【Abstract】 The water - proof vacunm pump oil was formulated by the base oil made by specific feedstockand technique and selected additives such as VII, emulsion inhibitor, oxidation stabilizer, antirust additive andanti - friction agent. The evaluation showed that this oil is better than the present vacuum pump oil in oil- water separativeness, oxidation stability, antirust and antifoaming properties, is suitable for lubricating machanismwhich steam is easy to get into its vacuum system. There is a better economic benefit in practical service.更多还原
