Optimization of dredge and variable displacement pumps
Conclusions Centrifugal pumps with an adjustable outlet diameter and width of the impeller passage and discharge pipe improve the operation of the netweork and make it possible to reduce energy expenditures at pumping stations by 10–20%.By obtaining clean water directly from the sludge and directly in the pump (without pressure losses) it is possible to solve the problem of protecting pump elements from abrasion by a wall boundary layer without increasing energy expenditures on injecting clean water into the internal cavity of the pump.By fractionation of sludge in pressure settling tanks (without pressure losses) it is possible to use inferior borrow pits near hydrotechnical construction sites for reducing transportation expenditures on delivering inert materials to the site.
