Hydraulic accumulator refilling

We have started a new service - Hydraulic Accumulator Refilling
 
Hydraulic accumulators are used to accumulate energy in a closed encased space in a hydraulic system. A working liquid (oil) is practically incompressible and is not a suitable medium for accumulation of energy. Gases, however, have a far higher compressibility. There are two units separated with a sealing diaphragm made out of gum present in the accumulator. A neutral gas is injected through a valve and compressed until reaching the so called pre-charging pressure. On the other side of the accumulator there is a hydraulic port connecting the valve with the system. When the oil pressure exceeds the pre-charging pressure the oil will start flowing into the hydraulic accumulator. While the working liquid pressure keeps on rising, the separator starts shrinking causing the gas pressure to reach the same level, and its volume to decrease, thus allowing the further inflow of the oil.
 
Application:

  • accumulation of compressed oil,
  • suppression of pressure pulsation and flow disturbances,
  • increase in effectiveness of the system,
  • power supply in case of emergency,
  • absorption of pressure pulses,
  • suggested for hydraulic systems requiring high oil intake in short amounts of time (e.g. hydraulic hammers).
