▶Product Characteristics:
1. Simple and safe operation; daily use only requires replenishing distilled water.
2. Simply turn on the power switch, and the instrument can produce gas. The output pressure is stable, and the hydrogen flow is displayed for more intuitive visibility.
3. The air section uses an oil-free air compressor, which improves the purity and dryness of the air.
4. All gas pathways are made of stainless steel tubes, electrolytically polished, and ultrasonically cleaned. Overpressure protection devices and two-stage purification are installed.
5. Precious metals are selected for the electrolysis materials, effectively improving electrolysis efficiency, maintaining constant cell temperature, and greatly extending the service life of the electrolytic cell.
6. The output flow is stable with automatic tracking, purity does not degrade, and continuous use is possible.
7. The instrument comes with automatic water replenishment and drainage functions to avoid dry burning due to water shortage.
8. It can be used with various chromatographs, replacing hydrogen and air cylinders, making it safer and more environmentally friendly.
An air generator generally consists of an air pump/compressor, a pressure stabilization system, a pressure control system, a purification system, and a display system.
The air generator uses a compressor as the power source, absorbs filtered outside air, and forms high-pressure gas inside the compressor. It then enters the air storage tank, and after decompression, purification, pressure stabilization, and drying, it outputs pure air, which can serve as a gas source for gas chromatography.
Daily maintenance and operation
1. To ensure gas purity, the activated carbon in the air generator should be replaced every 1000 hours of operation.
2. Replace the color-changing silica gel in a timely manner: During normal use, observe the changes in the color-changing silica gel in the purification system. When half of the color-changing silica gel turns red, replace it with new silica gel or regenerate the reddened silica gel in an oven before reuse (Note: Do not put the drying tube together with the silica gel into the oven during regeneration, as this may damage the tube); otherwise, the moisture in the air increases, making it difficult for the detector to ignite or causing it to extinguish. After replacing the silica gel, check the airtightness of the connections at both ends of the purification tube. If there is any leakage, replace the sealing gasket or the purification tube promptly.
3.Integrated Hydrogen/Air Dual-Purpose Generator Small Air Separation Unit AYAN-NH300 Packing treatment method: Bake the color-changing silica gel in an oven at 120°C for 12 hours. Calcine the molecular sieve in a muffle furnace at 250°C-300°C for 24 hours.
4. Frequently replace the filter at the air inlet of the generator: The filter can be soaked in clean water or cleaned ultrasonically, then dried and reused. Over time, the filter at the air inlet may become clogged, causing insufficient air intake, which prolongs the working time of the air compressor and shortens its service life. (The frequency of filter replacement depends on the working environment of the instrument. Under normal conditions, it is recommended to replace or clean the filter every six months.)
5. Frequent draining: To avoid excessive water accumulation inside the machine affecting air purity. At the end of the experiment, first cut off the power, then press and hold the drain button in the instrument to drain until the residual gas in the air storage tank is basically exhausted. This helps to discharge accumulated water or oil in the storage tank, ensuring air quality.
If the compressor does not start during operation and the thermal protection relay activates, it indicates that the compressor temperature is too high. After cooling, it will automatically return to normal.
6. Since the air generator compressor is an inductive load, the instantaneous current during power on/off is several times higher than normal operation, making fuses more prone to blowing. An 8A fuse should be used.
7. If the compressor does not start during operation and the thermal protection relay activates, it indicates that the compressor temperature is too high. After cooling, it will automatically return to normal.
The dry air generator uses a multi-stage filtration system. Due to the adoption of our company's independently developed "QL composite molecular adsorbent," regardless of the moisture content in the air, the dew point of the product gas will quickly drop below -70°C.
Integrated Hydrogen/Air Dual-Purpose Generator Small Air Separation Unit AYAN-NH300 The small water droplets and particles flowing with the compressed air are intercepted when passing through the first-stage filter; the compressed air then enters the refrigerator, where its temperature drops to 4°C, and water vapor again reaches saturation in large quantities and condenses into liquid water, which settles in the refrigerator; after passing through precision filters with filtration accuracy of 0.1µm and 0.01µm, the atmospheric dew point of the compressed air is approximately -22°C; after entering the adsorption tower, water molecules in the air are adsorbed by the QL composite molecular adsorbent, while other air components are discharged from the dry air generator. The dew point of the air after adsorption is below -70°C, equivalent to a moisture content of 0.005 grams per cubic meter of air (at 20°C, the saturated moisture content in air is 17.3 grams).
The rapid development of human society has led to a continuous increase in energy demand. It is an inevitable trend for primary energy sources used by humans to transition from fossil fuels to renewable energy sources such as solar and wind energy. However, these renewable energy sources typically lack pathways for conversion, storage, and recovery. Hydrogen energy, as a secondary energy source, precisely provides an efficient pathway for the conversion and storage among primary energy, chemical energy, and electrical energy.
