 Operating Principle

The Nitrogen Charging Vehicle consists of hydraulic system, gas system and electric system. The pressure fluid flows into the pressure cylinder through solenoid directional valve to push the piston move upward(downward) to pressurize the N2 in the pressure cylinder and then flow into the accumulator(or high-pressure Vessel) through holding valve and charging tool. N2 is pressurized to the operating pressure by the reciprocating movement of piston under the effect of limit switch. After that, it stands on its own.
