PLC Control Gas Filling Machine with Two Workstations

( Model code: DLS-D25C-2 )

Suncenter DLS-D25C-2 model gas filling machine adopts compressed air as power source, and the built-in pneumatic booster pump automatically reciprocates and pressurizes in proportion to drive the medium gas to be transported and filled in high-pressure liquid state, which greatly improves the filling speed. Moreover, the machine adopts automatic pressure control and weight control to realize filling automation and improve filling efficiency and filling weight accuracy. The machine is especially suitable for filling liquid CO2, N2O, Freon and other media.

Main Components 

This system fixes and seals gas cylinder by clamping the cylinder, and adopts Suncenter DGD25-C customized booster pump to fill, electronic scale automatically measures, automatically pauses filling when reaching the preset weight, and releases the gas cylinder automatically. The machine adopts automatic pressure control and weight control to realize filling automation and improve filling efficiency and filling weight accuracy. 

Technical Parameters 

Connection Ports

Gas inlet port: connect to CO2 / N2O gas cylinder by hose

Driven air inlet port: connect to air compressor

Electric control panel

Operation Steps 

1. Connect air-compressor and CO2 cylinder to the relevant ports on the machine’s right side. Adjust the driving air regulator to around 0.6MPa. 

2. Power on the machine, . 

3. Preset filling pressure range on Digital gauge. 

The pressure value must be lower than Nominal working pressure of your cylinder.

4. Preset gas filling weight on Filling weight controller

5. Place empty gas cylinder on workstation, press Start button, the workstation will clamp the cylinder, then machine starts filling gas. 

6. When the preset filling weight is reached, the machine stops filling, and buzzer on, then the workstation will release cylinder automatically, gas filling job completed. 

Remark: 

The machine is equipped with 2 workstations, each workstation has an independent control unit, which can complete 2 filling tasks at the same time.
