Fully automatic multi intelligent gas distribution system

The working principle of the fully automatic multi intelligent gas distribution system equipment is to configure high-purity air (N2), O2, CH4, CO2 according to the required test ratio as needed. It has a built-in gas distribution program and can be started with one click to meet the needs of different experimental mixed gases. This system is debugged and operated on the device's built-in analyzer to detect and verify the mixing ratio, adjust the mass flow meter data input relative to the required ratio, complete a series of actions, and store the gas flow rate and type. The equipment is equipped with a touch screen to select the working status and display the workflow. The PLC controls the solenoid valve, gas mass flow meter, and pressure transmitter to work. The pressure regulating valve is used to adjust the gas pressure required during the testing process.

Fully automatic multi intelligent gas distribution system: The gas distribution system adopts a fully automatic multi variable gas distribution equipment mainly composed of a quality flow transmitter imported from Japan. The self written program is completed in the PLC, and under the control of pressure sensors and pneumatic valves, the quality flow meter calculates the output flow rate of each gas and transmits the data to the quality flow transmitter to strictly control the injection amount of other gases. Ignoring the original gas pressure and flow rate changes, accurate gas distribution is always obtained at the point of use of the mixed gas. The mixed gas output end is equipped with a sampling analysis interface and is monitored by an external analyzer or chromatograph to verify the measured content in the mixed gas. The touch screen completes data acquisition, all parameters are clear and visible, and the gas distribution ratio is changed. One click completion and one click storage are performed. The equipment has an interlocking function to prevent misoperation. The data output end is equipped with a 485 interface. Online can complete remote data transmission, Remote control.

The gas distribution cabinet adopts partition equipment: the electrical part is fully enclosed with positive pressure design, and the electrical control part inside the cabinet is separated from the gas distribution working area. When the working power supply is connected, the nitrogen inlet valve is automatically opened, and the pressure is adjusted to slightly higher than atmospheric pressure through the pressure reducing valve, which is used as a micro positive pressure blowing device inside the chassis. A combustible gas detector is added to the top of the mechanical part of the equipment to detect combustible gas leaks in real time. Once there is a gas leak, a level 2 alarm is triggered, A sound and light alarm is triggered, and B combustible gas content continues to rise, the second program is activated to urgently cut off the combustible gas source. The equipment stops working until the alarm is eliminated, and various alarms are set up to ensure the normal operation of the proportioner. It can be isolated from the outside of the chassis to a certain extent and has explosion-proof and. Meets the requirements of safety production.
