Book Synopsis Etude de la durée de vie des contacts sous-alimentés en lubrifiant by : Emmanuelle Querlioz
Download or read book Etude de la durée de vie des contacts sous-alimentés en lubrifiant written by Emmanuelle Querlioz and published by . This book was released on 2007 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: La compréhension et la maîtrise des phénomènes de la lubrification des contacts a un impact direct sur le fonctionnement des mécanismes. La sous-alimentation en lubrifiant réduit l'épaisseur de film dans le contact et provoque des défaillances anticipées. Elle modifie aussi le frottement dans les contacts, ce qui augmente les pertes d'énergie. L'étude expérimentale du coefficient de frottement montre qu'il dépend fortement des conditions d'alimentation. Dans le domaine sous-alimenté, le frottement n'est pas constant et un certain nombre de cycles est nécessaire avant de parvenir à un fonctionnement stabilisé. Il s'agit du temps nécessaire pour équilibrer les pertes de lubrifiant et la réalimentation autour du contact. Une augmentation de la vitesse ou de la viscosité rend la sous-alimentation plus sévère. Les mesures de coefficient de frottement dans les contacts sous-alimentés sont utilisées afin de déterminer l'épaisseur du film de lubrifiant. Cette méthode permet la détermination expérimentale des épaisseurs de film de lubrifiant. Cette méthode permet la détermination expérimentale des épaisseurs de film dans les mécanismes complets. La durée de vie des contacts sous-alimentés est étudiée théoriquement et expérimentalement. L'influence de la réduction du débit de lubrifiant est non négligeable. Les réductions observées peuvent aller jusqu'à plus de 50%. Globalement, l'importance des dissipations thermiques dans les contacts sous-alimentés est mise en évidence. La plage de conditions de fonctionnement dans laquelle la sous-alimentation peut être observée est très réduite. Le passage d'un contact suralimenté à une défaillance par grippage se fait très rapidement.
Book Synopsis Iodine and Inorganic Iodides by : J. Risher
Download or read book Iodine and Inorganic Iodides written by J. Risher and published by World Health Organization. This book was released on 2009 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Iodine is a naturally occurring element and inorganic iodines found in the ocean accumulate in fish, shellfish and seaweed. Industrially iodine is used in many applications including the manufacture of inks, dyes, photographic agents and in water-purification. In the health-care industry, iodine is widely used as a disinfectant/biocide and in the production of soaps, bandages, and medicines. Iodine is also included as a salt in some countries to provide dietary supplementation. This Concise International Chemical Assessment Document (CICAD) evaluates the scientific literature on the health aspects of iodine and inorganic iodides. Its focus is on the health effects from environmental exposures beyond those associated with the diet and nutritional supplementation. Radioactive iodine isotopes are regarded as outside the scope of the document.
