Air compressor lubricating oil emulsification is a very complex process, not a simple air compressor quality problem, air compressors are designed for long-term operation, air compressor operation time is generally 30-40 seconds, such a short time, due to the oil temperature is too low, all the inhaled water into the air compressor lubricating oil, resulting in air compressor oil emulsification, Mainly because of the compressed air of the air compressor into the crankcase caused by the causes are generally:
1, air compressor oil volume, temperature, humidity, operating rate;
2, the ambient air is humid, the inhaled air moisture is too large;
3. The gap of the piston ring of the compressor piston is too large;
The wet compressed air enters the crankcase through the piston ring gap and mixes its moisture with the splashing air compressor lubricating oil, resulting in the emulsification of air compressor lubricating oil. There is a common misconception that behind the air compressor is a twin tower dryer, its role is to suck up the water in the compressed air, and draining the water in the compressed air is not the function of the air compressor.
Effective methods to deal with the emulsification of air compressor oil:
1. Open the vent valve and run the two air compressors for a long time, preferably more than 20 minutes;
2, replace the piston ring with good sealing performance, which can effectively prolong the emulsification cycle of oil;
3, the radiator under the drainage valve to open some (opening according to the specific situation to adjust), there will be a certain effect;
4. Add desiccant in the downdraft air duct;
5, the ordinary filter can only remove the mechanical impurities in the oil, the water is not much use, need to choose the air compressor oil filter, vacuum oil filter, can effectively remove the impurities and water in the air compressor oil.
