Common Failure cause of accumulators and solutions

  1. Damaged nitrogen diaphragm

The damage of the nitrogen diaphragm often makes it difficult for the accumulator to bear the buffering and vibration reduction effects. When checking the accumulator, you can slightly press down on the detection pin on the detection valve by hand. If it can be easily pressed down, it means there is no nitrogen gas and it is likely that the diaphragm is damaged. The solution is to replace the diaphragm and apply silicone grease on the edges to provide a sealing effect.

  1. Damaged O-ring seal

The O-ring is usually made of rubber, so it is prone to aging and failure after long-term use. At this time, the nitrogen pressure of the accumulator drops quickly or there is oil leakage at the sealing ring. At this point, simply replace the sealing ring and tighten the nut of the detection valve to solve the problem.

  1. Damaged intake valve

Before using the accumulator, loosen the intake valve nut every time nitrogen is charged, which may cause damage to the intake valve over time, leading to slow or ineffective inflation. The solution is to replace the intake valve nut.

  1. Accumulator cracks

If the accumulator is often operated under harsh conditions, it is easy to cause cracks on the surface and may result in oil or gas leakage. If the crack is not large, special glue can be used to plug it. If the crack is large, it can only be handed over to professional maintenance personnel for treatment.
