Maintenance strategy of air compressor in winter

Time: 2020-12-11 10:01:15

The weather is getting colder and colder. I believe many customers who use the machine can feel that every winter, the air compressor will have various problems that have not occurred before, which causes economic losses. So how should we pay attention to the maintenance of the air compressor in the cold winter?

1.The impact of severe cold on air compressors

After the cold air enters the air compressor, it will produce a lot of water vapor when it encounters high temperature, which will increase the burden of the air compressor post-processing water vapor filtration, so it is necessary to drain the water in the post-processing equipment from time to time.
Compressed air enters the production area through pipes. Some of these pipes are buried in the ground, and some are exposed to the air. Exposed pipes in cold weather may cause part of the moisture to be generated due to the low temperature, and some even increase the moisture, which will affect the normal use of users Note: After shutting down in winter, you must pay attention to venting all gas, sewage, and water, and venting the water, gas, and oil in various pipes and air bags. Because the temperature of the unit is relatively high when the unit is working in winter, the outside temperature is relatively low after the shutdown. After the air is cooled, a large amount of condensed water will be produced, and it will be contained in various control pipes, which is easy to cause hidden dangers such as blockage and cracking of the control pipe

2.The impact of severe cold on air compressor lubricants

The oil circuit system is an important part of the air compressor circulation system. During normal operation, the oil system will generate friction due to the rotation of the machine, and the heat generated by the friction will increase the temperature of the lubricating oil. Low temperature is very beneficial to the oil system that needs cooling.
For standby equipment or air compressors that do not start all the year round, when restarting in low temperature, the oil circuit may condense due to the low temperature and the use of lubricating oil, so the oil circuit system should be checked to see if the lubricating oil is in normal condition
Note: In low temperature conditions, you should always pay attention to the operating conditions of the air compressor, and perform regular maintenance to prevent air compressor failures to ensure safe and normal production.

3.Key points of air compressor protection in winter:

Take cold-proof measures for the electronic drain valve and piping system.
The air compressed from the air machine will contain some moisture. When the condensate is drained through the automatic drain valve, it will be affected by the outside low temperature and freeze in the pipeline or other parts.
Take measures to prevent the temperature of the computer room from cold, and keep the temperature of the computer room above zero.
When the temperature drops, the viscosity of the air compressor lubricating oil will increase, which will have a great impact on the restart of the air compressor after a period of shutdown, and will also affect the life of the machine. The exhaust vent is closed or adjusted to the room to adjust the indoor temperature; when the compressor is stopped or not running, an electric heater needs to be properly activated to adjust the temperature.
Confirm the working status of the automatic drain valve of the air compressor, air storage tank, dryer, and filter.
When off work or when the equipment is shut down, the drain valves of pipelines, gas storage tanks, dryers, etc. are fully opened, and the condensate water is cleaned before closing the valves.

4.Air compressor management during shutdown:

After the compressor is stopped, the gas must be discharged to the display to show 0.0bar and the valve must be closed. Turn on the automatic drain valve of the air compressor, air storage tank, and dryer. Turn off the air and condensate after being completely drained. When the machine is down for a long time, it must be started once a week, and then repeat the above operation after 3 hours. In cold and low temperature weather, you should always pay attention to the operating conditions of the air compressor, and do regular maintenance and maintenance to prevent the occurrence of air compressor failures to ensure the smooth progress of production.
