Dry disconnect couplings from Dixon Group Europe are designed for quick and spill-free connection and disconnection of hoses and pipelines.
Steve Cupples, managing director of Industrial Purification Systems (IPS), together with John A Lewis, microbiologist and group director of Waterman Environmental Group, and Chris Mutch, managing director of M & S Water Services and M & S Water Services (Envirotec), discuss why industry is still prepared to accept a poor quality of process water filtration, the risks of not doing so and why advanced media filtration technology is the answer.
Hydraulic motors and pumps are used in a variety of environments. These environments can be damaging to shaft seals due to dirt particles penetrating the shaft sealing area. This will begin to erode the elastomer, altering the shaft surface finish in the sealing area, and seal failure will eventually occur. Replacing the seal requires removing the pump/motor, disassembling and repairing it and reinstallation. The result? Significant system downtime increasing operating expense.
According to Peter Swanson, managing director at Intertronics, the lubrication of mechanical and electromechanical assemblies should be a precise science, with applied material volume and placement accuracy critical to effectiveness. No one expects the control buttons in their car to leave grease on their fingers. Operators of precision equipment do not expect to find their parts contaminated by lubrication from the bearings.
According to Dixon Group Europe, it is important to identify the threads required before ordering couplings. Identifying threads can sometimes be the most difficult and frustrating part of coupling selection. However, without the right combination of threads, you may not provide a functional or safe connection.
Where once it was believed that design would always be predicated on the need to take things apart and repair of recycle them, the fact is that the opposite has increasingly become true. As this article from TR Fastenings explains, electronic devices, in particular, have seen a fundamental shift whereby disposability is increasingly considered the norm — even in expensive devices.
In this interview, Malcolm Diamond, executive chairman of Trifast, whose Sussex-based trading arm TR Fastenings manufactures and distributes industrial fastenings and associated components, discusses different markets, the factors underpinning the company’s growrth and opportunities on the horizon.
Dr Louis Raymond is a materials scientist with more than 30 years’ experience as consultant, educator, diagnostician and forensic scientist. Here, he answers frequently asked questions related to the cause of fastener failures.
One of the most common needs in engineering is to join two or more parts together. Usually, the main requirement is for a secure and long-lasting bond, although the ability to undo the joint at will is not uncommon. Here, John Marshall, technical engineer at WDS Component Parts, reviews the relative merits of various fastener and adhesive options.
