Application of oil-free bearings in the lubrication of key industrial and mining equipment
Due to the requirements of the production process, some key equipment of industrial and mining enterprises operate under extremely severe working conditions. Due to the heavy equipment and high ambient temperature, the dust is large or the air contains acidic corrosive gases such as CO and SO2, which brings many problems to the lubrication of the equipment. The friction and wear are serious. So far, most of the above-mentioned enterprises in China still use traditional oil. Grease lubrication, and in fact these industrial and mining conditions have exceeded the range of oil and grease lubrication, and it is prone to bite or seizure of bearings and other friction pairs, causing serious wear and damage of parts, which often leads to equipment outage. In order to produce continuous operation, in addition to the original design required to install multiple equipment wheel repair, a large number of maintenance personnel must be invested. Seriously limiting productivity, spare parts and energy consumption have become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have proposed the provision of special lubrication materials under complex working conditions. To this end, oil-free bearings solve the lubrication problem under special working conditions for enterprises, and bring obvious economic and social benefits.
