- So now we're gonna do a vibration test on this machine.
We've checked runout.
We're gonna use the machine defender app
to take some vibration data.
Now there's only a few things you need to know,
very basic things, to build this machine.
Number one, we need to know its horsepower.
Number two, we need to know its running speed.
And number three, we need to know the basic configuration.
This is a motor.
It has a coupling and it's driving
what we're gonna call an overhung fan.
So we're gonna set this machine up
and collect some data on it.
I'll go into new machine, wants to know the horsepower.
I'll call it one.
Wants to know the RPM.
We're gonna start it up
and we're gonna use a strobe light
just to lock in the running speed on the machine.
Let it get up to speed.
I will adjust my strobe light.
You could use a laser tachometer, do the same thing
as long as you got a piece of reflective tape.
And it looks like our running speed is 3,537 RPM.
So I'd probably write that down just to make a note of it
or just leave it running so I know.
So I just type in here three, five, three, seven.
It wants to know if it's on a solid base
or sitting on spring isolators or neoprene pads.
In this case, this is a steel table
sitting on hard rubber wheels onto the floor.
So we're gonna say this is a rigid machine.
I won't have to change that.
Lastly, we're gonna give it its configuration,
how it transmits power from one side to the other.
It doesn't use belts.
It doesn't use a gearbox.
So in this case, it defaults to a coupling.
We're gonna tell it there's a coupling here
and then we'll tell it that this is an overhung fan.
And we could go in and name the machine, whatever we like
in this case, we'll just stick with my machine.
I'll hit the check and we're ready to start collecting data.
So I'll start this machine up.
I'm gonna take my WLS sensor,
this wireless three axis sensor,
and I'm going to mount it on the outboard end of the motor.
You always measure from power transmission
in this direction.
So we'll go outboard motor, inboard, inboard fan, outboard.
So I'm gonna go to the outboard motor bearing.
I have to tell it where it's mounted.
I could mount it vertically.
I could mount it horizontally or I could mount it axially.
In this case, we're gonna mount right here on top.
So it's a vertical mount
and I need to tell the RT 300 where I'm putting the sensor.
And I would just hit the button to collect the data.
It only takes just a minute.
Now see these three red bars?
So I've got an X axis, a Y axis, and a Z axis.
All three of them red means all three are in alarm.
I'm gonna move over to the inboard bearing,
carefully mount my sensor,
go into the RT 300 tell it where I placed the sensor,
and tell it to collect the data.
And in this case, we're getting alarm bands
in all three directions.
That data's collected.
We'll move over to the inboard fan bearing,
mount our sensor.
Again, we tell the RT 300 where the sensor is,
tell it collect the data.
In this case, we've got a Y axis in alarm
but X and Z don't look too bad.
We'll move over to the outboard end.
Carefully mount our sensor.
And again, tell it our placement, collect the data.
As soon as the data is finished,
we can shut this machine down
and we're gonna get an instant diagnosis on site
as soon as the data's collected.
So let's shut the machine down.
While it's coasting down
I can touch on the diagnosis key
and it only takes just a moment.
Acura X is gonna look through
tell us what's wrong with this machine.
And right now it tells us
that we have a misalignment problem
which I knew we did because I misaligned it on purpose
so we would get an alarm of some sort.
So now red means we're in alarm.
It has three stars of confidence in its diagnosis.
I can touch on this down arrow here
and get a little better detailed analysis
of what's going on with the machine.
In this case, what would I do first?
The easiest thing is to align it.
If I can align it, I may fix any other kinds of problems
that may be going on or some,
but we know we have a misalignment problem.
So let's go in and fix that.
