When using an industrial nitrogen generator, a series of steps need to be followed to ensure its correct and safe operation. Here are some key steps and precautions:
Connect power and gas source: First, place the nitrogen generator on a stable surface and connect the power cord. Turn on the power switch of the nitrogen generator and wait for a few minutes until the instrument is fully started. Then connect the gas source pipeline to ensure a stable supply of gas.
Inspection and maintenance: Regularly check the operating status and maintenance of the nitrogen generator to ensure its normal operation. This includes replacing the color changing silicone in the drying tube. When 50% of the silicone changes color, the internal packing should be replaced. The color changing silicone gel is baked in a 120 ℃ oven for 12 hours, and the molecular sieve is burned in a muffle furnace at 250 ℃ -300 ℃ for 24 hours.
Adjust flow and pressure: Adjust the flow control valve of the nitrogen generator to achieve the desired nitrogen flow rate. At the same time, check the pressure gauge of the nitrogen generator to ensure that the nitrogen pressure is within the normal range.
Use nitrogen for experiments or other operations: Use a nitrogen generator for experiments or other operations that require nitrogen. After use, turn off the gas source switch and power switch of the nitrogen generator. Disconnect the gas source pipeline, clean the nitrogen generator, and store it in a dry and ventilated place.
Add electrolyte: If necessary, prepare electrolyte. Take a beaker, add an appropriate amount of secondary distilled water or deionized water, then add potassium hydroxide (high-purity) and stir evenly before pouring into a storage cylinder. Simultaneously observe the liquid level tube on the front panel, neither exceeding the upper limit nor falling below the lower limit of the liquid level. After adding the electrolyte, if there is no display in the liquid level tube, gently shake the chassis to allow the electrolyte to enter the liquid level display tube.
Attention: Pay attention to the liquid height. When approaching the lower limit, add distilled water in a timely manner, but do not exceed the upper limit. It is recommended to replace the electrolyte every six months. Pay attention to the color of the discolored silicone inside the drying tube, and replace it promptly if it turns pink. In humid seasons, there may be a small amount of residual moisture in the air storage tank, which can be discharged through the "drain port" at the back of the instrument.
