Hydraulic Accumulatorswith Back-Up Nitrogen Bottles1.GENERALTo complete the accumulator range,HYDAC provides a variety of usefulaccessory products. They guaranteecorrect installation and optimumfunctioning of HYDAC hydraulicaccumulators. They include nitrogenbottles which can be used to back upbladder and piston accumulators. Nitrogenbottles used as back-ups increase the gasvolume in the accumulator. This meansthat smaller accumulators can be used forthe same gas volume and costs can bereduced.2.BACK-UP VERSIONS2.1. SET-UP USING THE EXAMPLE OF A BLADDER ACCUMULATORBased on bladder accumulator models 20 . 50 l, the gas-side of these accumulators isdesigned especially for connecting to nitrogen bottles. A diffuser rod prevents damageto the bladder when the accumulator is charged. This design can also be used forthe separation of fluids (taking into account the volume ratios which apply to bladderaccumulators).Type 1Adapte FPSPipingFor further information, please turn to thesections:zzBladder AccumulatorsStandardNo. 3.201zzPiston AccumulatorsStandardNo. 3.301HydraulicaccumulatorNitrogen bottleOil valveAdapterAdapter FPSPipingEN 3.553.5/06.18Type 2103
