GTM-D type carbon dioxide filling machine instruction manual

I. Overview

    GTM-D type CO2 filling machine is a new product developed and produced by researchers in our factory with reference to the advanced technology and advantages of CO2 filling machines at home and abroad, combined with the characteristics of bottled CO2 as a gas-liquid mixture.Because it is a liquid conversion between a closed pipeline and a container, it is fast and efficient in filling, and it is an ideal replacement equipment for traditional CO2 filling machines.This machine has the characteristics of compact structure, stable operation, energy saving, accurate filling, small size, small footprint, and wide range of uses. It is the ideal equipment of choice for manufacturers of CO2 fire extinguishers for production and maintenance.

3. Description of the operation process

1. Equipment placement and stability: Before the equipment is used, the equipment should be placed in sequence according to actual needs. All parts of the equipment should be placed on the horizontal ground and placed smoothly.This equipment consists of three parts: a weighing table, a filling machine, and an air source cylinder bracket.Among them, the filling machine is composed of a motor, a CO2 high-pressure pump, a pressure sensor, a weighing table, a safety valve, a high-pressure ball valve and a matching high-pressure pipeline.After the weighing platform is placed, the casters should be adjusted to make it place smoothly; after the filling machine part is placed, the casters should be put on the brakes so that it cannot be moved at will; after the air source cylinder bracket is placed on the horizontal ground, it should be adjusted so that it should not shake at will. It is appropriate.

2. Wiring: Before turning on the power, connect the power cord and connect the ground wire, connect the filling machine line to the weighing table (just plug the plug into the weighing table), turn on the power supply, turn on the power switch, the meter is on, indicating that the power supply is normal, press the filling start button, the motor can drive the high-pressure pump to work, press the filling stop button, the high-pressure pump stops working.

3. Pipeline connection: connect the A joint on the filling pipe (Figure 2) to the CO2 gas source cylinder on the bracket, and the B joint at the other end of the conveying pipe (Figure 2) to the air inlet of the high-pressure pump; then connect the air outlet of the filling machine to the B joint of another filling pipe (Figure 2), and connect the A joint of this filling pipe (Figure 2) to the bottle valve of the fire extinguisher to be filled.After the connected pipeline is checked for accuracy in all directions as required, the fire extinguisher is placed on the weighing table and ready to be filled with CO2.

4. Filling of fire extinguishers: First, after connecting the pipelines, close the manual ball valve (Figure 2) connected to the fire extinguisher valve pipeline, put the fire extinguisher on the weighing table, turn on the power switch, and set the system pressure gauge to 12 MPa (If the system pressure exceeds 12Mpa, the high-pressure pump stops running.The pressure has been set at the factory, and the user does not need to set it again. If you need to reset it, you can refer to the instrument setting method on the next page), after the weighing display instrument is cleared to zero, then set the weight of the CO2 to be filled, and then open the CO2 cylinder valve, observe the system pressure gauge indicator, when the system pressure gauge no longer changes, the pressure in the pipeline reaches equilibrium, then press down the CO2 cylinder valve and fix it, turn on the control switch, the high-pressure pump starts to work, CO2 is sucked and discharged through the high-pressure pump in the filling machine, and the CO2 is transported from the outlet of the pump to the waiting Put in a fire extinguisher.During the first filling, because there is air or CO2 gas in the tube, it is easy to cause gasification when the high-pressure pump is running, so it needs to be deflated until the liquid is discharged before the filling can be started.After the filling weight is reached, the CO2 pump immediately stops working, closes the manual ball valve connected to the fire extinguisher bottle valve (Figure 2), then releases the handle of the fire extinguisher bottle valve to close it, and finally loosens and removes the A joint of the filling pipe connected to the fire extinguisher (Figure 2), and then removes the filled fire extinguisher to complete the filling work.
