Compressor/Motor alignment

[NH3ISFORME]

Does anyone know of any information online or elsewhere
I could learn-up on motor alignment with dial indicators? Or maybe someone out there is well educated with this.

This is the kit I use

Small very accurate and a real nice price point compared to alot of the units out there.

Many forms of dial seem to be disappearing Knowing how to rim and face and cross dial use to be standard. but the easy of kits like the laser kit. It seems pretty hard to teach the old school forms of alignment.

Here is a good link on alignment though

I like this book, it has all the basics.http://www.carlylecompressor.com/Fil...ent_lowres.pdf

Hi, NH3LVR

I like this book, it has all the basics.http://www.carlylecompressor.com/Fil...ent_lowres.pdf

this one seems very nice ... easy to learn ... only few steps and not too much to calculate ... I have a similar one from Sabroe ... need to find it and post here...


Dear NH3ISFORME, please do not post the same question around ... one is quite enough ... double means the second one is too much

Best regards, Josip

The only thing to maybe add which is important is motor and in some cases compressor " soft foot " .

This is where one or several of the motor feet are not level or not with even contact on the base .

This can be a major problem if trying to get close tolerance .

With motor sitting on base not bolted down a feeler gauge can be used to find low or uneven contact . This should be corrected with shim .
When motor is bolted down tight , undo one bolt only at a time to see if shim is loose or can be moved .
If you can it needs to be corrected with more shim , usually 0.001" to 0.002 " thicker .
Check each foot in same way until happy then commence alignment .
( A dial indicator on foot to be loostened is another method to see if motor foot has any deflection ).

A " soft foot " can occur from poor or distorted base . Also mounted on floor or plinth that is not level to name a few .
This causes stress on all components and alignment will not stay true for long .
Can be contributed to shaft seal leakage .

Hi, all

as promised in above post ... here is the best way (of course for me) for easy and fast way to make a good alignment ...

It is from Sabroe manual, but I'm using it to teach young lads for many years.

Best regards, Josip

Hi RANGER 1.
I totally agree with the 'soft foot ' problem. You can spend huge hours sorting out and getting it right particually with dual DTI's . Very stressfull and time consuming.
Currently use a Laser alignment Tech who nows his stuff and can reduce job time to fraction with high tech analizer thingo.., expensive, but cheaper in the long term. He will do a cold set-up and re-check after hot run and balance settings for optimal settings paticually for composite sets with horzontal separators that move during operation from cold. No more shaft seal issues, and I have still got some hair on a balding head.
