Q:High temperature chain lubrication, with oil or grease?

1. Lubricant:Lubricating oil is a fluid lubricant that is usually used in high-speed rotating parts or in mechanical equipment that operates at high temperatures and high speeds. The main component of lubricant is base oil, and its performance is improved by adding different additives, such as antioxidants, anti-wear agents and rust inhibitors.In high-temperature chain lubrication, choosing the right lubricant ensures that chain surfaces are adequately lubricated, reducing friction and wear.

Advantages of lubricants include:

Good fluidity: the lubricant has good fluidity, which can penetrate into the inner part of the chain quickly and form a uniform lubrication film.

Effective temperature reduction: The lubricant can form a lubricating film on the friction surface of the chain, which helps to reduce the temperature of the chain, minimize heat accumulation and improve the working efficiency of the equipment.

Suitable for high speed operation: The fluidity and lubrication performance of lubricant makes it especially suitable for high speed rotating parts, which can effectively reduce the friction loss.

However, there are some limitations of lubricants in high temperature chain lubrication: High volatility: under high temperature environment, lubricant is easy to volatilize, which leads to lubrication film failure and affects the lubrication effect.Easy to be contaminated: lubricant is easy to be contaminated by external impurities, which reduces its lubrication performance and requires regular replacement and maintenance.

2. Grease:Grease is a semi-solid lubricant composed of base oil and thickener with good adhesion and high temperature resistance.Grease is usually used in heavy load and low speed running machinery and equipment, as well as in high temperature environment where long time continuous lubrication is required.In high temperature chain lubrication, choosing the right grease can effectively protect the chain surface and reduce friction and wear.

The advantages of grease include:

Good adhesion: Grease has strong adhesion, which can form a long-lasting lubrication film on the chain surface, effectively reducing friction and wear.

High Temperature Resistance: Grease usually contains high temperature resistant additives, which can maintain stability at extreme temperatures, not volatile, and maintain long-lasting lubrication.

Waterproof and dustproof: grease has a high viscosity and good waterproof and dustproof performance, which can protect the chain from the external environment.

However, grease also has some disadvantages:Poor fluidity: grease has poor fluidity and is not suitable for lubrication of high speed rotating parts.Difficulty of replacement and cleaning: Once grease is applied to the chain, replacement and cleaning are more difficult than lubricants and require extra maintenance work.
