Thanks georgeverghese, I'll check with the supplier.

Thanks georgeverghese, our buffer gas is fuel gas and it is dry. our DGS with two vents: a primary vent to flare and a secondary vent with another line ( not these lines from casing) to atmosphere, and with two injections: fuel gas and Nitrogen. and we have an indicator if the secondary seal is...

Thanks LittleInch, I don't know how much the temperature of the cover, but I want to know what's the meaning of cover leakage (head flange leakage?), if any one is familiar with this pipe or Centrifugal compressor that has these pipe, or any one has a document about this. I read that sometimes...

Thanks georgeverghese, I think these pipes are for leakage from the head flange (very hot suction pipe that means the Head flange's O-ring is damaged)? I want to confirm. Because the parameters of the DGS are very good. I want to confirm these pipes from the casing that meet with the primary...

Hi guys, A centrifugal compressor (Thermodyn), there are two pipes (see the picture), I want to know the role of this pipes and if the pipe of the suction side is very hot that means there is a problem...

Thanks electricpete, I catch the idea

Thanks GregLocock.

Thanks GregLocock for your answer, But I don't find the same result( 1.5gr at 72° and 1gr at 144°).

I want to know the formula to calculate the two masses in position 72° and 144° (they found 1.5gr and 1gr by the calculator) please see the file (page 11) to understand my meaninghttps://files.engineering.com/getfile.aspx?folder=62b87ad2-67aa-4305-af65-fd3965fe8cbf&file=bo0276.pdf

Thanks rotw

Hi rotw; for BCL 307 (after the Operating manual of the machine, 30 it is the nominal diameter =300mm,but the real diameter of impeller is 370mm) Thanks.

Hi guys; I want to know the relation between the real diameter and the nominal diameter of centrifugal compressor; for example for BCL307 (the real diameter of impeller is 370mm but the nominal diameter is 300mm). Thanks.

thanks flexoprinting, i will check what you propose.

Thanks electricpete, your reply is very helpfull, but the problem is the over heating of the driving side of the motor. I think the problem is the method of arrangement of spacers between bearings.

Skogsgurra I forget word "spacer", i mean inner spacer ring(L) and outer spacer ring (k). like the picture.

ScottyUK; your reply is very helpfull, but there isn't spring,there is inner rings (2KL10A C3). Thanks.

thanks flexoprinting for your help.

Hi Mr Flexoprinting; thanks for your help.

Hi Mr Edison123; I think it is clear, the deference is the arrangement of driving side bearings (7312AT DBD + 2KL10AC3). Thanks.

Hi; we have in our plant a vertical pump (EBARA) with 10 stages; to pump propane. the driver of this pump is a electric motor (Fuji electric). my question is how to mount driving side bearing (which figure is correct? fig1 or fig2? All information is attached. Thanks...
