真空泵油性能特征
Performance characteristics of vacuum pump oil
氧化稳定性：长期在高温条件下与空气、树脂、化学原料等直接接触亦不易变质，减少有害漆膜和油垢的形成，提供较长的换油周期。
Oxidation stability: it is not easy to deteriorate in long-term direct contact with air, resin, chemical raw materials, etc. under high temperature conditions, so as to reduce the formation of harmful paint film and oil scale, and provide a long oil change period.
防锈防腐蚀性：能在金属表面形成非常有效的防腐膜，从而可以全面防止因吸入腐蚀性气体和水分而导致的系统腐蚀。
Rust and corrosion resistance: it can form a very effective anti-corrosion film on the metal surface, so as to completely prevent the system corrosion caused by inhaling corrosive gas and water.
能迅速将油液中夹带的水分分离出来，达到所需的真空度。
It can quickly separate the water contained in the oil to achieve the required vacuum degree.
具较底的蒸汽压，防止油品从泵的内腔向真空系统返流扩散造成返油。从而保证有足够的极限真空。
It has a lower vapor pressure to prevent the oil from flowing back from the inner cavity of the pump to the vacuum system and causing oil return. So as to ensure enough limit vacuum.
