How to Deal with The Air Compressor Soaked in Flood

Since July 17, Henan Province has experienced extremely heavy rains, with large torrential rains in the central, western and northwestern regions, and extreme torrential rains in some areas. As of 4 o'clock on the 22nd, heavy rainfall caused 3.004 million people in 103 counties (cities, districts) in Henan Province and 877 towns and towns. 33 people died and 8 people were missing. The affected area of crops was 215.2 thousand hectares, the affected area was 77.9 thousand hectares, and the area of no harvest was 10.3 thousand hectares.

For air compressors that have been soaked by floods, do not power on or turn on the compressor after the flood water recedes. Please follow the methods below to deal with it.
1. For the air end soaked in water:Disassemble the intake valve first. If mud or other debris gets in, be sure to disassemble the nose and clean the interior thoroughly before reassembling. If only a small amount of water enters, you can pour diesel or kerosene into it and turn the rotor to drain the water. Finally, pour the engine oil in to drain the cleaning oil.
2. For inverters, controllers and other electrical devices soaked in water:First open the inverter panel, dry the inverter with a dry towel, and then use a small blower to dry the drive board, main board, lightning protection board, inverter module and fan, etc., and then use board washing water or alcohol (be careful not to use bananas). Water) scrub it again, then dry it with a small blower, scrub it again for about an hour, and then dry it with hot air. Do not turn on the cleaned and dried inverter immediately after it is installed, and then turn it on again after half an hour of power-on without abnormalities.
3. Contactors, transformers, switches soaked in water:For the contactor above 65, the contactor can be disassembled, and the original parts such as the contact group can be wiped with plate washer water or alcohol, and dried with a blower. The coil should be irradiated with the bulb of a bath heater. If there is mud in, be sure to remove the mud. Clean up, and it is recommended to replace small contactors and small switches directly.
4. Motor (including fan motor) soaked in water:Disassemble the end cover of the motor and clean the stagnant water. If there is mud in, be sure to clean the mud, and then use a blower to dry it before drying: low temperature pre-drying, temperature control at 50~70℃, drying The time is 8~14h. High temperature drying; the temperature is controlled at 80~100℃, and the drying time is 1h. The drying time of a small motor is short, and the drying time of a large motor is longer. Use a 500~1000V insulation resistance meter to measure the insulation resistance value of the winding every 1 hour. The insulation resistance value of the motor after drying should be greater than 5MΩ. If it is not reached, continue drying.
5. All three filters and oil should be replaced with new ones.
6. Contact the after-sales service personnel of the air compressor.
