Multi-element gas distribution equipment

Full-automatic hydrogen and nitrogen gas distribution equipment uses thermal mass flow meter and mass flow transmitter as the main body of the full-automatic hydrogen and nitrogen gas distribution equipment. Self-programming is completed in PLC. Under the function of pressure sensor and pneumatic valve, the mass flow meter calculates the nitrogen output flow and then transmits the data to the mass flow transmitter to strictly control the injection amount of hydrogen. Ignoring the raw gas pressure and flow change, the accurate gas distribution is always obtained at the point of use of the mixture, The hydrogen analyzer at the output end of the gas mixture monitors and verifies the hydrogen content in the gas mixture. The touch screen completes the data collection, and all parameters are clearly visible. The gas distribution ratio is changed, and the key is completed, and the key is stored. The equipment has the interlocking interlock function to prevent misoperation. The data output end is equipped with a 485 interface, which can complete the remote data transmission online, and remotely control the working principle of the equipment;

After the hydrogen and nitrogen entering the proportioning cabinet are depressurized and stabilized at the gas distribution inlet, various gas flows and pressures are indicated by various digital gas flow meters, and then the amount to be injected is calculated and controlled by PLC to achieve the mixing content required for proportioning. The ratio automatically adjusts the content of hydrogen and nitrogen to be added when the flow rate of the later stage changes, and the analyzer monitors the percentage content ratio of the ratio gas in real time.
