OIL CHANGING KNOWLEDGE OF WATER RING VACUUM PUMP

THE USE OF WATER RING VACUUM PUMP OIL:

Vacuum pump oil has the same function as ordinary lubricating oil, but the water content of vacuum pump is lower than that of ordinary lubricating oil, because the water evaporates back at high vacuum and occupies the pump displacement and the performance of vacuum pump decreases.

THE MAIN FUNCTION OF WATER RING VACUUM PUMP OIL :

In the process of using thermal conductive oil pump, because the vacuum pump oil directly into the pump chamber, when the vacuum pump runs, with the gas pressure gradually reduced, the pump temperature gradually increased. Molecular components with high saturated vapor pressure in oil products can evaporate into the vacuum space, which affects the reaching of the vacuum pump limit pressure, and can diffuse back to the vacuum system, causing pollution.
