5 days LUB/LUBEI-E
- Engineers and technical staff involved in the recommendation and the use of lubricants in industrial equipment, their maintenance and the identification of the origin of the equipment failures.
- This course provides a deeper knowledge on the material and equipment to the non-mechanical people for a better understanding of the role of the lubricant. It presents the essential properties of lubricants depending on the equipment and their operating conditions.
- Upon completion of the course, participants will be able to:
- describe the different mechanical organs and machines used in the industry,
- explain the role and the importance of the standardization in the field of lubrication and lubricants,
- explain the mode of action of the lubricants and the properties required for a given application,
- recommend a lubricant according the equipment and its operating conditions,
- detect the origin of the equipment failures,
- select a lubricant for a given equipment
- analyze lubricants in use.
- In order to maximize the benefits of this training course, it is strongly recommended to initially follow the training course entitled “Lubrication and Lubricants”.
Ways and means
- Interactive exercises with the teacher will be conducted to determine the lubricant to be used based on the technical data of the equipment and its operating conditions.
- Interactive exercises of questions-answers between the participants using sets of play cards to synthetize the essential points of the lectures.
