Presses
are used in industries for a variety of uses like squeezing, forming
and pressing. There is various type of presses, the most famous two
being Hydraulic press and
Pneumatic press. They are used to perform some similar things.
However,
there are some differences between them, which need to be kept in
mind before choosing any one of them.
Pneumatic
Press
The
manipulation of pressurized air controls this press. The air is
forced into a tube, which after filling applies pressure on the press
to move it downwards. Once the stroke of the press gets completed,
the air is excavated through valves. Finally, mechanical spring’s
causes the pump to move upwards.
Hydraulic
Press
Hydraulic
presses are chambers filled with liquid, which is generally oil. A
piston presses into the chamber, causing the oil to shift position.
Since, the chamber is sealed the oil exerts pressure on large piston
or baseplate, causing it to move downwards.
Which
to choose Hydraulic or Pneumatic?
The
primary difference between the two is speed.
A pneumatic press is much faster than the hydraulic press, which
means
it can perform many jobs faster. However, this advantage is not
suited, where slow speed is required.
Level
of maintenance required is also different. Hydraulic presses require
more care and maintenance. They have many components which need to be
maintained regularly. This makes them more costly. On the contrary,
Pneumatic presses need less time and maintenance.
