At present, a water-lubricated oil-free twin-screw air compressor (including the already existing and applied water-lubricated oil-free single-screw air compressor) is used in the market, and water is used instead of lubricating oil. When the ambient temperature is close to 0 degrees, the lubricating water in the air compressor will freeze. If you do not pay attention to melting ice, the temperature will rise instantaneously when the machine is turned on in the morning or it will be shut down due to overheating. In severe cases, the host may be stuck due to lack of water. Therefore, the ambient temperature of the air compressor must be controlled above 0 °C, and the correct jog 2-3 times when starting up, so that the lubricating water can be circulated to prevent the high temperature of the air compressor during operation.
When the air compressor is out of use for a period of time or the ambient temperature is close to 0°C, the air compressor should not be started directly. It is necessary to wait until the ice melts, drain and replenish water, and then add 3-5 liters of pure water to the air inlet, and mix it up. Turn the air compressor several times to make the air compressor lubricated before starting. Be sure to release the water in the gas tank and the water in the pipes before leaving get off work, otherwise the valves and pipes may be frozen and cracked.
