The pressure drop of air bag accumulator is serious, and air replenishment is often needed. The inflation valve of the bladder of the airbag accumulator is in the form of one-way valve, which is sealed by the sealing cone.
When the accumulator is vibrated in the working process, it may loosen the valve core and make the sealing cone not close, resulting in air leakage. There is a groove on the conical surface of the valve core, or there is dirt on the conical surface, which may lead to air leakage.
At this time, a hard rubber pad with a thickness of about 3mm can be padded into the sealing cover of the inflation valve, and measures such as grinding the sealing cone to make it close can be taken.
The main reasons for the failure of the accumulator are serious air leakage of the air valve, no nitrogen in the leather bag and oil inlet due to the damage of the leather bag.
The solution is to check the air tightness of the air valve. In case of air leakage, strengthen the sealing and add nitrogen; If there is oil leakage at the air valve, it is likely that the skin bag is broken and should be replaced.
The effect of absorbing pressure pulsation is poor. In order to give better play to the absorption of pulsating pressure by the accumulator, the connecting pipe between the accumulator and the branch point of the main pipeline should be short, the diameter should be appropriately larger, and should be installed near the pulsation source. Otherwise, its effect of eliminating pressure pulsation is poor, and sometimes it will even aggravate pressure pulsation.
