Due to the adjustment of process,the HVIS500 base oil,which was always used to produce 100# vacuum pump oil in PetroChina Dalian Petrochemical Co.
中国石油大连石化分公司100#真空泵油的生产是以HVIS500基础油为原料进行的,由于生产调整,已经不再生产HVIS500基础油,而在生产3#扩散泵油时,分子蒸馏和薄膜脱气工序产生的拔头油,与HVIS400和HVI650基础油按一定比例调合而成的HVIS500基础油,经过生产小试以及实际生产,可以满足100#真空泵油要求。
In accordance with the development of vacuum pump oil and the market requirements in recent years,on the basis of the current internal and foreign manufacture situation,the series products of mechanical vacuum pump oil which can meet the quality requirements are produced.
针对近几年真空泵油的发展及市场需求,根据国内外真空泵油生产情况,利用大庆高粘度指数石蜡基润滑油,经溶剂脱蜡等工序后作为真空泵油原料,生产出符合质量要求和客户满意的产品。
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.
用特定的原料油及工艺制成基础油，并添加评选出的粘度指数改进剂、抗乳化剂、抗氧化剂、防锈剂和减摩剂等凋合成耐水真空泵油。
