I want to know if this louvers infuence or disturbe the air suction of the axial compressor of turbine.
they were changed by others not identical in dimensions.(extrnal sizing the same but internal elements are different)
these louvers are situated in air chamber of turbine
we have a problem with starting a gas turbine all is ready but at 4200tr/mn we have a shut down
the only think that we have changed is the dust louver but with not the right one in dimensions so I ask if this change influence on the machine and exactely at axial compressor of the turbine? the...
Hi,
After dismantling the butterfly valve (control Valve Model:Valdisk BX flowserve)
we found the spiral wound with SS outer inner ring damage ,deterioration of the gasket it was the main cause of the problem
the choice of the gasket was not right 12" Instead of 14", so the inner ring was not...
Yes it is a internal pipe filter (conic with mesh )
the filter is not yet open
and also the control valve not yet inspected or dismantel
only the control valve internal accessories witch are on contact direct with inlet compressor
control valve in the inlet is for regulating the fuction...
WE FOUND SERIOUS DAMAGE ON THE FIRST STAGE IMPELLER ( photos attached)
with a metallic debris in suction line or piping of the compressor.
the question from where they come this fragments of metal?
before entring the gas compressor we have filter and then flow control valve (Valdisk BX...
EXCUSE ME BP IS LOW PRESSURE SUCTION L.P (BP IS IN FRENCH BASE PRESSION)
this compressor will compress the propane that is boiled off from a large storage tank of refrigerared liquid propane gas.
the problem when we start the COMPRESSOR we have a noissy sound at the medium stage piping with a...
WE HEAR A NOISE IN THE M.P STAGE PIPING SPECIALLY WITH VIBRATION AT THE COMMON SHAFT OF B.P AND M.P WITH SENSOR ON LIGNE ,but Nothing with off ligne vibration what is the phenomena ?
Sorry,I will explain for more informations please try to understand me BECAUSE OF MY ENGLISH
this motor was in overhaull inspection (mechaniccally and electrically) all tincks were inspected ,but the only thinh the fan was broken and replaced by another oversized because we haven't the...
what is the impact or influance of changing the cooling fan on non -drive end shaft of an vertical electric motor of 225 kw power with another which is not the same and it make noise?
Hi
What I understand ,I think the problem reside in many points that you have to verify.
- quality & ORIGINALTY of the bearing.
- seals shaft contact .
- grease quantity and type and if it is not mixed.
- type of cooling fan of the motor
- alignement
Hi
excuse me
from the instruction manual of the pumpwe have
The set point for the maximum deviation is of 0.03mm per meter length of the shaft.
And I have 0.08mm for one meter and half the length of shaftpump.
after disassembling the pump ,we noted that also bushings are out off tolerance and...
Hi friend's
it's exactly one half running speed.
added information
pumped liquid: propane
discharge head :114m
quantity:292.8m3/h
speed:2950rpm
pump type:16WUC-3+ind.flowserve.
If I REDUCE THE SHAFT DEFLECTION , BECAUSE THE RUN OUT IS ABOUT 8/100 OF ONE METER AND HALF AND THE RECOMMANDED IS...
Hi Johnny
I believe it is a very complex subject above my head and you have suggested that you could provides references for particular bushing design .
yes,Iam interesting can you explain me more
Thank you for sharing your knowledge .
First, I tell you that the motor alone without pump doesn’t vibrate, but coupled will vibrate,
In none drive side or end of the motor only, at 1/2 rotation frequency (25Hz) we have a peak of 9mm/s, on the spectrum. The other side of the motor (DRIVE END) nothing and also on the pump bearing...
I need documentation or help for a problem of vibration.first a will explain to you that I have this problem in a vertical pump driven by a motor at speed of 3000rpm and power 75KW ,motor with 2 bearings upper and lower and pump bearing with 2 shaft assembled together.
the problem happens at...
