Permanently sealed –

Permanently sealed – independent of the pair of materials In practice leaks occur again and again in the region of the seal with screw-fit hydraulic components. The reason for this is that in the installation of hose pipes connections frequently the tightening torque is exceeded. With the new Ecovos fittings from Voswinkel GmbH with block stop safety the end of installation is displayed. The difference to the usual sealing cone fittings here is in the predetermined space between the two front faces of the components to be screwed together. This space prevents over tightening of the tightening torque and ensures that the prestressing necessary is achieved in the screw-threaded pair. This prevents the fitting loosening independently when placed under a load. Even when loosened and re-connected repeatedly the full sealing function is achieved. What is nor the block stop safety holds independent of the pair of materials. The user does not need to adjust the tightening torques, for example when pairing up the hose fitting with cast-iron or wrought-iron screw connectors. Ecovos hose fitting is supplied in nominal diameters of DN06 - DN16 and is expected to be available from the second quarter of 2016. www.voswinkel.net Suction and lowpressure hose for extreme weather conditions For use in extreme weather conditions or in particularly tight uinstallation spaces e.g. construction vehicles the company Dietzel Hydraulik is presenting the suction and low-pressure hose 17A with temperature resistance from -40 to 100 °C. On the basis of its structure, of two high tension resistant braided textile insert linings and two parallel steel wire spirals, in comparison to the In the event of ...

The hose is available in the nominal diameters DN19 to DN152. In addition Dietzel supplies tested systems, i.e. the integration in all available nominal diameters were tested using vacuum, density and bursting pressure tests. Integration is possible with ferrules and hose clamps. “As manufacturer of percision machining machines, we place high demands on quality, reliability and safety.

MACHINE ELEMENTS Ethernet cabling solutions for “Smart Factory” Author: Ralf Moebus, Head of Product Management, Automation and Networks at U.I. Lapp GmbH Ralf Moebus After four years of discussions on the “fourth industrial revolution” and “Smart factory”, there is an ever-increasing desire to see something tangible. In other words, there are demands for concepts which can be materialized. MDA Technologies 3/2016
