1Overview diaphragm accumulator type AC
Diaphragm accumulator are a type of hydraulic accumulator. A diaphragm
eparate the compre ible ga cu hion from the hydraulic uid.
The diaphragm accumulator type AC i u ed a a ource of pre urized oil. It
upport or increa e the pump delivery ow or tore pre ure energy, e.g. for an
accumulator charge circuit.
With the aid of different tting the hydraulic accumulator type AC can be integrat-
ed into a hydraulic y tem. Different in tallation orientation and in tallation
po ition are po ible.
Features and benets:
■Compact de ign
■Option of integration into the HAWE modular y tem
■Operating pre ure up to 350 bar
Intended applications:
■Clamping y tem
■Jig
■Accumulator charging y tem
These accumulators are used to:
■tore pre ure energy
■upport the pump delivery
■improve y tem efficiency
■pul ation dampening in hydraulic y tem
■compen ation of pre ure variation due to temperature change
■compen ate internal leakage (when apparent)
