Knowledge summary of air compressor lubricants

Air engine oil is what we usually call air compressor lubricating oil. Next, we mainly introduce the relevant knowledge of air compressor oil.

The use of air compressor oil

Air compressor oil is used in various types of machinery to reduce friction and protect the liquid lubricant of machinery and processed parts. It is mainly used for lubrication, cooling, rust prevention, cleaning, sealing and buffering. Air compressor oil accounts for 85% of all lubricating materials. There are many types and brands. The world's annual consumption is about 38 million tons.

Air compressor oil use 1: reduce friction and wear resistance, reduce friction resistance to save energy, reduce wear to extend mechanical life, and improve economic benefits

Air compressor oil use 2: cooling, requiring frictional heat to be discharged out of the machine at any time

Air compressor oil use three: sealing, requiring anti-leakage, dust-proof, and anti-channeling

　The fourth use of air compressor oil: clean and flush, it is required to clean the friction area and remove it.

Air compressor oil use five: anti-corrosion and anti-rust, and it is required to protect the friction surface from oil deterioration or external erosion.

Sixth use of air compressor oil: kinetic energy transmission, hydraulic system, remote control motor and friction stepless speed change.

Seven uses of air compressor oil: stress dispersion buffer, load dispersion and shock mitigation and shock absorption.

Air compressor oil composition

1. Air compressor oil composition lubricating oil base oil

2. Lubricating oil base oil is mainly divided into mineral base oil and synthetic base oil. Mineral base oils are widely used and used in large amounts, but in some applications, products formulated with synthetic base oils must be used, which has led to rapid development of synthetic base oils. Mineral oil base oil is refined from crude oil. The main production process of air compressor oil component lubricant base oil includes: atmospheric and vacuum distillation, solvent deasphalting, solvent refining, solvent dewaxing, clay or hydrogenation supplement refining. The chemical composition of mineral base oils includes high boiling point, high molecular weight hydrocarbons and non-hydrocarbon mixtures. The composition of air compressor oil is generally alkanes, cycloalkanes, aromatics, cycloalkyl aromatics, and oxygen-containing, nitrogen-containing, sulfur-containing organic compounds and non-hydrocarbon compounds such as gums and asphaltenes.

3. Saman air compressor oil component additives are the essence of modern high-grade lubricants. The correct selection and reasonable addition can improve their physical and chemical properties, impart new special properties to the lubricant, or enhance the original components of the air compressor oil. Certain performance meets the requirements of higher screw air compressor oil types. According to the required quality and performance of lubricants, careful selection of additives, careful balance, and reasonable deployment are the keys to ensuring the quality of lubricants. Commonly used additives for air compressor oil components are: viscosity index improvers, pour point depressants, antioxidants, detergents and dispersants, friction reducers, oiliness agents, extreme pressure agents, antifoaming agents, metal deactivators, emulsifiers , Anti-corrosion agent, anti-rust agent, demulsifier.

4. Classification of air compressor oil

5. Air compressor oil is divided into reciprocating air compressor oil and rotary air compressor oil according to the structure of the compressor, each of which has three levels of light, medium and heavy load. Air compressor oil can be divided into mineral oil compressor oil and synthetic compressor oil according to the type of base oil.

6. Air compressor oil is mainly used for the lubrication of the moving parts of the compressor cylinder and the exhaust valve, and plays a role of rust prevention, corrosion protection, sealing and cooling. Since the air compressor is always in an environment with 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 separability, rust and corrosion resistance, etc.

7. The role and main performance of air compressor oil

Suitable compression medium for air compressor oil Suitable compression medium for air compressor oil includes air; various hydrocarbon gases (such as natural gas, petroleum gas, coke oven gas, ethylene, propylene, propane, etc.); inert gas (such as hydrogen, nitrogen) , Carbon dioxide, carbon monoxide and argon, neon, helium, etc.); reactive gases (such as chlorine, hydrogen chloride, nitrogen oxide, sulfur dioxide, etc.).
