Everything under control with AdaptShield DVP Vacuum Technology will introduce the new CBL Systems with the AdaptShield technology at IFFA 2019, Frankfurt am Main, from 4 to 9 May. AdaptShield is a new device that optimally manages the functioning of CBL systems by guaranteeing the automatic protection of the BCA lobe pump and the primary lubricated pump in case of critical events such as plant leaks, loss of performance and over temperature. Due to the self-adaptive control, AdaptShield is claimed to be able to optimise the absorbed energy according to system conditions, with energy savings of 13% compared with systems without AdaptShield, and 20% compared with those with mechanical bypass. According to DVP Vacuum Technology, AdaptShield ensures improved performance: shorter pump down time, fast reaction to pressure variation and optimal adaptation to the process to enable the best possible performance. The use of the new CBL Systems with AdaptShield is easier due to the plug and play installation and the fast sizing software to meet every need. DVP Vacuum Technology comments that everything is under control with AdaptShield, even from a smartphone with the app that monitors the operating parameters, error individualisation and remote support. www.dvp.it Ultrasound is an acoustic vibration frequency too high to be audible. An ultrasound corresponds to a frequency above 20 KHz. The human ear can perceive sound waves with frequencies between 20 Hz and 20 KHz Many phenomena generate ultrasound, the first of which is compressed air leaks and pressurised gas. The defects of bearing and lubrication, turbulence in the fluid or gas circuits, aeration and cavitation in pumps, electric partial discharge and corona effects and many other phenomena all generate ultrasound. In predictive maintenance the possibility to detect in an industrial environment the ultrasounds resulting from malfunctions can anticipate breakdowns and accidents and make energy savings. The Leakshooter v3+ is claimed to have significantly advanced this inspection technique. Considerable energy savings Compressed air is a costly form of energy and 20 to 40% of it is lost through leaks. Systematically checking for and eliminating leaks can therefore bring considerable energy savings. Users can film, view and photograph the precise spot where compressed air, steam, pressurised gases and vacuums are leaking using the Leakshooter v3+. The Leakshooter v3+ is said to be capable of finding all leaks, even the smallest, including those no bigger than the size of a syringe needle, at a distance of 20 metres. Leaks can be detected in all types of industrial environment thanks to the possibility of adjusting the gain on the device to filter out all undesirable noise. Used like a camera The Leakshooter v3+ is used like a camera. When it comes near a leak, a dynamic white target appears on the large colour screen. The target shrinks as it approaches the source of the leak. A bar graph at the bottom of the screen accompanies and facilitates the search. When the device is facing the leak, a cross appears around the centre of the target. It is then possible to photograph and save the precise location of the leak. The photos can be uploaded directly onto a PC via a USB cable, ready to be attached to inspection reports. It is still possible, whilst visually searching for a leak, to use the traditional method of leak detection, listening for the hissing sound of the leak using the professional headphones, which can be plugged directly into the device. Various accessories are available for the Leakshooter v3+ enabling it to be used for other applications as well as leak detection. For example; steam trap monitoring, bearing monitoring, electrical applications like partial discharge, corona effects, punctured isolators, electrical tracking detection. Also embedded within the Leakshooter v3+ is what is claimed to be the first automatic Steam Trap analyser, which can detect defective steam traps in seconds. www.leakshooter.co.uk Ultrasonic compressed air, gas and vacuum leak detector 52 HYDRAULICS & PNEUMATICS April/May 2019 www.hpmag.co.uk COMPRESSED AIR
