What Issues Should Be Noted When Using a Dry Air Generator - Yangzhou Darui
Darui Electric recommends for you
The dry air generator is specially designed to provide pure dry air with a dew point of -40℃ to -70℃ during the installation and maintenance of large power equipment such as transformers and reactors. It can replace traditional drying methods such as hot oil circulation, nitrogen supplementation, and vacuum pumping, and is more economical, safe, and environmentally friendly. It comprehensively utilizes cold dryers, adsorption dryers, coalescing oil-water separators, and ultra-precision filtration, scientifically combining three drying and purification processes: freezing, adsorption, and filtration. Through reasonable pipeline connections and capacity matching, it achieves economical operation and produces dry air with low dew point quality. Moreover, with an integrated design, PLC automatic control, automatic detection of various operating parameters, compact and reasonable structure, good drying effect, low regeneration gas consumption, long working life, and excellent composite desiccant performance, its lifespan is more than three times that of ordinary adsorbents. It adopts microcomputer program control, energy-saving, safe and reliable.
Precautions for Dry Air Generator:
1. Because the compressor is an inductive load, the instantaneous current during power on/off is several times higher than normal operation, making it easier to blow fuses. An 8A fuse should be used.
2. If the compressor does not start during operation and the thermal protection relay activates, it indicates that the compressor temperature is too high. It will automatically return to normal after cooling.
3. To avoid excessive water accumulation in the machine affecting air purity, press the drain switch for a few seconds before each shutdown. (You can place a plastic bottle under the drain outlet to prevent water splashing.) Drain at least once a day.
4. Observe the color-changing silica gel through the observation window. Users can replace the silica gel with new one or perform drying treatment as needed.
5. To ensure gas purity, the activated carbon needs to be replaced every 1000 hours of operation (activated carbon: 20-40 mesh, pencil lead type).
6. Since the compressor operates in an open circuit mode, lubricating oil will be discharged with water, causing consumption. Therefore, after one year of use, add lubricating oil to the compressor appropriately. The oil filling port is next to the compressor outlet (or can be filled from the inlet). It is recommended to add 200 grams of No. 18 refrigeration oil.
7. The inlet filter needs to be cleaned regularly (the cycle depends on indoor dust conditions; ultrasonic cleaning can be used) to maintain smooth air intake. Otherwise, it may cause increased compressor load and heating, and overheating protection may lead to shutdown when the temperature is too high.
