The 6th edition of the international trade fair EXPOMINA was held from September 12th to 14th in Lima (Peru). Within just a few years this exhibition has developed into one of the largest worldwide and most significant mining trade fairs in Latin America. A comprehensive range of heavy machinery, equipment and services were presented on an exhibition area totaling 47,000 m². Like previous trade fairs the event was again hosted in the Centro de Exposiciones Jockey.
The term ATEX is derived from the French denomination "Atmosphères Explosibles" (explosive atmospheres): The ATEX Standard comprises the Equipment Directive 2014/34/EU as well as the Workplace Directive 1999/92/EC. In a previous article about the ATEX Directive we put more emphasis on general issues and theory. In this article we use the example of a flexible claw coupling to explain in more detail how this standard is implemented in practice.
It’s Oxymoron Day again! And while sitting together to choose the most creative proposals for oxymorons among your submissions, we randomly bumped into interesting facts about group dynamics. Some of them were surprising, some just funny. Therefore in addition to the most favored word pairs: ten facts about teamwork – not only for engineers.
Maintenance is a key factor determining manufacturers’ success since it ensures preferably smooth operation. At the same time service and repair are significant cost factors. We wanted to get a more detailed picture and started researching. Some of the most relevant findings:
Pursuant to the supplement to the Medium Voltage Guideline in 2013, the certification directives for co-generation plants have been adopted and the obligation to furnish evidence of compliance with the BDEW guidelines of 2009 is now also binding for co-generation plants. As a result, certificates have to be furnished for CHPs connected to the medium voltage grid with reference to their behavior in the event of a failure.
An oxymoron connects two contradictory terms. In the field of engineering this often means that the seemingly impossible has become possible. The same holds true for “flexible stiffness”. Learn what it is all about and let us know your personal favorite oxymoron.
The cut-off date has passed. The new EU ATEX Directive is now valid. Manufacturers, distributors and operators should keep themselves informed, since the old certificates are no longer valid for any products that will be newly launched onto the market. There are also amendments pertaining to operators, who themselves set up a plant or an assembly from several components, for example, with a pump, coupling and engine. The user will then be considered as manufacturer and must know the exact properties of the components used, including the coupling.
Locking assemblies and locking elements come in so many sizes and with so many different technical features that it can be overwhelming to find the right one for your application. That’s why we recently developed our online calculation tool that makes it easy to select the right product.
The Ringfeder Rapid Response Program has been up and running for the past several months. Customers have taken full advantage of this program, which makes our most popular metal bellows couplings and shrink disc locking devices available overnight.
