During the machine starting phase, The IGVs were in the required position and bleed valves of the axial compressors were fully open.
The overload occurred at 6% of the required speed.
The logic not executing different sequence except when the temperatures achieve the alarm or trip conditions and...
Gents,
What are the causes of having overload on starter motor (driven a torque convertor voith turbo E 6 WAT) of GE MS 5001 turbine model when the machine is hot.
Please note that this happen only when the turbine wheel space is hot, however the overload on the starter motor doesn't occur when...
Hi Gents,
I would like firstly to introduce you to one system we have in our plant.
A sundyne compressor LMC-343 (in line single stage compressor driven by 5.5Kv motor) is used for regeneration.
It is equipped with a tandem dry gas seal (API Plan 52) which is splitted to process...
Hello everyone,
May you please advise on where ca I find the Thermal/Chemical/Physical charachteristics of the MS 5002/5001D Journal bearings.
Please note that it was not found on the vendor manual.
Thank you in advance.

Hello everyone,
Is there any guidelines concerning the effeciency calculations of a centrifugal compressor which is in service connected to real process system.
Thank you.
Gents,
Attached are a photo of a self lubricated journal bearing installed on the drive end of a centrifugal pump driven by 5.5kv
motor.
The bearing failed after being heated up then the temeprature transmitter sent a high temperature alarm(setting alarm: 85 C).
I would be grateful if you...
I appreciate your help Gents.
I would say that the switchover frequency is mostly based on the scheduled preventive maintenance (PMs) such as oil change
where the pump need to be out of service, However I believe that the frequency is certainly relative to the pumps
performance.Also it is...
Hello everyone,
One of our gas turbines generator need the adjustement of an orifice manual valve (istalled at the bottom of solenoid
valve in the torque convertor oil circuit), however, this valve is never adjusted on the other turbines.
The opening/closing of the solenoid valves is...
Micalbrch,
It's okay if something elese were damaged after identifying the cause.
The most common probleme we're facing on this type of pumps is the diaphragm being perforated after 6months aprox and
sometimes less, at the start up of the pump..etc
In the past we had another type of pumps...
Pumpsonly & Compositepro,
Thanks for your reply.
I would tell you that the failure occur aprox each 6 months for each pump.
I will check the adjustement of the valves within the hydraulich chamber.
What would you think Gents if I will check the torque value(should be 220N.m) for the cover...
Many thanks for your cooperation Terry.
I also contacted the manufacturer and he disagreed the oil substitution.
Our planners team had already established a purchase request for the suitable oil and hope everything will be okay with our pumps [thumbsup2] .
Thanks to everyone.
Also the pumphead drawing is attached here.

Hello Micalbrch,
Thank you for your cooperation.
PLease find the attached docs the technical data the drawing of the pump head + photos.
Many thanks.http://files.engineering.com/getfile.aspx?folder=1e3faed3-22d2-4501-8390-79032cc2e04f&file=BRUN_LUEBBE_PUMP_FAILURE_REPORT.pdf
