These fluids can also act as a sealant and, thanks to special additives,protect your hydraulic system from contaminationand damaging corrosion and wear.

市场上每种类型的液压油或液体都有不同的化学性质和粘度。因此,并非所有液压流体都与每个液压系统或应用兼容。了解不同液压液和油类型的特性以及如何选择粘度将防止损害,最终可能导致液压缸失效和昂贵的停机时间。

液压液和液压油是否相同?

尽管这些术语是互换使用的,但实际上它们可能意味着不同的事情。大多数液压液分为三类之一:合成,基于石油和水基。合成材料不包含任何实际的油,因此人们将其称为“液压液”。但是,矿物基液包含油。为了避免任何混乱,我们将在液压液类别下将所有内容都集结在一起,并且仅在引用特定油性液体时才使用“液压油”。

什么是不同类型的液压液?

合成液压液:合成是化学生产的液压液,含有添加剂以增强物理性能。优势因公式而异,但包括更高的工作温度,增强的润滑性,氧化稳定性,耐火性和生物降解性。一个缺点是合成材料比非合成方案更具毒性,并且可能损坏某些密封材料。

基于矿物质的液压油: These petroleum-based hydraulic fluids are derived from crude oil fractions and contain additives to improve viscosity, prevent rust and corrosion, and enhance heat resistance and wear resistance. Mineral-based hydraulic oils are popular because they cost less than synthetics but offer comparable performance.

多级液压油:这些高效率的油基液体含有添加剂以增强性能特性,但比合成材料便宜。一些多级液压油配方也包含染料,使其更容易identify fluid leaksin your hydraulic system.

水基液压油:这些液体不太常见,并且具有水 - 糖浆混合物,水中或油中的油乳液。高水含量使水基液压油具有耐火性,并且非常适合采矿等应用。

液压液粘度及其重要的原因

流体的粘度被定义为其对流和剪切的抗性。流体粘度有多个成绩,is the most important factor在您的液压系统的性能和效率中。实际上,粘度甚至是more比所使用的流体质量重要,应始终与系统的工作温度相匹配。

An important note is that fluid viscosity changes as temperatures fluctuate.太热或冷can make the fluid too thin or thick for your hydraulic system, leading to friction, wear, and sluggish performance. Operating your equipment under those conditions affects performance and can permanently damage your cylinders and hydraulic system. In short, choose your viscosity wisely!

液压油的易燃性和安全性

液压液和油都需要一些一般的安全预防措施,例如防止与皮肤,眼睛和口腔接触。一旦达到特定的温度或闪点,大多数液压油配方也是易燃的,这就是为什么它如此重要的原因avoid overheating your hydraulic system。在液体变化和维护过程中,总是戴着手套和保护性眼镜来保持安全。将液压液存储在点火源中,并在高温应用中使用耐​​火的液压液配方或有燃烧风险的地方。

记住,化学组成和物理改过的ies of each hydraulic fluid type vary by brand and fluid grade. Research fluid options thoroughly and read labels carefully before using a product in your hydraulic system. When in doubt, speak with a hydraulic system expert to get advice on choosing a hydraulic fluid for your mobile or industrial equipment.
