Guys, what's injectable packing ? Where it should be used ? What are its advantages and disadvantages ? Regards, Abualnassr

Thanks flexibox for your reply. The barrier fluid is oil SAE 30 with N2 gas. The problem is that we are having leakage of the barrier fluid from the top of the seal. By the way, what do you mean by topping up ? Regards,

Hi guys, We have an agitator with these parameters : T = 210 C P = 18 Barg The seal installed is EagleBurgmann HSL double seal. The plan used is Plan 53A, are the process parameters OK with the 53A ? Or it's recommended to upgrade the flushing system to 53B ? And, what is the max. temp. &...

Thanks pmover. As per the OEM manual speed = 5813 RPM. Mass flow rate = 21655 Kg/hr No inlet conditions mentioned in the manual. Regards,

dcasto, Do you mean by effective inlet area = impeller area - center bolt ? And effective discharge area = discharge spool area ? Regards,

Hi guys. I'm trying to calculate the polytropic head for a centrifugal compressor using this equation H = (1545/Mw)*Z*T1*(n/(n-1))*((P2/P1)^(((n-1)/n))-1) Where, Z = 0.996 n = 1.32 P1 = 16.87 PSIA P2 = 23.29 PSIA T1 = 740 R Mw = 68.5 My calculated H = 5579.62 ft But, according the OEM data...

Wimple, the compressor is 1 stage over-hung centrifugal compressor driven by a motor through a 1 stage speed increaser. Here are the design specs : Volume Flow Rate = 7060 Nm3/hr Mass Flow Rate = 21655.4 Kg/hr Suction Pressure = 0.15 Barg Suction Temperature = 138 ?C Inlet Volume = 10620 m3/hr...

Do you mean by effective inlet area = impeller area - center bolt ? And effective discharge area = discharge spool area ? Thanks for your help.

Well, the speed will not be changed(if you mean compressor speed). Do you think the increased pressure will increase the probability of thrust bearing failure ?!

dcasto, this compressor doesn't have thrust balancing system. Is there any way that I can make sure that the increase in pressure won't effect the internal components of the compressor ?! wimple, "lower speed" do you mean flow speed ?! Can you please elaborate more ? I really appreciate your...

thanks man

Gas is the same and dp is the same. But the only changes were inlet and discharge pressures. Well, i assume increasing the suction pressure might increase the thrust load. What do u think guys ?!

So, where should i put the tip of the dial indicator exactly ? Should i put on the bottom of the gear teeth or on the circular pitch line ?

Yes, after the melt of the seal we've done the alignment. And, now it's running smoothly. But you know what, I think the parallel misalignment was more than 24 mils when we checked it the first time with the laser alignment tool.

Hi guys. How can we measure the backlash without disassembling the gear for the gearbox ?
