Introduction to reliability

Introduction to reliability (Portsmouth Business School, April 2012) 2 After this, the reliability, R(t), will decline as some components fail (to perform in a satisfactory manner). The failure rate The failure rate (usually represented by the Greek letter λ) is a very useful quantity. This is defined asGet price

Determining the Reliability of - Machinery Lubrication

The Properties of GreaseSingle-Line Injector SystemsDual-Line SystemsSingle-Line Progressive SystemsMulti-Line LubricatorsSingle-Point LubricatorsReliability of Automatic Lubrication Systems – A General ViewGreases, because they are Non-Newtonian (where the viscosity is not constant over a whole range of shear stresses and rates), do not have a viscosity, but instead have an apparent viscosity classified by an ASTM worked-penetration number corresponding to an NLGI consistency number (National Lubrication Grease Institute), as shown in Figure 1. Figure 1. Apparent Viscosity Chart for Greases The grease has to be carefully selected to deal with the operating condition of the plant to which it is being applied and its ability to work properly within a centralized lubrication system. Greases have two special properties that must be considered when used in an automatic lubrication system: separation and internal flow resistance. Grease consists of a physical matrix containing an oil, thickener and additive package. During the operation of a centralized system, when grease is passed through a restrictor or dispensing valve, the oil may, if not selected carefully, separate from the thickenin...Get price

Reliability Engineering Principles for the Plant Engineer

Reliability Engineering HistoryWhat Is Reliability Engineering?Basic Mathematical Concepts in Reliability EngineeringThe ‘Bathtub’ CurveThe Multi-Slope Weibull PlotEstimating System ReliabilityThe origins of the field of reliability engineering, at least the demand for it, can be traced back to the point at which man began to depend upon machines for his livelihood. The Noria, for instance, is an ancient pump thought to be the world’s first sophisticated machine. Utilizing hydraulic energy from the flow of a river or stream, the Noria utilized buckets to transfer water to troughs, viaducts and other distribution devices to irrigate fields and provide water to communities. If the community Noria failed, the people who depended upon it for their supply of food were at risk. Survival has always been a great source of motivation for reliabilityand dependability. While the origins of its demand are ancient, reliability engineering as a technical discipline truly flourished along with the growth of commercial aviation following World War II. It became rapidly apparent to managers of aviation industry companies that crashes are bad for business. Karen Bernowski, editor of Qualit...Get price

System Reliability Availability Calculations – BMC Software

What Is Reliability?What Is Availability?Incident & Service MetricsCalculation of Multi-Component SystemsAdditional ResourcesRelated ReadingReliability is the probability that a system performs correctly during a specific time duration. During this correct operation: 1. No repair is required or performed 2. The system adequately follows the defined performance specifications Reliability follows an exponential failure law, which means that it reduces as the time duration considered for reliability calculations elapses. In other words, reliability of a system will be high at its initial state of operation and gradually reduce to its lowest magnitude over time.Get price
