Common Causes of Accumulator Pressure Damage

Accumulators are important components in hydraulic systems that store hydraulic energy, so their failure may have a negative impact on system performance. The following are some common reasons that may cause accumulator failure, including pressure loss:

Material fatigue: The material of the energy accumulator will be subjected to stress during the cyclic charging and discharging pressure process, which may lead to material fatigue. Over time, this can cause the diaphragm or wall of the accumulator to fail.

Pressure loss: Excessive or inappropriate working pressure may cause pressure loss of the accumulator. This may be caused by leaks, sealing issues, or other system issues. Pressure loss will reduce the performance of the accumulator and reduce its energy storage capacity.

Leakage: Over time, the seals of the accumulator may wear or age, leading to liquid or gas leakage. Leakage can cause pressure loss and reduce the efficiency of the accumulator.

External damage: The accumulator may be damaged by external environmental factors such as impact, vibration, or chemical exposure. These damages may damage the diaphragm or container, leading to accumulator failure.

Improper use: Improper operation or maintenance may cause the accumulator to fail. For example, excessive charging, frequent charging and discharging, or inappropriate temperature conditions may have adverse effects on the accumulator.

Sediments and pollutants: If solid particles or pollutants are present in the liquid, these substances may accumulate inside the accumulator and damage the diaphragm or seal.

Operating temperature issue: Excessive or low operating temperatures may affect the performance of the accumulator. Some accumulator designs are suitable for specific temperature ranges, exceeding this range may cause problems.

Extended use: Accumulators have a certain lifespan, and their performance may decrease over time. Periodic replacement and maintenance are crucial for extending the lifespan of accumulators.

Maintenance and regular inspection of hydraulic accumulators are key to ensuring their reliability and performance. Pressure loss is usually an indicator of accumulator problems, so it is important to regularly check and test the working pressure of the accumulator in the system. If problems are found, taking appropriate measures early can avoid more serious failures and ensure the safety and reliability of the system.
