What is the value of input shaft floating? I guess if this value is considered more than 0.1 mm, upper SRB could not be fully seated on its housing properly (I think that input shaft thermal expansion is below of this value). This may be the reason of excessive thrust load transfer...
Dear Johnny Pellin
1- According to your experiences, what are the best bearing fits between for upper & lower SRB within their housings?
2- how much percentage can be probably related to the fake bearing?
3- would you explain, how can one diagnose coupling spacing has an incorrect setting?! for...
Dear mkfe2005
It is correct that sundyne mentions that lower seat bearing fitness should be considered +.07 mm, but this value seems to create some problems due to loose fit that causes relative motion between mating parts. In addition, we know that if this relative motion (between Bearing Outer...
Hi all
According to "Impeller eye cavitation damage of sundyne Bulletin", the cavitation damage appears due to overly large inlet eye diameter to impeller tip diameter ratio.
1- what is the eye diameter exactly?! is it inducer diameter?
2- what is the red line in the attached picture?
3-what is...
Hi all
I started LMV322 pump and contentiously open the discharge valve from 25 % to 70 %, all things are OK. Note that in this condition, flow is in rated point. Once i want to open the discharge valve a little more,discharge pressure Gage and Amper monitoring fluctuated and by returning to...
Dear JJpellin:
what is your suggestion to over come this problem (cavitation problem at tip vanes)? does it solve by considering the minimum flow line?
