CDZ-Y1 Nitrogen Charging Vehicle works as a special N2 pressurizer

and charging device of hydraulic bag accumulator, piston accumulator,

diaphragm accumulator and other high pressure vessel of NXQ series.

Max N2 pressure is 42 MPa.

Model Note

CDZ – X(2.)– Y1(3)

(1)Code Name:N2 charging vehicle

(2)Nominal Pressure:25,35,42MPa

(3)Reversing type: Hydraulic Pilot

Operating Principle

The Nitrogen Charging Vehicle consists of hydraulic device, gas device and electric device. The pressure fluid flows into the pressurizer through reversal valve to push the piston move (or high-pressure vessel) through holding valve. N2 pressurized to the operating pressure by the reciprocating movement of piston. (Less than 42MPa)

Typical application

 1.Gas pressurization: charge or pressurize accumulator, aero tire, and high-pressure vessel, telecommunication cable with N2 or inert gases.

 2.pipe pressure test: N2 or inert gases in aerospace, oil field, refining, automobile, instruction.

3.Gas replenishment: chemical processes, plastic processes;

4.Gas Reuse: recover the gas or inert gas left in the nitrogen cylinder to high-pressure vessel for further usage.

5. Gas output and charging: N2, inert gases.
