Updating Old Accumulator Systems

Customer Requirements

Torishima Fluid Power were called into solve a problem with an old weighted type accumulator used for pressurising a series of presses using water.

Torishima Solutions

Our two specialist areas of Accumulator Technology and Water Hydraulics were called upon to solve the problem. We supplied a complete design to commissioning service.

New weighted type accumulators are now obsolete so the choice was between bladder and piston accumulators. The cost of piston accumulators was too much for our customer's budget. We then calculated that four off 50 litre bladder accumulators with 50 litre back up bottles wre required to meet the duty cycle of the system. The accumulators were lined and had stainless steel fluid ports and accumulator charging valves. The new accumulator system replaced two existing systems and we installed water hydraulic pressure reducing valves to supply two different pressures to the presses. 

We also installed the new accumulator system, connecting to the existing pump and press system with a mixture of stainless steel pipe and hoses with stainless steel ends. The complete system was fully commissioned.

Customer Benefits

  • Expertise in water hydraulics and accumulators helped solve a difficult problem at a relatively low cost.
  • Complete service from design to commissioning, reducing the risk of problems and lowering the cost.
  • Reduced system size, reduces the maintenance requirements of the system.
