if your talking about the hydraulic suspension ( "switches" ) i use 40 weight motor oil and never have any problems
Liquid is needed to use hydraulics. It's what makes hydraulics work.
Science of Hydraulics is the study of fluids, mostly liquids, in motion.
liquids are easier to move.
Hydraulics
Hydraulics are powered by liquids under pressure and pnuematics are powered by gasses, usually air, under pressure. Both liquids and gasses are fluids.
The incompressibility of most liquids.
Hydraulics is the use of liquids to transmit power. Pneumatics is the use of gases (usually air) to transmit power.
Hydraulics use liquids as the working fluid, pneumatics use gases as the working fluid.
The non-compressibility of liquids, and the equivalence of p = F/A (pressure equals force divided by area) explain why and how hydraulics work.
yes.only positive displacement pumps can be used in hydraulics
Yes, We have been using them for years on hydraulic pumps in our manufacturing facility.
People use it for their plumbing, the air brakes on trucks, hydraulics, etc.
