GMDX-A Nitrogen Gas Automatic Filling Machine

Nitrogen gas filling machine can be used for vast fire apparatus production and maintenance manufacturers to fill nitrogen to steel cylinder that needed to be pressurized by nitrogen gas.

The filling machine is built in a constant pressure controlled filling system. With advantages such as safe and reliable, easy to operate, high efficiency and high precision of charging pressure.

Maintenance Notice :

1. The filling equipment must be maintained by qualified person and be inspected periodically;

2. The filling equipment must be installed in dry and ventilating site;

3. If the power cannot be switch on, open the back door of the cabinet and check for tripping of the leakage circuit breaker. If it has tripped, use mega meter to check whether 220V power lead insulation resistance to the casing is less than 10M Omega or not, and find the trouble position and clear the trouble before continuing filling;

4. Because the gas pressure in the pipeline is very high, if any leakage is found, tighten the joint of the pipeline immediately and make sealing treatment.

GMDX-A Nitrogen Charger and Integrated Extinguisher Pressure Calibrator

1.General:

GMD-A nitrogen filling machine(hereinafter referred to as filling machine) can be used for vast fire apparatus production and maintenance 

manufacturers to fill nitrogen to steel cylinder that needed to be pressureized by nitrogen gas.For example:

after dry powder fire extinguisher is filled with dry powder,it must be pressurized using inert gas nitrogen and 

when extinguishing fire using dry powder fire extinguisher,the dry powder will be sprayed out towards the flame 

together with the high pressure nitrogen and extinguish the fire quickly.

This filling machine is built in a constant pressure controlled filling system.With advantages such as safe and 

reliable,easy to operate,high efficiency and high precision of charging pressure etc.,it is the ideal filling 

equipment for fire apparatus production and maintenance manufacturers at present.

Specifications:

Volume:510x550x1030mm;

Weight:31kg;

Power Source: AC220V±5%;

Filling Gas Pressure Control Range: 0.1MPa~2.5MPa adjustable

3.Direction for Use:

 1.Switch on the power switch with the key,lighting of the power indicator means the main power source of the 

   equipment has been switched on.

2.Connect the air inlet at the side of the cabinet to the nitrogen steel cylinder using pressure resistant copper 

   tube,open the air source switch after screwing down the leather hose clam screw,then observe the air inlet 

   pressure gaugeon the panel and adjust the pressure reducing valve on air supply steel cylinder to adjust 

   the air inlet pressure to the specified value(e.g.2.5MPa).

3.Based on the data of the pressure needed in the steel cylinder to be filled,adjust the pressure arm   (rising/close) set in the electrical contact pressure gauge to specified value using screwdriver(e.g.1.5MPa).

4.Connect the charging pipe to the steel cylinder to be filed and screw down,then press"charging" switch.The 

 electromagnetic valve opens,the "charging indicator" lights,the gas enters into the steel cylinder and the pointer

 of the electrical contact pressure gauge moves slowly.When the point moves to the set position (e.g.1.5MPa),the electromagnetic valve will close automatically and the charging indicator will extinguish.

5.When filling is completed,unscrew the charging pipe clam and change to another steel cylinder to be filled,

continuous filling is permitted.After the work is finished,switch off the main power using the key,and screw down 

the pressure reducing valve on the nitrogen source steel cylinder simultaneously.

4.Maintenance Notice:

1.The filling equipment must be maintained by qualified personnel and be inspected periodically.

2.The filling equipment must be installed in dry and ventilating site.

3.If the power can't be switched on,open the back door of the cabinet and check for tripping of the leakage 

circuit breaker.If it has tripped,use mega meter to check whether 220V power lead's insulation resistance to the 

casing is less than 10MΩ or not,and find the trouble position and clear the trouble before continuing filling.

4.Because the gas pressure in the pipeline is very high,if any leakage is found,tighten the joint of the pipeline 

immediately and make sealing treatment.
