- So now we're gonna simulate doing
a vertical shaft alignment with the RT-300.
Vertical shaft alignment isn't as common in industry,
but in some industries you do see a lot
of vertically oriented machines.
Most of the time this is it with a C-Face Flange.
We don't have one of these set up here
so we're just gonna simulate it
with our standard demonstrator
and I think you'll get the process.
Just preface it by this:
A lot of people think that vertical machines don't need
an alignment check because that C-Face Flange has
a rabbet joint that's machined around it
so that the C-Face Flange bolts into the,
to the top of the pump assembly.
But I have seen them out of alignment due to machine errors
or dirt build-up or whatever.
So we're gonna go through that, this process
and I think you'll see how it works.
I'm gonna go into the vertical shaft alignment application.
And so now we've got green lights here
so we know our sensors are paired and seeing each other.
Going into our measurements here.
And the first thing we've gotta put in
is the distance from the stationary to the movable sensors.
In this case we are at 164 millimeters.
I now want to know the distance from the M-sensor
to the center of the coupling.
And I can guesstimate that to be about 90 millimeters.
Now this third dimension is a little different
than we have a set up here.
What it's asking for now, if you look here on the screen,
it asks you for the diameter of the C-Face Flange.
So if this machine were a real vertical,
we'd have that C-Face mounting in a bolt circle.
And let's just say for our sake of conversation
this is a 300 millimeter bolt circle.
The last thing I'd ask is how many bolts are in that circle?
Typically it's four and we'll put it in as four
and see what happens.
So we're just gonna say it has four bolts in the circle.
We'll put in the RPM as let's just say it runs at 1800.
So we'll choose the, of the, tolerance for that.
And now we're ready to take our measurements.
So if you'll notice here
on the screen, we've got guidance here with a number one.
It is important that you number your bolts
in the bolt circle one, two, three, and four.
Doesn't matter if they're clockwise or counter-clockwise,
that's fine as long as you know which way it is.
But we're gonna make an assumption that our sensors,
these TDS are pointing toward bolt number one
and we're gonna take the first measurement here.
Once that measurement's completed
we're gonna rotate 90 degrees.
In our case, our simulation here is
with a four-bolt bolt circle.
If this were an eight-bolt circle,
we'd go from bolt number one to bolt number three.
We'd skipped two.
So we wanna rotate 90 degrees.
We'll take our second measurement here.
And lastly, in our case we're gonna rotate 90 more degrees
so that we're pointing toward bolt number three.
Again if this were an eight-bolt circle,
we'd be pointing to bolt number five
and we'll take our third measurement here.
And so what the RT-300 is gonna tell us is this:
We do have a misalignment problem.
I can tell the orientation by looking here.
I have a guidance on this image.
It shows me that bolt number one is facing me.
I'd be in front of it here.
On this image bolt number one is to the right.
So I'd be facing it from here.
And here's how much shim we need
to correct this alignment problem.
We needed a 0.56 millimeters under bolt number one,
nothing under bolt number two, that's the high spot.
We need a half a millimeter under bolt number three
and we need a, just over one millimeter
under bolt number four.
So if we add those shims in,
we would realign our motor and we'd be in great shape.
