Unfortunately applying hydraulics in real life isn't so simple.
are a few things to consider if you are planning on designing and building
Hydraulic System Analysis gave me some ideas on what to
The fluid to be used needs to have good lubricity, be chemically environmentally
stable, a favorable viscosity, compatible with the metals that are going
to be used, be readily available, low cost, foam, weight, etc. The fluid
used is usually a type of oil. Water is not used for a few reasons. It leaks
very easily (soaks into seals, gaskets), causes metals to rust.
A source of power needs to be chosen in cases where high pressure is needed,
basically a pump. The most popular types of pumps I found were gear, turbine
Hydraulic systems also include an accumulator (to store oil under pressure),
a reservoir (a place to put excess oil) and relieve valves. Other parts
include: pistons, rods, ports, snubber.
