Abstract
Some aspects of calculation of joint operation of sewage sludge pumps and pipeline networks
Highlights
PUMPS AND PIPELINE NETWORKSThe article considers the issues of joint operation of centrifugal pumps and networks for sewage sludge (SS) the flow of which is described by the Bingham plastic model
Pumping of natural and waste waters by centrifugal pumps consumes up to 150 billion kWh of electricity in the Russian Federation
The calculation of the joint operation of pumping stations and networks is directly related to energy saving and performance reliability improving
Summary
The article considers the issues of joint operation of centrifugal pumps and networks for sewage sludge (SS) the flow of which is described by the Bingham plastic model. The authors present the results of the experimental studies of SS pumps operation and a formula for working out pump performance parameters for SS with different concentrations. To determine the design point of the joint operation of pumps and networks we used the dependence of hydraulic pressure losses in the pipeline by means of generalized Reynolds number taking into account SS viscoplastic properties. The results of experimental and design data for centrifugal SS pump performance parameters are given
