In the past it has been my experience that piston non-slam type non-return (check)valves were the technology to use on the discharge piping to prevent flow reversal to a reiciprocating gas compressor.
More than one Tender on a gas compression project have submitted an axial flow type non-return...
In the API 661 / ISO 13706 section 9.3.4 Welded Tube to Tube Sheet Joints, it states that the purchaser shall specifiy whether the tube to tube sheet joints are to be strengthened or - seal welded.
A particular manufacturer has stated that anything over 2000 Psig is seal welded. Are there any...
Ok Rod Reversal Experts!
I would like to know if there is an existing technology for continuously monitoring the rod reversal of the pin in the cross head bushing that facilitates the lubrication of this section of a reciprocating compressor cylinder piston drive line mechanism.
We have...
Reviewing what everyone has been suggesting I would like to add to my earlier comments. The diagnostician should not just rely on an isolated symptom such as an increased radial vibration to diagnose a faulty bearing. One should examine the spectrum trend if this is available comparing it with...
Most of my experience has been with diagnosing sleeve, journal or babbit bearings. I have used eddy current displacement probes comparing them to casing measurements.
The symptoms of the faulty bearing will change over time so you will notice differences in the vibration spectrum, bode and...
mtigos,
I have read all of the discussions and I have not seen mentioned a very important step. This is a flu gas fan, a very large one. It was mentioned that it is always going out of balance.
If you have already thought of this please forgive me, but it strikes me that the first thing...
When replacing the Buffer air seals on a solar gas compressor it was noted that there was some contamination on the seal housing walls of the compressor on the coupling side seal.It was light brown slimy residue in appearance and texture.
This compressor was contaminated with water soon after...
Electricpete thanks for the information on balancing an overhung rotor fan when pillow block bearings are involved.
Expanding the conditions for overhung rotors. Is there any difference from the coupled two bearing mounting method for balancing an overhung rotor directly mounted onto the motor...
What is the best practice for the field balancing of overhung rotors,ie, pillow block mounted, direct mounted on the motor shaft and direct mounted vertical orientation?
I have an analyser balancing program that uses 4 mearsurement points. It is capable of balancing multiplane. It does give a...
Everyone,
I forgot to include that the gears are double helical.

I am creating a fault frequency set for analysis in a condition monitoring program on a compressor driven through an epicyclic gear increaser. My request is for the formulae to calculate the tooth mesh frequencies in this type of gear assembly and any other useful tips regarding this type of...
