Precautions when accumulating gas

Nitrogen is often required to be very slow when inflating bladder and diaphragm accumulators. If high-pressure nitrogen is allowed to expand rapidly as it enters the airbag, it will cause the polymer material of the airbag to cool to a point and immediately become brittle and fail. Fast inflation will also squeeze the airbag under the oil end cone valve, causing the airbag to be cut. If the pre-inflation pressure is too high or the minimum system pressure is reduced without a corresponding reduction in pre-inflation pressure, the operation of the accumulator will be affected and result in damage.

Excessive pre-inflation of the bladder-type accumulator can trap the bladder in the assembled conical valve when pressure is released, causing damage to the conical valve or the bladder. This is the basic cause of airbag failure.

Low pressure or no pre-inflation can also cause over-frequency fluctuations in the bladder-type accumulator. The result is that the airbag is wrinkled and damaged at the top of the housing under system pressure. This will cause the airbag to be squeezed in or punctured by the air valve. In this case, only one cycle is needed to destroy the airbag.

Similarly, too high or too low pre-inflation pressure will cause the piston of the piston accumulator to reach the bottom of the stroke end, damaging the piston and its seal. The good 万人炸金花 is that if this happens, an audible warning will be generated. That is, piston accumulators can be damaged by substandard inflation, they are still more tolerable than airbag accumulators.
