真空泵油的理化指標(biāo)

真空泵的真空度一般為10-4最高要求可到10-8毫米汞柱甚至以上，所以真空泵油的質(zhì)量重點(diǎn)是應(yīng)具有極低的蒸氣壓。也即要求潤滑油的蒸發(fā)性極小，數(shù)石蠟基窄餾份潤滑油較為理想。又因真空泵容易吸入水分所以潤滑油應(yīng)具極好的水分離性。對于用于抽氣的，含雜質(zhì)和污物的真空泵，潤滑油還需含有清凈、浮游性添加劑，以防止在真空泵潤滑部位產(chǎn)生油泥、積炭及污垢。

理想的真空泵油應(yīng)具有高的粘度指數(shù)、低的飽和蒸汽壓、好的油水分離性和氧化安定性，好的抽氣速率和極限真空。真空泵油的理化性能檢測項目有：運(yùn)動粘度（40℃）、粘度指數(shù)、閃點(diǎn)、抗乳化度、抗泡性、氧化安定性、飽和蒸汽壓、極限全壓力和極限分壓力。根據(jù)質(zhì)量等級設(shè)定的各項理化性能檢測項目的質(zhì)量指標(biāo)可查見于石油產(chǎn)品行業(yè)標(biāo)準(zhǔn)sh/t0528-92。
