Gas powered hydraulic power unit to be used for a period of time to carry out pressure relief, because: hydraulic power unit is generally with a check valve, and some equipment in the use of hydraulic power unit does not use the function of the power-off pressure relief, in this case if the equipment with an accumulator that is very dangerous, because the hydraulic power unit is very likely to hold the pressure of the situation.
The sudden release of accumulated pressure can produce a strong vibration and a loud noise. This can adversely affect the normal operation of the equipment. It may lead to the rupture of hydraulic components and fittings. As a result, the system might fail to continue working and could even cause personal safety accidents. So the purpose of pressure relief is to exclude the pressure in the pipeline and actuator.
Many gas powered hydraulic power unit is equipped with accumulators to supplement the leakage and maintain a constant pressure, absorb hydraulic shock, absorb pulsation and other functions, in order to protect the safety of the accumulator, must be installed pressure relief valve. When the pressure inside the vessel becomes too high, the pressure relief valve activates. It opens automatically to discharge the excess gas. This action helps protect the vessel from potential explosion.
