How to Protect the Rotary Screw Compressor in Winter Cold Weather
Now it is the winter, the temperature in most countries are extremely low, to protect the air compressor normal running on winter, Elang compressor has the following suggestions for our valued client:
1. Influence of Low Ambient Temperature on Air Compressor
The temperature difference between day and night in winter is relatively large, so it is necessary to discharge condensate water. If it is not discharged in time, it is likely to freeze and crack the system in the air compressor equipment at night. When the cold air enters the air compressor equipment, it will produce a large amount of water vapor in case of high temperature, which will increase the burden of water vapor filtration of the air compressor equipment. Therefore, we Elang screw compressor suggest that users should pay attention to discharge all air and water after shutdown in winter to ensure the normal use of the rotary screw air compressor equipment.
2. About Oil Level
The temperature difference between day and night in winter is relatively large, so it is necessary to discharge condensate water. If it is not discharged in time, it is likely to freeze and crack the system in the air compressor equipment at night. When the cold air enters the air compressor equipment, it will produce a large amount of water vapor in case of high temperature, which will increase the burden of water vapor filtration of the air compressor equipment. Therefore, we Elang screw compressor suggest that users should pay attention to discharge all air and water after shutdown in winter to ensure the normal use of the rotary screw air compressor equipment.
3.Professional Oil for Screw Air Compressor
The lubricating oil used for rotatory screw compressor shall have the following performance requirements: the oil fraction shall be narrow and the flash point shall be appropriate to ensure safe use and reduce carbon deposition and oil loss; Good thermal oxygen stability to ensure good sediment control; Sufficient viscosity temperature performance to ensure the stability of oil film; Sufficient flow performance can reduce the wear of start-up and stop and extreme temperature, and can also cool down to a certain extent. The synthetic oil is recommended, if you have questions about which oil shall be chosen in different place and different temperature, please contact Elang rotary screw compressor team for more details.
4.Compressor Management during Shutdown
After the compressor is shut down, the compressed air must be discharged completely and the valve must be closed after 0.0bar is displaxyed in PLC. Open the automatic drain valve of air compressor equipment, air tank and air dryer. Close after the air and condensate water are completely drained.
In case of long-term shutdown, it must be started once a week, and the above operations shall be repeated after 3 hours.
In cold and low temperature weather, we should always pay attention to the operation of the air compressor system, do regular maintenance and repair, and prevent the failure of the air compressor equipment, to ensure the smooth progress of production.
In cold winter, no matter the single stage air compressor or the two stage air compressor, not matter the oil free compressor or oil lubricated compressor, we shall pay more attention to the daily checking and maintenance. Elang is a professional screw air compressor manufacturer with 22 years, the compressor is famous for high quality and stable running.
