To say the importance of the accessories in the air compressor, the lubricant is well deserved
The role and main performance of lubricating oil in air compressor
● Air compressor oil is mainly used for lubrication of moving parts and exhaust valves of compressor cylinders, and plays a role of rust prevention, corrosion prevention, sealing and cooling.
● Since the air compressor is always in the environment of high pressure, high temperature and condensed water, the air compressor oil should have excellent high temperature oxidation stability, low carbon deposition tendency, suitable viscosity and viscosity temperature performance, and good Oil-water separation, rust and corrosion resistance, etc.
● Reduce friction and anti-wear, reduce frictional resistance to save energy, reduce wear and tear to extend mechanical life and improve economic efficiency.
● Kinetic energy transfer, hydraulic system and remote control motor and friction stepless speed change.
● Stress dispersion buffer, dispersion load and mitigation of shock and shock absorption.
Air compressor oil composition
Air compressor oil is mainly divided into mineral base oil and synthetic base oil.
Mineral base oils are widely used and used in large quantities, but in some applications they must be blended with synthetic base oils, thus allowing the development of synthetic base oils to develop rapidly. The mineral oil base oil is refined from crude oil. The additive in air compressor oil is the essence of modern high-grade lubricating oil. The correct choice of reasonable addition can improve its physical and chemical properties, impart new special properties to lubricating oil, or enhance certain properties of air compressor oil components. , to meet higher.
Type and classification of air compressor oil
Air compressor oil can be divided into two types according to the type of base oil: mineral oil type compressor oil and synthetic type compressor oil.
According to the quality and performance of the lubricant requirements, careful selection of additives, careful balance, and reasonable deployment are the key to ensuring the quality of the lubricant. Commonly used additives for air compressor oil components are: viscosity index improver, pour point depressant, antioxidant, detergent dispersant, friction moderator, oil agent, extreme pressure agent, anti-foaming agent, metal passivating agent, emulsifier , anti-corrosion agent, rust inhibitor, demulsifier. Air compressor oil is divided into two types: reciprocating air compressor oil and rotary air compressor oil according to the structure type of air compressor. Each type has three levels of light, medium and heavy load.

Lubrication, cooling, rinsing, sealing, vibration damping, unloading, protection, etc.
Lubricating oil is one of the key accessories in air compressors
Using inferior air compressor oil can cause problems with the air compressor main unit!
Common defects of inferior air compressor oil
1
Poor separation of oil and water, easy to emulsify
2
Poor air release performance, easy to form bubbles
3
Poor wear resistance (four-ball method)
4
Poor oxidation stability
5
Number of particles (NAS) exceeded
