What is the viscosity index requirement of air compressor oil how to choose

Air compressor oil has a good lubricating effect, which can not only improve the efficiency of air compressors, but also reduce the failure rate and reduce maintenance costs. However, it is closely related to the viscosity index of the air compressor, so what is the viscosity index requirement of the air compressor oil What? how to choose?

　　 Air compressor lubricants must reach a certain viscosity to meet the relevant lubrication effect. If the viscosity is too low, the lubricating oil will not easily form a strong enough oil film, which will accelerate wear and shorten the service life of the parts.

　　Although the higher the viscosity of the lubricating oil and the thicker the oil film help prevent the wear of the friction surface, 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, and it cannot be added to the friction surface in time to form a lubricating oil film, which will cause the machine to grow Time is in a state of dry friction and semi-dry friction, which leads to increased wear and tear of mechanical parts.

　　 In addition, the viscosity of lubricating oil is large, and the same lubricating effect requires a larger amount of oil, which increases oil consumption.

　　 For the viscosity requirements of air compressor lubricating oil, the lower the viscosity, the lubrication cannot be achieved, but the more viscous the better. okmarts.com air compressor believes that it is sufficient to select lubricating oil with suitable viscosity under the premise of ensuring lubricating oil.
