I am putting together the piping specifications for a gold plant in Western Australia. Our governing Standard for Pressure Piping, AS4041 makes extensive reference to ANSI B31.3 Process Piping. Our Std classifies piping into 4 classes according to service, one classification being: (1)Lethal...
Thanks to Kawartha & PumpDesigner for your comments.
I am really after any specific quantitative studies that have measured the drop off in performance against increasing clearance.
I am interested in the 'suction side' ie short circuiting from high pressure to low pressure, but also in any...
Does anyone have any specific knowledge about the effect on the H-Q curve of excessive clearance between the impeller and the back liner/casing of a simple end-suction centrifugal pump?
I presume that internal recirculation will increase and that power goes up without an aparrent increase in...
