Accumulators – integrating different functions in one piece

The accumulator integrate various functions into one part. The hydraulic bladder accumulator covers the top performances on the test stand, which thus can be higher than installed on the unit. A low pressure accumulator also mutes the pulse locations in the return line. Important safety functions are also integrated into the block. The connection of the pressure is controlled by two series-large valves, the position of which is electrically monitored over.

On the front panel connectors are for the drives. In addition to pressure and return line also leaked oil-connections have this available. On request, the accumulators can be supplied with soft-start functions. The number of terminals and the size is scalable.

Main features:

  • safety function
  • overpressure protection
  • memory connector
  • soft switch-on
  • pressure decrease
  • flow limitation for setup mode
