Precautions for carbon dioxide fire extinguisher filling machine

Maintenance and maintenance

1.During use, check whether the fasteners at each joint are loose at any time, and tighten them immediately if they are loose.

2.After each shift is stopped or when it is not in use for a long time, the remaining air in the pipeline and pump should be cleaned.

3.The cylinder where CO2 is stored should be kept clean and free of dirt to prevent clogging of the valve port.

Precautions

1. This equipment must have good protective wiring.

2. All electrical appliances and circuits of this equipment shall not be injected with water and other debris.

3. The filling machine should be installed in a dry, ventilated, clean and flat work site.

4. The equipment should be used at the rated voltage, otherwise it will cause failure.

5. Do not pry or hit with heavy objects arbitrarily inside the weighing platform, and do not rotate the bolts to prevent changing the limit gap. The weighing platform should be leveled before use (overloading is strictly prohibited).

6. Metal high-pressure hoses cannot be twisted forcefully or the bending radius of the pipeline is too small.

7. The power cord should be cut off after the equipment is turned off or after get off work, and the remaining air in the pipeline should be cleaned.

8. For units that use carbon dioxide filling equipment, five requirements and five requirements must be met.

9. After the filling of the fire extinguisher is completed, the pressure of the bottle valve must be loosened before the A joint of the filling pipe can be unscrewed, otherwise it will easily cause dangerous accidents.

10. When connecting the pipeline, be sure to connect and tighten it according to the signs pasted on the pipeline, otherwise it will easily damage the pipe joint.

For units that use carbon dioxide filling equipment, five requirements and five requirements must be met.

Five essentials: (1) Only units with permits issued by the competent fire protection department at a higher level can repair and produce.

(2) There must be rules and regulations of the quality assurance system and operating processes that meet national standards in order to maintain production.

(3) Only fixed operators who have undergone special training, are serious and responsible for their work, and hold induction certificates can maintain production.

(4) There must be a production site with good ventilation, cleanliness and width (greater than 20m2) in order to maintain production.

(5) There must be a safety protective barrier. The strength of the barrier between the operator and the equipment must be greater than the strength equivalent to 120mm thick reinforced concrete, and the height must be higher than the height of the operator by more than 300mm.

Five do not: (1) Do not use fire extinguishers that have not been hydrostatic tested in accordance with GB4399-84 for filling.

(2) Do not use equipment without a good safety grounding device, and fire extinguishing agent cylinders without safety devices for filling.

(3) Do not use equipment that has not been inspected in all directions for consoles, instruments, pipes, fixtures, and weighing instruments when you are on duty for filling.

(4) Do not use cylinders, valves, electrician straws, and fuse accessories that do not meet relevant national standards for filling.

(5) Do not use weighing instruments, instruments, and equipment that have not been inspected within the time limit for filling.
