VDMA 36 VDMA MINING SUPPLEMENT • 2018 attaches to the widely used Dräger FPS 7000 RP full-face mask easily. In addition, it includes a voice amplifier that is voice activated, so it is hands free, allowing for more mobility. Every unit has an interface that connects to a radio with a cable or via Bluetooth. Connections to the most frequently used radios underground are available. All the rescuer needs to do is simply press the push-to-talk button to activate the voice communication through the radio. If a mine is already equipped with communication infrastructure and radio, the Dräger FPS-COM 5000 can be easily integrated and is ready to use for applications underground as well as above ground. In keeping with the Smart Mining vision, the FPS-COM 5000 fits as an integrated part of the communications' sys- tem within the team and fresh air base, which is crucial in order to concentrate on the job at hand. Some mines also require cable-supported communications for its rescue teams to be able to work independently from the infrastructure of the mine. Therefore, a version for such an application is in prepa- ration. It would work independently from any other possible station- ary-installed system. This means that operating the Dräger FPS-COM 5000 would be the same as any cable-supported communication sys- tem. It would include the voice amplifier, but instead of using a radio cable, it would connect the team to the fresh air base independently. First introduced at the 2016 International Mines Rescue Com- petition in Canada, the Dräger FPS-COM 5000 was tested by a total of 27 teams. The communication system was tested and tried under realistic underground rescue scenarios and received impressive, positive feedback. It was also commended as a viable and positive solution with real benefit for the future of mines rescue. Variable Speed Diaphragm Pump The hydraulic membrane Quadruplex (HMQ) diaphragm pump is a quadruple-acting piston membrane pump. When they move in either of two directions, the delivery pistons activate, by means of two cylinders, the four product diaphragms in the radial direction with respect to the pistons. The power transmission is ensured by the hydraulic fluid. The (equal) linear deflection of the diaphragms is ensured by a mechanical diaphragm position control. The product valves are opened accordingly to the suction stroke or the discharge stroke of the diaphragm. At each product side, there is one suction valve and one discharge valve. For a low pulsation operation, ABEL provides a special pulsation dampener, which is also equipped with an automatic regulation system. The HMQ is powered electrically and, when a frequency converter is used, it is well suited for pumping at very different flow rates (gen- erally at 10%-100% of the specified flow rate). Intermediate gear- boxes or belt/pulley systems, in case of a lower power transmission, are used as a gear reduction between drive motor and HMQ gear.
