While it is mostly “behind the scenes,” lubrication is used wherever you look—in all types of machines, vehicles, and aircrafts. Its usefulness is everywhere, in every industry, from all types of manufacturing, power, health, petrochemicals, food, paper, and metallurgy to small industries and agriculture. Lubrication is absolutely essential to the world.
There is an undeniable link between maintenance strategy and lubrication reliability. Depending on the industry, maintenance costs can represent between 15-60% of the cost of goods produced. Therefore, the reliability of plant and equipment has a significant impact on the profits of any organization. Unfortunately, most problems related to machinery in plants are lubrication-related. To get maximum benefit from advanced maintenance strategies, an understanding of equipment lubrication is a must. That’s why this work is invaluable.
Machinery Lubrication and Reliability contains everything a maintenance, plant, or industrial professional needs to know about lubrication theory, with vital information on all the critical equipment lubrication requirements. It illustrates how to improve reliability, maximize equipment life, eliminate unscheduled shut downs, and reduce operating costs.
Rounding out this amazing package are questions and answers for those looking to obtain their ICML certifications. An affiliated web site (www.machinerylubricationreliability.com) contains additional questions for exam takers looking for extra practice.
Features The only book that covers all the topics for the ICML certification course. Includes the industry standard API-614 throughout. Contains practice questions for the ICML exam at the end of each chapter, along with additional ones on the affiliated website.

در حالی که بیشتر “در پشت صحنه” وجود دارد ، روغن کاری در هر کجا که به نظر برسید در همه دستگاه ها ، وسایل نقلیه و هواپیماهای هوایی استفاده می شود. سودمندی آن در همه جا ، در هر صنعت ، از انواع تولید ، نیرو ، بهداشت ، پتروشیمی ، مواد غذایی ، کاغذ و متالورژی گرفته تا صنایع کوچک و کشاورزی وجود دارد. روغن کاری برای جهان کاملاً ضروری است.
بین استراتژی نگهداری و قابلیت اطمینان روغنکاری رابطه غیرقابل انکار وجود دارد. بسته به صنعت ، هزینه های تعمیر و نگهداری می تواند بین 60 تا 60 درصد هزینه کالاهای تولید شده را نشان دهد. بنابراین ، قابلیت اطمینان کارخانه و تجهیزات تأثیر بسزایی در سود هر سازمان دارد. متأسفانه بیشتر مشکلات مربوط به ماشین آلات در گیاهان مربوط به روغن کاری است. برای به دست آوردن حداکثر بهره مندی از استراتژی های پیشرفته تعمیر و نگهداری ، درک روغن کاری تجهیزات ضروری است. به همین دلیل این اثر ارزشمند است.
روغن کاری و قابلیت اطمینان ماشین آلات شامل همه چیزهایی است که یک تعمیر و نگهداری ، کارخانه یا نیازهای حرفه ای صنعتی در مورد تئوری روانکاری با اطلاعات حیاتی در مورد کلیه نیازهای مهم تجهیزات روانکاری برخوردار است. این روش چگونگی بهبود قابلیت اطمینان ، به حداکثر رساندن عمر تجهیزات ، از بین بردن تعطیلات غیر برنامه ریزی شده و کاهش هزینه های عملیاتی را نشان می دهد.
گردآوری این بسته شگفت انگیز سؤالات و پاسخ هایی است که به دنبال دریافت گواهینامه های ICML خود هستند. یک وب سایت وابسته (www.machinerylubricationreliability.com) شامل سوالات اضافی برای متقاضیان امتحان که به دنبال تمرین اضافی هستند.
