  • Maintenance costs, as defined by normal plant accounting procedures, are normally a major portion of the total operating costs in most plants. Traditional maintenance costs (i.e., labor and material) in the United States have escalated at a tremendous rate over the past 10 years. In 1981, domestic plants spent more than $600 billion to maintain their critical plant systems. By 1991, the costs had increase to more than $800 billion, and they were projected to top $1.2 trillion by the year 2000.

  • This book addresses, in a simplistic manner, the proper principles and techniques in “Best Maintenance Practices—Mechanical.” If these principles and techniques are followed, they will result in a serious reduction in “self-induced failures.” This book is a tool that should be carried and referenced by all mechanical maintenance personnel. A number of surveys conducted in industries throughout the United States have found that 70% of equipment failures are self-induced.

  • The article deals with a research on the design and manufacturing of a dynamic balancing machine, using dynamic load sensors and optical one, for calculating the unbalanced mass in thick rotating part on two choosen correction planes. Dynamic load sensors attached to the bearing supports of the machine help us determine the reaction forces generated by the unbalanced mass of the rotor. These load signals are filtered and digitized at a sampling rate which is synchronous to the rotor via an optical sensors.
