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.
Measuring processes unconsciously cross our daily paths more often than we are aware. Whether it is about scooping coffee for the coffee maker, the temperature of the coffee or the speedometer in a car - we encounter measurement technology everywhere. But, what is “measuring”?
A well suited definition is given here: “Measurement enables us to make statements about a measured parameter in relation to a unit of measurement”. Measurement technology allows the determination of parameters such as length, mass, temperature etc.
Since 1993 the annual exhibition and conference for the European energy industry presents new developments on the topics such as renewable energies, power plant technology as well as distributed energy generation. Since then the Power-Gen is deemed to be the leading trade fair for the power technology and energy industry in Europe, which takes place at changing locations every year. For the 25th issue of this trade visitor fair with its accompanying internationally oriented congress, organisers PennWell (UK) selected Cologne (Germany).
Gas turbines are available in many different designs and the power output of the individual models varies considerably – from 200 kW to more than 400 MW. The performance of gas turbines for industrial applications typically ranges from 5 to 40 MW. Dependent on the power, the speeds vary from 3,000 rpm to 15,000 rpm. Please see below which couplings are typically used and which are the selection criteria.
The presentation for the customer, performing at an exhibition or an internal meeting: again and again engineers have to face the challenge to present their developments. This isn’t everybody’s job. A frequent obstacle: preparing a PowerPoint presentation eats up time – and in the end it does not look that professional in many cases. The following basic tips should change that!
Designers of plants and machines strive for the optimal selection of a coupling for the complete system with many variables requiring consideration. In most cases the main focus is not how maintenance-friendly the product is. Yet – one might say. For a sustainable improvement of the longevity and efficiency of plants, a stronger involvement of maintenance is a must.
The Hannover Messe starts on April 24, 2017, and we are again excited to see what awaits us. There is one specific topic that stands in the foreground: The lead theme of the Hannover Fair this year is “Integrated Industry – Creating Value”.
Without question, engineers have to deal with many important tasks in their daily life. Their responsibilities are always being extended with everything a top priority which increases time pressure: more and more projects need to be handled with increasing demands in less time but stable quality. In addition, smartphones, tablets and notebooks are pinging and blinking continuously. How is it possible to use working time efficiently despite these facts?
Topics as varied as Big Data, Industry 4.0, Digital Transformation, Crowdworking, Generation Y , Work 4.0 and 3D-printing have been discussed in 2016, and many of these will have significant influence on the working world over the next few years. This also applies to mechanical engineering. We would like to refer to three terms that have gained importance in 2016.
