Lubricating gears with synthetic OiLs
wind gearbOx technOLOgy is developing at a fast pace, not least due to operators demanding ever more power and efficiency. Experience has shown that the lubricant used is a crucial factor in meeting the wish for ever-increasing performance. Besides strictly technical requirements, aspects of economy and ecology are receiving more and more attention in lubricant selection. The technical requirem...
متن کاملThe Re-refining of Used Lubricating Oils
Re-refined lubricants have been produced in New Zealand for over 50 years. However, their acceptance as a high quality lubricant has been a gradual process, largely because of the scepticism of the public that the product can be re-refined to its original condition. In New Zealand Dominion Oil rerefines about 7 million litres per year, while an older acid clay method is used at Turua near Thame...

ترانسفورماتورهای قدرت از اجزای اصلی شبکه تامین انرژی الکتریکی می باشند که عملکرد قابل اطمینان ترانسفورماتورها یکی از فاکتورهای مهم و تعیین کننده در تامین انرژی الکتریکی محسوب می شود. در نتیجه بررسی و مانیتور عملکرد ترانسفورماتورها در شبکه و همچنین عیب یابی این ترانسفورماتورها غیرقابل اجتناب و ضروری می باشد. به طور کلی عایق های مایع در صنعت فشار قوی کاربردهای متفاوتی دارند که مهمترین وظیفه آنها...

متن کاملEco-Friendly Multipurpose Lubricating Greases from Vegetable Residual Oils
Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...
