Machine Reliability

Abstract

The process of management of machine reliability in the industries can be divided in to three categories. First, are the pre-erection reliability and the selection of equipment? Second, is the preparation for an effective start up? Final, is the maintenance cost reduction and assuring the post start up reliability. These all phases are of immense importance, as they are intertwined together and require equal attention. In this research paper we will provide the techniques and procedures which play an essential role in improving the reliability of the machines inside the industry, as an adaption of effective procedures and techniques in the industry results in an improved profits and growth for the industry.

Problem Identification

Machine design in the industry these days tends to be of larger, more complex and higher productivity. Moreover in the mining industry where large amounts of material extracted, transported and processed require huge machines that meet the various work required to obtain mineral. Being larger downtimes of a unit generated a great loss of production with high maintenance costs. This has led to a change in maintenance strategies, evolving from the pattern of periodic inspections and operating a scheme based on conditions specific to a predictive maintenance plan. Furthermore, it is urgent sustainable solutions in time to respond to maintenance strategies safe and reliable, low cost in order to respond to expected changes in the Chilean mining horizon (ADAS, 1989, p.61-89).

The predictive maintenance strategy is a viable solution to increase the intervals in the planning of repairs and maintenance. Machinery repairs are made only when the analysis of some recorded values ??indicate that it is absolutely necessary. The early detection of failures also reduces the number of auxiliary components in the inventory of maintenance because it has enough time to order parts to be replaced (ADAS, 1989, p.61-89). Predictive maintenance uses in its purpose several high-tech equipment personnel with specific knowledge and operating history of the machines that should be examined to determine their condition. Nondestructive techniques most commonly used in predictive maintenance are: vibration analysis, infrared thermography, temperature analysis, oil analysis and magnetic particles, analysis of electrical current, and ultrasound analysis for either fault detection , cracks or thickness measurement.Also included are liquid penetrant and industrial radiography, as well as numerous essays electrical partial discharge, insulation resistance and polarization index, frequency response tests for magnetic circuits, and physico-chemical tests such as chromatography and furfuraldehídos only to name a few types of electrical testing. Of all these techniques, measurements and subsequent analysis of the vibrations have proved the most versatile and important ...
