Thanks for shedding some light on this for me...I'll check out those articles you mentioned, electricpete. Thanks again!

Please excuse me if I present this information in an unfamiliar manner, as I am very unfamiliar with Electric Motors and Magnetism. We have been experiencing times of high vibrations being read by proximity probes installed within a 3600 RPM, 3500 HP, Electic Motor. However, taking readings at...

Will Mobil 1 Synthetic based barrier fluids attack mechanical seals with Carbon vs. Tungsten Carbide faces?

What function will installing the capacitor and resistor in series do?

Has anyone experienced interference between hand held radios and vibration transmitters installed on rotating equipment? At our facility, the vibration transmitters installed on several compressors inadvertently go into a state of alarm when exposed to a near radio signal. This causes...

Hey guys...For Crude oil application, we have a pilot operated pressure relief valve, set pressure of 235 psi, which has recently been "leaking by" with only 14-15 psi on the line. What are possible causes of this? There is a filter screen installed in the pilot sense line which may be plugged...

Could you elaborate a little more on the differential pressure conditions? Wouldn't the dome be seeing the same pressure as the inlet? and if so, the larger area would provide more force to keep the main valve closed.

No, it is not submerged in any fluid. It is located at the top of a crude oil storage tank, which is potentially a corrosive atmosphere.

No, it is not submerged in water. However, a corrosive atmosphere is present, as it is a crude oil storage tank.

gr2vessels....what do you mean by "good ole davit"?

Well, its a completely steel hatch lid measuring 34 1/2" x 34 1/2". I'm not sure about it's thickness, maybe 1/4".

Currently the Crude Oil Storage Tanks at our facility have roof hatches that allow for inspection of the internal floating roofs. The hatch lid is made of Carbon Steel (not sure which type), however, it is very heavy for operators to lift regularly when inspecting the internal floating roof...

Does anyone have experience with biodegradable hydraulic fluids and how they compare to typical petroleum based fluid when used in heavy machinery? How does their performance characteristics compare?

Yes. That is correct. It is a hollow shaft
