PRINCIPLE:
Oil
pressure is intensified due to the area ratio of air piston &
oil piston. As the air
piston moves
towards the end position, pressurized
air input is diverted & is used for pilot operated pneumatic
direction control valve. Due to this arrangement, air piston is
reversed at both ends. Hence this system is self-reciprocating
& acts as pump. Two check valves are used in suction &
delivery line.
OPERATION:
Clean &
lubricated air is connected to "Hy-Power" air driven
pump. Pump reciprocates to give oil output till full pressure
is reached. By changing hydraulic direction control valve position,
pump reciprocates to operate cylinder till full pressure is reached.
In case of oil leakage & pressure drop, pump operates to compensate
the pressure drop.
ADVANTAGES:
Pressure holding
without consuming power. No heat builds up. Adjustable oil output
flow & pressure. Can be driven by any inert gas. Built in
tank & Optional CETOP 3 interface.
APPLICATIONS:
"Hy
Power" air driven pump is a
good replacement to electric power unit. It is more suitable for
clamping / holding application. E.g. Job clamping by double acting
elements in fixtures. Die clamping cylinders & die lifters.
