What is the requirement of screw air compressor for air compressor oil?
Suitable viscosity
There are three types of viscosity grades for screw air compressor oils: 32, 46, and 68. It is well known that under the condition of dynamic viscosity, the thickness of the oil film increases with the increase of the viscosity of the oil, but the friction will also increase accordingly. The lubrication and protection of the oil film thickness and the increase of the friction force cause the compressor power consumption and fuel consumption. The increase has become a contradiction in the lubrication of screw air compressors.
How to achieve the dual effects of lubrication protection and equipment energy consumption is the endless pursuit of air compressor oil technology experts.
In this proposition, recommending the appropriate viscosity for the user is one of them. Choosing the right viscosity under the premise of ensuring lubrication has an important influence on reducing energy consumption and ensuring reliable operation of the compressor.
Thermal oxidation stability and sediment control
The thermal oxidation stability and sediment control ability of the compressor oil are important indicators that determine the service life of the compressor oil, and are also an important guarantee for the reliable operation of the compressor, and are the key to reducing the operating cost of the user.
Anti-corrosion and anti-rust performance
The oil cooling components in the compressor are mostly copper parts or copper alloys, which are easily corroded and rusted, especially when the moisture content in the air is high, the catalytic corrosion rust reaction is accelerated. Therefore, the compressor oil must be required to have good corrosion resistance.
