Special production process
Due to the requirements of special production technology, some key equipment of industrial and mining enterprises run under extremely bad conditions. Due to the heavy equipment, high temperature, dust or air containing acid corrosion in gas CO, SO2, etc., bring many problems of equipment lubrication, friction and wear serious, most of the domestic enterprises is still using the traditional oil, grease, and the fact that the industrial and mining condition is beyond the scope of oil, grease, easily happened bearing and other friction pair of bite or bite dead, Causing severe wear and tear to parts, frequently resulting in equipment outages.
In order to produce continuous operation, in addition to the original design required the installation of multiple equipment wheel repair, also need to invest a large number of maintenance personnel. Seriously restrict the improvement of productivity, spare parts and energy consumption, has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have put forward the requirements of special lubricating materials under complex working conditions.
Therefore, the research on inlaid self-lubricating composite material highlights its own characteristics in material formulation and preparation process, and the material performance has reached the international advanced level, which solves the lubrication problem under special working conditions for enterprises, and brings obvious economic and social benefits. But for a variety of reasons more domestic enterprises have not adopted, the situation still exists.
Key Technical Principles
The composite material used for inlaid self-lubricating bearing is a new type of extreme pressure resistant solid lubricating material, which is composed of metal substrate and solid lubricant paste embedded in the hole or groove of the substrate. In the friction process, the metal substrate bears most of the load. After the friction, the solid lubricant in the hole or groove transfers to the friction surface or reverse transfer, forming a solid transfer film with good lubrication, firm adhesion and uniform coverage on the friction surface, greatly reducing the friction and wear. As the friction goes on, the solid lubricant embedded in the friction surface is constantly provided to ensure the good lubrication of the friction pair during long-term operation.
