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-BS为高温、高负荷、高真空油。
※ 极佳的抗磨润滑性能,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-BS高温、高负荷高真空油使真空泵长时间保持高真空运转,极大地减少换油次数,延长泵的使用寿命。
※ HFV-BS high vacuum oil belongs to high temperature,high load and high vacuum.
※ Excellent anti-wear ability to reduce interface wear when compressing.
※ Desirable foam characteristics to reduce wear due to overflow and interruption of work fluid.
※ HFV-B high vacuum oil maintain the pump a high vacuum operation in a long time, effectively reducing the number of oil changes, extending the life of the pump.
※ HFV-BS高温、高负荷真空泵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 load.
※ Can be applied to various domestic and foreign vacuum pumps such as the British Edwards,German Leybold,French Alcatel and Japanese Ulvoil.
