Possible Trouble
For a piston accumulator, the seal ring is of great importance. If the piston is not properly installed during assembly process, the seal ring on the piston will be set at abnormal position, and it will be distorted or even broken into pieces when the accumulator works. As a result, oil or gas leakage will occur, leading to product failure.

Solutions
Under the above condition, the piston accumulator needs to be sent back to our factory. We will replace the damaged seal ring with a new one, and reinstall the accumulator strictly in accordance with the standard assembly procedure. After passing test that is carried out at higher oil pressure and gas pressure, technically speaking, two times of design values for both of them, the accumulator is allowed to leave the factory.
