Self-healing adhesives Researchers at Oak Ridge National Laboratory (Oak Ridge, Tenn.; www.ornl.gov) developed a series of autonomous self-healable and highly adhesive elastomers that are fabricated via a simple, efficient and scalable process. The self-healing elastomers demonstrated unprecedented adhesion strength and…
This company’s Cooper split spherical roller bearings (photo), available in open or sealed configurations, are designed for easy replacement with little disturbance to the shaft alignment or driveline and eliminate the need to remove attached equipment. This bearing solution increases…
Thermal oxidizers are pollution-control units designed to prevent process-generated volatile organic compounds (VOCs) from entering the environment. Different technologies offer tradeoffs among initial cost, operating expense, complexity, emissions, fuel efficiency and destruction efficiency. This one-page reference provides information on selecting…
Niagara brand vibrating-screen exciters (photo) are offered in four models, each of which is adjustable to provide eight weight configurations, delivering a large static-moment range. These exciters come standard on all of this company’s exciter-driven XL-Class and L-Class vibrating screens,…
Waterhammer arises because of sudden changes in fluid flow, and can present significant problems in processes that involve flowing liquids. This article outlines these potential issues and offers guidance for handling the pressure changes arising from waterhammer Most large-scale processes…
This pictorial guide illustrates some of the common problems that can occur with polymeric and elastomeric materials that differ from those that occur with metallic seals and components Failures of polymer (plastic and elastomeric) parts and their consequences can be…
This overview compares various sealing technologies, and points out advantages and disadvantages of applying different mechanical-sealing designs for caustic fluids Caustic applications in chemical plants can play havoc on the mechanical seals of rotating equipment. These applications can be difficult…
