  • The lubrication of rolling bearings – similar to that of sliding bearings – mainly serves one purpose: to avoid or at least reduce metal-to-metal contact between the rolling and sliding contact surfaces, i.e. to reduce friction and wear in the bearing. Oil, adhering to the surfaces of the parts in rolling contact, is fed between the contact areas. The oil film separates the contact surfaces preventing metal-to-metal contact (»physical lubrication«).

  • 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.

  • Machinery reliability management in the process industries can be divided into three phases: equipment selection and pre-erection reliability assurance, preparation for effective startup, and post-startup reliability assurance and maintenance cost reduction. All of these phases are important; they are intertwined and merit equal attention. The techniques and procedures described in this text cover essential elements of each phase; they have been critically examined and have led to substantially improved reliability and maintenance efficiencies.

  • A further check on the refrigerant charge is described on pages 33 8. When vapour charging a system with an azeotropic refrigerant such as R502 the refrigerant cylinder must always be kept in a vertical position to prevent the possibility of liquid refrigerant from entering the compressor. This can create a dynamic pressure when the compressor starts, causing damage to valves or may even break piston connecting rods and damage pistons. The liquid refrigerant will also flush lubricating oil from bearing surfaces.

  • VACUUM DISTILLATION TOWER In order to further distill the residuum from the atmospheric tower at higher temperatures, reduced pressure is required to prevent thermal cracking. The process takes place in one vacuum distillation tower. The principles of vacuum distillation resemble those of fractional distillation and, except that larger-diameter columns are used to maintain comparable vapor velocities at the reduced pressures, the equipment is also similar.

  • This publication presents design examples covering various machines, vehicles and equipment having one thing in common: rolling bearings. For this reason the brief texts concentrate on the rolling bearing aspects of the applications. The operation of the machine allows conclusions to be drawn about the operating conditions which dictate the bearing type and design, the size and arrangement, fits, lubrication and sealing. Important rolling bearing engineering terms are printed in italics. At the end of this publication they are summarized and explained in a...
