The efficient, stable, and energy-saving characteristics of a PSA nitrogen generator have made it widely used in modern industry. In terms of operation, the management of a PSA nitrogen generator is actually not complicated. If there is a linkage setting between devices, the system can be started with just one button. If there is no linkage, it can also be quickly and smoothly turned on or off by simply following a few steps.

• Startup steps:

  - Turn on the main power switch of the control cabinet.

  - Start the refrigerated dryer.

  - Turn on the air compressor.

  - Turn on the main switch of the nitrogen generator.

  - Adjust the pressure of the pressure reducing valve.

  - Open the emptying valve to adjust the flow rate to the rated flow rate, then open the sampling valve. After the nitrogen purity meets the standard, close the emptying valve and open the gas delivery valve.

• Shutdown steps:

  - Close the nitrogen gas delivery valve.

  - Turn off the switch of the nitrogen generator control cabinet.

  - Turn off the air compressor.

  - Turn off the refrigerated dryer.

  - Turn off the main power supply.

  - Record the shutdown status and time, and wait for the next startup.

Precautions for operating the PSA nitrogen system:

  - Ensure that the operator has received professional training and is familiar with the equipment's operating procedures.

  - Disconnect the equipment power supply before performing maintenance and care.

  -The start and stop intervals of the refrigerated dryer need to be more than 5 minutes; frequent starts and stops are not allowed.

  -Control the monitoring gas flow rate of nitrogen purity within 300-400ml.

  -During operation, pay attention to the drain conditions of the air compressor, filter group, refrigerated dryer, etc., to ensure normal drainage without failure.

  -During equipment operation, be alert for abnormal sounds and smells, which may indicate equipment failure.

  -Keep the surrounding environment of the equipment clean and ventilated to avoid equipment failure caused by environmental factors.

Although the startup and shutdown operations of a PSA nitrogen generator are not complicated, they still need to be strictly implemented because they are related to the safe operation of the equipment and the personal safety of the operators. Improper operation may lead to safety accidents and unnecessary losses.
