I'm trying to find a way to calculate the max load a fork lift can handle if you are using fork extensions, for example I have a lift rated at 5400 lbs at 24 in load center. How would I figure max capacity at 36 in load center. Reason I am asking is I have a gear box that I have to remove and...
Can anyone point me to or give me insight on the OSHA standard for expanded metal mesh size limits for coupling guards. I want to modify some guards on our inert gas system blowers. They are currently made of a solid heavy guage SS sheet metal and house a Rexnord Omega rubber tire coupling...
yesterday I was walking by one of our flash tanks, 450# cond to 90#steam, and heard a hissing sound. I couldn't really tell if it was a leak at the sight glass, which is common at our facility, or coming from somewhere else. I scanned the sight glass with our e-4 camera and saw nothing. Instinct...
I am looking for some info on a US motor. It is a model 7972B, 40 Hp, 1775 rpm, 324T frame, 460 V, 47.5 amp, type TCE, corro-duty, premium efficiency motor. I am trying to get # of rotor bars and stator slots. I tried their website but to no avail. Also called and have not heard back as of yet...
What do you call the wobbling effect on an agitator shaft caused by a vortex in a mixing vessel?

This may or may not be an issue. I happened upon a strange phenomenon with the supply cables for our variable frequency spin pump motors.While collecting vibe data on these units I noticed a strange "noise" in my headphones. It was almost like an arching sound when my metal encased accelerometer...
Hi all,
I'm looking for info concerning acceptable runout and concentricity tolerances for the bobinn chucks on fiber winders. We have found that the bearing housings of our winders are "wallowing" out, I assume due to vibration issues. We plan to have an outside contractor perform...
I am currently doing an ultrasonic leak detection survey of the building that I work in. Air and N2 leaks are the prime targets in this survey. Has any one done a "dollars lost"/year type survey like this before. What should I take into account to estimate losses ie pressure, line...
Dear all,
Please correct me if I am wrong. The best time to use IR for roof leak detection is at night ( or possibly a dull overcast day). I understand that IR won't pinpoint leak, but will show where water has permeated into the insulation. I have been asked by my upper management to shoot...
If any one has any information on Arpuma 2 stage liquid ring vacuum pump please let me know. I'm especially looking for torque values on the tie rods and any clearance setting info available. I've tried their website but it's in German and difficult to navigate.
Thanking all in advance for any...
I'm looking for any info (links to articles, communications with other program administrators, cost saving calculation methods, etc.) to help with justifying the benefits of having a proactive/predictive based maintenance program. As we are all aware, the benifits can be astronomical in dollar...
Can anyone give me directions to or suggest a sealant that will bond, cure and seal in a very wet enviroment. We have a cooling tower cell, no way to isolate, that has a leak that we need to seal due to the amount of make-up water we are using. This will only be a temporary fix until we can get...
I work for a synthetic fiber manufacturer and a lot of our piping as well as insulation jacketing is 304 and 316 ss ( @ 80%). Our process is dependent on strictly controlled temperatures, deviations of 2-3 deg. C can throw our product off-spec. We have problems with line pluggage and heat loss...
John,
Thanks for the damping papers. Just browsing through them, I can see that they are going to be a great help for me. Oh by the way, I see you are in NY. I am also a native New Yorker, born in Plattsburg and graduated from Camden High School. Coming from a military family I came to settle in...
Where would I begin to search for motor bearing #'s (OB) and sleeve bearing type/composition (IB) for Trane centravac chillers. We have 6 units, 3 are 900 ton and 3 are 500 ton ( I think). We are taking over the predictive maintenance end of our service agreement and I need to know this info for...
I work for a synthetic fibers plant and would like to learn more about vibration dampening. As with any "fiber winding" process there is always a risk of operating through multiple natural frequencies of the winding equipments components (it's just the nature of the beast). Any links...

Is it possible to calculate the mean time to failure for a ss tank top with a top mounted agitator. What we have is a tank with top mounted agitator that stirs a viscous solution (not sure of viscosity) at a speed of @ 60 rpm. This solution will "gel" when exposed to the atmosphere. I...
Does anyone have references to sites that I can download info concerning rigging/slings. Needed for safety presentation. Roy Gariepy

First of all, I know that FEA is a much more indepth process of analyzing a structure or system through animation based on vibratory info, and that some of the FEA guru's within this site may consider it neanderthalic, but I am a firm believer in "it doesn't hurt to ask". I am...
