Dongguan Saisen specializes in customized services for fluid pressure control equipment products. We provide a one-stop solution for "heptafluoropropane filling equipment" based on the actual needs of our customers.

1、 Introduction to heptafluoropropane filling equipment:

This medication filling equipment (automatic filling of heptafluoropropane medication) has the functions of vacuuming, filling medication, and nitrogen filling for heptafluoropropane fire bottles. This device requires 6-8 bar compressed air drive, with a flow rate of over 1 m ³/min. The higher the compressed air pressure (not exceeding 8 bar), the greater the flow rate, and the faster the filling speed. Before filling the medicine, the bottle is first evacuated to -0.07MPA, and then the medicine is filled. The equipment is equipped with an electronic scale that can set the filling weight. When the set weight is reached, the filling will automatically stop and an alarm will be issued. Then fill the bottle with nitrogen gas, and the equipment is equipped with a precision pressure gauge that can accurately display the pressure of the filled nitrogen gas.

2、 Application of heptafluoropropane filling equipment: used for filling heptafluoropropane agent from large bottles into fire extinguisher bottles (large cans poured into small cans)

4、 Description of heptafluoropropane filling equipment:

The heptafluoropropane filling equipment uses compressed air as a power source to drive the filling and transportation of chemicals. When the weight of the transportation reaches a certain value, a signal is transmitted to the electromagnetic valve at the gas source through a sensor, and the gas source is closed, causing the pump body to stop working; Connect the nitrogen source, reduce the pressure to the required level with the pressure reducing valve, and then open the nitrogen high-pressure valve to inject nitrogen gas; Close the nitrogen needle valve when the required nitrogen pressure is displayed on the precision pressure gauge; Filling completed; It has the characteristics of small size, light weight, simple operation, reliable performance, and wide applicability. Specially suitable for the filling and use of heptafluoropropane in the firefighting industry;

Note: Important precautions: The high-pressure cut-off valve is a conical valve needle, and the closing force should not exceed 18N. During use, if there is leakage in the shut-off valve, the correct operation should be to release the pressure and then close it again. Avoid excessive force that may damage the valve core and shorten the service life of the valve. System composition and configuration

5、 Operating procedures for heptafluoropropane filling equipment

1. Add lubricating oil to the oil mist generator of the binary system, using 10 # or 20 # mechanical oil in the south and antifreeze mechanical oil or low pour point hydraulic oil in winter in the north.

2. Close the low-pressure air source ball valve, connect the air source, and adjust the pressure reducing valve on the coupling to ensure that the air pressure is not greater than 0.8 MPa (0.8 kgf/cm ²)

3. Place the gas cylinder, turn off the medication switch, turn off the high-pressure nitrogen switch, turn on the vacuum pump switch, and start the vacuum pump to evacuate.

4. After vacuuming, turn off the high-pressure switch of the vacuum pump, close the unloading valve, open the high-pressure needle valve, open the low-pressure gas source ball valve, start the heptafluoropropane pump, and observe the weight change on the electronic scale; After reaching the set pressure, it will automatically stop working. At this time, turn off the medication switch.

5. After the drug filling is completed, open the nitrogen needle valve and observe the pressure gauge (standard pressure gauge) in front of the pressure reducing valve. Reduce the pressure to the required pressure through the pressure reducing valve (precision pressure display behind the pressure reducing valve) and add nitrogen to the already filled bottle;

6. After the operation is completed, close the high-pressure needle valve, manual ball valve, and nitrogen needle valve;

6、 Precautions and maintenance of heptafluoropropane filling equipment during use

1. When carrying out filling work, the operator must pay attention to the sealing of the connecting pipeline. If the connection is not secure, stop filling immediately.

2. There must be lubricating oil inside the oil mist device to lubricate the pneumatic pump. Adjust the oil level to 15-20 drops per minute, oil cup

Internal refueling must be carried out when there is no air pressure.

3. The accumulated water in the water separation filter should be drained at any time, and the water in the filter cup should be cleaned regularly. When cleaning, mineral oil should be used first

When cleaning, dry the cup with low-pressure air and avoid using solutions such as acetone, acetaldehyde, acetate, toluene, etc.

Because these solutions will damage the cup.

4. The conveying medium of this machine must be kept clean. If the filling medium is not clean, it will result in poor sealing of the valves of the machine, which will affect its use.
