<1>, When taking the instrument out of the packaging box, please check whether the accessories and warranty card are complete.
<2>, Check the instrument appearance and interior for any serious damage caused by transportation or other abnormal phenomena.
<3>, Preparation before startup and connection:
(1) Replace the sealing plug on the "Air Inlet" port on the rear panel of the instrument with the "filter" from the accessories.
(2) Tighten the sealing nut on the "Air Outlet" port on the rear panel to ensure no air leakage.
(3) Reliably ground the grounding terminal (middle blade) of the instrument power cord and the chassis shell.
(4) Connect the power supply, turn on the switch, and the instrument starts working. At this time, the output pressure gauge pointer gradually rises to 0.4 Mpa (set at the factory). After a few minutes, the compressor stops working (set internally). Then loosen the sealing nut on the air output A slightly to allow some exhaust. Soon, the compressor will automatically start. During the repeated cycle of compressor start-stop-start, the pressure gauge should always remain at 0.4Mpa, indicating that the instrument is normal. (If the exhaust volume exceeds the rated value, the pressure gauge will not stabilize at 0.4Mpa).
(5) During the start-stop cycle of the compressor, it will automatically discharge some water each time it stops working, but this cannot completely replace manual drainage, so frequent manual drainage is still necessary.
(6) After the above is normal, turn off the power, remove the pressure cap on the air outlet, connect the instrument with a pipe of appropriate outer diameter and ensure sealing without leakage.
(7) When working again, simply turn on the power switch.
(8) If only one output is used, seal the other outlet with a blind nut.
Precautions:
1. Because the compressor is an inductive load, the instantaneous current during power on/off is several times higher than normal working current, which can easily 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 that the compressor temperature is too high. It will automatically recover after cooling down.
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 a plastic bottle to the drain port to prevent water splashing). Drain at least once a day.
4. Observe the color-changing silica gel through the observation window. Users can replace with new silica gel 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 air inlet filter needs regular cleaning (the cycle depends on indoor dust conditions, can be cleaned with ultrasonic) to maintain smooth air intake. Otherwise, it may cause increased compressor workload and heat generation, and overheating protection may trigger shutdown if temperature is too high.
Purpose and Functions:
Intelligent Dry Air Generator, specially designed to provide high-purity dry air with dew point as low as -60℃~-70℃ for large power equipment such as transformers and reactors during installation and maintenance. It can replace traditional drying methods such as hot oil circulation, nitrogen supplementation, and vacuum drying, and is more efficient, economical, safe, and environmentally friendly.
Intelligent Dry Air Generator, during installation and maintenance of power equipment, is not affected by external climate changes. Especially for overnight operations, simply seal the flanges and fill with dry air to 0.02-0.03Mpa. No oil injection, nitrogen supplementation, or vacuuming is needed. Transformers, reactors, and other power equipment will not be affected by moisture, greatly reducing workload, shortening construction periods, and improving installation and maintenance quality.
It is also suitable for air drying and circulating drying in warehouses, packaging, electronics, pharmaceuticals, and other industries. It is also applicable for drying nitrogen, generator hydrogen, and SF6 equipment.
Replaces traditional drying methods, efficient, economical, safe, and environmentally friendly. It integrates air compression, cold drying, and adsorption, and is freely movable.
Product Principle:
Atmospheric air enters the air storage tank through the air compressor. Most of the moisture is compressed and liquefied and discharged through the drain valve, achieving the first drying of the air. Then it enters the refrigerated dryer, where water vapor condenses into water, achieving the second drying. Then it enters the adsorption dryer for the third drying, adsorbing the remaining trace moisture. Finally, it passes through a high-precision air filter and is delivered to the equipment requiring dry gas.
Performance and Features:
It mainly consists of four parts: air source system, refrigeration drying system, adsorption drying system, and electrical control system, forming a mobile high-purity dry air generation device.
Air source system composition: Composed of air dust filter, oil-free air pump (or screw oil-free air compressor), radiator (air-cooled), air-water separator, and filter, outputting clean and oil-free gas.
Refrigeration drying system composition: This device mainly adopts imported fully enclosed high-temperature compression refrigeration units, with stable and reliable performance, providing greater cooling capacity. The system configuration adopts imported fully enclosed compressor units, air heat exchanger, evaporator, air-water separator, and precision filter. During the refrigeration process, R22 refrigerant first passes through the fully enclosed high-temperature compression refrigeration compressor, cooler, desiccant, solenoid valve, and finally returns to the refrigeration compressor through the evaporator, achieving a low-temperature environment of 0-5℃ inside the evaporator.
Electrical control: The main control electrical parts adopt Schneider Electric; the whole machine has stable, safe, and reliable electrical performance.
