Is air compressor lubricating oil the more viscous the better

Air compressor lubricating oil has many functions and effects such as cooling, sealing, lubrication, etc. It is a necessity during the use of air compressors. The good lubrication effect can not only give full play to the overall efficiency of the air compressor unit in operation, improve the efficiency of the equipment, but also reduce the failure rate and reduce the maintenance cost. Therefore, the choice of lubricating oil is a problem that air compressor users need to consider carefully, which will affect the normal operation of the equipment and the smooth progress of production. The air compressor lubricant must reach a certain viscosity to meet the relevant lubrication, sealing, and cooling effects. Lubricating oil with too low viscosity is not easy to form a strong enough oil film, which will accelerate wear and shorten the service life of parts. So is the lubricating oil for air compressors as viscous as possible?

　　 The answer is of course no.

　　1 Although the higher the viscosity of the lubricating oil and the thicker the oil film, it helps prevent the friction surface from wearing, but the frictional resistance is also higher, the power loss increases, and the specific power of the compressor increases. Use lubricating oil with high viscosity and start at low temperature. After a period of shutdown, the lubricating oil on the friction surface has been lost. However, the viscosity is high and the flow is slow. It cannot be added to the friction surface in time to form a lubricating oil film, which will cause the machine parts to grow Time is in a state of dry friction and semi-dry friction, which leads to increased wear and tear of mechanical parts.

　　2 The viscosity of lubricating oil is large, and the same lubricating effect requires a larger amount of oil, which increases oil consumption. Under the condition of ensuring lubrication, choosing lubricating oil with lower viscosity can achieve the purpose of fuel saving.

　　 In summary, air compressor oil is not as viscous as possible. As the saying goes, too much, too high viscosity, not only can not achieve the corresponding lubrication effect, but will cause equipment loss and unnecessary waste.
