The oil film bearing in rolling mill lubrication management

1. To carry out full excellent lubrication management of the oil film bearing in rolling mill, according to incomplete statistics about the present situation of domestic oil film bearing of unusual sexual friction losses more than 80% are due to the oil film bearing oil or oil film bearing lubrication system fault or improper use, particularly with the solid particles of pollution in the lubricating oil, water and oil of metamorphism. How to improve the lubrication maintenance technology to improve equipment reliability, reduce the maintenance cost of equipment, the purpose of this is the full excellent lubrication management. Full excellent lubrication is a new concept, in the United States is called a revolution in the field of machinery lubrication. It challenges the people over the years, the traditional concept and practice, therefore to implement full excellent lubrication management helps to shift people's point of view. Abroad in recent years is very pay attention to the idea of full excellent lubrication management propaganda, technical education and training, and led to a number of small, highly specialized training and consulting firm specializing in full excellent lubrication management concept, developed a series of training materials. Proved that effective training is the prerequisite for promotion and application of full excellent lubrication management, at the same time this kind of training from the leadership of the enterprise decision-makers, equipment and lubrication management of the high-level leadership, equipment and lubricating management or technical backbone to the equipment maintenance and condition monitoring of engineering and technical personnel, operators, all full excellent lubrication management strategies and practice training. Foreign big companies invested to develop its own series of training materials and planning, for example BKP - Billiton, the world's largest mining company resources on the development of its own series of training materials, has hundreds of lubrication on the company professionals provides roughly 30 ~ 60 class hours each full-time full excellent lubrication technical training. Currently Shanghai runhai firms are also actively carry out the training and promotion, in domestic has paid off. Understanding of lubricating maintenance technology is the first step of change. Training is the second step of lubricating maintenance technology. Through to the enterprise actual working condition of production and special equipment, a comprehensive study of lubricating oil suppliers and manufacturers of lubrication training, establish a lubricant prevention and control of the detection system, which is the core content of full excellent lubrication technology. It includes enterprise applications related to lubrication standard, institutionalized optimal lubrication maintenance procedures, set up comprehensive analysis system and independent inspection system, guarantee to the end user to provide accurate and reliable results, through the actual sample analysis, the lubricants and lubrication equipment comprehensive evaluation, recommends the management mode of lubricant on the spot, the best sampling method, optimized lubrication measures and specific conditions limit, etc. Oil film bearings are key components in steel rolling machinery, attaches great importance to deal with lubrication monitoring. According to the statistics and the famous fluid pollution and life-cycle theory, such as the purity of the oil film bearing lubricating oil from 18 to ISO16 ISO21 / / 13 ( NAS7 level) And the life of the bearing can improve nearly three times, the latest of the purity of the oil film bearing lubricating oil for a period of 12 (ISO15 / NAS6 level) , before our country never very attention to the purity of the oil film bearing lubricating oil, the oil film bearing in rolling mill has been using metal mesh filter, such filter filtration precision less than standard of cleanliness, visible from the oil film bearing and the industrial development of rolling bearing gap. It is proved by optimizing the implementation of the lubrication,
