Technical requirements for diaphragm accumulator

Here are the technical requirements for a diaphragm accumulator:

  1. Pressure Rating: The diaphragm accumulator should be designed to withstand the maximum pressure anticipated in the hydraulic system without failure. This pressure rating is typically specified in bars or PSI.
  2. Volume Capacity: It must possess adequate volume capacity to store the required amount of hydraulic fluid at the specified pressure levels. Volume capacity is generally measured in liters or gallons.
  3. Diaphragm Material: The material used for the diaphragm should be compatible with the hydraulic fluid and capable of withstanding the operating pressures and temperatures. Common materials include elastomers such as nitrile rubber, EPDM, or fluorocarbon rubber (Viton).
  4. Sealing System: A reliable sealing system is essential for maintaining pressure integrity and preventing fluid leakage. The seals and diaphragm should be compatible with the hydraulic fluid and resilient to the system’s operating conditions.
  5. Mounting and Installation: Proper mounting and installation are crucial for safe and efficient operation. The accumulator should be securely mounted within the hydraulic system, ensuring correct alignment and accessibility for maintenance.
  6. Safety Features: Incorporating safety features such as pressure relief valves or rupture discs is critical to prevent over-pressurization and ensure fail-safe operation during emergencies.
  7. Maintenance Requirements: The design should allow for easy inspection, maintenance, and replacement of components such as the diaphragm and seals. Clear maintenance procedures should be provided to ensure reliability.

Meeting these technical requirements ensures that the diaphragm accumulator functions effectively within the hydraulic system, providing reliable fluid storage and pressure regulation while maintaining safety and compliance with industry standards.
