Looking at very large slurry pumps with a high chrome white iron suction liner. We're seeing some very large cracks in the inside/hole/inlet of the suction liner.
Could be many things like, over or under torqued bolts, rapid heating (really cold here), dropped it, large nose gap (more...
Hi
I calculated piping losses earlier using the darcy-weisbach equation between the 30 & 32" line for the design composition and got ~22m of head. Friction factor assumed was .151 from design calc (unsure if this is right)
My question is that now densities are higher (950-1000 kg/m3). How...
We have a froth deaerator, steam goes in to release entrapped air. Following the deaerator are pumps that are struggling, unkown if due to rise in air content.
We don't have an air content measurement before or after. Density before is not very accurate due to high air content.
What I would be...
Came across an interesting study and also read someone's response on a forum a long time ago. It states that by having counter swirl at the inlet (opposite of impeller) you can generate head as flow is increased.
I do not know enough about pumps yet so I found this study...
