To extend the service life of the accumulator bladder AB25/31.5-L-E, periodic inspection and maintenance are required. Generally, because the bladder is a rubber product, the service life is shorter. In case of damage, performance degradation and other abnormal conditions of the accumulator bladder, it is suggested to replace it in time to ensure the stability and safety of the hydraulic system.

Generally, the accumulator bladder AB25/31.5-L-E can be replaced under the following conditions:

• Damaged: when the accumulator leather bag is cracked, worn or deformed, the leather bag shall be replaced immediately to ensure the safe operation of the equipment.
• Performance reduced: when the inflation performance, sealing performance or pressure resistance of the accumulator bladder is significantly reduced, it indicates that the leather bag has been aging, and it is suggested to be replaced in time.
• Leakage: if the accumulator bladder has obvious leakage, such as oil stains, bubbles, etc., it indicates that the sealing performance of the bladder has been damaged and needs to be replaced.
• Beyond the service life: according to the operation instructions of the accumulator bladder, the bag has a certain service life. When the service life is reached, it is recommended to replace the bladder to ensure equipment performance.
• System fault: In the hydraulic system, if the system fault is found due to the damage or performance degradation of the bladder, such as unstable pressure and oil pressure drop, the accumulator bladder shall be replaced.
• Oil pollution: when the hydraulic oil contains a lot of impurities, which may cause wear or damage to the accumulator bladder, it is recommended to replace the bladder.
• High temperature and direct sunlight: the accumulator bladder exposed to high temperature and direct sunlight for a long time may be aged and degraded, affecting its performance. It is suggested to be replaced.
