LSE series accumulator capsule

LSE series accumulator capsule

The LSE series accumulator capsule (also known as a bladder or bag) is a critical component in hydropneumatic bladder-type accumulators, used primarily for pressure management and energy storage in hydraulic systems.

Key Characteristics of LSE series accumulator capsule: 

• Pressure Separation: Divides the accumulator into two chambers—one for pressurized gas (typically nitrogen) and one for hydraulic fluid.

• Gas Tightness: Designed with high-integrity sealing (often dual-pillar) to prevent gas leakage into the hydraulic fluid.

• Rapid Response: Offers extremely quick response times compared to piston accumulators, making it ideal for high-frequency applications.

• Durability: Typically features a long design life (up to 20 years in specific floating conditions) and a wide operating temperature range (e.g., -15°C to 55°C).

• Fluid Compatibility: Highly tolerant of fluid contamination and works well with low-lubricity fluids like water.

Application: 

• Shock Absorption & Pulsation Dampening: Absorbs hydraulic energy impacts and reduces pressure spikes caused by pump cycling or valve movements.

• Energy Storage: Acts as an emergency power source to operate critical components (e.g., brakes or safety shut-offs) if the main pump fails.

• Pressure Maintenance: Compensates for internal or external leakage in closed circuits to maintain system stability.

• Thermal Expansion Control: Manages fluid volume changes caused by temperature fluctuations to prevent system over-pressurization.

• Supplemental Flow: Assists the hydraulic pump during periods of peak demand to maintain consistent pressure and flow.

Packaging & Delivery

Accumulators are typically packaged securely to prevent damage during transit. The packaging includes:

Protective Wrapping: To safeguard the pump from environmental damage.

Custom Crates: For larger, heavier pumps, ensuring safe handling.

Documentation: Includes installation, maintenance instructions, and warranty details.

Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.

Certifications & Quality Assurance

All hydraulic accumulators are manufactured in compliance with international standards, ensuring high performance and reliability:

ISO 9001: Certified for quality management systems.

CE Certification: Ensures compliance with European safety, health, and environmental protection standards.

RoHS Compliance: Ensures the pump does not contain hazardous materials.

Factory Testing: Every pump is rigorously tested for performance, pressure, and leak integrity before shipping.
