I am wanting to use globe valves for throttling flow in a marine cooling system application instead of an orifice.
But once I adjust the globe valve to the proper position, I want to ensure it can be repositioned to this same height if it gets mistakenly turned. Or a lock to prevent rotation...
The Machinery's Handbook suggested a paper called 'Critical Speeds of Uniform Shafts under Axial Torque' by Golomb and Rosenberg.
Has anyone heard of this paper and know where I can get a copy??
Thanks.
Hello All.
I need to install a new oil pump suction line into the ships existing oil sump for a new engine we are installing. I will be using a bell suction mounted a certain distance above the bottom of the sump.
Are there any rules of thumb or guidelines for bell shape or height above...
I know the ISO tolerancing thing has been discussed to great lengths here but......
I have a 120n6 mm shaft and a 120H7 mm bore.
The website below describes the tolerancing a little differently than what I have read before. Here is how they describe it.
120n6 shows as +45 and +23 in...
I have done some searching for some formulas or general guidlelines on orifice sizing in cooling systems and have come up short.
I will be needing to size several orifices in a large marine application to restrict flow. I plan to use plate style st.st. orifices. Flows from 20m3/hr to 270m3/hr...

Hello all.
I have a solid steel shaft driving a generator from the PTO output on a marine gear. It is rotating at 1820 rpm with max. power transmission of 800kW. The shaft is 5.188" diameter and 84" long.
It looks like critical speed is ok. I believe it is around 3100rpm. The static deflection...
