VULKAN PRODUCTS
MONITORING SYSTEMS
These parts are manufactured by VULKAN COUPLINGS, Germany pioneers in marine drive technology.
Furtermore, VULKAN components are used in powerplant facilities or in industrial applications as well.
VULKAN production program includes following types, most available from the manufacturing site in Germany but some common ones are also available from our warehouse in Moschato:
TORVIB
TORVIB is able to indicate engine/motor overloading, resonances, and engine misfiring. This device is designed to monitor two and four stroke diesel motors, prime mover and shaft lines. Torsional vibration measurement is done by
measuring the time interval of the teeth of the flywheel. This time interval is converted to angular velocity, which is filtered and scaled to the correct value
of torsional vibration. Twist angle measurement is done with two pulses,
belts on both sides of the flexible coupling. The device measures the phase shift of these pulses and detects twist angle and twist vibration.
Benefits
Increase of safety –> gear, crankshaft, shaft line
• avoid overloading and unnecessary wear in the drive line
• ensuring highest reliability of non redundant components
• improvement availability of the complete drive line by avoiding
failures due to preventive maintenance as well as purposeful
planning of spare parts
for engine manufacturers, ship owners and shipbuilding industry
