Heptafluoropropane (HFC-227ea) is a commonly used gas fire extinguishing agent, widely used in gas fire extinguishing systems, especially in sensitive environments such as computer rooms, data centers, and archives. The chemical filling of heptafluoropropane fire extinguishing system is a highly technical task that requires strict adherence to standard procedures to ensure the effectiveness and safety of the fire extinguishing agent.
The heptafluoropropane drug filling system can be achieved by driving it with a gas booster pump. The filling process is accomplished by vacuuming and filling the drug with nitrogen gas. The main components of the gas driven heptafluoropropane drug filling system are as follows.
Pharmaceutical storage tank: used to store liquid heptafluoropropane pharmaceuticals.
Filling equipment: including gas booster pump, metering device, pipeline system, etc., to complete the filling of required chemicals into fire extinguishing steel cylinders.
Pressure monitoring and control system: used to monitor the pressure during drug filling, ensuring that the drug is filled at the appropriate pressure.
Safety valve and pressure relief device: In order to prevent excessive pressure during the filling process, the equipment is equipped with a safety valve.
Temperature regulation system: In order to ensure that the medication is filled at the appropriate temperature, some systems are equipped with temperature control devices to prevent the medication from overheating or overcooling.
Before filling the heptafluoropropane agent, the storage container or gas cylinder that needs to be filled with heptafluoropropane should be inspected to ensure that it is not damaged, corroded, or has other defects. Confirm that the pressure of the bottle body is normal, and if necessary, conduct a pressure test on the bottle body to ensure that it can withstand the high pressure after filling. The filling process should be carried out in a clean and well ventilated environment to avoid the mixing of external pollutants. Operators need to wear appropriate protective equipment, including gloves, goggles, etc., to prevent potential hazards in case of drug leakage.
Before filling heptafluoropropane, weigh the empty bottle first, and then weigh it again after filling to ensure accurate filling quantity. Use specialized filling equipment to fill the heptafluoropropane agent into the fire extinguishing bottle. During this process, liquid heptafluoropropane is usually used and pressurized into the container.
During the filling process, pressure and temperature should be closely monitored to avoid excessive filling or overheating of the gas cylinder. After filling, ensure that the gas cylinder is sealed properly to prevent leakage. Recheck the weight of the gas cylinder and confirm that the filling amount of the medication meets the design requirements. Check the pressure of the bottle to ensure it is within the specified range. After filling, label each filled gas cylinder and record the filling date, dosage, operator, and other information for subsequent maintenance and inspection.
Although heptafluoropropane is colorless and odorless, its leakage may have an impact on the environment and human health, so it is necessary to wear appropriate protective equipment during operation. During the filling process, gas detection equipment should be used to monitor whether there is a leakage of heptafluoropropane in the working environment, ensuring the safety of operators. The filling of heptafluoropropane medication needs to be carried out in a unit with professional qualifications, and strictly comply with relevant safety and operational standards.
