Accumulator modules
The Bosch Rexroth AG Accumulator Modules, edition 2024-07, provide flexible installation options with configurations for 6, 8, and 10 accumulators in parallel, each with a 50-liter capacity, and single installations for 2 to 5 accumulators. They include options for manual or electric accumulator shut-off blocks and feature a glycerin-filled pressure gauge for maximum operating pressure. The modules are part of the component series 1X, with a maximum operating pressure of 330 bar.
The ordering code details the modular accumulator unit type (ABMAXX-MAU), standard (N), component series (1X), number of accumulators (2 to 10), installation type (single or parallel), pressure relief type (manual or electro-magnetic), individual shut-off presence, country acceptance, and seal material (NBR or FKM).
Designed for vertical installation in low corrosion industrial environments, the modules support a maximum operating pressure of 330 bar and a hydraulic fluid temperature range of +10 to +65°C. The cleanliness class for hydraulic fluid is ISO 4406 class 20/18/15. The frame is steel with a CP3 surface coating for non-corrosive environments.
- Single Installation: Available with 2 to 5 accumulators, featuring individual or overall shut-off options.
- Parallel Installation: Available with 6, 8, or 10 accumulators, with similar shut-off options.
Dimensions are provided for both single and parallel installations, with weights ranging from 413 kg to 2073 kg depending on the configuration.
The selection table provides detailed options for accumulator size, pressure rate, number of accumulators, installation type, shut-off options, and discharge pressure type, along with corresponding material numbers.
Accessories include mating connectors and cable sets for valves, with specific material numbers and data sheets provided.
Users must adhere to machinery documentation, legal regulations, and national pressure vessel regulations. Operating instructions are provided according to the accumulator's data sheet, with standard country acceptance executed according to CE.
The document outlines specifications for accumulator modules, which are assemblies under Directive 2014/68/EU. These modules must comply with safety standards according to DIN EN ISO 4413. Modifications void the operating license and warranty.
Installation and maintenance should be performed by authorized personnel only. The end-user is responsible for compliance with existing regulations. Repairs must be conducted by the manufacturer or authorized dealers to maintain approval.
Accumulator modules should operate within permissible limits. Warning signs must be visible and in the appropriate language. Systems with hydraulic accumulators require additional visible warning signs.
Before disassembly, pressure must be discharged. Only nitrogen should be used for filling. The warning sign should be clearly visible on or near the device.
Data sheets are available for various hydraulic fluids and components, including pressure relief valves and directional seat valves. Further details on spare parts can be found on the Bosch Rexroth website.
