What are the functions of lubricating additives for spring machine equipment?

Spring machines are the same as our industrial equipment. Routine maintenance must be done. Therefore, it is necessary to learn to apply lubricating additives, distinguish the role of different additives, and reasonably improve the application and lubrication level of the spring machine. Let's share the role of lubricating additives for spring machine machinery.

The effect of lubricating additives on spring machine equipment:
⑴ cleaning thickener. Detergent thickener is used to synthesize acid-base compounds produced by oil oxidation, prevent acid-base compounds from deepening oxidation, digest and absorb particulate matter in compounds, and make them dispersed in oil. Therefore, the conversion of the paint layer can be inhibited, and the converted carbon deposits and paint-like substances can be removed from the stainless steel passivation layer without scaling or accumulation on the stainless steel passivation layer of the spring machine. This detergent thickener is this antioxidant, anti-corrosion, anti-wear, multi-effect additive. Mainly used for gas turbine oil, the current consumption accounts for about 50% of all lubricating oil additives.

⑵ Antioxidant additives. Antioxidant additives prevent fuel oxidation and mildew. Adding antioxidants to grease can reduce the amount of CO2 absorbed by fuel, thereby greatly reducing the conversion rate of acid-base compounds produced by grease and oxygen, preventing redox reaction, and improving the service life of fuel. Aviation hydraulic oil, turbine oil, Antioxidants should be used in greases that work at medium and low temperatures, such as gear oil and instrument panel oil.

⑶ Tackifier. Tackifiers added to oils can affect the viscosity of the grease. As the temperature increases, the molecular structure of the tackifier "stretches", preventing a reduction in the viscosity of the grease. When the temperature is lower, the solubility of the tackifier decreases, and the molecular structure just begins to "curl" into small inseparable clusters, so it has little effect on the viscosity, and the viscosity of the grease is at ultra-low temperature.

⑷ Oil-soluble additives. Oil-soluble additives are used to improve the wetting properties of finished oils during boundary friction, maintaining minimal damage and low friction effects. These additives are all polar molecules, which are fixed and adsorbed in the metal material to rub the surface layer to produce a firm oil film. The product oil is not easy to destroy the oil film under high working pressure, which improves the actual effect of extreme lubrication. Oil-soluble additives are usually used for extreme lubrication, but not for extreme pressure lubrication.

⑸ Extreme pressure additives. The key to extreme pressure additives are organic chemical optically active compounds containing sulfur, phosphorus and chlorine. These compounds are not lubricating at room temperature. At high pressure and temperature, they passivate with the stainless steel of the compression spring, resulting in a relatively strong composite film. Its melting point is lower than that of metallic materials. When the surface of the spring machine increases in temperature due to friction, this composite film melts and transforms into a smooth surface that reduces friction and damage. In addition, common additives include anti-rust treatment additives, pour point depressants, defoamers, antioxidants and anti-corrosion additives.
