The screw air compressor is a kind of equipment that is often used in our industry, and its role is also very large, and most of the screw air compressors in life belong to the oil-operated system, and the air compressor oil is guaranteed. In addition to mechanical lubrication, it is also responsible for temperature transfer and cooling, etc. So we need to know the knowledge of its oil usage, how often should it be replaced?
How long is the real life of screw air compressor oil?
In fact, the life of screw air compressor oil is not constant. It also depends on the production and operation of the machine. This time, I will introduce the real life of screw air compressor oil.
If the constant discharge temperature of the oil-injected screw air compressor can be reduced by 8~10°C, the life of the compressor oil will be doubled; the discharge pressure of the single-stage oil-injected screw compressor is from 0.3 to 1.3
MPa, due to the different exhaust temperature and oxygen partial pressure, the oxidation rate of air compressor oil is very different, and the exhaust pressure is 0.3
The real life of the lubricating oil of the MPa low pressure air compressor is 3~5 times longer than that of the air compressor with the exhaust pressure of 1.3MPa; the real life of the lubricating oil of the nitrogen compressor is not affected by oxygen, and the real life is much longer than that of the same type of air compressor. ;The oil acid value of similar screw compressors that compress carbon dioxide gas is easy to exceed the standard, and the real life is short;
The two-stage compression atmospheric oil-injected screw air compressor is not only high in energy efficiency due to the low oxygen partial pressure and low exhaust temperature at all levels, but also the real life of the lubricating oil is about 2 times longer than that of the single-stage same type of air compressor; the single-stage compression ratio is high. The compressor oil life of the stage screw air compressor is short;
The variable frequency oil-injected screw air compressor has a lower exhaust temperature during the frequency conversion, and the shearing effect of the compressor on the lubricating oil is lighter than that of the ordinary capacity-regulated air compressor, the real life of the lubricating oil is long, and the frequency conversion time and frequency conversion depth are different. The real lifespan is different; in order to improve energy efficiency, some air compressor manufacturers and users increase the fan of the air-cooled oil-injected screw air compressor and reduce the exhaust temperature of the screw compressor, which not only reduces the power consumption, but also prolongs the The service life of the compressor oil can also achieve the effect of energy saving and environmental protection.
Due to the operation and structure of the equipment, the real life of centrifugal compressor oil is much longer than that of oil-injected screw air compressors.
This is the relevant knowledge points about the real life of screw air compressor oil and how often to change it. I hope that the introduction of this article will give you a better understanding!
