真空泵油有哪些分类特点 真空泵油有有什么应用领域

一、真空泵油分类特点: 

  (1)闪点也是真空泵油较显要质量指数的一。它不仅是从易燃安全性能方面考虑。而是闪点高往往轻质组分油含量较少。因此当油温上升时,轻沸点油分子不易挥发,能有效地保持极限压力。

   (2)抗泡性,运转中真空系统内气体会通过密封真空泵油层不断排出,排出气体会在油层表面产生大量气泡,并从泵排气孔中溢出,造成油品损失与设备污染。加防抗泡剂泵油,在抗泡效果上有明显提升。

二、真空泵油有什么类别

        真空泵油是一种专门为真空设备上的真空泵而研制的润滑油,分矿物油和合成油两种。 

三、原理特征: 

        

氧化稳定性:长期在高温条件下与空气、树脂、化学原料等直接接触亦不易变质,减少有害漆膜和油垢的形成,提供较长的换油周期。

防锈防腐蚀性:能在金属表面形成非常有效的防腐膜,从而可以全面防止因吸入腐蚀性气体和水分而导致的系统腐蚀。

能迅速将油液中夹带的水分分离出来,达到所需的真空度。

具较底的蒸汽压,防止油品从泵的内腔向真空系统返流扩散造成返油。从而保证有足够的极限真空。

四、应用领域:真空泵油适用于往复式增压泵、机械增压泵和油封机械真空泵等使用,亦可用于各种扩散真空泵等。推荐用于工艺品、陶瓷、化学等领域的真空泵使用
