Tightness testing Predictive maintenance
The most efficient way to ensure tightness is to test for it using
ultrasonics. The testing can be either fully integrated into the
production process, or carried out later as a control. To ensure
the most accurate results, SDT provides equipment that can
detect naturally occurring ultrasounds and those produced by
a transmitter.SDT's experience covers the full spectrum, from large volumessuch as buildings, cold and "white" rooms down to cockpits,
vehicles and electrical cabinets. This is done using a transmitter
and a
detector.Ultrasonics are also invaluable in establishing the tightness ofreservoirs, covers and underground fuel tanks. Ultrasounds are
detected by lowering the pressure within the tank. SDT has developed ultrasound solutions for detecting
wear and tear in mechanical appliances such as:• Fast and slow ball-bearings, commutator brushes, gearpinions, clack-valves, injectors, springs and bearings.Further applications can test
• Unusual and parasite vibrations in machines; • The running of pumps, motors, turbines and gear-boxes.Precise measurements can also be taken:
• Temperature control, with or without contact; • Rotation or linear speeds, with or without contact; • Sound levels;
• Air mass flow (flow measurements of compressed air leaks).
Leak detection
In every sector, leaks mean loss. In water and fluid pipes, it can
mean loss of product. In compressed air systems, steam pipes and
heating installations, it means increased energy costs to generate
lost pressure and heat. SDT's solutions effectively pinpoint problems in:
• Oxygen, compressed air, steam and gaseous fluid circuits, inparticular valves, electro-magnetic sluice gates, hydraulic
and clack valves, jacks and turbines; • Heat exchangers, gearboxes, pump cavitations, condensers,boilers, Manifold air distributors, etc.; • Inflatables (rafts, evacuation slides, etc.); • Pressure drops and vacuums; • Coronas and arcs in electrical equipment (transformers, circuit-breakers, relays, etc.).
