Oil circuit system is an important part of air compressor circulation system.
In the normal operation process, the oil system will produce friction because of the rotation of the machine, and the heat generated by friction will make the temperature of the lubricating oil rise. Low temperatures are very helpful for the oil system that needs to be cooled.
But for standby equipment or air compressors that do not start all the year round, when they start up again at low temperature, the oil pipeline may condensate because of low temperature, so starting will fail, so it is necessary to check the oil pipeline system to see if the lubricant is in normal condition.
For the storage of lubricating oil, it is generally required to store in a heated room. If stored outdoors, the lubricating oil may be frozen and condensed because of the low temperature, and can not be used immediately when needed.
The influence of low temperature in winter on air compressor is good or bad, not only in the operation of air compressor, but also in the maintenance of air compressor and the storage of spare parts. Attention should be paid to the operation of air compressor at low temperature, regular maintenance and prevention of air compressor failure to ensure the safety and normal operation of production.
For some electric air compressors, because of the high oil viscosity in the lubricating parts of the unit and the relatively low voltage in some mines when they start in winter, it is easy to cause relatively difficult start-up when they start up. Generally, the method is to first discard 2-3 cycles of the unit and point the air compressor 3-4 times, so that the air compressor can start up after the unit is started. Running for 10 minutes, stopping, and then restarting, can generally make the unit run normally.
