Page 5: Notes On Designated Application
Notes on designated application The Roth bladder accumulator (Roth pressure equipment) was manufactured exclusively for use as an industrial and commercial component designed for acceptance and delivery of pressurised hydraulic fluids in hydraulic systems. Any use of the pressure equipment other than or beyond as described above or any conversion by the operator or others shall be regarded as contrary to designated use, unless by prior written agreement of the manufacturer. -
Page 6: Function
Function General functional description Roth pressure equipments are cylindrical pressure vessels with a separating element between gas and fluid volumes (see Fig. 1-1). They are used in hydraulic systems among others for energy accumulator.If the fluid pressure rises above the gas filling pressure, hydraulic energy is stored in fluid form. This may be utilised for work steps when the fluid pressure falls below the pressure of the compressed gas. -
Page 7: 2.2.1 Isochore Behavior Of N2
2.2.1 Isochore behavior of N2 Determining or controlling the pre-filling pressure (P ) at different ambient temperatures General Unless otherwise specified, the given P refers to room temperatures of + 20°C. Should the actual ambient temperature be different at the time of filling or checking P , the diagram may be used to find the pressure corresponding to that temperature when filling or checking. -
Page 8: Safety
Safety Notes / Explanations Operating instruction, mandatory: marked with a “book”. Warnings: marked with a warning triangle “danger”. Explosion: marked with a warning triangle “explosion”. Notes: marked with a “hand”. Limitations: Marked with a “stop“ symbol. The vessel filled with N2 already, as given on the pressure equipment nameplate. Apply the separately included warning sign (scope of delivery) to the pressure equipment after final assembly/final coating. -

Page 13: Assembly / Commissioning
The operator of the system must be on receipt of the pressure equipment assume responsibility for storage in accordance with these instructions. Lengthy periods in transport or storage whilst packaged should be avoided. Assembly / Commissioning Setup / Installation The assembly if the pressure equipment is to be carried out by qualified staff and must be specially trained for this kind of work. -
Page 14: Maintenance
Repeated inspection §16 of the Occupational Safety Ordinance sets the schedule for routine testing (pay attention to the according national directives of the set-up country, see Chapter 3.5). Roth Hydraulics GmbH recommends the following periods: • External tests every 2 years •... -

Disturbance, causes, troubleshooting (qualified staff only) Disturbance Cause Troubleshooting • • Oil valve closed Open oil valve Pressure equipment will not supply hydraulic fluid • • Gas-side pressure too low Check pre-inflation pressure • • Pressure relief open Close pressure relief •... -
Page 16: Emergencies
Emergencies This pressure equipment is a passive system, without own drives. The stored energy will be charged or discharged by the connected active system of the operator. Emergency measures such as the operation of Emergency-Off systems or fast pressure relief action should therefore preferably be defined and documented in the work instructions of the operator. -
