萊寶擴散泵油LVO 500 用于萊寶擴散泵DIP系列專用油。
LEYBONOL pump fluids for oil diffusion pumps must exhibit a low vapor pressure at room temperature
and must be able to resist thermal decomposition and oxidization. They permit high pumping speeds
over a wide range of pressures.
Surface tension of the pump fluids must be high to reduce "creep" of oil films. They are chemically inert,
exhibit a high flash point and the evaporation heat is low.
