Important indicators of oil

A, flash point: in the oil contact with the flame, the fire occurs within three seconds when the temperature of the flashing. The higher the better

B, ignition: the temperature at which the oil is ignited. The higher the better

C, viscosity: at 40 degrees Celsius, the flow rate of oil, screw air compressor are generally 46, only a small number of air compressor brand with 32, such as Japan's Kobelco, Hitachi and the United States Sullair. Test whether the oxidation of oil or have to life, to see changes in viscosity, mineral oil generally can not exceed 15%, such as more than a long time to use will be knot or carbon.

D, viscosity index: oil by the temperature change and change the viscosity index. The higher the better the index of mineral oil is generally less than 120.

E, pour point: the minimum temperature in the oil to keep the flow, pour the lower the better. Such as mineral oil pour point in the minus 19 degrees --- 21 degrees or so. Such as China's northern cold regions, the winter temperature is low, high pour point of mineral oil, air compressor can not start, we must start the air compressor heating, if the synthetic oil will not be such a problem.

F, density: is the proportion of the general oil in the 0.85 or so, in addition to Sullen's SULLBUE32 # and Ingersoll Rand super coolant around 0.99

G, acid value: the new oil will not exceed 0.09, the old oil used in the air compressor, impurities, iron, acidic substances will increase the acid value of the oil, which will accelerate the oxidation of oil, such as oil The value of more than 1, on behalf of the high degree of pollution of oil, the proposed replacement.

O, oil classification: mineral oil (a hydrogenation, dewaxing, distillation and other processes known as the class I base oil; secondary process known as the second class; the best three times known as the class III, known as semi-synthetic Oil, foreign or classified as mineral oil. The real semi-synthetic oil should be more than 20% of the base oil to add more than 20% of the synthetic ester, we can call our semi-synthetic oil. Synthetic oil (poly Alfa olefins referred to as PAO, ester Type synthetic oil abbreviation POE, ether synthetic oil referred to as PAG, etc.)

P, Lubricant product composition: base oil and additives (antioxidants, anti-emulsifier, rust inhibitor, defoamer, viscosity improver, dispersant, high temperature ester, etc.) to reconcile the product.

The role of air compressor oil in air compressor

A, cooling: air compressor in the work will produce a lot of heat, oil has played a role in the heat.

B, lubrication: oil on the metal surface is equal to the formation of a layer of protective film to reduce wear and tear, 46 than the 32 oil film thicker, especially when the cold start to protect the metal surface.

C, seal: screw host compression chamber lubricants can reduce leakage.

D, the sound: reduce the host running noise

Air compressor oil use cycle

A, the life of air compressor oil is mostly determined by its own base oil category, the import brand of mineral oil is generally used within 3000 hours to be replaced, semi-synthetic oil cycle is in 6000 hours, synthetic oil can use 8000 Hours to 16,000 hours.

B, air compressor manufacturers to set the use of the cycle is generally the standard operating conditions (clean air, operating temperature within 95 degrees, the normal operation of air compressor, etc.), harsh conditions will shorten the oil life.

C, in the aftermarket must understand the history of air compressor oil, if the previous oil problems or the use of the brand is not a regular brand of oil, please tell our engineers to properly handle. Because the poor oil oxides will remain in the machine, a serious impact on the life of new oil.

Air compressor oil often problems

A, kneading: air compressor oil base oil is not good, there are more impurities in the gray matter, such substances are easy to oxidize, through the high temperature and air oxidation reaction, as the same asphalt oil sludge, serious time Resulting in air compressor head locked, the general kneading precursor is compressed air becomes smelly, air compressor running current high.

B, carbon: air compressor under high temperature operation, especially after more than 95 degrees, the oil light and heavy components will be separated, after oxidation like paint adsorbed on the surface of the parts, will make the oil fine separator block, the head oil seal wear and tear Oil, bearing life shortened.

C, oil emulsification: air compressor long-term low-temperature operation, the machine's water can not be evaporated in time, oil and water mixed emulsion imaging milk-like liquid.

D, air exports higher oil content: oil oil separation is poor, the base oil in the hydride more, making it difficult to separate with the compressed air.

E, the old oil color anomalies: Often the oil color will become dark red or black, but if purple and other colors that improper use of oil additives, it is recommended to replace the oil in time.

F, oil bubble at the end: usually the proportion of oil defoamer added inappropriate, and sometimes lead to insufficient oil back, affecting the life of the machine bearings.
