As one of leaders of common mechanical failure in industrial mills industry, SBM always seeks innovation & excellence.
Failure Mode: Lack of a Strategy for Managing Equipment Even though condition-based monitoring methods may be established, strategies for managing equipment are still needed. Condition monitoring is a requirement for good machine management, but other strategies also should be incorporated into the equipment reliability process.

The rotating stall phenomenon is very common in centrifugal and axial‐flow compressors and may also occur in pumps when the flow rate is much lower than the normal capacity. Pump vibration is one of the serious problems that can result in complete failure of one or more of the pump components. The severity of mechanical vibrations can be ...

This article lists notable industrial disasters, which are disasters caused by industrial companies, either by accident, negligence or incompetence. They are a form of industrial accident where great damage, injury or loss of life are caused.. Other disasters can also be considered industrial disasters, if their causes are rooted in the products or processes of industry.

Among the most common causes of electrical faults are these: Components that burn out or wear out easily, such as fuses, relay contacts, light bulbs, and mechanical switches are a major cause of malfunctions. Fuses, by the way, tend to burn out because there is a problem so don't just change the fuse without also resolving the problem.

Dec 17, 2011· The normal outcome of such an arrangement is a consistently frequent failure of the mechanical seal or bearing (when packing is fitted) at the end of the shaft closest to the suction source. Such failure will normally occur at approximately 6-month intervals regardless of the type of seal or bearing installed. Undersized Shaft in an End Suction ...

composite exhibit a wide variety of failure mechanisms. However, a common feature of these diverse materials is their inhomogeneous and frequently markedly anisotropic nature, resulting in fracture behaviour unlike that of conventional metallic alloys. As a result, current fracture mechanics based analyses and test procedures are often

Mechanical wear occurs when machine surfaces mechanically wearing against each other. Abrasive wear is a method in which particle contamination causes the majority of the wear. Particles such as dirt or wear debris can lead to three-body abrasion or surface fatigue, which results in the surfaces becoming pitted and scored.

There are many aspects to consider when selecting an industrial motor, such as application, operational, mechanical, and environmental issues. Generally speaking, the choice is among an ac motor, a dc motor, or a servo/stepper motor. Knowing which one to use depends on the industrial application and if there are any special needs required.

of failure is available in the vibration signal. The design life of a bearing is very dependant upon the service it is in. In some industries it appears that fewer than 5% of bearings achieve their design life. Primary Causes of Premature Bearing Failure The most common cause of bearing failure is probably loss or contamination of the lubricant.
