Nitrogen making machine is a device which uses air as raw material and uses physical method to separate oxygen and nitrogen to obtain nitrogen gas. High quality imported carbon molecular sieve (CMS) is used as nitrogen sorbent, and high purity nitrogen is produced by separating air from the air at room temperature by pressure swing adsorption (PSA). Usually, the two adsorption tower is connected in parallel, and the imported pneumatic valve is controlled by the imported PLC. The pneumatic valve is operated automatically by pressure adsorption and decompression regeneration, and the nitrogen and oxygen separation is carried out to obtain the high-purity nitrogen. Today, let's show you how the switching process of the nitrogen making machine works The operator should be familiar with the performance of the nitrogen machine and be qualified after training. See the following points:
1, before starting the nitrogen machine, first check the various parts of the nitrogen machine (such as switches, valves, meters, lights and other instructions).
2. Starting sequence of nitrogen generator:
1) connect the gas source
2) closed dry and dry machine power switch
3) V101 V102 4) is to open the valve control cabinet power supply, the power switch is closed, the automatic / manual switch automatic, press the start button, the device starts operation.
5) slowly open the valve V104, adjusted to the required flow, to the point of use ".
3. Shutdown order of nitrogen making machine:
1) disconnect the power supply
2) close the valve (such as the use of V101 V102 side, a small amount of aspirated)
3) turn off the cold dry machine power switch
4) close the gas source
5) open the TQ1 TQ2 and shut off the gas in the gas tank.
