惠丰企业生产的真空油采用优质的基础油和进口添加剂调配而成,是一种理想的润滑材料,广泛应用于我国军工企业、显示行业、照明行业、太阳能行业、镀膜行业、制冷行业、航空航天等。
※ HFV-M高真空油具有精致程度深,芳烃和胶质含量少的优势。
※ 粘度指数高,闪点高,在较高温度状态下真空不易下跌。
※ 遇水蒸气不易乳化,油水分离性极强。
※ 较好的氧化安定性,降低油垢和结焦的产生,减少泵油更换次数。
※ Fine purification, small amount of aromatic and gum.
※ High flash point and viscosity index to keep stabilization of vacuum degree at high temperature.
※ Superior ability of emulsion resistance and oil-water separation when exposed to water vapor.
※ Good oxidation stability,inhibition of grease stain and coking and extending the oil-change intervals.
※ M高真空油适用于国内外各类机械真空泵。
※ Ml00适用于4L以下直联旋片泵及罗茨泵,在制冷行业中抽水量较大的场合尤为合适。
※ M200适用于5L~30L直联旋片泵及罗茨泵,其适于显像管、照明行业中使用。
※ M250适用于30L以上直联旋片泵及罗茨泵在制冷、电真空、冷冻干燥、蒸馏、生物、化学工程等行业中使用。
※ HFV-M is applicable to various domestic and foreign mechanical vacuum pumps.
※ HFV-M100 is suitable for vane rotary vacuum pump and roots pump with volume flow rate of 4 Liter,esp.for refrigerating industry with large pumping.
※ HFV-M200 can be applied to vane rotary pump with volume flow rate from 5 Liters to 30Liters,esp.in picture tube and illuminating industry.
※ HFV-M250 is suitable for vane rotary vacuum pump and roots pump with volume flow over 30 Liters. Applicable to industries such as refrigeration, electronic-vacuum, distilling, , biology, chemical, etc.
