If liquid is not compressible, why do we need special hydraulic fluid? Why not just use water?
In: Engineering
Water also boils at comparatively low temperatures/pressures. I’m sure there’s something relevant about phase transitions in hydraulic systems that makes the behaviour of oils more stable/predictable.
Minor benefits are also that it doesn’t freeze (as soon) and doesn’t explode into a gas if a line breaks – it’ll still spray highly toxic, high speed, terribly hot oil everywhere but it won’t be as much of an explosion. I think.
