The
GCF
Model 126 Portable Oil & Fluid Quality Analyzer
can indicate the quality and condition of your engine's oils and
fluids in less than 30 seconds. The system is fully portable,
mounted in its own case and can be taken anywhere. The results
produced by the kit have been confirmed using independent
laboratory analysis. ONLY $1,396.50
at www.reliabilitydirect.com!
circOil®
One Drop Lubricant Analysis - Our patented circOil®
test kit has been scientifically developed as an oil analysis kit
for plant maintenance people and individuals.

the Expert: Wolf Campbell, P.E. |
| Question:
"Are Screw-on Balancing Weights safe or appropriate for field
balancing?"
Answer:
While at times I have had weights fabricated in the
shop and welded on, there are many instances where screw on weights
are extremely useful and convenient when installed (and
manufactured) properly. For example, the C-Clamp weights
I use have a serrated surface opposite the set screw that acts like
a second set screw (it digs into the fan blade). I will apply
Depend 330 adhesive to the threads for added protection and on
large radius machines that require heavy weights, it is prudent to
weld the weights in place. If you have a quality shop on site, you
can certainly make your own weights. Consider the time, material,
labor, and quality of the end product to see if it is as cost
effective as buying professionally made weights. P.S. Always stay
out of the machines "Line of Fire".

Balancing
Weights! Reliability
Direct provides an assortment of balancing weights; conveniently
packaged in Kits or as individual weights. Select from a variety of
styles including Squirrel Cage, Air Foil and C-Clamp's.
STILT
LEG® Shims
& STRAIGHT LEG®
Shims are manufactured from the highest quality,
corrosive -resistant stainless steel. The shims are dimensionally
uniform and electro-etched for permanent easy to read
identification. The shims come in a variety of standard assortments
and each kit is offered in a sturdy metal carrying case with a
removal tool. Shims are also available in any custom assortment to
fit your needs.
The
PLT-5000 Pocket Laser Tachometer comes as a complete
kit with all the accessories needed for accurate contact or laser
sharp non-contact measuring. Three different sizes of
wheels and cones and a simple to attach adaptor, will meet
most of your contact needs, and the Laser Beam will make you
non-contact measuring easier to achieve at a greater distance.

| Application
Note: Portable Oil Analysis |
|
Oil Analysis will detect microscopic
wear particles long before your equipment starts to vibrate, heat
up, or show signs of wear. Oil analysis will also evaluate the
oil's ability to seal, cool, clean and lubricate as well as detect
contamination by water, coolant, or other fluids, or other
particulate contamination. The use of portable instrumentation to
screen oil samples for sophisticated lab testing and spot trends,
which indicate emerging problems, is gaining in usage.
A Portable Analyzer can be used to
test lube or engine oils, transmission fluids, gear oils,
hydraulic fluids, and any other petroleum based fluids. it should
come with a starter kit of supplies and a reusable
sampling device to let you begin testing immediately.
The most common method to check fluids
is Dielectric testing. The dielectric constant is a measure of
oil's ability to conduct electric current. Uncontaminated new oil
products conduct very little electricity. However, as oil is used,
contaminants such as wear metals, acids, moisture, and fuel soot
carbons enter the oil. All of these contaminants elevate oil's
ability to conduct electricity. The instrument tests the
dielectric constant of the used oil as compared to the dielectric
constant of new oil of the same type. The GCF
Model 126 detects these increases and converts them into a
numerical reading. By monitoring the increases, we can determine
the level of contamination within the oil. The test is simple,
fast and the controls are easy to use.
By monitoring the levels of contamination, the actual time
when filter and fluid changes are required is determined. We
include simple-to-use charts, which the readings from the
analyzer are transferred to. Thresholds have been established
for filter change intervals, complete fluid analysis, and if
necessary, a complete fluid and filter change. The charts can be
kept on hand or the information transferred to a computer for
long-term trend analysis. Charts are available for most every
internal combustion engine and hydraulic system.
When properly utilized the maintenance person knows the
condition of the lube oil and fluids within the equipment and
when to opt for a complete laboratory fluid analysis.

| Case
History: Frame Vibration on Reciprocating
Compressor |
| A petrochemical plant
wanted to upgrade their mechanical vibration switch that they were
using for local shutdown on several reciprocating compressors. When
properly applied, monitoring Frame Vibration can
help prevent catastrophic failures. In the event of a failure, the
damage to a reciprocating machine can be reduced. Our solution was
to provide a single channel, dual limit solid state vibration
monitor. The CMCP1000 is
a single channel Vibration Monitor with an integral accelerometer
packaged in an explosion-proof housing suitable for NEC Division I
hazardous areas. Designed to comply with API670 standards, the
CMCP1000 far exceeds the capabilities of competitive vibration
switches. The unit also provides a buffered transducer output for
detailed diagnostics. The CMCP1000 a local display in terms of velocity
with a full scale range of 0 to 1.0 in/sec. Options include other
full scale range selections, filters and a local external reset
button. |
