Product Description

Product Description

 

Solution A: Filling machine Vacuum pump weighing system

Solution B: Solution B added some sensors, electromagnetic valve, vacuum pump, and the electronic scale based on solution A

1. Machine Composition

Filling system (filling pump, precision pressure gauge, pressure reducing valve, high pressure electromagnetic valve, electric control part, etc.) and non-standard parts (weighing machine, vacuum pump)

 

driving the HFC-227ea/FM200 filling and conveying, when the transmission weight reaches a certain value, the sensor signal is transferred to the gas electromagnetic valve, turn off the gas supply, pump stops working. Then Connecting the nitrogen gas source, open the high-pressure nitrogen gas valve injection of nitrogen; when precision pressure gauge shows the needed nitrogen pressure then close the nitrogen valve; filling finished; It has the characteristics of small volume, light weight, simple operation, reliable performance. Especially suitable for the filling ofheptafluoropropane in fire fighting industry.
2. Filling equipment using the compressed air as power source,

 

The driving source: compressed air (by air compressor 3-8 bar) Medium: HFC-227ea/FM200/Heptafluoropropane Output interface: ZG1/4 internal thread
3 .Main parameters:

Operating Procedure:

1. Add lubricating oil to the FR.L Combination;
2: Close the drive low-pressure gas valve, connected to the compressed air source and let pressure not more than 0.8MPa (8bar)it;
3. Place the good empty bottle, close the HFC-227easwitch, close the high pressure nitrogen switch, open the vacuum pump switch, start the vacuum pump to vacuum;
4. When vacuum pumping is completed, close the vacuum pump pressure switch, close the unloading valve, open high pressure needle valve and low pressure gas source valve, the filling pump starts, observing the change of the weight of the electronic scale; (the set pressure is reached automatically stop working), then close the switch of HFC 227ea/FM200/Heptafluoropropane;
5. After the completion of the HFC-227ea filling, open nitrogen valve, observe valve before the pressure gauge (pressure standard table), through pressure reducing valve to the desired pressure (pressure reducing valve after the precision pressure display) by adding nitrogen to the filling bottle; 6. After the completion of the operation, close the high-pressure valve, manual valve and nitrogen valve.

Operation bench

The operating table is composed of various pressure gauges, valves, buttons, with corresponding signage instructions, and is easy to operate.

Refrigerant booster pump+vacuum pump

The closed box contains valves, refrigerant booster pump, and vacuum pump. Refrigerant booster pump: to boost the pressure of HFC227ea medium. Vacuum pump: before boosting the pressure of the medium, the gas cylinder needs to be evacuated.

 

Inlet

N2 inlet Driven air inlet: air compressed pressure 3-8 bar HFC227ea inlet

 

Outlet

Unloading port High pressure port

Control box

Used to control electronic scale

Electronic scale

Weight range 0-500kg can be choice

Automatically stops filling when the set weight is reached
