First to choose the vacuum pump oil, 1#, 3#, 100# can! If the requirements are not high enough to replace the use of general oil vacuum pump oil (do not affect the use). Oil has a certain viscosity, viscosity of the concave and convex resolution of the vacuum pump sealing, viscosity is too small, sealing is not good.
Too high viscosity, will increase the conflict between the pump blade and cylinder, smooth effect will become worse, together, the rotor rotation will become difficult, the motor pressure will become high, the oil temperature will become higher and higher. The increase of oil temperature will accelerate the emulsification degree of pump oil and affect the vacuum degree of concavity.
The full volume vapor pressure of vacuum pump oil is low, the light distillation is less. If is the general vacuum pump oil or oil is very simple evaporation, the use of non-vacuum pump special oil is often in the face of refueling situation. Vacuum pump special oil chemical properties tend to be more stable, the content of water, water soluble acid, insoluble alkali and other impurities is much smaller, the use of special oil energy to avoid repeated replacement of vacuum pump oil and ensure the cleanliness of the pump.
From the above points can be seen, the use of regular vacuum pump special oil can be useful to avoid the pump oil emulsification, carbonization and other elements of vacuum pump bad gas, fundamentally deal with the vacuum pump maintenance difficulty, improve the vacuum pump service life.
How often do I have to fill up? Disc vacuum pump has an audition, in the vacuum pump box side, the naked eye can be investigated. Refueling every time the demand to add to the middle line of the orientation of the audition, not more, more will make the work of the state of oil may oil phenomenon. Natural oil lack of ordinary remember to make up for good.
