The motor is not operated through a VFD May I ask, why...
Hi all,
I have a very generic question and I was hoping you guys could help me. Today we just changed the bearings out of a 1375 HP Squirrel cage motor and noticed that none of the journal bearings had any sort of insulation protection. I am more mechanically inclined than electrical but all...

Hi all,
This might be a dumb question but I am looking for some feedback from a more seasoned engineer regarding centrifugal pump bearing temp alarm limits.
The pumps in question are between bearings, single stage centrifugal pumps and there are about 2 years old. These pumps are mostly used...

This vessel does not have a platform on top, I don't know why it was designed like that; It also does not have a ladder up the side to the top. We have to bring a lift every time we inspect the valve or replace it. There is nothing else in top of the vessel...
