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-AS高温、高负荷高真空油比A高真空油的使用温度范围更宽,粘温性能更好。
※ 优异的氧化安定性,热稳定性,在高温状态下能长时间保持高真空运转。
※ 良好的泡沫特性,减少由于溢流、断流引起的真空泵磨损。
※ HFV-AS高温、高负荷高真空油使泵的使用寿命大大延长,减少换油次数。
※ HFV-AS oil has wider temperature range compared to the A.
※ Excellent oxidation stability and thermal stability to keep a high vacuum running for a long time at high temperature.
※ Desirable foam characteristics to reduce wear due to overflow and interruption of work fluid.
※ HFV-AS oil keeps pump running at high vacuum degree,with a much longer service life.
※ HFV-AS高温、高负荷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 load.
※ Can be applied to various domestic and foreign vacuum pumps such as the British Edwards,German Leybold,French Alcatel and Japanese Ulvoil.
