Leak
Detection |
Compressed air leaks
are the most expensive utility waste in manufacturing.
Turbulence from leaks creates white noise with
a strong ultrasonic component. Scan an area with
the Ultrawave and hear the turbulent rushing sound
through the headphones. Ultrawave pinpoints all
pressurized gas and vacuum leaks regardless of
ambient background noise. Finding leaks can save
hundreds of thousands of dollars. |
Bearing
Condition Monitoring |
Roller bearings produce
ultrasonic friction as the internal rolling elements
turn against the raceway. Likewise, the friction
absorbing properties of grease means a well-lubricated
bearing produces less friction than a bearing
that lacks lubrication. True digital RMS readings
from the SDT 170 provide accurate and reliable
advanced warning of impending failures to rotating
equipment. |
Ultrasound
Condition
Based Lubrication |
AVM™ - Acoustic Vibration
Monitoring trends high frequency bearing energy
to determine proper lubrication intervals and
predict when the bearing is entering its FIRST
stages of wear. Over lubricating bearings can
damage seals, build pressure on the bearing, and
cause premature failures. Over greasing an electric
motor can push lubricant into the windings causing
shorts and more severe damage. Under lubricating
bearings negatively affects the lifespan of rotating
machinery also. So how can you get it just right??
The SDT 170's advanced digital detection techniques
opens up communications between bearing and lubricator.
Let the bearing tell you how much grease is enough. |
Steam
Trap Inspection |
Rising energy costs make
steam an expensive utility… too expensive to waste.
A typical failure rate is 30-40% of a facility's
steam trap population. Failed traps also contribute
to contaminated, poor quality steam and dangerous
water hammer. Ultrasonic testing gives the inspector
an "inside view" of the trap. The SDT 170 translates
high frequency ultrasonic noise to audible frequencies
localized to the source of contact. The inspector
will not be disturbed from ambient parasite noise
downstream. Temperature measurements upstream
and downstream of the trap can often provide alerts
to failed traps. The SDT 170 M and 170 MD Steam
Trap Inspector's Kit includes a standard non-contact
temperature measurement interface to further enhance
trap inspections. |
Valves
and Hydraulics |
Internal blockage or
leaks in valves can be discovered precisely while
the system is on-line. Troubleshooting hydraulic
circuits to find internal leakage is fast and
easy with the Ultrawave. With the Ultrawave in
"contact mode" take sample readings along the
circuit. Technicians can clearly define the direction
of flow, and more importantly, the source of trouble
even in high noise areas. Internal leakage across
seals on hydraulic rams produce microscopic bubbles
of oil which in turn "pop" as they pass from pressure
side to non-pressure side. These small explosions
produce ultrasound energy which is easily detected
in the Ultrawave's headset. Tune the frequency
of the detector to eliminate competing ultrasounds. |
Pump
Cavitation |
Cavitation is usually
the result of a pump being asked to do something
beyond its specification. Small cavities of air
develop behind the vanes. These pockets have a
destructive effect on the pump's internal components,
including pitting and scarring the surface of
the vanes. With the Ultrawave in contact mode,
isolate the pump vanes and listen for small air
pocket explosions. Comparing similar pumps will
help the uninitiated, but with some experience
an operator will quickly be able to detect pump
Cavitation. |
Boiler,
Heat Exchanger,
and Condenser Leaks |
Use the Ultrawave to
scan for external pressure or vacuum leaks in
boilers, heat exchangers, and condensers. Listen
for the same rushing sound that is associated
with compressed gas and vacuum leaks. All pipe
connections, flanges, seals, and access doors
should be inspected as part of regular PM's. Tube
leaks in condensers and heat exchangers can be
inspected using either the pressure method, the
vacuum method, or the bisonic transmitter method.
Choose the method that suits your application
and see your inspection time decrease dramatically. |
Reciprocating
Compressors |
Reciprocating compressor
valves open and close to allow internal combustion
motors to "breath". When these valves become dirty,
or carbonized, their efficiency is reduced. A
valve that is seating properly should be quiet
while defective valves are characterized by the
familiar rushing or turbulent sound of a leak.
Signals from valves can be analyzed with SDT's
Ultranalysis™ software. Real-time waveform analysis
will reveal heavy jagged peaks representative
of valve leaks. Trend these changes to PC with
the SDT 170 MD and Datamanager™ software. |
Electrical
Inspections |
Corona
discharge, arcing, tracking, damaged line bushings,
and other potentially dangerous and wasteful
conditions in high voltage systems produce ultrasound
as a warning of future failure. By itself, or
as a compliment to Infrared Imaging, Ultrasonic
Detection has become the technology of choice
for electrical inspections of:
• Transmission & Distribution Lines
• Substation Inspections
• Switch Gearo Transformers
• Partial Discharge
• Arcing, Tracking, and Corona
• Radio/TV Interference
Electrical faults emit ultrasound at the site
of the problem. Scan an area in the same way
one would for leaks. Characteristic frying,
popping, buzzing, and humming sounds can be
associated with different faults. Build a library
of faults by recording sound waves and sharing
them on your company intranet. |
Tightness
Integrity - Wind Noise & Water Leaks |
Quality
control applications were developed for the transportation
sector to improve the tightness of vehicles. The
method consists of flooding the interior of a
volume with microscopic ultrasound waves. Due
to their properties these waves can penetrate
small holes. Using the SDT 170 detector on the
outside of the volume inspectors can quickly pinpoint
the source of defects that could become potential
sites of water leaks or wind noise. Current sector
uses: Marine Industry –
Hatch Covers of Cargo Ships
Automobile – Wind and Water
Leaks on Cars
Aeronautics – Integrity of
Aircraft and Helicopters
Transportation – Trucks, Buses,
Trains
Buildings – Integrity of Building
