(1)Do not use welding, crimping, or mechanical processing methods to fix the accumulator. (2) The accumulator must not be filled with oxygen or air. Nitrogen or other IW gas must be filled. (3) When storing energy, the inflation pressure should be lower than 90% (60-80%) of the minimum working pressure of the hydraulic system. (4) After the installation of the accumulator, the interface should be checked for air and oil leakage. (5) After setting the accumulator, the air pressure should be checked according to the specified period.
