosity-temperature characteristics
  Vacuum cavity formed by the exhaust volume changing role requirements should have the right lubricant viscosity and viscosity-temperature characteristics .

3 Good thermal oxidation stability
  Vacuum pump to keep the high-speed development , due to the rapid slide friction and pump the oil temperature rise , oil is easily oxidized and decomposed , in particular, are often in a diffusion pump under high temperature environment to work within the system so that the vapor pressure, reducing the degree of vacuum , vacuum pump oil thus requiring good thermal oxidative stability .

4 good corrosion resistance and resistance to emulsification
  If inhaled pump corrosive gases will react chemically with the oil , corrosion pump parts ; inhalation of air containing water vapor tends to condense water , causing the vacuum pump oil emulsion and makes metal corrosion , it is required to have good anti- corrosion and anti- emulsification sex .

5 high flash
 The main requirements of the vacuum pump does not carry the light components , so as not to affect the saturated vapor pressure of the oil .

6 The lower limit pressure
  Vacuum pump oil pressure is important to limit the use of performance indicators to understand the extreme pressure at the lowest vacuum pump ultimate pressure .
