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...
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...

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
Hi dvd
The coupling size is 1060T and shaft size is 1 1/8"
Just to clear one thing, What I mean by runout is shaft deflection where the dial base is fixed on pump housing or support and the dial pin is on the shaft. rotate by hand and see how much high spot is there.
I know it is not common...

Hi All
Recently we had a failure on a motor shaft (attached)
the motor is vertical and connected to lube oil centrifugal pump via grid coupling
After the failure, we confirmed both motor shaft and pump shaft are rotating freely
The only finding was pump shaft runout to be 7 mils. We...
Hello All
We have a system described in the attached photo. We want to charge the system and increase its pressure into 35 psig so we can make a leak test on system flanges.
We have 3/4 plug connection where we want to connect it into a portable air compressor.
How can we calculate the...
