Description

Technical Field

[0002] Graphene lubricant is a new type of high-performance lubricant. It is made by adding graphene materials to traditional lubricants. With the continuous advancement of science and technology and the increasing demand for high-performance lubricants, graphene lubricants have broad development prospects.

[0003] Traditional lubricating oil heating devices often cannot meet the special needs of graphene lubricants. Ordinary heating methods are prone to local uneven heating during the heating process. Due to the lack of an effective stirring mechanism, the lubricating oil is prone to form local static areas in the container, which will affect the dispersion of graphene in the lubricating oil, making the local graphene concentration too high or too low, thereby reducing the lubrication effect. In addition, the stability and sustainability of the heating process are also problems that need to be solved urgently. Traditional heating devices lack a complete heating medium circulation system, making it difficult to accurately control the heating temperature and heat transfer efficiency. The heating medium cannot be heated evenly in the liquid storage tank, which will cause unstable heat supply, and it cannot ensure uniform temperature rise when transferred to the graphene lubricant, resulting in large fluctuations in the lubricating oil temperature.
