Influence of cold weather on air compressor

Time: 2022-05-25 Views: 1215 times

   Air compressor is an important component of PSA oxygen/nitrogen production system,Working in cold temperatures will have a great effect on it,Because of the low temperature,The lubricating oil in the air compressor circulation system will become viscous,Affect the service life of the machine,另外,Cold air into the air compressor will encounter heat to produce a lot of water vapor,The efficiency of the molecular sieve in the system decreased。In order to eliminate these problems, it is necessary to regulate the use of air compressors and reduce the impact of low temperatures on equipment。

1, pipeline cold protection because the water in the compressed air will be discharged through the automatic drainage valve, at low temperatures, it may freeze in the pipeline or other parts。Therefore, it is necessary to winterize the electronic drainage valve and piping system。

2. Keep the temperature of the machine room above zero. Use electric heater to raise and adjust the indoor temperature of the oxygen (nitrogen) machine room;Ensure that the ambient temperature of the equipment room is above 0 ° C。

3. Confirm that the working state of the automatic drainage valve is close to work or before the equipment needs to be shut down, fully open the drainage valve of the pipeline, gas storage tank, dryer, etc., and discharge the condensed water air before closing the valve。

4, shutdown time and space press management If you need to shut down the air separation system, you need to check that the gas emission is displayed as 0 on the display screen after the compressor is shut down.0bar, at the same time must close the valve。Then open the automatic drainage valve of the air compressor, gas storage tank and dryer, and close the air and condensate after completely empting。If it is a long shutdown, you must start once a week and repeat the above operations after 3 hours。

In short, in the low-temperature environment of the air separation equipment, we should always pay attention to the operating status of the air compressor, regularly carry out maintenance and maintenance, prevent the occurrence of air compressor failures, and ensure the smooth progress of production。
