Thank you all. I will invite Parker Hannifin to a site visit for evaluation.

Normal Pressure is 2400 Psig Maximum Pressure is 3000 Psig

As per P&ID, Normal Temp is 115 F and Maximum Temp is 150 F. This is for the hydraulic oil For surroundings, I have to check. The actuator is on an open area but maybe subjected to nearby heat. I will check the tube surface temp by a temp gun Hoses are ok up to what Temp ?

Hi We have a hydraulic system controlling a stop valve for the steam turbine. As per OEM, it is required to do test for this valve on daily basis The supply oil to actuator is via a piping (hydraulic SAE flange) and the piping has a support. But I can see the piping sometimes vibrate during...

Hi all I have an air extraction line from gas turbine compressor with 250 Psi pressure & 700 F Temp. This air is to be treated with aftercooler & pressure reducing valve and then to the air tank. The Desired final parameters are 90 Psi & maximum of 200 F which will be stored in instrument air...

not sure how the control system calculates the flow. I will have a look at it

Hi all, We have the below parameters taken from our control system, and using below data I calculated the air speed and got around 66.4 m/s which is quit high Data: Air Temp: 605 F Air Pressure: 121.6 psig Calculated mass flow rate (calculated by control system): 25.6 lbm/s Valve opening...

electricpete Piece 2 is rotating and functions like slingers Point 3 being concetric or not, I will take a look at it again maybe tomorrow, since these are the only photos I have currently.

Thanks Tmoose Please see the how the hub is fitted in the shaft and condition of the teeth. teethes have wear on them (attached) I am not sure about the grid condition , but what I remember it was replaced and greased few months before the failure. For the TIR, when we measure with coupling...

One thing I forgot to mention, if we measure the runout with coupling hub installed on pump shaft (coupling de attached from motor), we get 12 mils which tells there was some coupling eccentricity If we measure directly on the shaft (with coupling hub removed) we get 7 mils

Hi BrianE22 No. Of course with coupling de attached. Also with coupling hub removed, so we can put the dial directly onto the shaft and see if there is any deflection We got a value of 7 mils on pump shaft as mentioned in the original post

For alignments readings, we couldn't take the as found reading since the shaft was already broken
