Hydraulic Accumulator Bladder

I. Product Introduction

NXQ series accumulator bladders are core internal components of bladder accumulators, isolating internal nitrogen gas from hydraulic medium to accomplish energy storage, pressure stabilization, and pressure buffering functions. This product features excellent material performance with oil resistance, acid/alkali resistance, folding resistance, high structural strength, and long service life. Manufactured in compliance with domestic HG/233192 industry standards and ASME international standards, it is compatible with various standard NXQ bladder accumulators for assembly and replacement, suitable for long-term cyclic operation in multi-industry hydraulic systems.

3. The company reserves the right to optimize product processes and structures; product updates will be made without separate notice to customers.

(II) Common FAQ

Q1: What is the difference between Type A and Type AB bladders?

A: The two have different structural lengths, suitable for different accumulator installation methods. Type A is for vertical conventional installation, Type AB is for horizontal and high-frequency vibration conditions.

Q2: Can a slightly leaking bladder be repaired and reused?

A: Rubber integrally vulcanized components cannot be repaired after damage and leakage; replacement with a new bladder of the same model is recommended.

Q3: Can the bladder be used with other brands of accumulators?

A: It is universally compatible if cylinder volume, length, and interface dimensions match; non-standard cylinders can be customized with dedicated bladders.

Q4: What are the storage requirements for bladders?

A: Store in a cool, dry, dark place, avoid compression, folding, and long-term contact with acid/alkali and oil contamination to delay rubber aging.
