Precautions for Dry Air Generator - Yangzhou DARUI
DARUI Electric recommends for you
Dry Air Generator, specially designed for large power equipment such as transformers and reactors during installation and maintenance, providing dry air with a dew point of -40℃ to -70℃. It can replace traditional drying methods such as hot oil circulation, nitrogen supplementation, and vacuum drying, 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 of freezing, adsorption, and filtration. Through reasonable pipeline connections and capacity matching, it achieves economical operation and produces dry air with low dew point. Moreover, with 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 good composite desiccant performance, its lifespan is more than three times longer than ordinary adsorbents. It adopts microcomputer program control, energy-saving, safe, and reliable.
Precautions for Dry Air Generator:
1. Since 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 overload relay activates, it indicates the compressor temperature is too high. After cooling, it will automatically return to normal.
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 connect the drain outlet to a plastic bottle to prevent water splashing.) Drain at least once a day.
4. Observe the condition of 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 is 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, appropriately add lubricating oil to the compressor. The oil filling port is next to the compressor outlet (or can be added through the air inlet). It is recommended to add 200 grams of No. 18 refrigeration oil.
7. The intake filter needs regular cleaning (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 heat generation. If the temperature is too high, thermal overload protection may activate and cause shutdown.
