描述
通常人們憑經(jīng)驗(yàn)認(rèn)為“粘”度越“粘”真空度越好。其實(shí)并不如此,“稀”與“粘”是相對(duì)目測(cè)與手感而已,并沒有定量數(shù)據(jù)。如在40℃時(shí)測(cè)出兩僅僅油品粘度值相同話,當(dāng)油品冷卻到室溫下,其中“稀”要比“粘”油好。因?yàn)椤跋 庇驼扯戎笖?shù)要比”粘”高。粘油隨溫度變化而粘度變化也大,也就是粘度指數(shù)低,粘度指數(shù)是真空泵油顯要指數(shù)。粘度指數(shù)高泵油其粘度及溫度的間變化較少。而且冷泵運(yùn)行輕松,有顯著節(jié)約消耗用處,特別在夏季,隨著環(huán)境溫度與泵內(nèi)油溫上升,該油極限壓力能保持良好效果。
