The maintenance of air compressors in winter requires attention to the following aspects:

1.Machine room management: Ensure that the air compressor is placed in an environment not lower than 0 degrees to avoid overcooling. Keep the machine room clean and tidy to prevent water accumulation and ice to prevent slipping and equipment damage.

2.Gas pipelines: For outdoor pipelines, they should be wrapped with insulation materials to prevent them from freezing and bursting. Check the pipelines regularly for water accumulation and remove it in time.

3.Daily operation after air compressor shutdown: After shutdown, all gases, sewage and water should be vented, especially condensed water in gas tanks and pipelines, to prevent condensed water from freezing and causing blockage or equipment damage.

4.Daily operation and maintenance of air compressor: The viscosity of lubricating oil increases at low temperatures, which may cause startup difficulties. This can be improved by increasing the temperature of the machine room or using preheating equipment. At the same time, regularly replace the oil filter to ensure the quality of the lubricating oil.

5.Lubricant management: Use lubricants suitable for low temperature environments and replace them according to the manufacturer's recommendations. Low temperatures may cause the lubricant to have poor fluidity and increase the risk of mechanical wear.

6.Drainage system management: In winter, due to the high humidity in the air, more condensation water is likely to be produced. Condensation water should be discharged and cleaned regularly to prevent moisture accumulation and corrosion.

7.Inspection and maintenance: Regularly check the air compressor's electrical system, gas system, pressure sensors, valves and other key components to ensure their normal operation.

8.Post-processing equipment: For cold dryers and gas storage tanks, pay attention to the anti-freeze measures of the drain outlet and the inside to avoid damage to the equipment caused by ice.

9.Electronic drain valve: Make sure the electronic drain valve is functioning properly to prevent condensation from accumulating.

10.Long-term shutdown management: For air compressors that have been shut down for a long time, it is recommended to start them once a week to maintain the fluidity of the lubricating oil and the normal condition of the equipment.

The above measures can help ensure the safe and stable operation of the air compressor in winter and reduce the risk of failure. Before performing any maintenance operations, you should refer to the operating guidelines and recommendations provided by the air compressor manufacturer.
