Perfluorohexanone fire extinguishing agent filling equipment

Perfluorohexanone fire extinguishing agent filling equipment

Product Overview:
  The perfluorohexanone fire extinguishing agent filling equipment is a professional device that combines efficiency, safety, and precision, suitable for the maintenance and installation of perfluorohexanone fire extinguishing systems. Equipped with nitrogen pressure reduction, a filling pressure alarm, a vacuum system, and a reserved interface for weight alarm nodes, the equipment supports a variety of gas cylinder sizes, ensuring airtightness and accuracy during the fire extinguishing agent filling process.

Equipment valve body function:
 

Heptafluoropropane filling operation:
1 After the cylinder is valved, move it to the filling room. Secure the cylinder and connect the piping between the cylinder and the filling station. Adjust the electric contact pressure gauge alarm and the pressure reducing valve outlet pressure. Open the cylinder container valve and slowly open nitrogen valve F2 to fill with nitrogen, controlling the pressure increase rate to no more than 1 MPa/min, until the pressure reaches the specified maximum operating pressure (see Appendix 3, "Test Pressure Comparison Table" for details). Close the cylinder container valve and move the cylinder to the pressure test room for a cylinder seal test.

2 After the cylinder seal test passes, move it to the filling room's platform scale. Secure the cylinder and connect the piping between the cylinder and the filling station. Open the cylinder container valve and open the pressure relief valve F4 on the filling station to relieve the pressure. After pressure relief is complete, pressurize the filling station vacuum button and simultaneously open vacuum valve F5. Start the vacuum pump to evacuate the cylinder. When the pressure gauge pointer approaches -0.09 MPa and stabilizes, close vacuum valve F5 and the vacuum pump in sequence. Vacuum control schedule:

3 Adjust the electric contact pressure gauge alarm and the pressure relief valve outlet pressure to 1 MPa. Then, sequentially open nitrogen valve F2 and filling valve F3 to fill the cylinder with nitrogen, displacing the gas in the cylinder. Slowly adjust the nitrogen pressure to 1 MPa. Once filling is complete, close nitrogen valve F2 and filling valve F3. Simultaneously, use a dew point meter to check the dew point of the gas in the cylinder and control it within 10 ppm. If the dew point is not within 10 ppm, re-evacuate and replace the gas with nitrogen until it is within 10 ppm before filling the agent.

4 Once the dew point in the cylinder meets the required dew point, open pressure relief valve F4. After pressure relief is complete, close pressure relief valve F4 and vacuumize the cylinder. After completion, close vacuum valve F5. First, subtract the weight of the cylinder from the scale and then set the desired weight of HFC-227ea fire extinguishing agent (according to the production order or planned requirements). Sequentially open HFC-227ea valve F1 and filling valve F3 on the filling station to fill the cylinder. Simultaneously, open the pressure gauge on the cylinder to relieve pressure. When the pressure gauge begins to release the extinguishing agent, stop relieving pressure and securely close the gauge. When the extinguishing agent reaches the set weight, the filling station will sound an overweight alarm, indicating completion and automatically shutting off the line. Then manually close HFC-227ea valve F1. During the filling process, maintain a rate of no more than 3 kg/s, with a filling volume tolerance of +0.5 to -0 kg (e.g., if the order requires 60 kg, control the filling volume to 60 to 60.5 kg).

5 Finally, perform nitrogen pressurization. First, adjust the pressure reducing valve outlet pressure to the HFC-227ea filling pressure under temperature conditions (refer to Appendix 2, "HFC-227ea Fire Extinguishing Agent Filling Temperature and Pressure"). Set the electric contact pressure gauge alarm. Then, slowly pressurize the cylinder. Open nitrogen valve F2 and filling valve F3 sequentially to increase pressure, controlling the pressurization rate to no more than 1 MPa/min. When the filling pressure reaches the specified pressure, close nitrogen valve F2 and filling valve F3. Simultaneously, close the cylinder container valve and open pressure relief valve F4 to relieve the pressure in the pipeline. After pressure relief is complete, remove the pipeline from the cylinder container valve, complete filling, and remove the cylinder.

6 After filling, allow the cylinder to rest for 1 hour. Verify the weight and pressure of the fire extinguishing agent in the cylinder. If there is no pressure or weight loss, move it to the semi-finished product area for storage. After storage for more than 24 hours, recheck the pressure before shipment. If the pressure is too low, re-pressurize to meet the corresponding pressure requirements. 3.7 If the pressure in the HFC-227ea tank is not enough to allow the agent to be discharged, the tank needs to be pressurized, and the added pressure shall not exceed 2MPa.
