2. What is a Hydraulic press
▪ a machine in which great force with slow motion
is communicated to a large plunger by means of
liquid force into the cylinder in which it
moves by a piston pump of small diameter to
which the power is applied.
3. What is the principle of Hydraulic Press?
Hydraulic press works on the pascal’s law.
Pascal’s law statement: in a fluid at rest in
a closed container, a pressure change in one
part is transmitted without loss to every
portion of the fluid and to the walls of the
container.
5. How does a hydraulic press work? Pascal's Law in action
▪ A piston is inserted into the cylinder B and
pressure is applied. The pressure applied
causes the fluid to move through a pipe and
into a larger cylinder. The larger cylinder a
is known as the master cylinder. The pressure
exerted on the master cylinder and the piston
in the master cylinder pushes the fluid back to
the slave cylinder. The force applied on the
fluid by the slave cylinder results in a large
force, which is experienced by the master
cylinder. An industrial hydraulic press comes
along with what is known as the press plates.
With the help of these press plates, the
material to be worked on is either punched or
crushed into sheets.
