An automated monitor provides a live, continuous picture of exactly what is happening inside a turbine for protection, prediction, performance monitoring, and integration of the data with process control.
It is easy to confuse graphite fiber packings with carbon fiber packings. In fact, the terms carbon fiber and graphite fiber are often used interchangeably, even by packing manufacturers. Both products are used to manufacture braided packings, and they both have relatively good chemical and temperature resistant properties. But there are differences, and each has its advantages and disadvantages.
In the foothills of the Andes, among the sprawling vineyards of picturesque Mendoza, Argentina, stands an innocuous equipment cabinet located by the side of an infrequently used mountain pass. The cabinet's superficial surface rust belies its importance as one of the most significant technological developments in modern day corrosion prevention. The cubicle, battered from years of an abrasive cocktail of arid Patagonian winds and coarse earth, hides the cradle of a revolutionary approach to cathodic protection. The equipment within the cabinet resulted in an entirely new range of products.
Whoever coined the phrase "Don't sweat the small stuff" was likely not an engineer. Everything engineers do is ultimately defined by the success of "the small stuff" that comprises the larger design projects.
Use of disposable components in product downstream processing and final fill operations is increasing as technology improves for performing these steps in a single-use mode. There is a high demand for systems that support single-use purification, formulation and filling operations.
It required only a couple notes of the haunting soundtrack to signal an imminent shark attack in the movie Jaws. As the theme began to swell, it became obvious that someone was going to “get it.” It would be nice to have a sixth sense that allowed us to hear "warning" music in daily situations. Condition monitoring systems provide a means of sensing when sharks are skulking toward your critical machines.
Most shaft seals are typically placed in bores made of steel, cast iron or other common ferrous metallic material. These ferrous, or iron-containing materials, are compatible with both metal cased and rubber covered seals.
Last year in “Trending Revelations in Vibration Analysis,” (Pumps & Systems, June 2009), I discussed the importance of statistic trending in vibrations analysis. Usually, as most would expect, vibrations gradually increase with time. This increase reflects the normal internal wear, accumulative misalignment and deformations that can occur within a pump. All these wear conditions will lead to eventual failure.
