Need Advise Please-alignment tool recommendations-

Chris184 ·
No experience here in doing alignments, but now looking into getting a laser alignment system. Currently on the list is a Rotalign Ultra IS, Easy Laser E710, and a Fixturlaser NXA Pro. For you guys that do alignments what is your tool of choice. If you were to buy one today, what would you buy and why. Id like to try not to end up with something that will be regretted later. Something that will be important is the report generation feature, and I'm thinking that an emitter and receiver on...

Bolt bound, Alignment in horizontal position

CharlieRB ·
All; What methods or techniques do you use to resolve a horizontal bolt bound condition when performing a routine alignment task? Do you ever slot the foot bolt holes? Do you beg for more time from the powers-that-be to allow you to attempt to reposition the driven component? We have encountered what we believe to be situations where the OEM has not adequately aligned the component and modifications to the mounting base is required. Does slotting the holes of the feet have an adverse long or...

Causes of unbalance in rotating machinery

Maintenance Training ·
WHEN SPINNING EQUIPMENT IS OUT OF BALANCE When spinning equipment is out of balance. Vibration from out-of -balance rotating equipment can be frightening. The ground shakes, machines jump about, hold down bolts come loose and parts break. An unbalanced rotating body will produce forces on its bearings and transmit them throughout its structure and into the foundations.

Re: Vibration Tri Axial Sensor Mounting

With the HVA sheme, it is easier to understand direction/orientation of the plot. With RAT scheme, I always knew which transducer I was going to use Demodulation for (T). Other than that, it really depends on your preference; so I'm not sure there is a right or wrong answer. Always keep good records of exactly where you mounted and how you oriented the pad (assuming that's what you have) so that anyone can properly re-mount and orient it properly.

Well ask yourself this 1. whats the maximum span between measurement points you need? 2.do you have a vertical alignment requirement? 3. Do you need to align a multiple train e.g motor gearbox Pump/fan/etc? or is it simpler machines? Motor coupling Pump/fan etc? 4.Do you require the ability to generate conformance reports from the aligned equipment?

Prufteknik Rotalign Ultra iS are great machines (we use them here) But not everyone needs everything that it can do. There are many companies selling alignment systems... Some work great for very basic get it in the ballpark alignment. But you get what you pay for. Don't get hung up on cost alone. If the alignment...

We have a TKSA 11 as well. Comparing that to a rotoalign is like comparing a Yugo to a Ferrari. They both serve a purpose. The interface on the TKSA 11 is the easiest I have used.

Alignment of machines running at high temperatures requires initial offset so the machines aligns when the thermal expansion takes place. Talking about the amount of offset and the direction of offset manual is to be referred for protocol readings.

I have not aligned a NTM. If there are multiple flexible shaft couplings, then there are two procedures to consider: 1) laser measurement at each coupling (like most machines) 2) laser (or optical) transit of each bearing housing to common reference point I did align a 65-ft long machine train with 7-couplings. I measured each coupling with laser-optical system. I then determined the best moves (H and V) of each component by graphical scale drawing and calculated with spreadsheet. It was not...

questions: (1) Is it a centerhung or overhung fan? (2) Can you show us the impacting waveform? (3) Have you tried and failed with a single plane balance or are you planning on a single plane first or multi-plane balance first? (4)The 110 degree phase on the DE, what is the 110 referenced to, a refelection "tape" position on the shaft or reference to the NDE bearing? Thanks, Ralph

Re: Balancing of fan

"So my question is can we perform Dynamic Balancing ??" Yes, if rotor is accessible to add/remove balance weights. "if yes will we get satisfactory results?" Yes, if rotor is clean and no cracks or looseness and bearings are tight and in good condition. You should also inspect bearing pedestals/housing for loose bolts and foundation (steel, concrete, grout) for significant cracks. Walt
