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-A高真空油比M高真空油的使用温度范围更宽。
※ 产品抗磨性能明显提高,能降低泵浦压缩时的界面磨损。
※ 良好的泡沫特性,减少由于溢流、断流引起的真空泵磨损。
※ HFV-A高真空泵油使泵的使用寿命大大延长,使真空泵长时期保持高真空运转。
※ HFV-A high vacuum oil has wider temperature range compared to the M.
※ Better anti-wear ability to reduce interface wear when compressing.
※ Superior oxidation stability to effectively extend the oil-change intervals.
※ Desirable foam characteristics to reduce wear due to overflow and interruption of work fluid.
※ HFV-A high vacuum oil keeps pump running at high vacuum degree,with a much longer service life
※ HFV-A高真空油适用于较为苛刻的工况,在高温、高压强或高负载条件下仍能保持良好真空状态。
※ 可用于国内外各类机械真空泵,如英国Edwards、德国Leybold、法国Alcatel、日本Ulvoil等。
※ Applicable to poor working conditions and keeping good vacuum degree under conditions of high pressure or high loading.
※ Can be applied to various domestic and foreign vacuum pumps such as the British Edwards, German Leybold, French Alcatel and Japanese Ulvoil.
